Pretreatment equipment for feeding of welding wire rod

Abstract

The invention discloses pretreatment equipment for feeding of a welding wire rod. The pretreatment equipment for feeding of the welding wire rod comprises a feeding mechanism and a wire pulling frame, wherein a wire winding frame is rotationally arranged on the upper portion of the feeding mechanism, and a wire rod edge polishing mechanism is arranged on the upper portion of the feeding mechanism. The wire rod edge polishing mechanism comprises two transmission reels and a horizontal movement brush frame, wherein the two transmission reels are arranged on the upper portion of the feeding mechanism side by side, the transmission reel on the lower side is coaxially and fixedly connected with a reciprocating gear, the lower side of the reciprocating gear is provided with a unidirectional-rotation gear, the unidirectional-rotation gear is rotationally connected with the feeding mechanism, the upper portion of the unidirectional-rotation gear is connected with the reciprocating gear in a meshed mode, and a movable rack is arranged on the side edge of the reciprocating gear and arranged on the side, away from the wire pulling frame, of the feeding mechanism in a sliding mode. According to the pretreatment equipment for feeding of the welding wire rod, the transmission reel coaxially connected with the reciprocating gear is driven to pull the wire rod to rotate in a reciprocating mode, polishing treatment of oxide scales outside the wire rod is completed under sliding of the horizontal movement brush frame, and diffusion of the outer oxide scales is reduced.

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 and coil rods. Background technique [0002] The welding rod refers to the metal strip that is melted and filled at the junction 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, and the coating (coating) is uniformly and centripetally pressed on the welding core outside the metal welding core. superior. The welding core is the metal core of the welding rod. 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 for the content of harmful impurities (such as sulfur, phosphorus, etc.). Limits, superior to base metal. The welding rod is composed of two parts: the welding core and the coating. Different types have...

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
