Technical Field

[0001] The utility model relates to the technical field of waste discharging of stamping dies, in particular to a waste discharging structure for an automatic punching press stamping die. Background Art

[0002] A numerical control punching press is short for a numerically controlled punching press, which is an automated machine tool equipped with a program control system. This control system can logically process a program with control codes or other symbolic instructions, and decode it, so that the punching press can act and process parts. A stamping die is a special process equipment that processes materials into parts in cold stamping processing, and is called a cold stamping die.

[0003] However, the existing method of waste discharging of stamping dies is manually cleaned by workers, such as manual collection, manual scraping, etc. The disadvantage of a large amount of manual participation is that physical strength declines after long-term work, and the waste discharging efficiency also decreases accordingly. It is time-consuming and laborious, and the efficiency is unstable and needs to be improved. In view of the above problems, the inventor proposes a waste discharging structure for an automatic punching press stamping die to solve the above problems. Content of the Utility Model

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Embodiment: As Figures 1-3 shown, the present invention provides a technical solution: an automatic punching die waste discharging structure, including a base 1. Symmetrically distributed punching cylinders 11 are fixedly installed at the top end of the base 1. An upper connecting plate 12 is fixedly installed at the top end of the punching cylinder 11. An upper die 13 is fixedly installed at the bottom end of the upper connecting plate 12. A lower die 14 is fixedly installed at the top end of the base 1. A magnetic frame 15 is arranged outside the lower die 14. The bottom end of the magnetic frame 15 is fixedly connected to the base 1. Symmetrically distributed clamping grooves 16 are opened at the top end of the base 1. Symmetrically distributed connecting pieces 17 are fixedly installed on the inner bottom surface of the clamping grooves 16. One end of the connecting piece 17 is fixedly installed with a first spring 18. A pushing frame 19 is slidably installed inside the magnetic frame 15. The inner wall of the pushing frame 19 is attached to the outer surface of the lower die 14. The top end of the first spring 18 is fixedly connected to the pushing frame 19. Symmetrically distributed moving plates 21 are arranged below the upper connecting plate 12. A scraper 20 is fixedly connected to the bottom end of the moving plate 21. One end of the scraper 20 is attached to the top surface of the magnetic frame 15. A discharging cylinder 22 is fixedly installed at one end of the upper connecting plate 12. The moving plate 21 on the left side is fixedly connected to the driving end of the discharging cylinder 22.

[0019] By adopting the above technical solution, during the process of scraping the metal waste by the scraper 20 with a magnetic attraction effect, the waste will not fall into the lower die 14.

[0020] Symmetrically distributed second springs 23 are fixedly installed outside the magnetic frame 15. One end of the second spring 23 is fixedly connected to a T-shaped plate 24. Symmetrically distributed insertion openings 25 are opened outside the magnetic frame 15. One end of the T-shaped plate 24 slidably penetrates through the insertion opening 25. One end of the T-shaped plate 24 contacts the pushing frame 19.

[0021] By adopting the above technical solution, by arranging the T-shaped plate 24 inserted in the insertion opening 25 and contacting the pushing frame 19 and cooperating with the second spring 23, the pushing frame 19 is restricted. After the T-shaped plate 24 is pulled out, the pushing frame 19 moves under the action of the first spring 18. Thus, the pushing frame 19 can be conveniently controlled by the cooperation of the T-shaped plate 24 and the second spring 23.

[0022] Symmetrically distributed limiting grooves 27 are fixedly installed at the top end of the pushing frame 19. Symmetrically distributed limiting blocks 26 are opened inside the magnetic frame 15.

[0023] By adopting the above technical solution, the limiting block 26 is arranged to facilitate connection with the limiting groove 27, thereby limiting the pushing frame 19 to prevent excessive movement of the pushing frame 19.

[0024] Symmetrically distributed fixing blocks 28 are fixedly installed on the bottom surface of the upper connecting plate 12. Fixing columns 29 are fixedly clamped at opposite ends of the fixing blocks 28. One end of the moving plate 21 on the right side is slidably sleeved outside the fixing column 29.

[0025] By adopting the above technical solution, the moving plate 21 slides on the fixing column 29 to make the control process of the scraping knife 20 by the discharging air cylinder 22 more stable.

[0026] Symmetrically distributed fixing frames 30 are fixedly installed on the outside of the upper connecting plate 12. The bottom ends of the fixing frames 30 are fixedly connected with lighting lamps 31.

[0027] By adopting the above technical solution, the lighting lamp 31 is powered by an external power supply. By setting the lighting lamp 31, the lighting effect is improved, which is convenient for clearly observing the stamping process.

[0028] Foot pads 32 are fixedly installed at the four corners of the bottom surface of the base 1.

[0029] By adopting the above technical solution, by setting the foot pads 32, the contact area between the base 1 and the ground is increased, and the stability is improved.

[0030] Working principle: First, place the material in the lower die 14. Then, control the stamping cylinder 11 to move the upper connecting plate 12 to drive the upper die 13 to contact the lower die 14 for stamping processing. Substances such as metal scraps overflowing during the stamping process are adsorbed on the inner wall by the magnetic force frame 15. When it is necessary to clean and remove the waste, pull out the T-shaped plate 24 from the socket 25, and the second spring 23 is in a stretched state. Then, rely on the first spring 18 on the connecting piece 17 in the card slot 16 to push up the pushing frame 19. The surface of the pushing frame 19 and the lower die 14 fits with the inner wall of the magnetic force frame 15. Thus, the metal debris materials are concentrated and pushed out during this process. Then, control the discharging air cylinder 22 to push the moving plate 21 to drive the discharging air cylinder 22 to scrape the pushed waste. Thus, the waste discharging operation is realized. The structure is convenient to operate, greatly reduces the participation of labor, and is more efficient and practical.

[0031] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these changes and modifications.
