Composition of hydraulic system for metal shears

As large-scale hydraulic equipment, hydraulic shear is a hybrid product of hydraulic and electromechanical equipment. It is used to drive and control hydraulic components through electrical and mechanical combinations to complete the predetermined operation of the entire hydraulic system. Rezer Machinery explains the system of the hydraulic shear by focusing on the hydraulic shear system Composition and role. A complete metal shear hydraulic system consists of five parts, namely power components, actuators, control components, auxiliary components, and hydraulic oil.

Metal shears

1. The function of the power element is to convert the mechanical energy of the prime mover into the pressure energy of the liquid. It refers to the oil pump in the hydraulic system, which provides power to the entire hydraulic system. The main manifestation of this system is the hydraulic pump in metal shears

2. The role of the actuators (such as hydraulic cylinders and hydraulic motors) is to convert the pressure energy of the liquid into mechanical energy and drive the load for linear reciprocating or rotary motion. The main manifestation of this system in metal shears is the main hydraulic cylinder, press cylinder, packing cylinder, feeding cylinder, etc.


3. The control element (ie various hydraulic valves) controls and regulates the pressure, flow and direction of the liquid in the hydraulic system. According to different control functions, hydraulic valves can be divided into pressure control valves, flow control valves and directional control valves. Pressure control valves are further divided into flow control valves (relief valves), pressure reducing valves, sequence valves, pressure relays, etc .; flow control valves include throttle valves, regulating valves, diverter manifolds, etc .; directional control valves include check valves, Hydraulically controlled check valve, shuttle valve, directional valve, etc. According to different control methods, hydraulic valves can be divided into on-off control valves, fixed value control valves, and proportional control valves. The function of this system is mainly used to control the oil circuit between the hydraulic pump and the hydraulic cylinder and to control the speed and pressure of the cylinder from the aspects of flow and pressure.

4. Auxiliary components include oil tank, oil filter, oil pipe and pipe joint, seal ring, pressure gauge, oil level oil thermometer, etc.

5. Hydraulic oil. Mainly used for transmitting pressure.

Metal shears, also known as gantry-type shears, are suitable for the processing of various scrap steel plates, bars, ferroalloys, special sheets, ship plates at ship recycling plants, automobiles, metal briquettes, iron scraps, and other scrap steel One-time shearing and breaking instead of manual dismantling in order to reduce production costs and achieve efficient and convenient results.
