In the past, people use traditional ways to clean the dust on the steel. But now, more and more factories choose laser cleaning machine for removing the rust on steel.
Compared with manual cleaning, laser cleaning equipment saves a lot of time and greatly improves the production efficiency. This convenient and efficient cleaning equipment relies on the laser cleaning technology gradually popularized in the domestic high-end manufacturing industry in recent years. This technology solves the problems that have plagued the industry for many years, such as low manual cleaning efficiency, uncertain cleaning quality and difficult to realize automation. It promotes the intelligent upgrading of high-speed rail cleaning in the way of automation integration, saves time, manpower and consumables, and improves the efficiency of high-speed rail manufacturing with scientific and technological innovation.
Since the 18th CPC National Congress, 31000 km of high-speed railway has been put into operation, with double track rate of 59.5% and electrification rate of 72.8%, both ranking first in the world. High speed railway has become a business card representing "created in China" and "made in China". However, it is surprising that in such an advanced manufacturing industry, the cleaning method is still dominated by manual operation, which leads to various disadvantages: manual cleaning is completed by grinding wheel operated by workers, which is difficult to ensure the consistency of effect; The labor intensity of manual cleaning is relatively large, which will increase the labor cost; Manual grinding will also cause noise pollution and dust pollution in the workshop, which will harm the health of operators.
Therefore, with the increasing demand and scale of high-speed rail, the upgrading and transformation of cleaning technology is becoming more and more urgent. In fact, the high-speed rail manufacturing industry has been looking for efficient cleaning methods. Chemical cleaning appears in the field of high-speed rail cleaning as a supplement and substitute for manual cleaning. The so-called chemical cleaning is to wipe the parts to be cleaned with chemical reagents such as acid-base, acetone and alcohol. Although this method promotes efficiency, it also causes pollution. With the increasing attention of the state to environmental protection, chemical cleaning is less and less used in high-speed rail manufacturing. At present, manual cleaning is still the mainstream.
Manual cleaning is inefficient, the effect is difficult to unify, the labor intensity is high, and chemical cleaning has high pollution. Therefore, finding new alternative cleaning methods has become an important task for high-speed rail manufacturing enterprises. Facing the market pain point, laser cleaning, as a new way of industrial cleaning, has begun to emerge in China. It has the advantages of clean cleaning, high efficiency, non-contact and green environmental protection. It can be used to clean not only organic pollutants, but also inorganic substances. Its application scope involves rust removal, oxide film removal, paint removal, oil stain removal, glue removal, coating removal, etc, It is widely used in the field of high-end equipment manufacturing. It has a profound impact on global scientific and technological innovation, industrial structure adjustment and economic and social development.
In the past decade, although laser cleaning has been widely concerned and applied in the high-end manufacturing industry, the high-speed rail industry looking forward to the upgrading of the cleaning method has not noticed this new cleaning method. Until 2016, when engineers of CRRC exchanged welding processes with a laser cleaning enterprise, they put forward the cleaning problem: "There is a layer of black gray oxide on the surface of some parts after welding, which needs to be polished by workers, but some places are very narrow and difficult for workers to operate." the engineer hopes that laser cleaning can help him solve the problem.
Laser cleaning technology has been successfully applied to high-speed railway industry, and the cleaning problem that has plagued high-speed railway manufacturing engineers for many years has finally been preliminarily solved. Moreover, with the vigorous rise of new technologies, new formats and new platforms such as 5g, artificial intelligence and smart city, China is actively promoting the intelligent and digital upgrading of industrial manufacturing. The automatic integration characteristics of cleaning and welding integrated equipment have greatly promoted the intellectualization of cleaning process in high-speed rail production, The whole process intelligent manufacturing upgrade of high-speed rail industry has been further realized.
Although it has achieved phased success, there is still a way to go for the full popularization of laser cleaning in the field of high-speed rail. Promote the innovative development of industries such as integrated circuits, aerospace, ship and marine engineering equipment, robots and advanced rail transit equipment. Laser cleaning is of great significance to enhance the competitiveness of China's high-end manufacturing equipment industry. The laser cleaning industry is developing towards standardization, specialization and high quality, and the prospect of the industry is further clear.
Hope laser cleaning machine can be used in more and more industries. Hope more and more factories use this advanced equipment.
