A hydraulic press is a pressure processing machine that uses liquid static pressure to transfer energy to achieve the forming of metal and non-metallic materials. The core principle of a hydraulic press is to convert mechanical energy into liquid pressure energy through a hydraulic system, and then convert the pressure energy into mechanical energy through a mold to complete the processing.
Frame
Three-beam, four-column type: Consists of an upper crossbeam, a lower crossbeam, and two vertical columns, connected by preloaded nuts or tie rods to form a rigid frame. This simple structure offers excellent rigidity and is suitable for small and medium-sized hydraulic presses.
Single-column type: Compact but with less rigidity, it is suitable for small, low-pressure hydraulic presses.
Worktable and slide
Worktable: The hydraulic press is fixed to the lower crossbeam and is used to mount the lower die or directly place the workpiece.
Slide: The hydraulic press is connected to the column or frame via guide rails. Driven by a hydraulic cylinder, the slide moves up and down, with the upper die mounted on its lower surface. The closing action of the slide and worktable completes the workpiece forming process.
Guide Rails: Hydraulic presses utilize sliding or rolling guide rails to ensure slide movement accuracy and reduce friction. High-precision hydraulic presses may be equipped with hydrostatic guides, which achieve frictionless motion through oil film support.
Oil Tank and Piping
Oil Tank: The hydraulic press's oil tank stores hydraulic oil and dissipates heat. An oil filter is required to keep the oil clean.
Pipeline: Connects the various hydraulic components in the hydraulic press. High-pressure hoses or rigid pipes should be used, and sharp bends should be avoided to minimize pressure loss.
Cooler: Reduces oil temperature to prevent oxidation and deterioration.
Heater: Preheats the oil in low-temperature environments to ensure fluidity. Accumulator: absorbs pressure pulsation or replenishes instantaneous flow to improve system stability.
Control Circuit
Relay Control: Hydraulic presses utilize relay logic control, with actions triggered by buttons, limit switches, and other mechanisms.
PLC Control: Our hydraulic presses utilize a programmable logic controller (PLC), enabling complex logic control, parameter storage, and fault diagnosis.
Human-Machine Interface (HMI): The hydraulic press features a touchscreen interface that allows for setting parameters such as pressure, speed, and stroke, and displays system status.
