No mold design of the drawing process for stainless steel tee

Stainless steel tee of non die drawing process is a use of metal flow stress with temperature changes in the nature and the realization of flexible plastic processing technology, is a kind of high precision, high efficiency, low energy consumption, no pollution, no mold, no friction, no lubrication near net forming technology. Different tensile properties of different materials. The limit of the tensile rate is the ratio between the blank diameter and the diameter of the punch. Three stainless steel material control in 2.1 to 2.2 and carbon steel control in 2.15 to 2.5.

Three stainless steel material can be second times in deep drawing deep drawing, but unlike carbon steel, three stainless steel material is usually not the same degree of tension and the first time after the heat treatment, unless. Three stainless steel material requirements equipment strength is 1 to 2 times of carbon steel equipment.
Three stainless steel
In general, deep drawing by double acting hydraulic equipment. On the three stainless steel in dieless tensile deformation of wall thickness were studied, analyzed the influence factors and influence laws of three stainless steel in dieless drawing of wall thickness variation. The three stainless steel in dieless drawing wall thickness formula.
