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?
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
Rigid force, 1000N-3000N, damage to the guide rail of machine tool transmission mechanism, seriously damage the accuracy and life of machine tools.
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
A movable wire plate, made of the same fixed wire plate, for relative reciprocating motion. Roll forming is the design of different structures on the plate rolling on the workpiece. Roll out all kinds of thread, convex ring, knurling, end chamfering, groove with different width and thickness as well as other required shapes.
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.
