Weld joint treatment device

Abstract

The invention relates to the technical field of ship manufacturing, and particularly discloses a weld joint treatment device. The weld joint treatment device comprises a device body, a moving assembly, a heating assembly, a cooling assembly, a temperature detector and a controller, wherein the device body is arranged above a weld joint of a ship plate, the moving assembly, the heating assembly, the cooling assembly and the temperature detector are arranged on the side face, close to the ship plate, of the device body, the controller is arranged on the device body, the moving assembly, the heating assembly, the cooling assembly and the temperature detector are all in communication connection with the controller, the moving assembly can drive the device body to move along the weld joint, the heating assembly, the cooling assembly and the temperature detector directly face the weld joint, the heating assembly is used for heating the weld joint, the cooling assembly is used for cooling the weld joint, and the temperature detector is used for collecting the real-time temperature of the weld joint. According to the weld joint treatment device, manual operation is not needed, personal injury to operators is reduced, the temperature and heating time of the weld joint can be accurately controlled, and the stability of the weld joint processed finished product is improved.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a welding seam processing device. Background technique [0002] Shipbuilding is welded by steel plates in the dock. There are tens of thousands of welds in a ship. During the welding process, the uneven expansion of the steel plate will cause welding deformation (caused by residual stress). For the welding deformation that has occurred, mechanical Straightening method or flame straightening method, the mechanical straightening method is to make the ship plate plastically deformed by impact or bending process, and the flame straightening method is to soften the ship plate by heating the ship plate and produce local compression plastic deformation, and shorten after cooling And eliminate welding deformation. [0003] However, the treatment of welding deformation is mainly manual operation. When using the flame straightening method, personal safety accidents are likely to occu...

Problems solved by technology

[0003]However, the treatment of welding deformation is mainly manual operation. When using the flame straightening method, personal safety accidents are likely to occur in the high temperature environment, and harmful gases will be produced during the heating process to pollute the The human respiratory tract; when using the mechanical correction method, the impact on the ship plate will easily lead to the emission of rust dust, which will cause great damage to the respiratory tract of the workers, and it is easy to get pneumoconiosis when working in this environment for a long time

Moreover, whether it is mechanical straightening method or flame straightening method, manual processing requires high manual operation, which makes the finished welded seam treatment unstable.
