500 tons of three beamsfour-column hydraulic pressIt adopts four-column structure and uses hydrostatic pressure to process metal, plastic, rubber, wood, powder and other products. The frame of the fuselage is welded by high-strength steel. The surface of the fuselage is treated with rust prevention and painting, which is beautiful and can prolong the service life.
The working principle is based on Pascal's law, that is, the pressure change that occurs in a certain part of the stationary fluid in the closed container will be transmitted to the various parts of the fluid and the container wall without loss. When the hydraulic pump pressurizes the hydraulic oil, it is delivered to the hydraulic cylinder through the control valve group to push the piston to move. The piston is connected with the worktable or the upper mold. When the piston moves, it will exert huge pressure on the workpiece placed on the worktable, so as to realize various processing technologies, such as stamping, stretching, bending, extrusion, etc.
In the metal processing industry, it can be used for metal sheet stamping, drawing, forging and other processes. For example, the manufacture of auto body parts, hardware tools, mechanical parts, etc.; in the plastic products industry, it is used for compression molding of plastic products, demoulding after injection molding, etc. Such as the production of plastic containers, plastic pipe fittings, plastic plates, etc. It can also be used in wood chip molding, powder metallurgy, composite molding and other fields.
The 500-ton hydraulic press adopts computer optimization design and is divided into four-column and frame structure. The four-column structure is simple, economical and practical. The frame structure has good rigidity, high precision and strong resistance to eccentric load. The hydraulic control system adopts a plug-in integrated system, which is reliable in action, long in service life, small in hydraulic impact, and reduces connecting pipes and leakage points. The electrical system controlled by CNC PLC is compact in structure, sensitive and reliable in operation and convenient in use and maintenance.
500-ton hydraulic press (stamping/drawing) is widely used in deep drawing process and can be used for deep drawing of stainless steel products. The forging process of 500-ton frame hydraulic press (cross shaft forging press) generally consists of selecting high-quality billet blanking, heating, forming, cooling after forging and other processes. The forging process methods include free forging, die forging and hot die forging.
The 500-ton hydraulic press is suitable for all stretching, bending and forming processes such as large automobiles, agricultural vehicle covers and other parts, as well as ships, aviation, aerospace and other fields; the hydraulic press can be applied to forging processing of different materials and shapes. Strong versatility and flexibility.
500-ton hydraulic presses can be divided into many types, such as 500-ton four-column three-beam hydraulic presses, 500-ton four-column four-beam hydraulic presses, frame hydraulic presses, etc.
The four-column hydraulic press adopts a four-column structure. The four-column combination nut and the upper beam, the slider beam, and the lower beam form a rigid frame. The overall stability is good, the four-column is guided, the accuracy is high, and the application range is wide. Among them, the four-column and four-beam hydraulic press has one more beam than the four-column hydraulic press, which is used for demoulding beams or edge-pressing beams, which can realize double action and simplify production.
It is widely used in the processing and molding of various materials, such as stretching, bending, flanging, cold extrusion and blanking of metal materials; pressing molding of powder products; pressing molding of plastic products, suitable for the molding and processing of various thermoplastics and thermosetting plastics; pressing molding of rubber products, suitable for the molding and processing of various rubber materials, etc.
The process flow of the 500 ton hydraulic press: 1. In the preparation stage, check whether the various parts of the hydraulic press are normal, including hydraulic cylinders, hydraulic pumps, control valves, electrical systems, etc., install the mold, select the appropriate mold and install it according to the requirements of the processing technology On the hydraulic press. Ensure that the mold is installed firmly, the positioning is accurate, the workpiece is prepared, and the workpiece to be processed is subjected to necessary pretreatment, such as cleaning, cutting, and shaping. Ensure that the workpiece meets the machining requirements.
2. Start the equipment, press the start button, start the hydraulic pump and electrical system, adjust the pressure, stroke, speed and other parameters of the hydraulic press according to the requirements of the processing technology, and place the prepared workpiece on the mold to ensure that the workpiece is placed smoothly and accurately. Press the operation button and the hydraulic press starts to work. The hydraulic cylinder pushes the mold to process the workpiece, such as stamping, stretching, bending, etc. During the processing, it is necessary to closely observe the operating status of the equipment to ensure the smooth progress of the processing process. 3. After the processing is completed, press the stop button to stop the hydraulic press.
