There are teeth on the rim of gear forgings, which can continuously mesh and transmit motion and power. The application of gear forgings in transmission has appeared for a long time. At the end of the 19th century, the principle of generating gear cutting method and the emergence of special machine tools and cutting tools using this principle. With the development of production, the stability of gear forging operation has been paid attention to. It is mainly used in mining machinery, petrochemical industry, automobile manufacturing and other fields. The main materials are 20CrMnTi, 40Cr, 42CrMo, etc.
Most middle and low-grade gear molds can be produced in China, and most high-end gear molds rely on imports. There are few factories specializing in gear molds in China, most of which are made by gear factories themselves. Gear factories often set up a section or workshop to undertake this work. This makes the development of domestic gear mold industry even more difficult. Relevant experts said that in order to promote the better and faster development of China’s gear mold industry, we must fundamentally solve the problem of dependence and strive to improve professional technology in order to better serve the domestic gear mold industry.
With the increasing competition in the gear forging industry, M & A integration and capital operation among large gear enterprises are becoming more and more frequent. Domestic excellent gear forging manufacturers pay more and more attention to the research on the industry market, especially the in-depth research on the change of enterprise development environment and customer demand trend. Because of this, a large number of domestic excellent gear brands rise rapidly and gradually become the leaders in the gear forging industry!
In 2011, the overall sales of gear forging industry reached 178 billion yuan, a year-on-year increase of 23%; Although the import volume is still much higher than the export volume, the export growth rate is significantly stronger than the import.
In 2012, the development of gear forging industry may show a trend of “first low, then high and medium speed growth”. The slowdown trend of industry growth in the fourth quarter of 2012 will continue to this year. In the second half of the year, with the gradual implementation of the national policy of expanding domestic demand, the development of strategic emerging industries and the implementation of the national “three base plan”, it is bound to improve the modern equipment manufacturing industry, so as to drive a new round of rise of the whole gear forging industry. It is estimated that the sales revenue of gear forging industry will increase by more than 10%, and the export growth may reach 15%. Yongxinsheng forging meets the national quality standards.
