Abstract

Abstract

Due to the machining challenge of high-quality cemented carbide, ultra-high pressure devices are always limited on scale. In our work, a new type of wire wound and split ultra-high pressure die with two-anvil was proposed to try to overcome this limitation. The die is mainly composed of internal split cylinder and external prestressed steel wire. On the basis of the mechanical modeling and via the finite element software, the equal tension winding die was analyzed and the split pressure die as well as steel wire winding layer were studied. The results show that the maximum equivalent stress appears on the inner wall of the pressure die cavity after loading; the dimensional stability of pressure die cavity is proportional to the number of layers of wire winding and the diameter of the wire. The axial stress of the wire in the winding layer is inversely proportional to the diameter of the wire but proportional to the number of layers of the wire.
