Pendulum Rotary Shear Cut To Length Line is a common machine, it is driven by the motor swing arm to swing up and down, so as to achieve the cutting of metal sheet. Its working principle is relatively simple, mainly through the swing of the swing arm and the pressure device to achieve the purpose of shearing. The brake shearing machine uses a different working principle, it drives two relative moving blades through the motor, one blade is fixed, the other blade can move, so as to achieve the cutting of the metal sheet. The hydraulic system of pendulum design provides perfect stability for hydraulic pendulum shears, especially during high pressure, strength shear operations. The efficiency of the hydraulic pendulum shears using hydraulic technology is very high in the cutting and processing process, which greatly improves the production efficiency and production quality. Hydraulic pendulum shears have a variety of safety protection mechanisms, through strict control and protection devices to ensure the safety and reliability of the operation.
