[0041] Working principle: When metal parts need to be forged, use this equipment, first place the metal blank on the forging table 5, then close the two partition doors 4, and use the stamping component 2 to hammer the metal blank; The screw rod II 20 rotates under the drive of the motor, and then drives the two rectangular frames 7 to move toward each other, and then drives the clamping mechanism, the rotating mechanism, and the moving mechanism to move. When the push rod 14 contacts the metal blank, the metal blank pushes the push rod 14 to move into the slide cylinder 15, and the convex ball provided at the rear end of the push rod 14 slides in the threaded slide groove 1801, and then drives the rotating assembly 18 to rotate, thereby pushing the connecting seat 16 to move through the connecting plate II 17, and then drives the clamping plate 13 to flip, so that the clamping plate 13 clamps the metal blank; Then the screw rod Ⅰ19 rotates under the drive of the motor, and then drives the lifting slider 8 to move, thereby driving the rotating mechanism and the clamping mechanism to move, and the metal blank is separated from the forging table 5. At this time, the rotating block 9 rotates under the drive of the motor, and then drives the connecting arm 10 to rotate, thereby driving the clamping mechanism to rotate, and then drives the metal blank to flip the rotating block 9 to rotate and drive the linkage gear 21 to rotate, and then drive the linkage rack 22 to move, thereby driving the linkage frame 23 to move, and then drive the scraper 24 to move, so that the scraper 24 scrapes off the residue falling on the forging table 5 to avoid the residue affecting the forging accuracy during the next forging; After the metal blank is turned over, the lifting slide block 8 then drives the clamping mechanism to move upward, so that the linkage gear 21 is separated from the linkage rack 22. At this time, the linkage rack 22 is reset under the action of the spring, and then the screw rod II 20 is driven by the motor to rotate in the opposite direction, and then drives the two rectangular frames 7 to move in the opposite direction, thereby driving the clamping mechanism to move in the opposite direction, so that the clamping plate 13 is separated from the metal blank, and the push rod 14 is in contact with the metal blank under the action of the spring. At this time, the two push rods 14 support the metal blank, which is convenient for forging; Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is defined by the appended claims and their equivalents.
