Key Technologies And Development Prospects Of Roll Forging Machines

1. Heavy industry: Since the reform and opening up, the proportion of heavy industry in the composition of industrial added value in China has been continuously increasing, experiencing a process of "industrial structure heavy industry". Since 2006, the proportion of heavy industry output value in the total industrial output value has reached a new high, rising to over 70%. By 2008, this proportion had even risen to 71.33%. Taking the main application field of roll forging machines in the automotive industry as an example, from the development history of heavy-duty vehicles in various countries around the world, specialized vehicles, diesel locomotives, mining machinery, etc. have shown a trend of heavy-duty and specialized development. Automobile manufacturing companies in various countries have made heavy-duty trucks, high-power engines, and high-tech equipment the development direction of product research and development. The development of heavy-duty vehicles has become a driving force for the rapid growth of the automotive industry and the national economy, directly promoting the upgrading of the industrial structure towards heavy-duty. With the increase in the proportion of heavy industry and the rapid increase in demand for heavy-duty vehicles, the market's demand for large parts has significantly increased. This will lead to insufficient tonnage of existing forging equipment, thus driving the demand for large and heavy forging equipment. Due to the advantages of roll forging machines and their energy-saving characteristics, the demand for large roll forging machines naturally increases significantly. The roll forging machine currently used on the market has achieved 1100mm. It is far from meeting the current needs, so in the coming years, we should accelerate the development of large-scale roll forging machines and put them into the market as soon as possible.
2. Forging: In order to cope with increasingly severe resource and environmental pressures, the forging industry has proposed the sustainable development model of forging. Manufacturing, as a modern manufacturing method that comprehensively considers environmental impact and resource efficiency, aims to minimize the negative impact on the environment and improve resource efficiency throughout the entire product lifecycle from design, manufacturing, packaging, transportation, use to disposal, and to coordinate and optimize the economic and social benefits of enterprises. As a traditional hot working industry, forging has high energy consumption, high pollution, and harsh production environment during the production process. Therefore, it is urgent to adopt this manufacturing model and build a sustainable modern forging enterprise. In order to meet the requirements of social development in forging, the design and use of roll forging machines should follow the path of development, adhering to the concept of high resource utilization efficiency and low environmental impact, and following the principles of energy conservation, environmental protection, and high efficiency.
3. Precision Roll Forging Technology: With the development of China's manufacturing industry, it has gradually shifted from extensive manufacturing with low added value to precision manufacturing with high added value and technological content. Correspondingly, higher requirements have been put forward for the quality of mechanical products. For example, some military products, aerospace products, instrumentation products, automotive products, and micro mechanical products, their accuracy requirements have reached the micrometer level, sub micrometer level, and even nanometer level. This precision requirement determines the development of precision machining and ultra precision machining technology. The development of precision machining technology has also promoted the development of machinery, electronics, optics, hydraulics, sensors, measurement technology, and materials science. At the same time, it has also raised higher requirements for the technical level and machining accuracy of the entire forging industry, including roll forging machines. In addition, the current raw material cost accounts for over 60% of the forging cost composition, and the material utilization rate of roll forging machines in China is around 80%. The potential for improving material utilization rate and reducing metal loss is considerable. To maintain a stable position in the roll forging machine market, it is necessary to improve the quality of roll forging machine products, enhance the performance of precision forming of roll forging, greatly improve the utilization rate of materials, and maintain the competitiveness of roll forging machine production enterprises.
4. Lubrication technology: Existing roll forging machines have many relative moving parts and lubrication points, but lubrication technology is relatively backward. For example, key gear lubrication and sliding bearing lubrication both use open lubrication, which not only wastes lubricating oil, affects aesthetics, pollutes the environment, but also poses hidden dangers due to the high-temperature operation of roller forgings. Therefore, the lubrication technology of the roll forging machine also urgently needs improvement. In addition, some powerful large forging companies abroad have now used robots on a large scale to replace manual production, significantly increasing efficiency and efficiency, while only a few forging companies in China currently use robots. The use of robots will be the trend in the forging profession, which has always been dominated by manual labor and heavily labor-intensive. Within 10 years, China will stride into the era of industrial robots. Therefore, in the design of roll forging process, it is necessary to fully consider the reasonable and efficient connection with robots, so that the roll forging machine can keep up with the era of efficient automation in the forging industry. The equipment manufacturing industry, as a fundamental pillar industry in China, plays an irreplaceable role in the future development of the country's economy. With the deepening of the economy, the total output of forgings in China continues to rise, and forging technology continues to advance. China's forging industry needs to move from a major country to a strong one, complete the forging and low-carbon forging policies, and transform the intelligent and proactive equipment centered on industrial robots. Undoubtedly, this will enhance the competitiveness of forging companies, reflect their manufacturing advantages, and provide stronger support to win market opportunities.
