Steel Bending Straightening Machine Stamping Production Line Heavy Material Rack

Steel bending straightening machine, stamping production line, heavy material rack

In the heavy-duty stamping production line, the hydraulic heavy-duty material rack is arranged in parallel with the centering line of the punching machine in front of the leveling machine, the feeder and the punching machine for carrying the coil material and completing the unwinding operation of the coil material, and forming and controlling the material during the unwinding process. After the tension.

The improved heavy-duty material frame rotary joint is connected with the external hydraulic pipeline to use a two-layer steel high-pressure hose with a diameter of 38mm and a length of 1500mm. The connection point is selected in the straight section near the rotary joint, and is fixed so as not to affect the movement of the material frame. The stroke and spindle rotation are subject to change.

The matching clearance between the rotating joint shaft and the bushing is controlled to be 0.04-0.06 mm. The matching precision is high, so that the rotary joint bushing and the material frame swing synchronously.

Change the original 5mm oil drain hole of the rotary joint bushing to two holes of 7mm in the circumferential direction. The pressure of the internal drain fluid is reduced, so that the internal drain fluid can be discharged in time, eliminating the external leakage accident.

The skeleton oil seal adopts a high-quality oil seal which is tightly combined with the skeleton and has good rubber flexibility, which fundamentally solves the problem of frequent oil leakage of the rotary joint, and greatly reduces the material frame failure and the later maintenance cost.
