Description

Technical Field

[0001] This utility model relates to the field of stirring and degassing technology, specifically to an aluminum molten metal stirring and degassing device. Background Technology

[0002] Casting is one of the earliest metal heat treatment techniques mastered by humankind, with a history of approximately six thousand years. China entered its golden age of bronze casting around 1700-1000 BC, achieving a remarkably high level of craftsmanship. Casting involves pouring liquid metal into a casting cavity tailored to the shape of the part, allowing it to cool and solidify to obtain the part or blank. The material being cast is often a metal that was originally solid but heated to a liquid state (e.g., copper, iron, aluminum, tin, and lead). The mold material can be sand, metal, or even ceramic. Different methods are used depending on the requirements. Slag and gases are easily generated during the casting process. If impurities and gases are not completely removed before casting, the casting is prone to defects such as porosity and looseness. Currently, most aluminum molten metal stirring and degassing devices used in casting have relatively fixed structures and cannot be adjusted. This can easily lead to uneven stirring during the stirring process, resulting in insufficient separation and removal of slag and gases, thus reducing the quality of the finished casting, causing a serious waste of human, material, and production resources, reducing work efficiency, and failing to meet current user needs.

[0003] To solve the above-mentioned technical problems, Chinese Patent No. CN220018472U discloses a casting aluminum molten stirring and degassing device, which includes a furnace body, a base fixedly connected to one side of the furnace body, a support fixedly connected to the top of the base, a lead screw fixedly connected to the bottom of the support, a first motor fixedly connected to the top of the lead screw, and a movable block movably connected to the front of the lead screw.

[0004] Although the aforementioned existing technical solutions can stir the molten aluminum to improve the quality of the finished castings, the stirring direction is singular, and stirring can only be carried out according to the rotation direction of the second motor. It is impossible to uniformly stir the molten aluminum in all parts of the furnace during degassing, which in turn affects the degassing effect and the product quality of subsequent castings.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example: Please refer to Figures 1-5 This utility model provides a technical solution:

[0024] A molten aluminum stirring and degassing device includes a base 1, a furnace body 2 mounted on top of the base 1, a connecting rod mounted on one end of the outer wall of the furnace body 2, an adjusting cylinder 3 mounted on one end of the connecting rod, a threaded rod 4 rotatably connected to the inner side of the adjusting cylinder 3, and an adjusting plate 5 threadedly connected to the outer side of the threaded rod 4. The adjusting plate 5 and the adjusting cylinder 3 are slidably connected. A first motor 6 is mounted on the top of the adjusting cylinder 3, and the drive end of the first motor 6 extends to the inner side of the adjusting cylinder 3 and is fixedly connected to one end of the threaded rod 4. A multi-directional stirring mechanism is mounted on the furnace body 2 and the adjusting plate 5. The multi-directional stirring mechanism includes a linkage component and a sliding stirring component. The device includes a sliding agitator and a bidirectional agitator. The linkage component drives the sliding agitator and the bidirectional agitator. The sliding agitator performs telescopic agitation, and the bidirectional agitator performs bidirectional agitation in the horizontal direction. In use, the linkage component drives the sliding agitator and the bidirectional agitator. The sliding agitator performs telescopic agitation, and the bidirectional agitator performs bidirectional agitation in the horizontal direction. The device has a simple structure and is easy to operate. It can perform multidirectional agitation on the molten aluminum in the furnace body 2 during degassing, making it more uniform and further ensuring the degassing effect and the quality of subsequent castings.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, one end of the second movable rod is fixedly connected to one end of one set of rotating rods 18, and the other end of the other set of rotating rods 18 is provided with a positioning groove 20. The bottom end of the first movable rod is equipped with a positioning block 19 that is slidably connected to the positioning groove 20. First, the first motor 6 is started to drive the threaded rod 4 to rotate, so that the adjusting plate 5 slides inside the adjusting cylinder 3, driving some parts of the multi-directional stirring mechanism to probe into the inside of the furnace body 2, so that the positioning block 19 engages with the positioning groove 20. After the engagement is completed, the position of the connecting seat 7 is above the molten aluminum.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the sliding agitator assembly includes a second motor installed at one end of the adjusting plate 5. A connecting seat 7 is installed at the drive end of the second motor. A first fixing plate 8 is installed on one side of the inner wall of the connecting seat 7. A first spring 9 is installed at both ends of one side of the first fixing plate 8. A sliding groove is opened on both sides of the inner wall of the mounting groove. A sliding plate 10 that is slidably connected to the sliding groove is installed on one side of the first spring 9. Then, the second motor is started to drive the connecting seat 7 to rotate. When rotating, the sliding plate 10 can slide inside the sliding groove according to the speed of the second motor, thereby driving the two sets of first springs 9 to be stretched. By adjusting the speed of the second motor, the first agitator 11 can be reciprocated and stirred inside the furnace body 2.

[0027] In this embodiment, as Figure 3 , Figure 4 and Figure 5 As shown, the bidirectional stirring assembly includes a first movable rod rotatably connected to the bottom of the connecting seat 7. A fixed box is fixedly sleeved on one end of the outer wall of the first movable rod. A second movable rod is installed at the center of the top of the movable seat 12. Multiple sets of stirring rods 15 are staggered and installed on one end of the outer walls of both the first and second movable rods. The linkage assembly includes a fixed rod installed on one side of the inner wall of the furnace body 2. A linkage cylinder 16 is installed on the other end of the fixed rod. A first bevel gear 17 is rotatably connected to one side of the inner wall of the linkage cylinder 16. Rotating rods 18 are rotatably connected to both ends of the linkage cylinder 16. Second bevel gears are installed on the opposite ends of the rotating rods 18. The connecting seat 7 is meshed with the first bevel gear 17. Furthermore, while the connecting seat 7 is rotating, it can also drive the first movable rod to rotate. When the first movable rod rotates, the positioning block 19 and positioning groove 20 that are engaged with it drive one set of rotating rods 18 to rotate. This causes the second bevel gear on the rotating rod 18 to drive the first bevel gear 17 that meshes with it to rotate. This, in turn, causes another set of second bevel gears and rotating rods 18 to rotate. When the other set of rotating rods 18 rotates, it can drive the movable seat 12 and the second movable rod to rotate together. The second movable rod and the first movable rod rotate in opposite directions, so that the stirring rods 15 on their outer walls can perform bidirectional stirring.

[0028] In this embodiment, as Figure 3 , Figure 4 and Figure 5 As shown, an extension rod is installed at one end of the sliding plate 10 away from the first fixed plate 8, and a first stirring plate 11 is installed at the other end of the extension rod. A movable seat 12 is rotatably connected to the bottom of the inner wall of the furnace body 2. A second stirring plate 13 is installed at both ends of the top of the movable seat 12. Multiple sets of mounting frames are embedded inside the first stirring plate 11 and the second stirring plate 13. Blades 14 are rotatably connected between the inner walls of the mounting frames. Furthermore, the connecting seat 7 can also drive the first movable rod to rotate while rotating. When the first movable rod rotates, the positioning block 19 and the positioning groove 20 that engage with it drive one set of rotating rods 18 to rotate, so that the second bevel gear on the rotating rod 18 drives the first bevel gear 17 that meshes with it to rotate, and then causes another set of second bevel gears and rotating rods 18 to rotate. When the other set of rotating rods 18 rotates, it can drive the movable seat 12 and the second movable rod to rotate together. The second movable rod and the first movable rod rotate in opposite directions, so that the stirring rods 15 on the outer walls of the two can perform bidirectional stirring.

[0029] The implementation principle of the aluminum molten metal stirring and degassing device in this application embodiment is as follows: The first motor 6 is started to drive the threaded rod 4 to rotate, causing the adjusting plate 5 to slide inside the adjusting cylinder 3. This causes some components of the multi-directional stirring mechanism to extend into the furnace body 2, so that the positioning block 19 engages with the positioning groove 20. After engagement, the connecting seat 7 is positioned above the molten aluminum. Then, the second motor is started to drive the connecting seat 7 to rotate. During rotation, the sliding plate 10 can slide inside the sliding groove according to the speed of the second motor, thereby stretching the two sets of first springs 9. By adjusting the speed of the second motor, the first stirring plate 11 can reciprocate back and forth inside the furnace body 2. Simultaneously, the connecting seat 7 rotates, also driving the first movable rod to rotate. When the first movable rod rotates, it cooperates with the engaged positioning block 19 and positioning groove 20 to drive one set of rotating rods. Rotating rod 18 causes the second bevel gear on the rotating rod 18 to drive the first bevel gear 17 meshing with it to rotate, which in turn causes another set of second bevel gears and rotating rod 18 to rotate. When the other set of rotating rod 18 rotates, it can drive the movable seat 12 and the second movable rod to rotate together. The second movable rod and the first movable rod rotate in opposite directions, so that the stirring rod 15 on their outer walls can perform bidirectional stirring. The second stirring plate 13 can also rotate together with the movable seat 12. The blades on the first stirring plate 11 and the second stirring plate 13 can be pushed when there is fluid, i.e., molten aluminum, passing by inside the mounting frame, and then stir the molten aluminum in the vicinity, which plays a further auxiliary stirring role. By using multi-directional stirring, the molten aluminum in the furnace body 2 is fully stirred, resulting in better degassing and ensuring the product quality during subsequent casting.

[0030] The control method of this utility model is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
