[0019] Furthermore, a damper is fixedly connected inside the fixing column, and the damper is located inside the second spring.

[0020] By adopting the above technical solution, through the cooperation between the spring 2 and the damper, the pressure generated by the collision between the upper module and the lower module can be effectively alleviated, and the damage such as cracks and deformation of the upper module and the lower module caused by stress concentration can be reduced.

[0021] Furthermore, a plurality of auxiliary blocks are evenly and symmetrically fixedly connected to the top of the lower module, a groove is provided in the middle of the plurality of auxiliary blocks, and a plurality of slots matching the size of the auxiliary blocks are evenly opened at the bottom of the upper module.

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The embodiment of the present application discloses a punching machine die for producing steel nails.

[0034] Reference Figure 1A punching machine mold for steel nail production comprises a base 1, a plurality of support columns 2 are symmetrically fixedly connected to the top of the base 1, a top plate 3 is fixedly connected to the top of the plurality of support columns 2, a hydraulic cylinder 4 is fixedly connected to the top of the top plate 3, a sliding plate 5 is slidably connected to the plurality of support columns 2, an output end of the hydraulic cylinder 4 is fixedly connected to the top of the sliding plate 5, an upper module 6 is slidably arranged at the bottom of the sliding plate 5, a connecting plate 61 is symmetrically fixedly connected to the top of the upper module 6, a support block 7 is fixedly connected to the top of the support block 7, a fixed plate 8 is fixedly connected to the top of the fixed plate 8, a lower module 9 is installed on the top of the fixed plate 8, a limiting assembly 10 is installed on the top of the sliding plate 5, a clamping assembly 11 is installed on the top of the fixed plate 8, a buffer assembly 12 is installed on the top of the fixed plate 8, a plurality of auxiliary blocks 13 are evenly and symmetrically fixedly connected to the top of the lower module 9, a groove is arranged in the middle of the plurality of auxiliary blocks 13, and a plurality of card slots matching the size of the auxiliary blocks 13 are evenly opened at the bottom of the upper module 6.

[0035] When in use, first place the steel nail template to be punched in the groove inside the auxiliary block 13, then start the hydraulic cylinder 4 to push the sliding plate 5 to drive the upper module 6 to move downward, and punch the steel nail template through the extrusion and fit of the upper module 6 and the lower module 9. During the descent of the upper module 6, the bottom of the sliding plate 5 will contact the buffer component 12. The buffer component 12 can effectively reduce the pressure generated by the collision between the upper module 6 and the lower module 9, reduce the damage such as cracks and deformation of the upper module 6 and the lower module 9 caused by stress concentration, and reduce the upper module 6 and the lower module 9. Fatigue damage is prevented, thereby extending the service life of the stamping upper module 6 and the lower module 9, so as to complete the overall stamping. Secondly, when the upper module 6 is damaged and needs to be replaced, the connection between the sliding plate 5 and the upper module 6 can be released by pulling the limit assembly 10, so that the upper module 6 can be easily taken out from the sliding plate 5 for replacement, and when the lower module 9 is damaged and needs to be replaced, the clamping assembly 11 can be started to release the limit fixation of the lower module 9, so that the device does not need to perform unnecessary operations, and the upper module 6 and the lower module 9 can be quickly and conveniently replaced and repaired, which effectively improves the efficiency of stamping.

[0036] Reference Figure 1 and Figure 2 The limiting assembly 10 includes a fixed block 101 symmetrically fixedly connected to the top of the sliding plate 5, and a through hole 102 is symmetrically opened on the fixed block 101. A through groove matching the size of the through hole 102 is symmetrically opened on the connecting plate 61. Moving grooves are opened on both sides of the through hole 102. A spring 103 is fixedly connected inside the moving groove. A clamping block 104 is fixedly connected to one end of the spring 103. The clamping block 104 is slidably connected in the moving groove. An adjusting plate 105 is slidably arranged in the through groove inside the connecting plate 61, and limiting grooves 106 of the same size as the clamping block 104 are opened on both sides of the adjusting plate 105.

[0037] During use, when the upper module 6 is damaged and needs to be replaced, the adjustment plate 105 can be pulled out from the through hole 102. When the adjustment plate 105 moves, the limiting connection between the block 104 and the limiting groove 106 can be released according to the guidance of the arc-shaped end of the block 104, so that the adjustment plate 105 can be quickly drawn out from the through hole 102 and the through groove. When the adjustment plate 105 is drawn out of the through groove, the connecting plate 61 loses the limiting fixation of the adjustment plate 105 and will separate from the sliding plate 5, thereby The upper module 6 can be quickly replaced and repaired. When the new upper module 6 is reinserted, the adjustment plate 105 can be inserted into the through groove and the through hole 102 again. At this time, the limit groove 106 will be parallel to the block 104. According to the elastic extrusion of the spring 103, the block 104 will be pushed into the limit groove 106, so as to fix the adjustment plate 105 inside the through hole 102. The connecting plate 61 is limited and fixed by the adjustment plate 105 so that the upper module 6 can be stabilized at the bottom of the sliding plate 5.

[0038] Reference Figure 1 and Figure 3 The clamping assembly 11 includes a bidirectional threaded rod 110 which passes through and is rotatably connected to the inside of the fixed plate 8, one end of the bidirectional threaded rod 110 is fixedly connected to a knob 111, and a clamping block 112 is symmetrically threaded on the knob 111. A guide column 113 is fixedly connected to the inside of the fixed plate 8, and the bottom of the clamping block 112 is slidably connected to the guide column 113. A sliding groove 114 is symmetrically opened on the top of the fixed plate 8, and the bottom of the clamping block 112 is slidably connected inside the sliding groove 114.

[0039] During use, when the lower module 9 is damaged and needs to be replaced, the knob 111 can be manually turned to drive the bidirectional threaded rod 110 to rotate. When the bidirectional threaded rod 110 rotates, the two clamping blocks 112 will move away from each other on the bidirectional threaded rod 110 under the guidance of the guide column 113 and the slide groove 114. The two clamping blocks 112 moving away from each other can release the clamping fixation of the lower module 9, so that the lower module 9 can be quickly replaced and repaired. When the new lower module 9 is put back on the top of the fixing plate 8, the knob 111 can be rotated in the opposite direction to drive the two clamping blocks 112 to gradually move closer until one side of the clamping block 112 fits against one side of the lower module 9, so as to stabilize the lower module 9 on the top of the fixing plate 8.

[0040] Reference Figure 1 and Figure 4The buffer assembly 12 includes two fixed columns 121 symmetrically fixedly connected to the top of the fixed plate 8, the two fixed columns 121 are internally slidably connected with a sliding column 122, a spring 123 is fixedly connected inside the fixed column 121, one end of the spring 123 is fixedly connected to the bottom of the sliding column 122, a damper 124 is fixedly connected inside the fixed column 121, and the damper 124 is located inside the spring 123.

[0041] When in use, during the stamping process, the bottom of the sliding plate 5 will come into contact with the sliding column 122. As the sliding plate 5 gradually descends, the sliding column 122 will be driven to move toward the inside of the fixed column 121. At this time, the bottom of the sliding column 122 will squeeze the spring 2 123 and the damper 124 inside the fixed column 121. Through the mutual cooperation of the spring 2 123 and the damper 124, the pressure generated by the collision between the upper module 6 and the lower module 9 can be effectively reduced, and the damage such as cracks and deformation of the upper module 6 and the lower module 9 caused by stress concentration can be reduced, and the fatigue damage of the upper module 6 and the lower module 9 can be reduced, thereby extending the service life of the stamping upper module 6 and the lower module 9.

[0042] The implementation principle of the punching machine mold for steel nail production in this embodiment is as follows: when in use, first place the steel nail template to be punched in the groove inside the auxiliary block 13, then start the hydraulic cylinder 4 to push the sliding plate 5 to drive the upper module 6 to move downward, and punch the steel nail template through the extrusion and fit of the upper module 6 and the lower module 9. During the descent of the upper module 6, the bottom of the sliding plate 5 will contact the sliding column 122. As the sliding plate 5 gradually descends, it will drive the sliding column 122 to move toward the inside of the fixed column 121. At this time, the bottom of the sliding column 122 will squeeze the spring 2 123 and the damper 124 inside the fixed column 121. Through the mutual cooperation of the spring 2 123 and the damper 124, the pressure generated by the collision between the upper module 6 and the lower module 9 can be effectively reduced, and the damage such as cracks and deformation of the upper module 6 and the lower module 9 caused by stress concentration can be reduced, and the fatigue damage of the upper module 6 and the lower module 9 can be reduced, thereby extending the service life of the stamping upper module 6 and the lower module 9, thereby completing the overall stamping;

[0043] When the upper module 6 is damaged and needs to be replaced, the adjustment plate 105 can be pulled out from the through hole 102. When the adjustment plate 105 moves, the limiting connection between the block 104 and the limiting groove 106 can be released according to the guidance of the arc-shaped end of the block 104, so that the adjustment plate 105 can be quickly pulled out of the through hole 102 and the through groove. When the adjustment plate 105 is pulled out of the through groove, the connecting plate 61 loses the limiting fixation of the adjustment plate 105 and will separate from the sliding plate 5, thereby aligning the upper module 6. The block 6 can be quickly replaced and repaired. When the new upper module 6 is reinserted, the adjustment plate 105 can be inserted into the through groove and the through hole 102 again. At this time, the limit groove 106 will be parallel to the card block 104. According to the elastic extrusion of the spring 103, the card block 104 will be pushed into the inside of the limit groove 106, so as to fix the adjustment plate 105 inside the through hole 102. The connection plate 61 is limited and fixed by the adjustment plate 105 so that the upper module 6 can be stably at the bottom of the sliding plate 5;

[0044] In addition, when the lower module 9 is damaged and needs to be replaced, the knob 111 can be manually turned to drive the two-way threaded rod 110 to rotate. When the two-way threaded rod 110 rotates, the two clamping blocks 112 will move away from each other on the two-way threaded rod 110 under the guidance of the guide column 113 and the slide groove 114. The two two-way threaded rods 110 that move away from each other can release the clamping fixation of the lower module 9, so that the lower module 9 can be quickly replaced and repaired. When the new lower module 9 is put back on the top of the fixed plate 8, the knob 111 can be rotated in the opposite direction to drive the two clamping blocks 112 to gradually move closer until one side of the clamping block 112 fits against one side of the lower module 9, so as to stabilize the lower module 9 on the top of the fixed plate 8. In this way, the device does not need to perform unnecessary operations, and the upper module 6 and the lower module 9 can be quickly and conveniently replaced and repaired, effectively improving the efficiency of stamping.
