Abstract
Sheet hydroforming is one type of hydroforming and has many advantages.In this paper,the sheet hydroforming processs development has been reviewed and the basic principles and features are introduced and discussed.Some new ideas about the equipment and process are summarized.The prospects about sheet hydroforming are estimated.Based on the existed sheet hydroforming technologies,a new method,named as hydromechanical deep drawing without draw die is proposed and developed.By means of experiment and numerical simulation,this process has been analyzed and studied,and good results have been obtained.This proves that the process is reliable and can be used to form the parts with better quality and higher drawing ratio.
