Introduction of hydraulic press

Hydraulic press master cylinder
The cylinder body is made of high-quality 45# steel, and the surface of the piston rod is treated by intermediate frequency quenching, which has a long service life. The main components of the oil cylinder adopt high-quality material sealing ring to ensure reliable sealing
Hydraulic system
A large flow cartridge valve is adopted, and an oil suction filter is arranged at the oil inlet of the pump to prevent impurities from entering the hydraulic system to ensure the normal operation of the oil circuit. The system has oil temperature and oil level display, air filtration and other devices. The oil tank is of steel plate welded structure, and the bottom is equipped with screw plugs for oil drain and sewage discharge. Plug-in hydraulic special motor to reduce workshop noise
Electrical system
The machine is equipped with an independent electrical control box to centrally control the operation of the entire machine. The equipment is equipped with photoelectric protection device and emergency stop button to ensure the safety of personnel and equipment during operation.
Operating System
PLC programming system is adopted to realize free switching of automatic and semi-automatic operation modes, which is convenient for equipment maintenance. The operating speed of the equipment and the pressure of the master cylinder can be adjusted arbitrarily. Meet the process requirements of fixed range and pressure during production.
本机为巴基斯坦客户采购的400吨四柱液压机，采用双缸设计结构，According to customer process requirements, can be equipped with top cylinder, hydraulic pad for stretching parts. You can also add a configurationUsed for stamping and forming of auto parts, hot molding of glass fiber reinforced plastic composite materials, etc. The equipment is also suitable for the pressing process of plastic materials,Such as blanking, bending, flanging, sheet stretching, etc., can also be engaged in correction, press fitting, grinding wheel forming, cold extrusion metal parts forming, plastic products及粉末制品的压制成型工艺，配上冲裁缓冲装置后可用于冲孔、落料加工。众友重工一般根据客户工件需For tailor-made design. About the equipment 400 tons four column hydraulic machine price, detailed parameters and other information, welcome to call all friends heavyWork

1. The whole steel plate welding frame type rack, the overall rigidity is good, the compressive strength is high;
2. The pressure, stroke, holding pressure, etc. can be adjusted according to the requirements of the pressing process;
3. With different derivative models such as lower top material, upper material and upper and lower composite top material or shallow drawing, it is suitable for the needs of various pressing forming processes;
4. After the mold is closed, the pressure is fast, and it only takes a few seconds to reach the rated pressure;
5. The use of under-mounted fuel tank, easy to replace and clean the fuel tank;
6. After more than ten years of mass production, stable quality and reliable performance.
7. This machine is equipped with fast oil cylinder, and optional material withdrawal device, photoelectric protection, etc.
