Engineering required S bend, T-bends, is through to the steel pipe is heated to form a

The pipe is heated by the intermediate frequency hydraulic propulsion, from Big Bend 60-1220mm models, S curve, T-bends can be processed from. Is based on the model you need and do mechanical equipment. Bending mainly formed by bending frequency heating. In the bending machine machining, often adopted a rolling process to improve the surface hardness, fatigue strength and wear resistance, lower surface roughness, extend the life of the workpiece. Also, you can take advantage of in the process of rolling, the metal plastic deformation under external force, internal stress change to straighten relatively rigid shaft and lever type workpieces. When feeding the last bend, the car may collide with the stamper available at this time "interference zones" function, which die return the car to continue feeding → → bender arm returns → space angle (POB) → Clamping clip tight → chuck release, the car quit interference area → die pressing → bending pipes. Thus, bending only to avoid collision of the car with the die to ensure the successful completion of the final corner, and can reduce the material loss head clamp, lower production costs. Complete linear feed motion (DBB) car, the tube bending process, the tube pulled forward. In this way, dropping the "forward thrust", thus removing the synchronization speed of the car and bent, removed the DC negative feedback system to increase the "positive force" and set simplifies electrical wiring. Because advantageously bent forward thrust of the tube, particularly in the larger diameter of the tube bending, forward thrust is necessary. Therefore, VB bender increased boost means rolling straightening method is for the first time after the workpiece rolling, radial runout workpiece inspection, four marked and, with a four-jaw chuck the workpiece recess adjust to the height of the rotation center of the machine, the size is proportional to the bending of the workpiece, and then a second roll, and then adjusted with a dial indicator and four-jaw chuck jaws, workpiece correction. Dial indicator to check the situation and then bent, as also curved, then the above method, adjustment of the workpiece, a third rolling, until the required straightness of the workpiece up.
