First, China's forging industry development foundation and development course
In the early days of China's national industrial base is extremely weak, through the "one five", "two five" nearly l0 years of efforts, fully completed a preliminary scale of production of modern industrial manufacture. The 2O in the late 50's, our country has built the FAW Group, Kazakhstan, a drag, shaft, bearing and other plants. Formed a steam hammer, hot die forging machine and horizontal forging machine is the main equipment of the production line, so that this ancient forging forming technology has been rapid development in succession. The first production car made in China, the first 10000 ton hydraulic press, the first FQ - artillery, tanks, first the first aircraft, ships, and gradually began to expand to other areas. In the following decades, expands unceasingly along with raising the level of equipment manufacturing enterprises and production capacity, variety and quantity of the products have increased, the forging technology has been Further development.
Since the reform and opening up, rapid rise of the automobile industry, our country determined to develop the car for the main ideas. Precision plastic forming technology has been widely used in the production of all kinds of Automobile Forging, such as hot precision forging the differential case, bevel gear, cold forging ball head pin, cardan shaft and the transmission shaft, and the warm forging CVJ bell housing, sliding bush, etc., thus greatly enhance the China precision plastic forming technology.
Two, China's forging industry development status and trends
At present, China's forging industry even though there is a certain foundation, but did not fully grasp the core technology of high-end forging industry. In recent years, the output of domestic forging enterprises to increase exports increased year by year, and by virtue of forging production in the number of international won the "big country forging" Title, but not "forging power". The development and production of high-grade die forging products is still quite backward, forging core Aerospace mainly rely on import. According to statistics, high-grade automotive forgings products have 70% ~ 80% El. is also suitable for our country forging equipment supply lags behind, the main forging equipment is still in the friction press. Overall, China forging industry, precision forging technology is relatively weak, the forging quality is not high.
At present, our country except in the car and scale of civil machinery industry begun to take and have the core technology, affected, forging equipment and technical level as weapons, ships, aviation defense equipment manufacturing industry and other countries in need of development is far behind the developed countries, which will undoubtedly have great restriction to enhance China's international status. Because of China's defense industry is in "one five" and "two five" period from initial construction up, coupled with the United States, the socialist countries blocked Western Europe, resulting in our defense industry level behind the developed countries to the two generation level, therefore, need to spare no effort to catch up of China's defense industry, complete air aerospace, navigation, in-depth research on precision forging technology of key parts of special vehicles and weapons and equipment, to ensure national defense capability.
Since the reform and opening up, the rapid development of science and technology change rapidly, material science, computer has been widely used. As the state of the equipment manufacturing industry's attention, the forging of high energy consumption, high pollution industry has also been highly valued, formed by forging new technology, new materials, modern electronic technology, computer technology, precision machining technology. Measurement technology, heating technology, lubrication technology and new equipment and automation technology combined with an advanced precision plastic forming technology. All kinds of new technology, new technology has been applied to forging industry, realize the near net shape or net shape, namely "forming" close to "parts", reached no less the machining level.
