Then, the motor 314 is started, and the rotation of the motor drives the turntable 315 to rotate, and the crawler track 316 moves accordingly, pushing the iron plates out of the iron plate placing bin body 41 in turn. The movement of the crawler track is transmitted to the turntable connecting vertical rod 318 through the second turntable 317, thereby driving the turntable 322 to rotate. The rotation of the turntable 322 causes the control turntable 321 to rotate, and the sliding rod 323 slides in the elliptical slide plate 324 accordingly. The movement of the sliding rod 323 drives the swing rod 325 to swing, thereby pushing the push-pull rod 326 to slide along the inner wall of the concave slide block 3111, and the movement of the push-pull rod 326 causes the push-pull plate 327 to move back and forth, and the iron plate pushing plate 328 pushes the iron plate out of the iron plate placing bin body 41 accordingly; As the iron plate is pushed out, since the topmost iron plate placed on the top of the iron plate placing plate body 451 is not limited by the two inverted L-shaped limit blocks 42, at this time, the reset mechanism 455 starts to work, and the reset rotation rod slider 4554 slides in the bottom plate slide groove 4553 of the reset mechanism bottom plate 4551, and is acted upon by the elastic force of the reset spring 4555, pushing the telescopic rod push-pull rotation rod 4556 to rotate, and the telescopic rod push-pull rotation rod 4556 drives the telescopic rod 4552 to move upward, and finally pushes the iron plate placing plate reset plate 454 upward; The rise of the iron plate placing plate reset plate 454 drives the iron plate placing plate body 451 to rise, and the iron plate placing plate slider 452 continues to slide along the inner wall of the placing bin slide groove 43 until the inverted L-shaped limit block 42 limits the new top iron plate again, preparing for the next round of iron plate pushing operation.

[0024] Working principle of the present invention: when it is necessary to perform stamping forming on the cast iron part, the iron plate of the cast iron part is placed on the top of the two movable plates 295, and then the hydraulic push rod 23 is started, and the hydraulic push rod 23 pushes the pressing plate 24 downward, so that the pressing plate 24 drives the mold connecting plate 26 and the vertical plate 27 to move downward, and the cylindrical mold 28 on the vertical plate 27 contacts the iron plate, and the iron plate is stamped and formed by the cylindrical mold 28. When the iron plate of the cast iron part is stamped and bent into a cylindrical shape, the bidirectional hydraulic push rod 298 is started, so that the arc-shaped rotating rod 297 drives the movable plate 295 to move inward, and the extrusion plate 296 is squeezed inward accordingly, so as to further ensure the cylindrical forming effect of the iron plate of the cast iron part. After completing the stamping forming, it is only necessary for the bidirectional hydraulic push rod 298 to reset the two arc-shaped rotating rods 297 and the hydraulic push rod 23 to reset the pressing plate 24; When a large number of cast iron plates need to be stamped and formed, first, multiple cast iron plates are placed on the top of the iron plate placing plate body 451 on the inner wall of the iron plate placing bin body 41. The top iron plate is limited by two inverted L-shaped limit blocks 42. Then, the motor 314 is started. The rotation of the motor drives the turntable 315 to rotate, and the crawler track 316 moves accordingly, pushing the iron plates out of the iron plate placing bin body 41 one by one. The movement of the crawler track is transmitted to the turntable connecting vertical rod 318 through the second turntable 317, thereby driving the turntable 322 to rotate. The rotation of the turntable 322 causes the control turntable 321 to rotate, and the sliding rod 323 slides in the elliptical slide plate 324 accordingly. The movement of the sliding rod 323 drives the swing rod 325 to swing, thereby pushing the push-pull rod 326 to slide along the inner wall of the concave slide block 3111. The movement of the push-pull rod 326 causes the push-pull plate 327 to move back and forth, and the iron plate pushing plate 328 moves accordingly. The iron plate is pushed out from the iron plate placing bin body 41. As the iron plate is pushed out, since the top iron plate placed on the top of the iron plate placing plate body 451 is not limited by the two inverted L-shaped limit blocks 42, at this time, the reset mechanism 455 begins to play a role, and the reset rotation rod slider 4554 slides in the bottom plate slide groove 4553 of the reset mechanism bottom plate 4551, and is acted upon by the elastic force of the reset spring 4555, pushing the telescopic rod push-pull rotation rod 4556 to rotate, and the telescopic rod push-pull rotation rod 4556 drives the telescopic rod 4552 to move upward, and finally pushes the iron plate placing plate reset plate 454 upward, and the rise of the iron plate placing plate reset plate 454 drives the iron plate placing plate body 451 to rise, and the iron plate placing plate slider 452 continues to slide along the inner wall of the placing bin slide groove 43 until the inverted L-shaped limit block 42 limits the new top iron plate again, preparing for the next round of iron plate pushing operation.
