Description

Technical Field

[0001] This utility model relates to the field of welding wire production technology, specifically to a wire drawing machine for drawing welding wire to prevent breakage. Background Technology

[0002] During the manufacturing process of flux-cored welding wire, a drawing stage is involved. A higher wire compression ratio during drawing requires a greater drawing force, leading to more pronounced work hardening and a higher probability of wire breakage, thus affecting normal production. To reduce breakage, the traditional approach is to appropriately control the wire compression ratio in each drawing pass to minimize work hardening. However, reducing the compression ratio increases the number of drawing passes, impacting production efficiency. Alternatively, work hardening can be eliminated through hot working annealing. Traditional annealing processes mostly use vacuum annealing furnaces or heat pipe annealing furnaces, but these two types of equipment are energy-intensive. The product quality is unstable, and the equipment and wire drawing machine are independent of each other, so they cannot output annealed welding wire in one go. Among them, the anti-breakage wire drawing machine for drawing welding wire with application number "CN202020531904.8" uses an energized induction coil after the fine drawing module to anneal the welding wire to eliminate the work hardening of the welding wire. However, this wire drawing machine still has some shortcomings in use: after annealing and cooling, there will be oxide stains on the surface of the welding wire. Since it is impossible to remove stains and lubricate the surface of the welding wire, the welding wire is prone to rust after being directly wound, which affects subsequent use. Utility Model Content

[0003] The purpose of this invention is to provide a wire drawing machine for preventing breakage of welding wire, in order to solve the problem mentioned in the background art that there are oxide stains remaining on the surface of the welding wire after annealing and cooling, and that the welding wire is prone to corrosion after direct winding because it is impossible to remove stains and lubricate the surface of the welding wire, which affects subsequent use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a wire drawing machine for preventing breakage when drawing welding wire, comprising a mounting frame, a polishing assembly, and an oil injection assembly;

[0005] Wherein: a unwinding frame is mounted on the surface of the mounting frame, and an unwinding motor that is drively connected to the unwinding frame is mounted on the surface of the mounting frame;

A drive motor is fixedly mounted on the back of the support plate. A drive gear is fixedly mounted on the output end of the drive motor. Two transmission rods are rotatably mounted on the surface of the support plate. Polishing wheels are mounted on the surface of both transmission rods. The welding wire is inserted through the middle of the two polishing wheels. A driven gear is fixedly mounted on one end of one of the transmission rods. The drive gear and the driven gear are meshed and connected.

[0007] The oil injection assembly includes a mounting base installed on the top of a support frame. A servo cylinder is fixedly mounted on the top of the mounting base.

The drive motor is fixedly installed on the back of the support plate. The drive motor rotates and drives the meshing driven gear to rotate together through the active gear, thereby driving the two transmission rods to rotate.

[0015] (2) The piston plate moves inside the oil tank by extending the control servo cylinder at the top of the mounting base. The piston plate pushes the internal grease to be delivered into the oil pipe. The solenoid valve is used to control the opening and closing of the oil pipe. The grease is sprayed onto the polishing wheel through the nozzle at the bottom of the oil pipe, so that the polishing wheel lubricates the surface of the welding wire during the polishing process, playing a protective role and facilitating the excellent lubrication performance of wire feeding during subsequent processing.
