It should be noted that, after the male die block 323 of the upper die holder 310 is installed, the hydraulic cylinder 214 is started to push the lower die plate 210 to move towards the upper die holder 310 until the bottom of the lower die plate 210 is attached to the male die block 323, and the second spring 312 and the third spring 317 are compressed under the force of the second spring 312 and the third spring 317, so that the upper die holder 310 is matched with the lower die plate 210 to clamp the male die block 323, and a sufficient stamping distance is ensured between the male die block 323 and the female die block 324, and after the workpiece is stamped, the bottom of the lower die plate 210 is always attached to the male die block 323 in the resetting process and after the workpiece is reset, so that the male die block 323 is always kept in the upper die block mounting groove 322 when the upper die holder 310 is reset.
From the above, the upper module mounting groove 322 and the lower module mounting groove 321 are designed on the lower die holder 31 and the upper die holder 310, so that the module is not required to be disassembled during the installation and replacement, the module is not required to be positioned during the installation process, the module installation and replacement speeds are increased, and the processing efficiency of the workpiece is indirectly improved.
When the stamping die runs, the hydraulic cylinder 214 is started to push the lower pressing plate 210 to downwards displace along the guide post 26, the bottom of the lower pressing plate 210 props against the male die block 323 arranged in the upper die block mounting groove 322, the male die block 323 and the upper die base 310 are pushed to synchronously move along the guide rod 39 towards the lower die base 31 until the male die block 323 and the female die block 324 arranged in the lower die block mounting groove 321 finish stamping of a workpiece.
As shown in fig. 6 and 7, in the process that the upper die holder 310 moves along the guide rod 39 toward the lower die holder 31, the second springs 312 sleeved on the periphery of the guide rod 39 are stressed and gradually compressed, meanwhile, the two support rods 320 of the support rod assembly 319 push the moving block 316 to move on the limit rod 315 in a direction away from the welding block 314, and the third springs 317 sleeved on the periphery of the limit rod 315 are stressed and gradually compressed, and at this time, the second springs 312 and the third springs 317 are in an energy storage state.
When the workpiece is stamped, the hydraulic cylinder 214 pulls the lower platen 210 to move upwards along the guide post 26, the second spring 312 and the third spring 317 gradually extend, so that the elastic potential energy stored in the compressed state is gradually released, the second spring 312 pushes the upper die holder 310 to move upwards along the guide rod 39, the third spring 317 pushes the moving block 316 to move upwards on the limit rod 315 towards the welding block 314, and the two support rods 320 of the support rod assembly 319 push the upper die holder 310 to move upwards along the guide rod 39, so as to complete the resetting of the upper die holder 310.
As can be seen from the above description, the cooperation of the second spring 312, the third spring 317 and the stay bar assembly 319 enables the upper die holder 310 and the lower die holder 31 to maintain a certain workpiece processing distance, and the two support bars 320 cooperate with the third spring 317 to lift the upper die holder 310 and cooperate with the stop block 311 to limit the upper die holder 310, so as to improve the stability of the upper die holder 310 moving along the stop bar 315 during the workpiece stamping process, prevent the vibration of the die from affecting the product quality, and meanwhile, the cooperation of the plurality of groups of springs can help the die to quickly recover after each stamping operation, reduce the downtime, accelerate the production rhythm and improve the production efficiency.
