Description

Technical Field

[0001] The present invention relates to the field of punching technology, in particular to a large-scale motor punching and cutting device. Background Art

[0002] The motor core is one of the most important components of the motor. It is usually composed of a stator and a rotor. The stator is the non-rotating part and the rotor is the rotating part. Generally, the rotor is located inside the stator. The motor core is often made of silicon steel.

[0003] During the production process, both rotors and stators are usually manufactured by first punching out silicon steel sheets and then stacking several silicon steel sheets to form a cylindrical iron core. However, in the currently common punching devices, the drives of the punching mechanism and the loading and unloading mechanism are generally separated. Multiple drives work simultaneously, driving multiple mechanisms to cooperate in completing the feeding, punching and discharging processes, which consumes a lot of energy. Summary of the Invention

[0004] In order to reduce the setting of the driving mechanism, save energy and reduce energy consumption, the present application provides a large-scale motor punching and cutting equipment.

[0005] This application provides a large-scale motor punching and cutting device, which adopts the following technical solutions:

[0006] A large-scale motor punching and cutting equipment comprises a workbench, on which a loading mechanism, a punching mechanism, a unloading mechanism and a waste processing mechanism are provided. The unloading mechanism comprises a receiving part, a feeding part and a collecting part. A transmission part for driving the receiving part to move back and forth is provided between the punching mechanism and the receiving part. A conversion part for driving the feeding part to rotate is provided between the receiving part and the feeding part. The transmission part comprises a bracket, a swivel, a first rotating rod, a second rotating rod, a third rotating rod and a fourth rotating rod. The swivel is rotatably connected to the bracket, and the two ends of the first rotating rod are respectively rotatably connected to the punching mechanism and the second rotating rod, and the other end of the second rotating rod is fixedly connected to the swivel, and the swivel is fixedly connected to one end of the third rotating rod. The two ends of the fourth rotating rod are respectively rotatably connected to the third rotating rod and the receiving part. The receiving part is arranged tilted, and the bracket is provided with a slide rail adapted to the receiving part.

[0007] By adopting the above technical solution, the loading mechanism is used to transport the silicon steel sheet to the bottom of the punching mechanism for punching. The silicon steel sheet moves with the loading mechanism, so that the punching position of the punching mechanism is the same each time, and the positions of the scraps after punching are basically the same, which is convenient for collecting and reusing the scraps. The unloading mechanism connects the punching mechanism with the unloading mechanism by setting transmission parts and conversion parts. When the punching mechanism is working, it drives the unloading mechanism to work synchronously, reducing the drive setting of the unloading mechanism, so that the punching mechanism and the unloading mechanism share the same drive, which is conducive to saving energy and reducing energy consumption. When the punching mechanism moves in the vertical direction, it drives the first rotating rod and the second rotating rod to rotate, and the angle between the second rotating rod and the third rotating rod remains unchanged, thereby driving the third rotating rod and the fourth rotating rod to rotate, so that the fourth rotating rod pulls the receiving part to move along the slide rail, thereby realizing drive transmission between the punching mechanism and the receiving part.

[0008] Optionally, the conversion part includes a ratchet and several pawls, the material receiving part is fixedly connected to the moving rod, the pawl is rotatably connected to the moving rod along the length direction of the moving rod, the bracket is fixedly connected to the column, the ratchet is rotatably connected to the column, the side of the ratchet away from the column is fixedly connected to a bevel gear, the feeding part is fixedly connected to the transmission rod, and the transmission rod is fixedly connected to a bevel gear pair.

[0009] By adopting the above technical solution, the material receiving part drives the moving rod to perform linear reciprocating motion, the moving rod drives all the pawls to move, and the pawl drives the ratchet to rotate when the moving rod moves forward. When the pawl moves in the opposite direction with the moving rod, the pawl and the moving rod rotate, and the ratchet remains stationary, completing the resetting of the moving rod and the pawl, thereby realizing the one-way conveying drive of the feeding part.

[0010] Optionally, the waste processing mechanism includes a first processing device and a second processing device, the transmission rod is fixedly connected to a first synchronous wheel, the second processing device is fixedly connected to a second synchronous wheel, and a synchronization device is provided between the first synchronous wheel and the second synchronous wheel.

[0011] By adopting the above technical solution, the second processing device is used to transport the scraps outside the punching mechanism. The first synchronous wheel rotates, and the second synchronous wheel is driven to rotate through the synchronous device to complete the driving of the second processing device, further reducing the setting of the driving device, saving energy and reducing energy consumption.

[0012] Optionally, the first processing device includes a lifting member, a rotating member, a pushing member and a stacking member. The lifting member, the rotating member and the pushing member are all arranged inside the workbench. The rotating member includes a disc and two abutment blocks. The abutment blocks are movably inserted into the upper surface of the disc. The workbench is provided with a through hole adapted to the abutment blocks. The lifting member is arranged directly below the through hole. The rotating member is rotatably connected to the workbench. The disc is provided with a circular hole for the lifting member to pass through. The lower end surface of the abutment block is provided with a groove adapted to the lifting member. The pushing member is provided above the disc. A conveying member is provided below the rotating member. The stacking member is provided on the side of the conveying member away from the lifting member.

[0013] By adopting the above technical solution, the lifting part drives the abutment block to move in the vertical direction, so that the abutment block abuts against the punching mechanism to complete the punching of the silicon steel plate. Then the abutment block moves downward with the center wafer scraps produced after punching. After the rotating part rotates, the pushing part pushes the wafer scraps onto the conveying part, and finally they are collected by the stacking part.

[0014] Optionally, the stacking member includes a base plate and a plurality of baffles, the baffles are vertically arranged on the upper end surface of the base plate, and a bending portion is provided above the baffle, which bends in a direction away from the center.

[0015] By adopting the above technical solution, the diameter of the virtual circle formed at the upper end of the baffle is larger than the diameter of the virtual circle formed at the lower end of the baffle, which makes it easier for the center of the circle of the wafer scraps and the center of the circle of the bottom plate to be on the same straight line, making it easier for the wafer scraps to enter the stacked parts.

[0016] Optionally, the loading mechanism includes a moving device and a conveying device, the moving device includes a threaded rod and a conveying platform, the conveying device includes two conveying rollers and two positioning rollers, the conveying rollers and the positioning rollers are both rotatably connected to the conveying platform, the two positioning rollers are vertically arranged at one end of the conveying platform away from the punching mechanism, and the two conveying rollers are vertically arranged at one end of the conveying platform close to the punching mechanism.

[0017] By adopting the above technical solution, the rotation of the conveying roller drives the silicon steel sheet to move along the length direction of the workbench, so that the silicon steel sheet is conveyed to the bottom of the punching mechanism, and the positioning roller fixes the silicon steel sheet, which is beneficial to ensure the stability of the silicon steel sheet.

[0018] Optionally, the collecting piece includes a positioning column and a chassis, the chassis is located at one end of the feeding piece, the positioning column is fixedly connected to the upper end surface of the chassis, the diameter of the upper end of the positioning column is smaller than the diameter of the lower end, and two vertical guide plates are fixedly connected to one end of the feeding piece close to the collecting piece, and the guide plates are bent inward.

[0019] By adopting the above technical solution, the guide plate is conducive to ensuring that the punched finished products enter the collecting piece. The diameter of the upper end of the positioning column is small, which makes it easy for the center hole of the punched finished product to be placed on the positioning column, making it easy to align and stack the centers of all punched finished products.

[0020] Optionally, a stabilizing member is provided at the lower end of the punching mechanism, and the stabilizing member includes two elastic telescopic rods, the lower ends of the elastic telescopic rods are fixedly connected to a pressure plate, and the two elastic telescopic rods are respectively arranged on both sides of the punching mechanism.

[0021] By adopting the above technical solution, the elastic telescopic rod contacts the silicon steel sheet before the lower end of the blanking mechanism, and the two pressure plates fix the silicon steel sheet, which is beneficial to ensure the stability of the silicon steel sheet when the blanking mechanism is blanking.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By setting up a transmission part, the power of the punching mechanism is transmitted to the feeding part, so that the receiving part can transport the punched finished product.

DETAILED DESCRIPTION

[0031] The application will be further described in detail below with reference to all the accompanying drawings.

[0032] The application discloses a large motor punching sheet cutting device. EMBODIMENT

[0033] REFERENCE Figure 1 AND Figure 2 The large motor punching sheet cutting device comprises a workbench 1, and the workbench 1 is provided with a feeding mechanism 2, a blanking mechanism 3, a discharging mechanism 4 and a waste treatment mechanism. The silicon steel plate is conveyed to the blanking mechanism 3 by the feeding mechanism 2 to be blanked, the blanked finished product is transported and collected by the discharging mechanism 4, and the center disc corner waste and the external corner waste generated in the blanking process are respectively collected by the waste treatment mechanism, so that the corner waste can be conveniently recycled and treated.

[0034] REFERENCE Figure 1 AND Figure 2 The feeding mechanism 2 comprises a moving device and a conveying device. The moving device comprises a threaded rod 211 and a conveying table 212. The threaded rod 211 is rotationally connected with the workbench 1. The threaded rod 211 penetrates through the conveying table 212 and is threadedly connected with the conveying table 212. When the threaded rod 211 rotates, the conveying table 212 is driven to displace along the width direction of the workbench 1, so that the silicon steel plate is displaced in the width direction between the blanking mechanism 3.

[0035] REFERENCE Figure 1 AND Figure 2The conveying device includes two conveying rollers 221 and two positioning rollers 222. The conveying rollers 221 and the positioning rollers 222 are both rotatably connected to the conveying platform 212. The two conveying rollers 221 are vertically arranged at one end of the conveying platform 212 close to the punching mechanism 3, and the two positioning rollers 222 are vertically arranged at one end of the conveying platform 212 away from the punching mechanism 3. The conveying rollers 221 rotate to move the silicon steel sheet toward the punching mechanism 3, and the two positioning rollers 222 stabilize and level the silicon steel sheet before conveying to ensure the subsequent punching effect.

[0036] Reference Figure 1 and Figure 3 The punching mechanism 3 includes a moving part 32 and a cutting part 33. The cutting part 33 includes an outer circle cutter 331 and an inner circle cutter 332. The outer circle cutter 331 and the inner circle cutter 332 are coaxially arranged. A number of suction cups 34 are provided between the outer circle cutter 331 and the inner circle cutter 332. The suction cups 34 absorb the finished punched product after punching. When the blanking mechanism 4 moves to the bottom of the punching mechanism 3, the suction of the suction cups 34 is released, causing the finished punched product to fall to the blanking mechanism 4 for transportation.

[0037] Reference Figure 1 and Figure 3 A stabilizing member 31 is provided at the lower end of the punching mechanism 3. The stabilizing member 31 includes two elastic telescopic rods 311. The lower ends of the elastic telescopic rods 311 are fixedly connected to a pressing plate 312. The two elastic telescopic rods 311 are respectively arranged on both sides of the punching mechanism 3. The two elastic telescopic rods 311 are located on both sides of the outer circle cutter 331. When the elastic telescopic rods 311 are in a natural state, the lower end surface of the pressing plate 312 is lower than the lower end of the outer circle cutter 331.

[0038] Reference Figure 1 and Figure 3 When the punching mechanism 3 moves downward, the pressure plate 312 first contacts the silicon steel sheet. The two pressure plates 312 fix the silicon steel sheet on both sides of the outer circle cutter 331, which is beneficial to improve the stability of the silicon steel sheet when the outer circle cutter 331 and the inner circle cutter 332 are punching. The punching mechanism 3 moves further downward, the elastic telescopic rod 311 shortens, and the outer circle cutter 331 and the inner circle cutter 332 punch the silicon steel sheet. At the same time, the suction cup 34 generates suction to adsorb the punched product on the suction cup 34, so that the punched product moves upward with the punching mechanism 3.

[0039] Reference Figure 1 and Figure 2The blanking mechanism 4 includes a material receiving member 41, a material feeding member 42, and a collecting member 43. A transmission member 44 is provided between the blanking mechanism 3 and the material receiving member 41 for driving the material receiving member 41 to move back and forth. The transmission member 44 includes a bracket 441, a swivel 442, a first rotating rod 443, a second rotating rod 444, a third rotating rod 445, and a fourth rotating rod 446. The two ends of the first rotating rod 443 are rotatably connected to the blanking mechanism 3 and the second rotating rod 444, respectively. The swivel 442 is rotatably connected to the bracket 441. When the blanking mechanism 3 moves upward, it drives the first rotating rod 443 to move upward, and the first rotating rod 443 and the second rotating rod 444 rotate, causing the second rotating rod 444 to rotate upward relative to the bracket 441, thereby driving the swivel 442 and the bracket 441 to rotate.

[0040] Reference Figure 1 and Figure 2 The swivel 442 is fixedly connected to one end of the third rotating rod 445, and the two ends of the fourth rotating rod 446 are rotatably connected to the third rotating rod 445 and the material receiving member 41, respectively. When the swivel 442 rotates, the third rotating rod 445 rotates along with the swivel 442, thereby driving the fourth rotating rod 446 to rotate, so that the end of the fourth rotating rod 446 close to the material receiving member 41 moves toward the direction close to the blanking mechanism 3, thereby driving the material receiving member 41 to move toward the direction close to the blanking mechanism 3. The bracket 441 is provided with a slide rail 447 adapted to the material receiving member 41. The material receiving member 41 is arranged at an angle, and the slide rail 447 has a limiting effect on the material receiving member 41, so that the material receiving member 41 moves upward along the slide rail 447 along with the fourth rotating rod 446.

[0041] Reference Figure 1 and Figure 2 The receiving piece 41 moves upward along the slide rail 447, so that the end of the receiving piece 41 away from the fourth rotating rod 446 moves to the bottom of the blanking mechanism 3. At this time, the suction cup 34 (refer to Figure 3 ) disappears, and the punched product falls onto the receiving piece 41 under the action of gravity and moves downward along the receiving piece 41. At the same time, the punching mechanism 3 moves downward, driving the first rotating rod 443, the second rotating rod 444 and the rotating ring 442 to rotate, and then the third rotating rod 445 and the fourth rotating rod 446 rotate. The fourth rotating rod 446 pushes the receiving piece 41 to move downward along the slide rail 447, so that the punched product moves to the feeding piece 42, and at the same time, the punching mechanism 3 performs the next punching on the silicon steel sheet.

[0042] Reference Figure 1 and Figure 4A conversion member 45 for driving the feeder 42 to rotate is provided between the material receiving member 41 and the material feeding member 42. The conversion member 45 includes a ratchet 451 and a plurality of pawls 452. The material receiving member 41 is fixedly connected to a moving rod 453. The pawls 452 are rotatably connected to the moving rod 453 along its length. The bracket 441 is fixedly connected to a column 454. The ratchet 451 is rotatably connected to the column 454. When the moving rod 453 moves downward with the material receiving member 41, the pawls 452 move downward with the moving rod 453. The pawl 452 closest to the ratchet 451 is the first to be inserted into the tooth groove of the ratchet 451. When the moving rod 453 continues to move downward, the pawl 452 drives the ratchet 451 to rotate until the pawl 452 separates from the ratchet 451.

[0043] Reference Figure 1 and Figure 4 As the moving rod 453 continues to move downward, the next pawl 452 is inserted into the tooth groove of the ratchet 451. The next pawl 452 continues to push the ratchet 451 to rotate as the moving rod 453 moves. The side of the ratchet 451 away from the column 454 is fixedly connected to the bevel gear 456. The feeder 42 is the first conveyor belt. The side of the first conveyor belt away from the receiving member 41 is fixedly connected to the first baffle to prevent the blanked products from sliding off the first conveyor belt due to inertia. The feeder 42 is fixedly connected to the transmission rod 455. The transmission rod 455 is fixedly connected to the bevel gear pair. The bevel gear pair meshes with the bevel gear 456. When the ratchet 451 rotates, it drives the bevel gear 456 to rotate, and then drives the bevel gear pair to rotate, completing the drive of the first conveyor belt.

[0044] Reference Figure 1 and Figure 4 When the moving rod 453 moves upward, the pawl 452 contacts the outer edge of the ratchet 451. When the pawl 452 moves with the moving rod 453, the ratchet 451 remains stationary. The pawl 452 rotates upward under the action of the ratchet 451, completing the reset process of the pawl 452 moving to the highest point with the moving rod 453.

[0045] Reference Figure 1 and Figure 2 Two vertical guide plates 433 are fixedly connected to one end of the feeding piece 42 close to the collecting piece 43. The punched product contacts the guide plate 433 under the transportation of the first conveyor belt. The guide plate 433 is bent inward. The closest point of the two guide plates 433 is located above the collecting piece 43. Under the limiting action of the guide plate 433, the center of the punched product and the center of the collecting piece 43 are roughly on the same straight line.

[0046] Reference Figure 1 and Figure 2The collecting piece 43 includes a positioning column 431 and a chassis 432. The chassis 432 is located at one end of the feeding piece 42. The positioning column 431 is fixedly connected to the upper end surface of the chassis 432. The diameter of the upper end of the positioning column 431 is smaller than the diameter of the lower end. The punched finished product is further conveyed, so that the punched finished product is separated from the first conveyor belt. The punched finished product moves downward under the action of gravity, so that the hole in the center of the punched finished product is sleeved on the outside of the positioning column 431. The diameter of the upper end of the positioning column 431 is smaller than the diameter of the hole in the center of the punched finished product, ensuring that the punched finished product can be more conveniently sleeved on the positioning column 431. The collecting piece 43 aligns the center of the punched finished product and stacks them to complete the collection of the punched finished products.

[0047] Reference Figure 2 and Figure 4 The waste treatment mechanism includes a first treatment device 51 (refer to Figure 3 ) and the second processing device 52, the second processing device 52 is a second conveyor belt, the second conveyor belt is fixedly connected to a second baffle on the side away from the blanking mechanism 3 to prevent the scrap from escaping from the second conveyor belt under the action of inertia, the transmission rod 455 is fixedly connected to the first synchronous wheel 521, the second processing device 52 is fixedly connected to the second synchronous wheel 522, and a synchronization device 523 is provided between the first synchronous wheel 521 and the second synchronous wheel 522. When the first synchronous wheel 521 rotates with the transmission rod 455, it is transmitted through the synchronization device 523, so that the second synchronous wheel 522 rotates in the same direction, thereby driving the second conveyor belt to rotate, and the second processing device 52 cuts the outer circle 331 (refer to Figure 3 ) The scraps on the outside are transported and collected.

[0048] Reference Figure 1 and Figure 3 The first processing device 51 includes a lifting member 511, a rotating member 512, a pushing member 513 and a stacking member 514. The lifting member 511, the rotating member 512 and the pushing member 513 are all arranged inside the workbench 1. The rotating member 512 includes a disc 5121 and two abutment blocks 5122. The lower end surface of the abutment block 5122 is provided with a groove compatible with the lifting member 511. The lifting member 511 is used to drive the abutment block 5122 to move in the vertical direction.

[0050] With reference to Figure 1 and Figure 3 , the abutting block 5122 is movably inserted into the upper surface of the disc 5121, when the lower end surface of the abutting block 5122 abuts against the disc 5121, the abutting block 5122 is inserted into the disc 5121 under the action of gravity, the lifting piece 511 continues to move downwards, and the lifting piece 511 moves to below the disc 5121 away from the circular hole. The rotating piece 512 is rotationally connected with the workbench 1, and the pushing piece 513 is arranged above the disc 5121, at this time, the disc 5121 rotates to move another abutting block 5122 to above the lifting piece 511, and the abutting block 5122 supporting the disc edge scrap moves to the side of the pushing piece 513, and the pushing piece 513 works to push the disc edge scrap off the upper end surface of the abutting block 5122.

[0051] With reference to Figure 1 and Figure 3 , the conveying piece 515 is arranged below the rotating piece 512, the conveying piece 515 is a third conveying belt, the stacking piece 514 is arranged on the side of the conveying piece 515 away from the lifting piece 511, the disc edge scrap falls on the surface of the third conveying belt under the action of the pushing piece 513, and the third conveying belt conveys the disc edge scrap to the stacking piece 514 for collection.
