Many people know how the hydraulic shearing machine works, but the working principle of the hydraulic shearing machine blade may not be understood. At this time, we have to talk about the working principle of the hydraulic shearing machine blade.
The hydraulic shearing machine blade is made by the main oil cylinder (fixed on the wall plate) for the downward shearing movement and the nitrogen cylinder returning. The upper tool holder of the pendulum shearing machine is rounded around a fixed axis during the shearing process. The arc swings, through the action of the lever, the motion and the movable knife are transmitted to the shearing blade to complete the entire shearing process.
Therefore, the rigidity of the whole machine has a great influence on the quality and precision of the shearing plate, which is the decisive factor of the service life of the blade. The structural design and assembly quality of the machine tool will cause the deformation of the machine tool itself during the shearing process. The dynamic rigidity of the machine tool includes the shearing. The deviation of the relative position of the machine tool after the force is cut, the repetitiveness of the tool path trajectory is not uniform, the blade shear gap is unstable, the machine tool failure rate is high, the blade life is short, and the work is lost.
