The role of forging equipment in national economic, social, and scientific development

The parts manufactured by forging equipment have the advantages of high productivity, high performance, and precision, and play a crucial role in the national economy, social development, and scientific development.

1. The need for the development of the new materials industry

New materials involve a wide range of fields, generally referring to newly emerged materials with excellent performance and special functions, or materials with significantly improved performance and new functions after the improvement of traditional materials. Mainly including high-quality special steel, new light alloy materials, etc. Most of these materials require forging equipment to achieve significant improvements in raw material properties, such as high-temperature, high-pressure, and corrosion-resistant power plant steel, nickel saving high-performance stainless steel, high standard bearing steel, gear steel, mold, and high-strength fastener special steel in high-quality special steel.

2. Requirements for high-end manufacturing industry

The high-end equipment manufacturing industry is a strategic emerging industry led by high-tech, located at the high-end of the value chain and the core link of the industrial chain, which determines the comprehensive competitiveness of the entire industrial chain. The large-scale and integrated development of forging parts is the direction of aviation forging technology and an important condition for achieving the integration of aircraft main load-bearing structures.

The manufacturing of large aviation forging parts cannot be separated from large forging equipment. The materials used for aerospace and satellite components are mostly lightweight, high temperature resistant, and difficult to deform alloys. The turbine discs of aviation engines need to be opened by extruders to meet their performance requirements.

3. Requirements for the New Energy Industry

New energy vehicles are one of the important branches of the new energy industry, and energy conservation and new energy vehicles have become the development direction of the international automotive industry. Lightweight is an important link in realizing new energy vehicles. Aluminum alloy material has become the best material for automotive lightweighting due to its light weight, high strength and stiffness. The Honda NSX in Japan uses 31.3% aluminum throughout the vehicle, and Ford has set a goal to achieve roughly equal usage of aluminum alloy and steel on the body by 2020. Most of these aluminum materials are used as extruded products, such as bumpers, windows, seats, etc. For composite panel box cars and refrigerated box cars, their front top rails, side top rails, front bottom rails, and other products are all made of aluminum alloy extruded profiles.

4. Automotive, railway, and shipbuilding industries

At present, the large forgings required by industries such as automobiles and railways, especially the crankshaft large forgings for heavy-duty vehicles, are produced by hammer forging or can only be replaced by castings. The development of a heavy-duty crankshaft hot forging production line can greatly improve production efficiency, reduce the forging cost of forging blanks, improve the forging performance of forgings, and meet the development needs of automobiles, railways, shipbuilding, and other fields.

5. Electrical appliances and home appliance industry

The processing of the vast majority of components in electrical appliances and household appliances is usually done by stamping several workpieces separately, and then welding them together. The huge output has forced the slider of the high-speed press to travel up to 4000 times per minute.

6. Power industry

At present, the total production of complete sets of traditional power equipment, including generators, steam turbines, and boilers, has reached two-thirds of the global total. Such a large electricity market requires the equipment manufacturing industry to constantly strive for progress and innovation. The use of large-scale free forging hydraulic presses greatly meets the urgent requirements for forging large free forgings in power equipment.
