The hydraulic shearing machine's bearing body consists of three main components: the main cylinder, hydraulic cylinder, and part of the upper end of a fluid filling device. These components are integral to the overall structure and function of the machine. In addition, the bearing body includes other essential elements such as the fuel tank power department, high-pressure pump, low-pressure control system, electric motor, and various pressure valves and directional control valves. These components work together to ensure the efficient operation of the machine. The electrical equipment plays a crucial role as it is responsible for managing multiple pumps and valves, as well as facilitating energy conversion, regulation, and delivery. It also controls the hydraulic cylinders, allowing for the smooth execution of various technological actions. Overall, the hydraulic shearing machine's bearing body orchestrates a continuous cycle of actions essential for its proper functioning.
Hydraulic shears can be classified based on their use of Pascal's law, which uses mechanical transmissions to exert pressure via a material liquid. This hydraulic pressure can be adjusted depending on the specific need. The two main types of hydraulic shears are hydraulic and hydropneumatic, depending on the type of pressure liquid that passes through the point.
For larger hydraulic presses, the total pressure generated is often used for forging and stamping. This type of press is divided into two categories: forging hydraulic presses and free forging hydraulic presses. Die forging hydraulic presses, shearing machines, and free forging hydraulic presses all offer different capabilities depending on the desired outcome. For example, die forging hydraulic presses and shearing machines are used for precision shaping, while free forging hydraulic presses are ideal for more general forging needs.
Hydraulic shears operate by utilizing the power of liquid to enhance pressure transmission. According to Pascal's law, when pressure is exerted in an enclosed container, the liquid efficiently transfers this force. Consequently, hydraulic shears demonstrate the principles outlined by Pascal's law as they harness the potential of hydraulic fluid for increased efficiency and effectiveness.
The hydraulic shears' hydraulic drive system is comprised of different components, including the power mechanism, control mechanism, executive mechanism, auxiliary mechanism, and working medium. The power mechanism is responsible for transforming the mechanical power into hydraulic power. It is often referred to as the performance pump body dynamic mechanism, and generally utilizes a positively transformed pump. To meet the speed requirements of the actuator, one or multiple pumps are used. These pumps can include low pressure gear pumps, vane pumps for medium pressure, or high pressure plunger pumps. It is essential to select the appropriate pump(s) based on the specific speed needs of the hydraulic shears.
