Description

Technical Field

[0001] The utility model relates to the technical field of remanufacturing and repairing, and more specifically, to a steel electric arc additive remanufacturing and repairing device. Background Art

[0002] Additive remanufacturing repair uses arc additive manufacturing technology to add material to damaged molds without replacing the entire component, and perform arc welding repairs on local damage to extend its service life. This technology is mainly used to repair damaged or worn steel parts to restore their original size and function.

[0003] Most of the current arc surfacing is done manually, which is inefficient and lacks fixation of the mold, which can easily cause damage and affect the repair efficiency. In addition, the general fixing device cannot change according to the external shape of the mold, making the fixation not firm enough.

[0004] After searching, a Chinese patent with publication number CN209754238U discloses a fixing device for arc additive remanufacturing of molds. The mold is placed above a movable plate, clamped by a movable plate, and driven by a spiral motor to push a pressure plate to extrude granular fillers. The fillers are used to extrude a deformable shaping plate, so that the shaping plate contacts the mold and due to the existence of the extrusion force, the shaping plate changes shape according to the external shape structure of the mold, thereby achieving full contact with the mold, and then clamping and fixing the mold. This fixation is more stable and will not cause displacement of the mold during arc surfacing. At the same time, the movable plate can move and adjust its position according to arc surfacing, so that the remanufacturing process is more efficient and of better quality.

[0005] However, in actual use, during the repair process, the spiral motor works to push the pressure plate to drive the shaping plate to contact the mold, so that the shaping plate and the mold are in full contact. During arc surfacing, the position of the mold needs to be constantly adjusted to ensure the repair accuracy. This requires the structure to frequently open the mold and the shaping plate and then fix them, which makes the operation complicated and affects work efficiency. Utility Model Content
