Computer optimized structure design, gantry structure, simple, economical and practical.

The hydraulic control adopts the cartridge valve integrated system, which has adjustable pressure, stable flow, reliable operation, long service life, and reduced connecting pipelines and leak points.

Independent electrical control system, reliable operation, intuitive movement and convenient maintenance.

Centralized control with buttons, with jog and semi-automatic operation

By operating the control device, two forming processes of fixed stroke and constant pressure can be realized, and functions such as holding pressure delay

The working pressure of the slide block, the rapid downward travel with no load, and the slow travel advance range can be adjusted according to process requirements.

Optional accessories for hydraulic presses:

Grating safety protection device

Stroke, pressure, time touch display system

PLC programmable controller

Blanking buffer device

Floating guide and rolling bracket for mold change

Various forms of mobile workbench

Heating and cooling device of hydraulic system

Various types of hydraulic cylinders

Fast stroke flushing device

Application areas of hydraulic presses:

This machine is suitable for the pressing process of plastic materials, such as blanking, bending, flanging, sheet stretching, etc., and can also be engaged in correction, press fitting, grinding wheel molding, cold extrusion metal parts molding, plastic products and powder products. Technology, with punching and buffering device, can be used for punching and blanking processing.

I. Overview of machine performance and structure

The machine adopts a gantry full steel structure, and the mechanical deformation is small after vibration aging treatment. The gantry hydraulic press table can move up and down, which greatly expands the opening and closing height of the machine and is more convenient to use. It consists of main cylinder, hydraulic power system and electrical system. The workbench is welded with high-quality steel to ensure reliability and durability.

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

Second, the hydraulic system

The hydraulic system is mounted on the right side of the fuselage.

The hydraulic system uses a plug-in integrated system, which is sensitive in movement, reliable in work, and good in sealing performance.

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

The hydraulic system is reliable and leak-proof. The main pipeline adopts flange connection and seismic pipe clamp.

Third, the electrical control system

Independent electrical cabinet with built-in electrical control systems such as air switches and relays.

Various alarm signals of hydraulic press, limit switch and press action realize program interlock.

With a centralized control panel, the necessary operation buttons and selection switches are arranged on the panel.

Fourth, the operation mode of the press

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

The stroke 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 "hand pressing", "return," "stop" and "emergency stop".

Five, security protection

Set emergency stop button, press the emergency stop button, the press will stop immediately.

There are limit switches at the upper and lower limit positions of the stroke.

A hydraulic support safety valve circuit is arranged in the lower cavity of the piston-type cylinder to ensure safety. At the same time, a hydraulic interlock circuit is set to ensure that when the support safety valve is not opened, the upper cavity of the master cylinder cannot output pressure.

Six, equipment working environment

Power supply: three-phase 380v 50HZ

Working environment temperature: 0 ~ 40 ℃
