Stainless steel eccentric reducer should not have crack, double skin appearance, wall thickness should be greater than the big diameter end section of the wall thickness. Roundness of stainless steel eccentric reducer should not be greater than 1% of the corresponding end diameter, and the allowable deviation of plus or minus 3 mm; Centerline should overlap on both ends of the stainless steel concentric reducer, the eccentric value allowable deviation is + / – 5 mm.
Reducing forming technology of stainless steel reducer is with eccentric head big end diameter equal to the size of the pipe into the forming mould, through along the axial direction of tube billet, shrink along the cavity movement and metal forming. Stainless steel reducer should not have crack, double skin appearance, wall thickness should be greater than the big diameter end section of the wall thickness. Centerline should overlap on both ends of the stainless steel reducer, the eccentric value allowable deviation is + / – 5 mm. According to the size of the stainless steel reducer, pided into the one of pressing or more press forming.
Stainless steel reducer stamping method
(1) because when stamping die to ensure the stamping precision of size and shape, and generally does not destroy the surface of the stamping parts quality, and the life of the mould are long, so the quality of stamping not disorderly, good compatibility, has the characteristics of “the same”.
(2) stamping, generally no chip broken material naturally, less material consumption, and do not need other heating equipment, it is a kind of material, machining method of energy saving, stamping parts of the capital is low.
