The invention provides a rolling plate unrolling device, comprising a spindle, an expanding and shrinking tile block arranged outside the spindle, a drive component, an expanding and shrinking sliding block arranged on the spindle and an expanding and shrinking regulating table fixedly arranged inside the expanding and shrinking tile block; the inclining outside surface of the expanding and shrinking sliding block is slidably connected with the inclining inside surface of the expanding and shrinking regulating table; the drive component drives the inclining outside surface and the inclining inside surface to relatively slide to change the radial distance between the expanding and shrinking tile block and the spindle. Since the expanding and shrinking sliding block and the expanding and shrinking regulating table are in surface contact and have higher structural strength, the rolling plate unrolling device can bear larger weight compared to a connecting rod structure, thereby improving the applicability of the rolling plate unrolling device.
Description
technical field [0001] The invention relates to the technical field of plate processing, in particular to a plate rolling and unwinding device. Background technique [0002] Before the sheet metal stamping operation, the coiled sheet needs to be unrolled by the unwinding device and shaped by the shaping device. In order to facilitate the insertion of the unwinding device into the through hole in the middle of the coiling plate and clamping to drive the coiling plate to rotate, the unwinding device is generally provided with an expandable main shaft. Specifically, expansion and contraction pads are arranged on the outside of the main shaft, and the distance between the expansion and contraction pads and the main shaft is adjusted by using the link mechanism, so as to realize the expansion and contraction of the main shaft and change the clamping degree with the coil. However, due to the standard limit value of the coiled plate, the size of the middle through hole for inserti...
