Cold forging is a general term for plastic processing such as cold die forging and cold extrusion. Generally, forging without heating the blank is called cold forging. Cold extrusion is a net-shaping process with precise cutting and special lubrication processing, which has very high requirements on the forming speed, closing time, and forming force control of the equipment.

Hydraulic presses are the most common cold extrusion equipment. Zhengxi has been working in this field for many years and has accumulated a large number of application solutions, which can provide a complete automatic cold extrusion production line.

Successful cold extrusion production is the organic cooperation of various factors such as equipment molds, processes, automation, and lubrication. Hydraulic cold forging press equipment should have high strength, good rigidity, good precision, and high safety. Zhengxi has continuously developed and improved cold extrusion technology. At present, the position control accuracy of the cold forging press is as high as +0.01mm, the pressure control accuracy is as high as +0.05Mpa, and it can realize automatic mass production。

The cold forging hydraulic press of Zhengxi has high forming precision, strong stability, simple operation, high efficiency, and low scrap rate. At present, it is widely used in automobile, hardware, light industry, military industry, bicycle, motorcycle, electrical appliances, and other industries at home and abroad.

The Advantages of Cold Forging Press

1. Energy saving and emission reduction: hydraulic and electric control adopts intelligent servo energy-saving systems, saving 50%-70% of electricity.

2. Safe and precise: Each machine is equipped with an infrared safety grating to effectively protect the operator. Servo intelligent patented control ensures that the repeat positioning accuracy of the machine can reach ±0.03mm, and the pressure error is ±1%.

3. Low failure rate: Servo intelligent patented control system does not do useless work. The oil temperature is not easy to rise, and there is no negative pressure in the oil circuit system. The failure is greatly reduced and the service life of hydraulic components is extended. The electrical appliance is equipped with an automatic fault alarm and a one-button reset function.

4. Stable and durable: The frame adopts the whole machine frame structure, and the slider adopts a precision guide rail to guide the operation, which is strong in shock resistance and lateral pressure resistance. The whole machine is stable, precise, and durable, and is suitable for blanking, forming, extrusion, and other technological purposes.

5. Convenient maintenance: The whole machine is designed into a modular structure according to different functional modes, which is easy to disassemble and assemble. General faults can be viewed directly through the touch screen, and maintenance is simple.

1. The frame is a welded frame structure. The force condition is reasonable, the design safety factor is high, and the service life can reach more than 15 years.

2. Under full load, the table deformation is only 0. 5~1mm/m, ensuring high precision suppression.

3. The main cylinder adopts the international advanced anti-leakage composite sealing technology and metal expansion ring sealing technology, which can greatly improve the reliable life of the cylinder seal.

4. The cylinder piston adopts advanced composite bimetal welding technology, which improves the wear resistance and reliable life of the cylinder. And the service life can reach more than 30,000,000 times.

5. Fast cylinder technology can realize no power and rapid down, improve work efficiency and save energy.

6. The servo oil pump system combines the fast step-less speed regulation characteristics of the servo motor and the self-regulating oil pressure characteristics of the hydraulic oil pump, which brings huge energy-saving potential. And the energy-saving rate can reach up to 30%-80%.
