Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a stacked riveting hardware stamping die. Background Technology

[0002] Stacking and riveting hardware stamping dies are stamping dies used to stack and rivet multiple hardware parts. They are widely used in occasions where multiple metal sheets or components need to be connected together, such as stacking and riveting motor stators and rotors.

[0003] During the use of overlapping riveting hardware stamping dies, the stamping operation involves the shearing and deformation of metal materials, which inevitably produces debris. If the debris is not cleaned up in time, it will accelerate the wear of the die, reduce the overall quality of the product, block the gaps or channels of the die, affect stamping efficiency and precision, and increase the risk of equipment failure.

[0004] Therefore, this utility model proposes a stacked riveting hardware stamping die. Utility Model Content

[0005] The purpose of this invention is to provide a stacked riveting hardware stamping die to solve the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A composite riveting hardware stamping die includes a top die, a magnetic plate movably sleeved on the inner wall of the top die, a limiting ring movably sleeved inside the magnetic plate, the inner wall of the limiting ring being fixedly connected to a stamping column, an extension frame fixedly connected to the front of the top die, and a scraping mechanism provided inside the extension frame, the top end of the scraping mechanism being flush with the bottom end of the top die.

[0008] The top mold has four sets of circular holes inside, arranged in a square quadrangular array. Each circular hole has a movably fitted limit post on its inner wall. The bottom mold is fixedly connected to the bottom end of the limit post. The bottom mold has a slag collection groove inside, and a chip removal mechanism is movably fitted to the inner wall of the slag collection groove.

[0009] Furthermore, the chip scraping mechanism includes a chip scraping bucket, the inside of which is provided with a through groove. The width of the through groove is the same as the diameter of the stamping column. Telescopic grooves are provided on both sides of the through groove. Three sets of springs are fixedly connected to the inner wall of each telescopic groove. The three sets of springs are arranged in a linear array. Telescopic connecting blocks are fixedly connected to the outer wall of each spring. The adjacent surfaces of two sets of telescopic connecting blocks are in contact with each other. An inclined push plate is fixedly connected to the back of each telescopic connecting block.

[0010] Furthermore, the top mold has two sets of sliding grooves inside. One set of sliding grooves is movably fitted with a threaded rod 2. The front of the threaded rod 2 is fixedly connected to the output end of a motor 1. The outer wall of the motor 1 is fixedly connected to an extension frame. The back of the extension frame is fixedly connected to the top mold. The outer wall of the threaded rod 2 is threadedly connected to one set of connecting blocks 1. The other set of connecting blocks 1 is movably fitted with a limiting slide rod. The outer wall of the limiting slide rod is movably fitted with the top mold.

[0011] Furthermore, the scraper hopper is a semi-enclosed hopper shape, with an opening at the top of the back of the scraper hopper. The inner walls of the opening of the scraper hopper are all inclined inwards, and an inclined push plate is attached to the inner wall of the scraper hopper. The side of the inclined push plate is attached to the inner wall of the scraper hopper.

[0012] Furthermore, two sets of protective support plates are fixedly connected to the bottom end of the top mold, and scraper buckets are provided on opposite sides of the two sets of protective support plates.

[0013] Furthermore, the chip removal mechanism includes a second motor, the output end of which is fixedly connected to a threaded rod, the outer wall of which is movably sleeved with the bottom mold, and the outer wall of which is threadedly connected to a second connecting block, the side of which is fixedly connected to a chip pusher block, and the outer wall of which is movably sleeved with the bottom mold.

[0014] Furthermore, the bottom mold has a slot inside, a stamping column is provided at the top of the slot, the bottom of the slot is connected to the slag collection trough, and a collection plate groove is provided on both sides of the slot. A partition plate is movably sleeved on the inner wall of the collection plate groove. The bottom end of the partition plate is conical, and the outer wall of one set of partition plates is in contact with the chip pusher block.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. By setting a magnetic plate at the bottom of the top die, metal debris generated during the stamping operation of the stamping column is adsorbed. After the equipment has been producing continuously for a certain period of time, the motor is started, which drives the scraper bucket to operate and scrape off the metal debris adsorbed on the surface of the magnetic plate. This maintains the magnetic properties of the magnetic plate. With the help of the strong magnetic field generated by the magnet or electromagnet, the debris is immediately adsorbed and fixed on the adsorption plate, preventing the debris from entering the gaps or channels of the die. This avoids the debris from causing scratches, deformation or other damage to the workpiece during the stamping process, improves product quality, extends the service life of the die, and significantly reduces the failure rate of the equipment.

[0017] 2. During the stamping process, the debris generated at the bottom of the sheet metal will fall smoothly into the slag collection trough through the pre-designed slots. Then, the debris accumulated inside the slag collection trough is cleaned by the chip pusher block and pushed out of the internal space of the mold, avoiding the accumulation of debris in the mold and keeping the mold clean at all times. This ensures the smooth operation of stamping production, improves the overall quality of the product, and also extends the service life of the mold. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] Please see Figures 1 to 7 As shown, the stacked riveting hardware stamping die provided by this utility model includes a top die 1, a magnet plate 12 is movably sleeved on the inner wall of the top die 1, a limit ring 13 is movably sleeved inside the magnet plate 12, the inner wall of the limit ring 13 is fixedly connected to the stamping column 11, an extension frame 6 is fixedly connected to the front of the top die 1, a scraping mechanism is provided inside the extension frame 6, and the top end of the scraping mechanism is flush with the bottom end of the top die 1.

[0030] The top mold 1 has four sets of round holes inside, arranged in a square four-corner array. The inner walls of the round holes are movably fitted with limit posts 3. The bottom mold 2 is fixedly connected to the bottom end of the limit posts 3. The bottom mold 2 has a slag collection groove inside, and the inner wall of the slag collection groove is movably fitted with a chip removal mechanism.

[0031] The chip scraping mechanism includes a chip scraper 10. The inside of the chip scraper 10 is provided with a through groove. The width of the through groove is the same as the diameter of the stamping column 11. Telescopic grooves are provided on both sides of the through groove. Three sets of springs 19 are fixedly connected to the inner wall of each telescopic groove. The three sets of springs 19 are arranged in a linear array. Telescopic connecting blocks 18 are fixedly connected to the outer wall of the springs 19. The adjacent surfaces of the two sets of telescopic connecting blocks 18 are in contact with each other. An inclined push plate 20 is fixedly connected to the back of the telescopic connecting block 18.

[0032] The top mold 1 has two sets of sliding grooves inside. One set of sliding grooves is movably fitted with a threaded rod 14. The front of the threaded rod 14 is fixedly connected to the output end of the motor 4. The outer wall of the motor 4 is fixedly connected to the extension frame 6. The back of the extension frame 6 is fixedly connected to the top mold 1. The outer wall of the threaded rod 14 is threadedly connected to one set of connecting blocks 17. The other set of connecting blocks 17 is movably fitted with a limiting slide rod 15. The outer wall of the limiting slide rod 15 is movably fitted with the top mold 1.

[0033] The scraper hopper 10 is a semi-enclosed hopper. The top of the back of the scraper hopper 10 is set as an opening. The inner wall of the opening of the scraper hopper 10 is inclined inward. The inner wall of the scraper hopper 10 is attached to the inclined push plate 20. The side of the inclined push plate 20 is attached to the inner wall of the scraper hopper 10.

[0034] Two sets of protective support plates 16 are fixedly connected to the bottom of the top mold 1, and scraper buckets 10 are provided on opposite sides of the two sets of protective support plates 16.

[0035] During the stamping process, the sheet metal to be stamped is placed on the top of the bottom die 2, and the top die 1 moves downward. Its protruding stamping column 11 performs a stamping operation on the sheet metal. During this process, the generated debris is affected by the magnetic force of the magnetic plate 12 and is attracted to the surface of the magnetic plate 12. After a certain batch of stamping is completed, a certain amount of debris will be attracted to the surface of the magnetic plate 12. At this time, the motor 4 is started, and its output end drives the threaded rod 14 to rotate inside the top die 1, thereby causing the connecting block 17 to slide inside the top die 1 and push the scraper hopper 10 into the lower part of the top die 1. The contact surface between the scraper hopper 10 and the top die 1 is inward. The protruding part of the plate is inclined and scrapes the surface of the magnet plate 12, causing the metal debris adsorbed on the surface of the magnet plate 12 to separate from the magnet plate 12. After losing magnetic attraction, the debris falls into the scraper hopper 10 under the action of gravity and is collected by the scraper hopper 10 for easy cleaning by workers. The magnet plate 12 uses a magnet with weak magnetic force, which can attract small debris, but will not attract heavy plates and parts, thereby achieving instant adsorption of debris and avoiding scratches, deformation or other damage to the workpiece during the stamping process. This improves product quality, extends the service life of the mold, and reduces the equipment failure rate.

[0036] In addition, by setting a protective support plate 16, a certain height gap is maintained between the magnet plate 12 and the sheet material to prevent the magnet plate 12 from directly contacting the sheet material and to avoid the debris adsorbed on the surface of the magnet plate 12 from having an adverse effect on the stamping of the sheet material. At the same time, by adjusting the height of the protective support plate 16, the stamping depth of the stamping column 11 on the sheet material can be precisely controlled to ensure the accuracy and consistency of the stamping process.

[0037] Example 2

[0038] Based on Example 1, please refer to Figure 1 , 2 As shown in Figures 3 and 7, the chip removal mechanism includes a second motor 5. The output end of the second motor 5 is fixedly connected to a threaded rod 9. The outer wall of the threaded rod 9 is movably sleeved with the bottom mold 2. The outer wall of the threaded rod 9 is threadedly connected to a connecting block 21. The side of the connecting block 21 is fixedly connected to a chip pusher block 8. The outer wall of the chip pusher block 8 is movably sleeved with the bottom mold 2.

[0039] The bottom mold 2 has a slot inside, and a stamping column 11 is set at the top of the slot. The bottom of the slot is connected to the slag collection trough. A collection plate groove is set on both sides of the slot. A partition plate 7 is movably sleeved on the inner wall of the collection plate groove. The bottom of the partition plate 7 is conical. The outer wall of one set of partition plates 7 is in contact with the chip pusher block 8.

[0040] When debris is generated at the lower end of the plate, due to its position, the upper magnetic plate 12 cannot effectively attract it. At this time, the debris will fall into the slag collection tank through the pre-set slots inside the bottom mold 2. While cleaning the debris attracted to the surface of the magnetic plate 12, the second motor 5 is started, and its output end drives the threaded rod 9 to rotate inside the bottom mold 2. With the rotational power of the threaded rod 9, the chip pusher 8 is driven to slide along a predetermined track inside the bottom mold 2 through the connecting block 21.

[0041] When the chip pusher block 8 slides to the side of the partition plate 7, its front end fits tightly against the slope at the bottom of the partition plate 7. As the chip pusher block 8 continues to move, the slope design causes the partition plate 7 to be gradually pushed upward along the interior of the bottom mold 2. At the same time, during the movement, the chip pusher block 8 can effectively push the debris accumulated in the slag collection trough away from the interior space of the bottom mold 2, thereby achieving efficient cleaning of the debris inside the bottom mold 2, ensuring that the mold is always kept clean, and providing a good working environment for subsequent stamping operations.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
