[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] like Figures 1-3As shown, this utility model discloses a smelting device for producing tungsten steel bars, comprising a horizontally arranged rectangular frame 1 and a smelting cylinder 2 vertically arranged inside the rectangular frame 1. A stirring assembly 3 is installed inside the smelting cylinder 2 to stir the materials. The upper end of the smelting cylinder 2 is hinged to the middle of the front and rear ends of the rectangular frame 1 via a pair of longitudinally hinged rotating shafts 4 distributed front and rear. The smelting cylinder 2 is driven by a swinging assembly 5 to swing left and right around the pair of longitudinally hinged rotating shafts 4. During operation, materials enter the smelting cylinder, the stirring assembly inside the smelting cylinder stirs the materials, and the swinging assembly drives the smelting cylinder to swing left and right around the pair of longitudinally hinged rotating shafts, achieving left-right swaying. The combination of these two actions effectively improves the stirring and mixing effect of the materials inside the smelting cylinder, thereby effectively improving the uniformity and efficiency of material smelting.

[0020] In this embodiment, the oscillating assembly 5 includes an arc-shaped rack 6, a drive gear 7, and an oscillating drive motor 8. The arc-shaped rack 6 is installed in the middle of the outer bottom surface of the melting cylinder 2, and its axis extends longitudinally. The drive gear 7 is located directly below the arc-shaped rack 6, and its axis extends longitudinally, meshing with the arc-shaped rack 6. The oscillating drive motor 8 is located in front of the drive gear 7, and its output shaft is connected to the central shaft of the drive gear 7, causing the drive gear 7 to rotate. During operation, the oscillating drive motor drives the drive gear to rotate, which in turn drives the arc-shaped rack to rotate. Because the arc-shaped rack is fixedly connected to the melting cylinder, it causes the melting cylinder to oscillate left and right around a pair of longitudinally hinged shafts.

[0021] In this embodiment, the swing assembly 5 further includes a U-shaped swing base 9 located directly below the melting cylinder 1, the drive gear 7 is installed inside the swing base 9, and the swing drive motor 8 is installed on the outside of the swing base 9.

[0022] In this embodiment, the lower part of the melting cylinder 1 is arc-shaped to facilitate the welding and installation of the arc-shaped rack.

[0023] In this embodiment, a horizontal base plate 10 is provided at the lower end of the interior of the melting cylinder 1. The horizontal base plate is located below the stirring assembly. A discharge pipe 11 is connected to the lower end of the right side wall of the melting cylinder 1. The discharge pipe 11 is connected to the horizontal base plate 10 to facilitate the output of the smelted material. Preferably, in order to accommodate the left and right rotation of the melting cylinder, the discharge pipe is a flexible hose.

[0024] In this embodiment, the stirring assembly 5 includes a stirring shaft 12 vertically disposed in the middle of the melting cylinder 1. The stirring shaft 12 is driven to rotate by a stirring motor 13 installed at the top of the melting cylinder 1. Multiple stirring rods 14 are disposed on the outer surface of the stirring shaft 12, and the stirring rods are inclined downward. During operation, the stirring motor drives the stirring rods to rotate through the stirring shaft, thereby stirring the material inside the melting cylinder.

[0025] In this embodiment, a feed pipe 15 is connected to the top of the melting cylinder 1, and the feed pipe 15 is connected to the material preheating assembly 16. Preferably, the feed pipe is a flexible hose to accommodate the left and right rotation of the melting cylinder. Since different materials require different heating and melting times, the melting process is often time-consuming and the melting effect is poor. To solve this problem, this embodiment uses a preheating assembly to preheat the material before it enters the melting cylinder. The preheated material then enters the melting cylinder for melting. Because the material is preheated to a certain temperature, the melting time in the melting cylinder is reduced, and the melting effect is more complete.

[0026] In this embodiment, the material preheating assembly 16 includes two preheating chambers 17 arranged side by side. Each preheating chamber 17 has a preheating stirring assembly 18 inside. Heating elements are arranged on the periphery of each preheating chamber 17, and a material output pipe 19 is connected to the bottom of each preheating chamber 17. The material output pipe 19 is connected to the feed pipe 15. Furthermore, each material output pipe at the bottom of the preheating chamber is equipped with a control valve. Furthermore, the structure of the preheating stirring assembly inside the preheating chamber is the same as the structure of the stirring assembly inside the melting cylinder.

[0027] In this embodiment, vertical support rods 20 are fixed at the four top corners of the bottom of the rectangular frame 1, and the vertical support rods 20 support the rectangular frame 1 and the melting cylinder 2 at a certain height above the ground.

[0028] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then, unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws), or a non-detachable fixed connection (e.g., riveting, welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured using a casting process) (except where it is obviously impossible to use an integral forming process).

[0029] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in this utility model above include states or shapes that are similar to, close to, or approximate with them.

[0030] Any component provided by this utility model can be assembled from multiple individual components, or it can be a single component manufactured by a one-piece molding process.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
