Auxiliary maintenance device and method for tandem cold rolling mill

Abstract

The invention discloses an auxiliary maintenance device and method for a tandem cold mill. The auxiliary maintenance device comprises a cart, wherein a vertical supporting plate is fixed on one side of the upper end of the cart; a first connecting plate is fixed at the upper part of one side end of the vertical supporting plate; one side end of the first connecting plate is rotationally connectedwith a vertical platform plate; a first dovetail groove is formed in the end, facing the vertical supporting plate, of the vertical platform plate; a first dovetail block is arranged in the first dovetail groove and connected with the first dovetail groove in a sliding manner; a second connecting plate is fixed at one side end of the first dovetail block; one side end of the second connecting plate is rotationally connected with a supporting rod; a first limiting bolt hole is formed in the vertical platform plate; a connecting block is fixed at the upper part of one side end of the supportingrod and rotationally connected with a third connecting plate; a second dovetail block is fixed at one side end of the third connecting plate; and a second dovetail groove is formed in the vertical supporting plate. Through the auxiliary maintenance device, a maintainer is allowed to ascend to the vertical platform plate through a ladder to maintain the upper part of the tandem cold mill, so that the maintenance is more convenient; and a water pump sprays out water from a water tank through a water spray nozzle to clean components and parts, so that the auxiliary maintenance device has a very high application value.

Description

Technical field[0001]The present invention relates to the field of cold rolling mills, and specifically, a cold coiling machine auxiliary maintenance device and method.Background technique[0002]Cold and rolling refers to the use of a hot rolled steel roll as a raw material, and the oxidized skin is washed. Its finished product is a rolled hard roll. Due to the cold-modified coldness hardening of continuous cold deformation, the hardness of the rolled hard roll is rising, the resilience decreases, so the stamping performance will deteriorate, and can only be used for simple-deformed parts. Cold and rolled steel production includes: acid washing, cold rolling, degreasing, annealing, flat, finishing, coating, etc., is the highest production sector in the field of production and automation control, representing the highest rolling technology. Level. Cold rolled steel roll must be finished after annealing, including cut, tail, cutting, flat, flat, heavy roll or longitudinal cutting board...

AI Technical Summary

Problems solved by technology

[0003] When the existing tandem cold rolling mill is being maintained, maintenance personnel are sometimes required to climb up to the upper end of the tandem cold rolling mill. However, due to its large size, it is not easy to climb up. Usually, other large-scale mechanical assistance is used, and the large-scale mechanical movement is not easy. Convenient, cumbersome to use, not conducive to frequent use, and simple handling of parts during maintenance, and no convenient tools
