[0051] See also Figures 8 to 11Furthermore, a bracket 425 is fixedly connected to the surface of the bending rod 422, an electromagnet 426 is inlaid on the surface of the bracket 425, a return spring 427 is connected between the limit plate 524 and the bracket 425, and a slag discharge port 14 and a slag drop port 314 are respectively provided on the surfaces of the bearing bottom shell 11 and the rotating shell 31, and the slag drop port 314 is distributed between the slag guiding pipe 423 and the slag discharge port 14.

[0052] In an embodiment of the present invention, angle sensors are installed on the surfaces of the rotating shell 31 and the second rotating rod 512 for real-time monitoring of the rotation angle. When the electromagnet 426 is energized and magnetically fits with the magnetic ring 5241, the third transmission gear 523 is connected to the linear tooth groove 313. When the electromagnet 426 is de-energized, the elastic force of the reset spring 427 drives the magnetic ring 5241 to contact the bottom of the rotating shell 31, and the third transmission gear 523 is disengaged from the linear tooth groove 313.

[0053] Working principle: first, put the blank into the die cavity 511, and use the telescopic cylinder 21 to hammer the blank using the forging block 22. Then, use the driving part 32 and the first transmission gear 33 to control the rotation of the rotating shell 31, the position adjustment mechanism 4 and the lower die assembly 5. The second transmission gear 414 and the annular tooth groove 13 are connected to each other in a synchronous rotation with the rotating shell 31 to drive the transmission sleeve 412 to rotate. The rotating transmission sleeve 412 uses the curved guide rail 413 and the spherical protrusion 424 to slide and connect to drive the bent rod 422 and the rotating sleeve 522 to make reciprocating linear or radial motions along the first linear guide rail 311 and the second linear guide rail 312 respectively. The blank rotates and reciprocates radially under the forging block 22 at the same time, which can ensure that the force distribution of the blank is uniform during the forging process, thereby preventing the surface of the formed product from warping, cracking or deformation.

[0054] When the formed product is taken out, the electromagnet 426 is first energized. Since the electromagnet 426 after being energized is magnetically attached to the magnetic ring 5241, the third transmission gear 523 is connected to the linear tooth groove 313. Then, the driving part 32 and the first transmission gear 33 are used to control the rotating shell 31, the position adjustment mechanism 4 and the lower mold assembly 5 to rotate 360 ​​degrees. The third transmission gear 523 that follows the radially movable shell 42 to make reciprocating radial movements is connected to the linear tooth groove 313 to achieve the purpose of driving the rotating shell 31. The purpose of the reciprocating rotation of the movable sleeve 522 and the worm 521 is that the reciprocating worm 521 drives the lower mold 51 to reciprocate 180 degrees around the second rotating rod 512 through the worm gear 513. After the lower mold 51 rotates 180 degrees, the mold cavity 511 opens downward. Therefore, the particles or impurities generated in the mold cavity 511 during the forging process automatically fall into the slag guiding pipe 423, the slag outlet 314 and the slag discharge outlet 14, which has the function of automatically removing the residue in the mold cavity 511, thereby preventing the residue from damaging the product surface.

[0055] In summary, (1) the present application utilizes a structural design that cooperates with each other among the rotating shell 31, the annular tooth groove 13, the radially movable shell 42 and the transmission sleeve 412, which can automatically control the rotation and reciprocating radial movement of the blank during forging and hammering, thereby ensuring that the force distribution of the blank is uniform during the forging process, thereby preventing the surface of the formed product from warping, cracking or deformation, and has the characteristics of good forging forming effect.

[0056] (2) The present application utilizes the design of mutual cooperation among the lower die assembly 5, the worm 521, the linear tooth groove 313, the electromagnet 426 and the slag guiding pipe 423. During the process of the rotating shell 31 rotating one circle to control the gap between material removal and material feeding, the lower die 51 can be driven to rotate 180 degrees. The particles or impurities generated in the die cavity 511 during the forging process automatically fall into the slag guiding pipe 423 and are discharged outward, which has the characteristics of automatically removing residues and preventing residues from damaging the product surface.
