Cold rolling and annealing protection device capable of adjusting thickness of cold-rolled aluminum plate

Abstract

The invention relates to the technical field of cold-rolled aluminum, and discloses a cold rolling and annealing protection device capable of adjusting the thickness of a cold-rolled aluminum plate. The cold rolling and annealing protection device comprises a shell, wherein transport wheels are rotationally connected to the interior of the shell; a box body is fixedly connected to the interior of each transport wheel; movable blocks are movably connected to the interior of each box body; the inner side of the shell is fixedly connected with sliding rails; push rods are connected to the inner sides of the sliding rails in a sliding mode; and cold rolling wheels are rotationally connected to the exteriors of the push rods. Under the interaction of all structures of the device, after an aluminum material enters the device, an operator determines the thickness of a cold-rolled aluminum plate through a contact I, the cold rolling wheels are enabled to carry out cold rolling on the aluminum material through rotating gears and the push rods, and telescopic rods can conduct annealing treatment on the aluminum material, so that the effects that the cold rolling thickness of the cold-rolled aluminum plate can be adjusted and the aluminum plate can be automatically annealed are achieved, the working efficiency is improved, and material waste is reduced.

Description

technical field [0001] The invention relates to the technical field of cold-rolled aluminum, in particular to a cold-rolled annealing protection device capable of adjusting the thickness of a cold-rolled aluminum plate. Background technique [0002] Cold rolling is to use hot-rolled aluminum coils as raw materials. After pickling to remove scale, cold rolling is carried out. The finished product is hard rolled coils. Due to cold hardening caused by continuous cold deformation, the strength, hardness, and toughness of hard rolled coils increase. The plastic index decreases, so the stamping performance will deteriorate, and it can only be used for parts with simple deformation. [0003] The current cold-rolling device can only cold-roll the aluminum plate with a certain thickness. If different thicknesses are required, the aluminum plate needs to be cold-rolled through different cold-rolling devices. In this way, the steel needs to be transported and positioned. If more time ...
