Recently, Zhongshan Wanda Machinery welcomed a Russian customer to visit. Accompanied by the company's agents, the two parties conducted special negotiations around a 20,000-ton ultra-high-pressure steel wire winding hydraulic press cooperation project to accurately meet the development needs of Russia's new energy and aerospace industries. They reached a preliminary consensus on cooperation details and future planning, laying the foundation for deepening the coordinated development of China and Russia's high-end equipment fields. This negotiation focuses on core equipment application scenarios. Our series of ultra-high-pressure steel wire winding servo CNC cold and hot forging hydraulic presses are suitable for precision cold forging, hot forging, drawing, hot and cold extrusion molding of aluminum alloy wheels, pan heads, various types of carbon steel, stainless steel, copper, aluminum, magnesium, titanium, nickel and other alloy materials, precision blanking, blanking, punching, bending, flanging and correction and leveling of large structural parts of various metal materials and plastic materials. Widely used in military, aviation, aerospace, new energy, photovoltaic, household appliances, automobile and motorcycle accessories, hardware and other industries. In line with Russian new energy,

As a core device in high-end industries such as new energy, GBT’s copper-based heat sink’s accuracy and performance are crucial. Wanda Machinery's precision cold forging production line specially built for this component has become a reliable support for the mass production of IGBT radiators with its mature and stable equipment configuration. The core of the production line consists of a 5,000-ton ultra-high-pressure servo cold forging hydraulic press, a 200-ton frame-cutting hydraulic press, and a 30-ton column-cutting hydraulic press, forming a complete closed loop of 'forming-finishing-subdivision', with all links seamlessly connected to ensure production efficiency and stability.

The working speed of the hydraulic press is significantly slower than the return speed. This is not because it is technically impossible to achieve high speed, but because it is an active design trade-off based on power balance and molding process requirements. The core logic revolves around the inherent constraints of the hydraulic system 'pressure-flow-power' and is combined with the core demands of its industry application scenarios. The following is a detailed analysis from the four dimensions of principle, difference comparison, design consideration and application adaptation: 1. Core principle: 'Power Balance Law' of the hydraulic system The operating speed of the hydraulic machine is directly determined by the flow rate of the hydraulic oil (the greater the flow rate, the faster the actuator is pushed), and the core constraint of the system comes from the power limit of the hydraulic pump. The relationship can be expressed intuitively through the formula: Pump power (P) = Working pressure (p) × Flow (Q) (Note: The formula is a simplified model, the actual system efficiency needs to be considered, but the core logic is the same) The rated power of the hydraulic pump is a fixed value (determined by the motor power), so 'pressure

The 10,000-ton large-scale ultra-high-pressure steel wire winding hydraulic press has an opening height of 3,000mm, a slider stroke of 1,600mm, and a parallelism of two planes of 0.02mm. The entire machine is about 10 meters high and weighs about 300 tons. .

The return spring of the reversing valve of the hydraulic press not only has insufficient elasticity, but also has a skew phenomenon, causing the spool of the reversing valve to fail to return to its original position after a power outage. Therefore, the opening of the slide valve is too small, which throttles the oil passing through the reversing valve. The initial movement of the hydraulic cylinder is slow. When the temperature is low, the viscosity of the hydraulic oil is relatively high and the mobility is poor, resulting in the slow movement of the hydraulic cylinder. If the outside temperature is really too low, you can use a heater or corresponding insulation measures to increase the oil temperature at startup. The contamination of the oil should be checked; check whether dirt or colloid deposits are blocking the valve core or valve hole, and check the wear of the valve body. The throttling resistance in the control pipeline may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is interfered with. The control pressure of the hydraulic system of the hydraulic press is too low. The piston rod of the hydraulic press is stuck with the cylinder or the hydraulic cylinder is blocked. The way to cover it is to promptly replace the hydraulic oil with better viscosity and temperature resistance. If the outside temperature
