Intermediate frequency pipe bender manufacturing steps

Intermediate frequency pipe bender manufacturing steps

The working principle of the IF pipe bender is to use the IF power to heat the steel pipe and push the steel pipe at a uniform speed to make the steel pipe in the heated part walk along the preset track and form a bend with a certain curvature radius and Angle. Firstly, the steel pipe is installed in place, the bending radius is adjusted by the lead screw nut drive on the rocker arm rotating device, and the steel pipe is heated to a certain temperature by an intermediate frequency induction heating ring before bending. When bending, the steel pipe is pushed forward by the car with hydraulic pressure as the power, and deformed and bent at the heating point along the adjusted bending radius. After steel pipe deformation, water cooling, to obtain the required bend pipe fittings.

Medium FREQUENCY BENDING PIPE IS generally suitable for welding the THIN plate BELOW 6 mm. It has the characteristics of beautiful weld forming and small welding deformation.

The protective gas is argon, 99.99% pure. When welding current is 50~50A, argon flow is 8~0L/min, and when current is 50~250A, argon flow is 2~5L/min. Welding arc length, welding ordinary steel, the best is 2~4mm, welding stainless steel, the best is ~3mm, too long protection effect is not good.

In the process of IF pipe bending, an induction coil is set on the part to be bent, and the pipe head is stuck by a mechanical rotary arm, and the IF current is introduced into the induction coil to heat the steel pipe. When the temperature of the steel pipe rises to the plastic state, the mechanical thrust is used to push the bending at the back end of the steel pipe, and the bending part of the steel pipe is cooled rapidly with coolant, so that the bending pipe is heated, pushed, bent and cooled at the same time.

Medium frequency pipe bender is widely used in pipeline system of petroleum, chemical and other engineering fields. The company mainly produces pipe bender, elbow machine, tee machine, pipe expanding machine, beveling machine, press machine, straightening machine, straight seam welded pipe production line and so on.
