Box structure and unwinding requirements for coil uncoiler
- Jul 28, 2018 -

The disk round unwinding machine is a welded box structure to a certain extent. When the operation is performed, the frequency conversion motor will drive the reel shaft through the gear box to provide the main power for the unwinder. 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 of the circular uncoiler is a cantilever structure. When unwinding, the front end is mainly supported by the outer support bearing, so that the rigidity and stability of the uncoiler can be maintained. The circular unwinding mandrel is connected to four sector plates through inclined dovetail grooves on four end faces, each of which is prevented from axially swaying by a radial slide at the trailing end, but can be expanded and contracted in the radial direction. .

The circular coil unwinding machine is connected with a rotary oil cylinder at the end of the reel shaft, and the cylinder piston rod drives the front end quadrangular axis to axially slide through the rod of 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. The uncoiler frame can be moved on the rails of the base and driven by hydraulic cylinders for central position control. In order to enhance the stability of the reel, a support arm device is designed on the head of the reel. When there is a steel coil on the reel, the support arm is driven by the oil cylinder to support the reel head, and the support arm is normally retracted without affecting. The coil is rolled up.
