Description

Technical Field

[0001] The utility model belongs to the technical field of alloy casting, in particular to a casting automatic speed regulation system. Background Art

[0002] There are many casting methods for aluminum ingots. Each casting method has its own advantages and disadvantages and is suitable for different production requirements and aluminum alloy properties. In actual applications, other processes and technologies are also combined to improve product quality and production efficiency. For example:

[0003] Belt casting: A continuous casting machine is used to produce aluminum ingots. Molten aluminum is rapidly cooled and solidified in a circular pattern through a mold, forming an ingot. This method is highly efficient and suitable for large-scale production.

[0004] Caterpillar casting: Similar to belt casting, molten aluminum is cast and cooled through a mold driven by a crawler belt. This method is also suitable for continuous production.

[0005] Gravity casting: Molten aluminum is poured into a static mold and allowed to cool and solidify naturally. This method is relatively simple and suitable for small-batch production.

[0006] In crawler casting, the crawler belt drives the mold, while the distributor rotates, continuously distributing molten aluminum to the moving mold for continuous casting. However, the current crawler casting system has certain defects. The amount of molten aluminum from the distributor flowing into the mold per unit time is not constant. Because parameters such as the flow rate and flow rate of the molten aluminum inevitably change during continuous casting, the amount of molten aluminum distributed by the distributor to each mold is inconsistent. Ultimately, the weight of the cast aluminum ingots is inconsistent, with some being heavy and some being light. This seriously affects the quality requirements of the aluminum ingot molding and can result in substandard cast aluminum ingots. Utility Model Content

[0007] In response to the technical problems existing in the background technology, the utility model provides a casting automatic speed control system, which links the rolling mill and the distributor. Both are driven by the same drive mechanism, so that the speed of the rolling mill and the distributor can be adjusted synchronously to adapt to the changes in the flow rate and flow of the aluminum liquid, ensuring that the amount of aluminum liquid flowing into each mold is uniform, thereby ensuring the quality of aluminum ingot molding.

[0008] In order to achieve the above purpose, the technical solution provided by the utility model is:

[0009] A casting automatic speed regulation system includes a rolling mill and a distributor. The rolling mill includes a crawler conveyor assembly and a mold arranged on the crawler conveyor assembly. The crawler conveyor assembly is respectively connected to a conveying wheel, and the conveying wheel is fixed on a support through a rotating shaft. A driving mechanism is provided on one of the supports, and the driving mechanism is used to synchronously drive the rolling mill and the distributor to move.

[0010] Optionally, a transmission shaft is provided at one end of the distributor, a sprocket 1 is provided on the transmission shaft, and the sprocket 1 is arranged above the horizontal section of the crawler conveyor assembly and is connected to the crawler conveyor assembly for transmission; the driving mechanism includes a driving motor, and the driving motor is connected to the rotating shaft of the conveying wheel for transmission.

[0012] Optionally, a plurality of aluminum outlet pipes are provided on the circumference of the distributor, and an aluminum inlet is provided on one side of the distributor.

[0013] Optionally, the automatic casting speed regulation system further includes a chute assembly, which includes a first chute and a second chute connected to the bottom of the end of the first chute, and the second chute extends obliquely into the interior of the distributor through the aluminum inlet.

[0015] Optionally, it further includes a PLC processor, an aluminum tapping speed sensor and a rolling mill speed sensor, wherein the aluminum tapping speed sensor and the rolling mill speed sensor are electrically connected to the PLC processor respectively.

[0016] The utility model has the following advantages and beneficial effects:

[0017] The utility model provides an automatic casting speed regulation system that links the rolling mill and distributor, both of which are driven by the same drive mechanism. This allows the speeds of the rolling mill and distributor to be adjusted synchronously to adapt to changes in the flow rate and flow rate of the molten aluminum.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in combination with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0029] Example

[0030] like Figures 1 to 8 As shown, a casting automatic speed regulation system includes a rolling mill 1, a distributor 3 and other components.

[0031] like Figures 1 to 8As shown, the rolling mill 1 includes a crawler conveyor assembly 11 and a plurality of molds 12 arranged on the crawler conveyor assembly 11. The crawler conveyor assembly 11 can adopt a mechanism similar to a chain or a chain plate. The molds 12 are arranged on the corresponding chains or chain plates. The crawler conveyor assembly 11 is respectively connected to the conveying wheels 22. When the crawler conveyor assembly 11 adopts a chain or a chain plate mechanism, the conveying wheels 22 are sprockets that are connected to the chains or the chain plates. The conveying wheels 22 are fixed to the supports 2 via a rotating shaft 21. A driving mechanism is provided on one of the supports 2. The driving mechanism is used to synchronously drive the rolling mill 1 and the distributor 3 to move. That is, in the present invention, only one driving mechanism is used to drive the rolling mill 1 and the distributor 3 to move, thereby being able to synchronously adapt and adjust the movement speeds of the two.

[0032] Reference Figure 2 When the crawler conveyor assembly 11 is operating normally, the distributor 3 also rotates. After the current mold 12 is filled with aluminum liquid, it is transported forward and the next mold 12 is transported to the casting position. At the same time, the distributor 3 rotates and another aluminum discharge tube 31 is used to discharge aluminum. It can be foreseen that if the rotation speed of the distributor 3 and the speed of the rolling mill 1 cannot be adjusted synchronously, the following problems will arise: when the operating speeds of the distributor 3 and the rolling mill 1 are fixed, once the aluminum discharge speed flow rate of the aluminum discharge tube 31 changes, the amount of aluminum liquid entering the mold 12 will be inconsistent, and ultimately the weight of the aluminum ingots cast from each mold 12 will be different, resulting in unqualified casting. In addition, when the aluminum discharge flow rate and flow velocity change, adjusting the operating speed of the rolling mill 1 and the distributor 3 one by one will result in a delayed response and high difficulty in adjustment.

[0033] Therefore, the present invention provides an automatic casting speed control system that links the rolling mill 1 and the distributor 3. Both are driven by the same drive mechanism, so that the speeds of the rolling mill 1 and the distributor 3 can be adjusted synchronously to adapt to changes in the flow rate and flow rate of the molten aluminum. When the flow rate and flow rate of the molten aluminum decrease, the speeds of the rolling mill 1 and the distributor 3 are simultaneously reduced, extending the time it takes for the mold 12 to inject aluminum. When the flow rate and flow rate of the molten aluminum increase, the speeds of the rolling mill 1 and the distributor 3 are simultaneously increased, shortening the time it takes for the mold 12 to inject aluminum. This ensures that each moving mold 12 can receive a fixed amount of molten aluminum, thereby ensuring that the amount of molten aluminum flowing into each mold 12 is uniform, ensuring that the weight of the continuously cast aluminum ingots is consistent, and ensuring the quality of the aluminum ingot molding.

[0034] As a preferred embodiment of the present invention, Figure 1 、 2As shown in Figures 3 and 7, a transmission shaft 32 is provided at one end of the distributor 3, and a sprocket 33 is provided on the transmission shaft 32. The sprocket 33 is arranged above the horizontal section of the crawler conveyor assembly 11 and is connected to the crawler conveyor assembly 11 for transmission; the driving mechanism includes a driving motor 5, and a pulley 52 is provided on the output shaft of the driving motor 5. A pulley 52 is also provided on the rotating shaft 21 of the conveying wheel 22. The two pulleys 52 are connected for transmission by a belt 51, so that the conveying wheel 22 can be controlled to rotate by the driving motor 5, thereby driving the crawler conveyor assembly 11 to move, and then driving the mold 12 to move. When the crawler conveyor assembly 11 moves, the sprocket 33 is synchronously driven to rotate, thereby driving the distributor 3 to rotate.

[0035] As another preferred embodiment of the present invention, Figure 1 、 2 As shown in Figures 4 and 7, a transmission shaft 32 is provided at one end of the distributor 3, and a second sprocket 34 is provided on the transmission shaft 32. The second sprocket 34 is arranged above the horizontal section of the crawler conveyor assembly 11. The driving mechanism includes a driving motor 5, and a pulley 52 is provided on the output shaft of the driving motor 5. The rotating shaft 21 of the conveying wheel 22 is also provided with a pulley 52. ​​The two pulleys 52 are connected for transmission by a belt 51. The rotating shaft 21 of the conveying wheel 22 is also provided with a third sprocket 53. The third sprocket 53 and the second sprocket 34 are connected for transmission by a chain assembly 54. In this way, the conveying wheel 22 and the second sprocket 34 can be synchronously driven to rotate by the driving mechanism, thereby driving the mold 12 to move and driving the distributor 3 to rotate.

[0036] like Figures 1 to 8 As shown, a plurality of aluminum outlet tubes 31 are provided on the circumference of the distributor 3 , and an aluminum inlet 35 is provided on one side of the distributor 3 .

[0037] like Figures 1 to 8 As shown, the automatic casting speed regulation system of the present invention further includes a chute assembly 4, which includes a first chute 41 and a second chute 42 connected to the bottom end of the first chute 41, and the second chute 42 extends obliquely into the distributor 3 through the aluminum inlet 35.

[0038] Furthermore, the transmission shaft 32 is rotatably disposed on the mounting seat 6 .

[0039] like Figures 1 to 8As shown, the automatic casting speed regulation system of the present invention also includes a PLC control system 7, an aluminum discharge speed detection module 8, and a rolling mill speed detection module 9. The aluminum discharge speed detection module 8 is used to detect the aluminum discharge speed and flow rate of the aluminum liquid inside the chute assembly 4 (the first chute 41 or the second chute 42) and feed it back to the PLC control system 7. Equipment such as liquid level sensors and flow sensors can be used to detect the aluminum discharge situation; the rolling mill speed detection module 9 is used to detect the operating speed of the rolling mill 1 and feed it back to the PLC control system 7. Equipment such as speed sensors can be used to detect the rolling mill speed; the PLC control system 7 makes judgments and comparisons based on the received aluminum discharge speed, flow rate and the operating speed of the rolling mill 1, thereby adjusting the operating speeds of the rolling mill 1 and the distributor 3, so that the operating speeds of the rolling mill 1 and the distributor 3 match the aluminum discharge speed and flow rate.

[0040] The aluminum tapping speed detection module 8 includes an aluminum tapping speed sensor, and the rolling mill speed detection module 9 includes a rolling mill speed sensor. The aluminum tapping speed sensor and the rolling mill speed sensor are electrically connected to the PLC processor respectively.

[0041] When the rolling mill 1 is operating, its speed is synchronized with that of the distributor 3. Both speeds can be controlled by adjusting the rotational speed of the drive motor 5. Furthermore, to ensure a uniform amount of molten aluminum within each mold 12, each speed of the rolling mill 1 and the distributor 3 corresponds to a specific tapping speed and flow rate. This ensures minimal weight variation in the cast aluminum ingots. Therefore, when the tapping flow rate and flow velocity change, the operating speeds of the rolling mill 1 and the distributor 3 must be adjusted accordingly.

[0042] The casting system of the present invention can adaptively adjust the operating speed of the rolling mill 1 and the distributor 3 in real time according to the flow rate and flow rate of the aluminum output, thereby ensuring that the amount of aluminum liquid flowing into the mold 12 is uniform, and ultimately ensuring that the weight of each aluminum ingot cast continuously is uniform and the casting quality is guaranteed.

[0043] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
