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
Can not meet the slender rod, thin-walled tubes and other rigid parts of the processing.
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: 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
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
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.
