What safety matters should be paid attention to when bending a single head hydraulic pipe bending machine?


Single-head hydraulic pipe bending machine is relatively hot recently: when the general pipe diameter is 20mm and below, use a hand-pulled simmer. The pipe simmer should be selected according to the diameter of the pipe, and it should not be large or small. When the pipe is simmered, the pipe simmer is placed on the required tortuous part of the pipe (that is, the tortuous point), and the pipe is stepped on with the foot and the handle of the simmered pipe is pulled, and the pipe is slightly tortuous with a little force.
Then move the pipe simmer backward point by point and repeat the previous action until the back end of the tortuous part, so that the pipe gradually simmer the required tortuous radius and tortuous view point.
When the pipe diameter is 25mm or above, the hydraulic pipe simmer should be used. The mold should be selected according to the requirements of the bending radius of the pipe. Put the drawn pipe into the mold of the pipe bender, align the bending point of the pipe with the bending point of the pipe bender, and then tighten the fixture. When bending the pipe, the bending point should be continuous when the bending point is greater than the required viewpoint l° ~ 2°, and the bending machine should be returned to the bending point. Measure the zigzag radius and zigzag view point with a template.
It should be noted that the outer diameter of the bent pipe must be closely fastened with the bending mold, otherwise the pipe will be dented. Hot simmering method: When using hot simmering method for pipes with large diameters, fill the tube with sand before simmering and plug it tightly at both ends. After heating on the oven or coke fire, place on the mold and twist.
