300 tons frame oil press

Name: 300 tons frame oil press

Brand: Jianlong hydraulic Machinery

Basic information

300 tons frame hydraulic press, hydraulic press appearance is "frame type". It is a kind of machinery that makes the hydraulic oil circulate in the tank through the check valve to complete the work of the cylinder and piston to complete a certain mechanical action as a productive force.

use

300 tons frame hydraulic press is suitable for: hardware, gold jewelry, glasses, grinding wheel, electrical appliances, embossing, film, metal plate, watch band (shell, bottom) plastic rubber and other industry products molding. In addition, according to customer requirements, we can produce a series of hydraulic press with pressure holding type and material return device, which is suitable for automatic demoulding of grinding wheel, watch case, metal label, plastic rubber and other industries for heating, shaping and processing products, and can also produce automatic vulcanizing machine with a primary to secondary vent device.

Structural composition

The main structure of the frame hydraulic press is composed of: the main part includes the fuselage, the master cylinder, the ejector cylinder and the liquid filling device. The power mechanism is composed of oil tank, high pressure pump, low pressure control system, motor and various pressure valves and direction valves. The power mechanism under the control of the electrical device, through the pump and cylinder and various hydraulic valves, control valves, control hydraulic oil flow, flow direction, pressure, the working order of the hydraulic actuator and protect the hydraulic circuit.

property

(1) The overall rigidity of the frame frame is good, the compressive strength is high, and the pressure, stroke, and pressure preservation can be adjusted according to the requirements of the pressing process.

(2) With lower top material, upper material and upper, lower composite top material or shallow drawing and other different derivative models, suitable for a variety of pressing forming process needs.

(3) The pressure after closing is fast, and it takes only a few seconds to reach the rated pressure.

(4) The use of lower fuel tank, easy to replace and clean the fuel tank.

(5) Stable mass production quality and reliable performance.

(6) Electrical control to microcomputer type single chip microcomputer, the advantages of the system is 24V safety control voltage, there is no intermediate relay, no contact, the stability of the whole computer chip, long service life, simple operation, a wide range of grating safety protection devices.

Working principle

The hydraulic pump is the power source of the hydraulic system, and it is the force that makes the hydraulic oil enter the cylinder piston through the hydraulic pipeline. There are several groups of seals in the cylinder piston that cooperate with each other, and the seals in different positions are different, but they all play the role of sealing, so that the hydraulic oil can not be exposed. Finally, through the check valve, the hydraulic oil in the injection box ring makes the oil piston cycle to do work to realize the energy conversion, regulation and transportation, and complete the cycle of various process actions. Hydraulic cylinder converts hydraulic energy into mechanical energy hydraulic 仮 motion is a transmission mode that uses liquid pressure to drive power and feed control Hydraulic device is composed of hydraulic pump, hydraulic cylinder, hydraulic control and hydraulic laying aid components.

Safe operation

1, start the equipment pressure test, check whether the pressure reaches the working pressure, whether the equipment action is normal and reliable, there is no leakage phenomenon.

2, adjust the working pressure, but should not exceed 90% of the rated pressure of the equipment, the pressure test workpiece, after the inspection and then production.

3. For different hydraulic profiles and workpieces, when pressing and correcting, the working pressure and pressure of the press, the number and time of pressure holding should be adjusted at any time, and the well should ensure that the mold and workpieces are not damaged.

4. When the body pressure plate is sliding up and down, it is strictly prohibited to put the hand and head into the working part of the pressure plate and the mold.

5, it is strictly prohibited to carry out enemy attack, stretching, welding and cutting, snow pressing, twisting and other operations on the work at the same time.

6, hydraulic press press edge shall not smoke, welding and cutting, fire, shall not store flammable and explosive items, do a good job of fire prevention measures.

7. After the hydraulic press is finished, the power supply should be cut off, the hydraulic rod of the press should be wiped clean, the lubricating oil should be added, the molds and workpieces should be cleaned and placed neatly.
