The forming process of the bending pipe
Intermediate frequency pipe bending machine process of pipe bending is stay in steel pipe bending part of the set of induction coil, mechanically pivoted arm stuck pipe head, medium frequency induction coil, bend in zhongtong into the intermediate frequency current heating tube, when the steel tube temperature to the plastic state, after the steel pipe end with mechanical thrust forward, bending, bending make steel tube parts with coolant cooling rapidly, this heating, while advancing, bending, while cooling, constantly to bend pipe bending. |
