Metal forming can not only form complicated shapes
but also promoting mechanical properties by utilizing the plasticity of metal materials.It can decrease the product the production cost by reducing the subsequent machining work.Metal forming which plays a great role in national economy is widely used in industries.The article analyze the processing craft principle and the technology of metal material extrusion forming by taking the sleeve spanner forming as the example.Then it elaborates technique analysis of metal material forming
the choice of craft plan
the working procedure design
the warm extrusion pressure computation
the press choice and the mold structure design etc.
