All in all, the vacuum high-pressure gas quenching process has the advantages of free control of the heating and cooling rates. Different process parameters can be programmed to achieve the desired microstructure and performance.
With the continuous development of cold heading technology and cold extrusion technology in recent years, new production technologies are emerging and new development trends are as follows:
restraint stamping
The punching hole whose distance between the outer edge and the inner hole edge is smaller than the plate thickness, the punching hole whose inner diameter is larger than one half of the outer diameter and the height is more than 1.5 times of the inner diameter, has better punching effect. Due to the close distance between the outer shape and the edge of the inner hole, the force of the punching pin affects the outer shape, and the size of the outer shape also changes. In order to prevent changes in the external dimensions, this part must be constrained. Due to the restraining force, the stamping part is in the state of compressive stress. In this state of stamping the compressive stress, the stamping effect of the full bright belt can be obtained by taking appropriate clearance
