Classification of precision stamping parts processing, how much do you know?
Precision stamping by press and die for sheet, strip, pipe and profiles, such as external force, to produce plastic deformation or separation, to obtain the required shape and size of the workpiece forming method.
According to the different process conditions have different classification methods, stamping processing the following by dongguan precision electronic technology co. , LTD. Simple introduce what types of stamping process: a, divided according to workpiece finished product: precision stamping process according to the workpiece can be roughly divided into separation process and finished product forming process (
And bending, deep drawing, forming)
Two kinds big.
Separation process is made in the process of stamping stampings and block along the contour line must be separated, at the same time, the quality of stamping parts separation section to satisfy certain requirements;
Stamping forming technology is to make the blank plastic deformation under the condition of not to undermine, and translating the required finished product shape, but also should satisfy the requirement of dimensional tolerance, etc.
Second, according to the temperature at which the stamping division: the temperature at which the precision stamping press stamping is divided with cold stamping and hot stamping in two ways.
Depending on the strength of the material, plastic, thickness, deformation degree and equipment capacity, etc. , at the same time, should consider the raw material heat treatment state and the final conditions of use.
Cold stamping processing of metal at room temperature, thickness of generally applicable to small billet.
Advantages as without heating, no scale and good surface quality, convenient operation and low cost.
Defect is have work hardening phenomenon, serious when lose metal further deformation.
Cold stamping in most cases need to use stamping oil, to improve the process and requirements of billet thickness and the fluctuation range is small, smooth surface, no spots, no scratches, etc.
Hot stamping will be heated to a certain temperature range of metal stamping processing method.
Advantages for can eliminate internal stress, avoid work hardening, increase the plastic material, reduce the deformation resistance, reduce the power consumption of the equipment.
Precision stamping front with customers to develop, strictly make mold design review and examination, improve terminal shrapnel terminal product development success rate and the efficiency of production, the rationality.
From mold design production mold.
Achieve agreed delivery quantity, the mould fees.
Stamping production with high efficiency, saving processing costs.
