Description

Technical Field

[0001] The invention relates to the field of guide grooves for aluminum liquid processing, and in particular to a guide groove for aluminum liquid smelting and casting. Background Art

[0002] The molten aluminum guide trough is a key equipment in aluminum smelting and casting. It is responsible for safely and efficiently guiding the molten aluminum from the smelting furnace to subsequent equipment. It is usually made of special materials that are resistant to high temperatures and corrosion, and has the characteristics of efficient diversion, safety, reliability, and easy maintenance. With the continuous advancement of technology, the materials and manufacturing processes of the guide trough are constantly innovating. In the future, it may integrate more intelligent functions and pay more attention to environmental protection and energy saving.

[0003] The inventor of this application found that there are the following problems in the practical use process:

[0004] The existing aluminum liquid guide trough is used to guide the molten aluminum liquid and transport it to the next processing step. However, there is a problem in actual use. Specifically, the guide trough's guide effect usually utilizes the gravity of the aluminum liquid to guide the flow. Therefore, the guide trough as a whole is designed to be an inclined structure. At this time, if the guide trough is long, the flow rate of the aluminum liquid in some stages will be relatively accelerated, which may cause the aluminum liquid to splash or impact subsequent equipment. If the overall speed is too slow, it may affect the production efficiency. This is a substantial problem that needs to be solved urgently. The present invention urgently needs to design a guide trough with interception and speed reduction function to improve the guide effect of the aluminum liquid.

[0005] Therefore, it is necessary to provide an aluminum alloy smelting and casting aluminum liquid guide groove to solve the above technical problems. Summary of the invention

[0006] The technical problem to be solved by the present invention is that when facing a traditional long guide groove, the aluminum liquid flow rate is too fast in some stages, which easily causes aluminum liquid splashing. In view of the above defects of the prior art, a guide groove for aluminum alloy smelting and casting aluminum liquid is provided.

[0007] To achieve the above-mentioned purpose, the technical solution of the present invention is: a guide trough for aluminum alloy smelting and casting aluminum liquid, comprising a guide trough, the guide trough is provided with multiple sections and is in an end-to-end splicing structure, a cut-off assembly is provided on the top of the guide trough, the cut-off assembly comprises a support frame, a fixed plate is provided on the inner side of the support frame, a screw rod and a guide rod are provided on the fixed plate, a servo motor is installed on the top of the support frame, a movable plate is threadedly connected to the screw rod, a cut-off plate is rotatably provided on one side of the movable plate, an adjustment mechanism is provided above the movable plate and the cut-off plate, and the cut-off plate is in an inclined structure.

[0008] By adopting the above technical solution, the interception component is accurately installed on the top of the guide groove at the required position according to the specific use environment. As the aluminum liquid gradually flows in the guide groove, the servo motor is started, which immediately drives the screw rod to start rotating. Since a threaded connection design is adopted between the screw rod and the movable plate, the rotation of the screw rod will be effectively converted into the longitudinal movement of the movable plate.

[0009] It is further provided that the guide rod passes through the movable plate to limit the moving position of the movable plate, and the servo motor is electrically connected to an external power supply through a controller.

[0010] By adopting the above technical solution, the guide rod not only provides a stable moving trajectory for the movable plate, but also strictly limits its moving position, ensuring that the movable plate can move quickly and accurately along a predetermined direction under the drive of the servo motor, and effectively preventing the movable plate from deflecting or shaking during movement, thereby ensuring the accuracy and stability of the intercepting plate position adjustment.

[0011] It is further provided that the guide groove comprises a guide groove body, an accommodating groove is formed on the inner side of the guide groove body, and an inner lining is accommodated inside.

[0012] By adopting the above technical solution, it is ensured that the aluminum liquid can flow along a predetermined path, and the receiving groove formed on the inner side of the guide trough body provides space for the installation of the lining. The setting of the lining not only enhances the durability and corrosion resistance of the guide trough, but also can be replaced or repaired according to actual needs, thereby extending the service life of the guide trough.

[0013] It is further provided that pressure plates are bolted on both sides of the top of the guide trough body, and one side of the bottom surface of the pressure plate abuts against the top of the liner to fix the position of the liner.

[0014] By adopting the above technical solution, it is ensured that the liner can be firmly installed in the receiving groove, and the pressure plate is tightly connected to the guide groove body by bolts, and one side of its bottom surface is in contact with the top of the liner, thereby effectively fixing the position of the liner and preventing it from moving or shaking during the flow of aluminum liquid.

[0015] It is further provided that a liquid outlet is provided at the lower side of the inner lining at the very end, and the liquid outlet penetrates the guide groove body through a through opening and is connected with the next processing step device outside.

[0016] By adopting the above technical solution, it is ensured that the aluminum liquid can flow out smoothly and accurately when it flows to the end in the guide groove. The liquid outlet is the end point of the aluminum liquid flow, and its position and size are carefully designed to ensure that the aluminum liquid can flow out evenly and stably to avoid turbulence or liquid accumulation.

[0017] It is further provided that plug-in blocks and plug-in grooves are respectively provided at both ends of the lining, and adjacent linings are spliced ​​and connected via the plug-in blocks and the plug-in grooves.

[0018] By adopting the above technical solution, adjacent liners can be conveniently spliced ​​and connected through the plug-in blocks and the plug-in grooves. This connection method is not only simple and easy, but also firm and reliable, and can effectively ensure the continuity and sealing between the liners. During the aluminum liquid diversion process, the close combination of the plug-in blocks and the plug-in grooves can prevent the aluminum liquid from leaking, thereby ensuring the diversion effect of the diversion groove and the quality of the aluminum liquid.

[0019] It is further provided that a groove is formed on the inner side of the liner to provide a flow channel for the aluminum liquid, and the cross section of the groove is an overall "U"-shaped structure, and the intercepting plate is adapted to the groove.

[0020] By adopting the above technical solution, it is ensured that the aluminum liquid can flow stably and smoothly along the established path, avoiding adverse phenomena such as turbulence and vortex that may occur in the flow of the aluminum liquid, thereby improving the flow efficiency of the aluminum liquid and the diversion effect of the guide groove. The cross-section of the groove is an overall "U"-shaped structure. This structural design not only enhances the structural strength of the groove, but also enables the aluminum liquid to be more evenly distributed in the entire groove during the flow process, further improving the diversion stability and efficiency of the guide groove.

[0021] It is further provided that the adjustment mechanism comprises a first screw rod and a second screw rod, and one end of the first screw rod and the second screw rod are rotatably connected to the movable plate and the intercepting plate respectively through mounting ears.

[0022] By adopting the above technical solution, by twisting the threaded sleeve and utilizing the threaded connection characteristics between the threaded sleeve and the first screw and the second screw at both ends, the overall length of the threaded sleeve, the first screw and the second screw can be accurately adjusted, which provides a basis for adjusting the angle of the intercepting plate. In combination with the rotation characteristics of the movable plate and the intercepting plate, the angle of the intercepting plate can be flexibly adjusted according to actual needs.

[0023] It is further provided that the opposite ends of the first screw rod and the second screw rod are threadedly connected with a threaded sleeve, and the threaded sleeve is threadedly connected to the first screw rod and the second screw rod in a mirror image manner.

[0024] By adopting the above technical solution, this connection method is not only simple and reliable, but also easy to operate. By rotating the threaded sleeve, the relative position between it and the first screw rod and the second screw rod can be accurately adjusted, thereby achieving fine adjustment of the length of the entire adjustment mechanism.

[0025] It is further provided that a hexagonal block is fixedly provided on the outer side of the threaded sleeve to provide a force point for an external tool to act on the threaded sleeve.

[0026] By adopting the above technical solution, when the threaded sleeve needs to be rotationally adjusted, the presence of the hexagonal block enables the operator to use a wrench or other appropriate tools to easily and accurately apply force, thereby achieving precise control of the threaded sleeve, which not only improves the convenience of adjustment, but also ensures stability and safety during the adjustment process.

[0027] Compared with the related art, the aluminum alloy smelting casting aluminum liquid guide groove provided by the present invention has the following beneficial effects:

[0028] The present invention provides a guide trough for aluminum alloy smelting and casting aluminum liquid. Through the interception component, according to the specific use environment, a plurality of interception components are installed on the top of the guide trough at the required position. As the aluminum liquid gradually flows, the servo motor is started, which drives the lead screw to rotate. Since the lead screw and the movable plate are threadedly connected, the rotation of the lead screw is converted into the longitudinal movement of the movable plate. At the same time, the guide rod ensures that the movable plate remains stable during the movement without offset. As the movable plate moves, the interception plate is also longitudinally position-adjusted inside the accommodating groove. This adjustment process changes the cross-sectional shielding area of ​​the interception plate inside the slot, thereby realizing accurate control of the aluminum liquid flow rate inside the guide trough. Through this staged interception operation, the splashing of aluminum liquid caused by the excessively fast flow speed of the aluminum liquid in some stages can be effectively avoided, which not only improves the protection against the outside world, but also improves the transportation efficiency of the aluminum liquid, thereby ensuring the stability and safety of the entire guide process.

[0029] The invention provides an aluminum alloy smelting and casting aluminum liquid guide groove, which adopts an adjustment mechanism, and a threaded sleeve is screwed. By utilizing the threaded connection relationship between the threaded sleeve and a first screw rod and a second screw rod at two ends, the length of the entire adjustment mechanism can be accurately adjusted, so that the threaded sleeve, the first screw rod and the second screw rod constitute an integral body with adjustable length, which provides a basis for the angle adjustment of the intercepting plate. When the threaded sleeve is screwed, the change of its length will directly affect the position and angle of the movable plate and the intercepting plate connected with the first screw rod and the second screw rod, so as to achieve the adjustment of the angle of the intercepting plate. At the same time, since the movable plate and the intercepting plate can rotate relatively, when the length of the threaded sleeve is adjusted, the intercepting plate can adjust the angle according to actual needs without complicated disassembly or reassembly of the entire adjustment mechanism, so that the angle adjustment of the intercepting plate becomes fast and efficient, and can quickly adapt to different external use environments.

DETAILED DESCRIPTION

[0037] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings, in which typical embodiments of the present invention are shown.

[0038] Embodiment 1:

[0039] like Figure 1-6As shown, an aluminum alloy smelting and casting aluminum liquid guide trough of the present invention comprises a guide trough 1, which is provided with multiple sections and is in a head-to-tail splicing structure. A cut-off assembly 2 is provided on the top of the guide trough 1, and the cut-off assembly 2 comprises a support frame 201, a fixed plate 202 is provided on the inner side of the support frame 201, a screw rod 206 and a guide rod 207 are provided on the fixed plate 202, a servo motor 205 is installed on the top of the support frame 201, a movable plate 203 is threadedly connected to the screw rod 206, a cut-off plate 204 is rotatably provided on one side of the movable plate 203, an adjustment mechanism 3 is provided above the movable plate 203 and the cut-off plate 204, and the cut-off plate 204 is in an inclined structure, and the cut-off assembly 2 is accurately installed on the top of the guide trough 1 at a desired position according to the specific use environment. As the aluminum liquid moves in The liquid gradually flows in the guide groove 1, and the servo motor 205 is started, which then drives the screw rod 206 to start rotating. Since the screw rod 206 and the movable plate 203 are designed with a threaded connection, the rotation of the screw rod 206 will be effectively converted into the longitudinal movement of the movable plate 203. At the same time, the guide rod 207 plays a vital role in this process, which ensures that the movable plate 203 can remain fast and stable when moving without any deviation or shaking. As the movable plate 203 moves longitudinally, the intercepting plate 204 is also adjusted in the longitudinal position inside the receiving groove 102. This adjustment process enables the cross-sectional shielding area of ​​the intercepting plate 204 inside the slot 104 to be accurately adjusted, thereby achieving effective control of the aluminum liquid flow inside the guide groove 1.

[0040] like Figure 3 , Figure 4 As shown, the guide rod 207 runs through the movable plate 203 and is used to limit the moving position of the movable plate 203. The servo motor 205 is electrically connected to the external power supply through the controller. The guide rod 207 not only provides a stable moving trajectory for the movable plate 203, but also strictly limits its moving position, ensuring that the movable plate 203 can move quickly and accurately along a predetermined direction under the drive of the servo motor 205, effectively preventing the movable plate 203 from deflecting or shaking during the movement, thereby ensuring the accuracy and stability of the position adjustment of the shut-off plate 204. At the same time, the servo motor 205 is electrically connected to the external power supply through the controller, providing a reliable power source for the entire shut-off assembly 2. The controller can accurately control the start, stop and rotation speed of the servo motor 205, thereby realizing precise adjustment of the positions of the movable plate 203 and the shut-off plate 204.

[0041] like Figure 1 , Figure 2As shown, the guide trough 1 includes a guide trough body 101, a receiving groove 102 is formed on the inner side of the guide trough body 101, and a lining 103 is arranged inside, which ensures that the aluminum liquid can flow along a predetermined path. The receiving groove 102 formed on the inner side of the guide trough body 101 provides space for the installation of the lining 103. The setting of the lining 103 not only enhances the durability and corrosion resistance of the guide trough 1, but also can be replaced or repaired according to actual needs, thereby extending the service life of the guide trough 1. At the same time, the combined design of the receiving groove 102 and the lining 103 also makes the guide trough 1 have better adaptability and flexibility when dealing with aluminum liquids of different flow rates and temperatures. The lining 103 can be selected from different materials and thicknesses according to actual needs to meet the use requirements under different working conditions.

[0042] like Figure 1 , Figure 2 As shown, pressure plates 105 are bolted on both sides of the top of the guide trough main body 101, and one side of the bottom surface of the pressure plate 105 abuts against the top of the lining 103 to fix the position of the lining 103, ensuring that the lining 103 can be firmly installed in the accommodating groove 102. The pressure plate 105 is tightly connected to the guide trough main body 101 by bolts, and one side of the bottom surface abuts against the top of the lining 103, thereby effectively fixing the position of the lining 103 to prevent it from moving or shaking during the flow of aluminum liquid. At the same time, the design of the pressure plate 105 also enhances the overall structural strength of the guide trough 1. Since the pressure plate 105 and the guide trough main body 101 are connected by bolts, this connection method is not only firm and reliable, but also can disperse the pressure generated when the aluminum liquid flows, thereby reducing the deformation and wear of the guide trough main body 101.

[0043] like Figure 2 As shown, a liquid outlet 108 is provided at the lower side of the inner lining 103 at the very end, and the liquid outlet 108 penetrates the guide trough body 101 through the through opening, and is connected to the next processing process device in the outside world, ensuring that the aluminum liquid can flow out smoothly and accurately when it flows to the very end in the guide trough 1. The liquid outlet 108 is the end point of the flow of the aluminum liquid, and its position and size are carefully designed to ensure that the aluminum liquid can flow out evenly and stably to avoid turbulence or liquid accumulation. At the same time, the liquid outlet 108 penetrates the guide trough body 101 through the through opening, and is connected to the next processing process device in the outside world, realizing the seamless connection of the aluminum liquid from the guide trough 1 to the next processing process. After flowing out of the liquid outlet 108, the aluminum liquid can directly enter the next processing process device without additional transportation or processing, thereby greatly improving the production efficiency and the utilization rate of the aluminum liquid.

[0044] like Figure 6As shown, the two ends of the liner 103 are respectively provided with a plug-in block 106 and a plug-in groove 107, and the adjacent liners 103 are spliced ​​and connected through the plug-in block 106 and the plug-in groove 107, so that the adjacent liners 103 can be conveniently spliced ​​and connected through the plug-in block 106 and the plug-in groove 107. This connection method is not only simple and easy, but also firm and reliable, and can effectively ensure the continuity and sealing between the liners 103. During the aluminum liquid diversion process, the plug-in block 106 and the plug-in groove 107 are connected. The tight combination can prevent the leakage of molten aluminum, thereby ensuring the guiding effect of the guide groove 1 and the quality of the molten aluminum. At the same time, the splicing connection method of the plug-in block 106 and the plug-in groove 107 also makes the replacement and maintenance of the lining 103 more convenient. When a lining 103 needs to be replaced due to wear or damage, it is only necessary to disassemble the plug-in blocks 106 and the plug-in groove 107 at both ends, and then insert the new lining 103, without the need for large-scale disassembly and replacement of the entire guide groove 1.

[0045] like Figure 1 , Figure 2 As shown, a slot 104 is formed on the inner side of the liner 103 to provide a flow channel for the aluminum liquid, and the cross section of the slot 104 is a "U"-shaped structure as a whole. The intercepting plate 204 is adapted to the slot 104, ensuring that the aluminum liquid can flow stably and smoothly along a predetermined path, avoiding adverse phenomena such as turbulence and vortex that may occur in the flow process of the aluminum liquid, thereby improving the flow efficiency of the aluminum liquid and the guide effect of the guide groove 1. The cross section of the slot 104 is a "U"-shaped structure as a whole. This structural design not only enhances the structural strength of the slot 104, but also The aluminum liquid can be more evenly distributed in the entire slot 104 during the flow process, further improving the diversion stability and efficiency of the guide slot 1. At the same time, the matching design of the intercepting plate 204 and the slot 104 provides an effective means for controlling the flow rate of the aluminum liquid. The intercepting plate 204 can be inserted into or withdrawn from the slot 104 as needed, thereby changing the cross-sectional area of ​​the slot, and then adjusting the flow rate of the aluminum liquid. When the guide slot 1 faces aluminum liquid with different flow rates and flow rates, the best diversion effect can be achieved by adjusting the position of the intercepting plate 204.

[0046] Embodiment 2:

[0047] like Figure 3 , Figure 5As shown, the adjustment mechanism 3 includes a first screw rod 302 and a second screw rod 303. One end of the first screw rod 302 and the second screw rod 303 are rotatably connected to the movable plate 203 and the intercepting plate 204 respectively through the mounting ear 301. By twisting the threaded sleeve 304, the threaded connection characteristics of the threaded sleeve 304 and the first screw rod 302 and the second screw rod 303 at both ends can be used to accurately adjust the overall length of the threaded sleeve 304, the first screw 302 and the second screw 303, which provides a basis for adjusting the angle of the intercepting plate 204. With the rotation characteristics of the movable plate 203 and the intercepting plate 204, the angle of the intercepting plate 204 can be flexibly adjusted according to actual needs. At the same time, this adjustment method is not only fast but also efficient, and can respond promptly to the specific external use environment. Whether it is facing aluminum liquid with different flow rates or guide grooves 1 of different models, the angle of the intercepting plate 204 can be quickly adjusted by simply twisting the threaded sleeve to achieve the best interception effect.

[0048] like Figure 3 , Figure 5 As shown, the opposite ends of the first screw rod 302 and the second screw rod 303 are threadedly connected with a threaded sleeve 304, and the threaded sleeve 304 is threadedly connected to the first screw rod 302 and the second screw rod 303 in a mirror-image threaded connection. This connection method is not only simple and reliable, but also easy to operate. By rotating the threaded sleeve 304, the relative position between it and the first screw rod 302 and the second screw rod 303 can be accurately adjusted, thereby achieving fine adjustment of the length of the entire adjustment mechanism 3. At the same time, the threaded sleeve 304 is threadedly connected to the first screw rod 302 and the second screw rod 303 in a mirror-image threaded connection, which further enhances the flexibility and accuracy of the adjustment. The mirror-image threaded connection means that when the threaded sleeve 304 rotates, it can adjust the length of the first screw rod 302 and the second screw rod 303 simultaneously and equally, thereby maintaining the relative position between the movable plate 203 and the shut-off plate 204 stable.

[0049] like Figure 5 As shown, a hexagonal block 305 is fixedly provided on the outer side of the threaded sleeve 304 for providing a force point for an external tool to act on the threaded sleeve 304. When the threaded sleeve 304 needs to be rotationally adjusted, the presence of the hexagonal block 305 enables the operator to use a wrench or other appropriate tools to easily and accurately apply force, thereby achieving precise control of the threaded sleeve 304, which not only improves the convenience of adjustment, but also ensures stability and safety during the adjustment process. At the same time, the fixed setting of the hexagonal block 305 also enhances the overall structural strength of the threaded sleeve 304. Since the hexagonal block 305 is tightly connected to the threaded sleeve 304, it can provide additional support and stability for the threaded sleeve 304, thereby preventing deformation or damage caused by uneven or excessive force during the adjustment process.

[0050] During implementation, first, the liner 103 is placed into the receiving groove 102 formed on the inner side of the guide groove body 101. In this way, the multi-section guide groove 1 is spliced ​​end to end. At the same time, the adjacent liners 103 are spliced ​​end to end through the plug-in block 106 and the plug-in groove 107. After that, the pressure plate 105 is placed on the top of the guide groove body 101 and bolted to the guide groove body 101. At the same time, the pressure plate 105 abuts against the liner 103 on the bottom side to complete the installation operation of the multi-section guide groove 1. In this application, the guide groove 1 of the aluminum liquid can be set as a modular structure according to the above principle, and the guide groove 1 can be quickly assembled, which improves the convenience of installation and maintenance of the guide groove 1;

[0051] During the diversion process of aluminum liquid, the interception component 2 can be installed on the top of the guide groove 1 to be installed according to its use environment. As the aluminum liquid gradually flows, the servo motor 205 is started to drive the screw rod 206 to rotate, and the screw rod 206 is connected to the movable plate 203 by thread. At the same time, the movable plate 203 is quickly and stably adjusted in the longitudinal position through the guide rod 207. At the same time, the interception plate 204 is adjusted in the longitudinal position inside the receiving groove 102, so that the cross-sectional shielding area of ​​the interception plate 204 inside the slot 104 can be adjusted, and the interception effect at this stage can be changed, so as to realize the staged interception operation of the guide groove 1, avoid the splashing of aluminum liquid caused by the excessively fast flow speed of aluminum liquid in some stages, improve the protection against the outside world, and improve the transportation efficiency of aluminum liquid;

[0052] First, the threaded sleeve 304 is screwed, and the threaded connection between the threaded sleeve 304 and the first screw 302 and the second screw 303 at both ends is used to adjust the overall length of the threaded sleeve 304, the first screw 302, and the second screw 303, and the rotation characteristics of the movable plate 203 and the intercepting plate 204 are coordinated to adjust the angle of the intercepting plate 204. In this way, the angle of the intercepting plate 204 can be quickly adjusted according to the specific external use environment, thereby improving the adaptability of the intercepting plate 204 to aluminum liquids with different flow rates and guide grooves 1 of different models.

[0053] The advantages of this technical solution in practical applications include but are not limited to the following:

[0054] 1. The staged interception of aluminum liquid can be realized through the interception component, which can effectively avoid the splashing of aluminum liquid caused by the excessive flow speed of aluminum liquid in some stages, which not only improves the protection against the outside world, but also improves the transportation efficiency of aluminum liquid;

[0055] 2. The cutoff plate with an adjustment mechanism can adjust the angle according to actual needs, making the angle adjustment of the cutoff plate fast and efficient, and can quickly adapt to different external usage environments.
