厚壁长筒形零件冷挤压成形工艺的研究

Study on Cold Press Forming Progress of the Thick Wall Long Tube Parts

对厚壁长筒形零件采用冷挤压成形工艺进行了可行性分析，阐明了采用所设计的工艺方案和特殊模具，能有效地抑制不利因素影响，实现了厚壁长筒形零件（S62链条滚子）的冷挤压一次成形。

This paper studied the feasibility of cold press progress on the thick wall long tube parts, introduced the technology scheme and the special mould structure. which can restain the factors unfavoured, only once can the cold press on the thick wall long tube parts (562 rollers of chains) be completed successfully.
