The four-column hydraulic press has excellent performance and a wide range of applications. It is a relatively common model. It uses four high-strength columns as the guiding mechanism to ensure the stability and accuracy of the machine under high pressure. The mold installation and adjustment are convenient and quick. The carrying capacity and anti-partial load capacity of the equipment are improved. The overall steel plate welding enhances the rigidity and stability of the machine and is suitable for processing multiple types of workpieces. It ensures the reliability and durability of the equipment under long-term and high-load operation.
Equipped with advanced hydraulic system, the use of integral cartridge valve set system, reducing the leakage point, improve the sealing and reliability of the system, hydraulic components with precision to ensure that the pressure, speed and other parameters of the precise adjustment, to meet the needs of different processes, the use of PLC (programmable logic controller) control, compact structure, sensitive and reliable work.
It is suitable for the processing of metal, plastic, rubber, wood and other materials, as well as stretching, stamping, bending, forming and other processes. It has a wide application prospect in industrial production.
The four-column hydraulic press is mainly composed of the key components such as the upper beam, the slider (the guide rail slider), the workbench, the four columns and the hydraulic system.
The upper beam is used as the support structure of the hydraulic cylinder and the main force-bearing parts. It is forged from high-strength cast steel or forged steel parts. It has good rigidity and compressive strength. It has undergone precision processing and heat treatment to ensure that it is in line with the hydraulic cylinder and other parts. Accurate fit.
Driven by the hydraulic cylinder, the guide slide block moves up and down along the column to complete the pressing and stretching of the workpiece. High-strength cast steel or forged steel parts are used, and the surface is specially treated to improve wear resistance and corrosion resistance. The movement accuracy of the slide block is controlled by four precision guide sleeves to ensure the vertical accuracy and the parallel accuracy of the lower working surface and the upper working surface.
The worktable is used to support and fix the workpiece to ensure the stability and accuracy of the workpiece in the processing process. The design of the worktable needs to consider the shape, size and processing requirements of the workpiece to ensure the smooth progress of the processing process.
Equipment inspection to ensure that the parts of the four-column hydraulic press are intact, the materials are prepared, and the raw materials to be processed (such as metal plates, plastic parts, etc.) are placed on the workbench.
Work cycle process: start the equipment: start the four-column hydraulic press through the operation panel and enter the standby state.
Slider descent: The hydraulic cylinder pushes the slider down quickly along the column, and the speed slows down when approaching the workpiece to avoid impact.
Pressure forming: After the slider is in contact with the workpiece, the hydraulic cylinder continues to apply pressure to make the workpiece plastically deform in the mold to reach the required shape and size. In this process, it may be necessary to maintain a certain pressure and time to ensure the quality of the workpiece.
Pressure relief return: after the completion of pressure molding, the hydraulic cylinder pressure relief, the slider quickly back to the initial position. At this time, the mold is opened and the processed workpiece can be removed.
Paying and blanking: The operator removes the processed workpiece from the mold and places it in the designated position. At the same time, prepare the next batch of raw materials for blanking.
The four-column hydraulic press is versatile, suitable for the processing of metal, plastic, rubber, wood and other materials, as well as stretching, stamping, bending, forming and other processes, and has a wide range of applications in industrial production.
