For stainless steel reducer without mould design study of the drawing process

Stainless steel reducer without die drawing process is a kind of metal flow stress vary with temperature and change the nature of the implementation of flexible plastic processing technology, is a kind of high precision, high efficiency and low energy consumption, no pollution, no mold, no friction, no lubrication nearly plastic forming technology. Different materials tensile properties. Tensile rate limits the proportion of blank diameter and diameter of stamping. Control control from 2.1 to 2.2 and carbon steel stainless steel material in 2.15 to 2.5.
Stainless steel material to deep drawing for the second time after deep drawing, but different from carbon steel materials, stainless steel usually cannot be equal to the first degree of stretching, unless after heat treatment. Stainless steel reducer material requirements of devices is the power of the carbon steel material 1 to 2 times.
Stainless steel reducer
Generally best deep drawing using double acting hydraulic equipment. On the tensile deformation of stainless steel reducer without wall thickness change has carried on the experimental study, when there is no mould drawing stainless steel reducer is analyzed the influence factors of wall thickness change and the influence law. Determine the stainless steel reducer without mold wall thickness changes when stretching empirical formula.
