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:Improvement in rolling forming process: The utility model has the advantages of short service life, easy damage and high comprehensive use cost.

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: Not only threaded fasteners industry applications, automobiles, bicycles and other industrial sectors also use rolling forming process, processing complex shapes of parts.

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:Process mould for rolling forming process: Rolling forming is more complicated and requires higher than rolling thread. The die design is based on the different shapes of the workpiece, the design of the rolling plate into a cross section or a few sections, can use synchronous type; also can use grading type.

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