Composite Plate Rolling With Recessed Rollers to Prevent Burrs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The metal composite rolling process often results in flashings and burrs due to inaccurate width dimensions and excessive friction, leading to additional production costs and defects in the composite workpiece.
Innovation Solution
A method involving placing a first plate and a second plate in a recess around a roller, with the harder plate having striations to enhance bonding, and controlling rollers to rotate and combine them into a composite plate, while heating and subjecting it to solid solution and aging treatments to improve structural strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If side rollers are pressed tightly against working rollers, then width dimension control is improved, but friction increases causing damage to the rolling device
Solution Approach 1:
A recess structure is introduced as an intermediary element between the side rollers and working rollers. The recess provides a controlled contact zone that limits the interaction area, thereby reducing friction and wear on the rolling device while maintaining effective width control of the composite plate during the rolling process.
Solution Approach 2:
The recess is designed with specific local geometric properties (depth, width, position) that create a localized contact zone. This local quality modification allows the side rollers to exert control force precisely where needed for width dimension control, while the rest of the roller surfaces remain free from excessive friction and damage.
2Manufacturing precision
If side rollers are pressed tightly against working rollers, then width dimension control is improved, but flashings and burrs still occur
Solution Approach 1:
The recess acts as an intermediary structure that mediates between the side rollers and the composite plate. It provides a controlled containment zone that prevents excessive material flow to the sides, thereby eliminating flashings and burrs while maintaining precise width control through the recess geometry.
Solution Approach 2:
The recess structure is prepared in advance on the working rollers before the rolling process begins. This preliminary action creates a pre-defined boundary that guides the composite plate material during rolling, preventing flashings and burrs from forming in the first place rather than correcting them afterward.
3Strength
If rolling pressure is increased to prevent flashings and burrs, then bonding strength is improved, but dimensional inconstancy causes defects
Solution Approach 1:
The recess creates a localized zone where rolling pressure is concentrated and controlled. This local quality modification allows high pressure to be applied precisely where needed for bonding, while the recess geometry simultaneously constrains dimensional variations, preventing flashings and burrs even when processing materials with dimensional inconstancy.

AI summary
The present invention relates to the technical field of material processing and provides a method for making a metal material composite, including: contacting a first surface of a first plate with a second surface of a second plate; placing the first plate and the second plate in a recess in a circumferential direction of a first roller such that a third surface of the second plate contacts a bottom wall of the recess in a circumferential, the third surface being opposite the second surface, the first plate having a greater hardness than the second plate; and controlling a first roller and a second roller to rotate, thereby rolling to combine the first plate and the second plate into a composite plate, where a fourth surface of the first plate contacts a surface of the second roller and the fourth surface is opposite the first surface during the rolling. According to the method for making a metal material composite in the present invention, flashings and burr on the side edges of a composite plate are avoided by placing the first plate and the second plate in a recess for machining.
