Problems solved by technology
[0004] In the above technical solution, the wire rod can be placed on the pay-off mechanism for loading and unwinding. However, since the wire rods used for welding wire production are mostly metal wire rods for condensation production, during long-term stacking or transportation, due to the external metal surface The layer is affected by oxidation to form an oxide film, which forms the oxide scale of the epidermis. If it is not treated, the oxide scale on the wire rod diffuses on the metal surface layer, making the oxide scale gradually thicker, which affects the subsequent coating of the electrode coating on the outside of the welding wire

The invention discloses a pretreatment device for feeding a wire rod, comprising a feeding mechanism and a pulling wire frame. A wire winding frame is rotatably arranged on the upper part of the feeding mechanism, and a wire rod edging mechanism is arranged on the upper part of the feeding mechanism. The edging mechanism includes a transmission winding wheel and a flat brush holder; there are two transmission winding wheels, and the two driving winding wheels are arranged in parallel on the upper part of the feeding mechanism, and the lower transmission winding wheel is coaxially and fixedly connected with a reciprocating gear , A single-turn gear is arranged on the lower side of the reciprocating gear, the single-turn gear is rotatably connected with the feeding mechanism, and the upper part of the single-turn gear is meshed with the reciprocating gear. Away from the side of the drawbar. By driving the reciprocating rotation of the coaxially connected transmission reel to pull the wire rod, the invention completes the grinding treatment of the iron oxide scale outside the wire rod under the sliding movement of the translation brush frame, thereby reducing the diffusion of the external iron scale.
Description
technical field [0001] The invention relates to the technical field of welding rod production equipment, in particular to a pretreatment equipment for feeding welding wire rods. Background technique [0002] Welding rod refers to the metal rod that is melted and filled at the joint of the welding workpiece during gas welding or electric welding. The material of the welding rod is usually the same as that of the workpiece. superior. The welding core is the metal core of the electrode. In order to ensure the quality and performance of the weld, there are strict regulations on the content of each metal element in the welding core, especially the content of harmful impurities (such as sulfur, phosphorus, etc.), which should be strictly controlled. The limit is better than that of the base metal. The electrode is composed of two parts: the welding core and the coating. Different types have different solder cores. The composition of the weld core directly affects the compositi...
