Description

Technical Field

[0001] The present invention relates to the technical field of casting processing, and in particular to a sand integrated conveying line for a reducer housing based on an intelligent casting island. Background Technique

[0002] The reducer housing is an important part of the reducer. It is mostly made of cast iron material, has good rigidity and corrosion resistance, can effectively prevent external substances from invading, and protect the internal components from damage. The reducer housing usually has a complex internal structure, such as cavities, holes, ribs of various shapes, etc. The casting process can present these complex design details completely by making precise molds, meeting the functional and structural requirements of the reducer.

[0003] When casting and processing the reducer housing, it is necessary to process the casting sand into a shape matching the reducer housing in the casting sand box. For example, a Chinese patent with the publication number CN115255337B discloses an assembly adjustable casting sand box for sand casting. This device avoids the situation that the quality of the workpiece is damaged due to a large number of bubbles in the molten metal by setting the first drive shaft and the second drive shaft. And when cleaning the sand box, the sand box is reversed by the second motor, reducing the difficulty of cleaning the casting sand box and improving the efficiency of cleaning the sand inside the sand box; When filling and trimming the shape of the casting sand according to the shape of the workpiece, it is necessary to press and compact the casting sand through a die head. Then, due to the friction between the casting sand grains, when the casting sand is pressed, the casting sand in the area close to the die head can be fully extruded. However, for the casting sand far from the die head, due to the insufficient transmission of the extrusion force, the compaction degree of some casting sand will be poor, resulting in pores in the casting sand, which will affect the forming accuracy of the reducer housing mold embryo and further affect the forming quality of the workpiece. Summary of the Invention

This can not only improve the filling compactness of the casting sand, but also help to keep the compactness of the casting sand in each area consistent, thereby effectively reducing the probability of voids in the casting sand, and further effectively improving the casting processing accuracy and surface roughness of the workpiece, so as to solve the problems raised in the above background technique.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 to 9 , the present invention provides a technical solution: A sand integrated conveying line for a reducer box body based on an intelligent casting island, comprising a first fixing frame 11, a second fixing frame 47, a first fixing plate 14 and a second fixing plate 19. A support rod 12 is fixedly connected between the first fixing frame 11 and the second fixing frame 47. A connecting sleeve 20 is fixedly connected to the inner side of the second fixing plate 19. A die sleeve 27 is arranged inside the connecting sleeve 20. A repressing assembly is arranged inside the die sleeve 27; The repressing assembly includes a movable plate 30 slidably connected to the die sleeve 27. A pressing plate 34 is fixedly connected to the lower end of the movable plate 30. The movable plate 30 penetrates through the upper and lower ends of the die sleeve 27. A toothed plate 35 is rotatably connected to the outer surface of the upper end of the second fixing plate 19. A connecting plate 22 is fixedly connected to the outer surface of the upper end of the toothed plate 35. The connecting plate 22 is connected with a pressing wheel 40 through a movable part. The pressing wheel 40 is in rolling contact with the outer surface of the upper end of the movable plate 30.

[0021] An installation groove 31 is embedded and opened on the inner side of the die sleeve 27. A traction strip 32 is fixedly connected to the upper end surface of the inner surface of the installation groove 31. A sliding plate 33 is fixedly connected to the lower end of the traction strip 32. The sliding plate 33 is in sliding contact with the inner surface of the installation groove 31. The sliding plate 33 is fixedly connected to the movable plate 30. The movable plate 30 is in an arc shape. The traction strip 32 is made of an elastic material. The pressing plate 34 is in an annular shape.

[0022] By adopting the above technical solution, when casting and processing the reducer housing, it is necessary to fill and trim the core according to the shape and size of the reducer housing. Insufficient compactness of the casting sand during the filling process will have an adverse impact on the casting processing accuracy and surface roughness of the casting. Therefore, a repressing assembly is provided. The support rod 12 fixedly supports the fixing frame one 11 and the fixing frame two 47. After the casting sand is filled, the external driving force is used to drive the toothed plate 35 to perform a circular motion. The toothed plate 35 will drive the connecting plate 22 to run synchronously. The connecting plate 22 rotatably supports the extrusion wheel 40 through the movable part. During the process of the connecting plate 22 driving the extrusion wheel 40 to perform a circular motion, it will rollingly contact the upper surface of the movable plate 30. Under the action of gravity, the extrusion wheel 40 will extrude the movable plate 30. The movable plate 30 drives the extrusion plate 34 to extrude the casting sand inside the die sleeve 27, so as to effectively improve the filling compactness of the casting sand, effectively reduce the probability of voids in the casting sand, and further effectively improve the casting processing accuracy and surface roughness of the workpiece. During the downward movement of the movable plate 30, it will drive the sliding plate 33 to move downward synchronously. When the sliding plate 33 moves inside the installation groove 31, it will stretch the traction bar 32. When the extrusion wheel 40 is separated from the movable plate 30, the movable plate 30 will move upward and reset under the elastic force of the traction bar 32, so that the upper surface of the movable plate 30 is higher than the upper end of the die sleeve 27.

[0023] Specifically, as Figure 5 , Figure 8 and Figure 9 shown, a driving part is arranged on the outer side of the fixing plate two 19. The driving part includes a motor 46 fixedly connected to the lower outer surface of the fixing plate two 19. The upper end of the output shaft of the motor 46 is fixedly connected with a driving rod 45. The driving rod 45 penetrates to the upper side of the fixing plate two 19 and is in rotational contact with the fixing plate two 19. The upper end of the driving rod 45 is fixedly connected with a runner 43. The lower outer surface of the runner 43 is fixedly connected with a top rod 44. The top rod 44 is in meshing transmission connection with the toothed plate 35.

[0024] The number of the top rods 44 is several groups and is distributed in a circular array. The movable part includes a chute 38 penetratingly opened on the outer surface of the connecting plate 22. A rotating shaft 39 is slidably connected to the inner side of the chute 38. An extrusion wheel 40 is rotatably connected to the outer surface of the rotating shaft 39. The number of the connecting plates 22, the rotating shafts 39 and the runners 43 is two groups and is symmetrically distributed. The toothed plate 35 is in a circular ring shape.

[0025] By adopting the above technical solution, when performing the repressing operation on the foundry sand, the motor 46 is started and run. The output shaft of the motor 46 will drive the driving rod 45 to rotate synchronously. The driving rod 45 drives the runner 43 to rotate. During the movement of the runner 43, the ejector rod 44 below it will be driven to do circular motion. During the rotation of the ejector rod 44, it will be successively engaged into the inside of the toothed plate 35. Thus, the toothed plate 35 is driven to do circular motion by the ejector rod 44. Then, the connecting plate 22 is driven to rotate synchronously by the toothed plate 35. The connecting plate 22 slidably supports the rotating shaft 39 through the chute 38. The rotating shaft 39 can linearly slide inside the chute 38. The rotating shaft 39 rotatably supports the extrusion wheel 40. During the movement of the connecting plate 22, it will drive the extrusion wheel 40 to do circular motion through the rotating shaft 39. Thus, the extrusion wheel 40 can roll over the upper end of the movable plate 30, and the movable plate 30 is pushed to slide downward by the extrusion wheel 40 for the repressing operation.

[0026] Specifically, as Figure 1 , Figure 4 and Figure 6 shown, a forming assembly is arranged between the first fixing frame 11 and the second fixing frame 47. The forming assembly includes a hydraulic rod 25 fixedly connected to the outer surface of the lower end of the second fixing frame 47. The output end of the hydraulic rod 25 is fixedly connected to the die sleeve 27. A retaining ring 26 is fixedly connected to the outer surface of the upper end of the die sleeve 27. A bracket 24 is fixedly connected to the lower surface of the first fixing frame 11. A casting box 13 is snap-fitted to the outer surface of the upper end of the bracket 24.

[0027] A guide rod 15 is fixedly connected to the outer surface of the upper end of the first fixing plate 14. A movable seat 17 is slidably connected to the outer surface of the guide rod 15. The guide rod 15 penetrates through the upper side of the second fixing plate 19 and is slidably connected to the second fixing plate 19. A module 18 is rotatably connected to the outer surface of the guide rod 15. The upper outer surface of the movable seat 17 is in rotational contact with the module 18.

[0028] A spring 16 is fixedly connected to the outer surface of the lower end of the movable seat 17. The spring 16 is sleeved outside the guide rod 15. A washer 23 is fixedly connected to the inner surface of the upper end of the first fixing plate 14. The washer 23 is in a circular ring shape. The outer surface of the upper end of the washer 23 is fixedly connected to the outer surface of the lower end of the bracket 24. The module 18 is located between the die sleeve 27 and the casting box 13.

[0029] By adopting the above technical solution, when forming the sand mold, the rotating module 18 is rotated with the guide rod 15 as the fulcrum, so that the module 18 is located between the mold sleeve 27 and the casting box 13. The spring 16 elastically supports the module 18 through the movable seat 17. Then, the hydraulic rod 25 is started to operate, and the mold sleeve 27 is driven to move downward by the hydraulic rod 25. After the mold sleeve 27 moves downward for a certain distance, its lower surface will contact the upper surface of the module 18 and drive the module 18 to move downward synchronously. The guide rod 15 can play a good sliding guiding role for the module 18. The module 18 will drive the movable seat 17 to move downward synchronously and compress the spring 16. Then, the mold sleeve 27 will drive the module 18 to move downward synchronously. The fixing frame two 47 supports the bracket 24 through the washer 23. The casting box 13 is clamped to the upper side of the bracket 24. At the same time, an appropriate amount of casting sand is filled in the casting box 13. The mold sleeve 27 will contact the upper side of the casting box 13 through the lower end of the module 18, so that the upper and lower ends of the module 18 are closely attached to the connecting sleeve 20 and the casting box 13 respectively. The casting sand is extruded and formed through the cooperation of the module 18 and the mold sleeve 27, so that a casting cavity matching the reducer box body is formed on the surface of the casting sand, and then the rapid forming operation of the casting sand can be realized. Then, the mold sleeve 27 is lifted upward by the hydraulic rod 25. As the mold sleeve 27 gradually moves upward, the module 18 and the movable seat 17 gradually move upward along the surface of the guide rod 15 under the elastic force of the spring 16. Then, the module 18 is rotated to the outside with the guide rod 15 as the fulcrum. Subsequently, the mold sleeve 27 is pushed downward again by the hydraulic rod 25 to the upper side of the casting box 13. Then, the reducer box body is cast between the mold sleeve 27 and the casting box 13. By setting the forming assembly, the casting sand can be quickly pressed and formed, which can effectively improve the casting processing efficiency and quality of the reducer box body, and can also effectively reduce the processing error.

[0030] Specifically, as Figure 5 shown in Figure 8 the figure, a knocking assembly is arranged on the outer side of the connecting sleeve 20. The knocking assembly includes a block 36 fixedly connected to the outer surface of the upper end of the connecting sleeve 20. The outer surface of the block 36 is arc-shaped. The number of the blocks 36 is several groups and they are distributed in a circular array. A collision block 42 is rotatably connected to the outer surface of the rotating shaft 39. The rotating shaft 39 is located at an eccentric position of the collision block 42.

[0031] By adopting the above technical solution, in order to further improve the filling and compaction degree of the foundry sand, a knocking component is provided. When the repressing component works, the rotating shaft 39 will make a circular motion along with the connecting plate 22. At this time, the rotating shaft 39 will drive the collision block 42 to move synchronously. When the collision block 42 contacts the stop block 36 on the surface of the connecting sleeve 20, it will push the collision block 42 to rotate with the rotating shaft 39 as the fulcrum. Since the collision block 42 is eccentrically arranged, when the center of gravity of the collision block 42 rotates to the uppermost side, the collision block 42 will flip with the rotating shaft 39 as the fulcrum under the action of gravity. Then the collision block 42 will collide and contact with the stop block 36. A certain vibration will be generated by the collision between the collision block 42 and the stop block 36. The vibration is transmitted to the foundry sand through the connecting sleeve 20 and the mold sleeve 27. The vibration can make the foundry sand fill more tightly, thereby further reducing the generation of voids in the foundry sand. It can not only improve the filling compaction degree of the foundry sand, but also help to improve the forming accuracy of the foundry sand and reduce the processing error.

[0032] Specifically, as Figure 4 shown in Figure 9 Figure, a sandblasting component is arranged inside the casting box 13 and the connecting sleeve 20. The sandblasting component includes a cavity 28 embedded and opened inside the connecting sleeve 20 and the casting box 13. The casting box 13 and the connecting sleeve 20 are fixedly connected by embedding a sandblasting hole 29. The sandblasting hole 29 is communicated with the inside of the cavity 28. An input pipe 21 is fixedly connected to the outside of the cavity 28. The input pipe 21 is communicated with the inside of the sand storage box. The number of the sandblasting holes 29 is several groups and they are distributed in a circular array.

[0033] The number of the support rods 12 is two groups and they are distributed in parallel. The retaining ring 26 is located outside the output shaft of the hydraulic rod 25. The input pipe 21 is made of an elastic material. The inside of the casting box 13 is filled with foundry sand. The gasket 23 is made of a hollow elastic material.

[0034] By adopting the above technical solution, in order to quickly fill and shape the foundry sand, a sandblasting component is provided. During operation, the foundry sand is pressurized and injected into the inside of the input pipe 21. The foundry sand enters the cavity 28 inside the casting box 13 and the connecting sleeve 20 under the action of pressure, and then is injected into the inside of the mold sleeve 27 and the casting box 13 through the sandblasting holes 29, so as to realize the rapid filling of the foundry sand, and the injection amount of the foundry sand can be flexibly controlled. Furthermore, the convenience and flexibility during the filling process of the foundry sand can be further improved, which helps to realize the stable transportation of the foundry sand.

[0035] Working principle: When processing the casting sand into a mold, the hydraulic rod 25 drives the die sleeve 27 to move downward. The die sleeve 27 will contact the upper side of the casting box 13 through the lower end of the module 18, so that the upper and lower ends of the module 18 are closely attached to the connecting sleeve 20 and the casting box 13 respectively. The casting sand enters the cavity 28 inside the casting box 13 and the connecting sleeve 20 under the action of pressure through the feeding pipe 21, and then is injected into the inside of the die sleeve 27 and the casting box 13 through the sand blasting holes 29, so as to realize the rapid filling of the casting sand. During the process that the connecting plate 22 drives the extrusion wheel 40 to make a circular motion, the extrusion wheel 40 will roll and contact the upper surface of the movable plate 30. Under the action of gravity, the extrusion wheel 40 will extrude the movable plate 30, and drive the extrusion plate 34 to extrude the casting sand inside the die sleeve 27 through the movable plate 30, so as to effectively improve the filling compactness of the casting sand. The rotating shaft 39 will drive the collision block 42 to move synchronously. The collision block 42 will flip with the rotating shaft 39 as the fulcrum under the action of gravity, and then the collision block 42 will collide and contact the stop block 36. A certain vibration will be generated by the collision between the collision block 42 and the stop block 36, and the casting sand can be filled more tightly through the vibration. Subsequently, the module 18 is taken out and the die sleeve 27 is pushed downward again by the hydraulic rod 25 to the upper side of the casting box 13, and then the reducer housing is cast between the die sleeve 27 and the casting box 13.
