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.
