Abstract

As to high pressure bulging of spiral stator metal tube with equal thickness rubber bushing, the paper proposing a method of internal and external high pressure bulging which charactered by the diameter of the rough tube is between the major diameter and the minor diameter of the spiral surface of the tube. It formes the groove part of the tube and the convex part of the tube by external high pressure bulge and internal high pressure bulge respectively, so it reduces the limit height of expansion to the thickness and geometric size of the workpiece. The simulation of bulging process is carried out by using finite element software, reveals the forced flow law of metal pipe under the contact of uniform high pressure and regular spiral surface and verifies the feasibility of internal and external high pressure bulging process, this method can greatly reduce the pressure of bulging system.
