Precision sheet metal manufacturing

The drawing of sheet metal, especially deep drawing, is a kind of difficult process in sheet metal processing. It requires not only the drawing depth as small as possible, the shape as simple and smooth as possible, but also the good plasticity of the material. Otherwise, it is very easy to cause the whole part distortion, local wrinkling, and even the tensile part cracking。
It is produced by stamping on the premise of less data consumption. The parts are light in weight and have good rigidity. After the sheet metal is deformed by plastic deformation, the internal arrangement structure of metal is improved, and the strength of stamping parts is improved。

The precision hardware die stamping has high dimensional accuracy, uniform size of the same die, and good interchangeability. No further machining is needed to meet the general requirements of the device and operation。

In the stamping process, because the appearance of the data is not damaged, it has good appearance quality and beautiful appearance, which provides convenient conditions for surface painting, electroplating, phosphating and other surface treatment。

There are three main stamping processes: blanking, bending and stretching. Different processes have different requirements for plates. The selection of materials should also be considered according to the approximate shape and processing technology of products。

Blanking requires that the plate should have enough plasticity to ensure that the plate will not crack during blanking. Soft materials have good blanking performance, and parts with smooth cross-section and small inclination can be obtained after blanking; the quality of hard materials after blanking is not good, and the cross-section unevenness is large, especially for thick plates. For brittle materials, tearing occurs easily after blanking, especially when the width is very small。

The sheet to be bent should have sufficient plasticity and low yield limit. The sheet metal with high plasticity is not easy to crack when bending, and the sheet with lower yield limit and lower elastic modulus has small springback deformation after bending, so it is easy to obtain the bending shape with accurate size. The material with larger brittleness must have a larger relative bending radius when bending, otherwise it is easy to crack in the bending process。

The drawing of sheet metal, especially deep drawing, is a kind of difficult process in sheet metal processing. It requires not only the drawing depth as small as possible, the shape as simple and smooth as possible, but also the good plasticity of the material. Otherwise, it is very easy to cause the whole part distortion, local wrinkling, and even the tensile part cracking。
