A roll set capable of quickly replacing wrinkle-proof rolls

Abstract

The invention relates to a roller set with an anti-wrinkling roller capable of being replaced rapidly. The roller set with the anti-wrinkling roller capable of being replaced rapidly comprises the anti-wrinkling roller, a supporting roller, a supporting roller bearing seat and an anti-wrinkling roller bearing seat. The anti-wrinkling roller is assembled on the anti-wrinkling roller bearing seat. The supporting roller is assembled on the supporting roller bearing seat. Hanging bases provided with openings are arranged on the two sides of the supporting roller bearing seat. Eye bolts are arranged in the hanging bases. Disc springs are installed on the eye bolts. The tops of the disc springs are fixed through nuts. A slideway provided with positioning key grooves is arranged below the supporting roller bearing seat. Positioning keys are arranged on the two sides of the anti-wrinkling roller bearing seat. The positioning keys are matched with the positioning key grooves below the supporting roller bearing seat. Hinge pin holes are formed in the top of the anti-wrinkling roller bearing seat. The lower portions of the eye bolts are connected with the hinge pin holes through pins. No roller replacement equipment of a complicated structure is needed when the anti-wrinkling roller is replaced, the time is greatly shortened, the maintenance time is shortened, and the utilization rate of the set is improved; the anti-wrinkling roller can be replaced independently, the number of spare parts of the supporting roller is reduced, and fund occupation of the spare parts is reduced; manpower is saved, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the field of metallurgical equipment, in particular to an anti-wrinkle roller set, and more particularly to a roll set capable of rapidly replacing anti-wrinkle rolls. Background technique [0002] In the process of cold rolling production, an anti-wrinkle roller set is set at the outlet of the pickling uncoiler, and the hot-rolled strip is bent by pressing the roll set to remove the cross-folding of the hot-rolled strip. In order to ensure its use effect, the design diameter of the anti-wrinkle roller is usually small, and a support roller is required as the support of the anti-wrinkle roller to avoid the bending and deformation of the anti-wrinkle roller. The anti-wrinkle roller has a large workload, wears quickly and needs to be replaced regularly, while the support roller has a large diameter and does not directly contact the strip, and its service life is much longer than that of the anti-wrinkle roller. The traditional t...

AI Technical Summary

Problems solved by technology

It takes a long time to replace, requires complex roll changing equipment, and needs to prepare the same number of support roll spare parts as the anti-wrinkle roll spare parts, the cost of spare parts is high, more manpower and working hours are required for replacement, and the economic benefit is poor
