Lubrication requirements and support effects of automatic hydraulic uncoilers
- Jul 17, 2018 -

The automatic hydraulic uncoiler will be directly at the front end of the inlet part of the unit, and directly corresponds to the steel coil car. The uncoiler of the unit can keep the upper unwinding under the tension of the steel strip, and another significant The function is to achieve automatic centering of the strip under its central control (CPC). The conventional continuous retreat and color coating unit is equipped with two unwinding machines. Since the two unwinding machines are alternately unwinding, it creates preconditions for the continuous production of the subsequent equipment of the unit, and the shearing production line is equipped with an unwinding machine.

The body of the automatic hydraulic uncoiler is in the form of a welded box, and its variable frequency speed regulating motor will drive the reel shaft to provide the main power to the decoiler through its gearbox deceleration. The reel of the uncoiler is a hollow shaft supported by two bearings on the gear housing with a transmission spur gear mounted between the bearings. The gearbox is lubricated by forced lubrication and is equipped with two constant speed motors for the closed loop oil lubrication system. The mandrel is a cantilever structure whose front end is supported by an outer support bearing during unwinding to maintain the rigidity and stability of the uncoiler.

The mandrel of the automatic hydraulic uncoiler effectively connects four sector plates through the inclined dovetail grooves on its four sections, and each of the sector plates is prevented from axially smashing through a radial slide at the trailing end during production. Move, but can achieve radial expansion and contraction. A rotary oil cylinder is connected to the end of the reel shaft, and the cylinder piston rod drives the front end quadrangular axis to axially slide through the rod at the center of the reel shaft, thereby driving the fan plate to radially expand and contract. The roll can be increased in nominal diameter by means of an additional four sector plates.
