Description

Technical Field

[0001] This invention relates to the field of aluminum alloy casting technology, specifically to a diversion device and casting system for semi-continuous alloy casting. Background Technology

[0002] Aluminum alloys are alloys with aluminum as the base and a certain amount of other alloying elements added. They are one of the light metal materials. The main alloying elements are copper, silicon, magnesium, zinc or manganese, followed by nickel, iron, titanium or chromium, etc. There are many varieties, and most of them can be hardened by heat treatment and aging. Due to the low specific gravity of aluminum, the strength per unit weight of aluminum alloys is close to that of high-quality steel.

[0003] In aluminum alloy preparation, a semi-continuous casting process is often used. First, the molten alloy flows out of the high-temperature furnace, flows into the distribution device through the liquid transfer device, and then flows out from the hole in the side wall of the distribution device into the crystallizer for cooling. The motor slowly carries the solidified part in the crystallizer into the lower vertical shaft and keeps it water-cooled, while there is always molten alloy in the crystallizer that needs to be cooled.

[0004] However, most of the existing aluminum alloy preparation processes use fixed distribution plates. During the preparation process, the aluminum alloy liquid is prone to oxide scale formation when it comes into contact with air. Furthermore, the fixed distribution plate can easily create dead zones inside the crystallizer, affecting the casting effect. Summary of the Invention

[0024] A liquid inlet pipe 110 is installed on the top of the lifting plate 100. The rotary diversion assembly 200 includes a motor 210 installed on the top of the lifting plate 100 and a zirconia-based diversion ring 220 rotatably connected to the bottom of the lifting plate 100. The liquid inlet pipe 110 is connected to the interior of the zirconia-based diversion ring 220. Multiple diversion holes 220a are opened on the outer wall of the zirconia-based diversion ring 220 near the bottom. A top plate 220b is installed on the top of the zirconia-based diversion ring 220. A base plate 220c is installed at the bottom, and a flow divider cone 220c-1 is installed on top of the base plate 220c. A lifting assembly 300 is installed on top of the lifting plate 100 and connected to the zirconia substrate flow divider ring 220. When the motor 210 drives the zirconia substrate flow divider ring 220 to rotate, it drives the lifting assembly 300 to push the lifting plate 100 upward. A conveying assembly 400 is installed on top of the lifting plate 100 and connected to the zirconia substrate flow divider ring 220. When the zirconia substrate flow divider ring 220 rotates, it drives... The conveying assembly 400 continuously delivers external molten aluminum alloy to the inlet pipe 110, and then through the inlet pipe 110 to the interior of the zirconia substrate diversion ring 220. The unblocking assembly 500 is installed on the outer wall of the top plate 220b, and the number of unblocking assemblies 500 matches the number of diversion holes 220a. When the zirconia substrate diversion ring 220 rotates, it drives the unblocking assemblies 500 to unblock the corresponding diversion holes 220a. In use, the motor 210 is started to rotate the zirconia substrate diversion ring 220. The zirconia matrix distribution ring 220 rotates, and the conveying component 400 drives the external aluminum alloy liquid to be conveyed into the liquid inlet pipe 110 and then into the zirconia matrix distribution ring 220. When the zirconia matrix distribution ring 220 rotates, centrifugal force is used to discharge the internal aluminum alloy liquid through the distribution hole 220a. During the rotation, the unblocking component 500 is driven to unblock the inside of the distribution hole 220a to prevent the inside of the distribution hole 220a from being blocked by waste residue, which would affect the distribution effect.

[0025] A third gear 210a is rotatably connected to the bottom of the lifting plate 100, and the third gear 210a is connected to the output end of the motor 210. A fourth gear 220b-1 is installed on the top of the top plate 220b, and the fourth gear 220b-1 is coaxial with the top plate 220b. The fourth gear 220b-1 is rotatably connected to the bottom of the lifting plate 100, and the fourth gear 220b-1 meshes with the third gear 210a. An extension tube 110a is installed at the bottom of the lifting plate 100, and the extension tube 110a is coaxial with the liquid inlet tube 110 and is connected to the liquid inlet tube 110. The extension tube 110a passes through the liquid inlet hole 220b-2 and extends into the zirconia matrix distribution ring 220. The starting motor 210 drives the third gear 210a to rotate. When the third gear 210a rotates, it drives the fourth gear 220b-1 and the top plate 220b to rotate. The top plate 220b drives the zirconia matrix distribution ring 220 and the bottom plate 220c to rotate. The aluminum alloy liquid is transported to the inside of the zirconia matrix distribution ring 220 through the extension tube 110a and discharged from the distribution hole 220a by centrifugal force when the zirconia matrix distribution ring 220 rotates.

[0026] The lifting assembly 300 includes two first fixing plates 310 symmetrically mounted on the top of the lifting plate 100 and a slider 320 located between the two first fixing plates 310. A threaded rod 310a is rotatably connected between the two first fixing plates 310. A threaded hole 320a is opened on the side wall of the slider 320, through which the threaded rod 310a rotatably passes. A connecting rod 320b is located at the top of the slider 320, and its bottom end is rotatably connected to the top of the slider 320. A first helical gear 310a-1 is rotatably connected to the side wall of one of the first fixing plates 310. The first helical gear 310a-1 is coaxially fixedly connected to the threaded rod 310a. A third pulley 330 is rotatably connected to the top of the lifting plate 100. A second helical gear 330a is mounted on the top of the third pulley 330, and the second helical gear 330a meshes with a first helical gear 310a-1. A first gear 130 is rotatably connected to the bottom of the lifting plate 100, and a first pulley 130a is rotatably connected to the top of the lifting plate 100. The first pulley 130a and the first gear 130 are coaxially fixedly connected. A second gear 140 is rotatably connected to the top of the lifting plate 100, and a second pulley 140a is mounted on the top of the second gear 140. The first pulley 130a and the second pulley 140a are connected by a belt. A fifth gear 340 is rotatably connected to the lifting plate 100. The fifth gear 340 meshes with the second gear 140. The fifth gear 340 is connected to the third pulley 330 via a belt. There are two lifting components 300, symmetrically located on the top of the lifting plate 100. Both fifth gears 340 mesh with the second gear 140. When the zirconia matrix distribution ring 220 and the fourth gear 220b-1 rotate, the fourth gear 220b-1 drives the first gear 130 and the first pulley 130a to rotate. When the first pulley 130a rotates, it drives the second pulley 140a and the second gear 140 to rotate via the belt. When the second gear 140 rotates, it drives the fifth gear 340 to rotate. When the fifth gear 340 rotates, it drives the third pulley 330 and the second helical gear 330a to rotate via a belt. When the second helical gear 330a rotates, it drives the first helical gear 310a-1 and the threaded rod 310a to rotate. When the threaded rod 310a rotates, it uses a screw structure to push the slider 320 to move from the top of the lifting plate 100 to the outer wall of the lifting plate 100. The two sliders 320 move in opposite directions. The other end of the connecting rod 320b is rotatably connected to the external fixed frame. When the two sliders 320 move away from each other, the connecting rod 320b pulls the lifting plate 100 upward. The lifting plate 100 drives the zirconia matrix distribution ring 220 to move upward.

[0027] The conveying assembly 400 includes two fixed pipes 410 symmetrically mounted on the top of the lifting plate 100 and a floating plate 420 located between the two fixed pipes 410. A first conveying pipe 410a is installed on the top of the fixed pipes 410, and the other end of the first conveying pipe 410a is connected to an external aluminum alloy liquid supply device. A first one-way valve 410a-1 is installed on the body of the first conveying pipe 410a. A second conveying pipe 410b is installed on the side wall of the fixed pipe 410, and the other end of the second conveying pipe 410b is connected to the inlet pipe 110. A second one-way valve 410b-1 is installed on the body of the second conveying pipe 410b. The fixed pipes 410 are filled with protective gas. Two pistons 420a are installed at both ends of the floating plate 420, and the two pistons 420a are located inside the two fixed tubes 410 respectively. A guide groove 420b is opened at the center of the top of the floating plate 420. A turntable 140b is installed on the top of the second pulley 140a, and an eccentric shaft 140b-1 is installed on the top of the turntable 140b. The eccentric shaft 140b-1 is slidably connected inside the guide groove 420b. When the second gear 140 rotates, it drives the second pulley 140a and the turntable 140b to rotate. The eccentric shaft 140b-1 rotates with the turntable 140b. The eccentric shaft 140b-1 slides inside the guide groove 420b and pushes the floating plate 420 to reciprocate on the top of the lifting plate 100. When the floating plate 420 slides into the right-side fixed tube 410, the right-side piston 420a moves into the right-side fixed tube 410, and the left-side piston 420a moves outward from the left-side fixed tube 410. At this time, the left-side first check valve 410a-1 opens and the second check valve 410b-1 closes, allowing the left-side first delivery pipe 410a to deliver external aluminum alloy liquid into the fixed tube 410. Simultaneously, the right-side first check valve 410a-1 closes and the second check valve 410b-1 opens, allowing the aluminum alloy liquid inside the right-side fixed tube 410 to be delivered to the inlet pipe 110 via the second delivery pipe 410b. Conversely, when the floating plate 420 slides into the left-side fixed tube 410, the piston 420a moves outward from the left-side fixed tube 410. When in motion, the left piston 420a moves into the left fixed tube 410, and the right piston 420a moves out of the right fixed tube 410. At this time, the right first check valve 410a-1 opens and the second check valve 410b-1 closes. The right first delivery tube 410a delivers the external aluminum alloy liquid into the fixed tube 410. At the same time, the left first check valve 410a-1 closes and the second check valve 410b-1 opens. The aluminum alloy liquid inside the left fixed tube 410 is delivered to the inlet tube 110 through the second delivery tube 410b. This ensures that the aluminum alloy liquid is continuously delivered to the zirconia matrix distribution ring 220 through the inlet tube 110 and the extension tube 110a.

[0028] The unblocking assembly 500 includes an extension plate 510 installed on the outer wall of the top plate 220b and a movable plate 520 located below the extension plate 510. Unblocking rods 520b are installed on the side wall of the movable plate 520, each rod corresponding to a diversion hole 220a and coaxial with the corresponding diversion hole 220a. A sixth gear 510a is rotatably connected to the top of the other end of the extension plate 510. A fixing ring 120 is installed at the bottom of the lifting plate 100, and two arc-shaped racks 120a are symmetrically installed on the inner wall of the fixing ring 120. The arc-shaped racks 120a are one-sixth of a circle. Two second gears 510a are symmetrically installed at the bottom of the extension plate 510. A fixed plate 510b is rotatably connected to two second fixed plates 510b via a reciprocating threaded rod 510b-1. A fourth helical gear 510b-2 is rotatably connected to the side wall of one of the second fixed plates 510b. The fourth helical gear 510b-2 is coaxially fixedly connected to the reciprocating threaded rod 510b-1. A third helical gear 510a-1 is rotatably connected to the bottom of the extension plate 510. The third helical gear 510a-1 is coaxially fixedly connected to the sixth gear 510a. The third helical gear 510a-1 meshes with the fourth helical gear 510b-2. A reciprocating threaded hole 520a is provided on the side wall of the movable plate 520. The reciprocating threaded rod 510b-1... 1. A reciprocating threaded hole 520a is rotated through the zirconia substrate distribution ring 220. When the zirconia substrate distribution ring 220 rotates, the top plate 220b rotates along with the zirconia substrate distribution ring 220, which in turn drives the outer extension plate 510 to rotate. When the extension plate 510 rotates past the arc-shaped rack 120a, the sixth gear 510a meshes with the arc-shaped rack 120a. The arc-shaped rack 120a drives the sixth gear 510a and the third helical gear 510a-1 to rotate. When the third helical gear 510a-1 rotates, it drives the fourth helical gear 510b-2 and the reciprocating threaded rod 510b-1 to rotate. When the reciprocating threaded rod 510b-1 rotates, it uses the screw structure to push the moving plate 52. The 0 and the unblocking rod 520b move back and forth, moving in and out of the corresponding diversion hole 220a to unclog the corresponding diversion hole 220a. This prevents residue from clogging the diversion hole 220a. Because there are two arc-shaped racks 120a symmetrically located on the inner wall of the fixed ring 120, only the sixth gear 510a passing through the arc-shaped rack 120a will rotate and drive the unblocking rod 520b to unclog the diversion hole 220a. This allows for continuous unblocking of multiple diversion holes 220a in batches, preventing clogging caused by residue without stopping the machine. Example 2

[0029] Figure 8 The diagram shown is a second structural schematic of an embodiment of a casting system for semi-continuous alloy casting according to the present invention. Please refer to [link / reference]. Figure 8Unlike the above embodiments, the casting system for semi-continuous alloy casting in this embodiment also includes a crystallization tank 600.

[0030] The lifting plate 100 is located inside the crystallization tank 600. A vertical shaft 610 is installed at the bottom of the crystallization tank 600, and a conveying motor 610a is installed on the pipe body of the vertical shaft 610. The crystallization tank 600 has a top cover 620 at the top, and a fixing block 620a is installed at the bottom of the top cover 620. The other end of the connecting rod 320b is rotatably connected to the bottom of the fixing block 620a. A first fixing seat 150 is installed on the top of the lifting plate 100, and a first magnetic chuck 150a is installed on the top of the first fixing seat 150. A second fixing seat 620b is installed at the bottom of the top cover 620 at a position corresponding to the first fixing seat 150, and a second magnetic chuck 620b-1 is installed at the bottom of the second fixing seat 620b. In use, the top cover 620 is connected to the top of the crystallization tank 600. Not shown in the figure, the top cover 620 has a connecting hole at the top, and the other end of the first conveying pipe 410a extends out from the connecting hole at the top of the top cover 620 and supplies external aluminum alloy liquid. When the equipment is connected and casting starts, liquid begins to be injected into the crystallization tank 600, and the liquid level continues to rise. At this time, the two sliders 320 move away from each other, and the connecting rod 320b pulls the sliders 320 to move the lifting plate 100 towards the top cover 620, keeping the zirconia matrix distribution ring 220 moving upward with the liquid level. This ensures that the zirconia matrix distribution ring 220 is always above or below the liquid level. Compared with the traditional distribution plate with a fixed height, this can greatly reduce the contact between the aluminum alloy liquid flowing out of the distribution hole 220a and the air, until the connecting rod 320b separates from the threaded hole 320a and the threaded rod 310a. At this time, the aluminum alloy liquid level inside the crystallization tank 600 is stable, and the first magnetic chuck 150a and the second magnetic chuck 620b-1 are attracted to limit the lifting plate 100. The conveying motor 610a slowly discharges the solidified part inside the crystallization tank 600 from the vertical shaft 610.

In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
