The second crank shaft 601 is rotatably connected to the linkage arm 602, and the ends of the linkage arm 602 are rotatably connected to the push-pull rod 603. The push-pull rod 603 passes through the lower stamping die 409 and then rotates with the lower stamping die 409. The stripping plate 604 is fixedly connected, and the stripping plate 604 is embedded in the bottom surface of the cavity of the lower stamping die 409. One end of the second crank shaft 601 is fixedly connected to the first fixing rod 608, and the first fixing rod 608 passes through the rotating block 401 and the rotating shaft 402 in sequence and is fixedly connected to the first connecting frame 605. The two ends of the first connecting frame 605 are respectively fixedly connected to the mounting frame 2. The other end of the second crank shaft 601 is fixedly connected to the second fixing rod 609, and the second fixing rod 609 passes through the rotating block 401, the rotating shaft 402 in sequence. The rotating shaft 402 and the ratchet assembly 206 are fixedly connected to the second connecting frame 606, and the two ends of the second connecting frame 606 are respectively fixedly connected to the slide rail 204. In this embodiment, when the rotating block 401 rotates, the second crank shaft 601 and the mounting frame 2 are relatively stationary. Taking the lower stamping die 409 at the upper end as an example, in the initial position, the linkage arm 602 is located on one side of the groove of the second driving shaft. At this time, the stripping plate 604 is just embedded in the bottom surface of the cavity of the lower stamping die 409, so that the bottom surface of the cavity is a flat surface. , so as to facilitate stamping and forming. The wheel after stamping and forming is located in the lower stamping die 409. Then, with the rotation of the rotating block 401, the linkage arm 602 rotates from one side of the groove of the second crank shaft 601 to the other side. At this time, the linkage arm 602 changes from one side of the groove to the convex side, so that the linkage arm 602 pushes the push-pull rod 603 to move outward, and the push-pull rod 603 pushes the stripping plate 604 to move outward, so that the wheel formed in the lower stamping die 409 is pushed out through the stripping plate 604, thereby realizing the stripping operation.

[0033] See also Figure 1In one embodiment of the present invention, a material guide groove 6 is opened in the middle of the upper end of the mounting table 1, and the material guide groove 6 is located below the lower stamping die 409. The runner after stripping falls into the material guide groove 6, and then the stamped runner is guided out of the device along the material guide groove 6.

[0034] See also Figure 1-Figure 8 The working principle of the present invention is as follows: when in use, first place the material plate on the lower stamping die 409 at the upper end, then step on the operating pedal, and drive the first crankshaft 105 to rotate one circle through the cooperation of the clutch 107 and the brake 110. During this process, the first crankshaft 105 drives the sliding block 102 and the upper stamping die 104 below to stamp downward through the connecting rod structure 101, and then returns to the initial position upward, and the stamping forming is completed through the cooperation between the upper stamping die 104 and the lower stamping die 409. In the process of the upper stamping die 104 returning to the initial position, under the power transmission of the linkage component 5, the rotating block 401 starts to rotate, so that the lower stamping die 409 at the upper end is flipped downward, and in the flipping process, the forming wheel in the lower stamping die 409 is pushed out by the stripping component, thereby completing the stripping, and the lower stamping die 409 at the lower end is flipped to the upper end, so that the stamping operation can be performed again, and the above operation can be repeated to perform continuous stamping.
