Heavy-duty die forging press has a good future

Heavy-duty die forging presses are mainly used for hot die forging and isothermal superplastic forming of refractory materials such as aluminum alloys, titanium alloys, superalloys, and powdered alloys. Its forging characteristics are that it can improve the density of the shaped material through high pressure, long pressure holding time, and slow shaping speed, and use the refined material grains to mobilize the overall function of the forging, mobilize the whole body forging. Uniformity, making difficult-to-form materials and complex structural forgings meet the design requirements through isothermal forging and superplasticizing, saving 40% of materials and achieving the goal of less machine polishing or near-net shape. The isothermal die forging hydraulic press is an important facility for the production of key forgings for aerospace, aerospace, aerospace and other key machines.

In order to mobilize the group performance of aerospace products, the proportion of heavy die forging press parts in aerospace forgings and the proportion of single parts are increasing. However, the existing die forging presses in the country are small in tonnage and relatively closed in technology. Most aerospace die forgings such as frame beams use cold welding structures. However, it is impossible to achieve grouping and cannot fully meet the requirements of heavy-duty airliners for overall performance, reliability and furnace age.

Because of the rapid development and application of high-temperature alloys, high-strength alloy steels and titanium alloys, and the development of important tie rods required in aerospace, aerospace, and nuclear energy industries to heavy-duty group die forging and precision die forging, there are many people in the country today. Products that require multi-directional die forging, because there is no habitual skill, it will only be changed to forging or free forging, or entrance. Heavy-duty die forging presses with a working pressure in the range of 50,000 to 80,000 tons are required to polish such forgings.

"Double" is one of the key production bases for heavy-duty die forging presses in the country. With 30 years of material discussion and production experience, it has successively provided more than 400,000 aerospace die forgings for the national aerospace industry, and the products cover all domestic models. . The construction project of the heavy-duty die forging press funded and constructed this time can solve the bottleneck of the blank manufacturing of industrial heavy-duty group structural parts such as aerospace, promote the digestion, absorption and innovation of the manufacturing skills of heavy-duty die forgings, and be the prerequisite for the development and manufacture of heavy-duty airliners across the country. The supply and demand of heavy die forging press commodities in the civil industries such as machine manufacturing, petroleum, chemical industry, and power. The implementation of the project has key tactical significance in adjusting the passive overall situation of heavy die forgings in the country depending on the entrance and being controlled by others, and realizing the independent manufacture of heavy die forging products.

All sources tell us that the heavy die forging press market has a good future. According to research and analysis, the annual supply and demand of various commodities suitable for heavy-duty die forging presses is about 4 billion yuan; and the built 80,000-ton heavy-duty die forging press production line has a comprehensive ownership rate of various commodity markets around 50%, with an annual output of about 50%. The capacity is about 2 billion yuan.

The research and development of heavy-duty die forging presses must focus on independent development; at the same time, we must adhere to the open technical strategy to the outside world. The heavy-duty die forging press designed by Erzhong, the Academy of Mechanical Engineering and other units jointly tackles key problems. The heavy-duty die forging press has a light body structure, high reliability and safety in the hydraulic system, and the electrical control system can be automatically operated according to the preset process curve. Features such as online monitoring of the working conditions of the press, set off the technological level of today's progress in the world. The construction and production of the heavy die forging press will greatly mobilize the international competitiveness and international reputation of the national equipment manufacturing industry.
