Description

Online straightening device for stainless steel pipe

Technical Field

The utility model relates to a stainless steel pipe technical field, more specifically are an online straightener of stainless steel pipe.

Background

The stainless steel pipe is a hollow long-strip round steel material, and is mainly widely used for industrial conveying pipelines, mechanical structural parts and the like of petroleum, chemical industry, medical treatment, food, light industry, mechanical instruments and the like. In addition, since the steel sheet is light in weight when it is bent and has the same torsional strength, it is widely used for manufacturing machine parts and engineering structures. The hardness of the material is most widely used in the standard of stainless steel pipes, such as household utensils and kitchenware, and is often expressed by the diameter of an indentation, so that the material is visual and convenient. However, the rockwell hardness test of stainless steel tubes is the same as the brinell hardness test, and is an indentation test method, which is not applicable to steel tubes made of harder or thinner steel materials. Except that it is a measure of the depth of the indentation. The rockwell hardness test is currently a widely used method, with HRC being used next to brinell hardness HB in steel pipe standards. The Rockwell hardness can be applied to the measurement of metal materials from extremely soft to extremely hard, which makes up the defects of the Brinell method, is simpler and more convenient than the Brinell method, and can directly read the hardness value from the dial of a hardness machine. However, the hardness value is not as accurate as that of the Brinell method because of small indentation, and the Vickers hardness test of the stainless steel tube is also an indentation test method and can be used for measuring the hardness of a very thin metal material and a surface layer. It has the main advantages of the Brinell and Rockwell processes, but overcomes the basic disadvantages, but is not as simple as the Rockwell process, and the Vickers process is rarely used in the steel pipe standard.

At present, the following problems exist in the straightening process of the stainless steel pipe: 1. manual straightening is mostly adopted in the straightening process of the stainless steel tube cabinet, so that the labor intensity is high; 2. the existing straightening device can only straighten steel pipes of one type in the straightening process, and the traditional straightening device is large in size and complex in structure. Therefore, a new technical solution needs to be provided.
