Pinch roll device for introducing strip steel into slitting shear

The utility model discloses a pinch roll device for introducing strip steel into a slitting shear. The device is arranged between an outlet side guide of a temper mill and the slitting shear, and comprises a base, a rotation shaft, swinging arms, pressing rolls, a guide plate and supporting rolls, wherein the rotation shaft is arranged on the base; the swinging arms are fixed on two sides of the rotation shaft; the pressing rolls are arranged on the end parts of the swinging arms by pressing roll bearing seats; the guide plate is welded on the swinging arms; the supporting rolls are arranged on the base by supporting roll bearing seats; a gap, through which the strip steel can pass, can be formed by each pressing roll and the corresponding supporting roll under a condition that the swinging arms are pressed downwards, so that the strip steel can be smoothly introduced into the slitting shear. By virtue of the guide plate on the swinging arms, the head raising of the strip steel is avoided, the strip steel can be effectively guided to smoothly enter the slitting shear, the production efficiency is improved further, and the hidden dangers of personal injury are reduced; when the strip steel is silt, the pressing rolls swing to be pressed downward under the driving of the swinging arms, the strip steel in the gaps between the pressing rolls and the supporting rolls can be smoothly guided into the slitting shear for slitting, the smoothness and the non-deflection of the strip steel and the parallel and level performance of cutting openings of the strip steel can be ensured in the shearing, the shearing quality of the strip steel is improved, and the product yield is improved.
