Description

Technical Field

[0001] This invention belongs to the field of casting technology, specifically a high-flow-rate molten iron casting device and its casting method. Background Technology

[0002] Iron casting is one of the core processes in the casting industry. It refers to the precise pouring of molten iron (usually 1300-1550℃) into a pre-set mold cavity through a ladle. After the molten iron cools and solidifies, it forms blanks for various mechanical parts and structural components. The stability of this process directly determines the forming quality, dimensional accuracy, and production efficiency of the castings. It is widely used in key sectors of the national economy such as automobiles, construction machinery, machine tools, and rail transportation.

[0003] In the field of high-flow-rate molten iron casting, the characteristics of high molten iron flow rate and large fluid impact force have led to the core pain point of poor anti-splashing effect of traditional casting equipment. Traditional open casting lacks a dedicated flow guiding and anti-splashing structure. After high-flow-rate molten iron flows out of the ladle, it is easy to splash and overflow due to the deviation of the landing point and the fluid impact. This not only wastes molten iron raw materials, but may also cause safety accidents due to the splashing of high-temperature molten iron. Summary of the Invention

[0037] As a further preferred embodiment of this technical solution: a molten iron adding pipe is connected through the ladle, and a gate is provided on the top edge of the ladle, and a filter screen wall is detachably provided inside the ladle, located between the gate and the gate.

[0038] As a further preferred embodiment of this technical solution: a high-flow-rate molten iron casting method, comprising the following steps:

[0039] S1. Place each mold assembly into the positioning slot of the placement seat to complete the precise positioning of the mold, and zero and initialize the weighing element. Then, inject the preset amount of molten iron into the ladle through the molten iron addition pipe of the ladle.

[0040] S2. Drive the pouring unit on the moving track unit to move, wherein the roller slides along the inclined surface of the pressure block and applies pressure, driving the delivery pipe to move down and insert into the liquid inlet of the mold assembly until the locking component locks the connection seat, so that the delivery pipe is stabilized at the same height position, and the linkage auxiliary braking component controls the position where the pouring unit stops.

[0041] S3. The rotation drive component in the casting unit drives the ladle to tilt. After being filtered by the built-in filter screen wall, the molten iron flows out from the gate and falls into the long funnel. It is then injected into the mold at high speed through the delivery pipe inserted into the liquid inlet. The weighing element monitors the mold weight gain data in real time.

[0042] S4. When the weighing data reaches the preset value, the locking state of the connecting seat is released by the automatic unlocking component, the conveying pipe and the auxiliary brake component are reset, and then the angle of the ladle is reset.

[0043] S5. Drive the casting unit on the moving track unit to move to the next set of mold assemblies. Repeat steps S2-S4 to achieve continuous casting. After all molds are cast, reset the position of the casting unit, turn off the drive component, and disassemble the filter screen wall to clean the slag.

[0044] Compared with the prior art, the beneficial effects of the present invention are:

[0045] 1. In this invention, when the casting unit moves along the moving track to the target mold assembly, the rollers on the wheel frame will automatically slide along the inclined surface of the pressure block and apply downward pressure. The first connecting frame drives the conveying pipe to move down synchronously, and finally the lower end of the conveying pipe is inserted into the inner side of the mold inlet. With the long funnel and the long rectangular top opening design, it can completely cover the pouring point of high flow rate molten iron. Even if the molten iron flow rate is high, there is no need to manually adjust the relative position of the casting unit and the mold, blocking the path of molten iron splashing. Compared with the traditional open casting or fixed flow guiding structure, the anti-splashing effect is better, especially suitable for the continuous casting requirements under high flow rate conditions.

[0046] 2. In this invention, when the pressure block is pressed down, the connecting rod drives the corresponding rack to move through the second mounting block. The first gear drives the other rack to move upward, which precisely blocks the steel plate on the casting unit. With the signal linkage between the position detection sensor and the sensor receiving element, the casting unit can be accurately stopped at the designated position under the drive of the moving track unit, ensuring the alignment accuracy between the delivery pipe and the mold inlet, and avoiding insertion deviation due to inertial displacement.

[0047] 3. In this invention, as the conveying pipe is inserted into the liquid inlet, the connecting seat moves down with the pressure block and is fitted onto the outside of the insertion seat. The edge of the slot squeezes the limiting block to shrink. After the limiting block is aligned with the limiting groove, the second reset spring pushes the limiting block into the limiting groove, thereby automatically locking the connecting seat. This ensures that the conveying pipe remains in the inserted state under the impact of high-flow-rate molten iron and will not be displaced or shaken.

[0048] 4. In this invention, when the amount of molten iron poured reaches the specified value, the signal is fed back to the controller, which drives the electric push rod to push the push plate to push the limit block out of the limit groove. Under the action of the first reset spring, the connecting seat drives the conveying pipe to automatically reset, and the stop block moves down synchronously to release the obstruction to the steel plate. The pouring unit can move directly along the moving track to the next mold assembly. The whole process does not require manual unlocking or switching of workstations. Attached Figure Description

Detailed Implementation

[0059] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0060] Please see Figures 1-9 This application provides a high-flow-rate molten iron pouring device, including a base plate 100, on which a movable track unit 200 is provided. It should be noted that the movable track unit 200 is existing technology, including a slide rail and a slider 4053 mounted on the slide rail, and a drive unit for driving the slider 4053 to move on the slide rail. The slide rail is mounted on the base plate 100, and a pouring unit 500 is mounted above the slider 4053 to enable movement of the pouring unit 500, thereby sequentially pouring molten iron into the mold assembly 700. The movable track unit 200 is equipped with a casting unit 500, and the base plate 100 is provided with several mold assemblies 700. Each mold assembly 700 has a liquid inlet 701 at its top, through which molten iron is poured into the mold assembly 700 to achieve the purpose of casting. The base plate 100 is also equipped with a riser frame 600, located between the mold assembly 700 and the casting unit 500. The riser frame 600 is equipped with several sets of anti-spill units 400, and each set of anti-spill units 400 is used in conjunction with a corresponding mold assembly 700.

[0061] Each anti-splash unit 400 includes an L-shaped bracket 401 mounted on the riser 600. An automatic drop hole assembly 402 is installed on the L-shaped bracket 401. The automatic drop hole assembly 402 includes a conveying pipe 4022 slidably mounted on the L-shaped bracket 401. A long funnel 4023 is connected through the upper end of the conveying pipe 4022. The top opening of the long funnel 4023 is a long rectangle that can encompass the drop point of molten iron in the casting unit 500. A spring seat 4021 is also provided on the outer wall of the conveying pipe 4022. The spring seat 4021 is connected to a pressure block 4026 through a first connecting frame 4025. The pressure block 4026 is a right trapezoid. It should be noted that the corner where the top surface of the pressure block 4026 connects to the inclined surface is rounded to ensure the smoothness of the movement of the wheel frame 508 on the pressure block 4026.

[0062] The anti-spray unit 400 also includes a connecting seat 403 and a locking assembly 405. The connecting seat 403 is disposed on the side wall of the pressure block 4026, while the locking assembly 405 is disposed on the riser 600 and located below the connecting seat 403, for locking the connecting seat 403.

[0063] The casting unit 500 includes a second base 501 disposed on the moving track unit 200. A fixing frame 507 is mounted on the second base 501. A wheel frame 508 is disposed on the end of the fixing frame 507 away from the second base 501. A roller 509 for pressing the pressure block 4026 is rotatably disposed on the wheel frame 508.

[0064] Specifically, the casting unit 500 can move linearly along the moving track unit 200. Before the casting unit 500 moves sequentially to align with the mold assembly 700 to be cast, the second base 501 drives the fixed frame 507 to move. The fixed frame 507 drives the rollers 509 on the wheel frame 508 to move. The rollers 509 first move to the inclined surface of the pressure block 4026, and the height of the rollers 509 is fixed. Therefore, a downward pressing force is applied to the pressure block 4026. The pressure block 4026 drives the spring seat 4021 to move downward through the first connecting frame 4025. When it reaches the lowest point, the lower end of the delivery pipe 4022 inserts into the inside of the liquid inlet 701, preventing iron from entering the container. As water is poured into the inlet 701 from the delivery pipe 4022, molten iron splashes out. During this process, the pressure block 4026 simultaneously drives the connecting seat 403 to move downwards. When the wheel frame 508 moves to the top surface of the pressure block 4026, it can stabilize the height of the pressure block 4026. At this time, the locking component 405 locks the connecting seat 403, that is, the height of the pressure block 4026 is fixed, ensuring the stability of the automatic drop hole component 402 during the process of the lower end of the delivery pipe 4022 being inserted into the inlet 701. Afterwards, during the process of the casting unit 500 rotating and pouring out the molten iron, the long funnel 4023 can completely catch the molten iron without adjusting the positions of the two. It only ensures that during the high-flow-rate casting process, the molten iron will not be poured onto the outside of the inlet 701.

[0065] Furthermore, the anti-spill unit 400 also includes an auxiliary braking assembly 404, which includes a connecting rod 4041, a stop block 4047, and a bearing seat 4042. The connecting rod 4041 is disposed on the bottom surface of the pressure block 4026, and the riser 600 has a second sliding groove for the connecting rod 4041 to slide. The stop block 4047 is arranged parallel to the connecting rod 4041, and the riser 600 has a first sliding groove 601 for the stop block 4047 to slide. Shaft 4043 is mounted on the bottom surface of riser 600. A first rotating shaft 4043 is rotatably mounted on the side of shaft seat 4042. A first gear 4044 is mounted on the first rotating shaft 4043. A first rack 4045 is meshed on both sides of the first gear 4044. One rack 4045 is fixedly connected to the connecting rod 4041 through a second mounting block 4048. The other rack 4045 is fixedly connected to the stop block 4047 through a first mounting block 4046.

[0066] The second base 501 is also equipped with a steel plate 510 that works in conjunction with the stop block 4047. It should be noted that both the steel plate 510 and the stop block 4047 are preferably made of high-strength aluminum alloy, which has the characteristics of being lightweight and strong.

[0067] Specifically, when the first connecting frame 4025 is pressed down, the first connecting frame 4025 drives the connecting rod 4041 to move downward. The connecting rod 4041 drives the first rack 4045 connected to it to move downward through the second mounting block 4048. The first gear 4044 on the first rotating shaft 4043 rotates, and then the other first rack 4045 is driven to move upward. It pushes the stop block 4047 to move upward relative to the heightening frame 600 through the first mounting block 4046. This can block the movement trajectory of the steel plate 510 and help the pouring unit 500 to move to the designated position by the moving track unit 200. This avoids the problem that the pouring unit 500 cannot stop when it reaches the designated position due to inertia, thus ensuring that the pouring point is always within the receiving range of the long funnel 4023.

[0068] Furthermore, the automatic hole-dropping assembly 402 also includes a first reset spring 4024 sleeved outside the conveying pipe 4022, located between the L-shaped bracket 401 and the spring seat 4021, which plays a reset role and can be reset by utilizing the elastic potential energy of the conveying pipe 4022 after the locking assembly 405 releases the locking of the connecting seat 403.

[0069] Furthermore, the locking assembly 405 includes an insertion seat 4051, a second rotating shaft 4057, a guide shaft 4054, and a second return spring 4056.

[0070] Insertion seat 4051 is mounted on the riser 600. Two symmetrically arranged limiting blocks 4052 are slidably mounted on insertion seat 4051. Each limiting block 4052 has a slider 4053 on its bottom surface. It should be noted that the limiting block 4052 is trapezoidal, and the top surface of the limiting block 4052 is completely located inside the insertion seat 4051. The inclined surface of the bearing seat 4042 is located outside the insertion seat 4051.

[0071] The second rotating shaft 4057 is set on the inner wall of the insertion seat 4051. The second rotating shaft 4057 is rotatably mounted with a second gear 4058. A second rack 4059 is meshed with each side of the second gear 4058, and each second rack 4059 is fixedly connected to a limiting block 4052.

[0072] Two guide shafts 4054 are provided and are fixedly connected to the inside of the insertion seat 4051 and arranged in parallel. Both sliders 4053 are slidably mounted on the guide shafts 4054.

[0073] The second return spring 4056 is sleeved on the outside of the guide shaft 4054, and the guide shaft 4054 is provided with a limit plate 4055. The second return spring 4056 is located between the limit plate 4055 and the limit block 4052. It should be noted that the guide shaft 4054 can play a role in limiting and guiding the movement of the limit block 4052, and the first mounting block 4046 allows the limit block 4052 to reset under the action of its elastic potential energy after being pressed inside the insertion seat 4051.

[0074] The bottom surface of the connector 403 is provided with a slot 4031 that is compatible with the insert 4051. The top of the slot 4031 is provided with a limiting groove 4032 for locking the limiting block 4052.

[0075] Specifically, during the process of the pressure block 4026 being pressed down and moving downward, the connecting seat 403 moves downward along with it. The downward movement of the connecting seat 403 causes the slot 4031 to fit onto the insertion seat 4051. Under the squeezing action of the edge wall of the slot 4031, the limiting block 4052 is pushed to retract towards the inside of the insertion seat 4051. During this process, the slider 4053 slides on the guide shaft 4054, while the second return spring 4056 is compressed until the limiting block 4052 is aligned with the limiting groove 4032. Under the action of the elastic force of the second return spring 4056, the two limiting blocks 4052 are pushed into the inside of the limiting groove 4032 and are locked, thereby locking the connecting seat 403.

[0076] Furthermore, the base plate 100 is also provided with the same number of placement units 300 as the mold assemblies 700, and each placement unit 300 is used to place one mold assembly 700. The placement unit 300 includes a weighing pan 301, which is fixedly installed on the top surface of the base plate 100. A weighing element 302 is provided on the weighing pan 301, and a placement seat 303 is provided above the weighing element 302. A positioning groove 304 is provided on the placement seat 303 for placing the mold assembly 700. It should be noted that the positioning groove 304 is the same size and shape, which can place the mold assembly 700 on the placement seat 303 in the designated position, without the need to repeatedly adjust the position of the mold assembly 700.

[0077] Furthermore, the connecting base 403 is also provided with an automatic unlocking component 407, wherein the automatic unlocking component 407 includes a first base 4071, the first base 4071 is disposed on the top surface of the connecting base 403, the first base 4071 is provided with an electric push rod 4072, the output end of the electric push rod 4072 is provided with a connecting plate 4073, the connecting plate 4073 is connected to a push plate 4075 through a second connecting frame 4074, and the connecting base 403 is provided with a movable groove 4033 for the push plate 4075 to move, and the movable groove 4033 is connected to the limiting groove 4032.

[0078] The electric push rod 4072 is equipped with a controller, and the controller, the electric push rod 4072 and the weighing element 302 are connected by electrical signals.

[0079] Specifically, the weighing element 302 can measure the weight increase of the mold assembly 700 due to the pouring of molten iron, and when the weight reaches a specified value, it can transmit a signal to the controller. The controller controls the electric push rod 4072 to retract and extend a full stroke. During the retraction process, it drives the connecting plate 4073 to move. The connecting plate 4073 drives the push plate 4075 to push a limit block 4052 to move through the second connecting frame 4074. And through the transmission action of the second rotating shaft 4057, the second gear 4058 and the second rack 4059, Next, another limiting block 4052 moves in the opposite direction to the other limiting block 4052 until the two limiting blocks 4052 disengage from the limiting groove 4032. Under the action of the first reset spring 4024, the connecting seat 403 is pushed upward, thereby unlocking the connecting seat 403. This allows the stop block 4047 to reset downward, removing the obstruction to the movement of the steel plate 510. As a result, the casting unit 500 can continue to move on the moving track unit 200 to cast the next mold assembly 700 without manual unlocking.

[0080] Furthermore, a sensor receiving element 511 is also provided on the second base 501, and a position detection sensor 406 is provided on the side wall of the connecting seat 403 to be used in conjunction with the sensor receiving element 511. The sensor receiving element 511, the position detection sensor 406 and the moving track unit 200 are electrically connected. When the position detection sensor 406 is aligned with the sensor receiving element 511, the moving track unit 200 can be controlled to continue running. The stop block 4047 and the steel plate 510 are provided to avoid the problem of inaccurate movement of the casting unit 500 due to signal extension.

[0081] Furthermore, the casting unit 500 also includes a mounting frame 502 and a rotation drive assembly. The mounting frame 502 is mounted on the second base 501. A third rotating shaft 503 is rotatably mounted on the mounting frame 502. A mounting seat 504 is mounted on the third rotating shaft 503. A ladle 505 is fixedly mounted on the mounting seat 504 for storing molten iron.

[0082] The rotation drive assembly includes a servo motor mounted on the mounting bracket 502, and the output end of the servo motor is connected to the third rotating shaft 503 for driving the third rotating shaft 503 to rotate.

[0083] Specifically, the rotating component drives the third rotating shaft 503 to rotate, and the third rotating shaft 503 drives the ladle 505 on the mounting base 504 to rotate and tilt, pouring molten iron into the mold assembly 700.

[0084] Furthermore, a molten iron adding pipe 5052 is connected through the ladle 505, and a gate 5051 is provided on the top edge of the ladle 505. A filter screen wall 506 is detachably installed inside the ladle 505 to intercept slag in the molten iron. It is located between the gate 5051 and the gate 5052. The molten iron adding pipe 5052 is used to inject molten iron into the interior of the ladle 505. During this process, the molten iron does not pass through the filter screen wall 506. When the rotating component drives the ladle 505 to rotate, the molten iron first passes through the filter screen wall 506 and then flows out from the gate 5051, which can prevent slag from being poured into the interior of the mold assembly 700.

[0085] Furthermore, an adjustment component 408 is provided below the conveying pipe 4022. The adjustment component 408 includes an extension sleeve 4081 that is slidably disposed on the outside of the conveying pipe 4022. A bolt groove 4082 is provided on the extension sleeve 4081. A bolt 4083 is provided inside the bolt groove 4082 to limit the position of the extension sleeve 4081. The friction of the end of the bolt 4083 abuts against the outer wall of the conveying pipe 4022, thereby realizing the adjustment of the length of the conveying pipe to accommodate mold assemblies 700 of different heights.

[0086] A method for casting molten iron at high flow rates includes the following steps:

[0087] S1. Place each mold assembly 700 into the positioning slot 304 of the placement seat 303 to complete the precise positioning of the mold, and reset the weighing element 302 to zero. Then, inject the preset amount of molten iron into the ladle 505 through the molten iron adding pipe 5052 of the ladle 505.

[0088] S2. Move the casting unit 500 on the drive track unit 200. Roller 509 slides along the inclined surface of pressure block 4026 and applies pressure, causing the delivery pipe 4022 to move down and insert into the liquid inlet 701 of mold assembly 700 until the locking component 405 is triggered to lock the connecting seat 403, so that the delivery pipe 4022 is stabilized at the same height position, and the auxiliary braking component 404 is linked to control the stopping position of the casting unit 500.

[0089] S3. The rotation drive assembly in the casting unit 500 drives the ladle 505 to tilt. After being filtered by the built-in filter screen wall 506, the molten iron flows out from the gate 5051 and falls into the long funnel 4023. It is then injected into the mold at high speed through the delivery pipe 4022 inserted into the liquid inlet 701. The weighing element 302 monitors the mold weight gain data in real time.

[0090] S4. When the weighing data reaches the preset value, the locking state of the connecting seat 403 is released by the automatic unlocking component 407, the conveying pipe 4022 and the auxiliary braking component 404 are reset, and then the angle of the ladle 505 is reset.

[0091] S5. Drive the casting unit 500 on the moving track unit 200 to move to the next set of mold assemblies 700. Repeat steps S2-S4 to achieve continuous casting. After all molds are cast, reset the position of the casting unit 500, turn off the driving component, and disassemble the filter screen wall 506 to clean the slag.
