Induction Bending Mechanism
When the electric power is supplied from the high frequency generator to a heating coil surrounding the pipe, a narrow circumferential band around the pipe is heated inductively.
As the appropriate bending temperature is reached, the pipe is mechanically driven through the heating coil and immediately cooled by water or air depending on the kind of materials, while the pipe bending is taking place moving through the heated zone.
The pipe end is clamped at a predetermined distance from the arm post center, which is equal to the radius of curvature, the bending takes place at the tangent point encircled by the heat ring, thus the pipe is bent continuously at a predetermined point with the specified bending radius and angle settings.

High Frequency Heat Induction Bending Machine.
Hines Model 630 Induction makes a bend while a pipe is heated under an induction heating device. Its advantages over a regular cold bender is that it is capable of bending thin-wall tubes and making quality bends without the need of a complete set of dies. As a result, it’s 1/3 to 1/2 of the size of a cold bender both in floor space and price. It is applicable in shipbuilding, chemical, metallurgical, boiler, heavy machine-building industries and especially suitable for small lot productions.
The induction current flowing through the electric heating ring actuates the area of the pipe with a whirling current and in turn the temperature rises, forming a red ring of heat at the required bending site. When it’s up to 800-1000°, the pipe steel possess the nature of plastic status. At the same time, bending torque exerts to make a bend and the pipe is also being pushed hydraulically, maintaining a very smooth bend during the process.
In order to cool down the ring and fix the bent part of the pipe, there are many small holes in the peripheral of the heating ring for the cooling water to flow and spray onto the bent surfaces after flowing inside cavity of the ring. It is a continuous process until the end of the bending.
