The four-column hydraulic oil press consists of two parts: the main engine and the control mechanism. The main part of the hydraulic press includes the fuselage, the main cylinder, the ejector cylinder and the liquid filling device. The power mechanism consists of a fuel tank, a high-pressure pump, a low-pressure control system, an electric motor, and various pressure valves and directional valves. Under the control of the electrical device, the power mechanism realizes the conversion, adjustment and delivery of energy through pumps, oil cylinders and various hydraulic valves, and completes the cycle of various technological actions. Hydraulic cylinder: Converting hydraulic energy into mechanical energy Hydraulic transmission is a transmission method that uses liquid pressure to transmit power and control. The hydraulic device is composed of hydraulic pump, hydraulic cylinder, hydraulic control valve and hydraulic auxiliary components.
This series of products are suitable for pressing processes of various plastic materials, such as stamping, bending, flanging, etc. It can also be used for calibration, press fitting, grinding wheel forming, plastic products, rubber products and powder products.
The mainframe of this series of products adopts a three-beam four-column structure, the hydraulic system adopts a cartridge valve oil circuit, and the electrical system adopts a relay to form a PLC control circuit, which has adjustment and semi-automatic operation modes. Long service life, small hydraulic impact force, reducing the connection pipeline and leakage.
The working pressure, pressing speed and stroke range of this series of products can be adjusted within the specified range according to the process needs, and two process modes of constant pressure and fixed stroke can be realized. During constant pressure molding, there is a pressure holding delay and automatic return after pressing. There is an ejection device in the middle of the worktable. In addition to ejecting products, there is a molding process used as a hydraulic pad for stretching.
The working pressure and stroke can be adjusted within the specified range according to the process needs. Applicable fields: This series of presses are suitable for deep drawing, bending, flanging, cold extrusion, blanking and other processes of metal materials. compression molding.
