Description

Technical Field

[0001] This application relates to the technical field of magnesium ingot cutting, and specifically relates to a gas-protected magnesium ingot cutting device. Background Art

[0002] When preparing magnesium powder, it is necessary to first cut the magnesium ingot made of metallic magnesium to break the cut magnesium ingot, so that metal magnesium chips are produced when the magnesium ingot is cut, and the magnesium ingot chips are fed into equipment such as a ball mill or a vibration mill, and the magnesium ingot chips and the grinding medium are ground together to break the magnesium ingot casting into powder.

[0003] Referring to the Chinese patent application document with the publication number CN116689768A and the theme name of a gas-protected metal ingot cutting device, this device is provided with a gas protection cover. By filling the gas protection cover with a protective gas, it is possible to prevent the metal ingot from contacting the air and generating an oxidation reaction, avoiding affecting the purity. At the same time, it is possible to prevent the chips after cutting from contacting the air due to the too high temperature of the cutting tool during cutting, resulting in an explosion and combustion phenomenon.

[0004] For the above technical solution, during the process of cutting the magnesium ingot, first, the magnesium ingot needs to be accurately conveyed to the cutting station. Due to the limitation of the operation space size, there is a certain operation difficulty during the feeding process of the magnesium ingot. After the feeding is completed, in order to ensure the safety of the cutting process and the quality of the magnesium ingot, it is necessary to replace the air inside the gas protection cover. During the air replacement process, the operator needs to closely observe the oxygen concentration inside the gas protection cover to ensure that it reaches the safety standard. After the feeding is completed, in order to further ensure the safety of the cutting process, it is necessary to replace the internal gas again and replace the gas with an inert gas, and then perform cutting. During this process, a large amount of gas in the cutting station needs to be replaced in order to cut the magnesium ingot, which affects the production efficiency. Summary of the Invention

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

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 towards the magnesium ingot.

[0007] When cutting magnesium ingots, the magnesium ingots located below the cutting station will keep the upper position of the cutting opening sealed, reducing the consumption of inert gas during the cutting process, thereby reducing production costs. At the same time, it can reduce the oxidation of magnesium ingots during the cutting process through a sealed state.

Detailed implementation manners

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below in conjunction with the Figures 1-9 of the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, rather than all of them. Based on the described embodiments of this application, all other embodiments obtained by those of ordinary skill in the art belong to the scope protected by this application.

[0034] As Figure 1 shown, this embodiment provides a gas-protected magnesium ingot cutting device, including a cutting frame 1, a pushing mechanism 2, a cutting mechanism 3, a feeding mechanism 4, a blanking mechanism, and a pressing mechanism. By placing the magnesium ingot to be cut on the feeding mechanism 4 and pushing the magnesium ingot to move inside the cutting frame 1, driving the magnesium ingot to move upward, the pushing mechanism 2 pushes the magnesium ingot towards the cutting mechanism 3, enabling the cutting mechanism 3 to cut the magnesium ingot. After cutting, the remaining magnesium ingot is dropped through the blanking mechanism, and the subsequent magnesium ingot to be cut is moved upward through the feeding mechanism. When cutting the magnesium ingot, the pressing mechanism is used to push the magnesium ingot into contact with the cutting frame 1 to reduce the movement of the magnesium ingot.

[0035] As Figure 2 、 Figure 6 and Figure 9 shown, a cutting opening 5 is formed on the cutting frame 1. A pushing top plate 51 is slidably connected to the cutting frame 1. The pushing top plate 51 is arranged at the side wall of the cutting opening 5 on the cutting frame 1. The pushing top plate 51 is set to fit the side wall of the magnesium ingot, and two pushing top plates 51 are arranged in a single cutting opening 5 for fitting the side wall of the magnesium ingot. A pushing spring 52 is fixedly connected to the pushing top plate 51. The end of the pushing spring 52 away from the cutting opening 5 is fixedly connected to the cutting frame 1. The pushing spring 52 is used to push the pushing top plate 51 towards the side wall of the magnesium ingot.

[0036] The magnesium ingots are moved upward in a vertically stacked manner in the feeding mechanism 4. When the uppermost magnesium ingot moves upward, the side wall of the magnesium ingot pushes the pushing baffle to move, causing the two relatively arranged pushing baffles to move away from each other. After this magnesium ingot moves above the pushing baffle, the magnesium ingot below moves upward under the push of the feeding mechanism. The pushing baffle moves towards the side wall of the magnesium ingot below under the push of the pushing spring 52, enabling the pushing top plate 51 to abut against the side wall of the magnesium ingot, making the space where the magnesium ingot to be cut above airtight, and introducing an inert gas into this space to reduce the oxidation reaction of the magnesium ingot.

[0037] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown in the figure, the feeding mechanism 4 includes a feeding push plate 41, a rotating motor 42, a rotating lead screw 43, a feeding motor 44, a feeding lead screw 49, a first gear 45, a second gear 46, and a feeding top plate 47. The feeding push plate 41 is slidably connected to the cutting frame 1. The rotating motor 42 is fixedly connected to the side wall of the cutting frame 1. The output shaft of the rotating motor 42 extends into the cutting frame 1. The rotating lead screw 43 is rotatably connected to the cutting frame 1 and is fixedly connected to the output shaft of the rotating motor 42. The rotating lead screw 43 is connected to the feeding push plate 41 through the thread on the rotating lead screw 43. When the rotating lead screw 43 rotates, it can drive the feeding push plate 41 to move towards the inside of the cutting frame 1. The feeding motor 44 is fixedly connected in the cutting frame 1. The feeding lead screw 49 is rotatably connected in the cutting frame 1. The first gear 45 is fixedly connected to the output shaft of the feeding motor 44. The second gear 46 is fixedly connected to the feeding lead screw 49, and the first gear 45 can mesh with the second gear 46. The feeding top plate 47 is connected to the feeding lead screw 49 through a thread. An upward movement groove is provided on the feeding push plate 41, and the feeding top plate 47 can move up and down in the upward movement groove.

[0038] Start the feeding motor 44 to drive the first gear 45 to rotate. The rotation of the first gear 45 drives the second gear 46 to rotate. The rotation of the second gear 46 drives the feeding lead screw 49 to rotate, so that the feeding lead screw 49 drives the feeding top plate 47 to move downward, so that the feeding top plate 47 moves downward to a position below the feeding push plate 41. Start the rotating motor 42 to drive the rotating lead screw 43 to rotate. The rotation of the rotating lead screw 43 drives the feeding push plate 41 to move towards the outside of the cutting frame 1. Place the magnesium ingot in the upward movement groove of the cutting frame 1, and start the rotating motor 42 to drive the rotating lead screw 43 to rotate, so that the feeding push plate 41 moves towards the inside of the cutting plate. After the upward movement groove moves to a position above the upward movement top plate, start the feeding motor 44 to drive the feeding lead screw 49 to rotate, and then the feeding top plate 47 pushes the magnesium ingot located in the upward movement groove to move upward.

[0039] As Figure 1 and Figure 5 As shown in the figure, the cutting mechanism 3 includes a cutting motor 31 and a cutting knife roller 32. The cutting motor 31 is fixedly connected to the side wall of the cutting frame 1. The cutting knife roller 32 is rotatably connected to the cutting frame 1 and is arranged on one side close to the cutting port 5. The cutting knife roller 32 and the cutting motor 31 are connected by a belt drive. Start the cutting motor 31 to drive the cutting knife roller 32 to rotate, so that the cutting knife roller 32 cuts the magnesium ingot.

[0040] As 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 towards one end of the cutting opening 5. The pushing block 22 is fixedly connected to the output shaft of the pushing cylinder 21, and the pushing block 22 is used to push the magnesium ingot to move.

[0041] As Figure 2 , Figure 6 and Figure 7 shown, the blanking mechanism includes a connecting plate 61, a fixed pushing block 62, a rotating flap 63, a sliding plate 64 and a return spring 65. A blanking opening 6 is formed on the cutting frame 1, and the blanking opening 6 is arranged at one end of the cutting frame 1 close to the cutting knife 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 opening 5. The fixed pushing block 62 is fixedly connected to the side wall of the pushing block 22, and the fixed pushing block 62 can slide on the side wall of the connecting plate 61. The rotating flap 63 is rotatably connected to the cutting frame 1 and is arranged at the blanking opening 6. The sliding plate 64 is slidably connected to the connecting plate 61, and when the sliding plate 64 moves towards the rotating flap 63, it can fix the rotating flap 63 so that the rotating flap 63 no longer rotates. The return spring 65 is fixedly connected to the sliding plate 64, and the return spring 65 is used to push the sliding plate 64 to reset. When the fixed pushing block 62 moves, it can abut against the sliding plate 64 and push the sliding plate 64 to move towards the side of the rotating flap 63.

[0042] When cutting the material, start the pushing cylinder 21 to extend the output shaft of the pushing cylinder 21, and the pushing block 22 moves towards the cutting knife roller 32, so that the magnesium ingot contacts the cutting knife roller 32 to cut the magnesium ingot. The fixed pushing block 62 moves towards the cutting knife roller 32 under the drive of the pushing block 22, so that the sliding plate 64 moves towards the rotating flap 63 to fix the rotating flap 63. Before there is a risk of the cutting knife roller 32 hitting the pushing block 22 during cutting, 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 pushed by the return spring 65 to reset. At this time, due to the lack of restriction of the sliding plate 64, the remaining magnesium ingot body on the rotating flap 63 is driven by gravity to flip, so that the magnesium ingot body moves downward to the collection place for collection.

[0043] As Figure 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 abutting push plate is slidably connected to the clamping plate 71. The clamping spring 74 is fixedly connected to the abutting push plate, and the end of the clamping spring 74 away from the abutting push plate is fixedly connected to the clamping plate 71. A clamping roller 73 is rotatably connected to the clamping push plate 72. When cutting the magnesium ingot, start the clamping cylinder 7 to extend the output shaft of the clamping cylinder 7, drive the clamping plate 71 to move towards the magnesium ingot, and make the clamping roller 73 abut against the upper surface of the magnesium ingot.

[0044] As Figure 2 and Figure 3 shown, an inflation pipe 8 is fixedly connected to the cutting frame 1. The inflation pipe 8 is communicated with the space above the cutting port 5 and inert gas is introduced into this space. A sealing plate 9 is fixedly connected to the connecting plate 61. The sealing plate 9 is used to keep the spaces above the cutting port 5 and the blanking port 6 sealed.

[0045] When this application is in use, start the feeding motor 44 to drive the first gear 45 to rotate. The rotation of the first gear 45 drives the second gear 46 to rotate. The rotation of the second gear 46 drives the feeding lead screw 49 to rotate, so that the feeding lead screw 49 drives the feeding top plate 47 to move downward, and the feeding top plate 47 moves downward to a position below the feeding push plate 41. Start the rotating motor 42 to drive the rotating lead screw 43 to rotate. The rotation of the rotating lead screw 43 drives the feeding push plate 41 to move towards the outside of the cutting frame 1. Place the magnesium ingot in the upper moving groove of the cutting frame 1, and start the rotating motor 42 to drive the rotating lead screw 43 to rotate, so that the feeding push plate 41 moves towards the inside of the cutting plate. After the upper moving groove moves to a position above the upper moving top plate, start the feeding motor 44 to drive the feeding lead screw 49 to rotate, and then the feeding top plate 47 pushes the magnesium ingot located in the upper moving groove to move upward.

[0046] When the uppermost magnesium ingot 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 upward to a position above the pushing baffle, the magnesium ingot located below moves upward under the push of the feeding mechanism. The pushing baffle moves towards 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 introduced into the spaces above the cutting port 5 and the blanking port 6 through the inflation pipe 8 to reduce the oxidation reaction of the magnesium ingot.

[0047] Start the cutting motor 31 to drive the cutting knife roller 32 to rotate. Start the pushing air cylinder 21 to extend the output shaft of the pushing air cylinder 21, and the pushing block 22 moves towards the cutting knife roller 32, making the magnesium ingot contact the cutting knife roller 32 to cut the magnesium ingot. The fixed pushing block 62 moves towards the cutting knife roller 32 driven by the pushing block 22, making the sliding plate 64 move towards the rotating flap 63 to fix the rotating flap 63. Before there is a risk of the cutting knife roller 32 hitting the pushing block 22 during cutting, the output shaft of the pushing air 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 return spring 65. At this time, due to the lack of restriction of the sliding plate 64, the remaining magnesium ingot material on the rotating flap 63 flips under the action of gravity, making the magnesium ingot material move downward to the collection place for collection.

[0048] When cutting the magnesium ingot, start the clamping air cylinder 7 to extend the output shaft of the clamping air cylinder 7, driving the clamping plate 71 to move towards the magnesium ingot, and making the clamping roller 73 abut against the upper surface of the magnesium ingot to reduce the movement of the magnesium ingot during cutting.

[0049] In this embodiment, by keeping the magnesium ingot in a sealed state during cutting, oxygen can be effectively isolated to avoid oxidation of the magnesium ingot during cutting, and the use cost during cutting the magnesium ingot can be reduced. By sealing the cutting port 5, the consumption of inert gas can be significantly reduced, thereby reducing the production cost. And in the sealed environment, the inert gas can be recycled to reduce gas loss and improve the gas utilization efficiency.

[0050] In this embodiment, by recycling and reusing the remaining magnesium ingot, the waste of raw materials can be reduced, the resource utilization rate can be improved, and the cleanliness of the position in front of the cutting knife roller 32 can be maintained to reduce the risk of hitting the knife. At the same time, if the remaining magnesium ingots accumulate, it will affect the accuracy of the equipment, causing the position of the cutting knife roller 32 to change. Recycling the remaining magnesium ingot can maintain the accuracy of the equipment.

[0051] In this embodiment, the setting of the feeding mechanism 4 can, on the one hand, make feeding more convenient, only need to place the magnesium ingot in the upward moving groove, and on the other hand, can reduce the probability of replacing the gas in the cutting station when feeding the magnesium ingot, and improve the production efficiency.

[0052] In this embodiment, when cutting the magnesium ingot, pressing the magnesium ingot can reduce the movement and vibration of the magnesium ingot during cutting, thereby improving the cutting accuracy, ensuring the accuracy of the cutting size and shape, and at the same time reducing tool wear. During cutting, due to the unstable contact between the cutting knife roller 32 and the magnesium ingot, tool wear will increase. Pressing the magnesium ingot can reduce tool wear and extend the service life of the cutting knife roller 32.

[0053] In the embodiment of the present application, the implementation principle of a gas-protected magnesium ingot cutting device is as follows:

[0054] Start the feeding motor 44 to drive the first gear 45 to rotate. The rotation of the first gear 45 drives the second gear 46 to rotate. The rotation of the second gear 46 drives the feeding screw rod 49 to rotate, causing the feeding screw rod 49 to drive the feeding top plate 47 to move downward. Move the feeding top plate 47 to a position below the feeding push plate 41. Start the rotating motor 42 to drive the rotating screw rod 43 to rotate. The rotation of the rotating screw rod 43 drives the feeding push plate 41 to move towards the outside of the cutting frame 1. Place the magnesium ingot in the upper moving groove of the cutting frame 1, and start the rotating motor 42 to drive the rotating screw rod 43 to rotate, causing the feeding push plate 41 to move towards the inside of the cutting plate. After the upper moving groove moves to a position above the upper moving top plate, start the feeding motor 44 to drive 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.

[0055] When the uppermost magnesium ingot moves upward, the side wall of the magnesium ingot pushes the pushing baffle to move, causing the two oppositely arranged pushing baffles to move away from each other. After the magnesium ingot moves upward to a position above the pushing baffle, the magnesium ingot located below moves upward under the push of the feeding mechanism. The pushing baffle moves towards the side wall of the magnesium ingot located below under the push of the pushing spring 52, causing the pushing top plate 51 to abut against the side wall of the magnesium ingot. Inert gas is introduced into the space above the cutting port 5 and the blanking port 6 through the gas filling pipe 8 to reduce the oxidation reaction of the magnesium ingot.

[0056] Start the cutting motor 31 to drive the cutting knife roller 32 to rotate. Start the pushing cylinder 21 to extend the output shaft of the pushing cylinder 21, and the pushing block 22 moves towards the cutting knife roller 32, causing the magnesium ingot to come into contact with the cutting knife roller 32 for cutting the magnesium ingot. The fixed push block 62 moves towards the cutting knife roller 32 under the drive of the pushing block 22, causing the sliding plate 64 to move towards the rotating flap 63, fixing the rotating flap 63. Before there is a risk of the cutting knife roller 32 colliding with the pushing block 22 during cutting, the output shaft of the pushing cylinder 21 retracts and drives the fixed push block 62 to retract, causing the sliding plate 64 to be reset under the push of the reset spring 65. At this time, due to the lack of restriction of the sliding plate 64, the remaining magnesium ingot material on the rotating flap 63 flips under the action of gravity, causing the magnesium ingot material to move downward to the collection place for collection.

[0057] When cutting the magnesium ingot, the pressing cylinder 7 is started, the output shaft of the pressing cylinder 7 extends, drives the pressing plate 71 to move towards the magnesium ingot, and makes the pressing roller 73 abut against the upper surface of the magnesium ingot, reducing the movement of the magnesium ingot during cutting.

[0058] In addition, it should be noted that in the description of the present application, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0059] The above is the preferred embodiment of the present application. It should be pointed out that for those of ordinary skill in the art, without departing from the principle described in the present application, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present application.
