[0034] Working principle: When in use, the driving mechanism on the spring machine drives the shear sliding seat 1 to slide back and forth horizontally, so that the shear arm 2 is inserted into the shear position of the spring machine's discharge port. When cutting, the hydraulic cylinder 12 drives and operates to control the punching mechanism 9 to move downward, and relies on the downward punching action of the punching blade 902 to achieve the cutting of spring steel. Because it adopts a downward punching cutting mechanism, compared with the traditional offset cutting structure, it can cut spring steel of any diameter that can be inserted into the shearing groove 6, and it is highly versatile.
