Uncoiler for cross cut shear

Abstract

The invention discloses an uncoiler for a cross cut shear. The uncoiler comprises a support base, the support base is provided with a rotating seat, and an uncoiler head is fixed to the rotating seatthrough a rotating bearing supporting system; the uncoiler head is provided with an opened clamping jaw system; and a driving disc is arranged on the back of the uncoiler head, a driving device is arranged on the upper part of the rotating seat, the driving device is provided with a driving head, the driving head is matched with the driving disc, and the driving head is mounted on a driving motor.The uncoiler head is driven from a large circular surface through the driving head, on the one hand, speed reduction is achieved, so that driving is smoother, on the other hand, through a speed reduction device, driving torque is reduced, and driving reliability is improved.

Description

technical field [0001] The invention relates to an uncoiler used for cross-cutting, which provides support for strip steel raw materials. Background technique [0002] In the field of silicon steel sheet stamping, the uncoiled strip steel needs to be erected on the uncoiler according to the needs, and the strip steel is slowly output through the uncoiler. A conventional uncoiler has an expanding coil head, and the steel strip is erected on the coil head, and then the head is driven to release the steel strip. [0003] For conventional equipment, the central axis of the uncoiler head is the center of rotation, and the drive motor directly drives the central axis through the pulley, and then drives the uncoiler head to rotate; such a driving method leads to a large driving inertia, and because the steel coil is loaded , the entire machine head will be very heavy, resulting in a very obvious driving discontinuity, and it cannot be stopped in time, resulting in the output strip...

[0003] For conventional equipment, the central axis of the uncoiler head is the center of rotation, and the drive motor directly drives the central axis through the pulley, and then drives the uncoiler head to rotate; such a driving method leads to a large driving inertia, and because the steel coil is loaded , the entire machine head will be very heavy, resulting in a very obvious driving discontinuity, and it cannot be stopped in time, resulting in the output strip being too long and drooping, which will affect the subsequent stamping accuracy
