Description

Technical Field

[0001] The invention belongs to the technical field of sand falling treatment, in particular to an automatic sand falling device for metal casting processing. Background Art

[0002] Metal casting refers to a processing method in which solid metal is melted into liquid and poured into a mold of a specific shape, and then it solidifies into the required shape. The subsequent operations of metal casting are inseparable from the sand shakeout machine, which is a casting equipment that uses vibration and impact to separate the molding sand and the casting in the mold. In order to process the surface of metal parts more conveniently, a sand shakeout processing device for metal casting is particularly needed.

[0003] A patent application with publication number CN117531984B discloses a sand-falling treatment device for metal casting processing. By setting a linkage part, the brush rod can be kept rotating while the casting can be intermittently driven to rotate a certain angle until the casting rotates one circle, thereby ensuring the blowing and brushing of various positions of the casting and ensuring the quality of the sand-falling treatment. Multiple actions are achieved through one drive, reducing the use of the driving source, and improving the continuity and smoothness of the processing, thereby improving the processing efficiency.

[0004] In the above-mentioned prior art, after the tubular metal casting is cast and formed, the casting sand inside the pipe is relatively difficult to clean. The prior art generally first vibrates the metal casting to remove the casting sand on the outside of the metal casting, and then uses a high-pressure water gun to clean the casting sand inside the tubular metal casting.

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0033] Example 1: Figure 1-Figure 5 、 Figure 9 As shown, an automatic sand-falling device for metal casting processing described in an embodiment of the present invention includes a clamping assembly, the clamping assembly includes two T-shaped bars 1 slidingly provided on the upper end of a first rectangular plate 4, and each T-shaped bar 1 is fixedly connected to an arc bar 11 on both sides and the upper end, and a cleaning assembly is respectively provided on the upper end and one side of the T-shaped bar 1, the cleaning assembly includes a brush 2 slidingly provided on the upper end and one side of the T-shaped bar 1, the brush 2 is rotatably provided on the upper end and one side of the T-shaped bar 1, the lower end of the first rectangular plate 4 is fixedly connected to the second rectangular plate 6 through a support column 42, a first rectangular hole 41 is opened on one side of the middle portion of the first rectangular plate 4, and a vibration assembly is provided at a position corresponding to the first rectangular hole 41 on the upper end of the second rectangular plate 6, the vibration assembly includes side plates 5 fixedly connected to both sides of the upper end of the second rectangular plate 6, and a number of cylindrical wheels 55 are slidably provided between the two side plates 5.

[0034] Specifically, in the prior art, after the tubular metal casting is cast and formed, the surface and interior of the metal casting need to be cleaned of the casting sand. Since the casting sand inside the pipe is difficult to clean, the prior art generally vibrates the metal casting first to remove the casting sand on the outside of the metal casting, and then uses a high-pressure water gun to clean the casting sand inside the tubular metal casting. The cleaning process is relatively cumbersome and inefficient. Moreover, since the casting sand cleaning often involves close-range operation, there are certain safety hazards when using a high-pressure water gun. When using the automatic sand falling device, the tubular metal casting is first placed between the two T-shaped bars 1, and then the two T-shaped bars 1 are driven to approach each other. The T-shaped bar 1 drives the arc bar 11 to clamp the tubular metal casting, and then the brush 2 on one side and the upper end of the T-shaped bar 1 is driven to rotate, and at the same time, the brush 2 is driven to extend into the pipe to rub the casting sand inside the pipe to make the casting sand fall off, and then the T-shaped bar 1 is driven to drive the tubular metal casting. The metal casting slides to the upper end of the first rectangular hole 41, and then drives the two T-shaped blocks to slide to the side away from the tubular metal casting, so that the tubular metal casting falls on the upper ends of the cylindrical wheels 55, and then drives the cylindrical wheels 55 to vibrate between the side plates 5, driving the tubular metal casting at the upper end to vibrate, so that the casting sand inside the tubular metal casting falls, and the sand removal process is completed on the inside and outside of the tubular metal casting, and then the tubular metal casting can be taken away, and the brush 2 is driven to penetrate deep into the inside of the tubular metal casting for friction, so that the casting sand inside falls off, and then the tubular metal casting is transferred to the upper end of the cylindrical wheel 55, and the cylindrical wheels 55 are driven to vibrate between the side plates 5, driving the tubular metal casting at the upper end to vibrate, so that the casting sand inside the tubular metal casting falls, and there is no need to use a high-pressure water gun to clean the casting sand inside the tubular metal casting. The sand removal process is automatically performed on the inside and outside of the tubular metal casting, thereby improving work efficiency and reducing safety hazards.

[0035] like Figure 2 As shown, one end of the first telescopic rod 12 is fixed to the opposite side of the T-shaped bar 1, and the first telescopic rod 12 is fixed to the end away from the T-shaped bar 1 with a first gear 121. The first gear 121 is fixed to the end away from the first telescopic rod 12 with a first slide 122. The first slide 122 is slidably arranged on the side of the first electric slide rail 123 away from the first gear 121. The first electric slide rail 123 is fixed to the upper end of the first rectangular plate 4 through the first support bar 127.

[0036] Specifically, by driving the first telescopic rod 12 to extend, the two T-shaped bars 1 are driven to approach each other to clamp the tubular metal casting. When the brush 2 is inserted into the tubular metal casting for friction, the first slide 122 is then driven to slide on one side of the first electric slide rail 123. The first slide 122 drives the tubular metal casting clamped between the T-shaped bars 1 to move to the upper end of the first rectangular hole 41 through the first telescopic rod 12. The first telescopic rod 12 is then driven to contract, causing the tubular metal casting to fall onto the upper end of the cylindrical wheel 55 for vibration treatment, so that all the casting sand inside and on the surface of the tubular metal casting falls off.

[0037] like Figure 2 As shown, a first rectangular block 124 is fixedly connected to the side of the first electric slide rail 123 away from the first gear 121, and a second gear 125 is rotatably provided on one side of the first rectangular block 124 corresponding to the position of the first gear 121. The second gear 125 is fixedly connected to the output end of the first motor 126 through a pin shaft, and the first motor 126 is fixedly connected to the upper end of the first rectangular plate 4 through a motor base.

[0038] Specifically, when the first slide 122 drives the tubular metal casting clamped between the T-shaped bars 1 to move to the upper end of the first rectangular hole 41 through the first telescopic rod 12, the first slide 122 drives the first gear 121 and the second gear 125 to be in a meshing state, and then the first motor 126 is started to drive the second gear 125 to rotate, and the second gear 125 drives the first gear 121 to rotate. The first gear 121 drives the tubular metal casting clamped between the T-shaped bars 1 to rotate through the first telescopic rod 12, causing the casting sand inside the tubular metal casting to fall, and then drives the first telescopic rod 12 to contract, causing the tubular metal casting to fall to the upper end of the cylindrical wheel 55.

[0039] like Figure 2 As shown, the two first telescopic rods 12 are respectively rotatably provided with the first rectangular bars 13 on the outer side near one end of the T-shaped bar 1, and the lower ends of the first rectangular bars 13 are respectively fixed with second slides 131, and the two second slides 131 are slidably provided on the upper ends of the second electric slide rails 132, and the lower ends of the second electric slide rails 132 are fixed with the third slide 133, and the third slide 133 is slidably provided on the upper ends of the third electric slide rails 134, and the third electric slide rails 134 are fixed to the upper end of the first rectangular plate 4.

[0040] Specifically, by driving the second slide 131, the first rectangular bar 13 is driven to approach each other on the second electric slide rail 132. The first rectangular bar 13 drives the T-shaped bar 1 to approach each other through the output end of the first telescopic rod 12 to clamp the tubular metal casting. When the first slide 122 drives the tubular metal casting clamped between the T-shaped bars 1 to move to the upper end of the first rectangular hole 41 through the first telescopic rod 12, the first rectangular bar 13 drives the third slide 133 to slide on the upper end of the third electric slide rail 134 through the second electric slide rail 132, and the first rectangular bar 13 supports the output end of the first telescopic rod 12.

[0041] like Figure 4 As shown, the cleaning assembly also includes a first cylindrical rod 21 fixed to the side of the brush 2 away from the T-shaped bar 1, the first cylindrical rod 21 is fixed with a second telescopic rod 23 at one end away from the brush 2, the second telescopic rod 23 is fixed with an output end of a second motor 24 at one end away from the first cylindrical rod 21, the second motor 24 is fixed to the upper end of the first rectangular plate 4 through a support plate 241, and a second rectangular block 22 is rotatably provided on the outside of the end of the first cylindrical rod 21 away from the brush 2, the upper end of the second rectangular block 22 is fixed with a U-shaped frame 221, and the lower end of the U-shaped frame 221 is respectively fixed with a fifth slide 224, and the fifth slide 224 is respectively slidably set on the upper end of the fifth electric slide rail 225, and the fifth electric slide rail 225 is fixed to the upper end of the first rectangular plate 4.

[0042] Specifically, the fifth slide 224 is driven to drive the U-shaped frame 221 to approach the side of the tubular metal casting close to the upper end of the fifth electric slide rail 225, and the U-shaped frame 221 drives the second telescopic rod 23 to extend through the second rectangular block 22, and at the same time drives the brush 2 to penetrate into the interior of the tubular metal casting through the first cylindrical rod 21. Then, the second motor 24 is started to drive the first cylindrical rod 21 to rotate through the second telescopic rod 23, and the first cylindrical rod 21 drives the brush 2 to rotate inside the tubular metal casting to rub and clean the casting sand inside the tubular metal casting.

[0043] like Figure 5 As shown, a waterproof cloth 3 is provided on one side of the upper end of the first rectangular hole 41 . The waterproof cloth 3 is located in the middle of the two first rectangular strips 13 and is tilted.

[0044] Specifically, when the brush 2 is inserted into the tubular metal casting and rotates and rubs, a small amount of casting sand will fall and fall on the upper end of the waterproof cloth 3 provided below. The surface of the waterproof cloth 3 is made of polyvinyl chloride material and the surface is relatively smooth. The waterproof cloth 3 is inclined toward the side of the first rectangular hole 41. After the casting sand falls on the upper end of the waterproof cloth 3, it can slide to the lower end between the two side plates 5 for unified collection.

[0045] like Figure 5As shown, the two ends of the waterproof cloth 3 are respectively fixed with second rectangular strips 31, and the two sides of the opposite end of the second rectangular strip 31 are respectively fixed with second cylindrical rods 32. A cylinder 33 is slidingly provided on the outside of the second cylindrical rod 32 away from the second rectangular strip 31. The second cylindrical rod 32 is fixed to the inside of the cylinder 33 through a first spring 34, and the end of the cylinder 33 away from the second cylindrical rod 32 is fixed to the upper end of the first rectangular plate 4 through a third support strip 35.

[0046] Specifically, when the first rectangular bar 13 is driven through the output end of the first telescopic rod 12 to drive the T-shaped bars 1 to move closer to each other and clamp the tubular metal casting, the second cylindrical rod 32 drives the second rectangular bar 31 to slide inside the cylinder 33 and squeezes the first spring 34, so that the second cylindrical rod 32 always rests on one side of the first rectangular bar 13, so that the width of the waterproof cloth 3 always follows the distance change between the first rectangular bars 13. The waterproof cloth 3 collects the fallen casting sand and then slides to the lower end between the two for unified collection.

[0047] Example 2: Figure 6-Figure 9 As shown, compared with Example 1, another embodiment of the present invention is: a second rectangular hole 51 is opened in the middle of the side panel 5, the second rectangular hole 51 is inclined, and a third rectangular bar 53 is slidably arranged inside the second rectangular hole 51, and the third rectangular bar 53 is arranged parallel to the oblique side of the second rectangular hole 51, and a plurality of cylindrical wheels 55 are rotatably arranged between the two third rectangular bars 53.

[0048] Specifically, when the tubular metal casting falls on the upper end of the cylindrical wheel 55, the third rectangular bar 53 is driven to slide up and down in the second rectangular hole 51, driving the cylindrical wheel 55 to vibrate, vibrating the tubular metal casting on the upper end of the cylindrical wheel 55, causing the casting sand to fall off.

[0049] like Figure 10 As shown, third cylindrical rods 54 are respectively fixed to the upper and lower ends of both sides of the third rectangular bar 53, and cylindrical holes 52 are respectively opened on the inner side of the second rectangular hole 51 at positions corresponding to the third cylindrical rods 54. The third cylindrical rod 54 is fixed to the inside of the cylindrical hole 52 through a second spring 541. The third rectangular bar 53 is fixed to the side away from the cylindrical wheel 55 with a third rectangular block 531. A cam 58 is rotatably provided on the upper end of the third rectangular block 531. The cam 58 is rotatably provided on one side of the side plate 5 through a pin shaft. The side of the cam 58 away from the side plate 5 is fixed to the output end of the third motor 581 through a pin shaft, and the third motor 581 is fixed to one side of the side plate 5 through a motor seat.

[0050] Specifically, by starting the third motor 581 to drive the cam 58 to rotate, the cam 58 drives the third rectangular block 531 to slide up and down, the third rectangular block 531 drives the third rectangular bar 53 to slide up and down, and the two third rectangular bars 53 drive the cylindrical wheel 55 between them to vibrate. At the same time, the third rectangular bar 53 drives the third cylindrical rod 54 to slide inside the cylindrical hole 52 and squeeze the second spring 541, vibrating the tubular metal casting at the upper end of the cylindrical wheel 55 to cause the casting sand to fall off.

[0051] like Figure 9 As shown, a collecting frame 56 is slidingly provided at the lower end between the two side panels 5 , and a conveyor belt 57 is provided at the lower end of the side panel 5 away from the first rectangular panel 4 , and the conveyor belt 57 is installed at the upper end of the second rectangular panel 6 .

[0052] Specifically, the cylindrical wheel 55 vibrates the tubular metal casting at the upper end, and the casting sand falls off and falls into the collection frame 56. The tubular metal casting slides to the side of the side plate 5 and falls on the upper end of the conveyor belt 57, and the cleaned tubular metal casting is transferred.

[0053] Working principle: During operation, the first rectangular bar 13 is driven to approach each other on the second electric slide rail 132 by driving the second slide 131. The first rectangular bar 13 drives the T-shaped bar 1 to approach each other through the output end of the first telescopic rod 12, thereby clamping the tubular metal casting. The U-shaped frame 221 is driven to approach the side of the tubular metal casting near the upper end of the fifth electric slide rail 225 by driving the fifth slide 224. The U-shaped frame 221 drives the second telescopic rod 23 to extend through the second rectangular block 22, while driving the brush 2 to penetrate into the interior of the tubular metal casting through the first cylindrical rod 21. Subsequently, the second motor 24 is started to drive the first cylindrical rod 21 to rotate through the second telescopic rod 23. The first cylindrical rod 21 drives the brush 2 to rotate inside the tubular metal casting, thereby rubbing and cleaning the casting sand inside the tubular metal casting.

[0054] When the brush 2 is inserted into the tubular metal casting and rotates and rubs, a small amount of casting sand will fall and fall on the upper end of the waterproof cloth 3 provided below. The surface of the waterproof cloth 3 is made of polyvinyl chloride material and has a relatively smooth surface. The waterproof cloth 3 is inclined toward the side of the first rectangular hole 41. After the casting sand falls on the upper end of the waterproof cloth 3, it can slide to the lower end between the two side plates 5 for unified collection.

[0055] Then, the first slide 122 is driven to slide on one side of the first electric slide rail 123, and the first slide 122 drives the tubular metal casting clamped between the T-shaped bars 1 to move to the upper end of the first rectangular hole 41 through the first telescopic rod 12, and then drives the first telescopic rod 12 to contract, so that the tubular metal casting falls on the upper end of the cylindrical wheel 55, and then starts the third motor 581 to drive the cam 58 to rotate, and the cam 58 drives the third rectangular block 531 to slide up and down, and the third rectangular block 531 drives the third rectangular bar 53 to slide up and down, and the cylindrical wheel 55 between the two third rectangular bars 53 vibrates. At the same time, the third rectangular bar 53 drives the third cylindrical rod 54 to slide inside the cylindrical hole 52 and squeeze the second spring 541, vibrating the tubular metal casting at the upper end of the cylindrical wheel 55, causing the casting sand to fall off, and the casting sand falls into the collection frame 56, and the tubular metal casting slides to one side of the side plate 5 and falls on the upper end of the conveyor belt 57, and the cleaned tubular metal casting is transferred.
