Description

Technical Field

[0001] The invention relates to the technical field of cleaning of formed magnesium ingots, in particular to a device for cleaning and finishing magnesium ingots after casting. Background Art

[0002] Magnesium ingots are block or ingot-shaped products formed by smelting and casting metallic magnesium. They are often used in the production and processing of aerospace components and structural parts such as automobile wheels. There are usually burrs and flash on the surface of cast magnesium ingots. Generally, they need to be polished by grinding equipment first to avoid scratching subsequent processing equipment or affecting the accuracy of dimensional measurement.

[0003] In the prior art, when magnesium ingots are batch-grinded, after the magnesium ingots are loaded, their two end faces are firstly ground by grinding wheels, and then the two side faces and the upper and lower surfaces of the magnesium ingots are polished in sequence by a plurality of combined grinding wheels, and finally the ingots are pushed out to realize batch grinding of the entire surface of the magnesium ingots. The multi-grinding wheel grinding equipment is usually equipped with a dust cover and a dust suction device on the magnesium ingot grinding operation path to absorb grinding debris and dust.

[0004] However, the traditional method of grinding magnesium ingots with multiple grinding wheel equipment has the following problems: 1. Due to the presence of attached debris on the surface of the magnesium ingot that is not removed in time during the grinding process, and the debris dust that escapes from the inlet and outlet and re-attaches to the surface of the ground magnesium ingot, it may become a "micro-crack source" or stress concentration point in subsequent processing. Especially in high-load scenarios such as aerospace components and automobile wheels, the stress concentration effect caused by these debris will significantly accelerate the fatigue fracture process of the components. At the same time, due to the weak bonding force between the debris and the magnesium ingot matrix, it will cause damage during welding, electroplating, etc. 1. Interface gaps are easily generated during the surface treatment process, resulting in a decrease in coating adhesion or a decrease in weld joint strength, ultimately affecting product performance and processing yield; 2. In the existing technology, although multi-grinding wheel grinding equipment is equipped with a dust cover and a dust suction device on the magnesium ingot grinding operation path, the feed port and the discharge port are always in an open state, resulting in the dust generated by high-speed grinding can still be dynamically dispersed into the workshop environment with the material in and out, making it difficult to completely curb the spread of dust, which not only increases the burden of workshop cleaning, but also affects the health of operators and the safe production of equipment.

[0031] See also Figure 1 and Figure 3 The feeding mechanism 2 includes an isolation bin 21 that passes through from top to bottom. The upper end of the isolation bin 21 is provided with a front-to-back symmetrical inclined surface. The isolation bin 21 is provided with a lifting and conveying part 22 for lifting and conveying the magnesium ingot. The lifting and conveying part 22 is provided with a supporting and limiting part 23 for supporting and limiting the magnesium ingot. The lifting and conveying part 22 and the supporting and limiting part 23 are jointly provided with a feeding isolation part 24 for closing the upper end opening of the isolation bin 21 and isolating dust.

[0032] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 7 The lifting and conveying part 22 includes an L-shaped bracket fixedly arranged on the isolation bin 21 symmetrically on the left and right sides, and a fixed platform 221 located above the isolation bin 21 is fixedly arranged on the upper side of the symmetrical L-shaped bracket. A hydraulic cylinder 222 is fixedly arranged on the upper side of the fixed platform 221, and a circular support bracket 223 that moves up and down along the isolation bin 21 is fixedly arranged at the telescopic end of the hydraulic cylinder 222, wherein the width of the circular support bracket 223 is smaller than the length of the magnesium ingot.

[0033] See also Figure 3 The supporting and limiting portion 23 includes a supporting groove 231 which is opened on the inner side of the circular supporting bracket 223 and passes through from front to back. A plurality of groups of balls 61 are evenly rolled left and right in the supporting groove 231. Each group is composed of a plurality of balls 61 that are symmetrical and evenly distributed up and down. A group of U-shaped partitions 232 are fixedly arranged in the supporting groove 231 and between each group of balls 61. Each group is composed of U-shaped partitions 232 that are symmetrical up and down. Each group of U-shaped partitions 232 jointly divides the supporting groove 231 into a plurality of limiting bins corresponding to each group of balls 61.

[0034] See also Figure 1 、 Figure 2 、 Figure 3 Hehe Figure 7 The feeding isolation part 24 includes a spring rod that is symmetrically fixed on the upper side of the circular support bracket 223 and passes through the fixed platform 221 up and down. A closing plate 241 that moves up and down and is located below the fixed platform 221 is elastically slidably provided on the symmetrical spring rods. A through groove for the telescopic end of the hydraulic cylinder 222 to slide up and down is provided on the closing plate 241. Two groups of mounting grooves that pass through inside and outside are provided on the isolation bin 21 at the front and back. Each group consists of a plurality of mounting grooves evenly distributed on the left and right. The two groups of mounting grooves are staggered left and right. A fan-shaped nozzle 242 for spraying a water curtain into the interior of the isolation bin 21 is installed in the mounting groove.

[0035] When the magnesium ingot is to be loaded, the hydraulic cylinder 222 is first used to drive the circular support bracket 223 to move upward along the isolation bin 21 to the highest point, and the circular support bracket 223 then drives the closing plate 241 to move upward to the highest point synchronously. At this time, the supporting groove 231 inside the circular support bracket 223 is just completely separated from the isolation bin 21. Then, multiple magnesium ingots are loaded into the corresponding limit bins through the loading equipment, and the circular support bracket 223 and the closing plate 241 are driven downward again by the hydraulic cylinder 222. The inclined surface at the upper end of the isolation bin 21 can then correct the front and rear ends of the magnesium ingot in the limit bin until the circular support bracket 223 drives the magnesium ingot to completely enter the isolation bin 21 from the upper end opening of the isolation bin 21. At this time, the closing plate 241 is just against The closing plate 241 is pressed tightly against the upper end of the isolation bin 21 and completely closes its upper end opening. As the circular support bracket 223 continues to move downward, under the action of the spring rod, the closing plate 241 will always stably close the upper end opening of the isolation bin 21. When the closing plate 241 does not close the upper end opening of the isolation bin 21 and the circular support bracket 223 moves upward and resets to the highest point, it is necessary to continuously spray into the isolation bin 21 through a fan-shaped nozzle 242 to form a high-pressure water curtain, so as to fully flush the debris and dust attached to the upward reset circular support bracket 223, and isolate and seal the upper end opening of the isolation bin 21 to prevent debris and dust from escaping from the upper end of the isolation bin 21 during the loading process, and at the same time prevent the residual debris in the circular support bracket 223 from scratching the magnesium ingot.

[0036] See also Figure 1 The grinding mechanism 3 includes a first grinding part 31 located at the lower side of the isolation chamber 21 and a second grinding part 33 arranged in front of the first grinding part 31.

[0037] See also Figure 1 、 Figure 2 and Figure 4 The first grinding part 31 includes a grinding chamber 311 fixedly arranged on the upper side of the bottom plate 1 and fixedly connected to the lower side of the isolation chamber 21. The upper side of the grinding chamber 311 is provided with a docking interface connected to the upper and lower sides of the isolation chamber 21. The front side of the grinding chamber 311 is provided with a feeding port connected inside and outside. The lower surface of the interior of the grinding chamber 311 is provided with a water collecting trough 63. The lower side of the grinding chamber 311 is evenly provided with a plurality of drain outlets 65 connected up and down. There are three grinding groups on the grinding chamber 311, of which the front and rear two of the docking interface are connected. Two groups of grinding groups are symmetrically arranged on the side, and a group of grinding groups symmetrical with the front grinding group is arranged on the lower side of the feeding port; the grinding group includes a motor 312 fixedly arranged on the left side of the grinding chamber 311, and the driving end of the motor 312 is fixedly provided with a connecting shaft rotatably connected to the grinding chamber 311, and a plurality of grinding wheels 313 corresponding to the limit chamber are evenly fixed on the left and right sides of the connecting shaft, and a plurality of negative pressure suction pipes 67 corresponding to the grinding wheels 313 are evenly installed on the grinding chamber 311, and the negative pressure suction pipe 67 is connected to the dust collection mechanism 6.

[0038] When the front and rear end faces of the magnesium ingot are to be polished, the motor 312 is first used to drive the front and rear symmetrical connecting shaft and the grinding wheel 313 to rotate relative to each other, and the hydraulic cylinder 222 is used to drive the circular support bracket 223 and the magnesium ingot to continue to move downward until the circular support bracket 223 and the magnesium ingot move downward from the docking interface into the polishing bin 311, and the front and rear symmetrical grinding wheels 313 then polish the front and rear end faces of the magnesium ingot extending outward from the circular support bracket 223. The limit bin can always stably limit the magnesium ingot to prevent the magnesium ingot from shaking and deflecting during the end face polishing process, thereby affecting the polishing effect. During the transportation of the magnesium ingot, it is necessary to ensure that there is sufficient contact time between the magnesium ingot and the grinding wheel 313 to ensure the polishing effect of the magnesium ingot.

[0039] The water collecting tank 63 and the drain outlet 65 can collect and discharge the water flow containing debris and dust sprayed by the fan-shaped nozzle 242; the dust suction mechanism 6 can use the negative pressure suction pipe 67 to remove most of the debris generated by the grinding wheel 313.

The forward conveying part 32 includes a plurality of multi-stage cylinders 321 evenly fixed on the left and right sides of the rear side of the grinding bin 311 and corresponding to the limit bin. A plurality of receiving grooves 1 corresponding to the multi-stage cylinders 321 and located below the rear grinding group are evenly opened on the left and right sides of the rear side of the grinding bin 311. A push plate 322 is fixed at the telescopic end of the multi-stage cylinder 321, which moves forward and backward and is plugged into the corresponding receiving groove.

[0041] See also Figure 1 、 Figure 2 and Figure 5 The second grinding part 33 includes a grinding chamber 2 331 fixedly arranged on the front side of the grinding chamber 1 311, and a plurality of motors 2 332 are evenly fixedly arranged on the left and right sides of the upper side of the grinding chamber 2 331, and a grinding wheel 2 333 located inside the grinding chamber 2 331 is fixedly provided on the driving end of the motor 2 332, and a feeding trough corresponding to the limiting chamber and connected to the feeding port front and back is provided on the grinding chamber 2 331 and between adjacent grinding wheels 2 333, and a plurality of negative pressure suction pipes 2 68 corresponding to the feeding trough are evenly installed on the lower side of the grinding chamber 2 331, and a plurality of evenly distributed balls 2 62 are symmetrically rolled on the grinding chamber 2 331 and located in the feeding trough, and a material guide plate 334 is symmetrically fixed on the rear side of the grinding chamber 2 331 and located on the left and right sides of the corresponding feeding trough, and the material guide plate 334 is located inside the grinding chamber 1 311.

[0042] When the upper, lower and side surfaces of the magnesium ingot are to be polished, the magnesium ingot is first driven downward to the bottom of the polishing bin 1 311 by the circular support bracket 223, and then the upper and lower symmetrical connecting shafts and the polishing wheel 1 313 are driven to rotate relative to each other by the motor 1 312, and the adjacent polishing wheels 2 333 are driven to rotate relative to each other by the motor 2 332. At this time, each magnesium ingot is aligned with the corresponding push plate 1 322, and then the push plate 1 322 is driven forward by the multi-stage cylinder 1 321, and the push plate 1 322 pushes the corresponding magnesium ingot forward. The magnesium ingot is then continuously pushed forward by the limit bin, and the upper and lower symmetrical polishing wheels 1 313 are driven to rotate relative to each other. The upper and lower surfaces of the magnesium ingot are polished, and at the same time, the magnesium ingot stably enters the corresponding feed trough in the polishing chamber 2 331 under the guidance limit of the guide plate 334, and the corresponding adjacent polishing wheel 2 333 then polishes the side surface of the magnesium ingot until the magnesium ingot is pushed forward out of the polishing chamber 2 331 by the push plate 1 322. The ball 1 61 in the limit chamber and the ball 2 62 in the feed trough can reduce the friction resistance of the magnesium ingot when it is transported forward, so as to avoid the friction resistance causing the magnesium ingot to deflect during the polishing process and affect the polishing effect. The dust suction mechanism 6 can use the negative pressure suction pipe 2 68 to remove most of the debris generated by the polishing of the polishing wheel 2 333 by negative pressure.

[0043] The above-mentioned operation method can not only realize the simultaneous full-surface grinding of multiple magnesium ingots at one time through a single device, but also achieve the grinding needs of the same number of magnesium ingots with fewer grinding wheels by optimizing the grinding wheel layout and the magnesium ingot conveying path compared to the traditional parallel operation of multiple devices. For example, the front end face and upper surface of the magnesium ingot can be ground only by the front grinding group, thereby reducing hardware investment and energy consumption while ensuring the overall processing efficiency of the magnesium ingots and reducing the overall processing cost.

[0048] When the magnesium ingot is continuously pushed forward by the pushing plate 1 322 , a high-pressure water curtain is first sprayed into the corresponding circular docking rack 411 through the fan-shaped nozzle 2 412 to prevent dust from escaping into the circular unloading rack 423 synchronously with the forward transportation of the magnesium ingot. As the magnesium ingot is pushed from the feeding trough to the circular docking rack 411 , the high-pressure water curtain can also clean the debris and dust attached to the surface of the magnesium ingot, so as to prevent the grinding debris attached to the surface of the magnesium ingot from becoming a "micro-crack source" or a stress concentration point that affects the interface bonding of subsequent welding, electroplating and other processes and the normal fatigue process of the structural parts during actual use. Until the magnesium ingot is completely transported to the circular unloading rack 423, the vertical section of the L-shaped sealing plate 431 can ensure that the front end opening of the circular unloading rack 423 is always in a closed state during the forward transportation of the magnesium ingot. At this time, the connecting plate and the circular unloading rack 423 are driven upward by the hydraulic cylinder 2 422, and the circular unloading rack 423 then drives the The corresponding magnesium ingot and the lower sealing plate 424 move up synchronously. At this time, the upper sealing plate 413 can stably close the rear end opening of the upper return type unloading rack 423, and the front sealing plate 432 can stably close the front end opening of the upper return type unloading rack 423. The lower sealing plate 424 that moves up synchronously will gradually and stably close the front end opening of the corresponding return type docking rack 411 until the return type unloading rack 423 moves to the highest point. At this time, the push plate 2 415 is just aligned with the corresponding magnesium ingot and the front and rear ends of the return type unloading rack 423 are still in a closed state. Then, the front sealing plate 432 is driven downward by the electric push rod 433 to release the closure of the front end opening of the return type unloading rack 423, and the push plate 2 415 is driven forward by the multi-stage cylinder 2 414 to push the corresponding polished magnesium ingot to be unloaded, wherein the water collection tank 2 64 and the drain outlet 2 66 can collect and discharge the water flow containing debris and dust sprayed by the fan-shaped nozzle 2 412.

[0049] The above-mentioned operation method can realize the automatic closure of the feed port and the discharge port during the loading and unloading of the magnesium ingot, so that the entire magnesium ingot grinding process is in a closed environment, and cooperates with the debris adsorption equipment to completely prevent the dust from escaping when the material is in and out. At the same time, the circular support bracket 223 and the surface of the magnesium ingot after grinding are immediately and comprehensively sprayed and cleaned to efficiently remove the residual debris, which not only avoids the residual debris in the circular support bracket 223 from scratching the magnesium ingot, but also avoids the grinding debris attached to the surface of the magnesium ingot from becoming a "micro-crack source" or stress concentration point affecting the interface bonding of subsequent welding, electroplating and other processes and the normal fatigue process of the structural parts during actual use. At the same time, in conjunction with a fully enclosed grinding environment without debris and dust leakage, the secondary attachment of the escaped debris is also blocked, which significantly improves the product reliability and processing yield in high-load application scenarios.
