Combined type roller for rolling wave form corrugated composite boards

Abstract

The invention discloses a combined type roller for rolling wave form corrugated composite boards and belongs to the technical field of rollers. The combined type roller for rolling wave form corrugated composite board belts comprises a roller shaft, a roller shell, a spline, a flat key, a locking check ring and a screw. The combined type roller is structurally characterized in that an external spline is arranged on the roller shaft, an internal spline groove is formed in the roller shell, the roller shell is arranged on the roller shaft, the spline plays a role in positioning and is a rectangular spline, the outer surface of the roller shell is in a wave form corrugation shape, the metal composite board belts with wave form corrugation can be rapidly rolled, the contact area of a metallic matrix can be increased by using the wave form corrugation roller for making blanks, the combination strength of composite board interfaces can be enhanced, and the recombination rate of composite board interfaces can be increased; a step-shaped shaft shoulder is arranged at one end of the roller shaft and axially fixes the roller shell; and locking positioning, in the axial and radial directions of the roller shaft, of the other end of the roller shell is achieved through the cooperation of the flat key, the locking check ring and the screw. According to the combined type roller, the centring precision of the roller is high, the stability of centring is extremely high, axial roller shifting is prevented, the roller shell can be rapidly dismounted, and the assembling period of the combined type roller is shortened.

Problems solved by technology

[0002] At present, metal clad slabs composed of different properties have been widely used in metallurgy, mining, chemical industry, aerospace and other industrial fields. Metal composite materials give full play to the respective advantages of component materials. For rolling equipment, flat-roll mills are mostly used to roll composite slabs. The composite strips rolled by flat-roll mills have low bonding strength and are easy to tear;

[0003] Furthermore, there are mainly two types of roll devices at present: one is to form a certain thickness of wear-resistant material on the surface of the roll body through casting, surfacing, laser treatment, etc., and the other is to compare the impact resistance, shear resistance, and bending resistance of the roll. Well, the working layer uses an alloy roll ring made of wear-resistant materials, and the two are fixed in a certain way to form a combined roll; among them, the fixed methods used are different, and the production cycle will change accordingly. Solve the shortcomings of flat roll rolled composite strips such as easy cracking, low composite efficiency, and long production cycle, which cannot meet the needs of existing national production; therefore, a new rolling device for rolling composite strips is designed, which is effective Improve the bonding strength of the metal composite plate, increase the bonding force between the metals, facilitate disassembly and assembly, effectively avoid the defect of excessive stress concentration, shorten the processing and assembly cycle of the roll, and maximize the production efficiency
