Abstract：

The strap wheel is a sleeve punch part with two V-shape slots,and it is shaped by hydraulic pressure method.The technologic property and working procedure of the strap wheel was analyzed and the structure of the die,the character and working principle of the die were described.The plate of the die was mainly composed of floatable upper and low rings.The wedge system and three-part ring holder controlled the radial movement of the rings.When the upper ring impacted the part,it made the vertical movement with the part.So the quality of the part was.ensured The structure of the die was compact and the efficiency was promoted.
