On September 26, 2019, the off-line ceremony of the 200MN large-scale electric screw press developed by ZHZJ Heavy Machinery Technology Group was held at the Aviation Forging Industry Base. With the sound of the rumbling hammer, a large precision forging product was officially produced under the forging pressure of the world's largest electric screw press, marking that Chinese forging products have entered the precision forging 3.0 era since then.
The equipment has the characteristics of high precision, high rigidity, high energy, large impact force, anti-eccentric load, precise and adjustable speed, multi-point ejection, high efficiency and energy saving, etc. It can realize all forging parameters can be controlled, stored, and repeatable. It is especially suitable for the production of large and medium-sized precision die forgings such as various types of fan discs, compressor discs, turbine discs, beams, frames, landing gears, etc., which are difficult to deform in aviation and aerospace, such as high-temperature alloys, titanium alloys, and ultra-high-strength steel materials. The aviation, aerospace and other high-end forging markets have strict requirements for process consistency. Its forging capacity can cover more than 80% of aircraft structural parts and almost all aero engine die forgings, and can take into account heavy-duty gas turbines, aerospace, and transportation. , Shipbuilding, electric power and other high-end forging market.
Large-scale die forging equipment is the foundation of an industrial power, and all countries in the world that have die forging press equipment of 35,000 tons or more are large manufacturing countries. The 200MN electric screw press is the largest forging equipment of ZHZJ over the past 50 years, and it is also the largest electric screw press in my country at present. It has the characteristics of high precision, high rigidity, high energy, high efficiency and energy saving, and is especially suitable for high temperature in aerospace and aerospace. For the production of large and medium-sized precision die forgings such as alloys, titanium alloys, and ultra-high-strength steel materials, its completion and commissioning will effectively enhance the production capacity of China's aviation basic forgings, and make aviation forging level one step closer to the world's popular list.
