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?: 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 utility model has the advantages of short service life, easy damage and high comprehensive use cost.

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?: 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?: Different from cutting, mirror rolling is a kind of plastic processing. Not only is the rolling workpiece surface roughness moment can reach Ry0.1-0.8 m, and the wear resistance of the surface hardening process has been improved at the same time fatigue strength also increased 30% advantages in cutting can not get.

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 molding is usually through upsetting a blank cold heading machine, thread rolling machine rolling after processed. The equipment for thread rolling and rolling forming includes various reciprocating flat rolling machines, planetary wire rolling machines, two cylindrical roller spinning machines and three cylindrical roller spinning machines.
