Description

Flame cutting device Technical Field The utility model belongs to the technical field of flame cutting, and particularly relates to a flame cutting device. Background With the continuous progress of technology and the continuous growth of demands for efficient and high-performance equipment in the market, the trend of equipment upsizing is more remarkable. The large-scale equipment not only can greatly improve the production efficiency, but also can bear more complicated and difficult tasks in various fields. At the same time, the "cast in steel" strategy is widely practiced in the industry. Compared with castings, the steel has the advantages of better mechanical property, higher strength-weight ratio, stronger quality stability and the like, so that the requirements of large thick plates in the field of equipment manufacturing are rapidly increased. The thick plate plays an indispensable role in the production of key parts of various large equipment. In the field of heavy machinery, key structural members such as a main frame of a large crane and mining equipment are manufactured by relying on a large thick plate. The main frame constructed by the large thick plates needs to bear huge load and complex stress, and the stable operation of the machine under severe working conditions is ensured. In petrochemical industry, the manufacturing of pressure vessels such as reaction towers and storage tanks is not separated from the manufacture of large thick plates. The pressure containers are required to be in service for a long time in the environment of high temperature, high pressure and strong corrosive medium, and the high-quality performance of the large thick plate ensures the safety and reliability of the containers. In the aspect of large-scale bridge construction, a large number of important structural components such as main beams, bridge towers and the like of the bridge use large thick plates. The large thick plate endows the bridge with excellent bearing capacity and wind resistance and earthquake resistance, and ensures the stability of the bridge in the long-term use process. Flame cutting is used as a primary procedure in the production and processing flow of structural parts, and plays a significant role in the whole manufacturing link. In flame cutting of large thickness sheet materials, a large amount of heat needs to be released in order to melt the cut area of the sheet material. This process generates extremely high temperatures, which cause the temperature of the space above the cut sheet to rise rapidly. The cutting torch lifting mechanism and the guiding components in all directions above the plate are extremely easy to be influenced by the high-temperature environment, a large amount of generated heat can be continuously radiated to the cutting torch lifting mechanism and the guiding components in all directions, deformation can be easily caused by long-time heating, the cutting precision of the flame cutting device can be greatly reduced, even a clamping fault can occur, and the flame cutting device cannot normally operate. The service life of the flame cutting device is greatly shortened, and the maintenance cost of equipment is obviously increased. Disclosure of utility model The utility model provides a flame cutting device, which aims to solve the problems that when a traditional flame cutting device cuts a large thick plate, a cutting torch lifting mechanism and guide parts in all directions are extremely easily and obviously influenced by a high-temperature environment, so that the cutting precision is greatly reduced and even a clamping fault occurs.
