Abstract

The present invention provides a welding wire feeding device (1) which can simplify change operation of a welding wire passage component that is equipped between a feeding reel (10) and pipeline (2) and feeds the welding wire (3) to the pipeline (2), namely a welding wire guide rail (50). For this purpose, a slot part (50a) is equipped at an outer peripheral surface at an end of the feeding reel (10) of the welding wire guide rail (50). Because a fixing component (60) which inserts a stopping part (60c) that elastically reduces diameter in a diameter direction of the welding wire guide rail (50) into the slot part (50a) for fixing the welding wire guide rail is provided, fixing of a slot part (50b) is released through pressing down an end face at the side of the feeding reel (10) of the welding wire guide rail (50) in the welding wire feeding direction oppositely to the elastic force of the fixing component (60) when the welding wire guide rail (50) is replaced, thereby releasing fixing of the slot part (50b). Therefore the welding wire guide rail (50) can be detached.

Description

technical field [0001] This invention relates to improvements in welding wire feeders. Background technique [0002] In molten electrode arc welding, a wire feeding device is used in order to feed the welding wire stably. (For example, refer to Patent Document 1.) In the prior art, as this welding wire feeding device, Figure 4 The device shown is widely used. Figure 4 It is a partial sectional view showing the structure of a conventional welding wire feeding device. In this figure, a wire feeder 1 is equipped with a feed motor (not shown), and a feed reel 10 is attached to a motor shaft of the feed motor by a feed reel attachment screw 11 . [0003] A pressure roll 12 is disposed opposite to the feed roll 10 . The pressure reel 12 is attached substantially at the center of the pressure reel holding member 13 , and the base end portion of the pressure reel holding member 13 is rotatably attached to the wire feeder main body. The pressurizing force adjusting mechanism 14 ...
