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?: Yes, the width of the bearing plate can be a deviation from the length.

Q: What is rolling forming processing?: Ironing the surface of the workpiece with a raised micro wave crest to fill the concave micro troughs, thus changing the distribution of the peaks on the surface, and obtaining smaller surface roughness values.

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: 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: 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: 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.
