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: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: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: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: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?: According to my experience, there should be a problem with the boot encoder (also known as the digital wheel). Thank you. I hope I can help you.

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.

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.
