What is the principle of a hydraulic press? The working principle of the hydraulic press

A complete hydraulic system consists of five parts, namely power components, actuators, control components, auxiliary components, and hydraulic oil.

The function of the power element is to convert the mechanical energy of the prime mover into the pressure energy of the liquid, which refers to the oil pump in the hydraulic system, which provides power to the entire hydraulic system. The structural forms of hydraulic pumps generally include gear pumps, vane pumps and piston pumps.

The role of actuators, such as hydraulic cylinders and hydraulic motors, is to convert the pressure energy of the liquid into mechanical energy to drive the load in a linear reciprocating or rotary motion.

Control elements (i.e., various hydraulic valves) control and regulate the pressure, flow and direction of fluids in hydraulic systems. According to the different control functions, hydraulic valves can be divided into pressure control valves, flow control valves and directional control valves. Pressure control valves are divided into benefit flow valves (safety valves), pressure reducing valves, sequential valves, pressure relays, etc.; Flow control valves include throttle valves, adjusting valves, diverter collector valves, etc.; Directional control valves include check valves, hydraulic check valves, shuttle valves, reversing valves, etc.

According to different control methods, hydraulic valves can be divided into on-off control valves, fixed-value control valves and proportional control valves.

Auxiliary components include oil tank, oil filter, oil pipe and pipe joint, sealing ring, pressure gauge, oil level oil temperature gauge, etc.

Hydraulic oil is the working medium for transferring energy in the hydraulic system, and there are several categories such as various mineral oils, emulsions and synthetic hydraulic oils.

To put it simply, the oil acts on the device, and the device acts on the workpiece.

The oil pump pumps out the hydraulic oil and enters the oil cylinder to generate pressure through the oil circuit switch controlled by the solenoid valve.

1. The rotation of the hydraulic press is a transmission mode that uses the hydraulic pressure to transmit power and control, and the hydraulic device is composed of a hydraulic pump, a hydraulic cylinder, a hydraulic control valve and hydraulic auxiliary components;

2. Hydraulic pump: a conversion device that converts mechanical energy into hydraulic energy;

3. Hydraulic cylinders are also known as actuators such as hydraulic motors: convert hydraulic energy into mechanical energy;

4. Control valve: control the flow, flow direction, pressure, working sequence of the hydraulic actuator and protect the hydraulic circuit.

The hydraulic press is composed of two parts: the main engine and the control mechanism. The main engine part of the hydraulic press includes the fuselage, the main cylinder, the ejector cylinder and the liquid-filled positive opening. The power mechanism is composed of a fuel tank, a high-pressure pump, a low-pressure control system, an electric motor and various pressure valves and directional valves.

It is the principle of the hydraulic system.

1. Detailed answers:

The hydraulic pump is the power source of the hydraulic system, and the hydraulic oil enters the cylinder piston through the hydraulic pipeline by the force of the pump. Then there are several sets of seals that cooperate with each other in the cylinder piston, and the seals in different positions are different, but they all play the role of sealing, so that the hydraulic oil can not leak. Finally, through the one-way valve, the hydraulic oil is circulated in the oil tank, so that the cylinder piston circulates to do work.

2. The hydraulic press is composed of two parts: the control section and the main engine.

The power mechanism is composed of a fuel tank, a high-pressure pump, a low-pressure control system, an electric motor, a high-pressure valve and a directional valve. Under the control of electrical devices, the power mechanism realizes the conversion, regulation and transmission of energy through pumps, cylinders and various land hydraulic valves, and completes the cycle of various public welfare actions.

The main engine part includes the fuselage, the master cylinder, the ejector cylinder and the flushing device. Hydraulic press is a series of general-purpose pressing equipment, such as powder product molding, plastic grip product molding, cold (hot) extrusion metal forming, sheet splicing and stamping, bending, flanging, correction and other processes.

The hydraulic press has an independent electrical system of power mechanism, which is centrally controlled by buttons, which can realize three working modes: adjustment, manual and semi-automatic; The working pressure, pressing speed and slider stroke of the hydraulic press can be adjusted according to the needs of the process, and can complete the ejection process, without ejection process, stretching process three kinds, each process is for constant pressure, fixed process two kinds of process action for choice, constant pressure molding process has pressure holding, time delay, automatic return after pressing. In addition to the above functions, the ejection cylinder also has ejection, delay and automatic return. The hydraulic press is suitable for the pressing process of plastic materials.

The working principle of the CNC hydraulic press should be to control the motor through complex electrification control, drive the hydraulic pump to generate pressure, and drive the hydraulic cylinder to press down or on the top to achieve the work.

CNC hydraulic press is a device that uses hydraulic oil to transmit pressure to the pin cover. When the hydraulic oil transmits pressure in the closed accommodating alarm, it follows Pascal's law, and the hydraulic transmission system of the hydraulic press consists of a power mechanism, a control mechanism, an actuator, an auxiliary bucket positive assistance mechanism and a working medium group.

1. The hydraulic press is a kind of hydraulic press, the hydraulic press uses oil to transmit pressure, and there are many kinds of hydraulic presses, which can be used to transmit pressure with oil or water, and most hydraulic presses use oil.

2. Hydraulic press (a kind of hydraulic press) is a kind of special hydraulic oil as the working medium, through the hydraulic pump as the power source, relying on the force of the pump to make the hydraulic oil enter the cylinder piston through the hydraulic pipeline, and then the cylinder piston has several groups of seals that cooperate with each other, the seals in different positions are different, but they all play the role of sealing, so that the hydraulic oil can not leak. The ultimatum is passed through the one-way valve to make the hydraulic oil circulate in the oil tank, so that the cylinder and piston cycle to do work, so as to complete a certain mechanical action as a kind of machinery for productivity.

3. The hydraulic press is a kind of machine made of liquid as the working medium and made according to Pascal's principle to transfer energy to achieve various processes. The hydraulic press is generally composed of three parts: the machine (main engine), the power system and the hydraulic control system. Hydraulic presses are classified into valve rental Wang Fengmen hydraulic presses, liquid hydraulic presses, and engineering hydraulic presses.
