Reduction Forming of stainless steel eccentric reducer processing technology

　　There should be no cracks and heavy skin in the appearance of the stainless steel eccentric reducer, and the wall thickness should be greater than the wall thickness of the large diameter end section. The roundness of the stainless steel eccentric reducer should not be greater than 1% of the outer diameter of the corresponding end, and the allowable deviation is 1%. The centerline of the two ends of the Large-Caliber Customized Stainless Steel Eccentric Reducer should coincide with the allowable deviation of its eccentricity.

　　The shrinkage forming process of stainless steel eccentric reducer is to put the tube blank with the same diameter as the big end of the tube into the forming die, and by pressing along the axial direction of the tube blank, the metal moves along the die cavity and shrinks to form. There should be no cracks and heavy skin on the outside of the pipe, and the wall thickness of the pipe should be greater than that of the large diameter end section. The center line at both ends of the pipe should coincide with the allowable deviation of its eccentricity. According to the size of diameter change of stainless steel eccentric reducer, it can be divided into one pressing forming or multiple pressing forming.

　　Stamping Method of stainless steel eccentric reducer

　　Because the die ensures the dimension and shape accuracy of stamping parts, and generally does not destroy the surface quality of stamping parts, and the life of the die is generally longer, the stamping quality is not disorderly, good interchangeability.

　　Stamping is a kind of material-saving and energy-saving processing method, because it has no chips and debris, less material consumption and no need for other heating equipment. The cost of stamping parts is low.
