Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, specifically to an oblique stamping die for automotive parts. Background Technology

[0002] In the rapid development of the automotive manufacturing industry, the processing precision and production efficiency of automotive parts have received increasing attention. Automotive parts often have complex structures, and to meet their specific functional and assembly requirements, operations such as drilling and trimming are frequently required during processing. For parts with inclined angles or special curved surfaces, using oblique stamping dies has become a common and effective method. This oblique stamping method can adapt to the complex shapes of parts, ensure the accuracy of processing positions, and thus ensure that the quality of the parts meets design standards.

[0003] However, when the mold performs operations such as punching and trimming on automotive parts, the scrap material punched off is difficult to expel smoothly from the mold cavity due to the inclination of the stamping direction and the limitations of the mold's own structure. It often remains on the working surface or in the gaps of the mold. As the stamping operation continues, this residual scrap material accumulates, affecting the stamping quality. Therefore, operators have to periodically stop the stamping operation to manually clean the accumulated scrap material from the mold. This process not only interrupts the normal production flow, consuming a significant amount of manpower and time, but also significantly reduces overall production efficiency, hindering large-scale mass production.

[0004] To avoid excessive waste accumulation on the die during the stamping process, ensure product quality, reduce the number of times operators need to clean up waste, and improve production efficiency, we propose an oblique stamping die for automotive parts. Utility Model Content

This effectively collects the waste material generated during the stamping process, preventing a large accumulation of waste material on the die and ensuring product quality. After a certain period of use, the operator can simply pull out the collection box to clean up the waste material, which is convenient and quick. Attached Figure Description

[0025] 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.

[0026] Please see Figure 1-6 This utility model provides a technical solution: an oblique stamping die for automotive parts, including a base plate 1, a lower die base 9 fixedly connected to the top of the base plate 1, a number of positioning blocks provided on the top of the lower die base 9, a number of mounting platforms 8 fixedly connected to the top of the base plate 1, a stamping block 19 slidably mounted on the mounting platform 8, a punching rod 23 fixedly connected to the side of the stamping block 19 near the lower die base 9, a moving component for moving the stamping block 19 is installed on the base plate 1, and a collecting component for collecting stamping waste is installed on the base plate 1;

[0027] The collection component includes a collection box 10, which is slidably installed in the inner cavity of the lower mold base 9. The lower mold base 9 has several sets of discharge channels 33, which correspond to the punching rod 23. Several sets of side plates 18 are fixedly connected to the side wall of the lower mold base 9. Several sets of vibrating plates 32 are provided on the side plates 18. A vibration mechanism that drives the vibrating plates 32 to vibrate is installed on the mounting platform 8.

[0028] In use, the part to be processed is placed on the upper surface of the lower die base 9. The position of the part is initially fixed by the positioning block. Then, the moving component drives the stamping block 19 to move, which moves the punching rod 23 closer to the lower die base 9. The punching operation of the part is completed by the punching of the punching rod 23. The waste generated by punching falls into the collection box 10 along the discharge channel 33. The diameter of the discharge channel 33 is set to be slightly larger than the diameter of the punching rod 23 to ensure that the waste can pass smoothly. During the stamping process, the vibration mechanism drives the vibrating plate 32 to vibrate, which causes the lower die base 9 to vibrate slightly. This further promotes the rapid movement of the waste in the discharge channel 33 and prevents the waste from getting stuck in the discharge channel 33. This effectively collects the waste generated during the stamping process, avoids a large accumulation of waste on the mold, and ensures product quality. After a certain period of use, the operator can pull out the collection box 10 to clean the waste. Compared with the traditional method of cleaning the entire mold surface, this reduces the number of cleaning times and cleaning time, and improves production efficiency.

[0029] The vibration mechanism includes several sets of sliding plates 26. The sliding plates 26 are slidably connected to the inner wall of the mounting platform 8. The top of the sliding plate 26 is fixedly connected to the insert block 27. The stamping block 19 has a slot that matches the insert block 27. The insert block 27 is slidably connected to the slot. The bottom of the sliding plate 26 is detachably installed with an elastic plate 25, which matches the vibrating plate 32.

[0030] The moving component drives the stamping block 19 to move, the insert block 27 drives the sliding plate 26 to move, and the elastic sheet 25 to move. During the movement of the elastic sheet 25, it is blocked by the vibrating plate 32, causing the elastic sheet 25 to deform and reset multiple times. During this process, the elastic sheet 25 strikes the vibrating plate 32, causing the vibrating plate 32 to vibrate.

[0031] The moving component includes several sets of support rods 2. A top plate 4 is fixedly connected to the top of the support rods 2. A cylinder 5 is fixedly installed on the top of the top plate 4. A lifting plate 3 is fixedly connected to the output end of the cylinder 5. The lifting plate 3 is slidably sleeved on the support rods 2. A connecting plate 6 is fixedly installed at the bottom of the lifting plate 3. Several sets of lifting blocks 12 are fixedly connected to the bottom of the connecting plate 6. A first inclined surface is provided on the lifting block 12. A second inclined surface matching the first inclined surface is provided on the stamping block 19. A reset mechanism for driving the stamping block 19 to reset is installed on the bottom plate 1.

[0032] During stamping, the control cylinder 5 drives the lifting plate 3 to descend, which in turn drives the connecting plate 6 to descend. This causes the lifting block 12 to descend. The first inclined surface on the lifting block 12 and the second inclined surface on the stamping block 19 work together to move the stamping block 19 toward the lower die base 9. After stamping is completed, the cylinder 5 drives the lifting block 12 to rise. Under the action of the reset mechanism, the stamping block 19 returns to its original position.

[0033] The reset mechanism includes several sets of mounting plates 7, which are fixedly connected to the top of the base plate 1. Several sets of connecting posts 13 are slidably passed through the mounting plates 7. A limit plate 20 is fixedly connected to one end of the connecting post 13 near the mounting platform 8. The side of the limit plate 20 near the mounting platform 8 is fixedly connected to the sliding plate 26. A reset spring 14 is provided between the connecting post 13 and the mounting plate 7.

[0034] The sliding plate 26 moves, causing the limiting plate 20 and the connecting column 13 to move, which compresses the return spring 14. After the stamping is completed, the lifting block 12 rises and disengages from the stamping block 19. The limiting plate 20 is reset under the elastic force of the return spring 14, which drives the sliding plate 26, the insert block 27 and the stamping block 19 back to their original positions.

[0035] Several sets of mounting rods 29 are fixedly connected to the lifting block 12. A connecting block 28 is fixedly connected to the side of the mounting rod 29 near the lifting block 12. Several sets of movable slots 30 opposite to the connecting block 28 are opened on the stamping block 19. The connecting block 28 is movably connected to the movable slot 30.

[0036] When the lifting block 12 descends and drives the stamping block 19 to move, the connecting block 28 slides on the movable groove 30. When the lifting block 12 rises, the connecting block 28 and the movable groove 30 can drive the stamping block 19 to move away from the lower die base 9, thereby avoiding the problem that the punching rod 23 is stuck on the accessory and cannot be pulled out by the elastic force of the return spring 14.

[0037] A connecting cover 15 is fixedly connected to the bottom of the connecting plate 6. A sliding cover 16 is slidably sleeved on the outside of the connecting cover 15. A limiting pressure plate 34 is fixedly connected to the bottom of the sliding cover 16. A first limiting spring 11 is fixedly connected to the top of the limiting pressure plate 34. The top of the first limiting spring 11 is fixedly connected to the bottom of the connecting plate 6. The connecting cover 15 is sleeved on the outside of the first limiting spring 11. Several sets of sliding columns 17 are slidably installed on the connecting plate 6. The bottom of the sliding column 17 is fixedly connected to the top of the limiting pressure plate 34.

[0038] During the stamping process, the limiting pressure plate 34 first contacts the upper surface of the part. As the connecting plate 6 continues to descend, the limiting pressure plate 34 is pressed tightly against the surface of the part under the action of the first limiting spring 11 to prevent the part from shifting during the stamping process.

[0039] A mounting cover 21 is fixedly connected to the side of the stamping block 19 near the lower die base 9. A limiting block 22 is slidably connected to the inner wall of the mounting cover 21. The limiting block 22 is slidably sleeved outside the punching rod 23. A second limiting spring 24 is fixedly connected to the side of the limiting block 22 near the stamping block 19. The end of the second limiting spring 24 away from the limiting block 22 is fixedly connected to the stamping block 19.

[0040] During stamping, under the action of the second limiting spring 24, the limiting block 22 presses tightly against the surface of the part, further fixing the position of the part, and can also reduce the deformation around the punching hole to a certain extent.

[0041] Two sets of guide blocks 31 are fixedly connected to the inner wall of the collection box 10, and the guide blocks 31 are provided with inclined guide surfaces. The inclined guide surfaces can cause the waste falling into the collection box 10 to converge to the center position, preventing the waste from accumulating below the discharge channel 33 and affecting subsequent collection.

[0042] Working principle: In use, the part to be processed is placed on the upper surface of the lower die base 9. The position of the part is initially fixed by the positioning block. Then, the control cylinder 5 drives the lifting plate 3 to descend, which in turn drives the connecting plate 6 to descend. The lifting block 12 then descends. The first inclined surface on the lifting block 12 cooperates with the second inclined surface on the stamping block 19 to move the stamping block 19 closer to the lower die base 9. This moves the punching rod 23 closer to the lower die base 9. The punching operation of the part is completed by the punching of the punching rod 23. The waste generated by punching falls into the collection box 10 along the discharge channel 33. The diameter of the discharge channel 33 is set to be slightly larger than the diameter of the punching rod 23 to ensure that the waste can pass smoothly. At the same time, the stamping block 19 drives the sliding plate through the insert block 27. The movement of slide plate 26 causes the elastic plate 25 to move. During the movement of elastic plate 25, it is blocked by vibrating plate 32, causing elastic plate 25 to deform and reset multiple times. During this process, elastic plate 25 strikes vibrating plate 32, causing vibrating plate 32 to vibrate, which causes slight vibration of the lower die base 9 as a whole. This further promotes the rapid movement of waste material in the discharge channel 33, preventing waste material from getting stuck in the discharge channel 33. This effectively collects waste material generated during the stamping process, preventing a large amount of waste material from accumulating on the die and ensuring product quality. After a certain period of use, the operator can pull out the collection box 10 to clean the waste material. Compared with the traditional method of cleaning the entire die surface, this reduces the number of cleaning times and cleaning time, and improves production efficiency. The movement of slide plate 26 also causes the limit plate 20 and connecting column 13 to move, causing the return spring 14 to be compressed. After stamping is completed, the lifting block 12 is raised by cylinder 5 and disengaged from the stamping block 19. The limit plate 20 is reset under the elastic force of the return spring 14, causing slide plate 26, insert block 27 and stamping block 19 to return to their original positions. When the lifting block 12 descends, causing the stamping block 19 to move, the connecting block 28 slides on the movable groove 30. When the lifting block 12 rises, the connecting block 28 and the movable groove 30 work together to move the stamping block 19 away from the lower die base 9, thus preventing the punch rod 23 from getting stuck on the part and being unable to be pulled out by the spring force of the return spring 14. During the stamping process, the limiting pressure plate 34 first contacts the upper surface of the part. As the connecting plate 6 continues to descend, the limiting pressure plate 34 presses tightly against the surface of the part under the action of the first limiting spring 11, preventing the part from shifting during the stamping process. During stamping, the limiting pressure block 22 presses tightly against the surface of the part under the action of the second limiting spring 24, further fixing the position of the part.
