The lifting component 5 includes a mounting base 51, which is fixedly installed on the top of the stamping table 1. A T-shaped groove is provided inside the mounting base 51. A clamp 6 is provided inside the mounting base 51. The clamp 6 includes a mold 61, the bottom of which is embedded in the T-shaped groove. The mounting base 51 positions the mold 61 to prevent shaking during stamping.

By retracting the second hydraulic telescopic rod 65, the connecting plate 64 moves downward, and the connecting plate 64 clamps the mold 61 with the clamping plate 63 to improve the installation stability of the mold 61.

[0034] As the mold 61 wears out with use, the second hydraulic telescopic rod 65 extends to move the connecting plate 64 upward. The connecting plate 64 causes the clamping plate 63 to no longer clamp the mold 61, thereby removing the mold 61 and improving the efficiency of disassembly and replacement.

[0035] The top of the mold 61 is provided with a clamping groove 62, and the bottom of the clamping plate 63 is embedded in the interior of the clamping groove 62.

[0042] When the clamp plate 63 clamps the mold 61, the thickness of the mold 61 for stamping the nut is different due to the different thicknesses of different nuts, the height of the top end of the clamp plate 63 is different when the clamp plate 63 clamps the mold 61, the second hydraulic telescopic rod 65 is extended to make the cooperation plate 64 and the clamp plate 63 slide up and down, so as to adapt to the thickness of the mold 61, and meanwhile the cooperation plate 64 uses the extension plate 57 to lift the starting height plate 56.

[0043] The inside of the stamping table 1 is fixedly installed with a fixing base 55, the top of the fixing base 55 is fixedly installed with a telescopic rod, and the top of the telescopic rod is fixedly connected with the starting height plate 56. The telescopic rod at the top of the fixing base 55 guides the starting height plate 56.

[0044] In the utility model, the thickness of the mold 61 for stamping the nut is different due to the different thicknesses of different nuts, the second hydraulic telescopic rod 65 is extended to adjust the height of the clamp plate 63 and the cooperation plate 64 at the same time, the cooperation plate 64 uses the extension plate 57 to lift the starting height plate 56, the starting height of the first hydraulic telescopic rod 54 is changed, the depth of the mold 61 is prevented from being too deep, and the top rod 52 is lifted to the original height and cannot push out the nut.
