Temper mill with roll bending and shifting functions

Abstract

The invention belongs to the technical field of forming and discloses a temper mill with the roll bending and shifting functions. The temper mill mainly comprises a stand frame, a working roll changing device, a back-up roll changing device, a main transmission gear, upper and lower working roll fittings, a thickness control device, upper and lower back-up roll fittings and a rolling line elevation adjusting device. A working roll shifting and bending device is inlaid in a housing window of the temper mill. Positive and negative roll bending cylinder bodies at the transmission side and a roll shifting cylinder body are integrated on a bending and shifting integrated block. A piston rod of the roll shifting cylinder is fixedly mounted on a housing by an E-shaped block. Positive and negative roll bending cylinders at the operating side are integrated on a roll bending integrated block, without roll shifting cylinders. The integrated blocks at the transmission side and the operating side are connected together by a roll changing rail in the housing of the temper mill to form the working roll shifting and bending device. The invention ensures the means of adjusting the roll gaps to be more flexible, can prolong the service life of the working roll, realize rapid roll changing, shorten roll changing time and reduce the production cost. The invention can be widely applied to strip temper mills.

Description

Technical field: [0001] The invention belongs to the technical field of molding, and discloses a tempering machine, in particular, a tempering machine with the function of bending and shifting rolls. Background technique [0002] The main function of the tempering machine is to improve the shape of the steel plate and eliminate the local thickness tolerance, so that the steel plate has a good shape and better surface quality; in addition, the use of a small reduction can also eliminate the yield platform, Improve the deep drawing performance of steel plate. At present, in the skin pass mill with the function of work roll shifting, the roll bending and roll shifting are divided into two parts. The bending part is arranged in the frame of the skin pass mill, and the roll shifting cylinder is an external hydraulic cylinder, which is arranged on the transmission side. The pin shaft is connected with the bending roll part, which occupies a large space on the transmission side, a...

Problems solved by technology

[0003] When replacing the working rolls, the mode of hooking out the old rolls on the operating side, moving them sideways, and then pushing the new rolls in requires a traverse machine for the working rolls, which requires high investment and maintenance costs, and takes a long time to change the rolls. Coil and leveling mode cannot be quickly switched. When the coil is divided, because the distance between the lower surface of the upper work roll and the upper surface of the lower work roll is too small, if the strip passes between the upper and lower work rolls, the work roll will be scratched surface, seriously affecting the service life of work rolls
