[0025] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0026] When in use, in the half-shear process, in the mold opening state, the material strip 16 is sent into place, and the inner guide pillar 33 and the outer guide pillar 34 cooperate with the punch press to make the position of the material strip 16 accurate. Under the push of the punch press, the stripper plate 7 and the lower mold plate 8 clamp the material strip 16, and the half-shear punch 17 begins to contact the product. Under the force of the first nitrogen cylinder 20, the half-shear floating block 19 clamps the product. The punch press continues to move downward, and the half-shear punch 17 punches the product into the half-scissor mouth 18. Since the four groups of half-scissor mouth entry blocks 35 are lower than the blade, the product and the material strip 16 are still in a connected state to prevent the product from falling from the material strip 16. When the mold is opened, the half-shear floating block 19 floats out of the product under the force of the first nitrogen cylinder 20; the material strip 16 is sent forward one step to the flanging process At the punch press end, the guide pin is used to accurately position the material strip 16. The stripper plate 7 and the lower mold plate 8 clamp the material strip 16. The flanging punch 24 begins to contact the product. The floating block 26 clamps the product under the action of the second spring 27. Since the product and the material strip 16 were almost cut off before, the connecting material positions at four places will be pulled apart under the traction of the flanging punch 24, so as to separate the product from the material strip 16. After separation, the product continues to move downward, and the product contacts the flanging die 25 for a circle of flanging. In this process, the pressing block 29 clamps the product under the action of the second nitrogen cylinder 30 to accurately position it. After the downward pressing action is completed, it begins to float up, and the floating block 26 floats up and ejects the product under the action of the second spring 27.
