Description
Technical Field
The invention relates to a metal cutting method, in particular to a bridge steel plate cutting method capable of completely removing slag, and belongs to the technical field of steel plate cutting and cutting methods.
Background
Generally, metal cutting refers to a process of preheating metal to be cut to an ignition point capable of burning or softening by using natural gas flame (oxy-natural gas), and then releasing high-pressure oxygen flow to further violently oxidize the metal and blow away slag generated by burning to form a cut.
Metal cutting is a very important metal processing and treating means, and is currently applied to a very large number of technical fields, and is a very important, well-known and widely applied technical means.
Among metal cutting, steel plate cutting is a very important type (because steel is most widely and commonly used), which is widely used in, for example, ship manufacturing, bridge processing, automobile industry, machining, etc., and is the most common type of steel plate treatment in the industry.
In the steel plate cutting process, a steel plate to be cut needs to be placed on a stand. In this rack, the base plate on which the steel plates are placed is generally grid-shaped, and the gap during cutting is located in the gap between the two grid plates (so that cutting to the base plate is avoided). However, the existing grid plate has some defects, such as: 1. the grid plate is usually fixed and cannot move, so that the gap between the two grid plates is not adjustable when the grid plate is used; 2. the steel plate is generally not moved in consideration of the dead weight of the steel plate, so the steel plate needs to be positioned before processing, and the steel plate cannot be moved randomly after the processing is started; if the steel plate is moved according to different cutting seam length and width to meet the cutting requirement, the moving of the steel plate easily causes the cutting position to move, the cutting quality is influenced, the rejection rate is increased, the labor is occupied, and the cutting efficiency is reduced; 3. the steel plate placing device is generally not provided with a corresponding positioning device, so that the situation that the steel plate is not placed in place once and needs to be adjusted for many times is caused, the processing efficiency is also seriously influenced, the production rate is reduced, and the like.
Therefore, there is a need for continued research on a steel plate cutting apparatus including a steel plate bracket. On the other hand, in the current society where traffic is rapidly developed, the efficiency of bridge construction needs to be greatly improved. In the process of bridge construction, the steel plate needs to be cut into various shapes according to different requirements and needs to be welded again. However, the traditional steel plate cutting machine needs to be beveled and slag-removing welded after cutting, which wastes a large amount of manpower and material resources, is low in efficiency, and cannot meet the requirements of fast-paced development and bridge construction of the current society.
Moreover, after the conventional steel plate cutting machine discharges the material, the cutting slag on the cutting edge of the cut plate needs to be manually removed. However, the working procedure not only increases the labor intensity of operators, but also occupies a lot of working hours, reduces the processing efficiency and the production efficiency, increases the operating cost and time, and indirectly influences the progress of bridge construction.
Therefore, based on the above drawbacks, in the field of steel plate cutting technology, especially in the field of bridge steel plate cutting technology, there is still a need for research and improvement on a novel deslagging method for cutting bridge steel plates, which is also a research focus and focus in the field at present, and is the starting point and power of the present invention.
