Description

Technical Field

[0001] This application relates to the field of incubation technology, and in particular to an incubation block mold tilting cage and its pneumatic clamping tilting device. Background Technology

[0002] In the foundry industry, "inoculation treatment" is often used to improve the solidification structure of molten metal and enhance the performance of castings. Inoculation treatment involves adding certain types of inoculants to molten metals such as cast iron, which promote graphite nucleation, refine grains, and reduce shrinkage cavities during solidification, thereby improving the overall mechanical properties and stability of the castings.

[0003] In-mold inoculation is a widely used process primarily employed to improve the solidification structure of molten metals such as cast iron, thereby enhancing the mechanical properties and stability of castings. Its core principle involves placing a specific inoculant directly into the mold or gating system during the pouring process, allowing the molten metal to react rapidly as it flows through, promoting graphite nucleation, refining grains, and reducing defects such as shrinkage cavities. Compared to traditional furnace inoculation, in-mold inoculation offers advantages such as timely reaction and high inoculant utilization, thus gaining widespread application in the modern foundry industry.

[0004] Inoculants are typically used in solid block form, called inoculant blocks. These blocks are mainly made of alloying elements such as silicon, calcium, barium, and rare earth elements, and are characterized by moderate melting points and stable reactions. The production process includes raw material smelting, mold casting, cooling and demolding, and polishing and inspection. For ease of mass production, multiple inoculant block molds are usually placed together and transported and demolded using a casting cage.

[0005] Currently, common casting block mold cages employ a steel frame design with a pair of lifting lugs welded to the top and bottom. In practice, when the cage needs to be lifted, workers must manually attach the lifting hook to the upper lug; and when overturning the cage, unloading the mold, or forming the inoculum, the hook must be switched to the lower lug. This repeated hook-changing not only reduces production efficiency but also poses a significant safety hazard because the cage is constantly exposed to high temperatures, exposing workers to strong heat radiation. Therefore, the existing casting cage structure needs optimization to improve operational convenience and safety. Utility Model Content

[0006] In order to improve the working environment of operators and reduce the impact of heat radiation, this application provides a flipping cage for incubation block molds and a pneumatic clamping flipping device.

[0007] The technical solution for the incubation block mold flipping cage provided in this application is as follows:

[0008] A flipping cage for incubation block molds includes a cage body with lifting holes provided on the cage body;

[0009] When the cage body is unloaded, the weight of the portion of the cage body below the centerline of the hoisting hole is greater than the weight of the portion of the cage body above the centerline of the hoisting hole.

[0010] When the cage body is fully loaded, the total weight of the cage body and the load below the centerline of the hoisting hole is less than the total weight of the cage body and the load above the centerline of the hoisting hole.

[0011] By adopting the above technical solution, the lifting hole is used to connect with the pin, and the pin enables the automatic flipping of the cage body. When the cage body is unloaded, its own weight ensures that the cage body is in a bottom-down position. At this time, the inoculum mold can be placed into the cage body for inoculum casting. After the inoculum casting is completed, the cage body is fully loaded. The total weight of the part below the centerline of the lifting hole is less than the total weight of the part above the centerline of the lifting hole. At this time, the pin is inserted into the lifting hole, and then the cage body is lifted. The cage body flips and tilts the inoculum mold and inoculum out. The vibration after tilting helps to separate the mold and inoculum. After tilting, it automatically resets and can continue to the next operation. This center of gravity design enables the cage body to achieve a highly efficient and automated operation process.

[0012] The entire device features a dual automatic working cycle of automatic tilting under full load and automatic reset under no load, which can be completed simply by connecting the lifting hole and the pin. This avoids the need for frequent manual disassembly and repositioning of the hook, as required in traditional methods, and significantly improves work efficiency.

[0013] Meanwhile, the flipping and resetting actions are automatically driven by changes in the center of gravity and gravity, requiring no manual intervention or additional power. The actions are reliable and avoid exposing operators to strong heat radiation, thus improving operational safety.

[0014] Optionally, the cage body includes a base plate, on which a plurality of columns are connected, and a lower enclosure plate is installed together on the plurality of columns. The lower enclosure plate is located close to the base plate. An upper enclosure plate is installed together on the plurality of columns. The upper enclosure plate is located away from the base plate. A middle enclosure plate is installed on the plurality of columns. The middle enclosure plate is located between the upper enclosure plate and the lower enclosure plate. The distance from the middle enclosure plate to the lower enclosure plate is less than the distance from the middle enclosure plate to the upper enclosure plate. The lifting holes are formed on the middle enclosure plate, and there are two lifting holes arranged opposite each other.

[0015] By adopting the above technical solution, the layered lower, middle, and upper enclosure panels, especially the asymmetrical layout where the middle enclosure panel is closer to the lower enclosure panel, provide a basic structure for precise adjustment of the weight distribution of the lifting cage, ensuring that the center of gravity shifts from light at the top and heavy at the bottom when the cage is unloaded to heavy at the top and light at the bottom when fully loaded. Simultaneously, this layered enclosure panel design significantly enhances the overall structural strength and rigidity of the lifting cage. Two symmetrically arranged lifting holes are directly located on the middle enclosure panel, the core of the structure, ensuring balanced and stable forces during lifting, effectively reducing the risk of swaying during the flipping process, thereby directly improving operational safety and efficiency.

[0016] Optionally, the middle enclosure plate is connected to two lifting hole plates. The lifting holes include a first through hole and a second through hole. The first through hole is opened on the middle enclosure plate, and the second through hole is opened on the lifting hole plate. The first through hole and the second through hole on the same side are concentric. The end of the second through hole away from the middle enclosure plate is provided with a guide angle to facilitate the pin to be inserted into the second through hole on the cage body.

[0017] By adopting the above technical solution, a guide angle is provided at the end of the second through hole away from the middle plate, so that the pin can automatically correct its position when inserted, reducing equipment adjustment time and improving hoisting efficiency. This not only reduces the difficulty of operation, but also reduces equipment wear caused by misalignment and extends the service life of the equipment.

[0018] Optionally, the column is an angle steel, which is welded to the base plate. Several angle steels pass through the inner ring of the upper, middle, and lower surround plates and are welded to the upper, middle, and lower surround plates. The hoisting plate is welded to the outer side of the middle surround plate.

[0019] By adopting the above technical solutions, angle steel as a column is not only low in cost and easy to obtain, but also has high bending and torsional resistance, and can withstand the dynamic load when the mold is turned over. The use of angle steel columns and welding process improves the strength and durability of the cage body. In addition, several angle steels can also position the inoculation block mold, improve the stability of the inoculation block mold during the casting process. The angle steel passes through the inner ring of the surrounding plate and is welded and fixed, so that each layer of surrounding plate and column form a rigid connection, making the overall structure more solid and avoiding loosening after long-term use. The lifting hole plate is welded to the outside of the middle surrounding plate, which improves the stability of the connection between the lifting hole and the pin.

[0020] The pneumatic clamping and tilting lifting device provided in this application adopts the following technical solution:

[0021] A pneumatic clamping and tilting lifting device is used to lift the aforementioned incubation block mold tilting cage. It includes a mounting plate, with a fixed clamping arm fixedly connected to the bottom of the mounting plate and a movable clamping arm movably connected thereto. The fixed clamping arm and the movable clamping arm are arranged opposite to each other. A cylinder is mounted on the mounting plate, fixed to the mounting plate and connected to the movable clamping arm. Lifting pins are connected to the opposite sides of the fixed and movable clamping arms, and the two lifting pins are concentric. The cage body rotates around the central axis of the lifting pins.

[0022] By adopting the above technical solution, the cylinder drives the movement of the movable clamping arm. The fixed clamping arm and the movable clamping arm cooperate with each other. Under the drive of the cylinder, the clamping and release of the tilting cage body are realized. The two concentrically set lifting pins ensure that the cage body can be clamped smoothly, so that the cage body can automatically tilt around the central axis of the pins. The movable clamping arm driven by the cylinder, together with the fixed clamping arm, ensures the reliability of the clamping.

[0023] Compared to using existing clamping mechanisms to hold the cage body, this method uses a combination of rigid fixed clamping arms and movable clamping arms, driven by cylinders, and has an integrated mounting plate. The structure is robust. Compared to traditional robotic arms and large finger cylinders, the working elements are far from high-temperature areas, and there are no precision electronic components in the moving parts. It is suitable for high-temperature, heavy-load, and high-dust environments, and is suitable for heavy lifting operations.

[0024] Optionally, guide angles are provided on opposite sides of the two lifting pins to facilitate the insertion of the lifting pins into the lifting holes on the same side.

[0025] By adopting the above technical solution, the guide angle provides guidance for the lifting pin, facilitating the insertion of the lifting pin, simplifying on-site operation, improving efficiency, and thus ensuring a smooth connection between the lifting pin and the lifting hole.

[0026] Optionally, a limiting seat is provided on the side of the cylinder near the movable clamping arm. The limiting seat is fixedly connected to the mounting plate, and a limiting screw is installed on the limiting seat. The stroke of the cylinder and the movable clamping arm is adjusted by the limiting seat and the limiting screw.

[0027] By adopting the above technical solution, the combination of the limit seat and the limit screw can effectively clamp the cage body, which can prevent equipment damage caused by overtravel and avoid excessive clamping affecting the rotation of the cage body, thus improving the safety performance of the equipment. By adjusting the extension of the limit screw, the stroke can be adjusted, thereby clamping cage bodies of different sizes and improving the adaptability of the equipment.

[0028] Optionally, the mounting plate is provided with a horizontal boom and a vertical boom, a transparent front protective cover is provided on the side of the mounting plate near the movable clamping arm, and a rear protective cover is provided on the side of the mounting plate near the fixed clamping arm.

[0029] By adopting the above technical solutions, the transparent protective cover ensures operational safety without affecting the observation of the equipment, enabling timely detection of any malfunctions. It also protects the internal components of the cover. This protective structure effectively prevents foreign objects from entering and accidental contact by personnel. Furthermore, its detachable design facilitates equipment maintenance, enhancing both safety and ease of use.

[0030] Optionally, the cylinder is connected to a movable angle seat, the mounting plate has an oblong hole, the movable clamping arm passes through the oblong hole and is fixedly connected to the movable angle seat, the mounting plate is provided with a guide rail, the guide rail is provided with a slider, and the movable angle seat is mounted on the slider.

[0031] By adopting the above technical solution, the piston rod drives the movable clamping arm to achieve linear motion through the movable angle seat. The waist-shaped hole design provides sufficient space for the movable clamping arm to move. The cooperation between the guide rail and the slider ensures the smoothness of the movement of the movable clamping arm, improves the positioning accuracy, effectively reduces the frictional resistance during the movement, makes the clamping action smoother, and improves the service life of the equipment.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. By setting the position of the lifting hole and designing the appropriate weight of the lifting cage itself, the dual automation functions of automatic reset to the casting inoculation block state under no-load and automatic tilting and overturning to remove the inoculation block mold and inoculation block under full load are realized. This design relies entirely on the mechanical structure and its appropriate counterweight to achieve automatic tilting without the need for additional power or manual intervention, which greatly reduces the labor intensity of operators, avoids manual exposure to strong heat radiation, improves the safety of operation, and improves production efficiency.

[0034] 2. The layered lower, middle, and upper enclosure panels, especially the asymmetrical layout where the middle panel is closer to the lower panel, provide a fundamental structural basis for precise adjustment of the cage's weight distribution. This ensures that the cage's center of gravity shifts, being lighter at the top and heavier at the bottom when unloaded, and heavier at the top and lighter at the bottom when fully loaded. Simultaneously, this layered enclosure design significantly enhances the overall structural strength and rigidity of the cage. Two symmetrically positioned lifting holes are directly located on the core middle enclosure panel, ensuring balanced and stable forces during lifting, effectively reducing the risk of swaying during tilting, and thus directly improving operational safety and efficiency.

[0035] 3. Compared with the existing clamping mechanism for clamping the cage body, the combination of rigid fixed clamping arm and movable clamping arm, driven by cylinder, and integrated mounting plate, makes the structure robust. Compared with traditional robotic arms and large finger cylinders, the working elements are far away from high temperature areas, and there are no precision electronic components in the moving parts. It is suitable for high temperature, heavy load and high dust environments, and is suitable for heavy lifting operations.

[0036] 4. The combination of the limit seat and the limit screw can effectively clamp the cage body, which can prevent equipment damage caused by overtravel and avoid excessive clamping affecting the rotation of the cage body, thus improving the safety performance of the equipment. By adjusting the extension of the limit screw, the stroke can be adjusted, thereby clamping cage bodies of different sizes and improving the adaptability of the equipment.

[0043] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0044] This application discloses a flipping cage for incubation block molds.

[0045] like Figure 1 The incubation block mold tilting cage includes a base plate 11, and four columns 12 are welded to the top surface of the base plate 11. The four columns 12 are equidistant from each other along the circumference of the base plate 11. The four columns 12 are angle steel 121, and the four angle steel 121 are connected to the lower enclosure plate 13, the middle enclosure plate 14 and the upper enclosure plate 15. The four angle steel 121 pass through the upper enclosure plate 15, the middle enclosure plate 14 and the lower enclosure plate 13 in sequence, and are welded to the inner sidewalls of the upper enclosure plate 15, the middle enclosure plate 14 and the lower enclosure plate 13.

[0046] The distance from the middle panel 14 to the lower panel 13 is less than the distance from the middle panel 14 to the upper panel 15. Two lifting hole plates 16 are connected to opposite outer sides of the middle panel 14. The middle panel 14 and the lifting hole plates 16 share two lifting holes 161, each including a first through hole 1611 and a second through hole 1612, which are interconnected. The two first through holes 1611 are arranged opposite each other, and the four lifting holes 161 are coaxial. A guide angle 1613 is provided at the end of the second through hole 1612 away from the middle panel 14 to facilitate the insertion of the pin into the second through hole 1612.

[0047] In the unloaded state, the total weight of the cage body 1 portion below the central axis of the first through hole 1611 is greater than the total weight of the cage body 1 portion above the central axis of the first through hole 1611.

[0048] Under full load, the total weight of the cage body 1 part below the central axis of the first through hole 1611, the inoculation block, and the inoculation block mold part is less than the total weight of the cage body 1 part above the central axis of the first through hole 1611, the inoculation block, and the inoculation block mold part.

[0049] When fully loaded, the pin is inserted into the hole. When the cage body 1 is lifted, the cage body 1 will automatically flip and tilt to overturn the inoculation block and mold based on the appropriate weight configuration. After the tilting is completed, the cage body 1 will automatically flip and reset based on its own weight configuration.

[0050] In other embodiments, the cage body 1 may also be a sleeve with two opposing lifting holes 161, such that when unloaded, the total weight of the sleeve portion below the lifting holes 161 is greater than the total weight of the sleeve portion above the lifting holes 161.

[0051] Under full load, the total weight of the sleeve portion below lifting hole 161, the inoculum block, and the inoculum block mold portion is less than the total weight of the sleeve portion above lifting hole 161, the inoculum block, and the inoculum block mold portion.

[0052] This application also provides a pneumatic clamping and tilting lifting device for lifting the tilting cage of the incubation block mold of this application.

[0053] like Figure 2 , Figure 3 and Figure 4 The pneumatic clamping and tilting lifting device includes a mounting plate 2, on which a fixed angle seat 31 is fixedly connected. A cylinder 22 is fixedly mounted on the fixed angle seat 31. Two guide rails 23 are also fixedly mounted on the mounting plate 2, each with a slider 24. The two sliders 24 are connected to a movable angle seat 32. The movable angle seat 32 and the piston rod of the cylinder 22 are connected via a floating joint 27. An oblong hole 28 is provided on the mounting plate 2, located between the two guide rails 23. The bottom of the movable angle seat 32 is connected to… A movable clamping arm 42 is attached, passing through the oblong hole 28 and fixedly connected to the bottom of the movable angle seat 32. The movable clamping arm 42 is located at one end of the mounting plate 2, and a fixed clamping arm 41 is installed at the other end of the mounting plate 2. The fixed clamping arm 41 and the movable clamping arm 42 are arranged opposite to each other. A lifting pin 43 is connected to the opposite side of the fixed clamping arm 41 and the movable clamping arm 42. The two lifting pins 43 are concentric, and the cage body 1 can rotate around the central axis of the lifting pins 43. A guide angle 1613 is provided on the opposite side of the two lifting pins 43 to facilitate the insertion into the lifting hole 161.

[0054] Two limit seats 25 are also fixed on the mounting plate 2. The movable angle seat 32 is located between the two limit seats 25. The limit seats 25 are fixed on the mounting plate 2 and are threadedly connected to limit screws 26. By adjusting the limit screws 26, the clamping force can be precisely controlled, and the stroke of the cylinder 22 and the movable clamping arm 42 can be adjusted to prevent excessive clamping from affecting the rotation of the cage body 1.

[0055] A transparent front protective cover 51 is provided on the side of the mounting plate 2 near the movable clamping arm 42, and a rear protective cover 52 is provided on the side near the fixed clamping arm 41. The front protective cover 51 covers components such as the movable angle seat 32, the limit seat 25, the limit screw 26, the guide rail 23, and the slider 24, while the rear protective cover 52 covers components such as the cylinder 22 and the fixed angle seat 31. The mounting plate 2 is also provided with a horizontal lifting arm 53, a vertical lifting arm 54, and a control rod 21 for controlling the movement of the lifting device.

[0056] like Figure 5 By moving the lifting device, the lifting pin 43 is aligned with the lifting hole 161. The control cylinder 22 drives the movable clamping arm 42 to move towards the fixed clamping arm 41, so that the lifting pin 43 is inserted into the corresponding lifting hole 161, thereby achieving the clamping of the cage body 1 by the lifting device. The limit screw 26 restricts the movable clamping arm 42 from over-clamping the cage body 1. After clamping is completed, the lifting device is controlled to raise the cage body 1 to a suitable position so that the cage body 1 can achieve its full-load automatic overturning and tipping.

[0057] The implementation principle of this application embodiment is as follows: When placing the incubation block module, first operate the bridge crane to lift the empty incubation block mold flip cage. At this time, the empty cage body 1 is in the state of bottom plate 11 facing down and upper plate 15 facing up. Place multiple empty cage bodies 1 on the pallet and load the incubation block mold.

[0058] Then, the main trolley of the bridge crane is operated to lift the pallet to the casting inoculum block station. After the inoculum block is cast, the main trolley of the bridge crane is operated to lift the pallet carrying the inoculum block mold tilting cage to the inoculum block sorting area.

[0059] After the hoist cage 1 reaches the designated area, operate the auxiliary trolley of the bridge crane to lift the pneumatic clamping and tilting spreader for the inoculated block mold above the inoculated block mold tilting cage, and then lower the spreader to the position where it clamps the inoculated block mold tilting cage. Operate the pneumatic control button on the pneumatic clamping and tilting spreader to clamp the inoculated block mold tilting cage.

[0060] After confirming accurate clamping, the auxiliary trolley of the bridge crane is operated to raise the lifting device to a suitable position. Under full load, the total weight of the portion above the lifting hole 161 of the cage body 1, containing the inoculum mold and inoculum blocks, is greater than the total weight of the portion below the lifting hole 161. Due to this appropriate overall weight distribution, the cage body 1 automatically tilts and overturns, releasing the inoculum mold and inoculum blocks from within. Furthermore, the vibration after tilting facilitates the separation of the mold and inoculum blocks. After tilting, the cage body 1, again relying on its appropriate weight distribution, automatically tilts back to its initial state for casting inoculum blocks. The bridge crane is then operated to place multiple cage bodies 1 into a pallet. The bridge crane is then operated to transfer the pallet to the workstation where the inoculum mold is loaded, repeating the above cycle.

[0061] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
