On November 19, the reporter learned from Wuhan Newwish Technology Co., LTD., that the servo direct drive electric screw press independently developed by the company and the world's largest tonnage was delivered in Shaanxi, which will be used to produce key components such as fan blades for aircraft engines.

Aeroengine fan blades need to operate stably and continuously under the harsh conditions of high temperature, high pressure and high speed, which requires very high material properties, geometric accuracy and manufacturing process. The strength and accuracy of the forging equipment are directly related to the yield and production efficiency of the blades.

"The nominal pressure has reached 6,300 tons, and the peak torque of the self-developed permanent magnet synchronous ring motor can reach 252,000 N · m, and these two key performance indicators have reached the international leading level." According to the relevant person in charge of New Vich, with the self-developed numerical control system, the press can accurately control the attack energy and deformation rate in the forging process, and is a "strong man capable of embroidery".

Xinweiqi was founded in 1993 by Huang Shuhuai, former president of Huazhong University of Science and Technology. In 2003, New Wich successfully developed the first domestic electric screw press, breaking the monopoly of foreign brands in this field. This month, the screw press independently developed by New Vich was delivered to Japanese customers, achieving reverse export to the industrial mother machine power. Up to now, the company has delivered more than 1,800 forging equipment, built more than 150 automatic forging lines, and served more than 500 users.

On November 19, Changjiang Daily reporter learned that Wuhan Newwish Technology Co., LTD. (hereinafter referred to as "Newwish") successfully delivered China's first and the world's largest tonnage J58ZK-6300 servo direct drive CNC electric screw press to Shaanxi Changyu Aviation Equipment Co., LTD. It will be used in the manufacture of key components of aeroengines such as large fan blades.

As the largest blade in the engine, the aero-engine fan blade undertakes the critical task of pushing large amounts of air into the engine and providing more than 80% of the total thrust, and its size and complex structure determine the extremely high requirements for material properties, geometric accuracy and manufacturing processes. The J58ZK-6300 servo direct drive electric screw press independently developed and manufactured by Newwish realizes the near-net forming and efficient forging of large-size fan blades with its high precision, strong forming force and flexible production capacity, filling the gap in this field in China.

According to the report, the nominal pressure of the equipment reached 63,000 kN, long-term allowable load 100,000 tons, the use of split cast steel combination fuselage, nearly 11 meters high, the application of self-developed large torque permanent magnet synchronous ring motor direct drive, to achieve zero transmission, no noise, maintenance-free, matching self-developed special CNC system, The striking energy, deformation rate and slider position in forging process can be accurately controlled. The combination of large tonnage and high precision solves the contradiction between high-end forging accuracy and forming efficiency. "The design and performance indicators have reached or partially exceeded similar products at home and abroad, reaching the international advanced level." The relevant person in charge of Newwish said.

Newwish was founded in 1993 by Professor Huang Shuhuai, former President of Huazhong University of Science and Technology. In 2003, Newwish successfully developed the first domestic electric screw press, filling the domestic gap. Since then, the company has accelerated toward industrialization, and has launched a series of high-end equipment such as servo direct drive electric screw press, die forging CNC servo hydraulic press, etc., to meet the domestic market demand at the same time, but also exported to Japan and other countries.

This is another breakthrough in the field of high-end equipment manufacturing achieved by this state-level specialized and newly focused "little giant" enterprise after the successful development of the first domestic 4000 tons servo direct drive CNC electric screw press and 1000 tons CNC servo hydraulic flat forging machine in 2023. The person in charge said: "The successful development of J58ZK-6300 servo direct drive electric screw press, while promoting the development of high-end aviation manufacturing technology, but also for China's advanced manufacturing equipment to provide a domestic alternative."
