Abstract

The invention relates to a device for releasing the reinforcing plate welding internal stress. The device comprises a conveying roller path which is arranged on a bracket and back burning flame mechanisms which are matched with the conveying roller path; a shunting row which is connected with each back burning flame mechanism is arranged below the conveying roller path; one end of the conveying roller path is provided with a gas source tank and a pressure regulating valve; a positioning sensor is arranged above the conveying roller path; and each back burning flame mechanism comprises a plurality groups of roasting flares, a transmission mechanism used for moving the roasting flares and dragging chains which are matched with the roasting flares respectively. By adopting the device, a coordinate of a reinforcing plate needing back burning is determined through the positioning sensor, and then operation of each back burning flame mechanism is regulated, so that the purpose of simultaneously, rapidly and effectively finishing back burning is achieved by controlling operation of the back burning flame mechanisms, the trouble and the labor are saved, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a device for releasing the internal stress of rib plate welding and a method for using the same, in particular to a device for automatically releasing the internal stress of rib plate welding during the vertical production of ship groups. Background technique [0002] In the shipbuilding process, the production of small stand-up workpieces requires the application of welding processes. In order to improve or eliminate various structural defects and residual stresses caused by the welding process of steel and prevent deformation and cracking of the workpiece, it is necessary to perform annealing heat treatment on the small and vertical workpieces after welding to release the welding internal stress. [0003] Moreover, the group stand production is located at the front end of the ship construction cycle, and its processing quality directly affects the subsequent assembly, segmen...
