Description

Technical Field

[0001] The invention relates to the technical field of magnesium ingot processing equipment, and in particular to a magnesium ingot feeding device. Background Art

[0002] Magnesium ingot is a bulk metal material made of magnesium, which is often used to manufacture parts in the aerospace industry, automotive industry, electronic products and other fields.

[0003] The current feeding method of the drum-type magnesium ingot chipping machine is to use the driving end of the hydraulic cylinder to press against one end of the magnesium ingot, and then the driving end of the hydraulic cylinder drives the magnesium ingot to move continuously, so that the magnesium ingot conflicts with the hob and gradually cuts the chips. However, in order to prevent the hydraulic cylinder driving end from extending too long and causing the knife to hit, the feeding is generally stopped when there is still a part of the magnesium ingot left, and the remaining small pieces of magnesium ingot head fall from the drop port, and then the hydraulic cylinder is reset, and then new magnesium ingots are added manually. The head needs to be collected and then returned to the furnace for remelting and processing again.

[0004] Reference is made to a Chinese patent document with authorization announcement number CN213289565U, which discloses a hydraulic magnesium ingot chip breaker, including a frame and a workbench, on which a pushing hydraulic cylinder and a processing seat are arranged, the piston rod of the pushing hydraulic cylinder is fixedly connected to a push plate, a clamping cylinder is arranged on the processing seat, a clamping seat is arranged at the output end of the clamping cylinder, and a clamping wheel is rotatably arranged on the clamping seat. The patent presses the top of the magnesium ingot by the clamping wheel, and then the push plate pushes the magnesium ingot to move, and the magnesium ingot is cut by the milling cutter head. When a part of the magnesium ingot remains, the remaining part is discharged through the drop-out port below.

[0005] With regard to the above-mentioned related technologies, as the magnesium ingot is continuously cut into chips, the length of the magnesium ingot will gradually shorten. When the tail of the magnesium ingot is cut into chips, due to the existence of the drop opening, the bottom of the magnesium ingot is suspended in the air. Therefore, the magnesium ingot will vibrate when being cut into chips, affecting the quality of the magnesium chips. In addition, the magnesium chips will fly when the magnesium ingot is cut into chips, affecting the cutting of the magnesium ingot. Summary of the invention

[0006] In view of this, the present invention provides a magnesium ingot feeding device, aiming to solve the problem of low quality of chips at the tail of the magnesium ingot.

[0007] In order to solve the above technical problems, the present invention provides a magnesium ingot feeding device, comprising a frame, a push plate, a clamping seat and a clamping wheel rotatably arranged at the bottom of the clamping seat, and also comprising: a conveyor belt arranged on the frame for conveying the magnesium ingot, the frame is provided with a working groove, a plurality of support cylinders located on the same horizontal plane are arranged in the working groove, the top of the support cylinder and the top of the conveyor belt are located on the same horizontal plane, the support cylinder can receive the magnesium ingot conveyed by the conveyor belt, the two ends of the support cylinder are hinged with a rotating rod, the push plate is fixedly connected with a first rack, the end of the frame away from the conveyor belt is slidably connected to a limiting frame, the frame is provided with a feeding mechanism that drives the rotating rod to rotate when the first rack moves, and after the rotating rod is rotated, the top of the support cylinder and the bottom of the push plate are located on the same horizontal plane.

[0008] By adopting the above technical scheme, the magnesium ingot is conveyed to the supporting cylinder by the conveyor belt, which is convenient for loading the magnesium ingot and helps to reduce the work intensity of the staff. A plurality of supporting cylinders are used to support the magnesium ingot, and when the push plate moves, the supporting cylinder is driven to move upward so that the push plate can push the magnesium ingot for chip cutting. The magnesium ingot can be supported by the supporting cylinder all the time, thereby improving the stability of the magnesium ingot during chip cutting, which helps to improve the quality of magnesium chips. At the same time, the flying chips generated during chip cutting can fall from the gaps between the supporting cylinders, which helps to improve the cleanliness of the device and facilitate the chip cutting work.

[0009] Optionally, the feeding mechanism includes a first gear meshing with the first rack, the first gear passing through the side wall of the working groove and fixedly connected to a cam, a second rack is slidably arranged on the frame close to the cam, a second gear is meshed with the upper part of the second rack, and the second gear is fixedly connected to the end of the rotating rod away from the supporting cylinder, and the feeding mechanism also includes a locking member for limiting the movement of the second rack.

[0010] By adopting the above technical solution, the push plate can drive the first rack to move during the movement, and the movement of the first rack can drive the rotating rod to rotate. The rotating rod drives the support tube to move to the same horizontal plane as the bottom of the magnesium ingot and the bottom of the push plate. Then the push plate can push the magnesium ingot to move and perform chip cutting. While the conveyor belt facilitates loading, the magnesium ingot can reach the working position when the push plate moves, ensuring that the chip cutting work is carried out normally while improving work efficiency.

[0011] Optionally, the locking member includes a connecting plate fixedly connected to one end of the second rack close to the cam, a limiting hole is formed on the connecting plate, a spring pin cooperating with the limiting hole is slidably provided on the side wall of the working groove, an end of the spring pin away from the second rack is slidably connected to a connecting block, connecting rods are hinged on both sides of the connecting block, a reset torsion spring is sleeved on the connecting rod, a pull rod is hinged on the connecting rod, and the push plate can abut against the pull rod when approaching the first gear.

[0012] By adopting the above technical solution, the cooperation between the spring pin and the limiting hole can limit the movement of the second rack, thereby improving the stability of the support cylinder when supporting the magnesium ingot. When the push plate moves close to the first gear, it can drive the pull rod to rotate. The rotation of the pull rod can drive the connecting block and the spring pin to move to unlock the second rack. Then the support cylinder returns to its initial position under the action of its own gravity to facilitate receiving the next batch of magnesium ingots.

[0013] Optionally, a pull rope is fixedly connected between the rotating rod close to the limiting frame and the limiting frame.

[0014] By adopting the above technical solution, when the support tube is reset, the support tube can drive the limit frame to move through the pull rope, so as to reset the limit frame, thereby limiting the next group of magnesium ingots, which is beneficial to improving work efficiency, and as the limit frame moves, the debris in the gap between the limit frame and the cutter can fall, thereby reducing the impact of the debris on the cutter, which is beneficial to improving the chip quality.

[0015] Optionally, the support tube rotates to drive the limiting frame to slide, and then the limiting frame and the support tube jointly support the magnesium ingot.

[0016] By adopting the above technical solution, the limiting frame and the supporting tube cooperate to support the magnesium ingot when the magnesium ingot is cut into chips, which is beneficial to improving the stability of the magnesium ingot when the magnesium ingot is cut into chips.

[0017] Optionally, a first linear drive is fixedly mounted on the frame, the push plate is fixedly connected to a driving shaft of the first linear drive, a side of the push plate away from the first linear drive is fixedly connected to a top block, and the first linear drive can drive the push plate to move in a horizontal direction.

[0018] By adopting the above technical solution, starting the first linear drive drives the push plate and the top block to move in the horizontal direction. Pushing the magnesium ingot to move by the top block can reduce the probability of the magnesium ingot shifting, which is beneficial to improving the stability of the magnesium ingot during movement.

[0019] Optionally, a second linear actuator is fixedly mounted on one side of the frame close to the limiting frame, the pressing seat is fixedly connected to a driving shaft of the second linear actuator, and the second linear actuator can drive the pressing seat to move in a vertical direction.

[0020] By adopting the above technical solution, the second linear drive can drive the clamping seat and the clamping wheel to move in the vertical direction, and the magnesium ingot can be clamped by the clamping wheel, while the movement of the magnesium ingot is not affected when the magnesium ingot is fed.

[0021] Optionally, an inclined blanking plate is fixedly connected to the frame.

[0022] By adopting the above technical solution, the remaining material heads of the magnesium ingot and the debris generated by the magnesium ingot cutting can fall through the drop plate to facilitate their collection, which reduces the work intensity of the staff and is conducive to improving the work efficiency.

[0023] In summary, compared with the prior art, the present invention includes at least one of the following beneficial technical effects:

[0024] 1. The magnesium ingot is conveyed to the support cylinder by a conveyor belt, which is convenient for loading the magnesium ingot and helps to reduce the work intensity of the staff. Multiple support cylinders are used to support the magnesium ingot. When the push plate moves, the support cylinder is driven to move upward so that the push plate can push the magnesium ingot for chip cutting. The magnesium ingot can be supported by the support cylinder all the time, thereby improving the stability of the magnesium ingot during chip cutting, which is beneficial to improving the quality of magnesium chips. At the same time, the flying chips generated during chip cutting can fall from the gaps between the support cylinders, which is beneficial to improving the cleanliness of the device and facilitating the chip cutting work;

[0025] 2. While the conveyor belt facilitates material loading, the magnesium ingot can reach the working position when the push plate moves, ensuring the normal chip cutting work and improving the work efficiency. The cooperation between the spring pin and the limiting hole can limit the movement of the second rack, thereby improving the stability of the support cylinder when supporting the magnesium ingot. When the push plate is reset, it can drive the pull rod to rotate. The rotation of the pull rod can drive the spring pin to move to unlock the second rack, and then the support cylinder returns to its initial position under the action of its own gravity, so as to receive the next batch of magnesium ingots;

[0026] 3. Start the first linear drive to drive the push plate and the top block to move in the horizontal direction. Pushing the magnesium ingot to move by the top block can reduce the probability of the magnesium ingot shifting, which is beneficial to improving the stability of the magnesium ingot during the movement;

[0034] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be combined with the embodiments of the present invention. Figure 1-Figure 5 , the technical scheme of the embodiment of the present invention is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0035] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4A magnesium ingot feeding device comprises a frame 1 erected on a horizontal plane, a conveyor belt 14 for conveying magnesium ingots is fixedly arranged on the frame 1, two working grooves 15 are provided on the frame 1, a plurality of support cylinders 16 located on the same horizontal plane are arranged in the two working grooves 15, the top of the support cylinder 16 and the top of the conveyor belt 14 are located on the same horizontal plane, the end of the frame 1 away from the conveyor belt 14 is slidably connected to a limiting frame 19, when the conveyor belt 14 conveys the magnesium ingot to the support cylinder 16, the magnesium ingot is limited by the limiting frame 19, a rotating rod 17 close to the limiting frame 19 is fixedly connected to the limiting frame 19, two first linear actuators 4 are fixedly installed on the frame 1, and the driving shaft of each first linear actuator 4 is respectively fixedly connected to a push plate 11, and the push plate 11 is far away from the conveyor belt 14. Two top blocks 41 are fixedly connected to one side away from the first linear drive 4, and the first linear drive 4 can drive the top blocks 41 to push the magnesium ingot to move in the horizontal direction. A second linear drive 5 is fixedly installed on the side of the frame 1 away from the first linear drive 4, and a driving shaft of the second linear drive 5 is fixedly connected to a clamping seat 12, and a plurality of clamping wheels 13 are rotatably connected to the bottom of the clamping seat 12. Both ends of the support cylinder 16 are hinged with a rotating rod 17, and a horizontally arranged first rack 18 is fixedly connected to the side of the push plate 11 close to the first linear drive 4. A feeding mechanism 2 is arranged on the frame 1, which can drive the rotating rod 17 to rotate when the first rack 18 moves, and the rotating rod 17 can drive the support cylinder 16 to move until the top of the support cylinder 16 and the bottom of the push plate 11 are on the same horizontal plane.

[0036] When it is necessary to load the magnesium ingot, the magnesium ingot is first placed on the conveyor belt 14, and then the conveyor belt 14 transports the magnesium ingot to the support cylinder 16. The magnesium ingot stops moving after contacting the limit frame 19, and the first linear drive 4 is started to drive the push plate 11 and the top block 41 to move. As the push plate 11 moves, the loading mechanism 2 drives the rotating rod 17 to rotate and move the support cylinder 16. The support cylinder 16 moves to the same horizontal plane as the top of the support cylinder 16 and the bottom of the push plate 11. Then the second linear drive 5 is started to drive the clamping seat 12 and the clamping wheel 13 to clamp the top of the magnesium ingot. Then the top block 41 pushes the magnesium ingot to move and perform chip cutting. The splashed chips can fall through the gaps between the support cylinders 16, thereby reducing the probability of the chips sticking to the cutter and affecting the chip quality. In addition, the magnesium ingot is supported by multiple support cylinders 16, and the magnesium ingot can be supported when the end of the magnesium ingot is cut, thereby improving the chip quality of the magnesium ingot.

[0037] Reference Figure 1 and Figure 2 A blanking plate 6 fixedly connected to the frame 1 is tiltedly arranged below the support cylinder 16. The remaining material heads of the magnesium ingot and the debris generated by the magnesium ingot chips can fall through the blanking plate 6 to facilitate their collection, which reduces the work intensity of the staff and is conducive to improving work efficiency.

[0038] Reference Figure 1 and Figure 3 The feeding mechanism 2 includes a first gear 21 meshing with the first rack 18, a first support rod passing through the side wall of the working groove 15 is fixedly connected to the middle of the first gear 21, an end of the first support rod away from the first gear 21 is fixedly connected to a cam 22, a horizontally arranged second rack 23 is slidably connected to the frame 1 close to the cam 22, a second gear 24 is meshed on the second rack 23, a second support rod passing through the side wall of the working groove 15 is fixedly connected to the middle of the second gear 24, an end of the second support rod away from the second gear 24 is fixedly connected to an end of the rotating rod 17 away from the supporting cylinder 16, and the feeding mechanism 2 also includes a locking member 25 for limiting the movement of the second rack 23.

[0039] When the rotating rod 17 needs to be rotated, the first rack 18 can drive the first gear 21 to rotate when it moves, and the rotation of the first gear 21 drives the cam 22 to rotate, and the rotation of the cam 22 drives the second rack 23 to slide, and the second rack 23 drives the second gear 24 to rotate when it slides, and the second gear 24 drives the rotating rod 17 to rotate when it rotates, so that the support tube 16 moves and drives the magnesium ingot to move upward, and the magnesium ingot can be moved to the working position while the push plate 11 and the top block 41 drive the magnesium ingot to load. This can reduce the work intensity of the staff and is conducive to improving work efficiency.

[0040] Reference Figure 1 , Figure 3 and Figure 5 The locking member 25 includes a connecting plate 251, a limiting hole 252, a spring pin 253, a connecting block 254, a connecting rod 257, a reset torsion spring 255 and a pull rod 256. The connecting plate 251 is fixedly connected to one end of the second rack 23 close to the cam 22. The limiting hole 252 is opened on the connecting plate 251. The spring pin 253 is slidably arranged on the side wall of the working groove 15. When the second rack 23 moves, the spring pin 253 can be inserted into the limiting hole 252. The connecting block 254 is slidably connected to one end of the spring pin 253 away from the second rack 23. The connecting rod 257 is hinged on both sides of the connecting block 254. The reset torsion spring 255 is sleeved on the connecting rod 257. The pull rod 256 is hinged on the connecting rod 257, and when the push plate 11 moves in the direction close to the first linear actuator 4, it can drive the pull rod 256 to rotate.

[0041] When it is necessary to limit the movement of the second rack 23, the second rack 23 can drive the connecting plate 251 to move when it moves. As the connecting plate 251 moves, the spring pin 253 is inserted into the limiting hole 252, thereby fixing the second rack 23 to facilitate the smooth progress of the magnesium ingot cutting work. After the magnesium ingot cutting is completed, the push plate 11 moves toward the direction close to the first linear drive 4 under the drive of the first linear drive 4. As the push plate 11 moves, the push plate 11 abuts against the pull rod 256 and drives the pull rod 256 to rotate. The rotation of the pull rod 256 drives the connecting block 254 to move so that the spring pin 253 disengages from the limiting hole 252, and then the support cylinder 16 and the rotating rod 17 return to their initial positions under the action of their own gravity, so as to receive the next group of magnesium ingots.

[0042] The implementation principle of a magnesium ingot feeding device according to an embodiment of the present invention is as follows: first, the magnesium ingot is placed on the conveyor belt 14, and then the conveyor belt 14 conveys the magnesium ingot to move onto the support cylinder 16. The magnesium ingot stops moving when it moves to contact with the limit frame 19, and the first linear drive 4 is started to drive the push plate 11 to move. The push plate 11 drives the first rack 18 to move. The movement of the first rack 18 drives the first gear 21 to rotate. The rotation of the first gear 21 drives the cam 22 to rotate. When the cam 22 rotates, it can abut against the connecting plate 251 to make the second rack 23 slide. The sliding of the second rack 23 drives the second gear 24 to rotate. The rotation of the second gear 24 drives the rotation The rod 17 rotates and drives the support cylinder 16 to move, thereby moving the magnesium ingot to the same horizontal plane as the bottom of the magnesium ingot and the bottom of the push plate 11, and starting the second linear drive 5 to drive the clamping seat 12 and the clamping wheel 13 to move and abut against the top of the magnesium ingot, and then the push plate 11 drives the top block 41 to push the magnesium ingot to move and cut the magnesium ingot. After the chip cutting is completed, the push plate 11 moves toward the direction close to the first linear drive 4, and then the push plate 11 drives the pull rod 256 to rotate, and the pull rod 256 drives the spring pin 253 to move, and the support cylinder 16 and the rotating rod 17 return to their initial positions under the action of their own gravity, and continue to cut the next group of magnesium ingots.

[0043] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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 a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] The above is a preferred embodiment of the present invention.
