I. Cold rolling Mill

It's also called cold pilger mill, is applied to roll carbon steel, stainless steel, non-ferrous metal, rare metal and alloy steel in cold condition. Its products have been widely used in such industries as metallurgy, automotive industry, bearing manufacturing, oil machinery manufacturing and so on. All of the out purchases that we used are famous brand in our market, which is one of the main reason of our good machine quality. We have various kinds and complete spec. Our machine widely export to countries as India, Iran, Korea etc.

Q: A roll forming machine, rolling out of the length is always not up to a fixed size, not too small, that is, more than that, what is the cause?: Yes, the width of the bearing plate can be a deviation from the length.

Q: What is rolling forming processing?: Rolling process is a kind of pressure finishing, which is a kind of cold plastic characteristic of metal under normal condition.

Q: Improvement in rolling forming process: Rigid force, 1000N-3000N, damage to the guide rail of machine tool transmission mechanism, seriously damage the accuracy and life of machine tools.

Q: Introduction of roll forming process: Roll forming began around 1960s in europe. Because of roll forming, the working model has the advantages of high production efficiency, saving material and increasing product strength.

Q: What kind of material and what heat treatment are used for pressing roller (molding, feeding, cutting force, heavy load, heavy load) of sheet steel rolling machine?: Use 40Cr or 20Cr, Cr12.Cr12MoV, quenching and tempering treatment, think of hardness, high point, carburizing, nitriding, and consider adding lubrication device to extend its service life

Q: What is the surface rolling forming machine process?: Due to the rolling surface of metal plastic deformation, so that the surface microstructure of cold hardening and grain refinement, forming a dense fibrous, and the formation of residual stress, hardness and strength, so as to improve the surface wear resistance, corrosion resistance and compliance.

Q: Process mould for rolling forming process: A movable wire plate, made of the same fixed wire plate, for relative reciprocating motion. Roll forming is the design of different structures on the plate rolling on the workpiece. Roll out all kinds of thread, convex ring, knurling, end chamfering, groove with different width and thickness as well as other required shapes.

Q: Material and equipment for roll forming process: The most common type of roll forming is reciprocating flat wire twisting machine. Therefore, for the manufacturers of cold heading machines and screw rolling mills, the design of rolling dies is only a matter of design.
