Intermediate frequency pipe bender is used to make intermediate frequency pipe bender with different angles. It is heated on steel pipe by intermediate frequency line trap. The heating belt is heating coil, which is about 40mm, and the heating temperature is controlled at 800-850 degrees Celsius.

The steel pipe is bent under the propulsion of the intermediate frequency pipe bender, and is propelled by the hydraulic cylinder. The front of the intermediate frequency pipe bender is worn with a rocker arm. The role of the rocker arm is to grasp the steel pipe to make a certain turn. In this way, the Angle of the bend is not easy to deform, and the roundness is the same or the effect of no deformation.

The bending radius of intermediate frequency pipe bender is 5 times of the outer diameter of the pipe being bent.

Steel tube better molding R should be in intermediate frequency within the jib fan with pipe bending machine, and a molding, forming after the surface is smooth, but when a steel tube with two or more bending R, to ensure the overall shape, it is quite difficult to meet the drawing requirements: for R in intermediate frequency of pipe bender jib outside the scope of the steel tube, only in straight and curve. Interval bending will lead to obvious concave and convex scars at the heating elbow and the cooling flat, generally about 6mm.

When the total arch height of the bent steel pipe exceeds the feed width of the pipe bender, it is difficult to re-bend if out-of-tolerance is found: if re-bending is necessary, it can only be compensated by intermittent compensation.

In addition, as the steel pipe needs to be heated back and forth, its material properties will be affected at high temperature, especially for the steel pipe of high strength material.

There are three cooling methods for steel pipe after hot bending, namely water cooling, air cooling and natural cooling. At present, air cooling or natural cooling are generally adopted.

Medium frequency pipe bending machine manufacturers mainly produce various types of bending machine, bending machine, three-way machine, press, beveling machine, straightening machine and other molds. Welcome the customers who need to visit our company to order!
