Description

Technical Field

[0001] The present application relates to the technical field of magnesium ingot cutting, and in particular to a gas-protected magnesium ingot cutting device. Background Art

[0002] When preparing magnesium powder, it is necessary to first cut a magnesium ingot made of metallic magnesium to break the cut magnesium ingot into metallic magnesium debris, and then pass the magnesium ingot debris into a ball mill or vibration mill and other equipment to grind the magnesium ingot debris and grinding media together, so that the magnesium ingot casting is broken into powder by the debris.

[0003] Referring to the Chinese patent application document with publication number CN116689768A, the subject name is a gas-shielded metal ingot cutting device. The device is provided with a gas shield. By flushing a shielding gas into the gas shield, the metal ingot is prevented from contacting with the air, causing an oxidation reaction and affecting the purity. At the same time, it can prevent the temperature of the cutting blade from being too high during cutting, causing the cut chips to contact with the air and cause explosion and combustion.

[0004] According to the above technical scheme, in the process of cutting magnesium ingots, it is first necessary to accurately transport the magnesium ingots to the cutting station. Due to the limitation of the size of the working space, there are certain operating difficulties in the loading process of the magnesium ingots. After the loading is completed, in order to ensure the safety of the cutting process and the quality of the magnesium ingots, the air inside the gas protective cover needs to be replaced. During the air replacement process, the operator needs to closely observe the oxygen concentration inside the gas protective cover to ensure that it meets the safety standards. After the loading is completed, in order to further ensure the safety of the cutting process, the internal gas needs to be replaced again, and the gas is replaced with an inert gas before cutting. In this process, a large amount of gas in the cutting station needs to be replaced before the magnesium ingot can be cut, which affects the production efficiency. Summary of the invention

[0005] In view of this, the present application provides a gas-protected magnesium ingot cutting device, which aims to solve the problem of requiring a large amount of replacement of the gas in the cutting station when cutting the magnesium ingot.

[0006] A gas-shielded magnesium ingot cutting device provided in the present application adopts the following technical scheme, including a cutting frame, a pushing mechanism and a cutting mechanism arranged on the cutting frame; a feeding mechanism is arranged on the cutting frame, and the feeding mechanism is used to drive the magnesium ingot to move upward toward the cutting mechanism; a cutting opening is opened on the cutting frame, and a pushing top plate is slidably connected to the cutting frame, and the pushing top plate is arranged at the cutting opening. After the pushing top plate moves, it abuts against the side wall of the magnesium ingot adjacent to the magnesium ingot being cut, and a pushing spring is fixedly connected to the side wall of the pushing top plate, and the pushing spring is used to push the pushing top plate to move toward the magnesium ingot.

[0007] When cutting the magnesium ingot, the magnesium ingot located below the cutting station will keep the upper part of the cutting edge sealed, reducing the consumption of inert gas during the cutting process, thereby reducing production costs, and at the same time being able to reduce oxidation during the cutting process of the magnesium ingot through a closed state.

[0008] Optionally, the loading mechanism includes a loading push plate slidably connected to the cutting frame, the side wall of the cutting frame is fixedly connected to a rotating motor, the output shaft of the rotating motor is fixedly connected to a rotating screw rod, and the rotating screw rod and the loading push plate are connected by a threaded connection, and the rotating motor is used to drive the loading push plate to move in a horizontal direction. The cutting frame is fixedly connected to the loading motor, and the output shaft of the loading motor is fixedly connected to a first gear, and the cutting frame is rotatably connected to a loading screw rod, and the loading screw rod is fixedly connected to a second gear, the first gear and the second gear are meshed, and the loading screw rod is connected to a loading top plate by a threaded connection, and a loading trough that enables the loading top plate to move upward is provided on the loading push plate.

[0009] The setting of the feeding mechanism can make feeding more convenient on the one hand, as the magnesium ingot only needs to be placed in the feeding trough; on the other hand, it can reduce the probability of replacing the gas in the cutting station when feeding the magnesium ingot, thereby speeding up production efficiency.

[0010] Optionally, the cutting mechanism includes a cutting motor fixedly connected to the cutting frame, a cutting roller rotatably connected to the cutting frame and arranged at the cutting opening, and the cutting roller and the cutting motor are connected by belt drive.

[0011] Optionally, the pushing mechanism includes a pushing cylinder fixedly connected to the cutting frame, and a pushing block is fixedly connected to the output shaft of the pushing cylinder, and the pushing block is used to push the magnesium ingot to move toward the cutting roller.

[0012] Optionally, a blanking port is provided on the cutting frame, and the blanking port is arranged at one end close to the cutting knife roller. A connecting plate is fixedly connected to the cutting frame, and the connecting plates are arranged on both sides of the cutting port. A fixed pushing block is fixedly connected to the side wall of the pushing block, and the fixed pushing block is slidably connected to the connecting plate. A rotating flap is rotatably connected to the side wall of the cutting frame, and the rotating flap is arranged at the blanking port. A sliding plate for fixing the rotating flap is slidably connected to the connecting plate, and a reset spring is fixedly connected to the sliding plate, and the reset spring is used to push the sliding plate to reset, and the fixed pushing block abuts against the sliding plate when the pushing block moves forward, and pushes the sliding plate to move toward the rotating flap.

[0013] By recycling the remaining magnesium ingots, the position in front of the cutting roller is kept clean, which reduces the risk of the cutting roller hitting the cutter. At the same time, by recycling and reusing the magnesium ingots, the waste of magnesium ingot raw materials can be reduced.

[0015] When cutting a magnesium ingot, pressing it can reduce the movement and vibration of the magnesium ingot during the cutting process, thereby improving the cutting accuracy, ensuring the accuracy of the cutting size and shape, and reducing the wear of the tool. During cutting, the unstable clamping of the cutting roller and the magnesium ingot will increase the wear of the tool. Pressing the magnesium ingot can reduce the wear of the tool and extend the service life of the cutting roller.

[0019] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects: 1. When cutting the magnesium ingot, the magnesium ingot located below the cutting station will keep the upper part of the cutting mouth sealed, reducing the consumption of inert gas during the cutting process, thereby reducing production costs. At the same time, the closed state can reduce the oxidation of the magnesium ingot during the cutting process.

[0020] 2. By recycling the remaining magnesium ingots, the front of the cutting roller can be kept clean, reducing the risk of the cutting roller hitting the cutter. At the same time, by recycling and reusing the magnesium ingots, the waste of magnesium ingot raw materials can be reduced.

[0021] 3. The setting of the feeding mechanism can make feeding more convenient on the one hand, as the magnesium ingot only needs to be placed in the feeding trough; on the other hand, it can reduce the probability of replacing the gas in the cutting station when feeding the magnesium ingot, thereby speeding up production efficiency.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the embodiments of the present application. Figure 1-Figure 9 , the technical scheme of the embodiment of the present application is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present application, not all of the embodiments. Based on the described embodiment of the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

[0025] like Figure 1As shown, this embodiment provides a gas-shielded magnesium ingot cutting device, including a cutting frame 1, a pushing mechanism 2, a cutting mechanism 3, a feeding mechanism 4, a dropping mechanism and a pressing mechanism. By placing a magnesium ingot to be cut on the feeding mechanism 4, and pushing the magnesium ingot to move toward the inner position of the cutting frame 1, the magnesium ingot is driven to move upward, so that the pushing mechanism 2 pushes the magnesium ingot to move toward the cutting mechanism 3, and the cutting mechanism 3 cuts the magnesium ingot. After the cutting is completed, the remaining magnesium ingot is dropped through the dropping mechanism, and the subsequent magnesium ingot to be cut is moved upward by feeding. When the magnesium ingot is cut, the magnesium ingot is pushed to contact with the cutting frame 1 by the pressing mechanism to reduce the movement of the magnesium ingot.

[0026] like Figure 2 , Figure 6 and Fig. 9 As shown, a cutting opening 5 is provided on the cutting frame 1, and a pushing top plate 51 is slidably connected to the cutting frame 1.

[0027] The magnesium ingots are moved upward in a vertically stacked manner in the feeding mechanism 4. When the magnesium ingot located at the top moves upward, the side wall of the magnesium ingot pushes the pushing baffle to move, so that the two oppositely arranged pushing baffles move away from each other. After the magnesium ingot moves to the position above the pushing baffle, the magnesium ingot located below is moved upward by the upward movement mechanism, and the pushing baffle moves toward the side wall of the magnesium ingot located below by the pushing spring 52, so that the pushing top plate 51 abuts against the side wall of the magnesium ingot, so that the space where the magnesium ingot being cut above is located is closed, and inert gas is introduced into the space to reduce the oxidation reaction of the magnesium ingot.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the feeding mechanism 4 includes a feeding push plate 41, a rotating motor 42, a rotating screw 43, a feeding motor 44, a feeding screw 49, a first gear 45, a second gear 46 and a feeding top plate 47.

When the rotating screw 43 rotates, it can drive the loading push plate 41 to move toward the inside of the cutting frame 1, the loading motor 44 is fixedly connected to the cutting frame 1, the loading screw 49 is rotatably connected to the cutting frame 1, the first gear 45 is fixedly connected to the output shaft of the loading motor 44, the second gear 46 is fixedly connected to the loading screw 49, and the first gear 45 can engage with the second gear 46, the loading top plate 47 is connected to the loading screw 49 by a thread, and an upward moving groove is provided on the loading push plate 41, and the loading top plate 47 can move up and down in the upward moving groove.

[0029] The feeding motor 44 is started, so that the feeding motor 44 drives the first gear 45 to rotate, and the rotation of the first gear 45 drives the second gear 46 to rotate, and the rotation of the second gear 46 drives the feeding screw rod 49 to rotate, so that the feeding screw rod 49 drives the feeding top plate 47 to move downward, and the feeding top plate 47 moves down to the lower position of the feeding push plate 41, and the rotating motor 42 is started, so that the rotating motor 42 drives the rotating screw rod 43 to rotate, and the rotating screw rod 43 drives the feeding push plate 41 to move toward the outside of the cutting frame 1, and the magnesium ingot is placed in the upper moving groove of the cutting frame 1, and the rotating motor 42 is started, so that the rotating motor 42 drives the rotating screw rod 43 to rotate, so that the feeding push plate 41 moves toward the inside of the cutting plate, and after the upper moving groove moves to the upper position of the upper moving top plate, the feeding motor 44 is started, so that the feeding motor 44 drives the feeding screw rod 49 to rotate, and then the feeding top plate 47 pushes the magnesium ingot located in the upper moving groove to move upward.

[0030] like Figure 1 and Figure 5 As shown, the cutting mechanism 3 includes a cutting motor 31 and a cutting roller 32. The cutting motor 31 is fixedly connected to the side wall of the cutting frame 1. The cutting roller 32 is rotatably connected to the cutting frame 1 and is arranged on a side close to the cutting opening 5. The cutting roller 32 and the cutting motor 31 are connected by a belt transmission. The cutting motor 31 is started, so that the cutting motor 31 drives the cutting roller 32 to rotate, so that the cutting roller 32 cuts the magnesium ingot.

[0031] like Figure 1As shown, the pushing mechanism 2 includes a pushing cylinder 21 and a pushing block 22. The pushing cylinder 21 is fixedly connected to the cutting frame 1, and the output shaft of the pushing cylinder 21 is arranged toward one end of the cutting port 5. The pushing block 22 is fixedly connected to the output shaft of the pushing cylinder 21. The pushing block 22 is used to push the magnesium ingot to move.

[0032] like Figure 2 , Figure 6 and Figure 7 As shown, the blanking mechanism includes a connecting plate 61, a fixed push block 62, a rotating flap 63, a sliding plate 64 and a reset spring 65. A blanking port 6 is provided on the cutting frame 1, and the blanking port 6 is arranged at one end of the cutting frame 1 close to the cutting blade roller 32. The connecting plate 61 is fixedly connected to the cutting frame 1, and the connecting plate 61 is arranged on both sides of the cutting port 5. The fixed push block 62 is fixedly connected to the side wall of the push block 22, and the fixed push block 62 can slide on the side wall of the connecting plate 61. The rotating flap 63 rotates the connecting plate 61. It is connected to the cutting frame 1 and is arranged at the blanking port 6. The sliding plate 64 is slidably connected to the connecting plate 61. When the sliding plate 64 moves toward the rotating flap 63, the rotating flap 63 can be fixed so that the rotating flap 63 no longer rotates. The reset spring 65 is fixedly connected to the sliding plate 64. The reset spring 65 is used to push the sliding plate 64 to reset. When the fixed push block 62 moves, it can abut against the sliding plate 64 to push the sliding plate 64 to move toward one side of the rotating flap 63.

[0033] When cutting the material, the pushing cylinder 21 is started to extend the output shaft of the pushing cylinder 21, and the pushing block 22 moves toward the cutting roller 32, so that the magnesium ingot contacts the cutting roller 32, and the fixed pushing block 62 moves toward the cutting roller 32 driven by the pushing block 22 to cut the magnesium ingot, so that the sliding plate 64 moves toward the rotating flap 63, and the rotating flap 63 is fixed. Before the cutting roller 32 and the pushing block 22 have the risk of colliding, the output shaft of the pushing cylinder 21 retracts, and drives the fixed pushing block 62 to retract, so that the sliding plate 64 is reset under the push of the reset spring 65. At this time, due to the lack of the restriction of the sliding plate 64, the remaining magnesium ingot material body on the rotating flap 63 is flipped over by the action of gravity, so that the magnesium ingot material body moves downward to the collection place for collection.

[0034] like Fig. 9As shown, the clamping mechanism includes a clamping cylinder 7, a clamping plate 71, a clamping push plate 72, a clamping roller 73 and a clamping spring 74. The clamping cylinder 7 is fixedly connected to the cutting frame 1 and is arranged above the blanking port 6. The clamping plate 71 is fixedly connected to the output shaft of the clamping cylinder 7. The push plate is slidably connected to the clamping plate 71. The clamping spring 74 is fixedly connected to the push plate, and one end of the clamping spring 74 away from the push plate is fixedly connected to the clamping plate 71. The clamping roller 73 is rotatably connected to the push plate 72. When cutting the magnesium ingot, the clamping cylinder 7 is started to extend the output shaft of the clamping cylinder 7, drive the clamping plate 71 to move toward the magnesium ingot, and make the clamping roller 73 abut against the upper surface of the magnesium ingot.

[0035] like Figure 2 and Figure 3 As shown, an inflation tube 8 is fixedly connected to the cutting frame 1, the inflation tube 8 is connected to the space above the cutting port 5, and inert gas is introduced into the space, and a sealing plate 9 is fixedly connected to the connecting plate 61, and the sealing plate 9 is used to keep the space above the cutting port 5 and the blanking port 6 sealed.

[0036] When the present application is in use, the loading motor 44 is started, so that the loading motor 44 drives the first gear 45 to rotate, and the first gear 45 rotates to drive the second gear 46 to rotate, and the second gear 46 rotates to drive the loading screw rod 49 to rotate, so that the loading screw rod 49 drives the loading top plate 47 to move downward, and the loading top plate 47 moves down to the lower position of the loading push plate 41, and the rotating motor 42 is started, so that the rotating motor 42 drives the rotating screw rod 43 to rotate, and the rotating screw rod 43 rotates to drive the loading push plate 41 to move toward the outside of the cutting frame 1, and the magnesium ingot is placed in the upper moving groove of the cutting frame 1, and the rotating motor 42 is started, so that the rotating motor 42 drives the rotating screw rod 43 to rotate, so that the loading push plate 41 moves toward the inside of the cutting plate, and after the upper moving groove moves to the upper position of the upper moving top plate, the loading motor 44 is started, so that the loading motor 44 drives the loading screw rod 49 to rotate, and then the loading top plate 47 pushes the magnesium ingot located in the upper moving groove to move upward.

[0037] When the magnesium ingot located at the top moves upward, the side wall of the magnesium ingot pushes the pushing baffle to move, so that the two oppositely arranged pushing baffles move away from each other. After the magnesium ingot moves to the position above the pushing baffle, the magnesium ingot located below moves upward under the push of the upward movement mechanism, and the pushing baffle moves toward the side wall of the magnesium ingot located below under the push of the pushing spring 52, so that the pushing top plate 51 abuts against the side wall of the magnesium ingot, and inert gas is flushed into the space above the cutting port 5 and the blanking port 6 through the inflation pipe 8 to reduce the oxidation reaction of the magnesium ingot.

[0038] Start the cutting motor 31 so that the cutting motor 31 drives the cutting roller 32 to rotate, start the pushing cylinder 21 so that the output shaft of the pushing cylinder 21 extends, and the pushing block 22 moves toward the cutting roller 32 so that the magnesium ingot contacts the cutting roller 32 and cuts the magnesium ingot. Driven by the pushing block 22, the fixed pushing block 62 moves toward the cutting roller 32 so that the sliding plate 64 moves toward the rotating flap 63 so that the rotating flap 63 is fixed. Before the cutting roller 32 and the pushing block 22 have the risk of colliding, the output shaft of the pushing cylinder 21 retracts and drives the fixed pushing block 62 to retract so that the sliding plate 64 is reset under the push of the reset spring 65. At this time, due to the lack of the restriction of the sliding plate 64, the remaining magnesium ingot material on the rotating flap 63 is flipped over by gravity, so that the magnesium ingot material moves downward to the collection location for collection.

[0039] When cutting the magnesium ingot, the abutting cylinder 7 is started to extend the output shaft of the abutting cylinder 7, driving the abutting plate 71 to move toward the magnesium ingot, so that the abutting roller 73 abuts against the upper surface of the magnesium ingot, thereby reducing the movement of the magnesium ingot during cutting.

[0040] In this embodiment, by keeping the magnesium ingot in a closed state during cutting, oxygen is effectively isolated, oxidation of the magnesium ingot is avoided during the cutting process, and the use cost of cutting the magnesium ingot can be reduced. By closing the cutting mouth 5, the consumption of inert gas can be significantly reduced, thereby reducing production costs. In addition, in a closed environment, the inert gas can be recycled to reduce gas loss and improve gas utilization efficiency.

[0041] In this embodiment, the remaining magnesium ingots are recycled and reused to reduce the waste of raw materials, improve resource utilization, keep the front of the cutting roller 32 clean, and reduce the risk of collision. At the same time, if the remaining magnesium ingots accumulate, it will affect the accuracy of the equipment, causing the position of the cutting roller 32 to change. Recycling the remaining magnesium ingots can maintain the accuracy of the equipment.

[0042] In this embodiment, the setting of the feeding mechanism 4 can make feeding more convenient on the one hand, as it only needs to place the magnesium ingot in the upper moving groove; on the other hand, it can reduce the probability of replacing the gas in the cutting station when feeding the magnesium ingot, thereby speeding up production efficiency.

[0043] In this embodiment, when the magnesium ingot is cut, the magnesium ingot is pressed, which can reduce the movement and vibration of the magnesium ingot during the cutting process, thereby improving the cutting accuracy, ensuring the accuracy of the cutting size and shape, and reducing the wear of the tool. During cutting, the instability of the cutting roller 32 and the magnesium ingot will increase the wear of the tool. Pressing the magnesium ingot can reduce the wear of the tool and extend the service life of the cutting roller 32.

[0044] The implementation principle of a gas-protected magnesium ingot cutting device in the embodiment of the present application is: The feeding motor 44 is started, so that the feeding motor 44 drives the first gear 45 to rotate, and the rotation of the first gear 45 drives the second gear 46 to rotate, and the rotation of the second gear 46 drives the feeding screw rod 49 to rotate, so that the feeding screw rod 49 drives the feeding top plate 47 to move downward, and the feeding top plate 47 moves down to the lower position of the feeding push plate 41, and the rotating motor 42 is started, so that the rotating motor 42 drives the rotating screw rod 43 to rotate, and the rotating screw rod 43 drives the feeding push plate 41 to move toward the outside of the cutting frame 1, and the magnesium ingot is placed in the upper moving groove of the cutting frame 1, and the rotating motor 42 is started, so that the rotating motor 42 drives the rotating screw rod 43 to rotate, so that the feeding push plate 41 moves toward the inside of the cutting plate, and after the upper moving groove moves to the upper position of the upper moving top plate, the feeding motor 44 is started, so that the feeding motor 44 drives the feeding screw rod 49 to rotate, and then the feeding top plate 47 pushes the magnesium ingot located in the upper moving groove to move upward.

[0045] When the magnesium ingot located at the top moves upward, the side wall of the magnesium ingot pushes the pushing baffle to move, so that the two oppositely arranged pushing baffles move away from each other. After the magnesium ingot moves to the position above the pushing baffle, the magnesium ingot located below moves upward under the push of the upward movement mechanism, and the pushing baffle moves toward the side wall of the magnesium ingot located below under the push of the pushing spring 52, so that the pushing top plate 51 abuts against the side wall of the magnesium ingot, and inert gas is flushed into the space above the cutting port 5 and the blanking port 6 through the inflation pipe 8 to reduce the oxidation reaction of the magnesium ingot.

[0046] Start the cutting motor 31 so that the cutting motor 31 drives the cutting roller 32 to rotate, start the pushing cylinder 21 so that the output shaft of the pushing cylinder 21 extends, and the pushing block 22 moves toward the cutting roller 32 so that the magnesium ingot contacts the cutting roller 32 and cuts the magnesium ingot. Driven by the pushing block 22, the fixed pushing block 62 moves toward the cutting roller 32 so that the sliding plate 64 moves toward the rotating flap 63 so that the rotating flap 63 is fixed. Before the cutting roller 32 and the pushing block 22 have the risk of colliding, the output shaft of the pushing cylinder 21 retracts and drives the fixed pushing block 62 to retract so that the sliding plate 64 is reset under the push of the reset spring 65. At this time, due to the lack of the restriction of the sliding plate 64, the remaining magnesium ingot material on the rotating flap 63 is flipped over by gravity, so that the magnesium ingot material moves downward to the collection location for collection.

[0047] When cutting the magnesium ingot, the abutting cylinder 7 is started to extend the output shaft of the abutting cylinder 7, driving the abutting plate 71 to move toward the magnesium ingot, so that the abutting roller 73 abuts against the upper surface of the magnesium ingot, thereby reducing the movement of the magnesium ingot during cutting.
