Pre-pressing clamp for aluminum-based copper-clad plate production

The utility model discloses a pre-pressing clamp for aluminum-based copper-clad plate production, and particularly relates to the field of aluminum-based copper-clad plate production, a bidirectional air cylinder is fixedly connected to the middle position of the bottom side in a base, moving rods are fixedly connected to the output ends of the left side and the right side of the bidirectional air cylinder, and the moving rods are in sliding connection with guide grooves; the opposite sides of the two moving rods are fixedly connected with clamping plates. The bidirectional air cylinder is started through an external power source, the output end of the bidirectional air cylinder drives the two moving rods to move oppositely, so that the clamping plates on the two sides are driven to move oppositely till the two clamping plates make contact with the left side and the right side of the aluminum-based copper-clad plate, meanwhile, when the clamping plates move, the rolling wheels slide along the surfaces of the
