Sheet metal decoiler features
The sheet metal decoiler is a special equipment for leveling the metal sheet. The body is a welded box-shaped structure. The frequency conversion speed-regulating motor drives the spool shaft to provide the main power for the uncoiler after deceleration through the gear box.
The sheet metal decoiling machine is arranged at the front end of the inlet section of the unit and will correspond to the No1 and No2 steel drums, respectively. One of the functions of the decoiler of the unit is to uncoil under the tension after the strip is held. Another significant function is that under the central control (CPC), automatic centering of the strip can be achieved. Conventional rewinding and color coating units are equipped with 2 uncoilers, because the two uncoilers are alternately uncoiled to create the prerequisites for continuous production of the subsequent equipment of the unit.
The sheet metal decoiler body is a welded box-shaped structure. The frequency-conversion speed-adjusting motor drives the reel shaft to provide the main power for the uncoiler by decelerating the gear box. The reel of this equipment is a hollow shaft, which supports the gear box body through two bearings. The transmission spur gear is installed between the bearings. The gearbox is lubricated with a forced lubrication system and is equipped with two constant speed motors for a closed-loop oil lubrication system. The mandrel is a cantilever structure, and its front end is supported by an outer support bearing when it is unrolled to maintain the rigidity and stability of the device.
The sheet metal decoiling spindle is connected to four fan-shaped plates by means of oblique dovetail grooves on the four end faces. Each fan-shaped plate passes through a radial slide at the trailing end to prevent its axial turbulence, but it can be increased along the radial direction. Shrink.
When the sheet metal decoiler is in use, it is necessary to pay attention to the rotary cylinder connected to the end of the spool shaft. The piston rod of the cylinder drives the front-end four-axis shaft of the spool through the axis of the spool shaft to axially slide, thereby driving the fan-shaped plate diameter. To shrink. The reel will increase the nominal diameter with an additional four sector plates. The frame of the sheet metal uncoiler machine can be moved on the rails of the machine base and driven by hydraulic cylinders to achieve central position control.
