Convenient-to-disassemble roller clamping connection device for rolling mill

Abstract

The invention relates to the field of rolling mills, in particular to a convenient-to-disassemble roller clamping connection device for a rolling mill. A positioning and clamping mechanism, a left andright opening mechanism, an auxiliary device, two double-layer cross-shaped guide sliding seats and rollers are included. According to the convenient-to-disassemble roller clamping connection devicefor the rolling mill, the rollers only need to be manually mounted on a feeding clamping seat through the auxiliary device; through combination of a fork-shaped lifter and a front-back pushing mechanism, the rollers are driven to move to the designated position to be replaced, the mode that the rollers are pulled out from the side face is replaced, dismounting and mounting are conducted synchronously, a large amount of time is saved for workers, and replacement for usage is achieved through roller seats on the clamping connection device; and the roller seats are automatically disassembled andassembled through combination of the auxiliary device and the clamping connection device, it is avoided that two roller seats need to be arranged on each roller, the equipment cost is reduced, the roller seats are alternately used in this way, the replaced roller seats can be overhauled by workers, and a good state is prepared for the next work.

Description

technical field [0001] The invention relates to the field of rolling mills, in particular to a snap joint for easily dismounting rolls in a rolling mill. Background technique [0002] Rolling mill is the equipment that realizes the metal rolling process. It generally refers to the equipment that completes the whole process of rolling material production. When another product needs to be produced, it is often necessary to replace the rolling mill. The fixed plate of the fixed plate is disassembled, and then the roll is pulled out from the side, and then the new roll is installed on the rolling mill. However, replacing the roll and the roll seat by pulling out the roll from the side often wastes a lot of time for the workers, and in order to facilitate the replacement of the roll Two roller seats are arranged on the top, but the cost of the roller seats is too high, therefore, the cost of the equipment is increased. [0003] my country's patent application number: CN2019103...
