Description
Technical Field
[0001] This utility model relates to the technical field of welding wire production, and in particular to a rust-proofing and oiling device for finished welding wire products. Background Technology
[0002] Welding wire is a metal wire used in welding, either as filler metal or as a conductor. In gas welding and tungsten inert gas (TIG) welding, welding wire is used as filler metal.
[0003] Existing rust-preventing and oiling devices for finished welding wires, such as the rust-preventing and oiling device for welding wire disclosed in utility model patent application number 202321502079.9, mainly include a lubrication box. The welding wire body is horizontally slidably inserted through the center of the lubrication box. A middle plate is vertically provided in the middle of the inside of the lubrication box. Both ends of the welding wire body slide through the middle plate. The lubrication box is symmetrically provided with mounting brackets on the side near the end of the welding wire body. In use, one end of the welding wire body is passed through the center of the lubrication box and the oiling sponge, and the end of the welding wire body is connected to the reel. Then, the motor is started. The motor drives the output shaft to rotate with the cooperation of the mounting plate. The motor output shaft drives the rotating shaft to rotate. When the rotating shaft rotates, it drives the reel to rotate with the cooperation of the mounting brackets.
[0004] However, most existing oiling devices rely on a single nozzle to spray oil and then a sponge to spread the rust-preventive oil evenly. This can easily lead to uneven oil film thickness, with thicker oil films on the sprayed areas. In addition, the sprayed oil mist evaporates and drips a lot, resulting in low utilization of the rust-preventive oil and increased production costs. Utility Model Content
