Technical Field

[0001] The present invention relates to the technical field of stamping for auto parts, and more specifically, the present invention relates to a stamping device for a positioning ring of auto parts. Background Art

[0002] The positioning ring is installed between the vehicle steering shaft and the lock catch to lock the steering shaft within the lock catch, increasing the force required to turn the steering wheel when the steering wheel is locked, thus playing an anti-theft role. In the past, when producing the positioning ring, first, a punching and stamping was performed on a metal sheet by a punching press, and then the product was manually removed from the punching press. The metal sheet is placed in a groove on the workbench, because the groove can prevent the metal sheet from shifting or deforming. However, after stamping, the product needs to be demolded. Since the metal sheet is relatively thin, it is impossible to set up a ejector rod structure similar to an ejector at the bottom of the mold to extrude the product from the groove, resulting in a relatively low overall processing efficiency. Summary of the Invention

[0003] To achieve the above object, the present invention provides the following technical solution: A stamping device for a positioning ring of auto parts, including a punching press body and a workbench located below the punching press body. The positioning ring is placed on the surface of the workbench.

Specific implementation manner

[0019] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0020] As Figures 1-4 A stamping device for the positioning ring 22 of automobile parts shown in the figure includes a punching machine body 1 and a workbench 2 located below the punching machine body 1. The positioning ring 22 is placed on the surface of the workbench 2. A lifting punch 3 is installed at the bottom end of the punching machine body 1, and a die 4 is installed in the middle of the bottom surface of the punch 3. A pressing ring 5 extending downward in a circle is installed at the edge of the bottom end of the punch 3. A lifting placement ring 6 is provided at the edge of the positioning ring 22 for limiting the placement of the positioning ring 22. A lifting member for driving the placement ring 6 to lift is provided inside the workbench 2. During the lifting movement of the punch 3, the placement ring 6 is driven to lift. A blanking assembly for pushing the positioning ring 22 off the workbench 2 after the placement ring 6 descends is provided on one side of the workbench 2, and a clamping member for limiting the movement of the lifting member and the placement ring 6 is provided on the other side of the workbench 2.

[0021] On the above basis, during work, the product to be punched and stamped is placed inside the placement ring 6 on the workbench 2, and the placement ring 6 is used to position the product to prevent it from shifting during the stamping process. Then, the punch 3 drives the die 4 to punch and stamp the product. During this process, the pressing ring 5 will first contact the placement ring 6 on the workbench 2 and push the placement ring 6 downward until the placement ring 6 is pushed into the workbench 2. At this time, the product has also completed the corresponding punching and stamping operation. Then, the punch 3 rises partially. The placement ring 6 is limited by the clamping member and is limited inside the workbench 2. The processed product has no obstruction on the workbench 2, and the blanking assembly is used to blank it, eliminating the need for a separate demolding operation.

[0022] A through hole 7 is provided in the middle of the positioning ring 22. A waste hole 8 penetrates through the workbench 2 directly below the through hole 7. The pressing die 4 is the same size as the through hole 7. During the processing, the pressing die 4 punches the product, and the generated waste falls off from the waste hole 8 for recycling and secondary utilization.

[0023] The pressing ring 5 is located directly above the placement ring 6. The inner diameter of the pressing ring 5 is the same as that of the placement ring 6, and the outer diameter is smaller than that of the placement ring 6. A sunken ring groove 9 is provided on the surface of the workbench 2 below the placement ring 6.

[0024] On the basis of the above, when the pressing ring 5 moves downward, the pressing ring 5 can push the placement ring 6 into the inner part of the ring groove 9.

[0025] The lifting member is located inside the ring groove 9. The lifting member includes a plurality of lifting rods 10 and a lifting tube 11. The top end of the lifting rod 10 is connected to the bottom of the placement ring 6, and the bottom end is inserted into the inner part of the lifting tube 11. The bottom end of the lifting tube 11 is fixed inside the ring groove 9. A connecting spring 12 is sleeved outside the lifting rod 10 and the lifting tube 11. The top end of the connecting spring 12 is connected to the outer wall of the lifting rod 10, and the bottom end is fixed to the bottom of the ring groove 9.

[0026] Furthermore, when the placement ring 6 is retracted into the inner part of the ring groove 9 under force, it will drive the lifting rod 10 to move downward into the lifting tube 11. When the punch 3 and the pressing die 4 do not descend, the connecting spring 12 pushes up the lifting rod 10, and the lifting rod 10 pushes up the placement ring 6, so that the placement ring 6 is located above the ring groove 9 to provide positioning operation for the placement of the product.

[0027] A limiting hole 13 is also provided on the outer wall of the lifting rod 10. The limiting hole 13 faces the side of the clamping member. The limiting hole 13 is used to cooperate with the clamping member to limit the placement ring 6 inside the ring groove 9.

[0028] The blanking assembly includes a support platform 14 fixed on the outer wall of the workbench 2 and a first electric push rod 15 installed on the support platform 14. The output shaft of the first electric push rod 15 extends to one side of the placement ring 6. A push plate 16 is installed at the end of the output shaft, and a limiting tube 17 fixed on the workbench 2 is sleeved outside the output shaft.

[0029] When the product stamping and punching are completed, and the placement ring 6 is also limited in the ring groove 9 by the clamping member, the product is placed flat on the workbench 2. At this time, the output shaft of the first electric push rod 15 pushes the push plate 16 to move, and the product is pushed out from below the punch 3, eliminating the demoulding step compared with the traditional production method.

[0030] Further, a recessed firmware platform 18 is provided at the edge of the workbench 2 on the other side of the blanking assembly. The clamping member is installed on the firmware platform 18. The clamping member includes a second electric push rod 19 installed on the firmware platform 18 and a limiting rod 20 installed at the end of the output shaft of the second electric push rod 19. When the placement ring 6 is retracted into the ring groove 9 under the pressure of the pressure ring 5, the end of the limiting rod 20 is inserted into the limiting hole 13 on the outer wall of the lifting rod 10;

[0031] A blanking plate 21 extending from the top edge of the firmware platform 18 to the other edge of the firmware platform 18 is connected at the top edge of the firmware platform 18. The extending direction of the blanking plate 21 is the same as the extending direction of the first electric push rod 15 and the push plate 16;

[0032] On the above basis, when the positioning ring 22 is processed, the placement ring 6 is pushed up by the lifting rod 10 and the connecting spring 12. The placement ring 6 is located above the ring groove 9, providing a positioning function for the placement of the positioning ring 22 on the workbench 2. The positioning ring 22 is placed inside the placement ring 6, and then the punching machine body 1 is controlled to work. The positioning ring 22 is processed by the punch 3 and the die 4. During the process of the die 4 descending, the pressure ring 5 will contact the placement ring 6, and then the pressure ring 5 slowly presses the placement ring 6 downward and pushes it into the ring groove 9. During this process, when the placement ring 6 is not completely immersed in the ring groove 9, it will also provide a limiting function for the positioning ring 22. At the same time, the die 4 and the punch 3 partially complete the stamping and punching of the positioning ring 22;

[0033] Further, after the stamping and punching are completed, the placement ring 6 is also completely immersed in the ring groove 9. At the same time, the height of the limiting hole 13 is limited so that after the placement ring 6 is immersed in the ring groove 9, the limiting hole 13 and the limiting rod 20 have the same height. Then the second electric push rod 19 drives the limiting rod 20 to be inserted into the limiting hole 13 to limit the placement ring 6 in the ring groove 9. Then the punching machine body 1 is controlled to drive the punch 3 and the die 4 to reset, and the blanking assembly is used to push the positioning ring 22 from the workbench 2 onto the blanking plate 21 to complete the blanking of the positioning ring 22.

[0034] After the blanking is completed, the second electric push rod 19 is controlled to drive the limiting rod 20 to reset. The placement ring 6 is restored to the surface of the workbench 2 under the resilience of the lifting rod 10 and the connecting spring 12 to continue the next round of stamping and punching operations.

[0035] On the basis described above, during the stamping and punching process of the positioning ring 22, there is no need to set a groove for placing the positioning ring 22. By using the ascending and descending placement ring 6 to provide positioning for the positioning ring 22, it is prevented from shifting during the stamping and punching process, so that the positioning ring 22 will not be deformed during the stamping and punching process. Moreover, after the processing is completed, there is no need for a demolding step, and the blanking of the product can be directly completed by using the blanking component, thereby improving the overall processing efficiency.
