[0026] Because its main shielding plate 5 and auxiliary shielding plate 6 are located on the left and right sides of the upper mold 8 and the lower mold 9, it will hinder the loading and unloading of materials, resulting in inconvenience in unloading materials. Therefore, the device is provided with a sliding plate 11 that can slide, and the lower mold 9 is arranged on the sliding plate 11. When unloading or unloading materials, the sliding plate 11 can be slid out to take and place the workpiece in the lower mold 9, which is very convenient.

[0032] During the insertion into the clearance groove 7, the roller 53 will first contact the clearance groove 7 to guide the shielding plate;

[0033] In addition, the shielding rubber pad 54 can shield the clearance groove 7, thereby preventing the oxide scale from entering the clearance groove 7 and affecting the insertion of the shielding plate.

[0034] Working principle: connect the upper die frame 1 to the external forging equipment, then place the metal workpiece to be forged in the lower die 9, and then drive the upper die frame 1 to move through the forging equipment, so that the metal workpiece is forged and formed through the upper die 8 and the lower die 9.
