Overview of performance and structure of frame hydraulic press

The hydraulic machine body adopts a frame structure: it is composed of upper beams, sliders, worktables, columns, main cylinders, hydraulic power systems and electrical systems. The upper beam, slider and worktable are welded with high-quality steel plates. After welding, the welding stress is eliminated by high-frequency vibration. The column of the hydraulic machine is high-quality 45# steel, and the surface is medium-frequency quenched and chrome-plated.

The tonnage of the pressing cylinder of the hydraulic machine is realized by a piston cylinder. The cylinder body is made of high-quality forged steel. The surface of the piston rod is quenched by intermediate frequency, which has high hardness and long service life. The main seals of the oil cylinder adopt high-quality sealing rings to ensure reliable sealing.

There are T-shaped grooves on the working table and slider of the hydraulic machine, which is convenient for the user to install the mold.

Hydraulic system of frame hydraulic press

The hydraulic system is installed on the right side of the fuselage of the hydraulic press.

The hydraulic system adopts a plug-in integrated system, which is sensitive, reliable, and has good sealing performance.

The pump station of the hydraulic press is composed of an oil tank, a high-pressure pump, an electric motor, a plug-in valve, etc. The oil tank is welded by steel plates. The oil tank adopts a closed type oil tank, the oil suction area and the oil return area are separated, and the oil tank is provided with a cleaning window and an oil drain plug, which makes cleaning and oil changing convenient. The oil pump suction port of the hydraulic machine is equipped with a straight-through oil suction filter to ensure the cleanliness of the oil and ensure the service life of the oil pump and valve.

The hydraulic system has a reliable seal and no leakage. The main pipeline of hydraulic machine adopts flange connection and anti-seismic pipe clamp.

Electrical control system of frame hydraulic press

Independent electrical cabinet with air switch, relay and other electrical control systems.

Various alarm signals of the press, the limit switch and the action of the press realize interlocking of the program.

The hydraulic press is equipped with a centralized control panel, and the necessary operation buttons and selector switches are arranged on the panel.

Operation method of frame hydraulic press

The press is equipped with jog and semi-automatic operation modes.

The stroke of the slider of the hydraulic machine is adjusted by a stroke control device.

In addition to completing all the actions of the press, the buttons on the operating platform should also have buttons such as "two-handed pressing", "return", "stop", and "emergency stop".

Safety protection device of frame hydraulic press

Set an emergency stop button, press the emergency stop button, the press immediately power off and stand still.

The slider is provided with limit switches at the upper and lower limit positions.

A hydraulic support fuse circuit is provided in the lower chamber of the piston oil cylinder.
