Description

Technical Field

[0001] The invention relates to the technical field of stamping processing, in particular to a multi-stage stamping processing forming equipment and a stamping processing method for an automobile cross beam. Background Art

[0002] Stamping is a production technology that uses the power of conventional or special stamping equipment to directly subject sheet metal to deformation force in the mold and deform it, thereby obtaining product parts with certain shapes, sizes and performances. It is a metal cold deformation processing method, so it is called cold stamping or sheet metal stamping, or stamping for short. The so-called multi-stage stamping generally refers to the work of gradual stamping at different heights according to a preset process. When making parts such as automobile beams, stamping equipment is needed for shaping.

[0003] The Chinese patent application with the publication number CN216297617U proposes a stamping device for processing automobile cross beams that is easy to demould, including a base, a positioning plate fixedly arranged on the upper end surface of the base, convex plates fixedly connected on both sides of the upper end surface of the positioning plate, rod holes fixedly opened at the middle position of the front end surfaces of the two convex plates, shaft holes fixedly opened on both sides of the middle of the positioning plate, fixed grooves fixedly opened on both sides of the middle of the inner end of the base, cylinders fixedly arranged in the two fixed grooves, double-threaded screws rotatably sleeved in the two rod holes, and fixed plates fixedly sleeved on the outer walls of the middle of the two double-threaded screws. The structure is simple and easy to operate.

[0059] Another technical problem to be solved by the present invention is to provide a stamping method for an automobile cross beam, using a multi-stage stamping forming device, comprising the following steps:

[0060] S1. Board transmission

[0061] The plates required for the beam stamping process are arranged and placed on the electric conveyor belt 2 for conveying. After being conveyed to the discharge end, the extension plate 692 can be controlled to move to insert one end of the plate into it, and then the plate is clamped by the second clamping plate 694 and placed on the fixed mold assembly 8 to achieve the purpose of loading;

[0062] S2. Stamping

[0063] The first cylinder 72 controls the movable die assembly 73 to press the plate downward onto the fixed die assembly 8, and then controls the punch block 77 to move upward to lift up and perform punching and forming processing on the plate;

[0064] S3, unloading after molding

[0065] When the stamping and forming process of the plate is completed, the moving plate 66 is controlled to move to the top of the workpiece, and the two first clamping plates 68 are controlled to clamp and pick up the formed workpiece, and then the workpiece is placed in the corresponding storage position or on the conveying device equipped for processing, so as to perform the unloading operation;

[0066] S4. Debris cleaning

[0067] When all processing steps are completed, the fan 688 can blow away the debris that may be generated during the molding process, so as to achieve the purpose of cleaning and avoid the existence of debris affecting subsequent processing.

[0068] In the actual operation process, firstly, the device is connected to the power supply, and the plates required for the beam stamping processing are arranged and placed on the electric conveyor belt 2 for transportation. After being transported to the discharge end and the plates are extended to a sufficient clamping length, they can be clamped. When the plates are tilted due to the shift in the center of gravity after extending to a longer length, the pressure strip 4 can limit the height of the sides of the plates to prevent them from falling due to excessive tilt angles. After the second electric push rod 697 works, it pushes the movable block 5, and the movable block 5 drives the L-shaped plate 61 to move. It can be seen from the above connection relationship that the overall position of the movable plate 66 can be adjusted to adjust the clamping position of the feeding. After the first motor 696 works, it drives The threaded rod 695 rotates, the threaded rod 695 drives the lifting plate 62 to move up and down, the lifting plate 62 drives the rotating platform 63 to move, and the rotating platform 63 drives the mounting plate 64 to move. It can be seen from the above connection relationship that the clamping height can be adjusted in this way. After the second motor 681 works, it drives the second gear 682 to rotate, the second gear 682 drives the first gear 699 to rotate, and the first gear 699 drives the rotating platform 63 to rotate, so that the clamping direction can be adjusted. After the third electric push rod 683 works, it can push and pull the moving plate 66 to adjust the distance that the moving plate 66 extends out of the outside of the main plate 65, so that the moving plate 66 can be moved and adjusted when facing different directions.

[0069] When loading is required, the extension plate 692 is controlled to move to the inner side of the extension plate 692 through the above control steps, and the first electric push rod 693 pushes the second clamping plate 694, prompting the second clamping plate 694 to tightly squeeze the plate inside the second clamping plate 694. After the clamping condition is formed, the clamped plate is placed on the fixed mold assembly 8, and the extension plate 692 is controlled to move to one side of the box body 3. The first cylinder 72 pushes the movable mold assembly 73 downward to press the plate on the fixed mold assembly 8, and the second cylinder 78 pushes the stamping block 77 upward, and the stamping block 77 moves and performs stamping and forming processing on the plate;

[0070] After the stamping process is completed, the movable mold assembly 73 is controlled to move upward, and then the above adjustment steps are repeated to control the movable plate 66 to move above the stamped workpiece. The fourth electric push rod 685 pushes the control plate 69. After the control plate 69 moves, it drives the push-pull plate 691 to flip. During the flipping process of the push-pull plate 691, the two first clamping plates 68 can be pushed to cause the two first clamping plates 68 to move toward or away from each other. When the first clamping plates 68 move toward each other, the workpiece can be clamped. When they move away from each other, the workpiece can be dropped. After the workpiece is clamped, it is placed in the corresponding storage position or on the conveying device equipped for processing, so as to perform the unloading operation;

[0071] When the movable mold assembly 73 is moved downward to close the fixed mold assembly 8, the guide plate 791 is squeezed and moved downward. When the movable mold assembly 73 is separated from the fixed mold assembly 8, due to the elastic force of the spring 793, the guide plate 791 moves upward again to be higher than the box body 3. When it is necessary to clean the debris that may be generated by the stamping work, the fan 688 works and blows the top of the box body 3. Due to the guiding effect of the guide plate 791, the debris can be blown off in the same direction, so as to achieve the purpose of centralized collection. In addition, during the cleaning process, in order to improve the cleaning effect, After the fifth electric push rod 674 starts working, it can push and pull the strip plate 672 back and forth, and the strip plate 672 drives the rack 675 to move. After the rack 675 moves, it drives the third gear 673 to rotate. The third gear 673 drives the connected rotating rod 671 to rotate, and the rotating rod 671 drives the fan 688 to shake repeatedly. During the shaking process, the fan 688 can blow away the debris in different areas, and fall to the discharge end under the action of the guide plate 791, effectively avoiding the situation where the cleaning of the debris is troublesome and the cleaning is not timely enough, which may affect the subsequent work.

[0072] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
