Description

Technical Field

[0001] This application belongs to the field of aluminum rod casting technology, and particularly relates to an aluminum rod casting system and its control method. Background Technology

[0002] Aluminum alloys are one of the most widely used non-ferrous metal structural materials in industry, and are extensively used in aviation, aerospace, automotive, machinery manufacturing, shipbuilding, and chemical industries. In the production and processing of aluminum alloy materials, the first step is alloying, followed by casting the molten aluminum alloy into round ingots, square ingots, and other shapes using casting equipment. Then, processing methods such as extrusion rolling, forging, and cooling are employed to transform it into aluminum alloy materials of various shapes required in the production field.

[0003] The existing aluminum rods are formed by deep well casting. After the aluminum rods are cast, the crystallizer and the ingot head need to be manually cleaned to remove any aluminum debris, which increases the labor intensity. This needs to be improved. Summary of the Invention

[0004] The purpose of this application is to address the aforementioned technical problems by providing an aluminum rod casting system and its control method, which can automatically clean aluminum debris from the crystallizer and reduce the labor intensity of manual labor.

[0005] This application provides an aluminum rod casting system, including a casting well, a distribution mold plate disposed at the opening of the casting well, a plurality of crystallizers mounted on the distribution mold plate, a lifting frame mounted in the casting well, and a dummy bar head mounted on the lifting frame and corresponding to and adapted to the crystallizers. The distribution mold plate has a flow channel connected to the crystallizers, and further includes: The liquid storage tank contains the mold release agent; An infusion port is connected to a liquid storage tank, and a pump body is provided between the infusion port and the liquid storage tank; A movable rod is installed on the ingot head, and a movable mechanism is provided between the movable rod and the ingot head; A drain outlet, which is connected to a liquid storage tank; The filtration system is located inside the liquid storage tank; A movable cavity is provided between the movable rod and the inlet head, and the inlet and outlet are both connected to the movable cavity.

[0006] The liquid storage tank stores the release agent. The inlet is connected to the bottom of the liquid storage tank via a pump, allowing the release agent to be sprayed out. Before aluminum rod casting, the crystallizer on the distribution mold plate is matched with the dummy ingot head. The movable rod is movably connected to the dummy ingot head. The movable mechanism uses an electric cylinder, pneumatic cylinder, or hydraulic cylinder, etc., to control the movement of the movable rod in the movable cavity. When the movable rod moves away from the crystallizer, the space in the movable cavity increases, allowing the inlet and outlet to connect with the crystallizer. As the release agent is continuously discharged from the inlet, the release agent in the space formed by the crystallizer and the dummy ingot head overflows upwards to the upper port of the crystallizer. Then, the inlet stops supplying the release agent. The mold release agent is discharged by opening the drain port. During the discharge process, aluminum debris on the surface of the crystallizer and the dummy ingot head is discharged along with the mold release agent. After the mold release agent is discharged, a layer of mold release agent adheres to the surface of the crystallizer and the dummy ingot head, which facilitates demolding after aluminum rod casting. The drain port is connected to the liquid storage tank, so that the mold release agent discharged from the crystallizer flows back into the liquid storage tank for recycling, improving resource utilization. The filtration mechanism uses filter screens and other filter materials to filter out aluminum debris in the mold release agent. Through the above structure, aluminum debris on the surface of the crystallizer and the dummy ingot head is discharged during the process of adding mold release agent to the crystallizer, reducing the labor intensity of manual labor.

[0007] Furthermore, both the infusion port and the drainage port are tangent to the movable cavity.

[0008] Furthermore, the movable lever includes: A protrusion is located at the center of the top of the movable rod, and the protrusion is arc-shaped.

[0009] Furthermore, the spindle head includes: Valve plate, installed at the drain port; A sealing element is placed on the valve plate and is adapted to the drain port; The drain outlet is provided with a groove, which is located on one side of the valve plate and communicates with the movable cavity.

[0010] Furthermore, the movable lever includes: A piston is movably connected to a movable rod, and the piston can form a compression chamber with the movable rod and the spindle head. The rod body is connected to the movable rod; The drive cylinder is connected between the rod and the piston.

[0011] Furthermore, the spindle head also includes: Inclined guide surfaces are placed on the infusion port and the drain port, respectively, and are close to the movable cavity. The limiting groove is placed on the ingot head; The first limiting block is movably placed on the movable rod and corresponds to the limiting groove; The second limiting block is movably placed on the movable rod and corresponds to the limiting groove.

[0012] Furthermore, it also includes: Cooling pipes are wound around the crystallizer and are connected to a water source; The nozzle is installed in the crystallizer and connected to the cooling pipe; The crystallizer is equipped with a cooling tank, and the nozzle is installed in the cooling tank.

[0013] This application also provides a control method for an aluminum rod casting system, the specific steps of which include: S1, Before casting, the crystallizer on the distribution mold plate is matched with the ingot head; S2, the release agent in the liquid storage tank is delivered to the crystallizer through the pump body. It is input from the liquid inlet and discharged from the liquid outlet. The release agent adheres to the wall of the crystallizer. S3, the release agent discharged through the drain port is filtered and then stored back into the liquid storage tank.

[0014] The beneficial effects of this application are: 1. By flooding the crystallizer with release agent and then draining and recycling it, the utilization rate of the release agent is improved and the labor intensity is reduced.

[0015] 2. By introducing a release agent into the crystallizer and then discharging it, aluminum debris present on the walls of the crystallizer and the surface of the ingot head can be removed, reducing the labor intensity of manual labor.

Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0020] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0021] The embodiments of this application are described in detail below with reference to the accompanying drawings, through specific examples and application scenarios. Example 1:

[0022] like Figures 1-4 As shown, this application provides an aluminum rod casting system, including a casting well 400, a distribution mold 100 disposed at the opening of the casting well 400, a plurality of crystallizers 200 mounted on the distribution mold 100, a lifting frame 410 mounted in the casting well 400, and a dummy bar head 300 mounted on the lifting frame 410 and corresponding to and adapted to the crystallizers 200. The distribution mold 100 has a flow channel 110 connected to the crystallizers 200, and further includes: Liquid storage tank 500, which stores mold release agent; An infusion port 310 is connected to a liquid storage tank 500, and a pump body 520 is provided between the infusion port 310 and the liquid storage tank 500. A movable rod 330 is installed on the spindle head 300, and a movable mechanism 600 is provided between the movable rod 330 and the spindle head 300; Drainage port 320, the drainage port 320 is connected to the liquid storage tank 500; The filter unit 510 is placed in the liquid storage tank 500; A movable cavity 301 is provided between the movable rod 330 and the inlet head 300, and the infusion port 310 and the drain port 320 are both connected to the movable cavity 301.

[0023] The liquid storage tank 500 stores the release agent. The inlet 310 is connected to the bottom of the liquid storage tank 500 via a pump body 520, allowing the release agent to be sprayed out. Before aluminum rod casting, the crystallizer 200 on the distribution mold plate 100 is matched with the ingot head 300. The movable rod 330 is movably connected to the ingot head 300. The movable mechanism 600 uses an electric cylinder, pneumatic cylinder, or hydraulic cylinder, etc., to control the movement of the movable rod 330 in the movable cavity 301. When the movable rod 330 moves away from the crystallizer 200, the space in the movable cavity 301 increases, allowing the inlet 310 and outlet 320 to communicate with the crystallizer 200. As the release agent is continuously discharged from the inlet 310, the release agent in the space formed by the crystallizer 200 and the ingot head 300 overflows upwards to the upper port of the crystallizer 200. Then, the delivery port 310 stops supplying the release agent, and the release agent is discharged by opening the drain port 320. During the discharge of the release agent, aluminum debris on the surface of the crystallizer 200 and the ingot head 300 is discharged along with the release agent. After the release agent is discharged, a layer of release agent adheres to the surface of the crystallizer 200 and the ingot head 300 to facilitate demolding after aluminum rod casting. The drain port 320 is connected to the liquid storage tank 500, so that the release agent discharged from the crystallizer 200 flows back to the liquid storage tank 500 for recycling, improving resource utilization. The filtration mechanism 510 uses filter screens and other filter materials to filter the aluminum debris in the release agent. Through the above structure, aluminum debris on the surface of the crystallizer 200 and the ingot head 300 is discharged during the process of adding release agent to the crystallizer 200, reducing the labor intensity of manual labor.

[0024] Furthermore, both the infusion port 310 and the drainage port 320 are tangent to the movable cavity 301.

[0025] By setting the inlet 310 and outlet 320 to be tangent to the active cavity 301, the release agent is kept rotating and flowing in the active cavity 301 and the crystallizer 200. The rotational flow speed in the crystallizer 200 is controlled by the input speed of the release agent. The higher the speed, the easier it is for aluminum chips to be washed away and fall to the bottom and be discharged by the outlet 320.

[0026] Furthermore, the movable lever 330 includes: A protrusion 331 is located at the top center of the movable rod 330, and the protrusion 331 is arc-shaped.

[0027] By setting the protrusion 331, the aluminum debris that sinks to the bottom is more easily discharged by the drain port 320 during the rotation and flow of the release agent, and is less likely to remain in the center position. The protrusion 331 is on the same axis as the movable rod 330, and the protrusion 331 and the movable rod 330 are integrally connected.

[0028] Furthermore, the spindle head 300 includes: Valve plate 321 is installed at drain port 320; The sealing element 322 is placed on the valve plate 321 and is adapted to the drain port 320; The drain port 320 is provided with a groove 323, which is located on one side of the valve plate 321 and communicates with the movable cavity 301.

[0029] The valve plate 321 is connected to a drive motor, control device, etc. The valve plate 321 controls the opening and closing of the drain port 320. When the delivery port 310 delivers the release agent, the valve plate 321 closes the drain port 320. When the release agent needs to be discharged, the valve plate 321 opens the drain port 320. The sealing element 322 is made of rubber or silicone and improves the sealing between the valve plate 321 and the drain port 320. The groove 323 facilitates the installation of the valve plate 321. Example 2:

[0030] like Figures 3-6 As shown, this application embodiment provides an aluminum rod casting system, which, in addition to including the above-mentioned technical features, further includes the following: The movable rod 330 includes: Piston 340 is movably connected to movable rod 330, and piston 340 can form compression chamber 341 between movable rod 330 and spindle head 300; Rod 332 is connected to movable rod 330; Drive cylinder 350 is connected between rod 332 and piston 340.

[0031] The piston 340 is movably connected to the movable rod 330, and the rod body 332 is integrally connected to the movable rod 330. The drive cylinder 350 is a pneumatic cylinder, hydraulic cylinder, or electric cylinder, etc. The drive cylinder 350 is installed and connected to the rod body 332 and the piston 340 by bolts or other fasteners. The drive cylinder 350 controls the movement of the piston 340 on the rod body 332. The piston 340, the rod body 332, and the ingot head 300 are all sealed. The movement of the piston 340 controls the change of the compression chamber 341. When the crystallizer 200 does not need to clean aluminum debris, the piston 340... The 40 movement connects the compression chamber 341 with the infusion port 310 and the slot 323. Then, the moving rod 330 is controlled to move, connecting the slot 323, the infusion port 310, the compression chamber 341 with the crystallizer 200, so that the moving rod 330 forms a slit with the slot 323 and the infusion port 310. The piston 340 is controlled by the drive cylinder 350 to move, so that the release agent in the compression chamber 341 is quickly sprayed out from the slot 323 and the infusion port 310, so that the release agent adheres to the wall of the crystallizer 200. The length of the piston 340 is greater than the height of the infusion port 310 and the slot 323.

[0032] Furthermore, the spindle head 300 also includes: The inclined guide surface 302 is placed on the infusion port 310 and the drain port 320 respectively, and is close to the side of the movable cavity 301; The limiting groove 303 is placed on the ingot head 300; The first limiting block 360 is movably placed on the movable rod 330 and corresponds to the limiting groove 303; The second limiting block 370 is movably placed on the movable rod 330 and corresponds to the limiting groove 303.

[0033] An inclined guide surface 302 is provided to guide the release agent to be sprayed from the inlet 310 and the slot 323. The limiting slot 303 is integrally connected to the ingot head 300 or connected by bolts. The first limiting block 360 and the second limiting block 370 both have structures for controlling the movable electromagnet. When the electromagnet structure is energized, the corresponding first limiting block 360 or second limiting block 370 extends from the movable rod 330 and cooperates with the limiting slot 303. When the first limiting block 360 extends and corresponds to the limiting slot 303, the movable rod 330 can connect the inlet 310 and the slot 323 to the crystallizer 200 after it moves. When the second limiting block 370 extends and corresponds to the limiting slot 303, the movable rod 330 can only connect the upper end of the slot 323 and the inlet 310 to the crystallizer 200 after it moves. Example 3:

[0034] like Figure 7 As shown, this application embodiment provides an aluminum rod casting system, which, in addition to the above-mentioned technical features, further includes: Cooling pipe 210 is wound around crystallizer 200, and cooling pipe 210 is connected to water source; Nozzle 220 is installed in crystallizer 200 and connected to cooling pipe 210; The crystallizer 200 is provided with a cooling tank 230, and the nozzle 220 is installed in the cooling tank 230.

[0035] Cooling pipe 210 is connected to a water source, and cooling water flows through cooling pipe 210 to enable rapid cooling of crystallizer 200. Nozzle 220 is installed in cooling tank 230 and connected to cooling pipe 210. When aluminum rod is pulled downward from casting, cooling water is sprayed through nozzle 220 for secondary cooling, improving aluminum rod casting efficiency. When dummy head 300 is engaged with crystallizer 200, the cooling liquid sprayed by nozzle 220 is applied to dummy head 300, increasing the cooling efficiency of dummy head 300 in contact with molten aluminum. Example 4:

[0036] This application also provides a control method for an aluminum rod casting system, the specific steps of which include: S1. Before casting, the crystallizer 200 on the distribution mold plate 100 is matched with the ingot head 300. S2, the release agent in the liquid storage tank 500 is transported to the crystallizer 200 through the pump body 520, and is input from the inlet 310 and discharged from the outlet 320. The release agent adheres to the wall surface of the crystallizer 200. S3, the release agent discharged through the drain port 320 is stored back into the liquid storage tank 500 after passing through the filter mechanism 510.

[0037] The process of flooding the crystallizer 200 with release agent and then draining and recycling it improves the utilization rate of the release agent and can remove aluminum debris present on the wall of the crystallizer 200 and the surface of the ingot head 300. At the same time, the release agent adhering to the wall of the crystallizer 200 can reduce the labor intensity of manual labor.
