400 Ton Four-Column Hydraulic Cushion Stretching Hydraulic Press for Stainless Steel Fan Housings Production
The hydraulic cushion stretching hydraulic press is a commonly used type of stretching machine, suitable for the deep drawing process of metal sheets. This 400-ton four-column hydraulic cushion stretching hydraulic press is a popular model specifically designed for the stretching forming of stainless steel fan housings. It adopts a three-beam four-column structure, where an additional hydraulic cushion device is placed beneath the worktable based on the three-beam four-column structure. The hydraulic cushion, also known as a multi-ejector mechanism, evenly distributes some ejector rods on the worktable according to the size of the product. The placement of hydraulic cushion ejector rods corresponds to the shape of the product, ensuring uniformity in the stretched products.
Stretching Principle of 400 Ton Four-Column Hydraulic Cushion Stretching Hydraulic Press:
A slider pushes the upper die to press the thin plate to the lower die, forming the desired shape. However, in practice, it is a complex process. In the forming process, the deep drawing hydraulic cushion is the relative moving component of the slider. Therefore, their movements must be accurately coordinated to ensure precise forming force requirements.
The 400-ton four-column hydraulic cushion stretching hydraulic press adopts a three-beam four-column structural form, composed of upper beam, slider beam, worktable, hydraulic cushion plate, ejector rod, oil cylinder, column, oil tank, limit mechanism, etc. The hydraulic press comes with a PLC programmable controller and a touchscreen, allowing users to intuitively view data and make timely adjustments. The operation buttons of the hydraulic press are integrated on a movable button control platform that can be freely moved within a certain distance range, facilitating operation. The 400-ton four-column hydraulic cushion stretching hydraulic press adopts PLC automatic control and can operate in manual, semi-automatic, and automatic modes. The working pressure, pressing speed, and stroke range of the machine can be adjusted according to process requirements. The slider can stop at any position during operation. The three-beam four-column structural form makes the overall structure simple and aesthetically pleasing. The hydraulic system uses cartridge valves, ensuring a compact structure, sensitive and reliable operations, and facilitating diagnosis and troubleshooting of faults. It is suitable for the stretching process of metal thin sheets and the pressing process of plastic materials. The machine has an independent power mechanism and electrical system.
The workpieces produced by this 400-ton four-column hydraulic cushion stretching hydraulic press have small diameter tolerances, smooth stretching surfaces, and neat cut surfaces. Customers have expressed satisfaction with the machine. The body of the machine is placed above the hydraulic station, effectively reducing the footprint. Dual hydraulic cylinders support the machine, ensuring concentrated pressing force and avoiding off-center loads. It is suitable for the stretching forming of stainless steel thin sheets and other workpieces with deep or shallow stretching processes, as well as bending, flanging, and blanking processes. The machine is versatile, requiring only mold replacement for different applications. This 400-ton four-column hydraulic cushion stretching hydraulic press is also suitable for the production of aluminum, copper products, and stainless steel, thin iron, and other products.
