Description

A beam forming mechanism for automobile manufacturing

Technical Field

The invention relates to the technical field of automobile crossbeam processing, in particular to a crossbeam forming mechanism for automobile manufacturing.

Background Art

The frame is a frame structure that spans the front and rear axles of the car, commonly known as the beam, and is the base of the car. It is generally composed of two longitudinal beams and several cross beams, and is supported on the wheels through the suspension device, the front axle, and the rear axle. The frame must have sufficient strength and rigidity to withstand the load of the car and the impact from the wheels. The function of the frame is to support and connect the various assemblies of the car, so that each assembly maintains a relatively correct position, and withstands various loads inside and outside the car. Among them, cross beam processing is an indispensable step in automobile production, and automobile cross beams are usually stamped, which has a fast molding speed and low processing cost.

In the prior art, stamping of automobile cross beams is usually completed by using a stamping machine that cooperates with an upper die set and a lower die set. However, with the increase of processing time, the lower die set of the stamping machine with a long stamping service life will be deformed due to high pressure over the years, resulting in a high maintenance rate of the lower die set. At the same time, the stamped automobile cross beam is easily stuck in the lower die set and difficult to dislodge, and the metal scraps generated in the process of stamping the automobile cross beam cannot be processed. Usually, they are cleaned up collectively after the processing work is completed. However, the metal scraps generated in the production process are easily sunk into the lower die set during the stamping process, accelerating the deformation of the lower die set, reducing the service life of the equipment, and easily leading to a decline in production quality.

A mold assembly, both ends of which are slidably connected to the outer surface of the limit rod, and the mold assembly is used to support the automobile beam to be processed;

A stamping assembly, which is fixedly mounted on the lower surface of the top seat and is used to perform a stamping operation on the automobile cross beam that needs to be stamped;

A cleaning component, the cleaning component is fixedly mounted inside the base, and the cleaning component is used to collect waste chips generated during the stamping process;

A pressure assembly, the pressure assembly is arranged below the mold assembly, and the pressure assembly is used to cooperate with the cleaning assembly to clean up the waste chips generated during the production process;

The mold assembly includes a positioning groove, which is opened on the upper surface of the base. A supporting frame is arranged inside the positioning groove, and the supporting frame is arranged in an arc shape. Both ends of the supporting frame are fixedly connected with mounting plates, and one end of the mounting plate away from the supporting frame is slidably connected to the outer surface of the limiting rod, and the lower surface of the mounting plate is elastically connected to the positioning groove through an elastic telescopic rod.

The mounting plate is symmetrically provided with a slide groove at one end close to the supporting frame, a slider is slidably connected in the slide groove through a spring, a clamping block is fixedly installed on the upper surface of the slider, the upper surface and the lower surface of the clamping block are both arranged in an inclined state, and an electromagnetic is arranged on the clamping block, and the two ends of the automobile cross beam to be stamped are placed on the clamping block, and after the placement is completed, the automobile cross beam is squeezed by the stamping assembly, so that the automobile cross beam exerts pressure on the clamping block under the action of the squeezing force, thereby prompting the clamping block to slide to both sides following the slider under the action of pressure, and finally the two ends of the automobile cross beam pass through the clamping block and contact the upper surface of the mounting plate below, and at the same time, the automobile cross beam is completely stamped. At this time, pressure is applied to the top seat through a pressure device to force the top seat to move downward, and gradually make the stamping assembly close to the block, and finally make the stamping assembly contact with the block, and gradually increase the extrusion force, so that under the action of pressure, the block will follow the mounting plate to move into the positioning groove, and make the lower surface of the mounting plate and the supporting frame fit with the positioning groove. At this time, as the stamping assembly continues to be pressed downward, further pressure will be applied to the block, thereby causing the block to move to both sides, and finally the stamping assembly will contact with the surface of the automobile beam and stamp it. After stamping, the stamping assembly can be moved up to remove the stamping assembly and take out the stamped automobile beam.

Preferably, the stamping assembly includes a stamping block, the upper surface of which is fixedly connected to the lower surface of the top seat, wherein the lower surface of the stamping block can be fitted with the surface of the supporting frame away from the base, and the inside of the stamping block is symmetrically provided with filling grooves, in which a push plate is slidably connected by a spring, and the outer surface of the push plate is fixedly connected to a first scraper, and the first scraper is arranged in an arc shape, wherein the curvature of the first scraper is arranged to be consistent with the curvature of the bottom of the filling groove, the cross-section of the first scraper is arranged in a triangle, and the outer end of the first scraper is initially arranged on the outside of the stamping block, and the first scraper is arranged obliquely.

Preferably, an electromagnet is provided on the lower surface of the punching block, and the electromagnet magnetism on the lower surface of the punching block is set to be opposite to the magnetism of the card block. When the punching assembly moves into the support frame through the card block, the first scrapers on both sides of the punching block will gradually contact the top of the support frame to generate an extrusion force, and the extrusion force gradually increases with the movement of the punching block, so that the first scraper will move into the inside of the punching block together with the pushing plate under the action of pressure, and the first scraper will firmly adhere to the inner surface of the support frame. When the punching operation is completed and the punching block moves upward, because the cross-section of the first scraper is triangular and the first scraper is obliquely arranged, the first scraper will press the inner surface of the support frame. Friction is generated, and when the stamping operation is completed, the lower surface of the stamping block and the clamping block can be energized and magnetized, so that the lower surface of the stamping block adsorbs the automobile beam after the stamping is completed, and moves upward with the upward movement of the stamping block. When the lower surface of the stamping block is close to the clamping block, the clamping block will move to both sides due to the influence of magnetic repulsion, thereby reducing the friction force on the side of the stamping block, and finally break away from the contact with the side of the stamping block, so that the clamping block can fix the automobile beam when stamping is required, and move to both sides after the stamping is completed to facilitate the removal of the automobile beam after the stamping is completed. While improving the fixing effect, it can also avoid the problem of the automobile beam being stuck in the supporting frame and difficult to remove after the stamping.

Preferably, the cleaning component includes a storage cavity, which is symmetrically opened inside both sides of the base, and a through groove is reserved on the surface of the storage cavity close to the locking groove. The storage cavity is connected with the locking groove through the through groove, and the surface of the storage cavity close to the locking groove is rotatably connected to the second scraper, wherein the second scraper is initially set at an angle, and the second scraper is initially set in the storage cavity.

Preferably, the lower surface of the second scraper near one end of the clamping groove is rotatably connected with the first clamping plate, the lower end of the first clamping plate is elastically slidably connected with the second clamping plate, the bottom ends of the second clamping plate are fixedly connected with connecting rods on both sides, the outer end of the connecting rod is rotatably plugged with an adapter frame, wherein the outer end of the connecting rod is also slidably arranged in the adapter block, and the end of the adapter frame away from the connecting rod is fixedly connected with a power plate, and the power plate is elastically slidably connected to the lower surface of the clamping groove of the base, as the supporting frame is squeezed and lowered by the stamping block, the slider will gradually contact the power plate, and then the power plate will be squeezed and moved downward as the slider moves downward. When the power plate moves downward , will drive the adapter frame to move downward, that is, the connecting rod inside it moves downward, and when the connecting rod moves downward, it will drive the second clamping plate and the first clamping plate to move downward, thereby prompting the second scraper to rotate, and finally its end face contacts the outer surface of the supporting frame, and with the process of continuing to move downward, the friction between the second scraper and the outer surface of the supporting frame gradually increases. When the friction between the second scraper and the outer surface of the supporting frame reaches the maximum, at this time, as the supporting frame continues to descend, the second clamping plate will be elastically pulled down on the first clamping plate, and at the same time, the second scraper also maintains the maximum friction with the outer surface of the supporting frame, so that the second scraper scrapes off the metal waste on the outer surface of the supporting frame.

Preferably, the pressure assembly includes a composite groove, which is opened on the middle lower surface of the positioning groove, wherein the groove bodies on both sides of the composite groove are arranged in a stepped shape, and a composite block is elastically inserted in the composite groove, and the lower surfaces at both ends of the composite block can overlap and fit with the groove body surfaces on both sides of the composite groove.

Preferably, a pressure bag is provided in contact with the lower surface of the inner end of the composite block, and the bottom of the pressure bag is fixedly connected to the inner lower surface of the composite groove.

Preferably, an air guide tube is fixedly connected to the lower surface of the pressure bag, and an air pressure groove is connected to the bottom end of the air guide tube. The side of the air pressure groove away from the air guide tube is opened on the edge groove bodies on both sides of the clamping groove, and a filter plate is arranged on the side of the air pressure groove away from the air guide tube, and the filter plate is fixedly installed in the edge groove body of the clamping groove. As the support frame moves downward, the support frame will gradually contact and squeeze the composite block. When the extrusion force applied to the composite block is greater than the elastic force between it and the composite groove, the composite block will be driven to move into the composite groove and squeeze the pressure bag below it. As the pressure bag is squeezed, it will inject the internal air pressure into the air pressure groove through the air guide tube and release it through the filter plate at the outer end of the air pressure groove. As the support frame moves downward, the gap between the support frame and the clamping groove gradually decreases, thereby further enhancing the air pressure released in the air pressure bag, thereby generating a blowing force on the clamping groove.

The present invention provides a crossbeam forming mechanism for automobile manufacturing, which has the following beneficial effects:

1. The crossbeam forming mechanism of the automobile manufacturing can realize that during the process of stamping and forming the automobile crossbeam, the supporting frame and the mounting plate can also be extruded and shaped by setting a mold assembly, so that the shapes of the supporting frame and the mounting plate are always consistent with the positioning groove, thereby achieving that the mold can be kept accurate and intact each time the automobile crossbeam is stamped and formed, so that the stamped automobile crossbeam always meets the precision requirements, avoiding the prior art that the mold group is stamped and deformed as the use time increases, resulting in quality problems in the subsequent production of automobile crossbeams.

2. The crossbeam forming mechanism of the automobile manufacturing makes the first scrapers on both sides of the punching block scrape the inner surface of the supporting frame during the resetting process, so as to prevent the metal scraps generated in the punching process from staying on the inner surface of the supporting frame and eventually stacking up into block-shaped metal scraps over time. Not only will the surface of the automobile crossbeam be unevenly grooved due to the extrusion force during the production process, affecting the quality, but the supporting frame will also be deformed, causing damage to the mold and significantly reducing the production quality.

3. The crossbeam forming mechanism of the automobile manufacturing can fall into the storage cavity through the oblique second scraper to clean the outer surface of the supporting frame, and can also collect and process the waste chips in a centralized manner, which can not only keep the outer surface of the supporting frame clean at all times to improve the protection of the stamping die, but also further improve the quality of the stamped automobile crossbeam, and greatly improve the cleaning efficiency of the equipment itself, saving manpower and material resources.

4. The crossbeam forming mechanism of the automobile manufacturing can achieve the effect of cleaning the metal scraps in the positioning groove, so as to avoid excessive metal scraps remaining in the positioning groove, which may cause the lower surface of the supporting frame to deform as the stamping work proceeds, resulting in quality problems in the extruded automobile crossbeam. In combination with the first scraper and the second scraper, the cleaning effect of the metal scraps is improved to the greatest extent, which greatly protects the supporting frame and also improves the quality of the automobile crossbeam forming.

A pressure assembly 8, which is disposed below the mold assembly 5 and is used to cooperate with the cleaning assembly 7 to clean up waste chips generated during the production process;

The mold assembly 5 includes a positioning groove 51, which is opened on the upper surface of the base 1. A supporting frame 52 is arranged inside the positioning groove 51. The supporting frame 52 is arranged in an arc shape. Both ends of the supporting frame 52 are fixedly connected with mounting plates 53. One end of the mounting plate 53 away from the supporting frame 52 is slidably connected to the outer surface of the limiting rod 2, and the lower surface of the mounting plate 53 is elastically connected to the positioning groove 51 through an elastic telescopic rod.

A clamping block 56 is fixedly installed on the upper surface of the slider 55, and the upper and lower surfaces of the clamping block 56 are both arranged to be inclined, and an electromagnet is arranged on the clamping block 56.

During operation, the two ends of the automobile beam that need to be punched are placed on the clamping block 56, and after the placement is completed, the automobile beam is squeezed by the punching assembly 6, so that the automobile beam exerts pressure on the clamping block 56 under the action of the squeezing force, thereby prompting the clamping block 56 to slide to both sides following the slider 55 under the action of pressure, and finally the two ends of the automobile beam pass through the clamping block 56 and contact the upper surface of the mounting plate 53 below, and the automobile beam is fixed at the same time. At this time, pressure is applied to the top seat 3 through the pressure device, prompting the top seat 3 to move downward, and gradually making the punching assembly 6 close to the clamping block 56, and finally making the punching assembly 6 contact with the clamping block 56, and gradually increasing the squeezing force, so that under the action of pressure, the clamping block 56 will follow the mounting plate 53 to move into the clamping groove 51, and make the lower surface of the mounting plate 53 and the supporting frame 52 fit with the clamping groove 51, at this time, with the punching assembly Continuing to press down the part 6 will cause further pressure on the block 56, thereby causing the block 56 to move to both sides, and finally the stamping component 6 contacts the surface of the automobile beam and performs stamping forming on it. After stamping and forming, the stamping component 6 can be moved up to remove the stamping component 6 and take out the stamped automobile beam. By setting the mold component 5, it can be achieved that in the process of stamping and forming the automobile beam, the supporting frame 52 and the mounting plate 53 can also be extruded and shaped, so that the shapes of the supporting frame 52 and the mounting plate 53 are always consistent with the clamping groove 51, thereby achieving each time the automobile beam is stamped and formed. The mold can be kept accurate and intact, so that the stamped automobile beam always meets the precision requirements, avoiding the prior art that the lower mold group is stamped and deformed with the increase of use time, resulting in quality problems in the subsequent production of automobile beams.

Second embodiment: As shown in Figure 5, the stamping assembly 6 includes a stamping block 61, the upper surface of the stamping block 61 is fixedly connected to the lower surface of the top seat 3, wherein the lower surface of the stamping block 61 can be in contact with the surface of the supporting frame 52 away from the base 1, and the inside of the stamping block 61 is symmetrically provided with a filling groove 62, and a push plate 63 is slidably connected to the filling groove 62 through a spring, and the outer surface of the push plate 63 is fixedly connected to a first scraper 64, and the first scraper 64 is arranged in an arc shape, wherein the curvature of the first scraper 64 is arranged to be consistent with the curvature of the bottom of the filling groove 62, the cross-section of the first scraper 64 is arranged to be triangular, and the outer end of the first scraper 64 is initially arranged on the outside of the stamping block 61, and the first scraper 64 is arranged obliquely.

During operation, when the punching assembly 6 moves into the supporting frame 52 through the clamping block 56, the first scrapers 64 on both sides of the punching block 61 will gradually contact with the top of the supporting frame 52 to generate an extrusion force, and as the punching block 61 moves, the extrusion force gradually increases, so that under the action of pressure, the first scraper 64 will move into the inside of the punching block 61 together with the pushing plate 63, and at the same time, the first scraper 64 is firmly attached to the inner surface of the supporting frame 52. When the punching operation is completed and the punching block 61 moves upward, because the cross-section of the first scraper 64 is triangular and the first scraper 64 is obliquely arranged, the first scraper 64 will generate friction on the inner surface of the supporting frame 52, that is, during the resetting process of the punching block 61, the first scrapers 64 on both sides of the punching block 61 will scrape the inner surface of the supporting frame 52, so as to prevent the metal scraps generated during the punching process from staying on the inner surface of the supporting frame 52 and eventually stacking into block-shaped metal scraps over time.

When the lower surface of the stamping block 61 is close to the clamping block 56, the clamping block 56 will move to both sides due to the influence of magnetic repulsion, thereby reducing the friction force on the side of the stamping block 61, and finally break away from the contact with the side of the stamping block 61, so that the clamping block 56 fixes the automobile beam when stamping is needed, and moves to both sides after the stamping is completed to facilitate the removal of the stamped automobile beam. While improving the fixing effect, it can also avoid the problem of the automobile beam being stuck in the supporting frame 52 and difficult to remove after the stamping.
