[0051] Working principle: At the beginning of work, the staff turns on the hydraulic telescopic rod 208 and the rotating motor 306. When the staff turns on the hydraulic telescopic rod 208, the hydraulic telescopic rod 208 extends, and the extension of the hydraulic telescopic rod 208 drives the upper mold 209 to move downward until the upper mold 209 contacts the workpiece on the lower mold 206. The upper mold 209 drives the workpiece to move downward, and the workpiece drives the lower mold 206 to move downward. The lower mold 206 drives the first movable plate 205 to move downward until the first movable plate 205 moves to the bottom. After that, the telescopic rod shortens and drives the upper mold 209 to move upward. Under the action of the first spring 204, the first movable plate 205 moves upward. The upward movement of the first movable plate 205 drives the lower mold 206 to move upward, and the upward movement of the lower mold 206 drives the workpiece to move upward until the upper mold 209 is separated from the workpiece, thereby completing the forging of one surface of the workpiece.

[0052] When the first movable plate 205 moves downward, the first movable plate 205 drives the movable box 301 to move downward, the movable box 301 moves downward and drives the first rack 310 to move downward, the first rack 310 moves downward and drives the first gear 309 to rotate, the rotation of the first gear 309 drives the threaded sleeve 308 to rotate, the rotation of the threaded sleeve 308 drives the first threaded rod 305 to move away from the workpiece, the first threaded rod 305 moves away from the workpiece and drives the clamping block 307 to move away from the workpiece, thereby releasing the workpiece. When the first movable plate 205 moves upward, the first movable plate 205 drives the movable box 301 to move upward, the movable box 301 moves upward and drives the first rack 310 to move upward, the first rack 310 moves upward and drives the first gear 309 to rotate, the first gear 309 rotates and drives the threaded sleeve 308 to rotate, the threaded sleeve 308 rotates and drives the first threaded rod 305 to move in a direction close to the workpiece, the first threaded rod 305 moves in a direction close to the workpiece and drives the clamping block 307 to move in a direction close to the workpiece, thereby tightening the workpiece, so that the workpiece can be fixed and positioned, after the clamping block 307 fixes the workpiece, the rotating motor 306 rotates slowly, driving the workpiece to rotate a certain angle, thereby performing multi-faceted forging on the workpiece.

[0053] When the threaded rod rotates, the threaded rod drives the sliding sleeve 401 to rotate, the sliding sleeve 401 drives the clutch 402 to rotate, the clutch 402 drives the first curved rod 403 to rotate, the first curved rod 403 drives the second curved rod 404 to rotate, the second curved rod 404 drives the sliding block 407 to move toward the lower mold 206 until the baffle 411 contacts the lower mold 206, then the third telescopic rod 412 extends, the extension of the third telescopic rod 412 drives the baffle 411 to rotate, the baffle 411 pushes the processed workpiece into the collection box 414, and the unprocessed workpiece rolls from the L-shaped feed pipe 410 to the lower mold 206, thereby realizing automatic loading and unloading.
