Inclined corrugated combined rolling roller for rolling metal composite plate

Abstract

The invention discloses an inclined corrugated combined rolling roller for rolling a metal composite plate. The inclined corrugated combined rolling roller comprises a roller shaft, an inclined corrugated roller sleeve, a wedge key, a locking ring and a hydraulic locking nut. The inclined corrugated combined rolling roller is characterized in that inclined corrugation is machined on the outer surface of the roller sleeve, an axial included angle formed between the inclined corrugation and the rolling roller ranges from 10 degrees to 80 degrees, the corrugation height is 0.1-1.5 times of the thickness of the composite plate, the corrugation width is 3-20 times of the corrugation height, the roller sleeve is arranged on the exterior of the roller shaft, circumferential and unidirectional axial positioning of the roller sleeve is achieved through the wedge key, and the roller sleeve is axially fixed by one end of the roller shaft through a shaft shoulder and axially locked and fixed by the other end of the roller shaft through the hydraulic locking nut. According to the combined rolling roller, the fastening precision is improved, and through cooperation of the upper working face, the lower working face and the side face of the wedge key and a key groove of the roller shaft, axial uniform stressing is achieved, and axial roller shifting is avoided; by rolling an inclined corrugated metal composite plate strip with the combined rolling roller, the bonding strength of the composite plate strip can be improved, and the residual stress and the warping degree can be decreased.

Description

technical field [0001] The invention belongs to the technical field of rolls, and discloses an oblique corrugated combined roll for rolling metal composite plates, which is used for rolling metal composite plates. Background technique [0002] At present, clad plates composed of metals with different properties have been widely used in metallurgy, mining, chemical industry, aerospace and other industrial fields. Metal clad materials give full play to the respective advantages of component materials. Existing rolled metal clad mainly Rolling mill, and the roll is an important part of the rolling machine, use the pressure generated by a pair or a group of rolls to roll the metal composite plate blank, and a huge torque will be generated at this time, when the torque is overloaded and This will lead to a slight relative rotation of the roller shaft and the roller sleeve, which will easily deform the roller shaft or the roller sleeve or even damage or break it, resulting in a sh...

[0002] At present, clad plates composed of metals with different properties have been widely used in metallurgy, mining, chemical industry, aerospace and other industrial fields. Metal clad materials give full play to the respective advantages of component materials. Existing rolled metal clad mainly Rolling mill, and the roll is an important part of the rolling machine, use the pressure generated by a pair or a group of rolls to roll the metal composite plate blank, and a huge torque will be generated at this time, when the torque is overloaded and This will lead to a slight relative rotation of the roller shaft and the roller sleeve, which will easily deform the roller shaft or the roller sleeve or even damage or break it, resulting in a short service life of the roller shaft or the roller sleeve, increasing the frequency of roll replacement, and failing to meet the existing national production needs; Therefore, a new type of combined roll for rolling composite strip blanks is designed. For this reason, a new type of rolling device for rolling composite strip blanks is designed to effectively improve the bonding strength of metal composite panels and increase the intermetallic Excellent binding force, reduce the residual stress of the metal composite plate, and easy disassembly and assembly, shorten the processing and assembly cycle of the roll, and improve the production efficiency to the greatest extent
