Abstract
Description
Technical Field
[0001] This utility model relates to the field of stamping equipment technology, specifically to a stamping forming equipment for aluminum alloy sheet metal parts. Background Technology
[0002] Stamping refers to the process of forming workpieces of the required shape and size by applying external force to sheet metal, pipes, and profiles using a press and dies, causing them to undergo plastic deformation or separation. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and strips. Stamping dies are a processing method that involves placing metal or non-metal materials into a die and then applying external force to cause the materials to undergo plastic deformation or separation, thereby obtaining workpieces of the required shape and size. In industrial manufacturing, many complex parts need to be produced through precise stamping.
[0003] Traditional stamping dies are usually designed as a single unit. The upper die presses down and fits against the lower die to complete the stamping process. This operation is convenient and quick. However, when the pressure block presses down and contacts the sheet metal part, it can cause the sheet metal part to wobble, resulting in the sheet metal part shifting and reducing the quality of the stamped part.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0020] Example:
[0021] Please see Figures 1-3 This utility model provides a technical solution:
[0022] A stamping forming equipment for aluminum alloy sheet metal parts includes a machine body 1. A connecting platform 2 is fixedly connected to the bottom of the inner side of the machine body 1, and a fixed frame 3 is fixedly connected to the top of the inner side of the machine body 1. An electric telescopic rod is fixedly connected inside the fixed frame 3, extending to the outside of the fixed frame 3. A drive platform is fixedly connected to the output end of the electric telescopic rod, and a stamping head 4 is fixedly connected to the bottom of the drive platform. An operating platform 5 is fixedly connected to the top of the connecting platform 2, and a mold cylinder 6 is fixedly connected to the middle of the top of the operating platform 5. Positioning components 7 are symmetrically installed on the top of the operating platform 5. The positioning components 7 are used for positioning and clamping the sheet metal parts during stamping. The positioning components 7 include a stabilizing plate 701, a sliding rod 702, a pressing plate 703, a spring 704, and a roller 705. The stabilizing plate 701 is fixedly connected to the top of the operating platform 5, and the sliding rod 702 is slidably connected to the stabilizing plate 701. Inside 01, the extrusion plate 703 is fixedly connected to the end of the slide rod 702 away from the stabilizing plate 701. The spring 704 is sleeved on the outside of the slide rod 702. The roller 705 is symmetrically rotated and connected to the bottom of the outside of the extrusion plate 703. The operator holds two sets of slide rods 702 and moves them in two opposite directions, so that the slide rods 702 slide inside the stabilizing plate 701, so that one end of the spring 704 follows the extension of the slide rod 702, and then the extrusion plate 703 moves in the opposite direction. Therefore, the roller 705 moves with it. The extrusion plate 703 clamps the part, and the spring 704 begins to rebound, moving closer to the center and fixing the part. After the stamping is completed, the extrusion plates 703 move away from each other outside the part, so that the distance between the extrusion plates 703 is extended, the fixing of the part is released, and the part is pulled out from the mold cylinder 6 to complete the replacement.
[0023] Furthermore, in this embodiment, a limiting ring 706 is fixedly connected to one end of the slide rod 702 near the stabilizing plate 701. A reinforcing plate 707 is fixedly connected to the outside of the stabilizing plate 701. The surface of the extrusion plate 703 is coated with an anti-slip pad 709. Both sides of the spring 704 are rotatably connected with washers 708. When the slide rod 702 slides, the limiting ring 706 is fixedly connected to the slide rod 702 and slides with it. The limiting ring 706 prevents the slide rod 702 from flying out of the stabilizing plate 701 during the movement. The reinforcing plate 707 increases the compressive strength of the stabilizing plate 701, thereby extending its service life. The spring 704 moves between the washers 708 to extend and retract, thereby causing the extrusion plate 703 to move to both ends to clamp the parts.
[0024] Furthermore, in this embodiment, the stabilizing plate 701 has an L-shaped structure design, and the top of the stabilizing plate 701 is threaded with a bolt 710. The stabilizing plate 701 is fixedly connected to the operating table 5 by the bolt 710. The bolt 710 effectively prevents the stabilizing plate 701 from flying off during clamping movement. When the stabilizing plate 701 is damaged, the bolt 710 on the stabilizing plate 701 can be removed using auxiliary tools to replace the stabilizing plate 701, avoiding angular displacement that would cause the sheet metal parts to shift synchronously, thereby resulting in huge errors during stamping.
[0025] Furthermore, in this embodiment, the top of the connecting platform 2 is fixedly connected to the mounting ear 8, and the inside of the mounting ear 8 is rotatably connected to the driven rod 9. One end of the bottom of the driving platform is rotatably connected to the swing rod 10. The driven rod 9 and the swing rod 10 are designed in a cross structure. The connection between the driven rod 9 and the swing rod 10 is a rotatable connection. When the stamping head 4 finishes its work and performs the next stamping operation, the driving platform descends and applies pressure to the swing rod 10, causing the swing rod 10 to tilt. Subsequently, the driven rod 9 and the swing rod 10 approach each other and gradually become parallel.
[0026] Furthermore, in this embodiment, the driven rod 9 is rotatably connected to a linkage rod 11 at the end away from the mounting ear 8, and the swing rod 10 is rotatably connected to a synchronizing rod 12 at the end away from the drive table. A positioning post is rotatably connected at the connection between the linkage rod 11 and the synchronizing rod 12. A crossbar 13 is fixedly connected to the outside of the positioning post, and a receiving hopper 14 is fixedly connected to the outside of the crossbar 13. The inner side of the receiving hopper 14 has an inclined structure design. When the driven rod 9 and the swing rod 10 approach each other and gradually tend to be parallel, the linkage rod 11 and the synchronizing rod 12 approach each other, thereby extending the distance and allowing the receiving hopper 14 to extend outward, thus completing the discharge of waste generated during the stamping of the stamping head 4 and the sheet metal parts.
[0027] In this embodiment, the specific implementation scenario is as follows: When aluminum alloy sheet metal parts need to be stamped, the sheet metal parts are placed on top of the mold cylinder 6, and the telescopic rod drives the stamping head 4 to press down. When sheet metal parts of different sizes need to be stamped, the operator holds two sets of sliding rods 702 and moves them in two opposite directions, so that the sliding rods 702 slide inside the stabilizing plate 701, so that one end of the spring 704 is stretched along with the sliding rods 702, and then the extrusion plate 703 is translated in the opposite direction. Therefore, the roller 705 moves with it, the extrusion plate 703 clamps the part, and the spring 704 begins to rebound. The stamping head 4 moves closer to the center and fixes the part. After each work, when the stamping head 4 is raised, it will generate negative pressure with the inside of the stamped sheet metal part, which will carry out the waste generated after stamping. When the stamping head 4 finishes its work and the next stamping work is carried out, the drive table will descend and apply pressure to the swing rod 10, so that the swing rod 10 will tilt. Then the driven rod 9 and the swing rod 10 will move closer to each other and gradually become parallel, so that the linkage rod 11 and the synchronization rod 12 will move closer to each other, thereby extending the distance and extending the receiving hopper 14 outward, so as to discharge the waste generated during the stamping of the stamping head 4 and the sheet metal part.
[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
