The boost and push rate rates are clamped to the actual environment and held to determine the chamber and the rate of the hydraulic Pipe Cutting Machine. At the same time, it should be checked whether the advance amount of the mandrel placement is appropriate, and the necessary mediation should not be held at that time. Based on the environment of the outer arc of the tube arc, the reason should be elaborated. The pipe should be in a state of excellent heat disposal punishment. The weld of the seamed steel pipe should not be in the bias of F1 and F2, ie Do not face the clamping die and the bending wheel die; check the factors of the pipe and then check if the pressure of the pressing die is too large and mediate the pressure properly.
To deal with the newly used mandrel, check whether the diameter is too large. If the diameter is too large, it is necessary to carry out the necessary grinding, and the core rod and the inner wall of the pipe are well lubricated to eliminate the resistance of the elbow and the friction between the inner wall of the pipe and the mandrel. At the same time, accept the proper pace and stop the machine from shaking. To deal with the inner wrinkles of the arc, the corresponding step should be accepted according to the wrinkle position. If the front cut point is wrinkled, the position of the mandrel should be adjusted forward so that the mandrel is advanced in advance to support the pipe when the bend is reached; After the cutting point is wrinkled, the anti-wrinkle block should be installed, and the anti-wrinkle block should be placed in an accurate position. It can be well attached to the hydraulic pipe cutting machine model, and the pressure of the pressing die (wheel) should be adjusted to make the pressure proper.
