Dongguan sheet metal processing factory analysis sheet metal processing _ in our daily life, precision sheet metal processing is not common, but in industrial processing, he has an important role, so how much do you know about sheet metal processing? Next, follow Dongguan sheet metal processing factory to have a detailed look. Cold machining of sheet metal processing: usually refers to the cutting of metal, that is, using cutting tools from metal materials (Blank) Or remove the excess metal layer from the workpiece so that the workpiece can obtain a machining method with a certain shape, dimensional accuracy and surface roughness. Such as turning, drilling, milling, planing, grinding, broaching, etc. In Metal Technology, corresponding to hot processing, cold processing refers to the processing technology that causes plastic deformation of metal at lower than the crystallization temperature, such as cold rolling, cold pulling, cold forging, stamping, cold extrusion, etc. Cold machining has great resistance to deformation, which can improve the hardness and strength of the workpiece by means of machining hardening while forming the metal, but will reduce the plasticity. Cold machining is suitable for machining metal parts with small cross-sectional size and high requirements for machining size and surface roughness. Sheet metal processing is a key technology that sheet metal technicians need to master, and it is also an important process for sheet metal product forming. It includes not only traditional methods and process parameters such as cutting and blanking, blanking and bending forming, but also various cold stamping die knots and process parameters, various equipment working principles and operation methods, it also includes new stamping techniques and new processes.
