[0007] Preferably, the electric push rods are symmetrically distributed on both sides of the cutting support frame, positioning grooves are opened at the lower ends of both sides of the cutting support frame, and both ends of the first movable plate extend into the interior of the positioning grooves, the first movable plate is slidably connected to the positioning grooves, and the lower ends of both sides of the first movable plate are connected to the second movable plates.

[0008] By adopting the above technical solution, the first movable plate and the cutting head can be driven to rise and fall by the electric push rod.

[0021] By adopting the above technical solution, the blanking extrusion roller is positioned by the support seat and the positioning shaft. When the support blanking plate rotates and resets, the blanking extrusion roller contacts the metal plate that has fallen down and gradually squeezes it to the right, pushing the spherical shielding part to move in the direction of the positioning bar, thereby moving the metal plate to the right side of the positioning bar for neat stacking.

[0022] Preferably, the positioning frame is slidably connected to the limiting slide rod, and a material discharge groove is opened in the middle of the positioning frame, the limiting slide rod is symmetrically distributed on the front and rear sides of the positioning frame, and a positioning spring is sleeved on the outside of the right end of the limiting slide rod, and the two ends of the positioning spring are respectively connected to the positioning frame and the inner wall of the material discharge box.

[0023] By adopting the above technical solution, the positioning frame can be pushed to move to the left through the design of the limiting slide rod and the positioning spring, and the positioning frame is used to squeeze and limit the metal plate on the right side of the positioning bar to keep it stacked upright, and the blanking groove opened in the middle of the positioning frame can facilitate the subsequent clamping and transfer of the stacked metal plates.
