Description

Novel plug-in aluminum grid extruder and press

Technical Field

The utility model relates to the technical field of aluminum grid processing, in particular to a novel plug-in aluminum grid extruder and a press.

Background

The traditional aluminum grid extruder is a machine applying the hydraulic principle and is mainly used for processing aluminum alloy materials and manufacturing products such as aluminum grids. The technology is widely applied, and has important application in the fields of construction, traffic, ships, machinery and the like.

Among them, the conventional aluminum grid extruder is generally composed of a main part of a frame, a hydraulic system, a ram, a die, and the like. The device is used as a core mechanism in an aluminum grid processing press;

the working principle is simpler: the press consists of an extruder, a heating furnace and an extrusion die. During extrusion, the aluminum material is softened by heating and then pressed into an extrusion die to form a desired grid shape. The extruder is provided with sufficient pressure by a hydraulic system to push the aluminum material through the extrusion die. The heating furnace is used for heating the aluminum material to reach a proper softening temperature so as to form a required shape in the extrusion die. Extrusion dies are the most important component of the extrusion system and are designed and manufactured according to the desired grid shape to ensure that the aluminum material is properly shaped during extrusion.

The aluminum grille which is formed by extruding the heated aluminum alloy material into the die through the hydraulic system driving pressure head has the advantages of high strength, corrosion resistance, fire resistance, attractive appearance and the like, and has wide application prospect. With the continuous development of technology, the extrusion technology of aluminum grids is also continuously improved and improved. The modern aluminum grid extruder has higher automation degree and processing precision, and can realize more efficient and finer aluminum grid production. At the same time, the application of the novel materials and the novel process also brings new opportunities and challenges for the development of the aluminum grid extrusion technology.

The inventor has long-term work found that the existing aluminum grid extruder has the following technical problems:

(1) The production efficiency is low: conventional aluminum grid extruders generally require a large number of manual operations and have low production efficiency and are not capable of meeting large-scale production requirements.

(2) The product precision is low: the traditional aluminum grid extruder has lower process precision, and the processed aluminum grid product has a certain size error and cannot meet the application requirement of high precision.

(3) The die is difficult to replace: conventional aluminum grid extruders are typically only capable of production using one or more shaped molds, and if a different shaped mold needs to be replaced, the replacement will need to be stopped, resulting in a low production efficiency.

Therefore, a novel plug-in aluminum grid extruder and a press machine are provided.

In the prior art, the traditional extruder and press have the technical problems of low production efficiency, low product precision and difficult die replacement; for this reason, referring to fig. 1-5, the present utility model provides a technical solution to solve the above technical problems: a novel plug-in aluminum grid extruder and press comprises a hydraulic cylinder 104 and an extrusion die connected with a piston rod of the hydraulic cylinder, and comprises an extruder component 1; the extruder assembly 1 outputs three linear degrees of freedom along the same Y-axis annular array but different output axes, acting on the hydraulic cylinder 104 for universal angular adjustment.

In the scheme, the linear degree of freedom and the degree of freedom of the hydraulic cylinder 104 are in linkage relation, are in a direct driving mode, and finally realize linkage driving of driving multiple degrees of freedom, and are specific in driving track, azimuth, angle and other parameters; specifically, the stroke amount model selection assembly based on the degrees of freedom is realized based on the staff, and the linkage between the degrees of freedom and the control of an external controller are realized.

Specifically, the extruder assembly 1 includes an annular array and three linear motion members, the annular array being on the same Y axis, the annular array having the three linear motion members fixed thereto. The three linear motion components move along different output axes, and the motion directions are mutually perpendicular. The advantage of this design is that three linear degrees of freedom in different directions can be achieved. The hydraulic cylinder 104 is connected to the extrusion die through a piston rod, thereby realizing extrusion molding of the aluminum grid.

It will be appreciated that in this embodiment, different angular adjustments to the extrusion die may be achieved by adjusting the position of the linearly moving parts in the extruder assembly 1. And because the three linear motion components are on the same Y axis and are connected with each other through the annular array, the universal angle adjustment of the hydraulic cylinder 104 can be realized. The novel plug-in aluminum grid extruder has the main function of realizing more accurate and flexible angle adjustment, thereby better meeting the molding requirements of aluminum grids with different shapes and sizes.

In some embodiments of the present utility model, please refer to fig. 3 in combination: the extruder assembly 1 comprises an upper disc body 101 and a lower disc body 102 which are vertically corresponding; the upper disc body 101 and the lower disc body 102 are taken as central axes along the same Y axis, one surfaces of the upper disc body 101 and the lower disc body 102, which correspond to each other, are respectively hinged by cylinder bodies and piston rods of three telescopic cylinders 103 outputting linear degrees of freedom, and the telescopic cylinders 103 are uniformly distributed along the central axes of the upper disc body 101 or the lower disc body 102 in an annular array manner; the lower disc 102 is fixedly connected to the lower end of the cylinder body of the hydraulic cylinder 104, and the upper end of the cylinder body of the hydraulic cylinder 104 is in universal hinge joint with the upper disc 101.

Specifically, the upper disc 101 and the lower disc 102 are connected together by a piston rod of a telescopic cylinder 103, and the cylinders are arranged in an annular array along the same Y axis. By controlling the telescopic length of the telescopic cylinder 103, the height adjustment of the extrusion die can be achieved. The upper tray 101 is connected with the upper end of the cylinder body of the hydraulic cylinder 104, and the lower end of the cylinder body of the hydraulic cylinder 104 is fixedly connected with the lower tray 102, so that when the piston of the hydraulic cylinder 104 moves upwards or downwards, the piston drives the upper tray 101 to move upwards or downwards through the hinge point, and the pressing and releasing of the extrusion die are realized.

By the design of the above structure, the extruder assembly 1 can have three linear degrees of freedom in the Y-axis direction, which allows the extrusion die to be adjusted in different directions. Due to the uniform distribution of the telescopic cylinders 103, the extrusion die can be kept stable, and unstable conditions caused by adjustment in a certain direction can be avoided.

It will be appreciated that in this embodiment, the lower disc 102 is fixedly connected to the lower end of the cylinder body of the hydraulic cylinder 104, which means that movement of the piston rod of the hydraulic cylinder will cause the lower disc 102 and the extrusion die thereon to be extruded. Meanwhile, the aluminum material in the extrusion process is adjusted.

The universal joint coupling is typically composed of two U-shaped bearings and a central universal joint that allows the two shafts to freely rotate and flex in multiple directions while transmitting torque. Thus, the aluminum grid can be extruded along different axes, and more diversified shape processing is realized.

The hemispheres have raised spherical projections on their surfaces which slide and rotate as the hemispheres rotate, thereby providing a universal connection of the cylinder 104 to the upper disc 101. Such a coupling may provide three degrees of freedom: rotating about X, Y and the Z axis. Thus, the aluminum grid extruder can be adjusted in multiple directions and adapted to different workpiece shapes and sizes.

Preferably, the telescopic cylinder 103 is preferably a servo cylinder, and the cylinder body and the piston rod of the servo cylinder are hinged to the corresponding surfaces of the upper disc 101 and the lower disc 102 through universal joint couplings 1031, respectively.

The cylinder body and the piston rod of the servo electric cylinder are hinged with the corresponding surfaces of the upper disc body 101 and the lower disc body 102 through the universal joint coupling 1031, so that the extrusion die can realize free movement in multiple directions, and higher precision requirements are met. Meanwhile, the servo electric cylinder is provided with an automatic feedback mechanism, and can be adaptively adjusted according to real-time feedback information, so that the extrusion process is more stable and reliable.

In this embodiment, the extrusion die comprises one or more of any combination of rectangular, square, triangular, trapezoidal or arc-shaped dies. The extrusion die is a tool used for shape forming in an aluminum grid extruder. They may be rectangular, square, triangular, trapezoidal or arcuate molds of different shapes, or any combination thereof. This means that the aluminum grid extruder can use a variety of dies to create different shapes and sizes to meet different application requirements. The choice of mould can also be optimised according to the desired yield and production efficiency.

The above is a principle of the extruder and the mechanical aspect of the press using the extruder provided in this embodiment. The following description will provide the extruder and the principle of use of the extruder in the press machine according to the present embodiment:

exemplary: application of extruder Assembly 1:

(1) In order to produce a relatively flat, aluminum grid product without significant tilting, the stroke amounts of all servo cylinders can be set to the same value, for example 50cm. This will equalize the angles of the four corners of the processed aluminum grid product, approximately 90 degrees.

(2) If one wants to make an aluminum grid product that is tilted to the left, one can set the stroke amount of the servo cylinder on the right to a larger value, for example 80cm, and the stroke amount of the servo cylinder on the left to a smaller value, for example 20cm. This will make the left side corner of the processed aluminum grid product sharper and the right side corner flatter.

(3) If one wants to make an aluminium grid product inclined to the right, one can set the stroke amount of the servo cylinder on the left to a larger value, for example 80cm, and the stroke amount of the servo cylinder on the right to a smaller value, for example 20cm. This will make the right side corner of the processed aluminum grid product sharper and the left side corner flatter.

(4) If it is desired to make an upper inclined aluminum grid product, the stroke amount of the lower servo cylinder may be set to a larger value, for example 80cm, and the stroke amount of the upper servo cylinder may be set to a smaller value, for example 20cm. This will make the lower corners of the processed aluminum grid product sharper and the upper corners flatter.

(5) If it is desired to make a lower inclined aluminum grid product, the stroke amount of the upper servo cylinder may be set to a larger value, for example 80cm, and the stroke amount of the lower servo cylinder may be set to a smaller value, for example 20cm. This will make the upper corners of the processed aluminum grid product sharper and the lower corners flatter.

To further demonstrate the utility of the extruder assembly 1, an exemplary simulated use environment is next to be brought into calculation:

it is assumed that an aluminum grid having an inclination angle θ is required to be processed, wherein the rectangular mold has a side length L, the aluminum material has a length H, the coefficient of friction between the mold and the aluminum material is μ, and the contact area between the mold and the aluminum material is a. According to the principle of physics:

when the pressing force F exerted on the mold exceeds the friction force F _f ＝μF _N At this point, the die will begin to extrude the aluminum downwardly. Wherein FN is the normal force between the die and the aluminum material. Thus, the following equation can be obtained:

F＞μF _N

also, because the process of extruding aluminum downwardly from the die can be regarded as an equivalent problem to sliding along the upper inclined surface of the die, the tangential force to which the aluminum is subjected is:

F _t ＝Fsinθ

the normal force is:

F _N ＝Fcosθ

bringing these two forces into the above equation yields:

F＞μFcosθ

the lower limit of the solving extrusion force F is as follows:

next, the extrusion angle α corresponding to the stroke amount of the parallel mechanism is calculated. Assuming that the displacement of each servo cylinder is X, the total displacement of the parallel mechanism is x=3x. In the processing process, the sliding distance D of the aluminum material on the die is as follows:

during sliding, the resultant force applied to the aluminum material can be decomposed into a force component FN 'perpendicular to the sliding direction and a force component Ft' parallel to the sliding direction. Since the contact between the aluminum material and the mold is point-to-point, the size of FN' can be considered constant. According to newton's second law:

F _t ′＝Fsin(θ-α)-F′ _N tanα

the sliding speed of the aluminum material is as follows:

where t is the time of the slip. Since the mold is stationary during sliding, the friction on the mold can be approximately considered constant, i.e.:

Ff＝μFN′

considering that the aluminum material is stable during processing, it is required to satisfy the following conditions:

Ft′＝Ff

substituting the above formula can give:

substituting Ft' =ff, gives:

ff is represented by Fc and Ft, yielding:

and (3) transferring and sorting to obtain:

thus, the expression of s_1 can be derived:

wherein S0 is the sectional area of the die outlet, fc is the pressure of the press, and Ft is the friction force. This formula tells that by adjusting the pressure and friction of the press, the die entrance cross-sectional area S0 and exit cross-sectional area S1 can be determined, thereby achieving the processing of the aluminum grid product. Thus, the formula may be brought into the controller as a core algorithm.

Specifically, the controller is an MCU controller, the servo cylinder is controlled by the raspberry group, and the control operation of the extruder assembly 1 is realized by adopting a Python code and controlling a circuit board on the raspberry group by the GPIO, and the operation principle of the code is explained with reference to fig. 4, in which comments are made.

It will be appreciated that the source code described above may be iterated further. Through continuous adjustment parameters and optimization algorithm, the precision and efficiency of the extruder can be improved, more functions and automatic control can be added, the production efficiency is improved, and the labor cost is reduced. For example, real-time monitoring and feedback control can be added, parameters and an optimization algorithm can be dynamically adjusted according to actual production conditions, and the product quality and the production efficiency are further improved. In addition, the function of adding an automatic adjusting die can be considered, the size and the shape of the die can be automatically adjusted according to different product specifications and requirements, one machine with multiple functions is realized, the production efficiency is further improved, and the cost is reduced.

Furthermore, based on the output parameters of the servo electric cylinders corresponding to the aluminum grid forming with different specifications, which are preset, the output parameters are used as a preset library, and the preset library is brought into the codes, so that more automatic production is realized. Fig. 5 to 6 are updated code forms, and can be automatically produced according to output parameters of servo electric cylinders corresponding to aluminum grid molding of different specifications in a preset library: when different specification parameters are input, the code searches preset parameters matched with the input parameters from a preset library, and then the parameters are transmitted to the code for controlling the servo electric cylinder so as to realize the production of the aluminum grid with corresponding specification. The variable params represents a preset library, input_params represents an input parameter, and matched_params represents a matched preset parameter. The find_matching_parameters function in the code is used for searching preset parameters matched with the input parameters in a preset library, returning the matched preset parameters, and returning to None if the matched preset parameters are not available.
