Description

Technical Field

[0001] This invention relates to the field of cast iron casting technology, specifically a cast iron casting device for a shell with intelligent cooling function. Background Technology

[0002] Cast iron, as an important metallic material, is widely used in many fields such as machinery manufacturing, automotive industry, and construction engineering due to its excellent casting performance, shock absorption performance, and wear resistance. Shell castings, as a crucial component of cast iron products, directly affect the performance and reliability of related equipment. During the casting process of shell-type cast iron, uniform stirring, slag removal, and cooling control are key factors affecting casting quality; however, existing technologies still have many shortcomings in these aspects.

[0003] Before casting iron, the molten iron needs to be stirred to ensure that its various components are evenly distributed, guaranteeing consistency in chemical composition and microstructure, thereby improving the quality stability of the casting. Currently, traditional stirring methods mainly rely on manual stirring or simple mechanical stirring devices.

[0004] Manual stirring is not only labor-intensive and inefficient, but also makes it difficult to guarantee the uniformity of stirring, and is easily affected by the operator's skill level and physical condition. Although simple mechanical stirring devices improve stirring efficiency to some extent, the stirring method is relatively simple, usually only achieving stirring by rotating the stirring paddle, which is difficult to achieve all-round and multi-level stirring of molten iron.

[0005] During the smelting and transportation of molten iron, impurities such as slag and iron oxide inevitably mix in. If these impurities are not removed in time, they will form inclusion defects in the castings, reducing the mechanical properties and surface quality of the castings, and in severe cases, even causing the castings to be scrapped. Therefore, slag removal is an essential step in the cast iron casting process.

[0006] The cooling process has a crucial impact on the microstructure and properties of castings. A reasonable cooling rate can result in an ideal microstructure, thereby improving the mechanical properties and dimensional accuracy of the casting. However, traditional cast iron casting equipment suffers from numerous problems in cooling control. Summary of the Invention

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. In this invention, after molten iron enters the outer cylinder, the controller controls the motor to periodically rotate in both forward and reverse directions, driving the driving gear and driven gear to rotate. This causes the driven gear to revolve around the gear ring and rotate on its own axis. The main rod drives the stirring plate to stir the molten iron, while the secondary rod revolves and rises and falls with the driven gear, pushing the slider to rotate synchronously. When the motor rotates forward, the first and second electric push rods extend, and the secondary rod drives the inner and outer rotating plates to rotate and rise, pushing the upper outer rotating plate to rotate in the opposite direction to the inner rotating plate. Through the transmission of the first and second straight columns, the lower outer rotating plate rotates synchronously with the inner rotating plate. When the motor rotates in reverse, the first and second electric push rods retract, and the outer and inner rotating plates rotate downwards and in the opposite direction, forming a complex vortex, which improves the uniformity of the molten iron.

[0021] 2. During slag removal, the outer cylinder is left to stand still, allowing impurities to float to the surface. The first and second electric push rods drive the outer and inner rotating plates to rotate and maintain a horizontal position, forming a lifting plate with the circular plate. The motor and the cover are lifted by the external lifting assembly, which drives the slag to be discharged.

[0022] 3. In this invention, the double-headed spring electric telescopic rod in the shaking unit pushes the counterweight ball to roll on the annular groove of the mounting plate, causing the shaking ball to rotate within the support ring. The mounting plate alternates between high and low. The lower side pulls the pressure rod to move the support plate down, while the higher side pushes the pressure rod to compress the reset spring and lift the support plate, causing the outer cylinder to tilt and swing. This, combined with the rotating ball and the arc plate, creates a left-right swaying motion, enhancing the complexity of the molten iron flow field and improving the mixing efficiency.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0037] Example: Figures 1-12 As shown, the present invention provides a technical solution:

[0038] like Figure 1 As shown, a cast iron casting device for a shell with intelligent cooling function includes a mounting frame 1, a slag removal unit 2, a shaking unit 3, a cooling unit 4, and a discharge unit 5. The mounting frame 1 is placed on a horizontal ground. The slag removal unit 2 is fixedly connected to the shaking unit 3. The slag removal unit 2 has the functions of removing slag and stirring molten iron. The shaking unit 3 is fixedly connected to the mounting frame 1, the shaking unit 3 is fixedly connected to the cooling unit 4, the shaking unit 3 is fixedly connected to the discharge unit 5, the cooling unit 4 is fixedly connected to the mounting frame 1, and the discharge unit 5 is fixedly connected to the mounting frame 1.

[0039] Mounting frame 1 is used to mount and fix slag removal unit 2, shaking unit 3, cooling unit 4 and discharge unit 5. Slag removal unit 2 is used to remove slag from molten iron and stir the molten iron. Shaking unit 3 is used to improve the uniformity of molten iron. Cooling unit 4 is used for intelligent cooling of molten iron. Discharge unit 5 is used for discharging molten iron. After the molten iron enters the shaking unit 3, the shaking unit 3 and slag removal unit 2 work together to stir the molten iron evenly, reduce the non-uniformity of molten iron at different levels, and improve the uniformity of molten iron. At the same time, the cooling unit 4 is used to cool the overheated molten iron. After the molten iron is stirred, the slag attached to the surface is removed by the slag removal unit 2 to improve the purity of molten iron. The uniform and high-purity molten iron is discharged to the next process by the discharge unit 5.

[0040] like Figure 3 , Figures 6-8 As shown, the slag removal unit 2 includes a motor 21, a driving gear 22, a driven gear 23, a main rod 24, and a secondary rod 25. The output end of the motor 21 is fixedly connected to the driving gear 22. The driving gear 22 is meshed with the driven gear 23. The driving gear 22 is fixedly connected to the main rod 24. The driven gear 23 is fixedly connected to the secondary rod 25. The driven gear 23 is threadedly connected to the secondary rod 25.

[0041] like Figure 3 , Figures 6-8 As shown, the slag removal unit 2 also includes a stirring plate 26, a slider 27, a first electric push rod 28, an outer rotating plate 29, an inner rotating plate 210, and a second electric push rod 211. The main rod 24 is fixedly connected to the stirring plate 26, and the slider 27 is slidably connected to the secondary rod 25. The fixed end of the first electric push rod 28 is fixedly installed on the slider 27. There are two sets of outer rotating plates 29 and inner rotating plates 210. The output end of the first electric push rod 28 passes through the slider 27 and is fixedly connected to the outer rotating plate 29 located above. The fixed end of the second electric push rod 211 is fixedly installed on the slider 27, and the output end of the second electric push rod 211 passes through the slider 27 and is fixedly connected to the inner rotating plate 210 located above. The outer rotating plate 29 is rotatably installed on the secondary rod 25, and the inner rotating plate 210 is rotatably installed on the secondary rod 25.

[0042] like Figure 6 , Figure 7As shown, the slag removal unit 2 also includes a cover 212, a toothed ring 213, a circular plate 214, a first straight column 215 and a second straight column 216. A slider 27 is slidably mounted on the cover 212. A motor 21 is fixedly mounted on the cover 212. The toothed ring 213 is meshed with the driven gear 23 and is fixedly mounted on the cover 212. The circular plate 214 is fixedly mounted on the main rod 24. Both ends of the first straight column 215 are fixedly connected to the outer rotating plate 29. Both ends of the second straight column 216 are fixedly connected to the inner rotating plate 210. The first straight column 215 and the second straight column 216 are symmetrically arranged with the secondary rod 25 as the center. The first electric push rod 28 is coaxially arranged with the first straight column 215, and the second electric push rod 211 is coaxially arranged with the second straight column 216.

[0043] After the molten iron enters the outer cylinder 31, the controller 11 starts the motor 21, causing it to periodically rotate in both directions. This drives the drive gear 22 to rotate, causing the driven gear 23, which meshes with it, to revolve around the gear ring 213 while simultaneously rotating on its own axis. The rotation of the drive gear 22 also drives the main rod 24 to rotate, causing the stirring plate 26 to uniformly stir the molten iron inside the outer cylinder 31, improving its uniformity. During the rotation of the driven gear 23, the secondary rod 25 rotates and moves up and down. As the secondary rod 25 revolves around the driven gear 23, it pushes the slider 27 to rotate synchronously. Simultaneously, while the controller 11 controls the motor 21 to drive the drive gear 22 to rotate forward, the controller 11 also controls the first electric push rod 28 and the second electric push rod 211 to extend. As the secondary rod 25 drives the inner rotating plate 210 and the outer rotating plate 29 to rotate and rise, it respectively pushes the upper outer rotating plate 29 and the inner rotating plate 210. The rotating plate 210 rotates in opposite directions. Under the transmission action of the first straight column 215 and the second straight column 216, the lower inner rotating plate 210 and the outer rotating plate 29 rotate synchronously. While the controller 11 controls the motor 21 to drive the drive gear 22 to rotate in the opposite direction, the controller 11 controls the first electric push rod 28 and the second electric push rod 211 to start retraction. During the process of the secondary rod 25 driving the inner rotating plate 210 and the outer rotating plate 29 to rotate and descend, the upper outer rotating plate 29 and the inner rotating plate 210 are respectively pulled to rotate in opposite directions. Under the transmission action of the first straight column 215 and the second straight column 216, the lower inner rotating plate 210 and the outer rotating plate 29 rotate synchronously. Under the periodic forward and reverse rotation of the motor 21, the molten iron in the outer cylinder 31 forms a more complex vortex state, which increases the mixing uniformity of the molten iron. At the same time, it breaks the state of molten iron with different uniformity in the upper and lower layers in the outer cylinder 31, providing good conditions for uniform mixing of molten iron.

[0044] After the molten iron is evenly mixed, the outer cylinder 31 is allowed to stand for a period of time, allowing impurities in the molten iron to float to the surface. Then, the first electric push rod 28 and the second electric push rod 211 push the outer rotating plate 29 and the inner rotating plate 210 to rotate slowly until they are horizontal. At this time, the outer rotating plate 29 and the inner rotating plate 210, together with the circular plate 214, form a horizontal lifting plate. The motor 21 and the cover 212 are lifted upward synchronously by the external lifting assembly (the lifting assembly is existing technology and can be a crane, electric hoist, etc., which will not be described in detail here). As the outer rotating plate 29, the inner rotating plate 210 and the circular plate 214 rise upward, the slag floating on the surface of the molten iron is carried out of the outer cylinder 31, thereby realizing the slag removal action of the molten iron and avoiding the slag impurities from affecting the quality of subsequent castings.

[0045] like Figure 4 , Figure 11 , Figure 12 As shown, the shaking unit 3 includes an outer cylinder 31, an arc plate 32, a spring cylinder 33, a rotating ball 34, and a support plate 35. The outer cylinder 31 is provided with a discharge port, and a temperature sensor is provided on the outer wall of the outer cylinder 31. The outer cylinder 31 is fixedly connected to the arc plate 32, and the arc plate 32 is fixedly connected to one end of the spring cylinder 33. The other end of the spring cylinder 33 is rotatably connected to the rotating ball 34. The rotating ball 34 is rotatably connected to the mounting frame 1, and the support plate 35 abuts against the bottom of the outer cylinder 31.

[0046] like Figure 4 , Figure 5 As shown, the rocking unit 3 also includes a fixed ring 36, a return spring 37, a straight rod 38, a bent rod 39, and a support ring 310. The fixed ring 36 is fixedly connected to one end of the return spring 37, both ends of the straight rod 38 are fixedly connected to the fixed ring 36, the fixed ring 36 is fixedly connected to one end of the bent rod 39, the other end of the bent rod 39 is fixedly connected to the mounting bracket 1, and the support ring 310 is fixedly connected to the bent rod 39 through a connecting rod.

[0047] like Figure 2 , Figure 4 , Figure 5 As shown, the shaking unit 3 also includes a shaking ball 311, a mounting plate 312, a counterweight ball 313, a double-headed spring electric telescopic rod 314, a push plate 315, and a pressure rod 316. The shaking ball 311 is fixedly connected to the mounting plate 312, and the mounting plate 312 is fixedly connected to the other end of the return spring 37. An annular groove is provided on the mounting plate 312, and the counterweight ball 313 is placed in the annular groove of the mounting plate 312. The fixed end of the double-headed spring electric telescopic rod 314 is fixedly installed in the annular groove of the mounting plate 312. The push plate 315 is fixedly connected to the telescopic ends of the double-headed spring electric telescopic rod 314. One end of the pressure rod 316 is fixedly connected to the mounting plate 312, and the other end of the pressure rod 316 is fixedly connected to the support plate 35. The pressure rod 316 is slidably connected to the fixed ring 36.

[0048] While the molten iron is being stirred, the controller 11 controls the motor 21 to rotate in both directions and simultaneously activates the double-headed spring-loaded electric telescopic rod 314. This causes the push plate 315 to push the counterweight ball 313 to roll in the annular groove of the mounting plate 312. As the counterweight ball 313 rolls, the mounting plate 312 causes the swaying ball 311 to rotate within the support ring 310, keeping the mounting plate 312 in a state where one side is lower than the other. The lower side pulls the pressure rod 316, causing the support plate 35 to move downwards and not contact the outer cylinder 31. The higher side pushes the pressure rod 316 to compress the return spring 37. Simultaneously, the movement upward along the fixed ring 36 drives the support plate 35 to lift the outer cylinder 31 upward, thus causing the outer cylinder 31 to tilt and swing. When the outer cylinder 31 tilts, the tilted end squeezes the arc plate 32 and the spring cylinder 33, causing the rotating ball 34 to rotate on the mounting frame 1. During the clockwise and counterclockwise sliding of the counterweight ball 313, the outer cylinder 31 forms a left-right swaying motion, making the molten iron inside the outer cylinder 31 form a more complex flow field. Together with the slag removal unit 2, it improves the mixing uniformity of the molten iron, makes the molten iron quickly reach uniformity, and improves working efficiency.

[0049] like Figure 2 , Figure 11 As shown, the cooling unit 4 includes a water tank 41 and a spiral cooling pipe 42. The water tank 41 is fixedly installed on the mounting bracket 1, and the spiral cooling pipe 42 is fixedly installed on the outer wall of the outer cylinder 31. Both ends of the spiral cooling pipe 42 are connected to the water tank 41. A condenser is installed inside the water tank 41, and a water pump is installed inside the water tank 41.

[0050] When the temperature sensor on the outer wall of the outer cylinder 31 detects that the temperature of the outer cylinder 31 exceeds the preset value, the controller 11 controls the water pump in the water tank 41 to introduce cold water into the inlet of the spiral cooling pipe 42. The cold water cools the outer cylinder 31 through the spiral cooling pipe 42, and the outer cylinder 31 cools the molten iron, realizing the intelligent cooling function of the molten iron. The cooling water carrying heat flows back into the water tank 41 for cooling.

[0051] like Figure 8 , Figure 10 As shown, the discharge unit 5 includes a hydraulic push rod 51, a guide channel 52, a stop block 53, and a buffer spring 54. The fixed end of the hydraulic push rod 51 is fixedly installed on the mounting bracket 1. The output end of the hydraulic push rod 51 is fixedly connected to the end of the guide channel 52 away from the outer cylinder 31. The end of the guide channel 52 near the discharge port of the outer cylinder 31 abuts against the stop block 53. The stop block 53 is slidably installed at the discharge port of the outer cylinder 31. One end of the buffer spring 54 is fixedly connected to the stop block 53, and the other end of the buffer spring 54 is fixedly connected to the inner surface of the outer cylinder 31 near the horizontal ground.

[0052] After the slag removal and uniform mixing of the molten iron are completed, the hydraulic push rod 51 is extended by the controller 11, which pushes the guide groove 52 to rotate. The guide groove 52 squeezes the stop block 53 to move downward and compresses the buffer spring 54 to open the discharge port of the outer cylinder 31. The molten iron in the outer cylinder 31 is transported to the mold through the discharge port and the guide groove 52, thereby realizing the discharge.

[0053] like Figure 10 As shown, a controller 11 is installed on the mounting bracket 1.

[0054] In order to achieve automation and timely response of the device, save manpower and make the device work more smoothly, the controller 11 can autonomously deal with emergencies, making it easier to detect and deal with problems in a timely manner.

[0055] Working principle of the invention:

[0056] After the molten iron enters the outer cylinder 31, the controller 11 starts the motor 21, causing it to periodically rotate in both directions. This drives the drive gear 22 to rotate, causing the driven gear 23, which meshes with it, to revolve around the gear ring 213 while simultaneously rotating on its own axis. The rotation of the drive gear 22 also drives the main rod 24 to rotate, causing the stirring plate 26 to uniformly stir the molten iron inside the outer cylinder 31, improving its uniformity. During the rotation of the driven gear 23, the secondary rod 25 rotates and moves up and down. As the secondary rod 25 revolves around the driven gear 23, it pushes the slider 27 to rotate synchronously. Simultaneously, while the controller 11 controls the motor 21 to drive the drive gear 22 to rotate forward, the controller 11 also controls the first electric push rod 28 and the second electric push rod 211 to extend. As the secondary rod 25 drives the inner rotating plate 210 and the outer rotating plate 29 to rotate and rise, it respectively pushes the upper outer rotating plate 29 and the inner rotating plate 210. The rotating plate 210 rotates in opposite directions. Under the transmission action of the first straight column 215 and the second straight column 216, the lower inner rotating plate 210 and the outer rotating plate 29 rotate synchronously. While the controller 11 controls the motor 21 to drive the drive gear 22 to rotate in the opposite direction, the controller 11 controls the first electric push rod 28 and the second electric push rod 211 to start retraction. During the process of the secondary rod 25 driving the inner rotating plate 210 and the outer rotating plate 29 to rotate and descend, the upper outer rotating plate 29 and the inner rotating plate 210 are respectively pulled to rotate in opposite directions. Under the transmission action of the first straight column 215 and the second straight column 216, the lower inner rotating plate 210 and the outer rotating plate 29 rotate synchronously. Under the periodic forward and reverse rotation of the motor 21, the molten iron in the outer cylinder 31 forms a more complex vortex state, which increases the mixing uniformity of the molten iron. At the same time, it breaks the state of molten iron with different uniformity in the upper and lower layers in the outer cylinder 31, providing good conditions for uniform mixing of molten iron.

[0057] After the molten iron is evenly mixed, the outer cylinder 31 is allowed to stand for a period of time, allowing impurities in the molten iron to float to the surface. Then, the first electric push rod 28 and the second electric push rod 211 push the outer rotating plate 29 and the inner rotating plate 210 to rotate slowly until they are horizontal. At this time, the outer rotating plate 29 and the inner rotating plate 210, together with the circular plate 214, form a horizontal lifting plate. The motor 21 and the cover 212 are lifted upward synchronously by the external lifting components. As the outer rotating plate 29, the inner rotating plate 210 and the circular plate 214 rise upward, the slag floating on the surface of the molten iron is carried out of the outer cylinder 31, thereby realizing the slag removal action of the molten iron and avoiding the impact of slag impurities on the quality of subsequent castings.

[0058] While the molten iron is being stirred, the controller 11 controls the motor 21 to rotate in both directions and simultaneously activates the double-headed spring-loaded electric telescopic rod 314. This causes the push plate 315 to push the counterweight ball 313 to roll in the annular groove of the mounting plate 312. As the counterweight ball 313 rolls, the mounting plate 312 causes the swaying ball 311 to rotate within the support ring 310, keeping the mounting plate 312 in a state where one side is lower than the other. The lower side pulls the pressure rod 316, causing the support plate 35 to move downwards and not contact the outer cylinder 31. The higher side pushes the pressure rod 316 to compress the return spring 37. Simultaneously, the movement upward along the fixed ring 36 drives the support plate 35 to lift the outer cylinder 31 upward, thus causing the outer cylinder 31 to tilt and swing. When the outer cylinder 31 tilts, the tilted end squeezes the arc plate 32 and the spring cylinder 33, causing the rotating ball 34 to rotate on the mounting frame 1. During the clockwise and counterclockwise sliding of the counterweight ball 313, the outer cylinder 31 forms a left-right swaying motion, making the molten iron inside the outer cylinder 31 form a more complex flow field. Together with the slag removal unit 2, it improves the mixing uniformity of the molten iron, makes the molten iron quickly reach uniformity, and improves working efficiency.

[0059] When the temperature sensor on the outer wall of the outer cylinder 31 detects that the temperature of the outer cylinder 31 exceeds the preset value, the controller 11 controls the water pump in the water tank 41 to introduce cold water into the inlet of the spiral cooling pipe 42. The cold water cools the outer cylinder 31 through the spiral cooling pipe 42, and the outer cylinder 31 cools the molten iron, realizing the intelligent cooling function of the molten iron. The cooling water carrying heat flows back into the water tank 41 for cooling.

[0060] After the slag removal and uniform mixing of the molten iron are completed, the hydraulic push rod 51 is extended by the controller 11, which pushes the guide groove 52 to rotate. The guide groove 52 squeezes the stop block 53 to move downward and compresses the buffer spring 54 to open the discharge port of the outer cylinder 31. The molten iron in the outer cylinder 31 is transported to the mold through the discharge port and the guide groove 52, thereby realizing the discharge.

[0061] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
