Automatic cutting device for tree-shaped castings

The invention discloses a tree-shaped casting automatic cutting device which comprises a machine box, supporting legs are arranged at the four corners of the bottom of the machine box, a control panel is arranged on the machine box, and a frame is arranged in the machine box. The frame is provided with a clamping mechanism and a cutting mechanism which is located on the lower portion of the clamping mechanism and used for cutting the two sides of the tree-shaped casting at the same time. The lifting driving mechanism is connected with the clamping mechanism and used for driving the clamping mechanism to integrally lift; the width adjusting mechanism is connected with the cutting mechanism and used for driving the cutting mechanism to adjust the width so that the cutting mechanism can cut the two sides of the tree-shaped castings with different widths; the output end of the control panel is connected with the controlled ends of the clamping mechanism, the cutting mechanism, the lifting driving mechanism and th
