Abstract
A novel high pressure device with a tangent split cylinder was investigated on the basis of the belt-type apparatus. The cylinder is split into several blocks and the dividing line is tangent to the inner hole. This structure of the cylinder can eliminate the tangential tensile stress due to the friction and squeeze each other on the contact surface between the divided bodies. In this paper, different split numbers of the cylinders were choosen to study the stress distribution and the pressure-bearing capacity, and compare them with the traditional belt-type die (BTD). Simulation results show that the more the number of divided bodies, the smaller the stress and the higher the pressure-bearing capacity. The experiments also indicate that the tangent split die can bear higher pressure than the BTD. The tangent split tungsten carbide cylinder has the advantages of easy manufacture, strong bearing capacity and replaceable performance.
