AI Technical Summary
Existing seamless cold drawing equipment suffers from cumbersome mold installation and disassembly, poor positioning reliability, uneven lubrication, and low automation, resulting in uneven steel pipe wall thickness, out-of-tolerance dimensions, and easy mandrel jamming and wear during the cold drawing process.
A cold-drawn mounting structure with a blocking ring and blocking groove was designed. Combined with a laser collimator and hydraulic system, the mold can be accurately aligned. A multi-zone lubricating oil distribution and automatic cleaning and polishing device are adopted, and the automatic collection of metal chips and lubricating oil is integrated.
It improves the convenience and positioning accuracy of mold installation and disassembly, reduces friction and mandrel jamming, ensures uniform steel pipe wall thickness and surface finish, and enhances cold drawing quality and automation.
