The working principle of the invention is as follows: after the forging top frame 2 finishes one-time hammering, the motor 509 is started and drives the groove rod 510 to rotate along with the upward movement and the reset of the forging top frame 2, and as the pin rod 507 at the bottom side of the bottom frame 501 penetrates through the groove rod 510 and is inserted into the inverted U-shaped rail frame 508, the bottom frame 501 and the double-rod frame 502 respectively form sliding assembly with the first straight guide rail 503 and the second straight guide rail 504 through the unit sliding block 505 and the double-position sliding block 506, so that the bottom frame 501 and the double-rod frame 502 can be driven to reciprocate and linearly move when the motor 509 works, and the bottom frame 501 and the double-rod frame 502 also reciprocate and move up and down, and finally the movement path of each clamping rod 512 is identical to the shape of the inverted U-shaped rail frame 508;
during the initial upward movement of the clamping bar 512, the end of the lifting bar 520 moves from the bottom of the Z-shaped vertical guide groove 518 to the top, and when the end of the lifting bar 520 moves inside the middle inclined transition section 519, the clamping bar 512 moves towards the die holder under the action of the first compressed spring 515, and drives the corresponding steel to move upwards and leave the corresponding die holder under the clamping action of the clamping bars 512 at both sides, then the steel is conveyed above the next die holder when the clamping bar 512 moves horizontally, and finally the steel is released by the clamping bars 512 at both sides when the clamping bar 512 moves downwards, and when the clamping bar 512 releases the steel, the steel falls freely and finally falls into the inside of the next die holder because the length of the vertical part at one end of the inverted U-shaped rail 508 is shorter than the length of the vertical part at the other end;
finally, the motor 509 drives the slot rod 510 to reversely reset so as to perform the next process of clamping movement, wherein the tail end of the clamping rod 512 slides on the surface of the lifting rod 520 when the clamping rod 512 moves horizontally, and drives the lifting rod 520 to move up and down when the clamping rod 512 moves up and down, the lifting rod 520 only moves up and down but does not move axially, the transverse slot plate 521 correspondingly slides in the outer wall of the lifting guide 517 when the lifting rod 520 moves horizontally, but when the lifting rod 520 moves horizontally, namely, the end of the lifting rod 520 moves in the middle inclined transition section 519, the end of the lifting rod 520 moves relatively with the transverse slot plate 521, and in addition, the width dimension of the middle inclined transition section 519 is larger than the diameter dimension of the lifting rod 520, so that even though the clamping rod 512 contacts with the edge of a die holder, the process of clamping steel by the subsequent clamping rod 512 can not be influenced.
