Aluminum substrate shearing machine

The utility model provides an aluminum substrate shearing machine, which relates to the technical field of aluminum substrate processing, and comprises a side transverse column, a push-type switch A is arranged on the left side of the side transverse column, a push-type switch B is arranged on the right side of the side transverse column, the push-type switch A and the push-type switch B are fixedly connected to the bottom end of a shearing bin, and a raw material conveying belt is controlled to operate after a control part delays for 0.5 seconds. When the shearing knife descends to the lowest point to cut off the aluminum substrate and then moves back upwards, the raw material conveying belt operates to control the raw material aluminum substrate to move forwards, and the large raw material plate forwards pushes the cut part to move into the discharging conveying belt below the front side to be conveyed out in time; and when the telescopic part of the double-acting reciprocating hydraulic cylinder moves righ
