Description

Technical Field

[0001] This utility model relates to the field of punching and forming technology, and in particular to a production tooling for punching and forming automotive door locks. Background Technology

[0002] Punching is a plastic processing method that uses punching dies to punch holes of the required shape and size into metal sheets. It falls under the category of punching technology. In the production of automobile door panels, it is necessary to punch holes in the lock hole positions of the door panels so that the door lock can be installed in the punched positions during automobile production.

[0003] When punching holes in the lock holes of a car door panel, the car door panel needs to be placed in the punching position. Then, the output end of the punching equipment can be used to punch the holes in the car door panel. The waste material under the punch needs to be cleaned up by the operator in time to ensure that subsequent punching will not be affected.

[0004] However, the operation of punching equipment is continuous, which requires timely cleaning of the punching area. If the punching area is not cleaned in time, waste material will affect the subsequent punching of the car door panel, resulting in inconsistent door lock positions that need to be corrected, thus affecting punching efficiency. In view of this, this utility model proposes a production tooling for punching and forming car door locks. Utility Model Content

[0005] The purpose of this invention is to address the problem in the background technology that if the punching position is not cleaned in time, the waste material will affect the subsequent punching of the car door panel, resulting in uneven door lock positions that need to be corrected, thus affecting the punching efficiency. The invention proposes a production tooling for punching and forming car door locks.

[0032] Example

[0033] like Figures 1 to 3 As shown, this utility model proposes a production fixture for punching and forming automotive door locks, including a machine base 1. The machine base 1 is hollowed out, and a support frame 2 is fixedly connected to the top of the machine base 1. The support frame 2 is arranged in an inverted "L" shape. A punching head 3 is fixedly connected to the support frame 2 near the machine base 1. The machine base 1 can support the support frame 2 to control the punching head 3 to perform punching. A punching table 4 is arranged below the punching head 3. A telescopic rod 5 is fixedly connected to the bottom of the punching table 4. The telescopic rod 5 can cooperate with the punching head 3 to control the punching table 4 to descend, avoiding uneven end faces at the punching position. The end of the telescopic rod 5 away from the punching table 4 is... A rack 6 is fixedly connected to the inside of the machine base 1 near the bottom. A gear 7 is fixedly connected to the outside of the punching table 4. When the punching table 4 moves, it can drive the rack 6 to drive the gear 7 to rotate. A rotating rod 8 is fixedly connected inside the gear 7. A swing rod 10 is fixedly connected to both ends of the rotating rod 8. The gear 7 can drive the rotating rod 8 and the swing rod 10 to rotate. A rotating shaft 11 is rotatably connected to the opposite side of the swing rod 10 away from the rotating rod 8. A cleaning component is set on the outside of the rotating shaft 11 away from the swing rod 10. The cleaning component is used to sweep away the waste material under the punching.

[0034] For further details, please refer to Figure 6 and Figure 7 The cleaning assembly includes a telescopic box 12, which is fixedly connected to the outside of the rotating shaft 11 away from the swing rod 10. The telescopic box 12 can rotate by the rotating shaft 11. A cleaning brush 15 is slidably connected inside the telescopic box 12, which can drive the cleaning brush 15 to clean. A spring 13 is fixedly connected to the side of the cleaning brush 15 near the telescopic box 12. The spring 13 can push the cleaning brush 15 to clean the top of the punching platform 4. The end of the spring 13 away from the cleaning brush 15 is fixedly connected inside the telescopic box 12. A push rod 14 is fixedly connected to the side of the cleaning brush 15 near the spring 13. The push rod 14 can assist the spring 13 in pushing the cleaning brush 15. The end of the push rod 14 away from the cleaning brush 15 is fixedly connected inside the telescopic box 12. The push rod 14 is located inside the spring 13. The push rod 14 can also prevent the spring 13 from bending and can assist the spring 13 in extending and retracting.

[0035] For further details, please refer to Figure 4 and Figure 5 A support plate 9 is rotatably connected to the outside of the rotating rod 8 near the swing rod 10. The support plate 9 can support the rotation of the rotating rod 8. The support plate 9 is fixedly connected to the inside of the machine base 1 near the bottom. The support plate 9 can fix the rotation position of the rotating rod 8 and the gear 7. A winding groove 16 is opened inside the support plate 9 near the rotating rod 8. An auxiliary component is set inside the winding groove 16. The auxiliary component is used to assist the rotation of the rotating rod 8. The auxiliary component includes a coil spring 17. One end of the coil spring 17 is fixedly connected to the outside of the rotating rod 8. The coil spring 17 can control the rotating rod 8 to drive the gear 7 and the rotating rod 8 to reset when the rotating rod 8 moves upward with the punching table 4 and drives the rack 6. A connecting block 18 is fixedly connected to the end of the coil spring 17 away from the rotating rod 8. The connecting block 18 can fix the position of the coil spring 17. The connecting block 18 is fixedly connected inside the winding groove 16.

[0036] In this embodiment, when punching, the car door panel is placed on the punching platform 4. At this time, the support frame 2 supported by the machine 1 can control the punching head 3 to press down on the punching platform 4. This allows the punching head 3 to work with the punching platform 4 to punch the lock hole position of the car door panel. The telescopic rod 5 can provide slow downward movement to ensure that the punching head 3 has a neat punching cut surface.

[0037] When the punching platform 4 moves downward, it drives the rack 6 to drive the gear 7 and the rotating rod 8 to rotate. In this way, the rotating rod 8, supported by the support plate 9, drives the swing rod 10 to swing. When the swing rod 10 swings, it drives the telescopic box 12 and the cleaning brush 15 to pass above the punching platform 4. The spring 13 and the push rod 14 push the cleaning brush 15 to ensure that the cleaning brush 15 is in contact with the surface of the punching platform 4. Even during punching, the telescopic box 12 and the cleaning brush 15 rotate by the rotating shaft 11, thereby ensuring that the telescopic box 12 will not block the rotation of the swing rod 10. In this way, the cleaning brush 15 can clean up the impurities.

[0038] When the telescopic rod 5 drives the punching table 4 to reset, the punching table 4 can drive the gear 7 and the rotating rod 8 to rotate in opposite directions. In this way, the rotating rod 8 will drive the swing rod 10 to reset. The swing rod 10 can then drive the cleaning brush 15 to clean the waste material under the punch. When the swing rod 10 resets, the coil spring 17 can release its elasticity inside the winding groove 16 by relying on the connecting block 18, thereby allowing the coil spring 17 to push the rotating rod 8 to reset, thus assisting the swing rod 10 to reset.

[0039] It should be noted that while the punching table 4 assists in punching, the punching table 4 drives the rack 6 to drive the gear 7 and the rotating rod 8 to rotate. In this way, the rotating rod 8 can drive the swing rod 10 to make a fan-shaped movement along the outside of the punching table 4. The swing rod 10 will drive the cleaning brush 15 to clean the punching table 4. The cleaning brush 15 relies on the rotation of the telescopic box 12 and the rotating shaft 11 to ensure that the telescopic box 12 is not affected by obstructions, thereby increasing the effect of cleaning the punching table 4 while punching.

[0040] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
