High Frequency Heat Induction Bending Machine.


      Hines Model 630 Induction makes a bend while a tube 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 and 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 tube with a whirling current and in turn the temperature rises, forming a red ring. When it's up to 800-1000°, the tube possesses the nature of plastic status. At the same time, a bending torque exerts to make a bend. At the same time, the pipe is also being pushes hydraulically, maintaining a very smooth bend during the process.




In order to cool down the ring and fix the bent part of the tube, there are many small holes are available on 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 process


When the bend is larger than 90 degrees, the radius will be increased and can result in slight out of roundness of the bend curve. A slow speed can help improve this. Or a center pull rod can help positioning.

Front Clamping Locking Cylinder, Mounted on the bend arm slot, the front clamp holder can clamp on the front end of the tube firmly. The adjuster (screw rod) on the bend arm is available to set up the radius, the distance between the tube and the bend arm rotating center or the pivot. The clamp (hinge) opens and closes hydraulically. Once the tube is put in the clamp die, close the clamp and the twin cylinders drive a pair of screw rods to push on and lock the clamp and hold down the tube firmly.




The clamp holder is secured on the bend arm, and the bend arm sits on the pivot. To adjust for various radii, you need to adjust the clamp and pivot in relation to the bending center so that the distance the pivot is away from the bending center equals the radius. Note, the clamping center in the front clamp must coincide with the bend center. Oil motors are available to drive, via the gearboxes, the screw rod and in turn it moves the pivot. The clamping center is adjusted in the same way.



In bending, the bend arm is driven by the main cylinders to rotate clockwise. To minimize the resistance from the bend arm, a pair of rollers are mounted under the arm driven by oil motors. Under a low pressure, it can self rotate. When a bend is over, it homes itself by the oil motor driving the rollers under the bend arm. It's mounted with an encoder sensing the degree of bend to the control system. The rollers help support the long bend arm.
