Chinese Summary
Cold-drawn composite pipe production, the major manufacturers is the beginning of artificial means, low efficiency and high quality. This paper is mainly directed against the cold of the beginning of the basic requirements, design technology to meet the requirements of the mechanical devices to 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, a first time Molding. This device used gear drive, and then through the cam will rotate into translation, driven composite drawing tube mold pressure to achieve technological requirements. So as to enhance the composite drawing of the production efficiency and quality.

Key words: composite pipe; beginning; gear; cam; rotation; translation
