Bending technology of automatic double head pipe bender
2018/11/13 11:52:42
Automatic double head pipe bender plays an important role in industry. In industrial production, the pipe parts are straight and round pipes, but most of the accessories required by industrial production are not straight pipes, which need to be bent by pipe bender to meet various industrial production needs. The full-automatic pipe bender can not only bend the pipe, but also carry out it automatically, improve the production efficiency and reduce the labor cost.
How does the automatic double head pipe bender affect the geometry of the bending process?
The bending process of induction heating changes the geometry of the original section. In other words, if the section becomes slightly elliptical, the outer wall of the elbow will become thinner and the inner wall will become thicker. These changes should be taken into account when designing the dimensions of curved sections. According to the German standards and technical requirements, the calculation of elbow wall thickness to overcome internal pressure is the same as that of straight pipe. Compared with the straight pipe, the stress of the inner wall of the curved section and the stress of the outer wall of the main body. Therefore, the inner wall thickness of the curve section must increase by a value of B, while the outer wall thickness will decrease by a value. In the process of induction heating, the bending stress changes with the thickness of the bending section. In induction heating automatic pipe bender, the change of wall thickness depends on the ratio of bending radius to pipe outer diameter. After bending, the inner wall thickness increases to meet the requirements of high-pressure pipeline. On the other hand, the outer wall thickness decreases. Theoretically, this is not allowed. Therefore, the thickness of the designed steel pipe should be thickened according to the predetermined thickness reduction. Ovality may occur during bending. It is a function of the ratio of the bending radius (MR) to the outer diameter of the tube (a) and represents this functional relationship.
