Description

Technical Field

[0001] The embodiments of this disclosure relate to the field of metal casting technology, and more specifically, to a high-efficiency impurity removal centrifuge for metal castings. Background Technology

[0002] A centrifuge is a casting method in which molten metal is poured into a rotating mold, and under the action of centrifugal force, it fills the mold and solidifies into a casting. The machine used for centrifugal casting is called a centrifugal casting machine.

[0003] In existing centrifuges, molten steel is poured into a transmission frame, then through a transmission pipe into a rotating mold. The rotating mold then distributes the molten steel evenly inside. However, after the molten steel cools, impurities accumulated due to centrifugal force remain on the inner wall of the casting, requiring operators to re-grind the inner wall of the casting.

[0004] The centrifuges described above have reduced effectiveness because operators have difficulty cleaning the impurities accumulated on the inner walls of the castings, resulting in a significant amount of subsequent processing time for the operators. Utility Model Content

[0005] To overcome the above-mentioned defects, embodiments of this disclosure provide a high-efficiency impurity removal centrifuge for metal castings, which solves the technical problem in the prior art that it is difficult for operators to clean impurities accumulated on the inner wall of castings, resulting in a large amount of subsequent processing time for operators.

[0025] like Figures 1-4 As shown, it illustrates a high-efficiency impurity removal centrifuge for metal castings according to an embodiment of the present disclosure, which includes a first fixed frame 1 and a second fixed frame 14, and also includes a connecting frame 2, an adjusting frame 3, an adjusting column 4, an adjusting pin 5, an adjusting block 6, a moving frame 7, an insert block 8, a grinding plate 9, a connecting block 10 and an auxiliary mechanism. like Figure 3As shown, the connecting frame 2 is installed on the side of the first fixed frame 1. An adjusting frame 3 is installed on the upper surface of the connecting frame 2. An adjusting column 4 is slidably connected inside the adjusting frame 3. An adjusting pin 5 is threaded through the side of the adjusting frame 3. One end of the adjusting pin 5, which is threaded through the adjusting frame 3, abuts against the adjusting column 4. An adjusting block 6 is installed on the upper surface of the adjusting column 4. A movable frame 7 is slidably connected to the outer side of the adjusting block 6. A plug-in block 8 is slidably connected inside the movable frame 7. A grinding plate 9 is installed on the upper surface of the plug-in block 8. The grinding plate 9 is a fine grinding stone plate that can withstand high temperatures. A connecting block 10 is slidably connected inside the movable frame 7. Both the connecting block 10 and the adjusting block 6 are T-shaped sliders. The surface of the connecting block 10 is relatively rough. Therefore, after the connecting block 10 slides into the movable frame 7, it will not slip off with the movement of the movable frame 7. An auxiliary mechanism is provided inside the connecting block 10.

[0026] like Figure 4 As shown, the auxiliary mechanism includes a placement rod 11, a placement plate 12, and a counterweight 13. The placement rod 11 is threaded through the inside of the connecting block 10. The placement plate 12 is installed at the bottom end of the placement rod 11. The counterweight 13 is sleeved on the outer surface of the placement rod 11. The number of counterweights 13 can be adjusted according to the distance the moving frame 7 moves.

[0027] like Figure 2 As shown, a transmission rod 15 is rotatably connected inside the first fixed frame 1 and the second fixed frame 14. A transmission wheel 16 is installed on the outer surface of the transmission rod 15. Reinforcing plates are installed on the upper surfaces of both the first fixed frame 1 and the second fixed frame 14. A transmission motor 17 is installed inside the first fixed frame 1. The output end of the transmission motor 17 passes through the interior of the first fixed frame 1. There are two sets of transmission motors 17. The transmission motors 17 require an external single-control switch to start and stop. The transmission motors 17 require an external power supply. An auxiliary rod 18 is installed on both the output end of the transmission motor 17 and the outer end of the transmission rod 15. The outer surface of the auxiliary rod 18 is connected to the transmission wheel 16 via a belt 19. A pulley 20 is dynamically connected, and a casting roller 21 is rolledly connected to the outer surface of the transmission wheel 16. A connecting groove is opened on the outer surface of the casting roller 21, and the width of the connecting groove is adapted to the width of the transmission wheel 16. A blocking ring 22 is inserted inside the casting roller 21. A fixing pin 23 is threaded through the outer surface of the casting roller 21. One end of the fixing pin 23, which is threaded through the casting roller 21, is threaded inside the blocking ring 22. The blocking ring 22 can be replaced and adjusted according to the thickness of the casting. A support frame 24 is installed on the outer side of the second fixed frame 14. A feed frame 25 is installed on the upper surface of the support frame 24. A feed pipe 26 is connected to the side of the feed frame 25.

[0028] In this embodiment, the manipulator ring 22 slides along the casting drum 21, the manipulator pin 23 passes through the casting drum 21 and inserts into the manipulator ring 22, and then the manipulator pin 23 is rotated clockwise to fix the manipulator ring 22 in the casting drum 21. Molten steel is poured into the feed frame 25, allowing it to pass through the feed frame 25 and enter the casting drum 21 via the feed pipe 26. The drive motor 17 is started, and the drive motor 17 drives the pulley 20 to rotate via the belt 19. The rotation of the pulley 20 drives the auxiliary rod 18 to rotate, and the rotation of the auxiliary rod 18 at the top drives the drive rod 15 to rotate. The drive rod 15 rotates along the inside of the first fixed frame 1 and the second fixed frame 14, and the rotation of the drive rod 15 drives the casting drum 21 to rotate. The rotation of the casting drum 21 drives the molten steel inside to rotate, generating centrifugal force inside the casting drum 21. This causes the molten steel to adhere tightly to the inner wall of the casting drum 21. Impurities in the molten steel move evenly inward with the molten steel casting, causing the impurities to be freed on the inner wall of the casting. The molten steel gradually cools and forms the casting. After the casting temperature drops for a period of time, the grinding plate 9 is moved to the upper left side of the moving frame 7. The grinding plate 9 is moved downward to drive the insertion block 8 downward. The insertion block 8 slides down along the moving frame 7, so that the lower surface of the grinding plate 9 contacts the upper surface of the moving frame 7. Multiple sets of counterweights 13 are placed on the upper surface of the placement plate 12 along the placement rod 11. The placement rod 11 is inserted into the connecting block 10 and the placement rod 11 is tightened clockwise. The connecting block 10 is slid down along the moving frame 7, so that the counterweights 13 are located on the lower right side of the moving frame 7. Manipulating the counterweight 13 to move to the left causes the placement rod 11 to move to the left. The placement rod 11 moves to the left, causing the placement plate 12 to move to the left. The placement rod 11 moves to the left, causing the connecting block 10 to move to the left. Due to the large friction, the connecting block 10 causes the moving frame 7 to move to the left. The moving frame 7 moves to the left along the adjusting block 6. The moving frame 7 moves to the left, causing the insertion block 8 to move to the left. The insertion block 8 moves to the left, causing the grinding plate 9 to move to the left. The grinding plate 9 moves to the left and extends into the casting cylinder 21. At this time, the grinding plate 9 is located on the rightmost side inside the casting cylinder 21. Loosen the adjusting pin 5 counterclockwise, and move the adjusting column 4 upward along the inside of the adjusting frame 3. The upward movement of the adjusting column 4 causes the adjusting block 6 to move upward, the upward movement of the adjusting block 6 causes the moving frame 7 to move upward, the upward movement of the moving frame 7 causes the connecting block 10 to move upward, the upward movement of the connecting block 10 causes the placement rod 11 to move upward, the upward movement of the placement rod 11 causes the placement piece 12 to move upward, the upward movement of the placement piece 12 causes the counterweight block 13 to move upward, the upward movement of the moving frame 7 causes the insertion block 8 to move upward, the upward movement of the insertion block 8 causes the grinding plate 9 to move upward, the upward movement of the grinding plate 9 contacts the inner wall of the casting, and then tighten the adjusting pin 5 clockwise to press against the adjusting column 4. Manipulate the moving frame 7 to move to the right along the adjusting block 6. The movement of the moving frame 7 to the right drives the insertion block 8 to move to the right. The movement of the insertion block 8 to the right drives the grinding plate 9 to move to the right. The inner wall of the casting is ground by the rotation of the casting drum 21. After the grinding is completed, loosen the fixing pin 23 counterclockwise and remove the blocking ring 22 from the casting drum 21. Then, the casting is removed from the inside of the casting drum 21 by the external clamping equipment.
