Referring to fig. 4 and 5, the scrap shearing machine includes a stationary blade 200 and a movable blade 100; the stationary blade 200 and the movable blade 100 move relatively to cut the material. When the scrap steel shearing machine operates, the cutting edge surface of the fixed knife 200 and the cutting edge surface of the movable knife 100 are in opposite positions. The moving blade 100 continuously reciprocates and cooperates with the stationary blade 200 to shear the material. The movable blade 100 and the fixed blade 200 each have a concave-convex bent cutting edge surface, and thus a concave-convex cutting structure is formed on one side of the cutting edge surface. The concave-convex shearing structure of the fixed knife 200 and the concave-convex shearing structure of the movable knife 100 are staggered and opposite to each other, so that concave-convex bent shearing lines are formed.

When the shearing machine works, the movable knife 100 and the fixed knife 200 can be combined step by step along the transverse direction to shear materials step by step. Therefore, the shearing force required at the same moment can be greatly reduced, the shearing smoothness is ensured on the premise of properly prolonging the shearing stroke, the yield is improved, and the influence on the equipment cost is small.

Here, the shear blades before and after the inversion substantially coincide.

In some embodiments, the shear blade 150 has a vertical shear blade 151, and the stationary blade and the movable blade of the shear can be turned over simultaneously to achieve face changing.
