Claims

[Scope of Claim for Utility Model Registration] (1) Welding wire straightening comprising a plurality of rollers arranged alternately along the feeding path from the inlet side to the outlet side of the welding wire, with the wire in between. A welding wire straightening device, characterized in that a wire guide means is provided adjacent to the roller and/or the welding wire feeding path. (2) As wire guide means, recesses capable of accommodating the rollers and having a depth not exceeding the thickness of the rollers are provided at the roller installation positions of the support body that pivotally supports the rollers; A request for registration of a utility model, characterized in that the roller is rotatably housed in the recess, and a wire guide piece for guiding the welding wire is disposed in relation to the roller and the open surface of the support. The welding wire straightening device according to item 1. (3) The welding wire straightening device according to claim 1 or 2, wherein the wire guide piece is fixed to the top surface of a support shaft that rotatably supports the roller. (4) The welding wire straightening device according to claim 1 or 2, wherein the wire guide piece is fixed to an open surface of a support provided to pivotally support the roller. (5) The plurality of rollers are composed of a roller whose support shaft is fixed and a roller whose support shaft is movable in a direction perpendicular to the welding wire feeding path, and at least the fixed side Utility model registration claims 1 to 4, characterized in that a wire guide piece for guiding a welding wire between the roller and the open surface of the support body is disposed in relation to the roller.
2. The welding wire straightening device according to any one of the items. (6) As a wire guide means, a support base for housing the plurality of rollers is configured by removably combining two divided halves, and the roller is rotatably disposed on one of the divided halves. A recessed portion capable of accommodating the roller is provided in the other half of the split body in correspondence with the arrangement position of the roller, and the wire is guided along the welding wire feeding route. The welding wire straightening device according to claim 1, characterized in that a guide groove is provided. (7) One of the divided halves of the support base that accommodates the plurality of rollers is provided with a recess that can accommodate the roller at the roller arrangement position and has a depth that does not exceed the thickness of the roller.
