1、 Equipment Structure Description

This machine is a vertical structure four column three beam hydraulic press. The main cylinder stroke limit device of the aircraft body is connected through pipelines and electrical systems to form a whole. The following is a brief introduction of each part:

1. Body

The fuselage is composed of an upper crossbeam, a movable crossbeam, and a lower crossbeam connected by four columns, which are tightened with nuts to form a closed steel frame to withstand the force of the hydraulic press during operation. The moving beam is connected to the main cylinder piston rod flange and moves up and down guided by the columns. The upper crossbeam, movable crossbeam, lower crossbeam, and hydraulic pad are integral welded components.

The sliding parts of the moving beam are equipped with oil filling holes, and oil is added regularly to lubricate the moving parts.

2. Travel limit device

The travel limit device consists of a guide plate and a travel switch. Divided into three groups: upper limit switch, lower limit power switch, and fast/slow switch. Adjusting different switch positions can change the stopping position of the movable crossbeam at the upper and lower ends. After adjustment, the locking nut should be tightened. In constant pressure molding, the lower switch can only control the lower limit position (for protective purposes) and cannot control the compression stroke; In fixed distance molding, the travel switch plays a role in overpressure protection. The lower cylinder is composed of a lower cylinder upper limit switch and a lower cylinder lower limit switch. Ensure that the lower cylinder reaches the set position and stops.

3. Oil cylinder

The cylinder body of the oil cylinder is forged, drilled, and ground into shape. The material of the piston rod is forged 45 #.

4. Hydraulic system

The hydraulic system consists of a hydraulic transmission and control system. Mainly composed of fuel tank, oil pump, plug-in valve, cooling, filtration, etc. Control the electromagnetic directional valve through the electrical system to achieve various actions of the press.

(1) Fuel tank

The fuel tank is a welded steel plate component. The surface and interior have undergone strict slag removal and acid washing treatment. The edge of the fuel tank should be raised above the cover plate to prevent the oil from being exposed.

(2) Plug in valve

Adopting BCV series plug-in valve assembly, the structure is simple and compact, with fast response, small internal leakage, high flow rate, anti pollution, easy maintenance, and long service life.

(3) Pressure gauge

This machine uses an earthquake resistant oil pressure gauge with high display accuracy and is not easily damaged. The electric contact pressure gauge constantly detects the pressure in the upper chamber of the master cylinder, stops pressing when the set pressure is reached, and achieves a constant pressure return.

(4) Pressure safety

The plug-in valve itself has a pressure adjustment system, and if the pressure exceeds the set value, it will overflow and return oil. Keep the system consistently within the set pressure to achieve overpressure protection.

2、 Electrical system

1. The electrical system consists of a power system and a control system.

The power system consists of a main control device and an electric motor.

2. Operation method

Jogging, automatic.

The instruction manual is accompanied by an electrical schematic diagram.

3、 Machine execution standards

1. Hydraulic press design and manufacturing shall comply with JB3818-1999 "Technical Conditions for Hydraulic Press"

2. The safety of hydraulic presses shall comply with JB3915-85 "Safety Technical Conditions for Hydraulic Press"
