Precision metal stamping parts working procedure and characteristics

Stamping if classified according to the process of forming and separation process can be divided into two processes. Forming process of the index is to make the sheet metal under the condition of not to break the billet occurred plastic deformation, made into the required shape and size of the workpiece. Separation process is also called the blanking, and its purpose is to make the stamping parts along the predetermined good overview line separation from sheet metal, at the same time guarantee the separation section of the character of the request. In actual production, is often a variety of process integrated operating together in a workpiece. Cutting, straight, shear, spinning, replace the stamping process is often used. Precision metal stamping parts mainly is the metal or nonmetal sheet, with the aid of the pressure of the press, through the stamping die stamping forming, it basically has the following features: precision metal stamping parts stamping with the surface of the sheet metal and denotation to stamping has great influence on the quality of the waste, cried out to stamping data roughly, uniform thickness; Surface light, no spots, no scar, no scratch, no surface crack, etc. ; Obey the uniform strength, without taste preference; Even unfold. angry rate is high; Showed low; Work hardening low; Stamping parts with high dimensional accuracy, with the module size uniformity, good interchangeability. Don't need to be further mechanical processing can satisfy the requirement of the general assembly and use; Stamping is in the material under the premise of consumption is not big, the impact compression, with the parts of lightweight, good stiffness, and made the sheet metal by plastic deformation, metal lost to improve the internal structure of the layout of the strength of stamping parts forward; Stamping parts in stamping process, due to the material inside is not affected by crushing, so have good inner quality, outside enjoying smooth good-looking, this inner spray paint, electroplating, phosphating and also the inner disposal to supply any conditions.
