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?: Maybe there is something wrong with that roller. It rolls out of the wrong angle and the size will be out of order.

Q: What is rolling forming processing?: A special rolling tool is used to exert certain pressure on the surface of the workpiece so as to make the surface metal flow.

Q: Improvement in rolling forming process: The rolling will produce a hardening layer on the surface of the workpiece. This layer has obvious delamination phenomenon with the internal material, which is easy to cause the surface layer to fall off;

Q: Introduction of roll forming process: With the progress of technology and the development of production, more and more attention has been paid to the roll forming process.

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?: Non bonding wear of rolled material (especially stainless steel strip, etc.)

Q: What is the surface rolling forming machine process?: The rolling process using metal at room temperature, cold plastic characteristic, through the rolling tool is the rolling tool to put some pressure on the metal surface, so that the workpiece surface by plastic deformation, the height to the lower tissue slip, the surface roughness decreased.

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: Rolling process is a cold forging process, which can be used for rolling and forming a lot of materials. Among them, low carbon steel is a material commonly used in rolling forming, and non-ferrous metal is more suitable for roll forming.
