Description

Technical Field

[0001] This invention relates to the field of stainless steel casting processing technology, specifically to a circulating feeding device for stainless steel casting processing. Background Technology

[0002] Stainless steel castings refer to parts or components made from stainless steel through a casting process. Stainless steel has excellent corrosion resistance and mechanical properties, making it widely used in many industrial fields. Stainless steel castings possess advantages such as good corrosion resistance, mechanical properties, and machinability, and are widely used in industrial equipment, building structures, and medical equipment.

[0003] In existing technologies, stainless steel castings typically require grinding, cutting, and drilling after manufacturing, depending on various needs. Workers usually place the workpiece on a processing table for processing, and then place it in a frame to complete the unloading. Alternatively, a conveyor belt can be added to one side of the processing table, allowing the workpiece to be placed directly on it after processing, avoiding the need for workers to bend over and improving unloading efficiency. However, after processing, some debris inevitably remains on the surface of the workpiece. Furthermore, due to handling and other processes after manufacturing, stubborn impurities can easily adhere to the surface, which can affect the workshop environment. This necessitates a cleaning step after unloading, increasing the processing steps. Therefore, we propose a circulating unloading device for stainless steel casting processing.

This ensures that the workpiece is as clean as possible when it enters the next processing step, thereby improving the efficiency of subsequent processing. In addition, the dust collection component facilitates the discharge of peeled impurities and debris. During the material feeding process, the annular movable frame of this invention drives the roller to rotate, which in turn drives the rotating shaft to rotate on the fixed rod, thereby driving the rubber swing strip to rotate. This causes the end of the rubber swing strip to strike the surface of the pad, which in turn causes the bottom of the feeding frame to vibrate to a certain extent, thus facilitating the separation of debris and impurities from the bottom wall of the feeding frame and making it easier for the debris and impurities to be discharged. This invention uses the combination of side plates, movable rods and springs to provide a certain buffer for the workpieces in the feeding frame, while facilitating the removal of impurities from the workpiece surface. Additionally, rubber pads can be fixed to the surface of the side plates to reduce friction between the side plates and the workpiece surface. Attached Figure Description

[0018] 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.

[0019] Please see Figure 1-7 This invention provides a technical solution: a circulating feeding device for processing stainless steel castings, including a base plate 1 and a mounting plate 2, the mounting plate 2 being fixed to the top surface of the base plate 1, and a ring-shaped movable frame 3 being rotatably mounted on the upper end of one side of the mounting plate 2; a feeding mechanism, disposed on the surface of the ring-shaped movable frame 3 and used for circulating feeding of castings; the feeding mechanism includes: A cross-shaped connecting frame 4 is rotatably connected to the surface of the mounting plate 2. The side of the annular movable frame 3 is fixed to the end of the cross-shaped connecting frame 4. A drive motor 5, which is coaxially connected to the cross-shaped connecting frame 4, is fixedly installed on the surface of the mounting plate 2. The material feeding frame 6 is provided in multiple evenly distributed positions and fixed on the surface of the annular movable frame 3. A conveyor belt 7 that cooperates with the material feeding frame 6 is fixed on one side of the base plate 1. The material feeding frame 6 is used for placing workpieces.

[0020] After the stainless steel casting is processed, the worker places it in the upper feeding frame 6. At the same time, the drive motor 5 drives the cross-shaped connecting frame 4 to rotate, which in turn drives the annular movable frame 3 to rotate above the conveyor belt 7. After the workpiece rotates to the lower position with the annular movable frame 3, the workpiece falls from the feeding frame 6 onto the conveyor belt 7. The workpiece is collected by placing a collection container at the end of the conveyor belt 7. The end of the conveyor belt 7 can also be connected to the next processing step of the workpiece. This process can be repeated to facilitate the cyclical feeding of the workpiece.

[0021] In this embodiment, as Figures 1-5 A stripping mechanism, disposed on the surface of the annular movable frame 3 and cooperating with the unloading mechanism, is used to clean stubborn impurities on the surface of the casting; the stripping mechanism includes: The bracket 8 is fixed to one side of the mounting plate 2. A first arc-shaped limiting plate 9 is fixed to the end of the bracket 8. The first arc-shaped limiting plate 9 is in contact with the surface of the annular movable frame 3. An arc-shaped fixing frame 10 is fixed to the end face of the first arc-shaped limiting plate 9. Through the limiting of the first arc-shaped limiting plate 9 and the arc-shaped fixing frame 10, the feeding frame 6 can maintain the stability of the workpiece feeding process when it rotates. The first roller brush 11 is provided in multiple ways and is rotatably installed on the inner wall of the arc-shaped fixed frame 10. The inner wall of the feeding frame 6 is rotatably installed with multiple second roller brushes 12. The first roller brush 11 and the second roller brush 12 respectively clean the surface of the workpiece better, thereby removing stubborn stains and impurities. The stripping mechanism also includes: A fixing ring 13 is fixed to one side of the annular movable frame 3. A connecting ring 14 is rotatably connected to the inner side of the fixing ring 13. Multiple external teeth 15 are evenly fixed on the outer surface of the fixing ring 13, and multiple internal teeth 16 are evenly fixed on the inner side of the connecting ring 14. The first gear 17 is provided in multiple parts and fixed to the end of the second roller brush 12. One of them is located in the middle and is coaxially connected to the end of the second roller brush 12. The second gear 18 meshes with the internal teeth 16 for transmission. The outer side of the arc-shaped fixed frame 10 is rotatably connected to the third gear 19, which is coaxially connected to the first roller brush 11. The third gear 19 meshes with the external teeth 15 for transmission. An L-shaped fixed plate 21 is fixed on one side of the base plate 1, and a limit member is provided on one side of the connecting ring 14. It should be noted that the fixed ring 13 rotates with the annular movable frame 3, and the connecting ring 14 is rotatably connected to the fixed ring 13. However, the connecting ring 14 is limited by a limiting member to keep it stationary.

[0022] Specifically, the limiting components include: Two connecting blocks 20 are provided and symmetrically distributed and fixed on one side of the connecting ring 14. An annular protective plate 22 is fixed to the end of the L-shaped fixing plate 21. The ends of the two connecting blocks 20 are fixed to the inner side of the annular protective plate 22. By fixing the connecting blocks 20 to the annular protective plate 22, the connecting ring 14 is limited, and the transmission component is protected by the annular protective plate 22. The processed workpiece is placed in the feeding frame 6 for unloading. During this process, the annular movable frame 3 drives the fixed ring 13 to rotate synchronously, thereby driving the third gear 19 to rotate through the external teeth 15. This, in turn, drives the first roller brush 11 to rotate within the arc-shaped fixed frame 10. Simultaneously, as the feeding frame 6 rotates, it drives the second gear 18 to roll on the internal teeth 16, thereby driving the second gear 18 to rotate. Then, the second gear 18 drives one of the first gears 17 to rotate, causing one of the first gears 17 to drive the other first gears 17 to rotate. This drives multiple second roller brushes 12 to rotate within the feeding frame 6. Through the rotation of the first roller brush 11 and the second roller brush 12, the surface of the workpiece is cleaned while also being flipped, allowing the surface of the workpiece between them to be cleaned better and facilitating the removal of stubborn impurities.

[0023] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 5 A dust collection component is disposed around the periphery of the annular movable frame 3 and cooperates with the peeling mechanism for discharging impurities after peeling; the dust collection component includes: The first arc-shaped conduit 23 is disposed around the first arc-shaped limiting plate 9. The arc-shaped fixing frame 10 and the outer surface of the first arc-shaped limiting plate 9 are fixed with a plurality of first connecting pipes 24. The ends of the first connecting pipes 24 are fixed to and connected to the surface of the first arc-shaped conduit 23. The outer surface of the first arc-shaped conduit 23 is fixed with a discharge pipe 25. The discharge end of the discharge pipe 25 is connected to a dust collection device. Typically, a vacuum cleaner is used to clean the debris and impurities from the first roller brush 11 and the second roller brush 12. The debris and impurities are drawn from the first connecting pipe 24 into the first arc-shaped guide pipe 23, then into the discharge pipe 25, and finally discharged by the vacuum cleaner. At the same time, it can also adsorb the impurities remaining on the surface of the first roller brush 11 and the second roller brush 12. When the annular movable frame 3 rotates to discharge the material, the first roller brush 11 and the second roller brush 12 are always rotating, which facilitates the detachment of debris and makes it easier to adsorb and discharge the debris.

[0024] Furthermore, a second arc-shaped limiting plate 34 is slidably provided on the outer surface of the annular movable frame 3. A plurality of second connecting pipes 35 are fixed on the outer surface of the second arc-shaped limiting plate 34. A second arc-shaped conduit 36 ​​is fixed between the ends of the second connecting pipes 35. A transfer pipe 37 is fixed on the surface of the second arc-shaped conduit 36. The end of the transfer pipe 37 is fixed to and communicates with the surface of the discharge pipe 25. A mounting rod 40 is fixed on the surface of the mounting plate 2. The end of the mounting rod 40 is fixed to one side of the second arc-shaped limiting plate 34. After the cleaned workpiece is delivered to the conveyor belt 7 by the feeding frame 6, the feeding frame 6 passes through the second arc-shaped limiting plate 34 in sequence. At this time, it is connected to the dust collection equipment through the adapter pipe 37, so that the feeding frame 6 can still be cleaned by dust collection, thereby preventing impurities from contaminating the workpiece when feeding.

[0025] It is worth noting that, such as Figure 2 The top surface of the base plate 1 is fixed with a limit frame 38, and the transfer pipe 37 is fixed inside the limit frame 38. The limit frame 38 supports and reinforces the transfer pipe 37. The bottom surface of the base plate 1 is fixed with four rectangular casters 39, which facilitate the overall movement of the unloading device.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 6 A vibration assembly, located inside the annular movable frame 3 and cooperating with the dust collection assembly, is used to remove residual debris and impurities. The vibration assembly includes: A fixing rod 26 is fixed to the top surface of an L-shaped fixing plate 21. A rotating shaft 27 is rotatably connected to the end of the fixing rod 26. A roller 28 is fixed to the end of the rotating shaft 27. The roller 28 is in contact with the inner wall of the annular movable frame 3. Multiple evenly distributed rubber swing strips 29 are fixed to the outer surface of the rotating shaft 27. A gasket 30 that mates with the rubber swing strips 29 is fixed to the bottom surface of the feeding frame 6. During the material feeding process, the annular movable frame 3 drives the roller 28 to rotate, which in turn drives the rotating shaft 27 to rotate on the fixed rod 26, which in turn drives the rubber swing strip 29 to rotate. This causes the end of the rubber swing strip 29 to strike the surface of the pad 30, thereby causing the bottom of the feeding frame 6 to vibrate to a certain extent. This facilitates the separation of debris and impurities from the bottom wall of the feeding frame 6, making it easier for the debris and impurities to be discharged.

[0027] It is worth noting that, such as Figure 3 and Figure 7Both sides of the feeding frame 6 are movably connected by movable rods 31. A side plate 32 is fixed to one end of the two movable rods 31 that are close to each other. A spring 33 is sleeved on the outer surface of the movable rod 31. One end of the spring 33 is fixed to the outer surface of the feeding frame 6, and the other end of the spring 33 is fixed to the end of the movable rod 31. When the workpiece is flipped in the feeding frame 6, the cooperation between the side plate 32 and the spring 33 can provide a certain buffering effect on the workpiece. At the same time, a rubber pad can be fixed on the surface of the side plate 32 to reduce the friction between the side plate 32 and the workpiece surface.

[0028] Working principle: After the stainless steel casting is processed, the worker places it in the upper feeding frame 6. Simultaneously, the drive motor 5 rotates the cross-shaped connecting frame 4, which in turn rotates the annular movable frame 3 above the conveyor belt 7. Once the workpiece is directly below the annular movable frame 3, it falls from the feeding frame 6 onto the conveyor belt 7. A collection container is placed at the end of the conveyor belt 7 to collect the workpiece. The end of the conveyor belt 7 can also be connected to the next processing step of the workpiece. This process repeats, facilitating the cyclical feeding of workpieces. The annular movable frame 3 drives the fixed ring 13 to rotate synchronously, which in turn drives the third gear 19 to rotate via the external teeth 15. This, in turn, drives the first roller brush 11 to rotate within the arc-shaped fixed frame 10. Simultaneously, the rotation of the feeding frame 6 drives the second gear 18 to roll on the internal teeth 16, thus rotating the second gear 18. The second gear 18 then drives one of the first... The rotation of gear 17 causes one of the first gears 17 to drive the other first gears 17 to rotate, thereby driving multiple second roller brushes 12 to rotate within the feeding frame 6. Through the rotation of the first roller brush 11 and the second roller brush 12, the surface of the workpiece is cleaned and it can also be flipped, so that the surface of the workpiece between them can be cleaned better and it is easier to remove stubborn impurities. Through an external vacuum cleaner, the debris and impurities cleaned by the first roller brush 11 and the second roller brush 12 can be adsorbed from the first connecting pipe 24 into the first arc-shaped guide pipe 23, then into the discharge pipe 25, and finally discharged by the vacuum cleaner. At the same time, it can also adsorb the impurities remaining on the surface of the first roller brush 11 and the second roller brush 12. When the annular movable frame 3 rotates to feed, the first roller brush 11 and the second roller brush 12 are always in a rotating state, which facilitates the detachment of debris and facilitates the adsorption and discharge of debris.

[0029] The drive motor 5 can be purchased from the market and equipped with a separate power supply. This is a mature technology in the field and has been fully disclosed, so it will not be described again in the specification.
