Sheet Metal Processing is now a very prosperous business. As the industry comes up, it often brings a lot of additional problems. For example, the error rate of the product will increase when the workload is large, and the problem parts will also increase. Basically, the problems that arise are concentrated on the deformation of sheet metal processing parts and the lack of rebound during sheet metal processing. So how to deal with the deformation in sheet metal processing?

For many sheet metal processing, because a lot of processing needs to be done for sheet metal parts, especially in the cooling process of parts, the type of quenching medium, cooling performance, hardenability, etc. of sheet metal processing are related to deformation. Changes in cooling performance can be adjusted by changing the viscosity, temperature, liquid level pressure of the medium, using additives, stirring, etc. The higher the viscosity of the quenching oil, the higher the temperature, the smaller the elliptical deformation, and in the static state, the smaller the deformation.

　　In the heat treatment of forgings, the way to reduce deformation of parts is to hang them vertically as much as possible, place them vertically at the bottom of the furnace, and support them horizontally at two points. The fulcrum position is between one-third and one-quarter of the total length. Fourth, it is placed flat on the heat-resistant steel tooling.

　　Decompression quenching in sheet metal processing is achieved by reducing the liquid level pressure of the quenching medium, thereby prolonging the steam film stage. The cooling rate in the high temperature area decreases, so that the cooling rate of each part of the part is uniform. The parts are cooled in oil from the quenching temperature to a temperature slightly higher than the Ms point, then released and maintained in an atmosphere to make the overall temperature of the parts uniform, and then cooled in oil to make the martensite phase transformation even, and the irregularity of deformation is greatly improved.
