In the composite drawing of the production, is essential to begin a process, the major manufacturers begin using artificial methods so that the beginning part of Shouli Bu all, the composite drawing of the molding easy for the two stickers inside and outside of not close, A direct impact on their production efficiency and product quality. This paper is mainly directed against the cold of the beginning of the process requirements, design technology to meet the requirements of the mechanical devices, devices meet the specifications Φ20-Φ60, pipe wall thickness of 0.5 mm, possession of 1.5 mm, beginning length of not more than 200 mm, Forming a first time. Transmission System using the device Gear, and then through the cam will rotate into translation and promote mold of suppressing the first, the installation of every six minutes beginning, a beginning to take three seconds, three seconds interval beginning, molding After the beginning of some of the uniform, a solid closer, a bottle-
