Classification of stamping process

Recommended Posts

The stamping process can be divided into different classes according to different standards.

(1) according to the different deformation properties, it can be divided into separation process and forming process.

Separation process: the material is processed under external force to produce deformation, as used in the deformation part of the equivalent stress reached the shear strength of the material, the material will produce shear cracking and separation, thus forming a certain shape and size of the parts. These stamping processes are generally referred to as separation processes, such as tailoring, punching, blanking, and cutting.

Forming process: under the action of external force, the equivalent stress acting on the deformed part of the material is between the yield limit and the strength limit of the material. The material only produces plastic deformation, so as to obtain a certain shape and size of the parts. These stamping processes are collectively called forming processes, such as bending, drawing, forming and other deformation processes.

(2) according to the basic deformation mode, it can be divided into blanking, bending, drawing and forming.

Punching: Punching, such as punching, blanking, etc., is a process in which materials are cut apart along closed or non-closed contours.

Bending: The stamping process of bending a material into an angle or shape is called bending, such as bending, crimping, twisting, etc.

Drawing: The process of drawing a flat blank into a hollow part, or further changing the shape and size of the hollow part with a drawing die, is called drawing. There are thinner drawing and thinner drawing.

Forming: The stamping process that causes material to deform locally to change the shape of a part or blank is called forming, such as flanging, shrinkage, etc.
