Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of forging processing, in particular to a tool for non-destructive processing of forging cracks. Background Art
[0002] During the process of forging steel ingots into round steel, cracks may appear on the surface of the round steel. If they are not repaired in time, the quality of the round steel will be affected.
[0003] After searching, it was found that the Chinese utility model patent with authorization publication number CN211367732U discloses a device for repairing surface cracks of alloy forgings. It can be seen from its specification that the alloy plate is placed on the workbench, and the cracks of the alloy plate correspond to the laser repair instrument. The first electric telescopic cylinder drives the clamping plate to clamp the alloy plate, so as to ensure the smooth completion of the repair work. The protective mechanism set up can well protect the first electric telescopic cylinder to avoid excessive clamping force due to excessive movement of the first electric telescopic cylinder, thereby extending the service life of the first electric telescopic cylinder. The spray pipe can spray repair solder powder onto the crack. In order to avoid position mismatch, the first soft telescopic tube can be used for alignment to ensure that the powder is accurately sprayed inside the crack. The light outlet emits a laser beam through the concentrator to dissolve the crack and tightly combine the powder and the crack. The auxiliary laser emitting tube can assist in repair.
[0004] The crack repair device in the above patent needs to repair cracks after the alloy forging is completed, and cannot be processed during the forging process, resulting in low efficiency of crack repair processing and also reducing the quality of forgings. Utility Model Content
