FIG. 1 is a schematic illustration of a pipe bender according to some embodiments of the present specification.

As shown in FIG. 1, the present embodiments provide an automated pipe bender. The automated pipe bender may include: a guide die 1, a clamping die 2 and a bending die 3. Other components and connections in the figures may be provided as embodiments, and corresponding parts may be omitted or implemented in other ways in some embodiments. Exemplary embodiments of the various components of an automated pipe bender are described in greater detail below in conjunction with fig. 1-6.

The guide die 1 may refer to a member for limiting a pipe. In some embodiments, the guide die 1 may be a limit groove. In some embodiments, the guide die 1 may be a stopper. At least two limiting blocks are fixed at specific positions to limit the pipe. The guide die 1 may also be of other forms.

Fig. 2 is a side view of a guided mode shown according to some embodiments of the present description.

In some embodiments, the guided mode 1 may comprise at least two guided mode assemblies 11. In some embodiments, as shown in fig. 2, the guided die 1 may include four guided die assemblies 11.

The guide die assembly 11 may refer to the components constituting the guide die 1. In some embodiments, the guide mold assemblies 11 are provided with arc-shaped grooves 12, and the arc-shaped grooves 12 of at least two guide mold assemblies 11 can be movably spliced to form a space for clamping the pipe.

The arcuate groove 12 may be referred to as a groove having a curvature. The arc of the arcuate groove 12 may be determined in a variety of ways. For example, it may be determined based on the number of the guide mold assemblies 11, and the more the guide mold assemblies 11 constituting the guide mold 1, the smaller the arc radian of the arc-shaped groove on the guide mold assembly 11. For another example, the determination may be made based on historical experience, actual demand, and the like.

In some embodiments, the arcuate grooves 12 of at least two of the guide die assemblies 11 can be movably engaged in a variety of ways to form a space for gripping a pipe. For example, at least two guide die assemblies 11 can be connected with a control device respectively, and the guide die assemblies 11 are directly controlled by the control device to realize movable splicing;

for another example, at least two guide mold assemblies 11 may be connected by a telescopic structure, and then the telescopic structure is connected to a control device, and the control device is used to indirectly control the guide mold assemblies 11 by controlling the telescopic structure to realize movable splicing and the like. The control device can be a device for independently controlling the guide die assembly, and can also be a centralized control system of an automatic pipe bending machine. The telescopic structure refers to a structure capable of adjusting the length of telescopic, such as a telescopic spring, a hydraulic cylinder and the like. The centralized control system may refer to a complete machine control system for controlling the components of the automated pipe bender.

In some embodiments, when the automated pipe bender is in operation, the guide die 1 can adjust the guide die assembly 11 in various ways based on the pipe diameter of the pipe, and the guide die assembly can be movably spliced to form a space suitable for different pipe diameters. For example, the guide module 11 is directly adjusted by the control device or the like. In some embodiments, the initial state of the at least two guide die assemblies 11 may be that the guide die assemblies 11 are at a telescopic maximum value, when the pipe is detected to be conveyed into the guide die 1, the at least two guide die assemblies 11 shrink at a constant speed at the same time, and when the contact between the guide die assemblies 11 and the outer wall of the pipe is detected, the control device controls the guide die assemblies 11 to stop shrinking, so that the pipe with different specifications and different pipe diameters is clamped. Among them, the detection mode includes but is not limited to a distance sensor and the like.

The clamping die 2 may refer to a member for applying a force to the pipe to bend the pipe. In some embodiments, the structure of the clamping mold 2 may be the same as that of the guiding mold 1, or may be different from that of the guiding mold 1, and may be based on practical situations.

Fig. 3 is a side view of a clamping die according to some embodiments of the present description.

In some embodiments, the clamping die 2 may include at least two clamping die assemblies 21. In some embodiments, as shown in fig. 3, the clamping die 2 may include four clamping die assemblies 21.

The clamping die assembly 21 may refer to the components that make up the clamping die 2. In some embodiments, the clamping die assemblies 21 are provided with arc-shaped notches 22, and the arc-shaped notches 22 of at least two clamping die assemblies 21 can be movably spliced to form a space for clamping the pipe.

The arcuate slot 22 may refer to a slot having a certain arc. In some embodiments, the arcuate curvature of the arcuate slot 22 may conform to the arcuate curvature of the arcuate groove 22 on the guide assembly 21. Likewise, the arc of the arcuate slot 22 may be determined based on a variety of ways. For example, the determination may be made based on the number of clamping die assemblies 21, the more clamping die assemblies 21 that make up the clamping die 2, the smaller the arc of the arcuate slot 22 in the clamping die assembly 21. For another example, the determination may be made based on historical experience, actual demand, and the like.

In some embodiments, the arcuate slots 22 of at least two clamping die assemblies 21 may be movably engaged in a variety of ways to form a space for clamping a pipe. For example, the movable split can be realized by directly connecting at least two clamping die assemblies 21 to a control device, and directly controlling the clamping die assemblies 21 by using the control device; for another example, the movable split and the like may be achieved by connecting between at least two of the guide die assemblies 21 with a telescopic structure, and then connecting the telescopic structure to a control device, and indirectly controlling the clamp die assemblies 21 by controlling the telescopic structure with the control device.

Likewise, in some embodiments, when the automated pipe bender is in operation, the clamping die 2 can adjust the clamping die assembly 21 in a variety of ways based on the size of the pipe diameters, movably spliced to form a space adapted to the size of the different pipe diameters. For example, the initial state of the at least two clamping die assemblies 21 may be that the clamping die assemblies 21 are at a telescopic maximum value, when one end of a pipe is detected to be conveyed into the clamping die 2, the at least two clamping die assemblies 21 shrink at a constant speed, and when the clamping die assemblies 21 are detected to touch the outer wall of the pipe, the control device controls the clamping die assemblies 21 to stop shrinking, so that pipes with different specifications and different pipe diameters are clamped. For another example, the clamping die assembly 21 can be directly adjusted by the control device to form a clamping space adapted to different pipe diameters, etc.

In some embodiments, the clamping die 2 is also connected with a power device 4.

The power means 4 may be means for powering the movement of the clamping die 2. For example, a servo motor, a hydraulic pump, etc.

In some embodiments, the power device 4 may drive the clamping die 2 to rotate around the bending die 3, so as to apply a force to the pipe clamped by the clamping die 2 to bend the pipe into a shape. When the centralized control system detects that the clamping die 2 clamps one end of the pipe, namely, the power device 4 is controlled to drive the clamping die 2 to rotate around the bending die 3, the pipe clamped by the clamping die 2 can be bent and formed due to the structure and the limiting function of the clamping die 2 and the bending die 3.

The bending die 3 may refer to a member for bending a pipe, preventing deformation of the bent portion of the pipe, and securing a bending radius. The structure of the bending die 3 is not limited and may be cylindrical, roller-shaped, or the like. As shown in fig. 1, the bending die 3 may have a cylindrical shape, and the bending die 3 may include one or more adjustment structures 31.

Fig. 4 is a front view of an adjustment structure shown in accordance with some embodiments of the present disclosure.

The adjusting structure 31 is a structure that can adjust the size of the bending die. In some embodiments, the adjustment structure 31 may have a disc shape, and the diameter of the cylindrical bending die 3 is adjusted by adjusting the diameter of the adjustment structure 31. As shown in fig. 4, the adjustment structure 31 may include a connection mechanism 311, a plurality of first fan mechanisms 312, and a plurality of second fan mechanisms 313. The first fan-shaped mechanism 312 and the second fan-shaped mechanism 313 are alternately arranged around the connecting mechanism 311, and the first fan-shaped mechanism 312 and the second fan-shaped mechanism 313 are respectively movably connected with the connecting mechanism 311, so that the first fan-shaped mechanism 312 and the second fan-shaped mechanism 313 can move along the radial direction close to or far away from the connecting mechanism 311, and the second fan-shaped mechanism 312 can change the fan-shaped area of the second fan-shaped mechanism by changing the arc length so as to realize the adjustment of the size of the bending die 3.

The connection mechanism 311 may refer to a member for connecting the first sector mechanism 312 and the second sector mechanism 313. The connection mechanism 311 may have a variety of structures or forms including, but not limited to, a column, a cylinder, etc. In some embodiments, the connection mechanism 311 may be movably connected to the first fan mechanism 312 and the second fan mechanism 313 by a telescopic structure (e.g., a telescopic spring, a hydraulic cylinder, etc.), and the contractibility of the telescopic structure is used to control the first fan mechanism 312 and the second fan mechanism 313 to move together in a radial direction toward or away from the connection mechanism 311. In some embodiments, the first and

second scallops

312, 313 together move radially closer to the connection 311, enabling the adjustment structure 31 to be smaller in diameter, with a corresponding smaller diameter for the bend die 3 or portion of the bend die 3. In some embodiments, the first and

second scallops

312 and 313 together move radially away from the connection 311, enabling the adjustment structure 31 to be larger in diameter, corresponding to the larger diameter of the bending die 3 in whole or in part, to accommodate the need for larger bending radii.

In some embodiments, "articulating" includes, but is not limited to, detachable connections, and the like. In some embodiments, the first and second fanning

mechanisms

312, 313 are detachably connected to the telescoping structure on the connection mechanism 311 by a snap, screw fit, or the like; the first and

second sector mechanisms

312, 313 are removable from the telescopic mechanism by removable connection to allow for easy individual replacement of a portion of the wear components.

The first sector mechanism 312 may refer to the component of the adjustment structure 31 that is primarily in contact with the process tube. In some embodiments, the first fan mechanism 312 may have a fan-shaped structure formed by two straight lines and one arc line, or may have a fan-shaped structure formed by two straight lines and two arc lines with different arc lengths. The number of first sector mechanisms 312 is not limited and may be determined based on experimentation, simulation, etc. For example, for larger sized adjustment structures 31, more first fan mechanisms 312 may be included correspondingly.

The second scalloping mechanism 313 may be for filling the arc length between the first scalloping mechanisms 312 such that the first scalloping mechanism 312 and the second scalloping mechanism 313 form a complete disc-shaped adjustment structure 31. Likewise, in some embodiments, the second fan mechanism 313 may have a fan-shaped structure formed by two straight lines and one arc, or may have a fan-shaped structure formed by two straight lines and two arcs with different arc lengths. The number of second scallops 313 may be based on the number of first scallops 312. For example, the number of first fan mechanisms 312 is 3, and the number of second fan mechanisms 313 should also be 3.

In some embodiments, the first fanning mechanism 312 and the second fanning mechanism 313 may each be fanned with the same fanning radius and alternately disposed around the circumference of the connection mechanism 311, i.e. a disc-shaped adjustment structure 31 may be formed.

Fig. 5 is a front view of a second fanning mechanism according to some embodiments of the present disclosure.

As shown in fig. 5, in some embodiments, the second fanning mechanism 313 may include a base 3131 and two components, namely a component 31321 and a component 31322. Wherein the base member 3131 may refer to a base member constituting the second sector mechanism 313; the assembly may refer to an auxiliary member to constitute the second sector mechanism 313. In some embodiments, base 3131 and

components

31321 and 31322 are all scalloped and have the same radius, and

components

31321 and 31322 are movably disposed on both radial sides of base 3131, respectively, to vary the arc length of second scallop mechanism 313 to enable filling of the portion between first scallops 312. Illustratively, when the diameter of the adjustment structure 31 is incrementally adjusted, the first and

second scallops

312, 313 move radially away from the connection 311 together, causing a gap between the first and

second scallops

312, 313, and the arc length of the second scallops 313 can be increased by the

assemblies

31321, 31322, thereby filling the gap portion.

In some embodiments, "activity settings" may include, but are not limited to, a telescopically coupled connection, or the like. For example, connection is made by a telescopic structure or the like. By telescopically coupling, it is ensured that both components can be stretched from the radial side of the base member 3131 to the radial side of the adjacent first scallop 312 to ensure that the gap in the diameter of the first scallop 312 can be completely filled by the second scallop 313, thereby enabling the tubing to conform to the bending die 3 and avoiding deformation of the tubing during bending other than the desired bending.

In some embodiments, the two components may be respectively connected with the base 3131 through the elastic member 3133, and the two components are respectively abutted with the radius sides of the adjacent first sector mechanisms 312 through the elastic member 3133. Here, the elastic member 3133 may refer to a contractible member such as a contractible spring or the like.

In some embodiments, when the adjustment structure 31 is extended to increase the radius, the first fanning mechanism 312 and the second fanning mechanism 313 will extend together in a radial direction away from the connecting mechanism 311, and at this time, the

components

31321 and 31322 of the second fanning mechanism 313 will extend to the radius side of the first fanning mechanism 312 adjacent to each other until abutting against the radius side of the first fanning mechanism 312, so as to supplement the gap between the first fanning mechanism 312 and the second fanning mechanism 313 due to the extension, so that the adjustment structure 31 forms a disc shape, so that the pipe can completely fit the bending die 3, and the deformation of the pipe except bending is avoided when the pipe is bent, thereby achieving the required bending effect.

In some embodiments, the plurality of adjustment structures 31 are movably coupled by the coupling mechanism 311 in a direction perpendicular to the direction of movement of the first and second fanning

mechanisms

312, 313. That is, it can be understood that the plurality of adjusting structures 31 are in an overlapped state and are movably connected by the connecting mechanism 311 to form the bending die 3. Wherein, a certain gap can be provided between the plurality of adjusting structures 31, so that the adjusting structures 31 can move in a radial direction far away from or close to the connecting mechanism 311 better, thereby realizing the adjustment of the size of the bending die 3 and adapting to different bending radius requirements.

It should be noted that the number of the adjustment structures 31 connected by the connection structure 311 and the gap value between the plurality of adjustment structures 31 may be determined based on simulation, experiment, or the like. More adjusting structures 31 can enable the bending die 3 to be suitable for pipes with larger pipe diameters; in the overlapping direction, the superposition of the plurality of adjusting structures 31 with thinner thickness can enable the bending die 3 to have higher precision, can be attached to the pipe as much as possible, and avoid deformation when the pipe is bent. In some embodiments, the connection structure 311 may be individually removed when a particular adjustment structure 31 needs to be individually replaced.

As shown in fig. 6, the plurality of adjusting structures 31 are movably connected by a connecting mechanism 311, so as to form the bending die 3. In some embodiments, when the automatic pipe bending machine works, the bending die 3 can pertinently adjust the radius of each adjusting structure 31 based on production requirements to form grooves with different radians, adapt to the sizes of different pipe diameters and meet different bending radius requirements.

For example, when the bending radius is unchanged and pipes with different pipe diameters are required to be bent and formed, the central control system can be used to adjust the radius of the adjusting structure 31 at the middle position and the radius of the adjusting structure at the two ends of the bending die 3 (i.e. the front end and the rear end of the connecting mechanism 311) from small to large, so that grooves with different radians (i.e. corresponding to the pipe diameters of different pipes) can be formed. The smaller the radian of the groove is, the larger the corresponding pipe diameter is, and the larger the radian of the groove is, the smaller the corresponding pipe diameter is.

For another example, when the pipe diameter of the processed pipe is unchanged and the bent pipe with different bending radius needs to be produced, the centralized control system can simultaneously adjust the radius of each adjusting structure 31 to stretch or shrink at a uniform speed based on the groove corresponding to the pipe diameter size formed by each adjusting structure 31, so as to adjust the bending radius. When the respective adjustment structures 31 are simultaneously extended, the bending radius of the bending die 3 becomes large, and when the respective adjustment structures 31 are simultaneously contracted, the bending radius of the bending die 3 becomes small.

It should be noted that, the centralized control system performs targeted adjustment on each adjustment structure 31 to form grooves with different radians (i.e., corresponding to the sizes of different pipe diameters), and the specific adjustment strategy may be determined based on a preset rule. The preset rule may be a preset adjustment rule. For example, the preset rule may be a mapping relationship based on the size of different pipe diameters or the distance of the bending radius required to extend or retract each adjustment structure 31, and so on.

In some embodiments of the present disclosure, by adopting the plurality of adjusting structures 31 to form the bending die, dynamic adjustment of the radian of the groove and the bending radius of the bending die 3 can be achieved, so that the purposes of processing pipes with different pipe diameters and producing bent pipes with different bending radii can be achieved without changing the die, and the production efficiency is improved.

For example, when bending a pipe, the guide die 1 is used for limiting the initial position of the pipe, the pipe is clamped by the clamping die 2, and under the action of the power device 4 of the clamping die 2, the clamping die 2 applies an acting force to the pipe, so that the pipe bends around the bending die 3.

In some embodiments, the automated pipe bender may include a pipe conveying apparatus (not shown). The pipe conveying apparatus may refer to an apparatus for automatically conveying a pipe. The tubing transport device may be a device made up of multiple components. In some embodiments, the tubular conveying apparatus may include a drive apparatus (e.g., a servo motor, etc.) for providing a driving force for tubular conveyance. In some embodiments, the tube conveying device may include a feeding device (e.g., a conveying table, etc.) for driving the tube to move toward the die 1.

In some embodiments, the tubing conveying apparatus may further comprise a pinch grip. A pinch grip may refer to a device for gripping a tube. In some embodiments, the inner diameter of the pinch grip may be adjustable for gripping pipes of different pipe diameter sizes. Illustratively, the initial state of the pinch grip may be an inner diameter maximum that begins to shrink when the pinch grip contacts the pipe so as to be able to grip the pipe. In some embodiments, the pipe conveying apparatus may be provided with one gripper or a plurality of grippers.

In some embodiments, the centralized control system may automatically adjust the dimensions of the dies (e.g., guided die, clamped die, bent die) based on the pipe diameter of the pipe gripped by the gripping clips.

In some embodiments, the automated pipe bender may include a guide core (not shown). The guide core may refer to a part for preventing deformation when the pipe is bent.

In some embodiments, the guide core may be a smooth cylindrical structure, and the dimension of one end of the guide core (the end near the guide die) may be changed accordingly based on the pipe diameter of the pipe, while the dimension of the other end of the guide core (the end near the pipe conveying device) is always unchanged.

In some embodiments, the guide core is disposed inside the pipe, and one end of the guide core is detachably connected to the pipe conveying device. "removable connection" includes, but is not limited to, threaded connection, snap connection, and the like. In some embodiments, when pipes with different pipe diameters need to be processed, the corresponding guide core can be replaced by a grabbing clamp or a mechanical arm and other devices. For example, the guide core is connected with the pipe conveying device based on threads, when pipes with different pipe diameters are required to be processed, the guide core is unscrewed from the pipe conveying device by utilizing a grabbing clamp or a mechanical arm and then screwed into the pipe conveying device, and then the guide core with corresponding size is grabbed.

In some embodiments, the centralized control system can also automatically replace the guide core based on the pipe diameter of the pipe clamped by the grabbing clamp.

In some embodiments, the automated pipe bender may further include a lubrication mechanism (not shown). The lubrication mechanism may refer to a mechanism for lubricating the guide core. For example, the lubrication mechanism may be a lubrication box, a lubrication ring, a lubrication sump, or the like, containing a lubricant. In some embodiments, the guide core may be lubricated in a lubrication mechanism prior to installation so that the guide core may smoothly enter the tubing.

In some embodiments, the automated pipe bender may further comprise a die wear inspection system. The mold wear inspection system may refer to a system for detecting the degree of wear of each adjustment structure 31 in the bending mold 3.

In the bending process of the pipe, the wear degree corresponding to different operations is different, for example, the adjusting structures 31 of the bending die 3 can be adjusted to form grooves with different radians for different pipe, that is, different operations are corresponding to different pipe, so that the use frequency of the different adjusting structures 31 is different, and the wear degree is different; the wear level of the different fan-shaped structures (e.g., first fan-shaped structure, second fan-shaped structure) in each adjustment structure 31 is also different. Based on the abrasion condition of the pipe to the die in the pipe bending process, the adjusting structure 31 with abrasion to the radian can rotate to change the contact position of the die and the pipe so as to avoid the abrasion position, and after the abrasion in all directions is uniform, the corresponding structure is replaced without replacing all the structures. In some embodiments, individual adjustment structures 31 may be replaced according to wear conditions to reduce mold replacement costs.

In some embodiments, based on the mold wear inspection system, the step of determining the degree of wear of different fan structures in each adjustment structure 31 corresponding to different operations may include:

s1: obtaining the number C of different operations of each fan-shaped structure i _i1 ，C _i2 ，...，C _in . Wherein C is _in Representing the number of ith scallops required to perform the nth operation.

In some embodiments, there may be a number of ways to obtain the number of different operations performed by the fan-shaped structure. For example, it may be obtained directly from a centralized control system; for another example, the acquisition may be performed by providing an image acquisition device (e.g., a camera, etc.), using a technique such as image recognition, etc.

S2: obtaining the total abrasion degree D of each fan-shaped structure _i 。

The degree of wear may be used to reflect the degree of wear of each fan-shaped structure. For example, D2 may be the amount of line wear after a unit time (e.g., 1 month) of use of the 2 nd fan structure (e.g., the second fan structure). In some embodiments, the total wear level of each fan structure may be obtained based on image recognition techniques. For example, the amount of line wear after use, etc. may be determined based on comparison of the bending image before use with the bending image after use per unit time.

S3: assume that each of the class i scallops has a degree of wear F for operation j _ij Then can be based on D _i ＝∑C _ij ×F _ij Solving for F _ij 。

In some embodiments, based on the above formula, F may be solved using a variety of methods _ij . For example, the solution may be based on a multivariate equation, a particle swarm algorithm, or the like.

In some embodiments, when solving based on the particle swarm algorithm, the total wear level of each fan-shaped structure may be calculated based on the solved candidate solution and the known D _i And the difference value is used as an evaluation value to be optimized, and a better solution is obtained through multiple rounds of iteration.

S4: based on the solved F _ij The abrasion degree of each fan-shaped structure at different time is estimated, so that detection, adjustment and replacement are performed.

In some embodiments, the F may be based on the solution _ij The wear degree of each fan-shaped structure at different times is estimated by setting the target time period T. For example, the degree of wear of the 1 st fan-shaped structure (e.g., the first fan-shaped structure) at the target time length is D ₁ ＝∑T×F _1j 。

In some embodiments, when the degree of wear of the fan-shaped structure meets a predetermined condition, the fan-shaped structure may be determined to be one that requires detection, adjustment, or replacement. The preset condition may be a preset replacement condition, for example, the preset condition may be that the wear degree of the fan-shaped structure has exceeded a wear degree threshold value under the target time period T, or the like.

For example, when the mold wear detection system determines that the wear degree of a certain fan-shaped structure exceeds the wear degree threshold value under the target duration T, a warning message (such as a warning sound, a warning text, etc.) may be sent to remind the user to detect the bending mold 3, and adjust the acting position (such as rotating for half a cycle) of each adjustment structure 31 (or a single adjustment structure) on the bending mold 3, so as to avoid the wear area and replace other unworn areas for continuous use, and when the user finds that each adjustment structure 31 (or a single adjustment structure) on the bending mold 3 is worn in each direction, each adjustment structure 31 (or a single adjustment structure) may be replaced.

In some embodiments, to maintain consistent wear of the fan-shaped structures in the adjustment structure 31 for a target period of time in order to extend the useful life of the adjustment structure 31, the fan-shaped structures in the adjustment structure 31 may be customized based on user needs.

In some embodiments, a method of customizing a fan-shaped structure based on user requirements may include: the method comprises the steps of firstly carrying out abrasion test on an adjusting structure 31 (at the moment, a first fan-shaped mechanism and a second fan-shaped mechanism are made of the same material) of various materials under the target duration, and determining abrasion values of the materials; determining the ratio of the time duration of use of the first fan mechanism 312 to the second fan mechanism 313 in the adjustment structure 31 based on the user's demand; and finally, determining the material corresponding to the fan-shaped structure based on the abrasion value of each material and the fan-shaped structure (namely, the first fan-shaped mechanism and the second fan-shaped mechanism). The wear value of each material may be determined based on the total wear degree of the adjusting structure 31 obtained by the mold wear detection system, for example, the wear degree value is directly determined as the wear value; the ratio of the length of use of the first sector 312 to the second sector 313 in the adjustment structure 31 may be obtained based on historical data.

For example, the wear values of the material A, B, C are respectively 0.2, 0.4 and 0.8, and the usage duration ratio of the first fan mechanism 312 to the second fan mechanism 313 is determined to be 2:1, the first fan mechanism 312 may be made of material a, and the second fan mechanism 313 may be made of material B; or the first fan mechanism 312 may be made of material B and the second fan mechanism 313 may be made of material C.

In some embodiments of the present disclosure, by using the die wear detection system, the fan-shaped structures on the plurality of adjusting structures 31 of the bending die 3 can be detected for wear, which is favorable for a user to detect the bending die 3 in time, so as to adjust or replace the adjusting structures 31, thereby effectively ensuring the processing quality when bending the pipe, and meanwhile, pertinently adjusting or replacing the adjusting structures 31, so that the user cost can be saved. In addition, based on user's demand, individualized custom mold can satisfy the different processing demands of different users, also can help the user to save the cost.
