Description

Technical Field

[0001] The invention belongs to the technical field of casting riser grinding, in particular to a casting riser grinding device. Background Art

[0002] The riser used in casting is a cavity specially set up in the mold to store molten metal. It is mainly used to compensate for the shrinkage that may occur during the casting process. It plays a role in preventing shrinkage holes, shrinkage, exhaust and slag collection. After the casting of flange castings is completed, the riser needs to be cut off. Since the outer circumference of the flange is an arc shape, it is difficult for the riser to fit the arc surface for cutting. Therefore, it is necessary to ensure the cutting and grinding effects of the flange riser.

[0003] A patent with publication number CN117140284B discloses a casting grinding processing device and a method of using the same, including a base plate, the roller being a hollow structure, and a driving mechanism being provided between the support shaft and the roller; the present invention drives the friction belt to rotate through a transmission component, so that the friction belt rotates through a friction disk, so that the friction disk drives the positioning tube to rotate, so that the flange casting placed on the positioning tube can continue to rotate, so that the riser of the flange casting can be gradually and completely polished by the closed-loop polishing belt, which can effectively avoid the phenomenon that the riser of the flange casting and the polishing mechanism are stuck, and ensure the continuity of the polishing of the riser of the flange casting.

[0004] Since the riser of a casting protrudes for a long part, when grinding the riser of a casting, a cutting device is used to cut off the riser first and then grind it; when cutting the riser, the casting needs to be fixed and rotated a circle, and then the riser of the casting is cut with a cutting knife or other cutting equipment, and then the riser position of the flange casting is grinded after cutting. The efficiency of cutting and grinding the riser of a casting is low, and when the riser is cut by a cutting knife or other equipment, the cut riser may fly away, causing harm to workers and equipment.

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0030] like Figures 1 to 5As shown, a casting riser grinding device described in an embodiment of the present invention includes a conveyor table 1, a conveyor belt 6 is provided in the conveyor table 1, a cutting machine 2 is provided on one side of the conveyor table 1, a cutting head 13 is provided on one side of the cutting machine 2, a grinder 3 is provided on one side of the conveyor table 1, a grinding wheel 7 is provided on one side of the grinder 3, and the grinding wheel 7 is used to grind the side of a disc body 17, a plurality of rotating devices are provided on the conveyor belt 6, and the plurality of rotating devices can rotate the disc body 17 to grind the riser, and the rotating device includes a fixed cylinder 16 fixedly connected to the conveyor belt 6, and a connecting disc 15 is rotatably connected to one side of the fixed cylinder 16, and the connecting disc 15 is connected to the fixing cylinder 16. A connecting plate 12 is fixedly connected to one side of the disk 15, a clamping frame 33 is fixedly connected to one end of the connecting plate 12, a connecting rod 31 is slidably connected to one side of the clamping frame 33, the connecting rod 31 is clamped with the fixed cylinder 16, the connecting rod 31 can slide on one side of the fixed cylinder 16, a first motor 19 is fixedly connected to the fixed cylinder 16, a rotating cylinder 18 is fixedly connected to the output end of the first motor 19, a clamping device is provided in the rotating cylinder 18, the clamping device is used to clamp the disk body 17, a push block 38 is slidably connected to the clamping frame 33, one side of the push block 38 is fixedly connected to one end of the first spring 39, and the other end of the first spring 39 is fixedly connected to the clamping frame 33.

[0031] Specifically, at present, when pouring castings, a riser is usually left on the casting, and the riser needs to be cut and polished to obtain the required casting. When polishing the riser of the casting, the casting is usually fixed, and the fixed casting is rotated and polished with a polishing belt or other polishing equipment. Since the riser of the casting protrudes for a long part, when polishing the riser of the casting, a cutting device is used to cut off the riser first and then polish it. When cutting the riser, the casting needs to be fixed and rotated for a circle, and then the riser of the casting is cut with a cutting knife or other cutting equipment, and then the riser position of the cut flange casting is polished. The efficiency of cutting and polishing the riser of the casting is low, and when the riser is cut by a cutting knife or other equipment, the cut riser will fly away, causing harm to workers and equipment.

[0032] In this embodiment, the disc body 17 is a flange casting, and the protrusion 44 is the flange casting riser. When grinding the casting protrusion 44, the disc body 17 is first placed on the rotating device on the conveyor belt 6, and the disc body 17 is clamped by the clamping device and fixed on the rotating device, and the disc body 17 is transported to one side of the cutting machine 2 through the conveyor belt 6, and the protrusion 44 on one side of the disc body 17 is cut by the cutting head 13. In the process of transporting the disc body 17, the first motor 19 is started to drive the rotating cylinder 18 to rotate so that the clamping device rotates with the disc body 17, and the protrusion 44 of the disc body 17 is rotated into the clamping frame 33, so that the protrusion 44 on one side of the disc body 17 can be stopped at the specified position and cut and polished by the cutting head 13. The disc body 17 pushes the push block 38 to slide in the clamping frame 33 with the protrusion 44 and compresses the first spring 39. When the push block 38 moves to press the connecting rod 31, the connecting rod 31 is no longer clamped with the fixed cylinder 16. The connecting rod 31 can slide on the fixed cylinder 16, and the disc body 17 rotates through the protrusion 44 to rotate with the card frame 33, and the protrusion 44 of the disc body 17 can be cut by the cutting machine 2 and the cutting head 13. After the cutting of the protrusion 44 is completed, the first spring 39 recovers its deformation and generates elastic force to pop the protrusion 44 out of the card frame 33 for collection; by placing the protrusion 44 on the disc body 17 in the card frame 33 for cutting processing, and after the protrusion 44 is cut, the protrusion 44 is pushed out of the card frame 33 for recovery, the protrusion 44 can be positioned, so that the protrusion 44 is fixed in a fixed position for cutting work, and there is no need to rotate the disc body 17 once to cut the protrusion 44 during cutting, which speeds up the efficiency of cutting and polishing the protrusion 44 of the casting, and makes the protrusion 44 stay in the card frame 33, to prevent the protrusion 44 from flying when cutting the protrusion 44, thereby ensuring the safety of cutting and polishing the protrusion 44 of the casting.

[0033] like Figures 1 to 5 As shown, a first slot 43 is provided on one side of the fixed cylinder 16, and the first slot 43 is a T-shaped slot. The connecting rod 31 is connected to the fixed cylinder 16 through the first slot 43, and the connecting rod 31 can slide in the first slot 43. The connecting rod 31 is located in the card frame 33 and a second slot 40 is provided on one side. A sliding column 41 is fixedly connected to one side of the card frame 33, and a second spring 42 is sleeved on the sliding column 41. One end of the second spring 42 is fixedly connected to the card frame 33, and the other end of the second spring 42 is fixedly connected to the connecting rod 31. One side of the push block 38 can slide into the second slot 40.

[0034] Specifically, when cutting and grinding the casting, the protrusion 44 pushes the push block 38 to move in the frame 33 so that the push block 38 presses the connecting rod 31 and slides into the second slot 40. Since one side of the second slot 40 is arranged in an arc shape, and since the first slot 43 is composed of a vertical section slide groove and an arc-shaped slide groove, when the push block 38 moves into the second slot 40, the connecting rod 31 will move upward and slide out of the vertical section slide groove of the first slot 43, so that the connecting rod 31 slides into the arc-shaped groove of the first slot 43. At this time, the disk body 17 rotates with the protrusion 44, so that the frame 33 can rotate with the connecting rod 31 around the fixed tube 16, and the protrusion 44 and the disk body 17 are cut and separated by the cutting head 13.

[0035] like Figures 1 to 5 As shown, a slider 32 is slidably connected to one side of the card frame 33, a fixing column 35 is fixedly connected inside the card frame 33, one side of the slider 32 is slidably connected to the fixing column 35, a third spring 36 is sleeved on the fixing column 35, one end of the third spring 36 is fixedly connected to the card frame 33, and the other end of the third spring 36 is fixedly connected to the slider 32.

[0036] Specifically, when the protrusion 44 moves into the card frame 33, it will first press the slider 32 to move the slider 32 upward and press the second spring 42 through the sliding column 41. When the protrusion 44 moves completely into the card frame 33, the second spring 42 recovers its deformation to make the slider 32 move downward to block the entrance of the card frame 33, so that the protrusion 44 will not fly out of the card frame 33 during the cutting process.

[0037] like Figures 1 to 5 As shown, a limiting column 37 is fixedly connected to one side of the slider 32 , a third slot 34 is defined on one side of the slider 32 , and a protrusion 14 is fixedly connected to one side of the cutting head 13 , and the protrusion 14 can slide into the third slot 34 .

[0038] Specifically, when cutting the protrusion 44, the limit column 37 prevents the slider 32 from moving downward too much and blocking the movement of the protrusion 44 in the frame 33. The disk body 17 will rotate with the frame 33 to make the slider 32 rotate toward the cutting head 13, so that the protrusion 14 is stuck in the third slot 34 in the slider 32. Since one side of the third slot 34 is set to be arc-shaped, when the protrusion 14 presses the arc surface of the third slot 34, the slider 32 will move upward and no longer block the entrance of the frame 33. At this time, the first spring 39 recovers its deformation and pushes the protrusion 44 in the frame 33 out for collection.

[0039] like Figures 1 to 5 As shown, the clamping device includes a second motor 20 fixedly connected in the rotating cylinder 18, and a rotating disk 21 is fixedly connected to the output end of the second motor 20. A plurality of limiting grooves 24 are opened in the rotating disk 21. A plurality of support frames 22 are slidably connected in the rotating cylinder 18, and one side of the plurality of support frames 22 is slidably connected to the limiting grooves 24. The plurality of support frames 22 are used to clamp the disk body 17.

[0040] Specifically, the second motor 20 is started to rotate the rotating disk 21, and the rotation of the rotating disk 21 causes the support frame 22 to slide in the rotating cylinder 18 through the limit groove 24, so that the support frame 22 moves the clamping disk body 17 and places the disk body 17 in the center of the clamping device, which is convenient for the subsequent cutting of the protrusion 44 and the grinding of the surface of the disk body 17.

[0041] like Figures 1 to 5 As shown, a grinding frame 4 is provided on one side of the conveying platform 1 , and two grinding plates 8 are provided on one side of the grinding frame 4 . A gap matching the disc body 17 is provided between the two grinding plates 8 , and the upper and lower surfaces of the disc body 17 are ground by the two grinding plates 8 .

[0042] Specifically, when the conveyor belt 6 moves the disc 17 to one side of the grinding sheet 8 , the disc 17 will move between the two grinding sheets 8 . At this time, the disc 17 continues to rotate to cooperate with the rotation of the grinding sheets 8 to grind the upper and lower surfaces of the disc 17 .

[0043] like Figures 1 to 5 As shown, a plurality of rotating blocks 28 are rotatably connected to one side of the rotating cylinder 18 , one end of each of the rotating blocks 28 is fixedly connected to one end of a first torsion spring 29 , and the other ends of each of the first torsion springs 29 are fixedly connected to the rotating cylinder 18 .

[0044] Specifically, when the disc 17 is placed on the rotating device, the rotating block 28 is initially in an open state rather than in the rotating cylinder 18 , so that the disc 17 can be placed on the rotating block 28 and clamped and fixed by the support frame 22 .

[0045] like Figures 1 to 5 As shown, a plurality of blocks 27 are slidably connected to one side of the rotating cylinder 18, a plurality of fixing rods 25 are fixedly connected to one side of the rotating cylinder 18, a fourth spring 26 is sleeved on one side of the plurality of fixing rods 25, one end of the plurality of fourth springs 26 is fixedly connected to the block 27, and the other end of the plurality of fourth springs 26 is fixedly connected to the rotating cylinder 18, a plurality of blocks 30 are fixedly connected to one side of the rotating disk 21, and the plurality of blocks 30 can be engaged with the corresponding blocks 27.

[0046] Specifically, when grinding the upper and lower surfaces of the disc body 17, the grinding sheet 8 will press the rotating block 28 to make the rotating block 28 rotate through the first torsion spring 29. The rotation of the first torsion spring 29 will depress the card block 27 to make the card block 27 slide in the rotating cylinder 18, so that the fourth spring 26 is compressed and then rebounded through the fixing rod 25, and the rotating block 28 is fixed in the rotating cylinder 18 through the card block 27. When the disc body 17 is finished grinding, the second motor 20 is started to drive the rotating disc 21 to reverse so that the support frame 22 is retracted and no longer clamps the disc body 17. The rotating disc 21 reverses and moves with the stop block 30 to push the card block 27 to move and cancel the obstruction of the rotating block 28. Under the action of the first torsion spring 29, the rotating block 28 slides out of the rotating cylinder 18 and is in an open state, so that the subsequent disc body 17 can be placed on the rotating block 28 again. Embodiment 2

[0047] like Figures 3 to 7 As shown in Comparative Example 1, another embodiment of the present invention is:

[0048] A friction pad 23 is fixedly connected to one side of each of the supporting frames 22 .

[0049] Specifically, when the disc body 17 is clamped by the support frame 22 , the disc body 17 can be better fixed and clamped by the friction pad 23 that has undergone friction treatment.

[0050] like Figure 4 As shown, two fixed brushes 9 are fixedly connected to one side of the conveying platform 1, and one side of the two fixed brushes 9 is rotatably connected to a rotating brush 10. The two fixed brushes 9 are connected to the rotating brush 10 through a second torsion spring 11, and a collecting plate 5 is fixedly connected to one side of the conveying platform 1.

[0051] Specifically, the fixed brush 9 is used to clean the waste residue generated by the cutting protrusion 44 on the surface of the conveyor belt 6. When the rotating device passes through the fixed brush 9, it will push the rotating brush 10, so that the rotating brush 10 rotates in the fixed brush 9 through the second torsion spring 11, so that the rotating device can pass smoothly and the rotating brush 10 will return to its original state. Figure 7 The waste residue on the conveyor belt 6 is cleaned. When the conveyor belt 6 brings the disc 17 to the lower side of the conveyor platform 1, the clamping device releases the disc 17, so that the disc 17 and the protrusion 44 slide out of the conveyor platform 1 from the collecting plate 5 for collection.

[0052] Working principle: In this embodiment, when grinding the protrusion 44 of the casting, the disc 17 is first placed on the rotating device on the conveyor belt 6, the disc 17 is clamped by the clamping device and fixed on the rotating device, and the disc 17 is transported to one side of the cutting machine 2 by the conveyor belt 6, and the protrusion 44 on one side of the disc 17 is cut by the cutting head 13. In the process of transporting the disc 17, the first motor 19 is started to drive the rotating cylinder 18 to rotate so that the clamping device rotates with the disc 17, and the protrusion 44 on one side of the disc 17 is rotated into the clamping frame 33, so that the protrusion 44 on one side of the disc 17 can be stopped at the specified position and cut and polished by the cutting head 13. The disc 17 pushes the push block 38 with the protrusion 44 to slide in the clamping frame 33 and compress the first spring 39. When the push block 38 moves to press the connecting rod 31, the connecting rod 31 is no longer clamped with the fixed cylinder 16, so that the connecting rod 31 can slide on the fixed cylinder 16, and the disc 17 rotates through the protrusion 44 rotates with the card frame 33, and the protrusion 44 of the disc body 17 can be cut by the cutting machine 2 and the cutting head 13. After the protrusion 44 is cut, the first spring 39 recovers its deformation and generates elastic force to eject the protrusion 44 from the card frame 33 for collection. When cutting and polishing the casting, the protrusion 44 pushes the push block 38 to move in the card frame 33 so that the push block 38 presses the connecting rod 31 and slides into the second card slot 40. Since one side of the second card slot 40 is set in an arc shape, The first slot 43 is composed of a vertical slot and an arc slot. When the push block 38 moves into the second slot 40, the connecting rod 31 moves upward and slides out of the vertical slot of the first slot 43, and slides into the arc slot of the first slot 43. At this time, the disc 17 rotates with the protrusion 44, so that the card frame 33 and the connecting rod 31 rotate around the fixed cylinder 16, and the protrusion 44 and the disc 17 are cut and separated by the cutting head 13.

[0053] When the protrusion 44 moves into the card frame 33, it will first press the slider 32 to make the slider 32 move upward and press the second spring 42 through the sliding column 41. When the protrusion 44 is completely moved into the card frame 33, the second spring 42 recovers its deformation to make the slider 32 move downward to block the entrance of the card frame 33, so that the protrusion 44 will not fly out of the card frame 33 during the cutting process; when cutting the protrusion 44, the limit column 37 prevents the slider 32 from moving too much downward to block the movement of the protrusion 44 in the card frame 33. The disk body 17 will rotate with the card frame 33 to make the slider 32 rotate toward the direction of the cutting head 13, so that the protrusion 14 is stuck in the third card slot 34 in the slider 32. Since one side of the third card slot 34 is set to an arc shape, when the protrusion 14 presses the arc surface of the third card slot 34, the slider 32 will move upward and no longer block the entrance of the card frame 33. At this time The first spring 39 restores its deformation to push out the protrusion 44 in the card frame 33 for collection; the rotating disk 21 is rotated by starting the second motor 20, and the rotating disk 21 rotates to make the support frame 22 slide in the rotating cylinder 18 through the limit groove 24, so that the support frame 22 moves to clamp the disk body 17 and makes the disk body 17 in the center of the clamping device, which is convenient for the subsequent cutting of the protrusion 44 and the grinding of the surface of the disk body 17; when the conveyor belt 6 moves the disk body 17 to one side of the grinding sheet 8, the disk body 17 will move between the two grinding sheets 8, and at this time the disk body 17 continues to rotate to cooperate with the rotation of the grinding sheet 8 to grind the upper and lower surfaces of the disk body 17; when the disk body 17 is placed on the rotating device, the initial state of the rotating block 28 is not in the rotating cylinder 18 but in the open state, so that the disk body 17 can be placed on the rotating block 28 and clamped and fixed by the support frame 22;

[0054] When the upper and lower surfaces of the disc body 17 are polished, the polishing sheet 8 will press the rotating block 28 to make the rotating block 28 rotate through the first torsion spring 29. The rotation of the first torsion spring 29 will depress the card block 27 to make the card block 27 slide in the rotating cylinder 18, so that the fourth spring 26 is compressed and then rebounded through the fixing rod 25, and the rotating block 28 is fixed in the rotating cylinder 18 through the card block 27. When the disc body 17 is polished, the second motor 20 is started to drive the rotating disc 21 to reverse so that the support frame 22 is retracted and no longer clamps the disc body 17. The rotating disc 21 reverses and moves with the stopper 30 to push the card block 27 to move and cancel the obstruction to the rotating block 28. Under the action of the first torsion spring 29, the rotating block 28 slides out of the rotating cylinder 18 When the disc 17 is in an open state, the subsequent disc 17 can be placed on the rotating block 28 again; when the disc 17 is clamped by the support frame 22, the friction pad 23 treated with friction can better fix the clamped disc 17. When the conveyor belt 6 brings the disc 17 to the lower side of the conveyor platform 1, the clamping device releases the disc 17, so that the disc 17 and the protrusion 44 slide out of the conveyor platform 1 from the collecting plate 5 for collection; the waste residue generated by the cutting protrusion 44 on the surface of the conveyor belt 6 is cleaned by the fixed brush 9. When the rotating device passes through the fixed brush 9, it pushes the rotating brush 10, so that the rotating brush 10 rotates in the fixed brush 9 through the second torsion spring 11, so that the rotating device can pass smoothly and the rotating brush 10 will return to the original state. Figure 7 The waste residue on the state cleaning conveyor belt 6.
