1. What is a Four Column Three Beam Hydraulic Press?

The Four Column Three Beam Hydraulic Press, also known as Three Beam Four Column Hydraulic Press, is a kind of hydraulic processing equipment based on Pascal's principle, which uses hydraulic oil as the working medium to transmit pressure and complete various pressing processes. Its name comes from its unique structural design: three beams (upper beam, movable beam and workbench) and four guide columns form a closed frame structure, which can evenly bear the pressure generated during the working process and ensure the stability and precision of the equipment during high-load operation.

Different from other types of hydraulic presses, the Four Column Three Beam Hydraulic Press has the characteristics of simple structure, reasonable force, easy operation and wide application range. It can be customized according to the actual needs of users, such as tonnage, stroke, workbench size, etc., to meet the processing needs of different workpieces and industries. As a key equipment in modern manufacturing, it plays an important role in improving production efficiency, ensuring product quality and reducing production costs.

2. Structural Composition of Four Column Three Beam Hydraulic Press

The Four Column Three Beam Hydraulic Press is mainly composed of three parts: main machine, hydraulic control system and electrical control system. Each part cooperates closely to ensure the stable and efficient operation of the equipment.

2.1 Main Machine (Host)

The main machine is the core part of the Four Column Three Beam Hydraulic Press, which bears the main load during the pressing process and is responsible for completing the forming processing of workpieces. Its main components include:

• Three Beams: Including upper beam, movable beam and workbench (lower beam). The three beams are usually made of high-quality steel plates through CO2 shielded welding, and undergo tempering treatment to eliminate internal stress, which has high structural strength and rigidity. The end face modulus of the three beams is large, which can greatly extend the service life of the equipment. The workbench is used to place workpieces and molds, and its surface is processed with high precision to ensure the flatness of the workpiece during processing.

• Four Guide Columns: Made of high-quality 45# round steel, the surface is subjected to intermediate frequency quenching and hard chrome plating treatment, with high hardness (up to HRC45-50), wear resistance and corrosion resistance, which can prevent surface scratches and corrosion. The guide column is matched with the sliding sleeve (guide sleeve) made of wear-resistant cast iron, which is embedded with polytetrafluoroethylene metal composite material to ensure the smooth and stable movement of the movable beam along the guide column.

• Main Cylinder & Ejection Cylinder: The main cylinder is the power source of the equipment, which is usually installed on the upper beam. The piston rod and main cylinder are made of high-quality forgings, with high reliability. The ejection cylinder is installed under the workbench, which is used to eject the workpiece after processing, improving the efficiency of workpiece taking. The sealing of the main cylinder adopts imported or domestic high-quality seals to ensure the sealing performance of the hydraulic system and reduce oil leakage.

2.2 Hydraulic Control System

The hydraulic control system is the "power transmission center" of the Four Column Three Beam Hydraulic Press, which is composed of power devices, control components, executive components and auxiliary components. The system adopts an integrated cartridge valve system, which has the advantages of compact structure, reliable action, long service life, small hydraulic impact and fewer leakage points. The hydraulic oil pipeline adopts cold-drawn seamless steel pipe, with clear and neat layout, and obvious color difference between high-pressure and low-pressure pipes, which is convenient for maintenance.

The hydraulic system is equipped with a liquid filling tank with an increased volume, which can ensure rapid liquid filling, reduce pressure rise time, increase heat dissipation area and reduce oil temperature. At the same time, the system is equipped with oil temperature and oil level display, air filter and other devices to ensure the normal operation of the oil circuit. The power system adopts an oil-immersed vertical pump unit, which has the advantages of low noise, good oil suction effect and long pump service life.

2.3 Electrical Control System

The electrical control system is the "brain" of the Four Column Three Beam Hydraulic Press, which is mainly composed of electrical control cabinet, PLC controller, buttons, travel switches, etc. The system adopts centralized button control, which can realize three operation modes: manual, semi-automatic and automatic, and supports two forming processes: constant pressure and constant stroke, with pressure-holding delay function. The working pressure, stroke and speed of the slider can be adjusted within the specified range according to the process requirements, which is flexible and convenient to operate.

Some high-end models are equipped with touch-type industrial display screens, servo control systems and remote monitoring functions, which can realize real-time monitoring and adjustment of equipment parameters, further improving the automation level and processing precision of the equipment.

3. Working Principle of Four Column Three Beam Hydraulic Press

The working principle of the Four Column Three Beam Hydraulic Press is based on Pascal's law: in a closed system, the pressure transmitted by the liquid is constant. When the equipment is started, the electrical control system controls the hydraulic pump to start, and the hydraulic pump injects hydraulic oil into the main cylinder. Under the action of hydraulic pressure, the piston of the main cylinder drives the movable beam to move downward at a constant speed along the four guide columns. When the mold on the movable beam contacts the workpiece on the workbench, the pressure gradually increases to complete the pressing, forming, stretching, bending and other processes of the workpiece.

After the processing is completed, the hydraulic system controls the hydraulic oil to flow back, and the return cylinder drives the movable beam to return to the initial position. The ejection cylinder ejects the workpiece, and a working cycle is completed. During the working process, the travel switch feeds back the position signal of the movable beam to the electrical control system to realize cyclic control, ensuring the stability and consistency of the processing process.
