[0021] By placing module 5 between the upper large wheel mold 6 and the stabilizing plate 7, when the cylinder 2 is started, the lifting plate 3 inside the forging machine body 1 can be raised and lowered. Thus, the lifting plate 3 can drive the gravity block 4 to be raised and lowered repeatedly to hammer the top of the upper large wheel mold 6. Therefore, module 5 between the upper large wheel mold 6 and the stabilizing plate 7 is forged.

[0022] Example 2, see attached document Figures 1 to 5 Based on Embodiment 1, in order to maximize the adjustment angle of the distribution box body at the top of the installation frame adjustment angle 1, the top surface of the stabilizing plate 7 is fixed with a lower large wheel mold 11 by screws. The top surface of the lower large wheel mold 11 is fixed to the bottom surface of the lower extrusion protrusion ring 12. A module 5 is provided on the top of the lower extrusion protrusion ring 12. An upper extrusion protrusion ring 13 is provided on the top surface of the module 5. The top surface of the upper extrusion protrusion ring 13 is fixed to the bottom surface of the upper large wheel mold 6. A core roller 8 is integrally provided on the top surface of the stabilizing plate 7. A guide groove 9 is opened on the outer surface of the core roller 8. A guide block 10 is movably provided on the surface of the guide groove 9. The outer surface of the guide block 10 is integrally provided inside the upper large wheel mold 6.

[0023] By fixing the extrusion ring 13 to the bottom surface of the upper large wheel mold 6, and then fixing the bottom surface of the lower extrusion ring 12 to the top surface of the lower large wheel mold 11, the stabilizing plate 7 is placed on the top surface of the base of the forging machine body 1.

[0024] In actual use, by placing module 5 between the upper large wheel mold 6 and the stabilizing plate 7, when the cylinder 2 is started, the lifting plate 3 inside the forging machine body 1 can move up and down. Thus, the lifting plate 3 can drive the gravity block 4 to move up and down repeatedly to hammer the top of the upper large wheel mold 6. Therefore, module 5 between the upper large wheel mold 6 and the stabilizing plate 7 is forged. By fixing the extrusion ring 13 to the bottom surface of the upper large wheel mold 6, and then fixing the bottom surface of the lower extrusion ring 12 to the top surface of the lower large wheel mold 11, the stabilizing plate 7 is placed on the top surface of the base of the forging machine body 1. When the gravity block 4 hammers the top of the upper large wheel mold 6, module 5 can be forged. By setting the guide block 10 in the integrally formed upper large wheel mold 6, and the surface of the guide block 10 is movable in the guide groove 9, the upper large wheel mold 6 is stabilized on the top of the stabilizing plate 7 to achieve a positioning effect.
