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?: Generally speaking, to consider the use of rollers in the requirements, including: 1., good wear resistance, 2. toughness, 3., high hardness, 4. hardened layer (easy to wear after repeated repair)

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: Press forming is an advanced processing technology, and its remarkable characteristics have been paid attention to by the automobile industry at home and abroad.

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.
