Description

Technical Field

[0001] The utility model relates to a straightening roller device for a straightening machine. Background Art

[0002] A straightening machine is a device used to straighten metal profiles, bars, pipes, wires, etc. The straightening machine uses straightening rollers to extrude bars to change their straightness. There are generally two rows of straightening rollers with varying numbers. There are also two-roller straightening machines that rely on the angle changes of the two rollers to straighten materials of different diameters. The main types include pressure straightening machines, balanced roller straightening machines, shoe roller straightening machines, rotary reverse bending straightening machines, and so on.

[0003] The existing straightening machine sleeve roller is in a fixed connection state in the straightening machine. When the sleeve roller is damaged and needs to be replaced, the operation is rather cumbersome and multiple components and parts need to be removed to replace and maintain the sleeve roller.
