| Abstract: | Air-conditioner＇s brass triple valve has complex geometry and high demand of mechanical properlies, is produced in large quantities. As a classical technology, hot forging has some disadvantages： low coefficient of material usage, considerable amount of post machining and low production efficiency. This paper represents a new technology, warm extrusion method to replace the classical hot forging technologies. An FEM model of warm extrusion process has been established by u sing nonlinear finite element analysis DEFORM 3DTM software, mechanism of plastic deformation and the influences of tech nology parameters on the quality of triple valve are investigated. And then, the reasonable forming parameters for this warm extrusion process to form Triple Valve are obtained. |
