Numerical simulation study of steel wire winding split ultra-high pressure die

Abstract

In this paper, a new type of large-cavity two-anvil ultra-high pressure die structure is proposed to solve the problem that the large-scale of the two-anvil ultra-high pressure die is limited by the difficulty in machining the large-size tungsten carbide. The die is mainly composed of an internal split cylinder with an inner cone and its support ring and the external steel wire winding layer. The stress distribution and cavity dimensional stability of the split cylinder are studied by using the finite element method and compared with those of the integral cylinder. This suggests that although the cavity-dimensional stability of the split ultra-high pressure die is reduced, the split ultra-high pressure die has greater advantages in improving the pressure-bearing capacity, processing, and manufacturing.
