Description

Technical Field

[0001] The invention relates to the technical field of stamping and forming, and in particular to a vacuum contactor processing device and a processing method thereof. Background Art

[0002] The vacuum contactor is usually composed of an insulating frame, a metal base, a transmission arm, an electromagnetic system, an auxiliary switch and a vacuum switch tube. When the electromagnetic coil passes through the control voltage, the armature drives the arm to rotate, so that the main contact in the vacuum switch tube is connected. After the electromagnetic coil is powered off, the main contact is disconnected due to the action of the opening spring. The vacuum switch tube is composed of an upper cover, a lower cover, a metal bellows and a ceramic tube. The outer shell of the vacuum switch tube is made of 95 porcelain insulation material to form a corrugated porcelain tube. It has the characteristics of large creepage distance, high mechanical strength, heat resistance and impact resistance.

[0003] Among them, the upper cover and the lower cover of the vacuum switch tube are made of tungsten steel, which are generally formed by stamping. When the tungsten steel coil is used for stamping, the formed upper cover and the lower cover need to be removed from the stamping machine manually, which not only has a low safety factor and low efficiency, but also uses an air nozzle to blow them off from the stamping machine, which is not conducive to separately collecting the waste of the stamped upper cover, the lower cover and the middle hole.

[0015] A vacuum contactor processing method, applied to any one of the vacuum contactor processing devices described above, comprises the following steps: S1. Install the tungsten steel coil to the upper end of the conveyor, start the conveyor, pass one end of the tungsten steel coil through the pulley and the lower outer mold, and start the stamping mechanism to stamp the tungsten steel coil into a contactor end cover. During this process, the stamping mechanism cooperates with the unloading mechanism to output the contactor end cover stamped last time out of the stamping mechanism. At the same time, the unloading mechanism cooperates with the accompanying clamping mechanism to clamp both sides of the tungsten steel coil; S2. After the contactor end cover is punched, the punching mechanism cooperates with the waste collection mechanism to blow up the contactor end cover, and at the same time cools the contactor end cover, removes and collects the remaining discs in the middle, and energizes the electromagnetic coil through the cooperation of the feeding mechanism and the power connection adjustment mechanism, so that the electromagnetic coil generates magnetism and the contactor end cover is sucked up; S3. When the contactor end cover moves to the uppermost end, the unloading mechanism and the power connection adjustment mechanism cooperate to disconnect the power to the electromagnetic coil, causing the contactor end cover to fall, and unloading is completed through the unloading mechanism.

[0016] (III) Beneficial effects The vacuum contactor processing device and processing method provided by the present invention have the following beneficial effects: 1. Through the cooperation of the feeding mechanism and the accompanying clamping mechanism, the two ends of the tungsten steel coil can be clamped during the stamping process, so as to avoid the vibration of the tungsten steel coil caused by the lower outer mold lifting the tungsten steel coil with the spring rod during the stamping process, thereby avoiding the deviation of the tungsten steel coil due to vibration and improving the stamping effect of the contactor end cover.

[0017] 2. By setting a waste collection mechanism at the upper end of the stamping mechanism, a certain adsorption effect is achieved on the middle part of the tungsten steel coil during the downward stamping process, so that the middle part of the tungsten steel coil fits more closely with the upper ends of the lower outer mold and the lower inner mold, further improving the stamping effect. At the same time, the small debris between the lower outer mold and the lower inner mold can be removed during adsorption to avoid friction between the tungsten steel coil and the mold during the stamping process, resulting in mold loss and defective products in the stamped contactor end cover.

[0018] 3. The waste collection mechanism sucks air into the internal cavity of the lower inner mold, so that the internal cavity of the lower inner mold is in a negative pressure state, so that the waste disc cut out from the middle part of the contactor end cover can be easily moved downward from the inside of the lower inner mold until it falls into the collection bucket, thereby completing the collection of the waste disc cut out from the middle part of the contactor end cover. At the same time, some fine stamping debris can be sucked into the collection bucket to avoid the waste disc being stuck in the cavity of the lower inner mold later.

[0019] 4. After stamping, the waste collection mechanism arranged at the upper end of the stamping mechanism is used to blow air between the contactor end cover and the lower inner mold, so that the contactor end cover is easier to separate from the upper end of the lower inner mold, and then the electromagnetic coil can more easily suck up the contactor end cover from the upper end of the lower inner mold, and can blow away the small debris that cannot be sucked away between the lower inner mold and the lower outer mold, further improving the effect of removing debris, increasing the service life of the mold, and ensuring the yield rate of stamping.

[0020] 5. After stamping, the waste collection mechanism arranged at the upper end of the stamping mechanism continuously blows air to cool the contactor end cover during its rise, so that the heat generated by the stamping can be quickly dissipated, thereby achieving the contactor end cover being affected by thermal expansion and contraction and becoming smaller. After the electromagnetic coil is powered off and loses its magnetism, it easily falls from the inside of the upper mold to the upper end of the receiving plate, and the unloading is completed in cooperation with the unloading mechanism.

[0021] 6. By setting a feeding mechanism at the front end of the stamping mechanism, cooperating with the power connection adjustment mechanism and the electromagnetic coil, the contactor end covers that have been stamped are automatically collected, automatically turned over, and placed in the receiving barrel to complete the collection of the contactor end covers. The stamped contactor end covers are collected during the stamping stroke to achieve continuous stamping. Compared with the traditional method of manually removing the contactor end covers, it is safer. Compared with using a blowing device to blow the contactor end covers off the lower inner mold, there will be no accumulation of contactor end covers, resulting in the inability to completely blow the stamped contactor end covers off the lower inner mold, which further reduces the wear of the mold and improves the yield of the contactor end covers.

[0027] In this embodiment, the stamping mechanism 1 includes a workbench 11, a column 12, a support platform 13, a mounting seat 14, a cylinder 15, an upper mold 16, a lower outer mold 17, a spring rod 18 and a lower inner mold 19.

[0028] In this embodiment, the contactor end cover 7 is arranged inside the upper mold 16, and the lower ends of the spring rod 18 and the lower inner mold 19 are fixedly connected to the middle of the upper end of the workbench 11. In this embodiment, protrusions are provided on both inner sides of the slider 23, and the protrusions are slidably connected to the inside of the slide groove 22. The lower end of the adjustment seat 24 is fixedly connected to the middle of the upper front side of the workbench 11, and the lower end of the rotating shaft 21 is rotatably connected to the middle of the upper front side of the workbench 11 through a bearing. The rear end of the slider 23 is fixedly connected to the middle of the front side of the upper mold 16.

[0029] Specifically, after the tungsten steel coil to be stamped is placed between the pulley 37 and the lower outer mold 17, the conveying device of the tungsten steel coil is started, and the tungsten steel coil is conveyed to the top of the lower inner mold 19, and the cylinder 15 is started to drive the upper mold 16 to descend. Through the cooperation of the lower outer mold 17, the spring rod 18 and the lower inner mold 19, the tungsten steel coil is stamped to punch out the contactor end cover 7. When the upper mold 16 descends, the slider 23 drives the rotating shaft 21 to rotate, and then drives the receiving plate 29 to rotate forward through the connecting sleeve 27 and the connecting rod 26. At the same time, through the adjusting gear 28 and the adjusting rack 25 at the upper end of the adjusting seat 24, the receiving plate 29 is turned over during the process of rotating to the front side, and the contactor end cover 7 at the upper end of the receiving plate 29 is discharged into the receiving barrel, so that the finished contactor end cover 7 at the upper end of the receiving plate 29 is discharged.

[0030] The power connection and adjustment mechanism 4 includes a bevel gear 1 41, a bevel gear 2 42, a drive shaft 43, a plastic rotating block 44, a metal power connection socket 45, a rotating seat 46 and a carbon brush terminal socket 47.

[0032] Specifically, while the rotating shaft 21 rotates, the bevel gear 1 41 drives the bevel gear 2 42 to rotate, thereby driving the plastic rotating block 44 to rotate through the driving shaft 43, and then driving the upper side of the metal power socket 45 close to the lower end of the carbon brush terminal socket 47. When the upper mold 16 descends to the lowest end and the contactor end cover 7 is stamped out, the metal power socket 45 fits with the carbon brush terminal socket 47, thereby energizing the electromagnetic coil 6, causing the electromagnetic coil 6 to generate magnetism, and the stamped contactor end cover 7 is adsorbed on the lower end of the upper mold 16. In the groove at the end, during the rising process of the upper mold 16, the carbon brush terminal holder 47 remains in contact with the metal power socket 45, so that the electromagnetic coil 6 can continue to adsorb the contactor end cover 7, thereby separating the contactor end cover 7 from the tungsten steel roll and sucking it up. When the upper mold 16 rises to the top, the metal power socket 45 disconnects the contact with the carbon brush terminal holder 47, so that the electromagnetic coil 6 is powered off and loses its magnetism. At this time, the rotating shaft 21 drives the receiving plate 29 to move to the bottom of the upper mold 16 through the connecting rod 26 and the connecting sleeve 27 to complete the material receiving.

[0033] In this embodiment, the accompanying clamping mechanism 3 includes a double-groove pulley 31, a transmission belt 32, a single-groove pulley 33, a threaded rod 34, a threaded cylinder 35, a support plate 36, a pulley 37 and a support rod 38.

[0035] Specifically, the double-groove pulley 31 is driven to rotate by the rotating shaft 21, and then the single-groove pulleys 33 on both sides are driven to rotate by the transmission belt 32, and then the threaded cylinder 35 is driven to descend by the threaded rod 34, so that the pulley 37 at the lower end of the support plate 36 continuously presses the two ends of the tungsten steel coil during the stamping process to prevent the tungsten steel coil from being displaced during stamping.

[0036] In this embodiment, the waste collection mechanism 5 includes an air cylinder 51, a piston 52, a driving rod 53, an air pipe 1 54, a three-way connection 55, a connecting ear 56, a torsion spring rod 57, a cover plate 58, an air pipe 2 59, a one-way air valve 510, a collecting bucket 511, a threaded seat 512 and a sealing ring 513. The interior of the air cylinder 51 is slidably connected to the piston 52, the middle part of the upper end of the piston 52 is fixedly connected to the driving rod 53, the upper end opening of the air cylinder 51 away from the side is fixedly connected to the air pipe 1 54, the rear end opening of the air cylinder 51 is fixedly connected to the three-way connection 55, and the three-way connection 55 is fixedly connected to the three-way connection 55. Connecting ears 56 are fixedly connected to both sides of the upper end, the inner periphery of the upper end opening of the connecting ears 56 is rotatably connected to the outer periphery of both ends of the torsion spring rod 57, the middle outer periphery of the torsion spring rod 57 is fixedly connected to the cover plate 58, the inner periphery of the lower end of the tee 55 is fixedly connected to the air pipe 2 59, the lower end of the air pipe 2 59 is fixedly connected to the one-way air valve 510, the close ends of the one-way air valve 510 are threadedly connected to the upper end openings on both sides of the collecting barrel 511, the upper end of the collecting barrel 511 is threadedly connected to a threaded seat 512, and the inner top wall of the threaded seat 512 is fixedly connected to a sealing ring 513.

[0037] In this embodiment, the lower end of the air cylinder 51 is fixedly connected to the two ends of the middle part of the rear side of the upper end of the workbench 11, the upper end of the threaded seat 512 is fixedly connected to the middle part of the inner top wall of the workbench 11, the front end of the air pipe 54 is fixedly connected to the two sides of the lower end of the lower outer mold 17, the outer periphery of the driving rod 53 is slidably connected to the opening in the middle part of the upper end of the air cylinder 51, the upper front side of the driving rod 53 is fixedly connected to the two sides of the middle part of the rear end of the upper mold 16, and the upper end of the collecting barrel 511 is fitted with the lower end of the sealing ring 513.

[0038] Specifically, during the descent of the upper mold 16, the driving rod 53 drives the piston 52 to slide downward inside the air cylinder 51, and the air is sucked into the cavity between the lower outer mold 17 and the lower inner mold 19 through the air pipe 1 54, forming a certain negative pressure state, so that the middle part of the tungsten steel coil is kept in contact with the upper end of the lower inner mold 19, further improving the stamping effect. After the gas at the lower end of the air cylinder 51 is compressed, it enters the interior of the tee 55. Since the one-way air valve 510 can only exhaust in one direction, the cover plate 58 is opened through the cooperation of the connecting ear 56 and the torsion spring rod 57 to exhaust the gas. At the beginning of the rise of the upper mold 16, the piston 52 rises inside the air cylinder 51 through the driving rod 53, so that the air pipe 1 54 blows air between the lower inner mold 19 and the contactor end cover 7, so that the contactor end cover 7 is separated from the upper end of the lower inner mold 19, and then The electromagnetic coil 6 can suck up the contactor end cover 7 from the upper end of the lower inner mold 19, and in the process of the upper mold 16 continuing to rise, the contactor end cover 7 is continuously blown to reduce the temperature of the contactor end cover 7, thereby causing the contactor end cover 7 to shrink due to the principle of thermal expansion and contraction, so that the contactor end cover 7 can be easily removed from the interior of the upper mold 16 and will not be stuck in the interior of the upper mold 16. At the same time, the cover plate 58 seals the rear end of the tee 55 through the cooperation of the connecting ear 56 and the torsion spring rod 57, and the interior of the collection barrel 511 is evacuated through the air pipe 59 and the one-way air valve 510, so that a negative pressure is formed inside the collection barrel 511, and then the disc cut out from the middle of the contactor end cover 7 is sucked into the interior of the collection barrel 511 from the opening in the middle of the upper end of the lower inner mold 19, thereby completing the collection of the waste disc cut out from the middle of the contactor end cover 7.

[0039] A vacuum contactor processing method, applied to any of the above vacuum contactor processing devices, comprises the following steps: S1. Install the tungsten steel coil to the upper end of the conveyor, start the conveyor, pass one end of the tungsten steel coil through the pulley 37 and the lower outer mold 17, and start the stamping mechanism 1 to stamp the tungsten steel coil into a contactor end cover 7. During this process, the stamping mechanism 1 cooperates with the unloading mechanism 2 to output the contactor end cover 7 stamped last time from the stamping mechanism 1. At the same time, the unloading mechanism 2 cooperates with the accompanying clamping mechanism 3 to clamp both sides of the tungsten steel coil; S2. After the contactor end cover 7 is punched, the punching mechanism 1 cooperates with the waste collecting mechanism 5 to blow up the contactor end cover 7, and cools down the contactor end cover 7 at the same time, removes and collects the remaining discs in the middle, and energizes the electromagnetic coil 6 through the cooperation of the unloading mechanism 2 and the power connection adjustment mechanism 4, so that the electromagnetic coil 6 generates magnetism and the contactor end cover 7 is sucked up; S3. When the contactor end cover 7 moves to the uppermost end, the unloading mechanism 2 and the power adjustment mechanism 4 cooperate to disconnect the power supply to the electromagnetic coil 6, so that the contactor end cover 7 falls, and the unloading is completed through the unloading mechanism 2.

[0040] Working principle: After placing the tungsten steel coil to be stamped between the pulley 37 and the lower outer mold 17, start the conveying device of the tungsten steel coil, and convey the tungsten steel coil to the top of the lower inner mold 19, start the cylinder 15 to drive the upper mold 16 to descend, and through the cooperation of the lower outer mold 17, the spring rod 18 and the lower inner mold 19, the tungsten steel coil is stamped to punch out the contactor end cover 7. When the upper mold 16 descends, the slider 23 drives the rotating shaft 21 to rotate, and then drives the receiving plate 29 to rotate forward through the connecting sleeve 27 and the connecting rod 26. At the same time, through the adjusting gear 28 and the adjusting rack 25 at the upper end of the adjusting seat 24, when the receiving plate 29 rotates to the front side, the receiving plate 29 is turned over to discharge the contactor end cover 7 at the upper end of the receiving plate 29. The finished contactor end cover 7 on the upper end of the receiving plate 29 is unloaded into the material receiving barrel, and at the same time, the double-groove pulley 31 is driven to rotate through the rotating shaft 21, and then the single-groove pulleys 33 on both sides are driven to rotate through the transmission belt 32, and then the threaded cylinder 35 is driven to descend through the threaded rod 34, so that the pulley 37 at the lower end of the support plate 36 continues to press the two ends of the tungsten steel coil during the stamping process to avoid the displacement of the tungsten steel coil during stamping. During the descent of the upper mold 16, the driving rod 53 drives the piston 52 to slide downward inside the air cylinder 51, and the air is sucked into the cavity between the lower outer mold 17 and the lower inner mold 19 through the air pipe 54, forming a certain negative pressure state, so that the middle part of the tungsten steel coil is kept in contact with the upper end of the lower inner mold 19, and the upper end of the lower inner mold 19 is pressed. The effect of stamping is further improved. After the gas at the lower end of the air cylinder 51 is compressed, it enters the interior of the three-way valve 55. Since the one-way air valve 510 can only exhaust in one direction, the cover plate 58 is opened through the cooperation of the connecting ear 56 and the torsion spring rod 57 to exhaust the gas. While the rotating shaft 21 rotates, the bevel gear 1 41 drives the bevel gear 2 42 to rotate, thereby driving the plastic rotating block 44 to rotate through the driving shaft 43, and then driving the upper side of the metal power socket 45 close to the lower end of the carbon brush terminal socket 47. When the upper mold 16 descends to the lowest end and the contactor end cover 7 is stamped out, the metal power socket 45 fits with the carbon brush terminal socket 47, thereby energizing the electromagnetic coil 6, causing the electromagnetic coil 6 to generate magnetism, and the stamped contactor The end cover 7 is adsorbed in the groove at the lower end of the upper mold 16. During the rising process of the upper mold 16, the carbon brush terminal holder 47 remains in contact with the metal power socket 45, so that the electromagnetic coil 6 can continue to adsorb the contactor end cover 7, thereby separating the contactor end cover 7 from the tungsten steel roll and sucking it up. When the upper mold 16 rises to the top, the metal power socket 45 breaks the contact with the carbon brush terminal holder 47, so that the electromagnetic coil 6 loses power and loses its magnetism. At this time, the rotating shaft 21 drives the receiving plate 29 to move to the bottom of the upper mold 16 through the connecting rod 26 and the connecting sleeve 27 to complete the material connection. At the beginning of the rise of the upper mold 16, the piston 52 rises inside the air cylinder 51 through the driving rod 53, so that the air pipe 54 blows air between the downward inner mold 19 and the contactor end cover 7.The contactor end cover 7 is separated from the upper end of the lower inner mold 19, so that the electromagnetic coil 6 can suck up the contactor end cover 7 from the upper end of the lower inner mold 19, and in the process of the upper mold 16 continuing to rise, the contactor end cover 7 is continuously blown to reduce the temperature of the contactor end cover 7, so that the contactor end cover 7 shrinks due to the principle of thermal expansion and contraction, so that the contactor end cover 7 can be easily dropped from the inside of the upper mold 16, and will not be stuck in the inside of the upper mold 16. At the same time, the cover plate 58 seals the rear end of the tee 55 through the cooperation of the connecting ear 56 and the torsion spring rod 57, and the inside of the collection barrel 511 is evacuated through the air pipe 59 and the one-way air valve 510, so that the collection barrel 5 11 forms a negative pressure inside, and then the disc cut out from the middle of the contactor end cover 7 is sucked into the collecting barrel 511 through the opening in the middle of the upper end of the lower inner mold 19, so as to complete the collection of the waste disc cut out from the middle of the contactor end cover 7. By arranging a feeding mechanism 2 at the front end of the stamping mechanism 1, in cooperation with the power-connected adjustment mechanism 4 and the electromagnetic coil 6, the contactor end cover 7 that has been stamped is automatically collected, automatically turned over, and placed in the collecting barrel, so as to complete the collection of the contactor end cover 7. By cooperating with the feeding mechanism 2 and the accompanying pressing mechanism 3, the two ends of the tungsten steel coil can be pressed during the stamping process, so as to avoid the deviation of the tungsten steel coil during the stamping process, thereby improving In order to improve the effect of stamping, a waste collecting mechanism 5 is arranged at the upper end of the stamping mechanism 1, so that in the process of downward stamping, a certain adsorption effect is achieved on the middle part of the tungsten steel coil, so that the middle part of the tungsten steel coil is more closely fitted with the upper ends of the lower outer mold 17 and the lower inner mold 19, and the effect of stamping is further improved. After stamping, the waste collecting mechanism 5 arranged at the upper end of the stamping mechanism 1 is used to first blow air between the contactor end cover 7 and the lower inner mold 19, so that the contactor end cover 7 is more easily separated from the upper end of the lower inner mold 19, and then the electromagnetic coil 6 is more easily sucked up from the upper end of the lower inner mold 19. Secondly, in the process of the contactor end cover 7 rising, the waste collecting mechanism 5 is continuously blown to the space between the contactor end cover 7 and the lower inner mold 19. The contactor end cover 7 is cooled by blowing air, so that the heat generated by stamping of the contactor end cover 7 can be quickly dissipated, thereby realizing that the contactor end cover 7 can be reduced in size due to thermal expansion and contraction. After the electromagnetic coil 6 is powered off and loses its magnetism, it easily falls from the inside of the upper mold 16 to the upper end of the receiving plate 29, and cooperates with the unloading mechanism 2 to complete the unloading, and the waste collection mechanism 5 sucks air into the internal cavity of the lower inner mold 19, so that the internal cavity of the lower inner mold 19 is in a negative pressure state, thereby realizing that the waste disc cut out of the middle part of the contactor end cover 7 can be easily moved downward from the inside of the lower inner mold 19 until it falls into the collection bucket 511, completing the collection of the waste disc cut out of the middle part of the contactor end cover 7.
