Description

Technical Field

[0001] This utility model relates to the technical field of metal wire processing equipment, and in particular to a precision tension adjustment wire drawing machine for flux-cored welding wire. Background Technology

[0002] As a key consumable in modern welding processes, the production quality of flux-cored welding wire is crucial to the welding effect. Wire drawing is one of the important processes in flux-cored welding wire production. Applying stable and precise tension to the welding wire during the wire drawing process is key to ensuring uniform diameter and structural integrity.

[0003] However, existing wire drawing machines have shortcomings in tension control. Due to the composite structure of flux-cored welding wire with internal flux powder, it is particularly sensitive to tension fluctuations. Traditional wire drawing machine tension adjustment mechanisms are simple in structure and lack effective buffering mechanisms. When the welding wire is subjected to instantaneous impact during startup or rewinding, rigid or semi-rigid adjustment methods cannot quickly absorb tension fluctuations, resulting in excessive stretching of the welding wire, uneven compaction of internal flux powder, and even wire breakage, which seriously affects the continuity of production and yield.

[0004] Furthermore, even during stable operation, the tension adjustment precision in existing technologies is insufficient to meet the process requirements of high-standard flux-cored welding wires. Existing technologies lack proactive and precise control capabilities, making accurate adjustment difficult. Simultaneously, during high-speed drawing, intense friction occurs between the welding wire and the tension wheel and guide rollers, leading to a sharp increase in local temperature. Existing heat dissipation methods, such as open-air cooling or simple global cooling, are inefficient, with heat concentrated on critical friction components that are difficult to dissipate. This not only exacerbates the wear of components such as rollers and reduces equipment lifespan, but high temperatures also cause degradation of the welding wire surface properties, forcing frequent equipment shutdowns for cooling and reducing overall work efficiency.

[0005] Therefore, this utility model proposes a precision tension-adjustable wire drawing machine for flux-cored welding wire to address the shortcomings of existing technologies. Utility Model Content

[0031] In a preferred embodiment, in order to achieve efficient and safe heat dissipation, a heat dissipation hole 401 is provided on the side wall of the adjustment frame 2.

[0033] As another preferred embodiment, in order to achieve the initial path setting and buffering of the welding wire, the upper and lower ends of the fixing column 301 are fixedly connected in a staggered manner on the rear side of the inner wall of the adjusting frame 2, which is used to guide the welding wire to form an S-shaped path when entering to absorb tension.

[0034] As another preferred embodiment, in order to prevent the welding wire from shifting during the adjustment process, the tapered roller 305 adopts a drum shape with small ends and a large middle. The drum shape is used to automatically center the welding wire on the roller during adjustment.

[0035] As another preferred embodiment, in order to achieve active and precise control of the welding wire tension, the hydraulic pump 306 and the support frame 308 are both arranged in pairs on the upper and lower sides of the inner wall of the adjustment frame 2. The hydraulic pump 306 is used to drive the pair of support frames 308 to adjust the relative distance through the hydraulic rod 307, thereby changing the degree of compression of the welding wire by the upper and lower tension wheels 309.

[0036] Working principle: When the flux-cored wire drawing machine is running with precise tension adjustment, the flux-cored wire enters from the rear side of the adjustment frame 2 and first contacts the fixed post 301, which is fixedly connected in a staggered manner, and the tapered roller 305, which is rotatably connected to the adjustment frame 302. When the tension of the flux-cored wire fluctuates, the flux-cored wire forces the tapered roller 305 and the adjustment frame 302 to slide. The sliding of the adjustment frame 302 compresses the disc spring 304 located between the fixed post 301 and the limit block 303. The disc spring 304 absorbs the impact energy, achieving tension buffering. At the same time, the drum-shaped design of the tapered roller 305 makes the flux-cored wire... As the flux-cored wire moves, it automatically centers itself. After being buffered, the flux-cored wire continues to move forward, passing through the paired tension wheels 309. At this time, the hydraulic pump 306, which is fixedly connected to the front of the adjustment frame 2, starts. The hydraulic pump 306 drives the support frame 308 to move up and down through the hydraulic rod 307, adjusting the distance between the paired tension wheels 309, thereby applying a precise tension value to the flux-cored wire. When the support frame 308 moves, the fixedly connected telescopic rod 310 guides the movement of the support frame 308, preventing the support frame 308 from tilting and ensuring the stability of the adjustment. Furthermore, during the operation of the tension adjustment mechanism 3, the tapered roller 305 and tension wheel 309 generate heat through friction with the flux-cored welding wire. At this time, the cooling fan 402, located in the heat dissipation hole 401, starts and blows cold air into the adjustment frame 2. The protective net 403 protects the cooling fan 402. When it is necessary to adjust the direction of the cooling airflow, the operator swings the adjustment bar 407. The adjustment bar 407 rotates through the connecting frame 406, which is connected by rotation, thereby driving the rotating shaft 404 of the fixedly connected airflow adjustment plate 405 to rotate, thus changing the angle of the airflow adjustment plate 405. This precisely guides the cold air blown out by the cooling fan 402 to the heating position of the tapered roller 305 and tension wheel 309, achieving efficient directional cooling.
