Hydraulic Oil Press (hydraulic machine) is a kind of hydraulic oil as a working medium, through the hydraulic pump as a power source, by the pump force to make hydraulic oil through the hydraulic pipe into the cylinder / piston, and then the cylinder / piston Group of the seal with each other, different locations are different seals, but all play a sealing effect, so that hydraulic oil can not be leaked. Finally, through the one-way valve to make the hydraulic oil in the tank cycle to the cylinder / piston cycle work to complete a certain mechanical action as a force of a mechanical.
1 structure
The Hydraulic Oil Press consists of two main parts of the main engine and control mechanism. The hydraulic machine main part includes the fuselage, the master cylinder, the ejection cylinder and the filling device. Power mechanism by the fuel tank, high pressure pump, low pressure control system, motor and various pressure valves and directional valves and other components. Power mechanism under the control of electrical equipment, through the pump and cylinder and a variety of hydraulic valve to achieve energy conversion, regulation and transportation, to complete a variety of process operations cycle.
2 classification
Hydraulic Oil Presses are sorted by structure
Mainly divided into four-column Hydraulic Oil Press (three-beam four-column, five-beam four-column), double-column Hydraulic Oil Press, single-column hydraulic machine (C-shaped structure), frame Hydraulic Oil Press.
According to the use of Hydraulic Oil Press classification
Mainly divided into metal forming Hydraulic Oil Press, bending Hydraulic Oil Press, drawing Hydraulic Oil Press, punching Hydraulic Oil Press, powder (metal, non-metallic) forming Hydraulic Oil Press, pressure Hydraulic Oil Press, extrusion press, extrusion molding.
3 Features
Hydraulic pump direct drive hydraulic machine has the following characteristics
1, hydraulic machine activities The speed of the beam depends on the pump supply volume, and the process of forging deformation resistance has nothing to do. If the pump supply is constant, the working speed of the Hydraulic Oil Press is fixed.
2, the pump supply pressure and the power consumed by the workpiece deformation resistance of the workpiece, the work of deformation resistance, the pump supply pressure and the power consumption is also large, otherwise small.
3, can use the activities of the beam speed constant and pump pressure changes in the characteristics of the flow as a signal to manipulate the distributor to achieve automatic control of the Hydraulic Oil Press.
4, the basic investment province, small footprint, daily maintenance and maintenance simple. The hydraulic pump in the pump direct drive system is selected according to the maximum working speed and working pressure of the Hydraulic Oil Press, and the hydraulic pump is not fully utilized when the Hydraulic Oil Press is in the filling process, the return process, the auxiliary process and the required working pressure are small. Is a large tonnage of the hydraulic machine, the utilization factor is very low. Therefore, the Hydraulic Oil Press tends to classify the working speed and working pressure
4 use
Widely used in the automotive industry, spare parts processing and various products of various industries stereotypes, brushes, correction and footwear, handbags, rubber, mold, shaft, bushings parts of the press fit, embossing, sheet metal parts Bending, embossing, sleeve drawing and other processes, washing machines, motors, motor vehicles, air conditioning motors, micro-motors, servo motors, wheel manufacturing, shock absorbers, motorcycles and machinery industries.
