[0046] The first cylinder 4 can drive the lifting plate 5 and the mold 6 to move downward, and the pin feet below the mold 6 are punched and bent, and the pin feet can be placed into the disc vibrating feeder 27. The disc vibrating feeder 27 is started, and the transformer pin feet are automatically sent to the feeding end of the feeding track 12 one by one. The pin feet slide downward along the second chute 13 of the feeding track 12 under the action of gravity, and are arranged inside the second chute 13 by the limiting plate 16. Then the third cylinder 22 is started, and the top plate 23 and the fixed plate 24 are driven to move downward, and then the push plate 25 and the feeding plate 26 are driven to move downward. When the feeding plate 26 moves downward, it will be inserted behind the first pin foot limited by the limiting plate 16, and the push plate 25 will move to one side of the pin feet inside the first chute 10. Then the second cylinder 21 is started, and the sliding seat 20 is driven to move forward. The sliding seat 20 moves forward with the top plate 23 and the fixed plate 24 driven by the third cylinder 22, and then the push plate 25 and the feeding plate 26 move forward synchronously. The feeding plate 26 pushes the first pin foot limited by the limiting plate 16 into the first chute 10, and makes it below the mold 6, completing the feeding work of the pin feet. The resistance plate 15 can generate resistance on both sides of the pin feet to avoid automatic sliding downward under the action of gravity.

After the pin foot passes, the limiting plate 16 moves back under the action of the second spring 18, and continues to intercept the subsequent pin feet. Under the alternating work of the first cylinder 4, the second cylinder 21 and the third cylinder 22, the pin feet arranged in the second chute 13 complete the feeding-punching-bending-discharging work one by one.
