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?: Rolling process is a kind of pressure finishing, which is a kind of cold plastic characteristic of metal under normal condition.

Q: Improvement in rolling forming process: It is difficult to control the rolling process and can cause waste easily.

Q: Introduction of roll forming process: Roll forming began around 1960s in europe. Because of roll forming, the working model has the advantages of high production efficiency, saving material and increasing product strength.

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: 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 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.
