Function and use instructions of the pipe bending machine mandrel

When the small bending cordrel away from the cut point and in the back position, will not be able to stretch data on the outside of the bend, so the position of the cordrel back provoked a large rebound, may make the complete Angle smaller and may increase the radius, if the radius becomes larger, can push to the cut point. Adjust the settings of the cordurol. If the pipe is constantly broken, it is clarified that the data is really too hard, too hard data can not be fully stretched, can be used to complete the annealed tube to deal with the problem. The so-called rebound control refers to the possibility of changing the bend back to the original shape after molding. The rebound will reduce or increase the bending degree according to the bending radius of the bend. The smaller the bending degree, the smaller the rebound will be. The rebound is affected by the position and pressure. Small pipe bending machine pipe will have twisted or wrinkled bend, showing the reason for this may be excellent data, so can not shrink the inner diameter when bending, showing this phenomenon, can be inserted into the cordrel to deal with.
