Description

Technical Field

[0001] This application relates to the technical field of chill processing, and particularly to a sand hanging device for the non-working surface of a chill. Background Art

[0002] In the casting field, a chill is a commonly used casting auxiliary material, which plays an important role in improving the solidification conditions of castings and refining grains. However, in the traditional use of chills, the treatment of the non-working surface of the chill is often not taken seriously enough. Usually, during storage, transportation, and preliminary processing of the chill, various impurities, rust, and other pollutants will accumulate on its non-working surface.

[0003] During storage, transportation, and preliminary processing of the chill, various impurities or rust and other pollutants may accumulate on the non-working surface of the chill. After sand hanging on the non-working surface of the chill, the pollutants still remain between the chill and the sand hanging layer. The residue of the pollutants will cause the bonding force between the sand hanging layer and the non-working surface of the chill to decrease, and the sand hanging layer is likely to fall off during subsequent casting, and even may lead to the generation of casting defects, seriously affecting the product quality of castings, and there are obvious deficiencies. Utility Model Content

[0004] In order to improve the product quality of castings, this application provides a sand hanging device for the non-working surface of a chill.

[0005] The sand hanging device for the non-working surface of a chill provided by this application adopts the following technical scheme:

[0006] A sand hanging device for the non-working surface of a chill includes a sand hanging box. A workbench is arranged in the sand hanging box. A plurality of placement grooves for placing chills are formed on the workbench. A cleaning component and a sand hanging mechanism are arranged on the sand hanging box. The sand hanging mechanism is used to make a sand hanging layer on the surface of the chill. The cleaning component includes a mounting plate slidably connected to the surface of the workbench. A plurality of abrasive plates are arranged on the bottom surface of the mounting plate. The bottom surface of the abrasive plate abuts against the surface of the non-working surface of the chill. Screws and guide rods are respectively arranged at both ends of the workbench. The screw is rotatably connected in the sand hanging box. One end of the mounting plate is threadedly connected to the screw, and the other end is slidably connected to the guide rod. A first motor is arranged on the outer side wall of the sand hanging box. The output shaft of the first motor is coaxially and fixedly connected to the screw.

[0007] By adopting the above technical solution, during sand hanging, the worker places the chill in the placement groove, and then starts the first motor. The first motor drives the screw to rotate, and the rotation of the screw drives the mounting plate to move. The abrasive plate slides on the surface of the workbench as the mounting plate moves. When the abrasive plate contacts the non-working surface of the chill, it effectively scrapes off the impurities, rust and other pollutants on the surface of the chill. The setting of the cleaning component realizes the synchronous and all-round cleaning of the non-working surfaces of multiple chills, improves the cleanliness of the non-working surfaces of the chills before sand hanging, thereby reducing the possibility of adverse effects on the casting caused by pollutant residues, and improving the product quality of the casting.

[0008] Optionally, a rotating component is provided on the mounting plate. The rotating component includes a driving rod provided on the abrasive plate. A plurality of the driving rods are rotatably connected in the mounting plate. One end of the driving rod away from the abrasive plate is fixedly connected with a gear. A plurality of the gears are rotatably arranged on the surface of the mounting plate. Adjacent gears are meshed with each other. A rack plate is fixedly connected to the inner side wall of the sand hanging box, and the rack plate is meshed with the gear close to the rack plate.

[0009] By adopting the above technical solution, the movement of the mounting plate drives the gear to move along the length of the rack plate. Since the rack plate is fixedly connected to the inner side wall of the sand hanging box, the rack plate drives the moving gear to rotate. At the same time, under the transmission action of the meshing of multiple gears, multiple gears rotate synchronously and drive the driving rod to rotate. The driving rod makes the abrasive plate rotate to clean the non-working surface of the chill. The contact angle between the rotating abrasive plate and the chill is constantly changing, and the pollutants on the chill are subjected to frictional forces in different directions. The greater frictional force enables the abrasive plate to scrape the surface of the chill more powerfully, and for the rust and stubborn impurities with stronger adhesion, it can more effectively remove them from the surface of the chill, thereby further reducing the possibility of pollutant residues on the non-working surface of the chill.

[0010] Optionally, the sand hanging mechanism includes a mixing box provided on the outer side wall of the sand hanging box. A mixing component is provided in the mixing box. A feeding pipe is communicated with the mixing box. A feeding pump is provided on the feeding pipe. The discharging end of the feeding pipe extends into the sand hanging box and is communicated with a discharging channel. A discharging spray gun corresponding to each of the plurality of placement grooves is communicated with the discharging channel, and the discharging direction of the discharging spray gun is set to face the non-working surface of the chill.

[0011] By adopting the above technical solution, after cleaning is completed, the worker starts the feeding pump. The feeding pump transports the uniformly mixed raw materials of the sand-hanging layer to the discharge channel through the feeding pipe. The raw materials of the sand-hanging layer are finally sprayed from the discharge spray gun onto the non-working surface of the corresponding chill. The setting of the sand-hanging mechanism only requires the worker to start the feeding pump after cleaning to achieve synchronous sand-hanging of multiple chill blocks, improving the sand-hanging efficiency. At the same time, the discharge spray guns corresponding to the placement grooves one by one can ensure that the sand-hanging materials accurately cover the non-working surface of the chill, improving the accuracy and quality of sand-hanging.

[0012] Optionally, the stirring assembly includes a main shaft and a plurality of auxiliary shafts rotatably connected in the stirring box. The main shaft is arranged at the center of the stirring box, and the plurality of auxiliary shafts are circumferentially and uniformly distributed on the outer peripheral side of the main shaft. A plurality of stirring rods are arranged on both the main shaft and the plurality of auxiliary shafts. A driving assembly for driving the main shaft and the auxiliary shafts to rotate synchronously is arranged in the stirring box.

[0013] By adopting the above technical solution, before sand-hanging, the driving assembly drives the main shaft and the plurality of auxiliary shafts to rotate synchronously. The rotation of the main shaft and the auxiliary shafts drives the stirring rods to rotate in the stirring box. When the stirring rods rotate, they fully mix various raw materials for sand-hanging in the stirring box. The setting of the stirring assembly and the driving assembly ensures the fluidity of the sand-hanging layer material, reducing the possibility of phenomena such as caking or stratification of the mixed sand-hanging raw materials, thereby reducing the possibility of blockage of the feeding pump and the feeding pipe, resulting in the interruption of the sand-hanging process. At the same time, the uniform sand-hanging raw materials can improve the quality of the sand-hanging layer on the non-working surface of the chill, so that the sand-hanging layer firmly adheres to the surface of the chill, and further reduces the possibility of the sand-hanging layer detaching from the chill and reducing the quality of the casting product, and the quality of the casting product is further improved.

[0014] Optionally, the driving assembly includes a second motor arranged on the stirring box. The output shaft of the second motor is fixedly connected to the main shaft. A driving gear is coaxially and fixedly connected to the main shaft. A driven gear corresponding to each auxiliary shaft is meshed with the driving gear. The driven gear is fixedly connected to the auxiliary shaft. A gear ring meshing with the plurality of driven gears is arranged on the inner peripheral side wall of the stirring box.

[0015] By adopting the above technical solution, after the second motor is started, it drives the main shaft to rotate, the main shaft drives the driving gear to rotate, the driving gear drives the multiple meshing driven gears to rotate, and the driven gear drives the multiple secondary shafts to rotate synchronously. At the same time, under the setting of the ring gear, the driven gear will move circumferentially along the ring gear during the rotation process, and the movement of the driven gear drives the multiple secondary shafts to move along the inner circumferential side wall of the mixing box. The circumferentially moving secondary shaft enables the stirring rod to cover every corner of the mixing box, ensuring that the raw materials of the sand layer can be fully stirred both in the central area and the edge area of ​​the mixing box. The setting of the drive component further improves the uniformity of the raw materials of the sand layer, avoiding the occurrence of local raw material accumulation or uneven mixing that affects the sand hanging process.

[0016] Optionally, the placement slot is a through slot, and a fixed plate is slidably connected to the sand hanging box. Magnetic blocks corresponding to the multiple placement slots are embedded on the surface of the fixed plate. The magnetic blocks are used to adsorb the working surface of the cold iron. Multiple cylinders are arranged in the sand hanging box, and the output shafts of the cylinders are fixedly connected to the bottom surface of the fixed plate. In the initial state, the surface of the fixed plate is tightly fitted with the bottom surface of the workbench.

[0017] By adopting the above technical scheme, the adsorption effect of the magnetic block combined with the restriction of the side wall of the placement slot provides a stable and reliable fixing method for the chiller. During the cleaning and sanding process, the chiller will not be displaced or shaken due to external force, ensuring that the sanding layer can evenly cover the non-working surface of the chiller. When the sanding process is completed, the worker starts the cylinder, and the cylinder drives the fixed plate to move away from the discharge channel. The movement of the fixed plate drives the chiller to move out of the placement slot. This arrangement reduces the inconvenience caused by the volume of the placement slot to the removal of the chiller, making it convenient for workers to take out the chiller that has been sanded from the sanding box.

[0018] Optionally, a loading door and a discharging door are hinged on the sand hanging box, and the loading door and the discharging door are both made of transparent material.

[0019] By adopting the above technical solution, the box door made of transparent material makes it convenient for workers to observe the cleaning and working status inside the sand hanging box, and it is convenient for workers to control the sand hanging process.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. The present application provides a cleaning component, which realizes the synchronous and all-round cleaning of multiple non-working surfaces of chillers, thereby improving the cleanliness of the non-working surfaces of chillers before sanding, thereby reducing the possibility of adverse effects of residual pollutants on castings, and improving the product quality of castings;

[0022] 2. By providing a stirring assembly and a driving assembly, the present application ensures the fluidity of the sand-hanging layer material. This reduces the possibility of phenomena such as caking or delamination occurring in the mixed sand-hanging raw materials, thereby reducing the possibility of blockage in the feeding pump and feeding pipe, which could lead to interruption of the sand-hanging process. At the same time, the uniform sand-hanging raw materials can improve the quality of the sand-hanging layer on the non-working surface of the chill, enabling the sand-hanging layer to firmly adhere to the surface of the chill, and further reducing the possibility of the sand-hanging layer detaching from the chill and degrading the quality of the cast product, thus further improving the quality of the cast product.

Detailed Description of the Embodiment

[0028] The following further elaborates on the present application in conjunction with the attached Figures 1-4 drawings.

[0029] The embodiment of the present application discloses a sand-hanging device for the non-working surface of a chill.

[0030] Refer to Figure 1 and Figure 2, A sand hanging device for the non-working surface of a chill includes a sand hanging box 1. Inside the sand hanging box 1, a workbench 2 is fixedly installed. The upper and lower end faces of the workbench 2 respectively enclose a feeding area 101 and a discharging area 102 with the inner side walls of the sand hanging box 1. Feeding doors 1011 and discharging doors 1021 are respectively hinged in the areas of the sand hanging box 1 where the feeding area 101 and the discharging area 102 are located. The feeding doors 1011 and the discharging doors 1021 are both made of transparent materials so that workers can observe the sand hanging situation inside the sand hanging box 1.

[0031] Refer to Figure 2 and Figure 3 , A plurality of placement grooves 21 distributed in an array are arranged on the surface of the workbench 2 in an array. The placement grooves 21 are through grooves. A fixing plate 3 is slidably connected inside the box body. Magnets 31 corresponding to the plurality of placement grooves 21 one by one are embedded on the surface of the fixing plate 3. The magnets 31 are arranged directly below the placement grooves 21. The magnets 31 are used to adsorb the chill. Cylinders 32 are fixedly installed at the four corners of the inner bottom surface of the sand hanging box 1. The output shafts of the cylinders 32 are fixedly connected to the bottom surface of the fixing plate 3. During feeding, the top surface of the fixing plate 3 is in close contact with the bottom surface of the workbench 2. A sand hanging mechanism 4 and a cleaning component 5 are arranged on the sand hanging box 1. The sand hanging mechanism 4 is used to process the sand hanging layer on the non-working surface of the chill, and the cleaning component 5 is used to clean impurities, rust and other pollutants on the non-working surface of the chill.

[0032] During sand hanging, the worker opens the feeding door 1011 and places a plurality of chills in the fixing grooves. At this time, the non-working surface of the chill faces the feeding area 101, and the working surface of the chill is adsorbed by the magnets 31. Under the adsorption of the magnets 31 and the restriction of the side walls of the placement grooves 21, the chills are firmly fixed in the feeding area 101. During the cleaning and sand hanging processes, the chills will not move or shake due to external forces, ensuring that the sand hanging layer can evenly cover the non-working surface of the chill. Subsequently, the worker starts the cleaning component 5 to clean the non-working surface of the chill. After cleaning, the sand hanging operation is carried out through the sand hanging mechanism 4. After the sand hanging layer is processed, the worker starts the cylinders 32. The cylinders 32 drive the fixing plate 3 to move in a direction away from the feeding area 101. The movement of the fixing plate 3 drives the chills to move to a state where they are separated from the placement grooves 21. At this time, the worker opens the discharging door 1021 and takes out the chills with sand hanging on the fixing plate 3 from the discharging area 102.

[0033] Refer to Figure 2 and Figure 3, the cleaning component 5 includes a mounting plate 51 slidably connected to the surface of the workbench 2. A plurality of abrasive plates 52 are provided on the bottom surface of the mounting plate 51, and the bottom surface of the abrasive plate 52 abuts against the non-working surface of the chill. Screws 53 and guide rods 54 are respectively provided at opposite ends of the workbench 2. The screw 53 is rotatably connected within the loading area 101, and the guide rod 54 is fixedly connected to the workbench 2. One end of the mounting plate 51 is threadedly connected to the screw 53, and the other end is slidably connected to the guide rod 54. A first motor 55 is fixedly installed on the outer side wall of the hanging sand box 1, and the output shaft of the first motor 55 is coaxially and fixedly connected to the screw 53.

[0034] After the chill is fixed, the worker starts the first motor 55. The first motor 55 drives the screw 53 to rotate. The rotation of the screw 53 drives the mounting plate 51 to move. The abrasive plate 52 slides on the surface of the workbench 2 as the mounting plate 51 moves. When the abrasive plate 52 contacts the non-working surface of the chill, it effectively scrapes off contaminants such as impurities and rust on the surface of the chill. The setting of the cleaning component 5 realizes the synchronous and all-round cleaning of the non-working surfaces of multiple chills, improves the cleanliness of the non-working surfaces of the chills before sand hanging, thereby reducing the possibility of adverse effects on the casting caused by residual contaminants, and improving the product quality of the casting.

[0035] Refer to Figure 2 and Figure 3 , in order to further improve the cleaning effect of the cleaning component 5, a rotating component 6 is provided on the mounting plate 51. The rotating component 6 includes a driving rod 61 fixedly connected to the abrasive plate 52. Each driving rod 61 is rotatably connected inside the mounting plate 51. One end of the driving rod 61 away from the abrasive plate 52 is fixedly connected with a gear 62. A plurality of gears 62 are rotatably connected to the surface of the mounting plate 51 and are meshed with each other adjacent to the gears 62. A rack plate 63 is meshed with the outermost gear 62. The rack plate 63 is fixedly installed on the inner side wall of the hanging sand box 1, and the length direction of the rack plate 63 is parallel to the length direction of the screw 53.

[0036] During the process of the mounting plate 51 cleaning along the surface of the workbench 2, the gear 62 meshed with the rack plate 63 on the mounting plate 51 rotates. At the same time, under the transmission action of the mutual meshing of the plurality of gears 62, the plurality of gears 62 rotate synchronously and drive the driving rod 61 to rotate. The driving rod 61 makes the abrasive plate 52 rotate to clean the non-working surface of the chill. The contact angle between the rotating abrasive plate 52 and the chill is constantly changing. The contaminants on the chill are subjected to frictional forces in different directions. The larger frictional force enables the abrasive plate 52 to scrape the surface of the chill more forcefully. For rust and stubborn impurities with stronger adhesion, they can be more effectively removed from the surface of the chill, thereby further reducing the possibility of contaminants remaining on the non-working surface of the chill.

[0037] Refer to Figure 3 and Figure 4, the sand hanging mechanism 4 includes a mixing box 41 arranged on the outer side wall of the sand hanging box 1. Various raw materials for preparing the sand hanging layer are stored in the mixing box 41. A mixing assembly 42 for mixing various raw materials is arranged in the mixing box 41. The mixing assembly 42 includes a main shaft 421 rotatably connected inside the mixing box 41 and a plurality of auxiliary shafts 422. In this embodiment, the number of auxiliary shafts 422 is four. The main shaft 421 is arranged at the central position of the mixing box 41, and the four auxiliary shafts 422 are evenly distributed in a circumferential manner on the outer peripheral side of the main shaft 421. A plurality of stirring rods 423 are fixedly connected to both the main shaft 421 and the auxiliary shafts 422. A driving assembly 43 for driving the main shaft 421 and the auxiliary shafts 422 to rotate synchronously is arranged in the mixing box 41.

[0038] Referring to Figure 3 and Figure 4 , the driving assembly 43 includes a second motor 431 fixedly installed on the top surface of the mixing box 41. The output shaft of the second motor 431 is fixedly connected to the main shaft 421. A driving gear 432 is fixedly connected to the main shaft 421. A driven gear 433 corresponding to each auxiliary shaft 422 is meshed with the driving gear 432. The driven gear 433 is fixedly connected to the rod body of the corresponding auxiliary shaft 422. A gear ring 434 that is meshed with the four driven gears 433 together is fixedly connected to the inner circumferential side wall of the mixing box 41. A support block is fixedly connected to the auxiliary shaft 422 near the inner top wall of the mixing box 41. An annular groove that is slidably matched with the support block is formed on the inner top wall of the mixing box 41.

[0039] Before sand hanging, start the second motor 431. The second motor 431 drives the main shaft 421 to rotate. The main shaft 421 drives the driving gear 432 to rotate. The driving gear 432 drives the meshed plurality of driven gears 433 to rotate, thereby realizing the synchronous rotation of the plurality of auxiliary shafts 422. At the same time, under the setting of the gear ring 434, the driven gear 433 will move circumferentially along the gear ring 434 during rotation. The movement of the driven gear 433 drives the plurality of auxiliary shafts 422 to move along the inner circumferential side wall of the mixing box 41. The circumferentially moving auxiliary shafts 422 enable the stirring rods 423 to cover all corners inside the mixing box 41, ensuring that the raw materials of the sand hanging layer can be fully stirred whether in the central area or the edge area of the mixing box 41. The settings of the driving assembly 43 and the mixing assembly 42 realize the all-round stirring of the mixed raw materials inside the mixing box 41, thereby improving the uniformity of the raw materials of the sand hanging layer and avoiding the situation that the hanging sand process is affected due to local raw material accumulation or uneven mixing.

[0040] Referring to Figure 3 and Figure 4, a feeding pipe 44 is connected to the bottom of the mixing box 41, a feeding pump 45 is installed on the feeding pipe 44, the discharging end of the feeding pipe 44 extends into the sand hanging box 1 and is connected with a discharging channel 46, and discharging spray guns 47 corresponding to a plurality of placing grooves 21 one by one are connected to the discharging channel 46. The discharging direction of the discharging spray gun 47 faces the non-working surface of the chill.

[0041] After the stirring is completed, the worker starts the feeding pump 45. The feeding pump 45 conveys the uniformly mixed sand hanging layer raw materials into the discharging channel 46 through the feeding pipe 44. The sand hanging raw materials are finally sprayed from the discharging spray gun 47 onto the corresponding non-working surface of the chill. The setting of the sand hanging mechanism 4 only requires the worker to start the feeding pump 45 after the cleaning is completed to realize the synchronous sand hanging of multiple chill blocks, improving the sand hanging efficiency. At the same time, the discharging spray guns 47 corresponding to the placing grooves 21 one by one can ensure that the sand hanging material accurately covers the non-working surface of the chill, improving the accuracy and quality of sand hanging.

[0042] The implementation principle of the sand hanging device for the non-working surface of the chill in the embodiment of the present application is as follows: During sand hanging, the worker opens the feeding door 1011 to place multiple chills in the fixing grooves. At this time, the non-working surface of the chill faces the feeding area 101, and the working surface of the chill is adsorbed by the magnetic block 31. Under the adsorption of the magnetic block 31 and the restriction of the side wall of the placing groove 21, the chill is fixed in the feeding area 101. Subsequently, the worker starts the first motor 55 and the second motor 431. The first motor 55 drives the screw 53 to rotate, and the rotation of the screw 53 drives the mounting plate 51 to move. The abrasive plate 52 slides on the surface of the workbench 2 as the mounting plate 51 moves. When the abrasive plate 52 contacts the non-working surface of the chill, it effectively scrapes off the impurities, rust and other pollutants on the surface of the chill. At the same time, the second motor 431 drives the stirring assembly 42 to complete the mixing and stirring of various raw materials. After the cleaning and stirring are completed, the worker starts the feeding pump 45. The feeding pump 45 conveys the uniformly mixed sand hanging layer raw materials into the discharging channel 46 through the feeding pipe 44. The sand hanging raw materials are finally sprayed from the discharging spray gun 47 onto the corresponding non-working surface of the chill and finally form a sand hanging layer. The setting of the cleaning assembly 5 realizes the synchronous and all-round cleaning of the non-working surfaces of multiple chills, improving the cleanliness of the non-working surfaces of the chills before sand hanging, thereby reducing the possibility of adverse effects on the casting caused by pollutant residues and improving the product quality of the casting.

[0043] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
