Taiyuan Heavy Industry Rail Transit Equipment Co., Ltd. (hereinafter referred to as "Taiyuan Heavy Industry Rail Company") successfully developed the world's largest cross wedge rolling machine and successfully completed the landmark "first rolling" test. This major achievement not only demonstrates the outstanding strength of Taiyuan Heavy Industry Rail Company in the field of high-end equipment manufacturing, but also marks a new breakthrough in large-scale shaft forming technology in China. It is a great honor for Qingdao Huachuang Xia Feng to participate in the national key research and development program "National Robot" key special project, large-scale shaft wedge cross rolling robot production line and its application demonstration project kick-off meeting.

The picture shows Mr. Xia feng (from the front to the back, two rows and seven from the right) participating in the national key research and development plan "national robot" key special project, the launching meeting of the large-scale shaft wedge cross rolling robotic production line and its application demonstration project.

This giant cross wedge rolling machine was jointly developed by Taiyuan Heavy Industry Rail Company after years of scientific research and technology accumulation, in conjunction with Beijing University of Science and Technology, Taiyuan University of Science and Technology and other well-known universities. With a height of more than 7.5 meters, a roll diameter of 1.7 meters and an overall weight of more than 600 tons, the equipment is currently the largest and most technologically advanced cross wedge rolling mill in the world.

In the "first rolling" test, this giant cross wedge rolling machine successfully produced a large railway axle with a diameter of 220mm, a length of 2400mm and a weight of 540Kg. This result not only created the world record for the largest specification of cross wedge rolling shaft parts, but also verified the strong ability of the equipment in the field of large shaft forming.

Behind this successful "first rolling" is Taiyuan Heavy Industries Rail Company's continuous investment in technology research and development and process innovation. In the process of research and development, the company has overcome a number of technical problems, including the precision machining of large rolls, the research and development of high-precision control systems, and the heat treatment of high-temperature alloy materials. These technological breakthroughs not only improve the overall performance of the equipment, but also provide a solid technical support for subsequent manufacturing.

In addition, Taiyuan Heavy Industry Rail Company also pays attention to the exchange and cooperation with international advanced technology. In the process of research and development, the company actively introduces foreign advanced manufacturing technology and equipment, and has established close cooperative relations with many universities and scientific research institutions to jointly promote the research and development and application of cross wedge rolling technology. This open innovation model not only accelerates the process of technology research and development, but also enhances the company's overall competitiveness.

Regarding the successful "first rolling", Taiyuan Heavy Industry Rail Company stated that this will be an important milestone in the company's development history. In the future, the company will continue to increase scientific and technological innovation, continue to promote the development and application of cross wedge rolling technology, and make greater contributions to the development of my country's rail transit equipment manufacturing industry. At the same time, the company will also actively participate in international cooperation and exchanges to promote China's rail transit equipment manufacturing industry to the center of the world stage.

The successful development of the world's largest cross wedge rolling machine and the successful completion of the "first rolling" not only demonstrates the strength of Taiyuan Heavy Industry Rail Company in technology research and development and process innovation, but also reflects the global leadership of my country's rail transit equipment manufacturing industry. position. The achievement of this achievement will inject new impetus into the development of China's rail transit industry and promote the optimization and upgrading of the relevant industrial chain.
