The hydraulic pendulum shearing machine has simple structure, high shearing efficiency, no deformation of the sheet after shearing, and is widely used. The hydraulic shearing machine adopts all-steel welded structure, which eliminates stress by vibration, has stable machine structure, good rigidity, long machine life, and can cut high-quality, burr-free and smooth workpieces. When cutting metal sheets of different thicknesses, it is necessary to adjust different blade gaps to ensure the durability of the blades.
