The role and significance of bar and tube straightening machine
- Dec 06, 2018 -

The bar and tube straightening machine is mainly used for the straightening treatment of metal pipes and bars, and straightening is an important part of finishing. In order to improve the quality of metal pipe and bar products, in the finishing process, it is usually necessary to straighten, polish, chamfer, internal and external flaw detection, surface peeling, grinding, etc. to eliminate or detect defects, so that the product meets product standards and User requirements, while greatly increasing the added value of the product.


Therefore, the pipe straightening machine is also one of the key equipments in the finishing process of these metal pipe fittings. At the same time, with the increasing demand for high-precision pipes by nuclear power, aerospace and military, the importance of straightening machines in the finishing process of pipe bars is increasingly prominent. In order to adapt to the development of the production field, many new straightening machines have been developed.


In the process of straightening the bar and tube straightening machine, the main principle is to use the straightening rollers which are inclined up and down to be staggered, so that the bar rotates under the friction of the straightening roller to produce plastic bending deformation to achieve correction. Straight, significantly improves the straightness of the head and tail and reduces the ovality of the pipe or bar.
