Description

Technical Field

[0001] The invention relates to the technical field of rotor forming equipment, and in particular to a motor cast copper rotor forming equipment and a casting method. Background Art

[0002] With the advancement of technology, the requirements for electric spindles are getting higher and higher, requiring higher speeds and greater power to meet work needs. The open slot rotors of commonly used electric spindles are mostly made of open slot aluminum. When the rotors and short-circuit rings made of aluminum exceed the allowable speed value of their own rigidity, the electric spindle will creep or crack, thereby affecting normal work. Brass with higher material rigidity must be used to meet normal operation needs. Brass has a high melting point and is easily oxidized when the temperature difference changes greatly. Although there are many methods for manufacturing electric spindle rotors using brass, none of them can meet the requirements of high-speed normal operation of the electric spindle. Finding a low-cost and short-time casting method for the rotor has always been a basic requirement of technicians in this field.

[0003] A device for producing high-efficiency copper rotors for AC induction motors with announcement number CN109070202A includes: a hydraulic injection cylinder and an injection piston, which inject molten copper into a steel laminate stack; a first main board, which holds a gate cavity and a gate mold plate; a second main board, which holds an adjustable core length section, an intermediate mold plate, a rear cavity, an end mold plate, a hydraulic ejector cylinder and an ejector piston rod; a moving main board, which is combined with the second main board; and an end main board, which includes a hydraulic locking cylinder and a locking cylinder rod to lock the mold group by pushing the moving main board.

[0004] A casting method for an open-slot copper rotor of an electric spindle with announcement number CN103949611B includes making a sand mold, drying, pouring, cooling and sand cleaning, and the specific steps are as follows: making a sand mold, stacking a plurality of rotor sheets with cage bar holes in sequence on the outside of a core shaft in the middle of a sand box, pressing a press sleeve on the stacked rotor sheets, inserting a round rod with a diameter smaller than the cage bar holes into the cage bar holes, twisting the stacked rotor sheets, and then locking them with nuts, a pouring port at the upper end of the pouring channel is set at the upper end of the sand box, the pouring port is connected to a pouring cavity outside the rotor sheet, and the sand box is filled and compacted with sand between the outside of the pouring cavity and the sand box.

[0005] Based on the above scheme, most casting machines add the heated material into the stock assembly through the external power wall. Since the funnel scooping material cannot be accurately quantified, the material collected in the stock assembly cannot be determined. In the subsequent injection mold, due to the consistent mold space, overflow will occur when there is more material during injection, and the mold will not be able to be filled when there is less material. When the processing is completed, the remaining residue will be adsorbed in the stock assembly. Although some devices finally use ejection to discharge the material, they cannot be completely removed when there are too many residues. Summary of the invention

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0038] First embodiment

[0039] The present invention provides Figures 1 to 10The motor cast copper rotor forming equipment shown in the figure includes a body 1, a hydraulic component 2, a motion component 3 and a storage component 4. A second chute 9 is opened on the right side of the body 1. A support plate 10 is slidably connected inside the second chute 9, and the upper surface of the support plate 10 is fixedly connected to the bottom surface of the air supply component 8. Four springs 11 distributed in a rectangular shape are arranged between the bottom surface of the support plate 10 and the second chute 9, and each spring 11 is in a compressed state. Under the action of the spring 11, the air supply component 8 can be restored to its original position after completing the work, thereby achieving the purpose of resetting. The air supply component 8 includes a fan 801. When the fan 801 is powered on Afterwards, it is made to operate in the forward direction to generate wind force, thereby achieving the purpose of air delivery. When it rotates in the reverse direction, it can generate suction force, so that the components can be quickly reset. The output end of the fan 801 is connected to the first air storage bin 802, and the first air storage bin 802 is connected to the lower ends of the four second air inlet pipes 503. The upper end of the first air storage bin 802 is connected to the first air inlet pipe 803, and the upper end of the first air inlet pipe 803 is connected to the extrusion plate 7. The first air storage bin 802 can transmit the gas to the first air inlet pipe 803 and the second air inlet pipe 503 respectively, and the gas direction is vertically upward, so that the first air inlet pipe 803 can take in air first.

[0040] The upper surface of the body 1 is provided with a material storage component 4. Through the mutual cooperation of the hydraulic component 2, the motion component 3 and the material storage component 4, a complete motor cast copper rotor forming operation line can be formed, which can complete different tasks at the same time, and the work can be carried out simultaneously, which greatly improves the work efficiency. At the same time, when maintenance is required, the whole can be directly maintained, which greatly improves the maintenance efficiency. The material storage component 4 includes a support plate 401, and a first slide groove 402 is opened inside the support plate 401. The first slide groove 402 is internally slidably connected to the first extrusion plate 403. The inner top wall of the first slide groove 402 and the upper surface of the first extrusion plate 403 can Four cavities are formed, and gas can be filled inside the cavities to increase the resistance encountered by the second extrusion plate 405 when it rises, thereby shortening the rising distance with the same thrust. Four air inlets 404 for circular discharge are provided on the bottom surface of the first extrusion plate 403. The second extrusion plate 405 is slidably connected to the inside of the first extrusion plate 403. Through the mutual cooperation of the first extrusion plate 403 and the second extrusion plate 405, the purpose of pushing the material twice can be achieved. The first pushing can push the material to the surface of the first extrusion plate 403, so that the second extrusion plate 405 contacts the lower mold 305, avoiding the material from entering the middle of the lower mold 305 during the second pushing.

[0041] The inner wall of the first slide groove 402 is provided with four adjustment components 5 distributed in a rectangular shape. The adjustment component 5 can adjust the amount of gas filled according to the amount of material added. The more material there is, the more internal gas can be formed in four cavities by the corresponding inner top wall of the first slide groove 402 and the upper surface of the first extrusion plate 403. The greater the resistance encountered by the first extrusion plate 403 when rising, the correspondingly reduced rising distance, thereby reducing the material pushed into the mold to avoid the situation of excessive material addition and overflow. A limiting cylinder 6 is provided between the side surfaces of the four adjustment components 5 that are close to each other. An extrusion plate 7 is slidably connected inside the limiting cylinder 6, and the upper surface of the extrusion plate 7 is in contact with the bottom surface of the second extrusion plate 405. The inner bottom wall of the limiting cylinder 6 and the bottom surface of the extrusion plate 7 can form a cavity. When the cavity is filled with gas, the extrusion plate 7 can drive the second extrusion plate 405 to move upward, thereby achieving the purpose of automatic adjustment. An air supply component 8 is provided below the four adjustment components 5. The air supply component 8 can supply air to the adjustment component 5, so that the gas inside the adjustment component 5 increases and expands, so that the first extrusion plate 403 rises, thereby achieving the purpose of thorough injection molding.

[0042] The adjustment component 5 includes a second gas storage bin 501, which is filled with gas. When the first push plate 502 moves, it can push the internal gas to circulate, so that the gas enters the cavity above the first extrusion disk 403, so that the internal gas increases. The interior of the second gas storage bin 501 is slidably connected with the first push plate 502 and the second air inlet pipe 503. The second air inlet pipe 503 is connected to the first gas storage bin 802, and the gas can be introduced into the second gas storage bin. The upper surface of the first push plate 502 is provided with an air guide pipe 504, and the upper end of the air guide pipe 504 is connected to the air inlet 404. When the second push plate 506 moves downward, it can compress the gas below the second push plate 506, so that the gas passes through in sequence. The air passes through the first through groove 505 and the air guide pipe 504 into the gap above the first extrusion disk 403, so that the internal gas increases and the internal pressure increases accordingly, so that the resistance gradually increases when the position of the first extrusion disk 403 is adjusted later. Four first through grooves 505 arranged in a circle are opened at the lower part of the outer surface of the air guide pipe 504. The outer surface of the air guide pipe 504 is slidably connected with a second push plate 506. The bottom surface of the second push plate 506 is provided with two symmetrical support rods 507, and the lower ends of the two support rods 507 pass through the first push plate 502 and are connected to the second air intake pipe 503. When the second air intake pipe 503 descends with the second extrusion disk 405, under the action of the support rod 507, it can synchronously drive the second push plate 506 to move.

[0043] A support frame 12 is provided on the outer surface of the body 1. The support frame 12 can combine the body 1 and the hydraulic assembly 2 together, making it more convenient to use. The hydraulic assembly 2 is arranged above the support frame 12. The hydraulic assembly 2 can freely adjust the position of the upper mold 203, so that the upper mold 203 and the lower mold 305 are spliced ​​together, so that the mold is sealed to avoid material overflow during injection molding. The hydraulic assembly 2 includes a hydraulic cylinder 201, and a positioning plate 202 is provided at the output end of the hydraulic cylinder 201. The bottom surface of the positioning plate 202 is provided with an upper mold 203, and the bottom surface of the upper mold 203 is provided with two symmetrical extrusion blocks 204. Four rectangularly distributed positioning columns 205 are provided between the inner top wall of the support frame 12 and the upper surface of the body 1, and each positioning column 205 penetrates the positioning plate 202. The four positioning columns 205 can constrain the position of the positioning plate 202, so that it can rise or fall smoothly, and avoid the upper mold 203 and the lower mold 305 from being misaligned when splicing when adjusting the position, thereby affecting subsequent processing.

[0044] The motion component 3 is arranged on the upper surface of the body 1. The motion component 3 can freely adjust the position of the lower mold 305, which can make it more convenient to unload materials. At the same time, the lower mold 305 is far away from the support frame 12 and has a relatively open position, which is more convenient to replace a new mold. The motion component 3 includes a slide rail 301. The inner sliding connection of the slide rail 301 is provided with a motion plate 302. The upper surface of the motion plate 302 is provided with a slideway 303. Two symmetrical cylinders 304 are provided between the body 1 and the motion plate 302. The two cylinders 304 are more stable when in use. At the same time, when one of them is damaged, it does not affect the use. Under the action of the cylinder 304, the position of the lower mold 305 can be freely adjusted. When the mold needs to be replaced, the cylinder 304 is started to drive the lower mold 305 away from the support frame 12, so that the space around the lower mold 305 becomes larger, making it more convenient to replace it and preventing replacement. In order to prevent collision, the slide 303 is internally slidably connected with two symmetrical lower molds 305, and multiple lower molds 305 are arranged according to different sizes, and the corresponding lower molds 305 can be replaced according to specific processing requirements. Two symmetrical limiting grooves 306 are provided between the upper surface of each lower mold 305 and the upper surface of the slide 303, and each limiting groove 306 is adapted to the extrusion block 204, and the side walls of the two limiting grooves 306 close to each other are inclined. When the extrusion block 204 follows the positioning plate 202 to descend and is inserted into the limiting groove 306, the interaction between the inclined surface and the extrusion can make the two lower molds 305 close to each other, thereby achieving the purpose of mold matching, and a second through groove 307 is provided on the bottom surface of the moving plate 302, and the second through groove 307 runs through the slide 303, and the inner wall of the second through groove 307 is provided with a template 308.

[0045] In actual use, the two cylinders 304 are started to pull the moving plate 302 to drive the two lower molds 305 away from the support frame 12, and the corresponding lower molds 305 are replaced according to the processing requirements. After the replacement is completed, the material heated to melt is put into the storage component 4 through the external power arm. Under the gravity of the material, the second extrusion plate 405 moves downward, and the extrusion plate 7 moves downward along the trajectory of the limit cylinder 6. Under the action of the first air inlet pipe 803, the first air storage bin 802 and the fan 801 below can be driven to move downward. Under the action of the first air storage bin 802, the four The second air inlet pipe 503 descends, and under the constraint of the support rod 507, it drives each second push plate 506 to move downward along the trajectory of the second air storage bin 501, so that the second push plate 506 pushes the air, and the gas passes through the first through groove 505 and the air guide pipe 504 in turn into the gap between the first extrusion plate 403 and the first slide groove 402, so that the internal gas increases, and the air pressure in the gap is correspondingly enhanced, which increases the resistance of the first extrusion plate 403 during the rising process, thereby affecting the rising distance of the first extrusion plate 403, reducing the material entering the lower mold 305, and avoiding overflow.

[0046] When too much material enters the material storage component 4, under the gravity of the material, the second extrusion plate 405 moves downward a longer distance, pushing the extrusion plate 7 to move downward a longer distance along the trajectory of the limiting cylinder 6. Under the action of the first air inlet pipe 803, the first air storage bin 802 and the fan 801 below can be driven to move downward a longer distance. Under the action of the first air storage bin 802, the four second air inlet pipes 503 are pulled to descend a longer distance. Under the constraint of the support rod 507, each second push plate 506 is driven to move downward a longer distance along the trajectory of the second air storage bin 501, so that more air is pushed by the second push plate 506, and the gas passes through the first through groove 505 and the air guide pipe 504 in turn into the gap between the first extrusion plate 403 and the first slide groove 402, so that the internal gas increases again, and the air pressure in the gap increases again accordingly, so that the resistance of the first extrusion plate 403 increases again during the rising process, and then the rising distance of the first extrusion plate 403 is reduced, so that the material entering the lower mold 305 is reduced again, and overflow is avoided.

[0047] Then, the slide rail 301 is started to drive the moving plate 302 to move to the right, so that the second through slot 307 and the material storage component 4 overlap, in preparation for subsequent feeding, and then the upper hydraulic cylinder 201 is started to push the positioning plate 202 and the upper mold 203 to move downward, so that the upper mold 203 contacts the two lower molds 305 below, and at the same time, the two extrusion blocks 204 are inserted into the limiting grooves 306. Under the interaction of the inclined surface and the extrusion, the two lower molds 305 can be brought close to each other, so as to achieve the purpose of mold matching. When the preparation work is completed, the fan 801 below is started to rotate forward to generate wind force to enter the first air storage bin 802. The gas will pass through the first air inlet pipe 803 and the second air inlet pipe 503 respectively. When the gas When passing through the first air inlet pipe 803, under the action of wind force, the second extrusion plate 405 can be pushed to gradually rise, so that the upper material gradually spreads to the surface of the first extrusion plate 403, and then the second extrusion plate 405 contacts the bottom surface of the template 308 to prevent the material from being injected from the center. When the gas enters the second air storage bin 501 through the second air inlet pipe 503, under the action of the gas, the first push plate 502 can be pushed to gradually move upward. Under the push of the air guide pipe 504, the first extrusion plate 403 moves upward. Due to the strong air pressure in the four cavities above the first extrusion plate 403, the rising distance of the first extrusion plate 7 is reduced, thereby preventing excess material from above from entering the mold and causing overflow.

[0048] When the material entering the material storage component 4 is relatively small, under the weight of the material, the downward movement distance of the second extrusion plate 405 is reduced, and the downward movement distance of the extrusion plate 7 is reduced along the trajectory of the limiting cylinder 6. Under the action of the first air inlet pipe 803, the downward movement distance of the first air storage bin 802 and the fan 801 below can be driven to reduce. Under the action of the first air storage bin 802, the four second air inlet pipes 503 are pulled to reduce the downward distance. Under the constraint of the support rod 507, each second push plate 506 is driven to move downward along the trajectory of the second air storage bin 501. The air pushed by the second push plate 506 is reduced, and the gas passes through the first through groove 505 and the air guide pipe 504 in turn into the gap between the first extrusion plate 403 and the first slide groove 402, so that the internal gas increases slightly, and the air pressure in the gap increases slightly accordingly, so that the resistance of the first extrusion plate 403 during the rising process increases slightly, and then the distance of the first extrusion plate 403 when rising increases, so that more material enters the lower mold 305, and the situation of insufficient material is avoided.

[0049] After the material inside the mold has been cooled, the motion component 3 is started to move the processed workpiece to the unloading position. At the same time, when the second through groove 307 and the material storage component 4 are misaligned, the excess residual material can be cut off, and then the fan 801 is turned over to generate suction to recover the generated gas. Since the first extrusion disk 403 is squeezed by the gas, it can be quickly reset first, so that the first extrusion disk 403 quickly hits the limiting cylinder 6 below to cause itself to vibrate violently, thereby causing the remaining residual material to detach from the surface of the first extrusion disk 403. The more residual material there is, the faster the recovery speed of the corresponding first extrusion disk 403 is, and the greater the impact is, so as to avoid the situation where the residual material is adsorbed too much and cannot be completely removed. Subsequently, under the suction of the fan 801, the gas inside the device is gradually reduced, and under the action of gravity and suction, the second extrusion disk 405 is reset to prepare for the next processing.

[0050] Second embodiment

[0051] The present invention also provides a casting method for a motor copper rotor forming device, and the specific operation method steps are as follows:

[0052] S1. First, the heated material is put into the material storage assembly 4 through the external power arm, and the second extrusion plate 405 moves downward under the action of gravity;

[0053] S2. Secondly, the gas inside the space formed by the first extrusion plate 403 and the first chute 402 is increased by adjusting the component 5, so that the resistance of the first extrusion plate 403 when rising is increased and the rising distance is reduced, thereby avoiding the situation where excessive addition of material causes overflow;

[0054] S3, then move the two lower molds 305 to a suitable position through the moving assembly 3, so that the second through slot 307 is located directly above the first extrusion plate 403, and start the hydraulic cylinder 201 to combine the upper mold 203 and the lower mold 305 together, in preparation for the subsequent injection of materials;

[0055] S4. Finally, the air supply component 8 is used to raise the second extrusion disk 405 and then the first extrusion disk 403, thereby completing the purpose of injection molding. After cooling, the air supply component 8 is evacuated. Since the first extrusion disk 403 encounters greater resistance when rising, it can be reset and hit the surface of the limiting cylinder 6 before the second extrusion disk 405. Then, the residual material attached to the surface of the first extrusion disk 403 and the second extrusion disk 405 is vibrated and separated, preparing for the next processing.
