Description

Technical Field

[0001] The invention relates to the technical field of cutting machines, in particular to a magnesium ingot cutting machine. Background Art

[0002] Magnesium powder is a kind of fine magnesium metal particles. Due to its excellent physical and chemical properties, magnesium powder is widely used in various fields. It is an important raw material for lightweight materials, chemical reactions and advanced manufacturing processes. Under normal circumstances, the production of magnesium powder is to mechanically crush magnesium ingots through a cutting machine to form fine powder.

[0003] The existing magnesium powder cutting machine usually clamps and fixes the magnesium ingot by driving the clamping mechanism through a power mechanism such as a hydraulic or cylinder, and then pushes the magnesium ingot toward a rotating cutting tool group driven by a motor to achieve the cutting effect on the magnesium ingot. When the magnesium ingot cutting machine with this structure is in use, after the cutting of the magnesium ingot is completed, it is usually necessary to readjust the clamping mechanism to clamp and fix the new magnesium ingot before cutting can be performed. The magnesium ingot cannot be cut continuously, thereby reducing the efficiency of magnesium ingot cutting. At the same time, since the magnesium ingot needs to be manually clamped, the labor cost of the magnesium ingot cutting operation is increased, and the production cost of magnesium powder is increased. Furthermore, the magnesium powder obtained by simply cutting and powdering the magnesium ingot with a rotating cutting tool group has poor uniformity and the size of the magnesium powder is large, which affects the use of the magnesium powder.

[0013] Compared with the prior art, the invention has the following beneficial effects: the height adjustment mechanism and the material pressing mechanism clamp and fix the magnesium ingot, and the material shifting mechanism shifts the magnesium ingot to the cutting mechanism for cutting. The magnesium ingot does not need to be manually clamped and fixed, and the magnesium ingot can be continuously cut, thereby improving the efficiency of magnesium ingot cutting, reducing labor costs, and reducing the production cost of magnesium powder. The magnesium bars obtained after cutting are sequentially passed through the bar breaking mechanism and the grinding mechanism, thereby obtaining magnesium powder with small size and high uniformity. Specifically: 1. The pressing mechanism drives the positioning plate to rotate in a circle. The positioning plate drives the positioning gear to rotate along the meshing material-pickup gear ring through the positioning column. While the positioning gear rotates, the positioning connecting rod drives the material-pickup slider to slide along the positioning slider. The positioning slider slides along the dovetail slide, so that the material-pickup protrusion moves periodically along the rounded triangle-like motion trajectory, thereby continuously pushing the magnesium ingot to the cutting mechanism for cutting. There is no need to manually drive the magnesium ingot to move, which improves the continuity of magnesium ingot cutting, thereby improving the efficiency of magnesium ingot cutting and further reducing the manufacturing cost of magnesium powder; 2. The moving worm drives the moving sleeve to rotate through the moving worm gear, and then drives the moving plate to move through the moving screw matched with its thread. When the moving plate moves, the symmetrically arranged connecting arm, the height adjustment arm and the rotating arm drive the height adjustment slide plate to move up and down. The height adjustment slide plate drives the height adjustment roller to move synchronously through the height adjustment rod and the height adjustment spring, thereby providing a stable and uniform downward pressure for the magnesium ingot, avoiding the edge warping of the magnesium ingot during the cutting process, and improving the cutting stability of the magnesium ingot. At the same time, the self-locking feature of the meshing of the moving worm and the moving worm gear improves the height stability of the moving roller. 3. The pressing mechanism moves the magnesium ingot through the clamping rollers that rotate symmetrically and in opposite directions, while preventing the magnesium ingot from shifting during the movement, ensuring the stability of magnesium ingot cutting, improving the uniformity of magnesium ingot cutting products, and improving the uniformity and quality of magnesium powder products; 4. The pressing mechanism drives the pressing slider to maintain the movement trend away from the pressing roller through the pressing tension spring, and the pressing slider drives the pressing bracket to maintain the trend of clockwise rotation through the pressing support arm. Furthermore, the pressing bracket drives the pressing roller to maintain the trend of moving downward, thereby assisting the pressing of the magnesium ingot during the movement process, improving the stability of the magnesium ingot during the grinding process, and improving the production quality of magnesium powder; 5. The cutting mechanism makes the cutting roller and the cleaning roller rotate synchronously through the mutually meshing cutting gear and the cleaning gear. The rotating cutting roller performs efficient cutting operation on the magnesium ingot. The cleaning roller cleans the cutting roller during the rotation process to avoid the cutting roller from being contaminated and extend the service life of the cutting roller. 6. The bar-breaking mechanism cuts the magnesium bars obtained by cutting the magnesium ingots through the rotating bar-breaking plate, thereby obtaining magnesium bars of smaller size. After that, the magnesium bars enter the grinding mechanism, and are ground to obtain magnesium powder of higher uniformity and smaller size. Through the setting of the air inlet and air outlet pipes, the bar-breaking mechanism and the grinding mechanism are operated in an inert gas protective atmosphere, which reduces the oxidation of magnesium powder, avoids the spontaneous combustion of magnesium powder, improves the production quality of magnesium powder, and improves the safety of production; 7. The unloading mechanism is intermittently opened through the driving of the cutting roller, which facilitates the transfer of the magnesium bar to the bar breaking mechanism while reducing the loss of inert gas, improving the utilization rate of inert gas, reducing the production cost of magnesium powder, and preventing oxygen from entering the bar breaking mechanism and the grinding mechanism, thereby improving production safety.

[0027] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0028] Combined with Figure 1 , Attachment Figure 2 With attached Figure 3As shown, a magnesium ingot cutting machine comprises a frame 1, on which a cutting mechanism 5 for cutting the magnesium ingot is provided, on which a material shifting mechanism 2 for shifting the magnesium ingot from the frame 1 to the cutting mechanism 5 is provided, and on which a height adjustment mechanism 3 for pressing down the magnesium ingot and a material pressing mechanism 4 for clamping and limiting the magnesium ingot are provided in sequence in the forward direction of the movement of the magnesium ingot, the material pressing mechanism 4 drives the material shifting mechanism 2 to move, and on the frame 1, below the cutting mechanism 5, a bar breaking mechanism 6 for breaking the magnesium bars after cutting and a grinding mechanism 7 for grinding the broken magnesium bars are provided in sequence.

[0029] The working principle of the present invention is as follows: a plurality of groups of magnesium ingots are placed on the frame 1, and the magnesium ingots are placed in a stacked manner above the material-displacing mechanism 2. During operation, the material-displacing mechanism 2 moves the lowest magnesium ingot toward the direction close to the cutting mechanism 5, and the height-adjusting mechanism 3 and the pressing mechanism 4 clamp and limit the magnesium ingot through the joint action of the longitudinal and lateral directions, thereby preventing the magnesium ingot from shifting during movement. When the magnesium ingot moves to the cutting mechanism 5 in a moving state, the cutting mechanism 5 cuts the magnesium ingot to obtain a larger magnesium bar. Afterwards, under the action of gravity, the larger magnesium bar enters the bar-breaking mechanism 6. The bar-breaking mechanism 6 and the grinding mechanism 7 both operate under the protection of inert gas. The larger magnesium bar enters the bar-breaking mechanism 6 and is cut into smaller magnesium bars. The smaller magnesium bars enter the grinding mechanism 7 under the action of gravity and the wind force of the flowing inert gas. The grinding mechanism 7 grinds the smaller magnesium bars into magnesium powder with higher uniformity and smaller size, thereby realizing the cutting operation of the magnesium ingot.

A placement bracket 11 cooperating with the material-discharging protrusion 2233 is provided on the frame 1. A discharge port 111 cooperating with the magnesium ingot is provided on one side of the placement bracket 11. A positioning plate 23 is rotatably provided on the frame 1. A positioning column 232 is eccentrically provided on the positioning plate 23.

A positioning connecting rod 241 rotatably connected with the material-discharging slider 223 is eccentrically provided on the positioning gear 24. A material-discharging roller 12 is rotatably provided on the frame 1. A plurality of groups of material-discharging rollers 12 are equidistantly arranged along the linear direction.

[0031] Working principle of the material-dispensing mechanism 2: during the circular rotation of the positioning plate 23, the positioning plate 23 drives the positioning column 232 to rotate synchronously. During this process, the positioning column 232 drives the positioning gear 24 to rotate along the material-dispensing gear ring 21 meshing therewith. During the rotation, the positioning gear 24 drives the positioning connecting rod 241 eccentrically connected thereto to rotate. Since the positioning connecting rod 241 is rotationally connected to the material-dispensing slider 223, and under the cooperation of the sliding limit of the positioning slider 222 on the material-dispensing slider 223 and the sliding limit of the dovetail slide 221 on the dovetail slider 2221, the material-dispensing cavity 2231 drives the material-dispensing spring 2231 to rotate. The spring 2232 and the material-pickup protrusion 2233 move periodically along a rounded triangle-like motion trajectory. When the wedge-shaped material-pickup protrusion 2233 moves toward the cutting mechanism 5, the material-pickup protrusion 2233 pushes the magnesium ingot toward the cutting mechanism 5 for cutting. The setting of the material-shifting roller 12 reduces the friction during the movement of the magnesium ingot. Afterwards, the material-pickup protrusion 2233 moves obliquely downward away from the cutting mechanism 5, separates from the magnesium ingot, and then moves obliquely upward away from the cutting mechanism 5 to enter a position ready to push the magnesium ingot, preparing for the next material-pickup. This cycle is repeated to achieve the operation of continuously pushing the magnesium ingot toward the cutting mechanism 5.

[0041] The working principle of the bar breaking mechanism 6 and the grinding mechanism 7 is as follows: the inert gas enters the bar breaking mechanism 6 through the air inlet pipe 63 and then enters the grinding mechanism 7 and flows out through the air outlet pipe 72, thereby realizing the protection of the inert gas during the operation of the bar breaking mechanism 6 and the grinding mechanism 7; the bar breaking shaft 61 rotates, and the bar breaking shaft 61 drives the bar breaking plate 62 to rotate, thereby cutting the long magnesium bar obtained by cutting; the cut magnesium bar enters the grinding sleeve 74 under the action of gravity and the blowing of the inert gas; the grinding column 71 drives the grinding key 714 to rotate synchronously; as the inner diameters of the aggregate area 711, the coarse grinding area 712 and the fine grinding area 713 gradually increase, the magnesium bar after breaking passes through the aggregate area 711, the coarse grinding area 712 and the fine grinding area 713 in turn under the rotation of the rotating grinding column 71, and completes the grinding under the action of shear force and extrusion force; the ground coal powder flows out through the discharge pipe 73, thereby realizing the cutting operation of the magnesium ingot.

[0042] Combined with Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Fig.10 With attached Fig.11As shown, the lower end of the rotating hopper 13 is provided with a feeding mechanism 8 which is intermittently opened and closed by a cutting roller 51 to realize feeding of magnesium strips. The feeding mechanism 8 includes a feeding bracket 83 and an L-shaped connecting plate 814 arranged at the lower end of the rotating hopper 13. A feeding roller 82 is rotatably arranged on the feeding bracket 83. A feeding pulley 822 is arranged on one side of the feeding roller 82. A cutting pulley 53 is arranged on the power bevel gear 531. A transmission belt 532 is arranged between the cutting pulley 53 and the feeding pulley 822. A material unloading chute 821 is provided on the material unloading roller 82, and the material unloading chute 821 is a straight-line structure. A material unloading slide rod 811 is slidably provided on the L-shaped connecting plate 814, and a material unloading baffle plate 81 is provided at one end of the material unloading slide rod 811, which extends into the rotating hopper 13 and is slidably connected to the rotating hopper 13. A material unloading spring 812 connected to the L-shaped connecting plate 814 is sleeved on the material unloading slide rod 811, and a material unloading slide column 813 slidably matched with the material unloading chute 821 is provided at the other end of the material unloading slide rod 811.

[0043] The working principle of the unloading mechanism 8 is as follows: when the cutting pulley 53 rotates, the cutting pulley 53 drives the unloading pulley 822 to rotate through the transmission belt 532, and the unloading pulley 822 drives the unloading roller 82 connected thereto to rotate. When the unloading roller 82 rotates, the unloading chute 821 rotates synchronously. In this process, due to the sliding limiting effect of the L-shaped connecting plate 814 on the unloading slide bar 811, and with the cooperation of the unloading spring 812, the rotating unloading chute 821 can drive the unloading slide bar 811 and the unloading baffle 81 to slide back and forth through the unloading slide column 813 slidably connected thereto, thereby realizing the cyclic opening and closing of the rotating hopper 13, making it convenient for the magnesium strips cut by the cutting mechanism 5 to fall to the strip breaking mechanism 6, and at the same time, it can reduce the loss of inert gas, improve the utilization rate of inert gas, and improve the protection ability of coal powder.

[0044] During the specific implementation of the present invention, multiple groups of magnesium ingots are stacked and placed inside the placement bracket 11, and the air inlet pipe 63 and the air outlet pipe 72 are connected to the external inert gas providing mechanism and the external gas recovery mechanism respectively. Inert gas is filled into the broken bar sleeve 64 and the grinding sleeve 74 and maintained, and the movable worm 334 is driven to rotate according to the thickness of the magnesium ingot so that the height adjustment roller 323 can provide a suitable downward pressure for the magnesium ingot. After that, the driving column 43 is driven to rotate, and the driving power bevel gear 531 is driven to rotate. The driving column 43 drives the material-pickup protrusion 2233 to perform periodic motion along the rounded triangle-like motion trajectory, so that the magnesium ingot is pushed toward the cutting roller 51. The driving column 43 drives multiple groups of clamping rollers 44 to rotate, and the multiple groups of clamping rollers 44 rotating in opposite directions drive the magnesium ingot. Move toward the cutting roller 51, the height adjustment mechanism 3 cooperates with the pressing mechanism 45 to prevent the magnesium ingot from warping. When the magnesium ingot contacts the rotating cutting roller 51, the magnesium ingot is cut into strips of magnesium. The magnesium strips fall into the rotating hopper 13 under the action of gravity. When the intermittently opened discharge baffle 81 is opened, the magnesium strips enter the strip breaking sleeve 64, and the rotating strip breaking plate 62 cuts the magnesium strips into shorter strips. Then, under the action of gravity and the wind force of the flowing inert gas, the magnesium strips enter the grinding sleeve 74 and contact the rotating grinding rotor 71. The broken magnesium strips pass through the gathering area 711, the coarse grinding area 712 and the fine grinding area 713 in turn, and the grinding is completed under the action of shear force and extrusion force. The ground coal powder flows out through the discharge pipe 73, thereby realizing the cutting operation of the magnesium ingot.

The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it and do not deviate from the purpose of the invention, they can creatively design a structure and embodiment similar to the technical solution, which should fall within the protection scope of the present invention.
