Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a self-positioning and self-detaching metal stamping die. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or plastically deform, thereby obtaining the desired parts.

[0003] For example, Chinese Patent Publication No. CN206794547U describes a metal stamping die. This die automatically coats the metal material with drawing oil before stamping, effectively simplifying the stamping process. Simultaneously, during stamping, excess drawing oil is extruded from the metal material and flows back into the receiving groove, preventing waste and reducing residual drawing oil on the metal part. This solution allows for stamping of the metal part while simultaneously coating it with drawing oil.

[0004] However, in the above solution, it is not convenient to automatically unload the formed workpiece after stamping. Users need to manually or with auxiliary tools to remove the material, which poses certain safety hazards and results in low efficiency. Utility Model Content

[0025] Please see Figure 1-4 In this embodiment of the invention, the self-positioning and self-detaching metal stamping die includes a processing table 1. Four support legs 15 are fixedly connected to the bottom of the processing table 1. A stamping table 2 is fixedly connected to the top of the processing table 1. A stamping groove 11 is formed on the top of the stamping table 2, and an installation groove 10 is formed at the bottom of the stamping table 2. A positioning plate 12 is connected to the bottom of the stamping groove 11 via a top-mounting structure. The positioning plate 12 is slidably connected within the installation groove 10. The top of the positioning plate 12 penetrates the side wall of the stamping table 2 and is slidably connected to the stamping table 2. Two limiting plates 9 are fixedly connected to the top of the stamping table 2. Two limiting plates 9 are located on both sides of the stamping groove 11. A pusher cylinder 3 is fixedly connected to the top of the stamping table 2. A pusher plate 8 is fixedly connected to the extended end of the support rod 4. Support rods 4 are fixedly connected to the four corners of the top of the processing table 1. A mounting plate 5 is fixedly connected to the top of the four support rods 4. A stamping cylinder 7 is fixedly connected to the bottom of the mounting plate 5. A stamping head 6 is fixedly connected to the extended end of the stamping cylinder 7. The stamping head 6 is located directly above the stamping groove 11. A feeding plate 13 is fixedly connected to the side wall of the stamping table 2. A collection box 14 is provided at the bottom of one end of the feeding plate 13.

[0026] Please see Figure 1-2 , Figure 4The top-feeding structure includes a top-feeding cylinder 22, which is fixedly connected to the bottom side wall of the mounting groove 10. A top rod 17 is fixedly connected to the extended end of the top-feeding cylinder 22, and a top block 16 is fixedly connected to the top of the top rod 17. The top block 16 penetrates the side wall of the stamping table 2 and extends into the stamping groove 11. The top block 16 is slidably connected to the stamping table 2. A vertical rod 19 is fixedly connected to the bottom of the mounting groove 10, and a rotating rod 20 is rotatably connected to the side wall of the vertical rod 19. Sliding grooves 18 are provided at both ends of the rotating rod 20, and connecting rods 21 are slidably connected within each of the two sliding grooves 18. One end of each connecting rod 21 extends out of a corresponding sliding groove 18. One end of one connecting rod 21 is rotatably connected to the side wall of the positioning plate 12. One end of a connecting rod 21 is rotatably connected to the lower end of the side wall of the push rod 17. By activating the push cylinder 22, the extended end of the push cylinder 22 drives the push rod 17 and the push block 16 to move upward, pushing the workpiece out of the stamping groove 11. At this time, the push block 16 is level with the stamping table 2. When the push rod 17 moves, it will drive the right connecting rod 21 to rotate, causing the right connecting rod 21 to drive the rotating rod 20 to rotate. When the rotating rod 20 rotates, it will drive the positioning plate 12 to move through the left connecting rod 21, causing the positioning plate 12 to move downward, thereby releasing the restriction on the workpiece. Then, by activating the push cylinder 3, the push plate 8 can be driven to push the workpiece to the surface of the unloading plate 13, and finally slide down into the collection box 14 through the unloading plate 13.

[0027] Please see Figure 1-2 , Figure 4 The top block 16 is made of rubber. When the workpiece is ejected from the stamping groove 11, the rubber top block 16 can prevent scratches on the workpiece.

[0028] Please see Figure 1-3 The pusher plate 8 is arc-shaped, which increases the contact area between the pusher plate 8 and the workpiece, thereby improving the stability of the pusher plate 8 when pushing the material.

[0029] Please see Figure 1-3 The sidewalls of both limiting plates 9 are inclined at one end, which increases the distance between the two limiting plates 9 at one end, thus making it easier to place the workpiece between the two limiting plates 9.

[0030] Please see Figure 1-4 The top side wall of the stamping table 2 is inclined, which makes it easy for the workpiece to slide down the inclined side wall onto the surface of the unloading plate 13, and finally slide down the unloading plate 13 into the collection box 14.

[0031] The working principle of this utility model is as follows: When stamping a workpiece is required, the workpiece is placed between two limiting plates 9. The pusher cylinder 3 is activated, and its output end drives the pusher plate 8 to move, causing the pusher plate 8 to press against the workpiece, so that one end of the workpiece abuts against the side wall of the positioning plate 12, thereby positioning the workpiece. Then, the stamping cylinder 7 is activated, and its stamping head 6 stamps the workpiece. After stamping, the ejector cylinder 22 is activated, and its extended end drives the ejector rod 17 and the ejector block 16 to move upward, ejecting the workpiece out of the stamping groove 11. At this time, the ejector block 16 and the stamping table 2... When the top rod 17 moves, it will drive the right connecting rod 21 to rotate, which in turn drives the rotating rod 20 to rotate. When the rotating rod 20 rotates, it will drive the positioning plate 12 to move through the left connecting rod 21, causing the positioning plate 12 to move downward, thereby releasing the limit on the workpiece. Then, the pusher cylinder 3 can be activated to drive the pusher plate 8 to push the workpiece to the surface of the unloading plate 13. Finally, the workpiece slides down into the collection box 14 through the unloading plate 13. Then, the top block 16 and the positioning plate 12 are reset by the top cylinder 22. The pusher cylinder 3 is activated to drive the pusher plate 8 to reset, and the stamping of the next workpiece can begin.
