Abstract

Technical Field
[0001] This utility model relates to the technical field of welding wire processing equipment, specifically a softening device for welding wire processing. Background Technology
[0002] Welding wire is a type of metal wire used as filler metal or simultaneously as a conductor in welding processes. It consists of metal wires of a certain length and diameter. Currently, there are many types of welding wire available on the market, suitable for various welding applications. During the production process, welding wire undergoes softening annealing to relieve stress and maintain excellent mechanical properties during subsequent drawing and other production processes. This reduces the likelihood of wire breakage and ensures that the wire meets the requirements for welding applications.
[0003] Traditional welding wire annealing equipment uses an oven. After the welding wire is placed in the oven, the temperature is adjusted to a preset annealing temperature for annealing. The heating device inside the oven is fixed, resulting in uneven heating of the metal welding wire in different locations. This method leads to low annealing efficiency and uneven annealing quality. Therefore, we propose a softening device for welding wire processing. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figures 1-5 A softening device for welding wire processing includes a softening furnace 1, which heats and holds the welding wire at a specific temperature to eliminate cold work hardening, reduce strength and hardness, and improve plasticity through heat treatment, thereby meeting the requirements of drawing or welding processes. A sealing door 2 is fixedly installed on the softening furnace 1 for sealing and opening.
[0028] Multiple heating rods 4 are fixedly installed at the top of the softening furnace 1. These heating rods 4 are arranged in a circular array to provide a hot atmosphere inside the softening furnace 1, heat-treating and softening the welding wire to eliminate cold work hardening. A partition 3 is fixedly installed near the bottom of the softening furnace 1. Limiting posts 5 are installed on the partition 3 via a rotating mechanism 6. The limiting posts 5 are used to limit the welding wire, thereby facilitating uniform heating of the welding wire.
[0029] The rotating mechanism 6 can drive the limiting post 5 to rotate while simultaneously causing the limiting post 5 to rotate on its own axis, thereby ensuring uniform heating of the welding wire. The limiting post 5 includes a threaded groove 51 formed on its surface for winding the welding wire, ensuring that the welding wire is wound within the threaded groove 51 and does not pile up, thus preventing uneven heating. Multiple positioning rods 52 are mounted on the surface of the limiting post 5, preferably four in a circular array, which can limit the welding wire, preventing it from detaching from the limiting post 5 and ensuring that the welding wire is not too tightly pressed against the limiting post 5, thus preventing uneven heating.
[0030] Please see Figures 2-3The rotating mechanism 6 includes a turntable 61, which is rotatably mounted on the upper end of the partition 3. A limit post 5 is detachably mounted on the turntable 61. A rotating motor 64 is fixedly connected to the bottom end of the turntable 61. The rotating motor 64 can drive the turntable 61 to rotate, thereby causing the limit post 5 to rotate synchronously with the turntable 61, so that the welding wire on the limit post 5 is heated more evenly.
[0031] Multiple gears 62 are rotatably mounted on the bottom of the turntable 61, and the gears 62 are detachably connected to the limiting post 5, including snap-fit connections and threaded connections. This connection between the gears 62 and the limiting post 5 allows the rotation of the gears 62 to drive the limiting post 5 to rotate synchronously. A geared disc 63 is fixedly mounted on the top of the partition 3, meshing with the gears 62. The geared disc 63 is located inside the turntable 61. When the turntable 61 rotates, it drives the gears 62 to rotate synchronously. Because the gears 62 and the geared disc 63 are meshed and the geared disc 63 is fixedly mounted on the partition 3, the gears 62 rotate along the geared disc 63. The rotation of the gears 62 drives the limiting post 5 to rotate synchronously, so that the limiting post 5 can rotate synchronously with the turntable 61 while also rotating on its own axis, resulting in more uniform and stable heating of the welding wire.
[0032] Please see Figures 4-5 A sample loading mechanism 7 is provided between the limiting post 5 and the softening furnace 1 to quickly load the welding wire onto the limiting post 5, facilitating the loading of the welding wire. The sample loading mechanism 7 includes a sliding seat 71, which is fixedly installed at the top of the softening furnace 1 and communicates with the softening furnace 1. A fixing plate 72 is fixedly installed inside the sliding seat 71, and a cylinder 73 is fixedly installed on the fixing plate 72. The output shaft of the cylinder 73 passes through the fixing plate 72 and is fixedly connected to a feeding box 74. The position of the feeding box 74 can be adjusted by the operation of the cylinder 73.
[0033] Multiple rotating columns 75 are rotatably installed inside the feeding box 74. The multiple rotating columns 75 are in contact with each other and have multiple notches. The rotating columns 75 are adapted to the positioning rod 52. The positioning rod 52 can be engaged into the notch of the rotating column 75, so that the rotating column 75 and the positioning rod 52 form a surrounding of the surface of the limiting column 5.
[0034] A feed inlet 76 is fixedly connected to the top of the feeding box 74 for feeding welding wire. A feed roller 78 is fixedly installed on one side of the softening furnace 1. The feed roller 78 has two rotating rollers with an arc-shaped groove between them for conveying the welding wire. A motor is fixedly connected to the rotating rollers. The rotation of the motor drives the rotating rollers to rotate, thereby conveying the welding wire through the friction between the welding wire and the rotating rollers. A notch is opened on the softening furnace 1 near the feed roller 78, and the notch is aligned with the feed inlet 76, so that the welding wire can be conveyed into the limiting post 5 by the feed roller 78.
[0035] A sealing frame 77 is fixedly installed on the bottom of the surface of the feeding box 74. The sealing frame 77 is in contact with the inner wall of the softening furnace 1. When the feeding box 74 moves upward, the sealing frame 77 will seal with the opening on the softening furnace 1, thereby ensuring that the softening furnace 1 is in a sealed state when the temperature is raised.
[0036] It should be noted that both the partition 3 and the fixed plate 72 are sealed and heat-insulated structures, which minimizes the impact on the rotating motor 64 and the cylinder 73 when the softening furnace 1 is heated.
[0037] A softening device for welding wire processing, the working principle of which is as follows:
[0038] Cylinder 73 is activated, causing the feeding box 74 to shift, locking it and the rotating column 75 onto the limiting column 5. Then, the feeding roller 78 is activated, feeding the welding wire through the feed port 76 into the limiting column 5. Because of the rotatable connection between the rotating column 75 and the feeding box 74, the welding wire rotates more stably through the threaded groove 51, preventing jamming. Once the welding wire is completely coiled inside the threaded groove 51 of the limiting column 5, cylinder 73 is activated, disengaging the feeding box 74 from the limiting column 5. The feeding of a single limiting column 5 is complete. The rotating motor 64 is activated, causing the turntable 61 to rotate, which in turn moves the limiting column 5 synchronously until it is at the bottom of the feeding box 74. The feeding of the welding wire is completed by activating cylinder 73 and the feeding roller 78.
[0039] After the welding wire is fed, the rotary motor 64 and heating rod 4 are started. The heating rod 4 heats the softening furnace 1 to provide a hot atmosphere for softening the welding wire. When the rotary motor 64 rotates, it drives the limiting post 5 to rotate synchronously. At the same time, when the turntable 61 rotates, it drives the gear 62 to rotate synchronously. Since the gear 62 and the gear disk 63 are meshed and the gear disk 63 is fixedly installed on the partition plate 3, the gear 62 rotates along the gear disk 63. The rotation of the gear 62 drives the limiting post 5 to rotate synchronously. Thus, the limiting post 5 can rotate synchronously with the turntable 61 and also rotate on its own axis, resulting in more uniform and stable heating of the welding wire.
[0040] Once softening is complete, the limiting post 5 can be removed from the turntable 61 by opening the sealing door 2, making it easier to remove the welding wire from the limiting post 5. Furthermore, the next welding wire softening can be achieved more quickly by installing a blank limiting post 5, thereby improving work efficiency.
