Technical Field
[0001] This utility model relates to the field of wheel rim production and processing technology, and in particular to a wheel rim material smelting furnace. Background Technology
[0002] As a key load-bearing component of vehicles such as automobiles and motorcycles, wheel rims require the initial melting of raw metal materials such as aluminum alloys and steel to form a molten metal with uniform composition and acceptable impurity levels. This molten metal is then further processed through casting, forging, and other techniques to create the initial wheel rim shape. The quality of the rim material melting process directly determines the mechanical properties (such as strength and toughness) and service life of the wheel rim. Therefore, the stability, uniformity of mixing, and ease of cleaning of the melting equipment are crucial to the production efficiency and quality of the finished wheel rim. During the smelting process of wheel rim materials, a smelting furnace is required to heat and melt the metal raw materials at high temperatures, and a stirring mechanism is used to ensure that the composition of the molten metal is uniform, so as to avoid defects such as cracks and bubbles in the finished wheel rim due to local composition deviations. When existing stirring blades come into contact with molten metal at high temperatures, a hard layer of metal residue forms on their surface. Since the stirring blades are not easy to disassemble individually, the entire stirring rod must be separated from the motor during cleaning, which is a complex process. Repeated disassembly can also reduce the connection accuracy between the motor output shaft and the stirring rod, affecting the stability of subsequent stirring. The metal residue remaining in the furnace cavity needs to be scraped off manually with tools, which is not only time-consuming and laborious, but may also scratch the inner wall of the furnace cavity due to human error, shortening the service life of the smelting furnace. After the smelting furnace cools down, there is still some residual heat, and manual entry into the furnace for cleaning can easily cause burns. In addition, the metal dust generated during the cleaning process may also affect the health of the operators. Therefore, a rim material smelting furnace is proposed. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as the formation of a hard metal residue layer on the surface of the stirring blades after contact with molten metal at high temperatures; the difficulty in disassembling the stirring blades individually, requiring the entire stirring rod to be separated from the motor for cleaning, resulting in a complex disassembly process; repeated disassembly leading to a decrease in the connection accuracy between the motor output shaft and the stirring rod, affecting the stability of subsequent stirring; the need for manual scraping of residual metal residue in the furnace cavity, which is not only time-consuming and labor-intensive but also prone to scratching the inner wall of the furnace cavity due to human error, shortening the service life of the smelting furnace; the residual heat remaining in the smelting furnace after cooling, which poses a risk of burns when manual cleaning is performed; and the metal dust generated during the cleaning process potentially affecting the health of operators. Therefore, this invention proposes a rim material smelting furnace.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: A wheel rim material smelting furnace includes a smelting furnace with a mounting frame assembly. A stirring mechanism is mounted above the smelting furnace via the mounting frame assembly. The stirring mechanism includes a drive component, a cleaning component, and multiple stirring elements. The drive component includes a motor and a stirring rod. The stirring rod is detachably fixed to the output end of the motor.

[0010] In one embodiment, a plurality of limiting strips are fixedly connected to the outer side of the stirring rod, and a limiting groove adapted to the limiting strips is opened on the inner wall of the fixing ring, and the limiting groove and the limiting strips are slidably connected.
[0011] Using the above method, the sliding fit between the limiting strip and the limiting groove provides guidance for the installation of the fixing ring, ensuring that the adjusting hole and the fixing hole are precisely aligned and reducing installation errors. On the other hand, it can prevent the fixing ring from rotating due to the resistance of the molten metal during stirring, ensuring that the stirring blade always works at the preset angle, thereby improving the stirring stability and uniformity.
[0012] As one implementation, a second fixing bolt is connected through the U-shaped cleaning frame, the second fixing bolt is connected through to the fixing hole, and the end of the second fixing bolt is threaded with a second fixing nut.

[0015] Using the above method, the cleaning strip can be removed individually by replacing the bolts. When the cleaning strip is worn or aged, there is no need to replace the U-shaped cleaning frame, reducing maintenance costs. At the same time, different types of cleaning strips, such as cleaning brushes and steel brushes, can be replaced according to the material of the furnace cavity to avoid scratching the inner wall of the furnace cavity and extend the service life of the furnace.

[0023] like Figures 1-6As shown, this utility model proposes a rim material smelting furnace, including a smelting furnace 7. A mounting frame assembly is provided on the smelting furnace 7, and a stirring mechanism is mounted on top of the smelting furnace 7 via the mounting frame assembly. The stirring mechanism includes a driving component, a cleaning component, and multiple stirring elements. The driving component includes a motor 4 and a stirring rod 6. The stirring rod 6 is detachably fixed to the output end of the motor 4. Each stirring element includes a fixing ring 9 mounted on the outside of the stirring rod 6 via a quick-release assembly. Two stirring blades 10 are symmetrically arranged on the outside of the fixing ring 9. The stirring blades 10 are located inside the smelting furnace 7. The cleaning component includes a U-shaped cleaning element. The cleaning frame 16 is detachably fixed to the outside of the stirring rod 6. The cleaning frame 16 is located inside the smelting furnace 7. A cleaning strip 17 is provided on the outside of the cleaning frame 16. The stirring mechanism can be adapted to different specifications of smelting furnace 7 and different rim materials by the detachable drive component and quick-release adjustment of the stirring component, thereby improving the uniformity of stirring. The cleaning component is integrated with the stirring mechanism to realize mechanical cleaning instead of manual cleaning, thereby improving cleaning efficiency and safety. The stirring rod 6, stirring blade 10 and cleaning component are all designed to be detachable, which reduces the difficulty of maintenance and operation and reduces equipment downtime.
[0024] An output rod 5 is fixedly connected to the end of the output shaft of motor 4. The output rod 5 is in contact with the stirring rod 6. A connecting block 11 is fixedly connected to the end of the stirring rod 6. A slot for the connecting block 11 is provided at the end of the output rod 5. The connecting block 11 is inserted into the slot. A connecting bolt 12 is threaded onto the output rod 5. The connecting bolt 12 is connected through the connecting block 11. The cooperation between the connecting block 11 and the slot ensures that the stirring rod 6 and the output rod 5 are coaxial, preventing shaking during stirring. The connecting bolt 12 can quickly lock or unlock both. The stirring rod 6 can be disassembled without professional tools, which is convenient for cleaning and avoids equipment damage caused by repeated disassembly of motor 4, improving disassembly and assembly efficiency and equipment stability.
[0025] The agitator includes multiple fixing holes 8 on the outside of the agitator rod 6, and multiple adjusting holes 14 on the outside of the fixing ring 9. A fixing bolt 15 is installed on the fixing ring 9. The adjusting holes 14 correspond to the fixing holes 8. The fixing bolt 15 passes through the adjusting holes 14 and the fixing holes 8. The end of the fixing bolt 15 is threaded with a fixing nut. The multiple fixing holes 8 are evenly distributed on the agitator rod 6, which can flexibly adjust the axial spacing of the fixing ring 9 to achieve the agitator blades 10 to be arranged at intervals or closely. The adjusting holes 14 on the fixing ring 9 can change the circumferential angle of the agitator blades 10, so that they are arranged in an alternating pattern to adapt to different smelting furnace 7 capacities and molten metal flow rates, and eliminate agitator dead zones. The cooperation between the fixing bolt 15 and the fixing nut 1 allows the agitator blades 10 to be quickly disassembled and installed, making it easy to clean or replace them individually.
[0026] Multiple limiting strips 13 are fixedly connected to the outer side of the stirring rod 6.

[0027] A second fixing bolt 19 is connected through the U-shaped cleaning frame 16. The second fixing bolt 19 is connected through the fixing hole 8. The end of the second fixing bolt 19 is threaded with a second fixing nut.

The second fixing bolt 19 and the second fixing nut enable the U-shaped cleaning frame 16 to be quickly installed and removed during cleaning without affecting the use of the stirring blade 10, thus improving the efficiency of equipment function switching.
[0028] Two replacement bolts 18 are threaded through the cleaning strip 17, and these bolts 18 are connected to the U-shaped cleaning frame 16. The replacement bolts 18 allow the cleaning strip 17 to be disassembled independently. When the cleaning strip 17 wears or ages, there is no need to replace the U-shaped cleaning frame 16, reducing maintenance costs. Furthermore, depending on the material of the furnace cavity of the smelting furnace 7, different types of cleaning strips 17, such as cleaning brushes or steel brushes, can be replaced to avoid scratching the inner wall of the furnace cavity and extend the service life of the smelting furnace 7. The mounting frame assembly includes a movable frame 1, an electric push rod 2 fixedly connected to the movable frame 1, and a movable plate 3 slidably connected to the movable frame 1. The output shaft end of the electric push rod 2 passes through the movable frame 1 and is fixedly connected to the movable plate 3. The motor 4 is fixedly connected to the movable plate 3. The movable frame 1 can drive the stirring mechanism to move flexibly and adapt to the smelting furnace 7 in different positions. The electric push rod 2 drives the movable plate 3 to slide up and down, realizing the lifting and lowering of the stirring mechanism. During stirring, the stirring blade 10 is lowered into the smelting furnace 7, and after stirring is completed, it is raised to the outside of the furnace, without obstructing the unloading of the smelting furnace 7. The movable plate 3 is fixed to the motor 4 to ensure that the motor 4 moves synchronously with the movable plate 3, ensuring a stable connection between the driving component and the stirring component.
[0029] In this embodiment, when it is necessary to stir the material in the smelting furnace 7, the moving frame 1 is pushed to drive the stirring mechanism to move. During the movement, the control module controls the two electric push rods 2 to start, driving the movable plate 3 to move upward. The movable plate 3 drives the motor 4 and the output rod 5 to move upward synchronously, so that the bottom of the output rod 5 is above the smelting furnace 7, avoiding the stirring mechanism from colliding with the smelting furnace 7 during the movement. When the stirring mechanism moves to the center position directly above the melting furnace 7, insert the connecting block 11 at the end of the stirring rod 6 into the slot of the output rod 5, and then use the connecting bolt 12 to pass through the output rod 5 and the connecting block 11 and thread it to complete the fixing of the stirring rod 6 and the output rod 5; Assemble the stirring blades 10 according to the height of the smelting furnace 7 and the material stirring requirements: Slide the fixing ring 9 from the upper or lower end of the stirring rod 6, align the limiting groove on the inner wall of the fixing ring 9 with the limiting strip 13 of the stirring rod 6, and slide it to the target position; According to the arrangement requirements of the stirring blades 10, adjust the fixing ring 9 so that the adjusting hole 14 corresponds to the fixing hole 8, use the fixing bolt 15 to pass through the adjusting hole 14 and the fixing hole 8, and tighten the fixing nut 1 to fix it; Multiple fixing holes 8 are evenly distributed, which can realize the stirring blades 10 are arranged at intervals or closely. The adjusting hole 14 can also make the stirring blades 10 staggered, which improves the stirring effect; Then, the electric push rod 2 is activated, driving the movable plate 3 to move downward, which in turn drives the motor 4, output rod 5, stirring rod 6 and stirring blade 10 to move downward. Holes are provided on the moving frame 1 at the position corresponding to the output rod 5 to ensure that the output rod 5 and stirring rod 6 move smoothly until the stirring blade 10 is located inside the smelting furnace 7. Then, the motor 4 is activated to drive the output rod 5, stirring rod 6 and stirring blade 10 to rotate, stirring the materials inside the smelting furnace 7. After stirring is completed, start the electric push rod 2 to drive the stirring mechanism to move upward, so that the stirring blade 10 is removed from the inside of the melting furnace 7 and located above the furnace opening. The melting furnace 7 is tilted by the power equipment of the melting furnace 7 itself, and the material is poured from the discharge port into the receiving device. After unloading is completed, the melting furnace 7 is reset and cooled. When the stirring blade 10 needs to be cleaned, the connecting bolt 12 can be unscrewed to remove the stirring rod 6 and the stirring blade 10 as a whole from the output rod 5 for cleaning; or the fixing bolt 15 can be unscrewed to slide the fixing ring 9 and the stirring blade 10 out from the lower end of the stirring rod 6 for separate cleaning. When the inside of the smelting furnace 7 needs to be cleaned, after removing the stirring blades 10, the U-shaped cleaning frame 16 is fitted from the lower end of the stirring rod 6. The fixing bolt 2 19 passes through the U-shaped cleaning frame 16 and the fixing hole 8, and the fixing nut 2 is tightened to fix it. The electric push rod 2 is started to move the U-shaped cleaning frame 16 down into the smelting furnace 7. The motor 4 is started to drive the stirring rod 6 and the U-shaped cleaning frame 16 to rotate. The cleaning strip 17 on the outside of the U-shaped cleaning frame 16 can be selected according to the model of the smelting furnace 7, such as a cleaning brush, a cleaning steel brush or a cleaning soft sheet, to clean the inside of the smelting furnace 7. When the cleaning strip 17 needs to be replaced, it can be removed and replaced by unscrewing the replacement bolt 18.
