The four first bearing seats 261 are connected to the first connecting rod 262 through a rotating shaft. The side wall of the buffer frame 27 is symmetrically embedded with two slide grooves 271. The side walls of the two slide grooves 271 are slidably connected to the slider 272. The side wall of the slider 272 is provided with a first spring 273. The side wall of the slider 272 is fixedly connected to the limit rod 274. One end of the limit rod 274 passes through the side wall of the buffer frame 27 and extends to the outer wall. The side wall of the slider 272 is connected to the first connecting rod 262 through a rotating shaft.

[0022] It should be noted that in this embodiment, when the stamping mechanism 11 stamps the stamped part, pressure is generated on the processing die 25. At this time, the processing die 25 drives the connecting block 24 to move downward in the buffer groove 12, and then squeezes the hydraulic buffer 231. The hydraulic buffer 231 performs the first buffering on the processing die 25.

[0023] Please refer to the attached Figure 1 , 2 As shown in Figures 3 and 4, in a preferred embodiment of the utility model, a second buffer component 28 is symmetrically provided at the bottom of the buffer frame 27, and a lower connecting rod component 29 is provided at the top of the fixed frame 21.

At the same time, when the buffer frame 27 descends, it drives the vertical rod 281 to squeeze the second spring 282 to perform a third buffer on the processing mold 25. After the punching of the workpiece is completed, all springs restore their elastic force to restore the processing mold 25 to its original position for the next buffering.

[0025] The working principle of the utility model is:

[0026] The staff first places the stamping part on the processing die 25, and then starts the stamping mechanism 11. When the stamping mechanism 11 stamps the stamping part, pressure is generated on the processing die 25. At this time, the processing die 25 drives the connecting block 24 to move downward in the buffer groove 12, and then squeezes the hydraulic buffer 231. The hydraulic buffer 231 performs the first buffering on the processing die 25. While the processing die 25 descends, one end of the first connecting rod 262 rotates in the first bearing seat 261, and the other end pushes the slider 272. One end of the second connecting rod 292 One end rotates in the second bearing seat 291, and the other end cooperates with the other end of the first connecting rod 262 to push the slider 272 to move in the slide groove 271. At this time, the slider 272 drives the limiting rod 274 to squeeze the first spring 273 to perform a second buffer on the processing mold 25. At the same time, when the buffer frame 27 descends, it drives the vertical rod 281 to squeeze the second spring 282 to perform a third buffer on the processing mold 25. After the workpiece is stamped, all springs restore their elastic force to restore the processing mold 25 to its original position for the next buffer.
