Working principle of the pressure device of the crocodile shearing machine

The working principle of the pressure device of the crocodile shearing machine mainly involves the hydraulic pump driving to generate pressure, and the lifting and contraction of the oil cylinder is achieved through the control of the electromagnetic directional valve and oil circuit, using the lever principle to achieve the shearing action. ‌

The working principle of the crocodile shearing machine mainly includes the following steps:

Hydraulic pump drive: Firstly, the hydraulic pump drives the formation of pressure. This is achieved by driving the hydraulic pump through an electric motor, generating the necessary hydraulic pressure to provide power for the shearing action. ‌

Electromagnetic directional valve control: The lifting and contraction of the oil cylinder are achieved through the control of the electromagnetic directional valve and oil circuit. The function of an electromagnetic directional valve is to control the flow direction of hydraulic oil based on electrical signals, thereby controlling the direction and speed of the cylinder's movement. ‌

Leverage principle shearing: Pre press the material under the lifting pressure of the oil cylinder, and then achieve interactive shearing under the lifting action of the oil cylinder. Using the principle of leverage, the upper and lower crocodiles achieve interactive shearing through the thrust and pressure of the oil cylinder, thereby cutting the material entering the incision. ‌

In addition, the operation of the crocodile shearing machine also includes the control of pressing and shearing actions. Through button operation, the direction and flow rate of hydraulic oil can be controlled, thereby controlling the movement of the pressing and shearing cylinders, achieving material compression and shearing
