Description

Technical Field

[0001] The utility model relates to the field of punching devices, in particular to a punching device for screw production. Background Art

[0002] As we all know, screws are tools that use the physical and mathematical principles of the inclined circular rotation of an object and friction to gradually tighten objects and parts.

[0003] The patent with publication number CN218555391U proposes a punching device for screw production, including a base and a punching mechanism arranged on the top of the base, a stepper motor is fixedly installed at the bottom of the base, and the output end of the stepper motor is fixedly connected to a shock absorber through the base. The punching mechanism moves downward to punch the screw workpiece on the workbench, so that the workbench moves downward under the punching force of the punching mechanism, and the shock absorber and the shock-absorbing spring are compressed. At the same time, the workbench will contact the load-bearing block, and the load-bearing block plays a role in bearing and limiting the force and position of the downward movement of the workbench. In summary, the punching force and vibration force are greatly reduced by the shock absorber and the shock-absorbing spring, which effectively avoids the situation where the vibration force generated by the punching is too large and easily causes damage to the workbench, effectively improves the service life of the workbench, and further reduces the number of repairs of the workbench.

[0004] When the above structure is in use, the shock absorbing spring part lacks a guide component. When the workbench descends, the shock absorbing spring will bend, which will affect the stability of the workbench when in use. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 A punching device for screw production includes a processing table 1, a bottom die 2 is arranged above the processing table 1, a first lifter 6 is fixedly arranged above the bottom die 2, a top die 7 is fixedly arranged at the output end of the first lifter 6, a die groove 4 is arranged inside the bottom die 2, a bottom plate 5 is arranged at the bottom of the die groove 4, a plurality of guide rods 9 penetrating the processing table 1 are arranged at the lower end of the bottom die 2, a plurality of first springs 8 penetrating the guide rods 9 are arranged between the bottom die 2 and the processing table 1, a cavity 10 is arranged in the middle part of the processing table 1, a second lifter 11 is fixedly arranged at the lower end of the bottom die 2, and the output end of the second lifter 11 penetrates the bottom The mold 2 is connected to the bottom plate 5. A baffle 17 for limiting the guide rod 9 is provided below the processing table 1. A plurality of buffer components are provided on the peripheral side of the bottom mold 2. In this structure, the first lifter 6 is started to lower the top mold 7, and the designated screw workpiece can be stamped and shaped in the mold groove 4. At this time, the bottom mold 2 is lowered, which will cause the first spring 8 to be compressed. The guide rod 9 can provide a guiding effect to the first spring 8, which can improve the stability of the bottom mold 2 when it is lifted and lowered. The baffle 17 can limit the guide rod 9. When the first spring 8 is not compressed to the limit, the bottom mold 2 can stop falling, which can further improve the stability of the bottom mold 2 when it is in use.

[0024] After a single punching of the screw workpiece is completed, the top die 7 is reset, and the second lifter 11 is started, so that the bottom plate 5 can push the screw workpiece out of the die groove 4, so that the structure is convenient for unloading.

[0025] The elastic force of the first spring 8 alone is not enough to provide a good buffering effect for the bottom mold 2. A plurality of guide grooves 14 are provided on the peripheral side of the processing table 1. The buffer assembly includes a support rod 12, a guide block 13 and a telescopic rod 15. The top end of the support rod 12 is rotatably connected to the bottom mold 2, and the bottom end of the support rod 12 is rotatably connected to the guide block 13. The guide block 13 is slidably connected to the guide groove 14. The telescopic rod 15 is fixed on the peripheral side of the processing table 1. A second spring 16 is provided inside the telescopic rod 15. The front end of the telescopic rod 15 is connected to the guide block 13. When the bottom mold 2 is descending, the support rod 12 is tilted, which will cause the telescopic rod 15 to contract and the second spring 16 to be compressed, thereby providing a good buffering effect for the bottom mold 2.

[0026] When the telescopic rod 15 is extended or retracted, the guide block 13 will slide in the guide groove 14. The bottom end of the guide block 13 and the guide groove 14 are both cross structures, which can make the movement of the guide block 13 more stable.

[0027] In this structure, the buffer component is made of metal, and the material of the buffer component is iron, which can increase the service life of the buffer component.

[0028] The top mold 7 directly collides with the bottom mold 2, which will damage the bottom mold 2 or the top mold 7 in the long run. The rubber ring 3 is fixedly arranged on the peripheral side of the bottom mold 2 to avoid the top mold 7 from directly colliding with the bottom mold 2 and to increase the service life of the bottom mold 2 and the top mold 7.
