Precision metal stamping is a manufacturing process used to convert flat metal sheets into specific shapes. It is a complex process that can include a number of metal forming techniques — blanking, punching, bending and piercing, to name a few. Pieces of flat sheet metal, typically referred to as blanks, is fed into a sheet metal stamping press that uses a tool and die surface to form the metal into a new shape. The stamping process can occur in several different ways, including a single process with one or more dies, a series of progressive dies in the same machine, or in transfer stamping where the work piece is moved between dies on separate machines.It refers to the use of punches and dies to deform or break stainless steel, iron, aluminum, copper and other plates and other materials to achieve a certain shape and size.
There are many names for precision metal stamping, and sometimes it is also called sheet metal forming, but there is a slight difference. Sheet forming is carried out using sheets, thin-walled tubes, thin profiles, etc. as raw materials. The forming method of plastic processing is collectively referred to as sheet forming. At this time, the deformation of the thick plate direction is generally not considered.
The precautions for the processing of common precision metal stamping parts should be mainly described from the following aspects:
1. In the daily processing of precision metal stamping parts, the punching size is too large or small, and the size of the punch is quite different;
2. When the punching edge is worn, the tensile stress of the material increases, and the tendency of the precision metal stamping parts to turn over and twist increases. When turning the material, the punching size will become smaller;
3.The high pressure of precision metal stamping parts processing on the material will cause the material to produce plastic deformation, which will cause the punching size to become larger. When the strong pressure is reduced, the punching size will become smaller;
4.The shape of the punch edge. If the end is trimmed with a bevel or arc, the punching part will not be easily turned or twisted due to the slowing of the punching force.
Precision metal stamping parts processing is one of the main methods of metal plastic processing. Stamping parts are used in various mechanical equipment, so the processing quality of metal stamping parts must be guaranteed.
Therefore, during the processing, Worthy hardware strictly abides by the above principles and standardize operations to ensure the quality of the processed products.
