Description

Technical Field

[0001] This invention relates to the field of aluminum casting technology, and more specifically to an aluminum processing and casting apparatus. Background Technology

[0002] Aluminum alloys, with their low density, high specific strength, excellent thermal and electrical conductivity, and corrosion resistance, have become a core material for lightweighting and structural-functional integration in modern industry. As key components for mechanical structures and electrical connections, the forming quality of aluminum columns determines the performance and cost of downstream products. In existing aluminum casting processes, the mainstream method for casting aluminum columns involves injecting molten aluminum alloy into a mold and then solidifying it.

[0003] Chinese Patent Publication No. CN215508950U discloses a casting device for a novel aluminum forming process, comprising a fixed frame; a support rod is fixedly connected to the bottom of the fixed frame, a water tank is fixedly connected to the inner bottom wall of the fixed frame, a condenser pipe is fixedly connected to the inner bottom wall of the water tank, and a heat dissipation pipe is fixedly connected to one side of the water tank; through the structural design of the fixed frame, electric push rod, heat dissipation plate, mold body, side plate, connecting frame, motor, screw, threaded pipe, fixed rod, storage box, discharge pipe, discharge valve, and casting head, the casting device achieves the function of facilitating casting, solves the problem of inconvenient casting of general casting devices, facilitates the casting of aluminum raw materials, avoids wasting working time and reducing the efficiency of aluminum processing due to inconvenient casting, meets the working time requirements, and improves the efficiency of the casting device.

[0004] The device adopts a single-mold independent casting operation mode, which can only realize single-station single-time forming processing. The overall operation cycle is limited, and the work efficiency is difficult to meet the needs of large-scale continuous production.

[0005] Meanwhile, in the traditional casting process, impurities are first removed in a large melting furnace (such as slag removal process), and then the treated molten aluminum is transferred and poured into the mold. Although this process can remove slag, fine slag still remains inside the molten aluminum. The slag has a loose and porous structure, which will affect the product quality. In addition, during the pouring process, gas remains in the molten aluminum (in the form of tiny bubbles). During solidification, it precipitates and forms pores and looseness, which seriously reduces the density and overall molding quality of the cast workpiece. Summary of the Invention

[0006] In view of the above situation and to overcome the defects of the prior art, the present invention provides an aluminum processing and casting apparatus to solve the above problems.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An aluminum processing and casting apparatus includes a housing and a mold cylinder. A rotating platform is rotatably connected to the top of the housing. Several rotatable cylindrical annular supports are arranged circumferentially along the axis of the rotating platform. The mold cylinder is rotatably disposed inside the annular supports. The housing is provided with a rotating mechanism and a self-rotating mechanism for driving the annular supports to rotate in the forward or reverse direction. The self-rotating mechanism is linked to the rotating platform, and the driving part of the rotating mechanism is driven to drive the rotating platform. During the rotation of the rotating platform by the rotating mechanism, the self-rotating mechanism is driven to make the annular supports rotate in the forward or reverse direction.

[0008] The annular support is coaxially connected to a first one-way bearing and a second one-way bearing. The first one-way bearing is coaxially connected to the mold cylinder, and a positioning base plate is rotatably connected to the bottom of the mold cylinder. The second one-way bearing is coaxially connected to the positioning base plate. Several ejector pins are slidably connected through the positioning base plate. The interior of the housing is equipped with a cooling spray head and a pushing mechanism for ejecting the ejector pins. The first and second one-way bearings rotate in opposite directions. When the annular support rotates forward, the first one-way bearing is in a free-spinning state, and the second one-way bearing drives the positioning base plate to rotate synchronously in the forward direction. When the annular support rotates in the reverse direction, the second one-way bearing is in a free-spinning state, and the first one-way bearing drives the mold cylinder to rotate synchronously in the reverse direction.

[0009] The ejector pin can be inserted into or removed from the mold cylinder. When the ejector pin is inserted into the mold cylinder, the positioning base plate rotates, which synchronously drives the ejector pin to rotate and stirs it at low speed inside the molten aluminum. This can disrupt the stability of bubbles inside the molten aluminum, promote the release of gas, and promote the floating and separation of impurities such as oxide slag in the molten aluminum. This achieves the degassing and impurity removal effect of aluminum smelting, thereby improving the quality of the finished aluminum column.

[0010] Preferably, the rotation mechanism includes planetary gears coaxially fixedly connected to an annular support, and a gear ring and a sun gear are fixedly connected inside the housing. Both the gear ring and the sun gear are coaxially arranged with the rotating platform. Both the gear ring and the sun gear are incomplete gears, and their teeth are adapted to the planetary gears.

[0011] Preferably, it also includes a planetary carrier disposed inside the housing, and an annular support is rotatably connected to the planetary carrier; when the planetary carrier rotates, the planetary gears intermittently mesh with the ring gear or the sun gear to drive the planetary gears to drive the annular support to rotate in the forward or reverse direction.

[0012] Preferably, the rotating mechanism includes a motor installed inside the housing, a reducer at the output end of the motor, and a rotating shaft at the output end of the reducer. The rotating shaft is coaxially and fixedly connected to the planetary carrier. When the motor starts, it drives the rotating shaft to rotate the planetary carrier, causing the planetary gears to rotate the annular support in either the forward or reverse direction. Preferably, the pushing mechanism includes a vibrating cylinder fixedly connected to the bottom of the positioning base plate, the bottom end of the ejector pin penetrates into the interior of the vibrating cylinder, and the end is fixedly connected to a movable plate; when the movable plate rises, it pushes the ejector pin to insert into the interior of the mold cylinder.

[0013] Preferably, a vibrating block is slidably connected inside the vibrating cylinder, and an elastic element is installed between the movable plate and the vibrating block.

[0014] Preferably, the bottom of the vibrating block has a plurality of first permanent magnets arranged in a circumferential array, and a second permanent magnet is installed on the inner bottom wall of the box. The cross-section of the second permanent magnet is arc-shaped, and the first permanent magnet and the second permanent magnet are magnetically repelled. When the vibrating block rotates, the corresponding areas of the first permanent magnet and the second permanent magnet change, and the magnetic repulsion between them increases or decreases, causing the vibrating block to sway up and down. When the positioning base plate rotates, the vibrating cylinder drives the vibrating block to rotate synchronously. The corresponding areas of the first and second permanent magnets change, and the magnetic repulsion between them fluctuates periodically. Combined with the elastic component providing elastic restoring force, the vibrating block swings back and forth, thus generating continuous vibration. The vibration energy is transmitted to the mold cylinder and acts on the molten aluminum inside, which can disrupt the steady state of bubbles inside the molten aluminum and promote the release of gas in the melt. At the same time, the vibration disturbance can cause oxides and slag particles in the molten aluminum to collide and aggregate with each other, reduce the adhesion force between slag particles and molten aluminum, accelerate the floating and separation of impurities, and improve the degassing and impurity removal effect of the molten aluminum.

[0015] Preferably, the top of the box is provided with a material injection funnel, and the output end of the material injection funnel matches the material injection port of the mold cylinder; the material injection funnel facilitates the worker to perform material injection operations inside the mold cylinder; it should be noted that, in actual use, a shut-off valve can be set at the output end of the material injection funnel to control the amount of material injected into the mold cylinder.

[0016] Preferably, there are multiple spray heads, and the housing is provided with a water supply pipe. The input end of the spray head is in fluid communication with the water supply pipe. The input end of the water supply pipe is connected to an external water source. When the external water source injects water into the water supply pipe, the water flows into the spray head through multiple output ports of the water supply pipe. The spray head sprays water to cool the mold cylinder.

[0017] Preferably, the bottom plate of the box is a grating plate, which enables the discharge of spray water.

[0018] The beneficial effects of this invention are as follows: 1. During the operation of this invention, the indexing rotation drive of the rotating platform enables the continuous flow operation of the multi-station mold cylinder 7, which can simultaneously complete the degassing, impurity removal and purification, spray cooling and ingot forming of aluminum melt, forming an integrated continuous operation process; compared with the traditional single mold independent casting process, the overall operation cycle is improved, which can meet the needs of large-scale, batch continuous production.

[0019] 2. During the operation of this invention, the aluminum melt inside the cylinder is stirred at low speed by rotating the ejector pin, which can disrupt the stability of the bubbles inside the aluminum melt, promote the release of gas, and at the same time promote the floating and separation of impurities such as oxide slag in the aluminum melt, thereby achieving the degassing and impurity removal effect of aluminum smelting, and thus improving the quality of the finished aluminum column.

[0020] 3. During the operation of this invention, continuous vibration is generated. The vibration energy is transmitted to the mold cylinder and acts on the aluminum melt inside. This can disrupt the steady state of the bubbles inside the aluminum melt, promote the release of gas in the melt, and at the same time, the vibration disturbance can cause the floating slag particles in the aluminum melt to collide and aggregate with each other, reduce the adhesion force between the slag particles and the aluminum melt, accelerate the floating and separation of impurities, and further improve the degassing and impurity removal effect of the aluminum melt.

[0021] 4. When the mold cylinder of the present invention is transported to the spray cooling station, the mold cylinder rotates along with the rotating platform and rotates on its own axis, which can rapidly cool the mold cylinder from all directions and improve the cooling effect.

[0029] The following will be for reference. Figures 1 to 6 The various embodiments of the present invention will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0030] An aluminum processing and casting apparatus, such as Figures 1-3 As shown, the device includes a housing 1 and a mold cylinder 7. A rotating platform 2 is rotatably connected to the top of the housing 1. Several rotatable cylindrical annular supports 3 are arranged in a circular array along the axis of the rotating platform 2. The mold cylinder 7 is rotatably disposed inside the annular supports 3. The housing 1 is provided with a rotating mechanism and a self-rotating mechanism for driving the annular supports 3 to rotate in the forward or reverse direction. The self-rotating mechanism is linked to the rotating platform 2, and the driving part of the rotating mechanism is driven to drive the rotating platform 2. During the rotation of the rotating platform 2 by the rotating mechanism, the self-rotating mechanism is driven to make the annular supports 3 rotate in the forward or reverse direction.

[0031] like Figure 2 and Figure 3 As shown, a first one-way bearing 8 and a second one-way bearing 9 are coaxially connected to the annular bracket 3. The first one-way bearing 8 is coaxially connected to the mold cylinder 7, and a positioning base plate 10 is rotatably connected to the bottom of the mold cylinder 7. The second one-way bearing 9 is coaxially connected to the positioning base plate 10. In this embodiment, the first one-way bearing 8 and the second one-way bearing 9 rotate in opposite directions. When the annular bracket 3 rotates forward, the first one-way bearing 8 is in a free-spinning state, and the second one-way bearing 9 drives the positioning base plate 10 to rotate forward synchronously. When the annular bracket 3 rotates in the reverse direction, the second one-way bearing 9 is in a free-spinning state, and the first one-way bearing 8 drives the mold cylinder 7 to rotate in the reverse direction synchronously.

[0032] like Figure 3 and Figure 5As shown, several ejector pins 15 are slidably connected through the positioning base plate 10. The ejector pins 15 of this device are movable, so that the ejector pins 15 can be inserted into the mold cylinder 7 or pulled out of the mold cylinder 7. When the ejector pins 15 are inserted into the mold cylinder 7, the positioning base plate 10 rotates, which will synchronously drive the ejector pins 15 to rotate and perform low-speed stirring inside the aluminum melt. This can disrupt the stability of bubbles inside the aluminum melt, promote the release of gas, and at the same time promote the floating and separation of impurities such as oxide slag in the aluminum melt, thereby achieving the degassing and impurity removal effect of aluminum smelting, and thus improving the quality of the finished aluminum column.

[0033] like Figure 3 and Figure 4 As shown, the rotation mechanism includes planetary gears 4 coaxially fixedly connected to the annular support 3. A gear ring 5 and a sun gear 6 are fixedly connected inside the housing 1. Both the gear ring 5 and the sun gear 6 are coaxially arranged with the rotating platform 2. Both the gear ring 5 and the sun gear 6 are incomplete gears, and their teeth are adapted to the planetary gears 4. It also includes a planet carrier 14 disposed inside the housing 1, with the annular support 3 rotatably connected to the planet carrier 14. When the planet carrier 14 rotates, the planetary gears 4 intermittently mesh with the gear ring 5 or the sun gear 6, causing the planetary gears 4 to drive the annular support 3 to rotate forward or backward. In this embodiment, a resistance bearing is provided at the connection between the annular support 3 and the planet carrier 14. When the planetary gears 4 revolve to the meshing gap period, they enter a period of rotational rest. Through the setting of the resistance bearing, the planetary gears 4 are locked at the angle and never deviate, ensuring that the planet carrier 14 can subsequently mesh accurately again, preventing the planetary gears 4 from freely deflecting during rest and causing subsequent failure to mesh properly.

[0034] like Figure 2 and Figure 3 As shown, the rotating mechanism includes a motor 12 installed inside the housing 1. The motor 12 is a servo motor. The output end of the motor 12 is equipped with a reducer 24. The output end of the reducer 24 is equipped with a rotating shaft 13. The rotating shaft 13 is coaxially and fixedly connected to the planetary carrier 14. When the motor 12 starts, it drives the rotating shaft 13 to drive the planetary carrier 14 to rotate, so that the planetary gear 4 drives the annular support 3 to rotate in the forward or reverse direction.

[0035] like Figure 3 and Figure 5 As shown, the box 1 is equipped with a pushing mechanism for ejecting the ejector pin 15. The pushing mechanism includes a vibrating cylinder 22 fixedly connected to the bottom of the positioning base plate 10. The bottom end of the ejector pin 15 is inserted into the vibrating cylinder 22, and the end is fixedly connected to a movable plate 16. When the movable plate 16 rises, it pushes the ejector pin 15 into the mold cylinder 7.

[0036] like Figure 3 , Figure 5 and Figure 6As shown, a vibrating block 23 is slidably connected inside the vibrating cylinder 22, and an elastic element 17 is installed between the movable plate 16 and the vibrating block 23. In this embodiment, the elastic element 17 is a spring. Several first permanent magnets 20 are arranged in a circular array at the bottom of the vibrating block 23, and a second permanent magnet 21 is installed on the inner bottom wall of the box 1. The cross-section of the second permanent magnet 21 is arc-shaped. When the first permanent magnet 20 and the second permanent magnet 21 correspond, they repel each other magnetically.

[0037] When the positioning base plate 10 rotates, the vibrating cylinder 22 drives the vibrating block 23 to rotate synchronously. The corresponding areas of the first permanent magnet 20 and the second permanent magnet 21 change, and the magnetic repulsion between them fluctuates periodically. With the elastic element 17 providing elastic restoring force, the vibrating block 23 swings back and forth, thus generating continuous vibration. The vibration energy is transmitted to the mold cylinder 7 and acts on the aluminum melt inside, which can disrupt the steady state of the bubbles inside the aluminum melt and promote the release of gas in the melt. At the same time, the vibration disturbance can cause oxides and slag particles in the aluminum melt to collide and aggregate with each other, reduce the adhesion force between slag particles and aluminum melt, accelerate the floating and separation of impurities, and improve the degassing and impurity removal effect of the aluminum melt.

[0038] like Figures 1-3 As shown, the top of the box 1 is provided with a material injection funnel 19. The output end of the material injection funnel 19 is matched with the material injection port of the mold cylinder 7. The setting of the material injection funnel 19 makes it convenient for the staff to perform material injection operations inside the mold cylinder 7. It should be noted that in actual use, a shut-off valve can be set at the output end of the material injection funnel 19 to control the amount of material injected into the mold cylinder 7.

[0039] like Figure 3 and Figure 5 As shown, the interior of the box 1 is equipped with multiple spray heads 11 for cooling. The box 1 is equipped with a water supply pipe 25, the input end of which is connected to an external water source. The input end of the spray head 11 is in fluid communication with the water supply pipe 25. The bottom plate of the box 1 is a grid plate 18, which enables the spray water to be discharged.

[0040] When the mold cylinder 7 moves to the spray cooling station, the spray head 11 continuously sprays cooling water towards the outer peripheral wall of the mold cylinder 7 to rapidly cool the mold cylinder 7, causing the molten aluminum inside the mold cylinder 7 to solidify quickly, greatly shortening the workpiece forming cycle and effectively improving the overall continuous operation efficiency and production rhythm.

[0041] During the use of this device, motor 12 operates in a stepping manner, that is, the rotating platform 2 carries the mold cylinder 7 in a stepping rotational motion.

[0042] It should be noted that when the mold cylinder 7 is located at the injection station, the first permanent magnet 20 and the second permanent magnet 21 on the mold cylinder 7 are in a corresponding state. At this time, the elastic element 17 is in a compressed state, and the ejector pin 15 is inserted into the mold cylinder 7.

[0043] Workers inject molten aluminum into the mold cylinder 7 through the injection funnel 19. When the rotating platform 2 rotates again, the planetary gear 4 on the mold cylinder 7 meshes with the teeth of the gear ring 5, causing the planetary gear 4 to drive the ring bracket 3 to rotate in the forward direction. At this time, the first one-way bearing 8 is in a free-spinning state, and the second one-way bearing 9 drives the positioning base plate 10 to rotate in the forward direction synchronously.

[0044] When the positioning base plate 10 rotates, the ejector pin 15 and the vibrating block 23 rotate. The ejector pin 15 stirs the aluminum melt in the cylinder at a low speed, which can disrupt the stability of the bubbles inside the aluminum melt, promote the release of gas, and at the same time promote the floating and separation of impurities such as oxide slag in the aluminum melt, thereby achieving the degassing and impurity removal effect of aluminum smelting and improving the quality of the finished aluminum column.

[0045] When the vibrating block 23 rotates, the corresponding areas of the first permanent magnet 20 and the second permanent magnet 21 change, and the magnetic repulsion between them fluctuates periodically. Combined with the elastic restoring force provided by the elastic element 17, the vibrating block 23 is able to swing back and forth (during the swinging of the vibrating block 23, under the action of the pushing force of the elastic element 17, the movable plate 16 is always attached to the bottom of the positioning base plate 10, that is, the ejector pin 15 will not swing up and down), thus generating continuous vibration. The vibration energy is transmitted to the mold cylinder 7 and acts on the aluminum melt inside, which can disrupt the steady state of the bubbles inside the aluminum melt, promote the release of gas in the melt, and at the same time, the vibration disturbance can cause the slag particles in the aluminum melt to collide and aggregate with each other, reduce the adhesion force between the slag particles and the aluminum melt, accelerate the floating and separation of impurities, and further improve the degassing and impurity removal effect of the aluminum melt.

[0046] When the rotating platform 2 rotates to the slag removal station of the mold cylinder 7, it stops rotating and the staff removes the floating slag with a cleaning scoop.

[0047] Then, the rotating platform 2 continues to rotate, conveying the mold cylinder 7 to the spray cooling station. It should be noted that at this point, the first permanent magnet 20 and the second permanent magnet 21 on the mold cylinder 7 no longer correspond. Under its own gravity, the ejector pin 15 moves downwards. Figure 3 As required, ejector pin 15 is automatically pulled out from mold cylinder 7.

[0048] The spray head 11 continuously sprays cooling water towards the outer peripheral wall of the mold cylinder 7, rapidly cooling the mold cylinder 7 and causing the molten aluminum inside the mold cylinder 7 to solidify quickly, greatly shortening the workpiece forming cycle and effectively improving the overall continuous operation efficiency and production rhythm.

[0049] It should be noted that when the mold cylinder 7 is conveyed to the spray cooling station, the planetary gear 4 on the mold cylinder 7 moves to disengage from the teeth of the gear ring 5 and engage with the teeth of the sun gear 6. At this time, when the mold cylinder 7 rotates with the rotating platform 2, the planetary gear 4 carries the ring bracket 3 to rotate in the opposite direction. The second one-way bearing 9 is in a free-spinning state, that is, the positioning base plate 10 will not make an ineffective rotational movement. The first one-way bearing 8 drives the mold cylinder 7 to rotate synchronously in the opposite direction. The rotation of the mold cylinder 7, combined with the spray cooling mechanism, can quickly cool the mold cylinder 7 in all directions, thus improving the cooling efficiency.

[0050] After the aluminum column is formed, the rotating platform 2 continues to rotate, transporting the mold cylinder 7 to the spray cooling station. When the first permanent magnet 20 and the second permanent magnet 21 on the mold cylinder 7 correspond to each other again, a magnetic repulsion force is generated between them, pushing the movable plate 16, causing the ejector pin 15 to insert into the mold cylinder 7 and eject the formed aluminum column, thus realizing automatic material discharge.

[0051] During operation, the rotating platform 2 drives the indexing rotation to achieve continuous operation of the multi-station mold cylinder 7. It can simultaneously complete processes such as degassing of molten aluminum, purification of impurities, spray cooling and ingot forming, forming an integrated continuous operation process. Compared with the traditional single-mold independent casting process, the overall operation cycle is improved, which can meet the needs of large-scale and batch continuous production.

[0052] It should be noted that in the description of this invention, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0053] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0054] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
