冷滚压钢管缩口工艺及工具设计

提出了一种简易的钢管缩口工艺实施方案,即利用闲置的旧车床,采用冷滚压法实现钢管的端部缩径;介绍了实现该工艺所需的缩口工具的设计与制造方法。实际应用表明,冷滚压钢管缩口工艺简易可行,缩口工具装卸方便,经缩口的钢管变形均匀。

Cold-rolling Process and Tools for Pointing of Steel Tube

Proposed in the essay is an implementing scheme of a simple and easy cold-rolling process for pointing of the steel tube. The scheme involves using some lathe in idle to point end of the steel tube with the cold-rolling process. Presented in the paper are the design and manufacturing methods for the operation tools as used for the said process. The actual application result shows that the cold-rolling process is simple, and easy to be performed, while the operation tools are convenient for mounting and dismounting. And the steel tube as pointed with this process is just subjected to uniform deformation.
