[0028] The effect achieved by the entire embodiment 1 is that when the tension wire clamp is stamped, the lower die 316 moves downward under pressure, and first, the pressure on the lower die 316 is absorbed by the compression spring 309 and the second damper 310 to achieve the purpose of shock absorption and buffering, and then the shock absorbing spring 303 is driven to move inside the square groove 302 under the action of the second mounting block 308, the connecting rod 306 and the first mounting block 305, and the force on the lower die 316 is absorbed by the shock absorbing spring 303 and the first damper 304, and at the same time, the pressure on the lower die 316 can be absorbed again under the action of the buffer spring 313 and the third damper 314.

When the material is fixed, the stamping device drives the upper die 104 to move downward to stamp the material. During the stamping process, the lower die 316 is pressed and moves downward. First, Under the action of the compression spring 309 and the second damper 310, the pressure exerted on the lower mold 316 is absorbed to achieve the purpose of shock absorption and buffering.
