200-Ton Frame-Type Hydraulic Press from China Suppliers - Reliable Factory for High-Quality Press Machines

Structural Composition

• Main Machine Part: It includes the fuselage, main cylinder, ejection cylinder and liquid filling device, etc. Among them, the fuselage adopts an integral welded frame structure made of steel plates, which ensures the overall rigidity and compressive strength.
• Power Mechanism: It is composed of an oil tank, high-pressure pump, low-pressure control system, electric motor, and various pressure valves and directional valves, etc. It provides power for the hydraulic press and controls the flow direction, pressure, and flow rate of the hydraulic oil.
• Control System: PLC control is mostly adopted, which can realize two forming processes of constant pressure and constant stroke, has a pressure maintaining and time delay function, and the time delay can be adjusted. It can also control the working sequence of the hydraulic actuators.
• Non-metal processing industry: It can be used for the processing of non-metal parts, such as the pressing of, locks, and hardware parts, the press-fitting of electronic connectors and electrical parts, and related processes in the rubber and mold industries.

Working Principle

The mechanical energy is converted into hydraulic energy through the hydraulic pump, and the hydraulic oil enters the cylinder/piston through the hydraulic pipeline. The seals in the cylinder/piston prevent the leakage of hydraulic oil. Finally, the hydraulic oil circulates in the oil tank through the check valve, and the cylinder/piston does work cyclically, converting the hydraulic energy into mechanical energy to achieve various technological actions, such as pressing, stretching, and bending.

Characteristics

• Performance Aspect: The pressure and stroke can be adjusted according to the process requirements within the specified range. After the mold is closed, the pressure rises quickly, and it only takes about 1 second to reach the rated pressure. It has a high speed, low energy consumption, low noise, and can also realize the pressure maintaining function.
• Structural Aspect: The frame-type rack with integral welded steel plates has good rigidity and high compressive strength. The design of the lower-mounted cylinder makes the replacement and cleaning work convenient.
• Functional Aspect: Various derivative models such as lower ejector, upper ejector, and upper and lower composite ejector can be optionally equipped to meet different production process requirements.

Application Fields

• Metal Processing: It is used for processes such as forging, stamping, stretching, bending, and straightening and correction of metal parts, such as the processing of automotive parts, flanges, pulley discs, bushings, bearings, etc.
• Hardware Manufacturing: It is widely used in the production of hardware products such as watch cases, watchbands, eyeglass frames and their components, photo frames, tableware, nameplates, locks, etc.
• Other Industries: It is also applied in industries such as composite material molding, powder metallurgy, ceramics, rubber machinery, woodworking machinery, etc. For example, it is used for the hot pressing molding of composite materials and the pressing molding of powder metallurgy.

Maintenance

• Daily Maintenance: Check the hydraulic oil level and oil temperature, ensure that the hydraulic oil is clean and there is no leakage. Check whether the connecting bolts of each component are loose and whether the guide rails are well lubricated. Clean the dust and sundries on the surface of the equipment.
• Regular Maintenance: Replace the hydraulic oil and filter element regularly, and clean the oil tank and filter. Check components such as the cylinder seals, oil pipes, and joints. If there is wear or leakage, replace them in time. Check and maintain the electrical system of the equipment to ensure the normal operation of the electrical components.
