AI Technical Summary

Technical Problem

When the existing four-roll cold rolling mills work with high hardness, the roller pressing wheels are prone to excessive stress and misalignment, resulting in large tolerances of finished products and low pass rate.

Method used

A four-roll cold rolling mill for processing 3D curved surface imitation materials was designed, using a combination of two roller presses and two auxiliary wheels. The rim surface of the roller presses is divided into large column sections and small column sections. The auxiliary wheel and the radial surface of the roller presses are rolling and fitted to prevent the roller presses from being misaligned.

Benefits of technology

Through the abutment limit of the auxiliary wheel, the misalignment of the roller pressing wheel is avoided, the accuracy of material processing is improved, the tolerance of the finished product is reduced, and the pass rate is improved.

Abstract

The utility model belongs to the technical field of cold-rolling mills, and particularly relates to a four-roller cold-rolling mill for machining titanium 3D curved surface profiling materials. Comprising a rolling wheel set and an auxiliary wheel set, the rolling wheel set comprises two rolling wheels, the auxiliary wheel set comprises two auxiliary wheels, the rim faces of the two rolling wheels are divided into large column sections and small column sections in the axial direction, the radial faces of the two sides of the two rolling wheels are located on the same horizontal plane, and the large column sections and the small column sections are matched in a staggered mode. A rolling area is formed between the large column section and the small column section on the mutually staggered and matched sides of the two rolling wheels, the rim surfaces of the two auxiliary wheels are respectively attached to the radial surfaces of the two rolling wheels in a rolling manner, and the auxiliary wheels are used for abutting and limiting the rolling wheels; when high-hardness materials are machined, the rolling wheels can be prevented from being stressed and misplaced, and the qualification rate of finished products is increased.
