The invention relates to the field of ship welding and manufacturing, and in particular to an intelligent electromagnetic induction backburning device for ship manufacturing and a working method thereof.

Background technique

During ship construction, a large number of steel structures use medium-thick steel plates of 12mm or more. These steel plates have large stresses after welding. In order to ensure the safety and service life of the ship during operation, these stresses must be eliminated. At present, most shipyards use pyrotechnics to eliminate these stresses. However, pyrotechnics relies heavily on workers' experience, and the process of pyrotechnics will produce a large amount of toxic gases that can harm workers' bodies. In addition, the production efficiency of pyrotechnics is relatively low. Low, labor intensity is high.

At present, electromagnetic induction heating is widely used in preheating before welding, steel plate production, quenching, thin plate correction and other fields. Most back-burning equipment uses gas combustion heating and pyrotechnics to work. There are few intelligent electromagnetic induction back-burning equipment. For example, patent CN201811271207.7 protects an online automatic back-burning device for small vertical robots, which can only back-burn small vertical parts and uses gas heating. CN201620779622.3 protects a back-burning car that relies on human power and still relies on gas heating. CN201821785335.9 protects the weld back burning system of large-scale public buildings. It relies on rail advancement. The system is relatively complex and uses gas for heating. CN201820057622.1 protects a back-burning trolley, which is also driven by manpower and heated by gas. Patents CN201210399255.0, CN201720696318.7, and CN201410280212.X protect technical solutions that use air sources for heating.
