Description

Technical Field

[0001] The invention relates to the technical field of casting equipment, in particular to a drum sand-falling machine. Background Art

[0002] In the foundry industry, the sand-falling process has always been a crucial link in the production process. The purpose of sand-falling is to effectively separate the casting from the molding sand to ensure the surface quality of the casting and the smooth progress of subsequent processing. Traditional sand-falling methods mainly include manual cleaning and simple mechanical vibration, but these methods have obvious limitations.

[0003] Traditional sand removal methods mostly use manual or simple mechanical vibration methods. These methods are not only inefficient, but also have safety hazards and environmental pollution. First, although manual cleaning is intuitive and easy to operate, it is inefficient and labor-intensive. Especially when dealing with a large number of castings, manual cleaning is not only time-consuming and labor-intensive, but also easy to damage the castings, affecting product quality. In addition, manual cleaning is difficult to ensure the cleanliness of the casting surface, and the residual molding sand may have an adverse effect on subsequent processing. Secondly, although the simple mechanical vibration method can improve the sand removal efficiency and reduce manual operation to a certain extent, its vibration effect is single, and it is difficult to comprehensively and thoroughly clean the molding sand on the casting surface. Especially for some castings with complex shapes, mechanical vibration often fails to achieve the expected effect, resulting in a large amount of molding sand remaining on the casting surface;

[0040] A plurality of sets of vibrating jet assemblies are arranged on the workbench 4 and are used to vibrate the plurality of movable rods 6 to separate the castings inside the plurality of movable rods 6 from the molding sand;

[0041] A driving assembly, which is disposed on the workbench 4 and is used to drive the fixing ring 8 to rotate;

The separated molding sand will fall to the top surface of the conveyor belt 42 through the sand dropping trough 22 for transmission, and flow out through the sand dropping outlet 43 to proceed to the next step.

[0044] As a preferred implementation in this embodiment, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Fig.11 As shown, the connecting member includes: a limit column 19, the limit column 19 is arranged on the connecting ring 5, one end of the movable rod 6 slides on the limit column 19, two springs 20 are arranged on the outer surface of the limit column 19, one of the springs 20 is in conflict with the bottom surface of the movable rod 6, and the other spring 20 is in conflict with the bottom surface of the movable rod 6, and a sliding groove 21 is opened on the side wall of the connecting ring 5, and the limit column 19, the spring 20 and one end of the movable rod 6 are all located in the sliding groove 21;

[0045] According to the above-mentioned features, multiple movable rods 6 can be evenly installed between the two connecting rings 5. Specifically, multiple sliding grooves 21 are arranged on the adjacent surfaces of the two connecting rings 5, and the limiting columns 19 are fixedly installed inside the multiple sliding grooves 21. The two ends of the movable rod 6 are respectively sleeved in the limiting columns 19 of the two connecting rings 5, so that the multiple movable rods 6 are evenly distributed between the two connecting rings 5, and the springs 20 arranged on the bottom and top surfaces of the two ends of the movable rod 6 can make the movable rod 6 swing up and down in the sliding groove 21 due to the elastic force of the spring 20.

[0046] As a preferred implementation in this embodiment, please refer to Figure 1 to Figure 5 As shown, the clamping member includes: two L-shaped fixing seats 29, the two L-shaped fixing seats 29 are fixedly mounted on the top surface of the workbench 4 and are symmetrically arranged, and the openings of the two L-shaped fixing seats 29 are fixedly mounted with clamp rings 30, the inner ring of the clamp ring 30 contacts the outer surface of the fixing ring 8 and fixes the fixing ring 8, and the side wall of the clamp ring 30 contacts the side wall of the driving ring 7;

[0047] According to the above-mentioned features, the sand-falling mechanism can be suspended above the workbench 4, and the two fixed rings 8 can be fixed. Specifically, because the driving rings 7 are fixedly installed on both sides of the two connecting rings 5, and the fixing rings 8 are fixedly installed on both sides of the two driving rings 7, when the clamping ring 30 clamps the fixing ring 8, the entire sand-falling mechanism will be clamped. Because the spring 20 does not contact the top surface of the workbench 4, the sand-falling mechanism clamped by the clamping ring 30 will be suspended above the workbench 4. At this time, the driving component only needs to drive one of the fixing rings 8 to rotate, so that the entire sand-falling mechanism can be rotated to separate the molding sand from the casting.

[0048] As a preferred implementation in this embodiment, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 , Fig. 9 and Fig.10As shown, the adsorption assembly includes: a fixed column 11, the fixed column 11 is fixedly mounted on the outer surface of the movable rod 6, a mounting column 12 is fixedly mounted on the bottom surface of the fixed column 11, a micro air pump 13 is fixedly mounted inside the mounting column 12, a negative pressure tube 14 is fixedly mounted on the bottom surface of the mounting column 12, an adsorption head 15 is fixedly mounted on the bottom surface of the negative pressure tube 14, a plurality of air suction ports 16 are opened on the bottom surface of the adsorption head 15, an air outlet pipe 17 and an air suction pipe 18 are arranged on the micro air suction pump 13, one end of the air outlet pipe 17 is connected to the top surface of the micro air suction pump 13, and the other end extends to the outside of the fixed column 11, one end of the air suction pipe 18 is connected to the bottom surface of the micro air suction pump 13, and the other end extends to communicate with the inside of the negative pressure tube 14;

[0049] According to the above features, the casting inside the movable rod 6 can be adsorbed and made to fall when it is rotated to a suitable position. Specifically, when the casting and the molding sand fall into the movable rod 6 through the inlet 10, the micro suction pump 13 inside the mounting column 12 works to evacuate the inside of the negative pressure tube 14 through the suction pipe 18, so that the inside of the negative pressure tube 14 forms a negative pressure state, and the suction head 15 is connected to the inside of the negative pressure tube 14, and the suction port 16 below the suction head 15 is also connected to the inside of the suction head 15, so at this time the suction port 16 will suck the casting into the movable rod 6. The micro air pump 13 is used for adsorption, and as the movable rod 6 rotates, the adsorption head 15 is continuously raised. At this time, the suction force of the micro air pump 13 is not enough to adsorb the casting, and the casting will fall due to its own gravity, so that it is separated from the molding sand for the first time. In addition, due to the different sizes of castings, large castings will fall more than small castings, so as to avoid damage to large castings due to falling too high. While the micro air pump 13 is working, part of the molding sand of the casting adsorbed will be discharged through the suction port 16, the adsorption head 15 and the negative pressure pipe 14 in sequence through the suction pipe 18 and the exhaust pipe 17.

[0050] As a preferred implementation in this embodiment, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the vibration jet assembly includes: a fixed plate 24, the fixed plate 24 is fixedly mounted on the bottom surface of the support rod 23, a plurality of protrusions 25 are fixedly mounted on the top surface of the fixed plate 24, the outer surface of the movable rod 6 is in contact with the protrusions 25, an extrusion jet 26 is arranged between the two protrusions 25, a pressing plate 27 is fixedly mounted on the top surface of the extrusion jet 26, a nozzle 28 is fixedly mounted on one side of the fixed plate 24, and the extrusion jet 26 is connected to the nozzle 28 through a hose;

[0051] According to the above-mentioned characteristics, the movable rod 6 can be vibrated to perform secondary separation of the casting and the molding sand inside the movable rod 6. Specifically, since the fixed plate 24 is fixedly installed on the support rod 23, and a plurality of protrusions 25 are installed on the fixed plate 24, when the movable rod 6 slides onto the protrusion 25, it will slide upward inside the slide groove 21, thereby squeezing and deforming the spring 20 on the movable rod 6. When the movable rod 6 moves to the empty groove on one side of the protrusion 25, the movable rod 6 will vibrate due to the rebound force of the spring 20. At this time, the movable rod 6 will press the pressure plate 27 downward to compress the air inside the extrusion jet 26 and spray it through the nozzle 28 to separate the molding sand on the casting inside the movable rod 6. The extrusion jet 26 is made of a material with resilience, so that after the movable rod 6 passes, the extrusion jet 26 will drive the pressure plate 27 to automatically rebound and absorb air, waiting for the next extrusion of the movable rod 6.

[0052] As a preferred implementation in this embodiment, please refer to Figure 1 to Figure 6 As shown, the driving assembly includes: a rotating column 31, the rotating column 31 is rotatably connected to the side wall of one of the L-shaped fixed seats 29, the side wall of the rotating column 31 is rotatably connected to a gear 32, a support block 33 is fixedly installed on the top surface of the workbench 4, a driving motor 34 is fixedly installed on the top surface of the support block 33, the output shaft of the driving motor 34 is connected to the side wall of the gear 32, a groove 35 is opened on the top surface of one of the fixing rings 8, and toothed belts 36 are evenly arranged inside the groove 35, and the toothed belts 36 are meshed with the gear 32;

[0053] According to the above features, the movable rod 6 can be rotated. Specifically, the staff turns on the drive motor 34 so that the output shaft of the drive motor 34 drives the gear 32 to rotate. Because the gear 32 is meshed with the toothed belt 36, when the gear 32 rotates, the toothed belt 36 drives the fixed ring 8 to rotate. When the fixed ring 8 rotates, the drive ring 7 connected to the fixed ring 8, the connecting ring 5 connected to the drive ring 7, and the movable rod 6 located between the two connecting rings 5 ​​will all rotate synchronously.

[0054] As a preferred implementation in this embodiment, please refer to Figure 2 and Figure 3 As shown, the lifting member includes: a hydraulic drive generator 37, which is fixedly mounted on the right side wall of the rectangular leg 1, and a plurality of mounting grooves 38 are provided on the top surface of the rectangular leg 1, and a hydraulic cylinder 39 is fixedly mounted inside each of the plurality of mounting grooves 38, and the output end of the hydraulic cylinder 39 is connected to the bottom surface of the triangular leg 2, and the top surface of the triangular leg 2 is rotatably connected to the bottom surface of the triangular leg 2 through a connecting column 40;

[0055] According to the above-mentioned features, the forward speed of the casting inside the movable rod 6 can be adjusted. Specifically, the hydraulic cylinder 39 is started to lift the base plate 3 connected to the output end of the hydraulic cylinder 39. The hydraulic drive generator 37 provides power for the hydraulic cylinder 39. At this time, because the top surface of the triangular leg 2 is rotatably connected to the bottom surface of the base plate 3 through the connecting column 40, when the right side of the base plate 3 is lifted, the left side of the base plate 3 will tilt downward along the inclined surface of the triangular leg 2, and no motion interference will be formed. When the forward speed of the casting needs to be accelerated, it is only necessary to raise the base plate 3. When the base plate 3 is lowered, the forward speed of the casting inside the movable rod 6 can be slowed down.

[0056] Working principle:

[0057] When in use, the casting and the molding sand are placed into the movable rod 6 through the inlet 10, and multiple movable rods 6 are installed between the two connecting rings 5 ​​through multiple groups of connecting parts. Driving rings 7 are fixedly installed on both sides of the connecting rings 5, and fixing rings 8 are fixedly installed on both sides of the two driving rings 7. The side walls of the two fixing rings 8 are respectively provided with an outlet 9 and an inlet 10. Multiple groups of adsorption components are respectively arranged on the multiple movable rods 6, and the adsorption components include a fixed column 11, an installation column 12, a micro suction pump 13, a negative pressure tube 14 and an adsorption head 15. When the casting and the molding sand fall into the movable rod 6, the micro suction pump 13 is started, and the inside of the negative pressure tube 14 is evacuated through the suction pipe 18 to form a negative pressure state, so that the suction port 16 of the suction head 15 adsorbs the casting. As the movable rod 6 rotates, the suction head 15 gradually rises. When the suction force is not enough to continue to adsorb the casting, the casting falls off from the movable rod 6 due to gravity, and the initial separation from the molding sand is achieved. Multiple groups of vibrating jet assemblies are arranged on the workbench 4, which are used to generate vibration and further separate the casting and the molding sand. The vibrating jet assembly includes a fixed plate 24, a protrusion 25, an extrusion jet 26, a pressure plate 27 and a nozzle 28. When the movable rod 6 rotates to the protrusion 25, the movable rod 6 slides upward under the action of the protrusion 25 and squeezes the spring 20. When the movable rod 6 moves over the protrusion 25, the spring 20 rebounds to cause the movable rod 6 to vibrate. At the same time, the movable rod 6 presses down the pressure plate 27 to squeeze The air inside the jet 26 is compressed and ejected through the nozzle 28 to further clean the molding sand on the casting. The driving component is arranged on the workbench 4, and is used to drive the fixed ring 8 to rotate. The driving component includes a rotating column 31, a gear 32, a support block 33, a driving motor 34, etc. After the driving motor 34 is started, the fixed ring 8 is driven to rotate through the meshing relationship between the gear 32 and the toothed belt 36, thereby rotating the entire sand falling mechanism to promote the separation process of the casting and the molding sand. The lifting component is arranged on the rectangular support leg 1, and is used to adjust the height of the triangular support leg 2, thereby affecting the forward speed of the casting in the movable rod 6. The lifting component includes a hydraulic drive generator 37, a hydraulic cylinder 39, etc. By adjusting the extension and contraction of the hydraulic cylinder 39, the inclination angle of the bottom plate 3 can be changed, thereby speeding up or slowing down the moving speed of the casting in the movable rod 6 to meet the separation requirements of castings of different sizes.

[0058] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
