Description

Technical Field

[0001] This invention relates to the field of progressive die technology, specifically to a film sheet stacking and rewinding device. Background Technology

[0002] Progressive dies (also called continuous dies) consist of multiple stations, each sequentially linked to complete different processes. A series of different stamping operations are completed in one stroke of the press. After one stroke, the press feeder moves the material forward at a fixed step distance. Thus, multiple processes can be completed on a single die, typically including punching, blanking, bending, trimming, and deep drawing. Motor stators are usually formed by stacking multiple silicon steel sheets. This material effectively reduces eddy current losses and hysteresis losses, improving motor efficiency. However, the silicon steel sheets used in electronic stators have different shapes... In cases of special or thin single-piece thickness, progressive die stamping is usually used. Progressive dies typically use strip material as raw material and can use an automatic stacking structure to rivet multiple stacks together sequentially during the stamping process. The specific process is as follows: At specific positions of the stator stacks, stacking points with specific geometric shapes are punched out. The upper part of the stacking point is a concave hole, and the lower part is a convex shape. At the blanking station, the convex part of the stacking point of the previous stack precisely coincides with the concave hole of the stacking point of the next stack. Under the pressure of the upper die, the two stacks generate friction in the die, thereby achieving stacking and riveting. When using strip stamping to form laminations, there are certain limitations on the width of the strip. Usually, the strip width needs to be greater than the stator diameter to form the laminations in one piece. However, since the laminations are usually ring-shaped, a lot of waste is generated during stamping due to the holes in the middle of the laminations, resulting in high production costs. When producing large and medium-sized stators, a single lamination is usually divided into multiple loose pieces, and each segment of loose pieces can only form a part of the stator shape. After splicing the loose pieces, a complete lamination can be formed, reducing material costs and increasing productivity. However, when the segmented laminations are vertically stacked and riveted, only a part of the stator shape can be formed. Subsequent manual splicing and welding are required to weld the parts of the stator that make up the loose pieces together to form and fix the stator. This process involves many steps and is quite inconvenient. Summary of the Invention

A motor box is fixedly connected inside the connecting housing, and a servo motor is installed inside the motor box. The motor shaft of the servo motor is fixedly connected to a transmission gear, and the gear teeth of the transmission gear mesh with the gear teeth on the outer wall of the toothed ring.

[0008] Furthermore, the top surface of the synchronizing ring is provided with multiple circumferentially arranged sliding grooves, and each of the multiple sliding grooves has an arc-shaped abutment that is slidably engaged inside. Each abutment is fixedly connected to one end of an adjacent sliding groove with a return spring.

[0009] Furthermore, the connecting shell is fixedly connected to the main hydraulic cylinders on both sides, and two arc-shaped pressure plates are provided inside the connecting shell. Support rods are fixedly connected to the center of the outer arc surface of the two arc-shaped pressure plates, and one end of each support rod is fixedly connected to the movable end of the two main hydraulic cylinders.

[0010] Furthermore, multiple guide grooves are provided on the inner arc surfaces of multiple blocks, and a sliding hole is provided at one end of each guide groove.

A U-shaped clamping block is fixedly connected to one side of each of the multiple push rods, and the movable ring is slidably sleeved between the two arms of the multiple clamping blocks.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. By using a narrow strip of material and a progressive die to punch out loose pieces, and then using a rotary mechanism to support the loose pieces, the loose pieces are naturally riveted together during the stacking process, forming a whole. Then, the rotary mechanism is used to bring the stacked loose pieces together to form a stator, and the stator is secured with fasteners. The stator then falls into the fixed shell and is supported by two rubber plates to reduce the impact force of falling. Then, the auxiliary hydraulic cylinder is activated to drive the two clamping plates to detach from the stator, so that the stator falls into the conveyor belt for transportation. In this way, the stator composed of loose pieces can be automatically formed, improving production efficiency.

[0015] 2. The rotation angle of the synchronous ring is adjusted by the drive motor, synchronous pulley, and synchronous toothed belt, and the rotation angle of the toothed ring is adjusted by the servo motor and transmission gear. When the synchronous ring and the toothed ring rotate synchronously, multiple support arms remain stable and rotate around the center of the synchronous ring, thereby adjusting the angle of multiple magnetic sheets. The magnetic sheets are positioned below the material outlet to attract and fix the loose sheets and support them. Then, when the loose sheets are separated from the material strip during stamping, they are stacked and automatically riveted during the stamping process. The position of the magnetic sheets below the material outlet is changed by adjusting the angle of the toothed ring and the synchronous ring. 3. By starting the electric push rod, the moving ring is moved upward, causing the moving ring to drive multiple push rods to abut against the buckle strips in the adjacent storage box and enter the upper guide groove. The two arms of the U-shaped buckle strip are positioned by the two pressing plates in the adjacent guide groove. Then, when the moving ring resets, the multiple push rods reset simultaneously, and the buckle strips in the storage box are abutted against the discharge port again by the adjacent pressing springs. 4. After multiple magnetic sheets are stacked to a certain height, the two main hydraulic cylinders are activated to drive the two arc-shaped pressure plates to move towards each other. The two arc-shaped pressure plates press multiple blocks to form a ring, gathering the loose pieces on the multiple magnetic sheets into a ring. At the same time, the buckle in the guide groove can be pressed into the connected notch on two adjacent loose pieces by the pressing plate. When the two arc-shaped pressure plates close into a circle, the arc-shaped pressure plates press multiple sliding rods to drive the slider to move. The slider moves away from the two adjacent pressing plates, so that the pressing plate is pressed against the U-shaped buckle and deformed according to the notch shape, so that the buckle is fixed at the notch of the loose piece, thereby forming the stator.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-9 In this embodiment of the invention, a film sheet stacking and rewinding device includes a lower mold 100, and the lower mold 100 has a discharge port 101, comprising: The assembly includes a connecting shell 200, a fixed shell 300, and a rotary mechanism 400 capable of adjusting the material dropping position. The connecting shell 200 is fixedly connected to the lower mold 100 and has a circular through-hole inside. The fixed shell 300 is fixedly connected to the lower part of the connecting shell 200, and also has a circular through-hole inside. The fixed shell 300 and the connecting shell 200 are internally connected. A rectangular groove is formed on the bottom surface of the fixed shell 300, and a conveyor belt 330 is installed inside the rectangular groove. A sleeve 310 is fixedly fitted inside the fixed shell 300, and two pads 311 are fixedly connected to the inner side wall of the sleeve 310. Auxiliary hydraulic cylinders 320 are fixedly connected to opposite sides of the fixed shell 300, and clamping plates 321 are fixedly connected to the movable ends of the two auxiliary hydraulic cylinders 320. Both are movably engaged between two pads 311, and the bottom ends of both clamping plates 321 are fixedly connected to rubber plates 322. The rotating mechanism 400 is located inside the connecting shell 200. The rotating mechanism 400 includes two arc-shaped guide rails 410 arranged vertically in sequence, and both arc-shaped guide rails 410 are fixedly sleeved inside the connecting shell 200. The upper arc-shaped guide rail 410 is rotatably sleeved with a synchronous ring 420, and the bottom surface of the synchronous ring 420 is rotatably connected to multiple rotating shafts 450 arranged in a circle. The bottom ends of the multiple rotating shafts 450 are fixedly connected to support arms 451, and one end of each support arm 451 is provided with a magnetic sheet 452. The bottom surfaces of the multiple magnetic sheets 452 are fixedly connected to multiple limiting rods 453, and the limiting rods 453 are slidably sleeved inside adjacent circular holes.

[0020] Specifically, the lower die 100 is the lower die part of the progressive die, and has a blanking port 101. When the material strip is located at the blanking port 101, the progressive die punches the material strip and pushes the formed pieces away from the material strip from the blanking port 101, so that the pieces fall onto a single magnetic sheet 452 and are attracted and positioned by the magnetic sheet 452. Then, the pieces formed by subsequent punching are stacked on the magnetic sheet 452 in sequence, and the stacked pieces are naturally riveted together due to their own riveting structure. After the pieces on the magnetic sheet 452 are riveted and stacked to a certain height, the synchronous ring 420 can be rotated to drive multiple limit rods 453 to rotate synchronously, thereby replacing the magnetic sheet 452 located below the blanking port 101, so that the material from the lower die 100 can continue to be stacked and riveted on the new magnetic sheet 452. After the materials on plate 52 reach the appropriate height, the stacked pieces on all magnetic sheets 452 naturally form a ring-shaped stator. After fixing the stator shape, multiple rotating shafts 450 are rotated and offset, causing multiple support arms 451, along with limit rods 453 and magnetic sheets 452, to detach from below the stator. The stator then naturally falls into the sleeve 310 of the fixed shell 300. The two pads 311 and two clamping plates 321 inside the sleeve 310 can be spliced ​​into a ring. The stator is buffered by contacting the rubber plate 322. Then, the controller starts two auxiliary hydraulic cylinders 320 to drive the two clamping plates 321 to detach from the pads 311, so that the stator falls onto the conveyor belt 330 and is transported to the next process. This can automatically process the stator into shape and reduce material belt constraints.

[0021] Example 1

[0022] like Figures 3-6 As shown, in this embodiment, a communication port is provided on one side of the connecting shell 200, and a drive box 210 is fixedly connected to one side of the connecting shell 200 via a mounting bracket. A drive motor is installed inside the drive box 210, and a synchronous pulley 211 is fixedly connected to the motor shaft of the drive motor. Multiple gear teeth are fixedly connected to the outer wall of the synchronous ring 420, and a synchronous toothed belt 212 is rotatably sleeved between the synchronous pulley 211 and the outer wall of the synchronous ring 420. Multiple return springs are fixedly connected between multiple magnetic sheets 452 and adjacent support arms 451. The lower arc... A toothed ring 460 is rotatably sleeved inside the guide rail 410, and the inner and outer walls of the toothed ring 460 are provided with gear teeth. Multiple support arms 451 are fixedly connected to multiple gear teeth at their other ends, and the gear teeth at the other ends of the multiple support arms 451 mesh with the gear teeth on the inner wall of the toothed ring 460. A motor box 220 is fixedly connected inside the connecting housing 200, and a servo motor is provided inside the motor box 220. The motor shaft of the servo motor is fixedly connected to a transmission gear 221, and the gear teeth of the transmission gear 221 mesh with the gear teeth on the outer wall of the toothed ring 460.

[0023] In this embodiment, the controller starts the drive motor, which drives the synchronous ring 420 to rotate through the synchronous pulley 211 and the synchronous toothed belt 212, thereby facilitating the adjustment of the rotation angle of the synchronous ring 420. The controller also starts the servo motor, which drives the toothed ring 460 to rotate through the transmission gear 221, thereby causing the toothed ring 460 to deflect multiple support arms 451, thereby adjusting the position of multiple magnetic pieces 452. In the initial state, multiple magnetic pieces 452 are all located inside the synchronous ring 420. When the pieces form the stator, rotating the toothed ring 460 causes multiple magnetic pieces 452 to deflect and disengage from inside the synchronous ring 420, thereby causing the stator to lose support and fall. In this embodiment, when the magnetic sheet 452 is located below the discharge port 101, the magnetic sheet 452 remains close to the discharge port 101 under the push of the return spring to facilitate the receipt of loose pieces. When the loose pieces are stamped, stacked, and riveted in sequence, the magnetic sheet 452 is pressed down by the stamping force and the weight of the loose pieces. Then, when the loose pieces are stacked to a certain height, the top loose piece is stamped and riveted to the loose pieces below. By rotating the synchronization ring 420, the stacked loose pieces are moved away from the discharge port 101 and to the side of the discharge port 101. The stacked loose pieces are attracted by the magnetic sheet 452 and move with the magnetic sheet 452. When 452 moves the stacked loose pieces, the synchronizing ring 420 and the toothed ring 460 rotate synchronously, thereby keeping the support arm 451 stable and moving the new magnetic piece 452 below the discharge port 101, which facilitates the replacement of the magnetic piece 452 below the discharge port 101. A convex plate is provided on one side of the magnetic piece 452, which can abut against the loose pieces. When the magnetic piece 452 and the loose pieces rotate around the center of the synchronizing ring 420, the loose pieces are not easy to move on the magnetic piece 452. When the magnetic piece 452 is separated from the loose pieces, the magnetic piece 452 and the support arm 451 rotate in opposite directions, causing the magnetic piece 452 to be separated from the loose pieces.

[0024] like Figures 3-4 and Figure 6As shown, in this embodiment, the top surface of the synchronizing ring 420 has multiple circumferentially arranged sliding grooves, and each of the multiple sliding grooves has an arc-shaped abutment 430 slidably engaged inside. A return spring 431 is fixedly connected between the abutment 430 and one end of the adjacent sliding groove. The connecting shell 200 has main hydraulic cylinders 230 fixedly connected to opposite sides, and the connecting shell 200 has two arc-shaped pressure plates 231 inside. A support rod is fixedly connected to the center of the outer arc surface of each of the two arc-shaped pressure plates 231, and one end of each support rod is fixedly connected to the movable end of one of the two main hydraulic cylinders 230. Multiple guide grooves are provided on the inner arc surface of multiple abutment blocks 430. A sliding hole is provided at one end of each guide groove. A slider 440 is slidably engaged inside each guide groove. Abutment rod 441 that is slidably sleeved in the adjacent sliding hole is fixedly connected to one side of each slider 440. Two pressing plates 442 are rotatably connected to the other side of each slider 440. Torsion springs are provided at both ends of each pressing plate 442. One end of the torsion spring is fixedly connected to the end of the adjacent pressing plate 442, and the other end is fixedly connected to the side wall of the adjacent slider 440. A tension spring is fixedly connected between one side of the slider 440 and one end of the adjacent guide groove.

[0025] In practice, multiple abutment blocks 430 can be spliced ​​into a ring. The stamped loose pieces have notches at both ends of their outer arc surfaces. After stacking loose pieces of appropriate height on all magnetic pieces 452, the synchronous ring 420 can be rotated to position the gap between two adjacent magnetic pieces 452 below the material outlet 101. This ensures that the tops of all stacked loose pieces are parallel to the bottom surface of the lower die 100. Then, the controller activates two main hydraulic cylinders 230 to drive two arc-shaped pressure plates 231 to press against each other, causing the arc-shaped pressure plates 231 to bring the multiple abutment blocks 430 together to form a ring. The multiple abutment blocks 430 press and position the stacked loose pieces into a ring. U-shaped retaining strips 500 can be placed in each guide groove. The two pressing plates 442 on the slider 440 are located inside the two arms of the U-shaped retaining strips 500. When the multiple abutment blocks 430 press the loose pieces into a ring... The arc-shaped pressure plate 231 presses the abutment rod 441 to move, causing the slider 440 to push the two adjacent pressure plates 442 to rotate away from each other and abut against the U-shaped fastener 500 to deform. The deformed fastener 500 is then stuck at the notch of two adjacent stacked pieces, thereby fixing multiple stacked pieces into a ring-shaped stator. After the two main hydraulic cylinders 230 are reset, the pressure plate 442 is driven to reset by the adjacent torsion spring, and the slider 440 is pulled to reset by the tension spring. Multiple abutments 430 are driven to reset by the adjacent reset spring 431. After the stator is formed, the multiple support arms 451 and magnetic pieces 452 can be deflected by rotating the gear ring 460, causing the magnetic pieces 452 to move below the synchronous ring 420, so that the stator naturally falls into the fixed shell 300. Then, the gear ring 460 drives the multiple support arms 451 to reset, causing the multiple magnetic pieces 452 to be driven by the return spring to re-enter the synchronous ring 420.

[0026] like Figures 5-7As shown, in this embodiment, a plurality of storage boxes 470 are fixedly connected to the bottom surface of the synchronization ring 420. A discharge port is opened at one end of the top surface of the storage box 470, and a plurality of stacked fasteners 500 are provided inside the storage box 470. A plurality of compression springs are fixedly connected to one end of the storage box 470. A U-shaped plate 471 is fixedly connected to one end of the bottom surface of each of the plurality of storage boxes 470. A top rod 472 is slidably engaged between the two arms of the U-shaped plate 471.

[0027] In practice, multiple U-shaped fasteners 500 are stacked inside the storage box 470. The fastener 500 located at one end of the storage box 470 can be positioned at the discharge port of the storage box 470 under the pressure of the compression spring. When it is necessary to insert the fastener 500 into the guide groove above, the fastener 500 can be driven into the guide groove by pushing the push rod 472, and the two pressing plates 442 in the guide groove will be positioned against the two arms of the fastener 500.

[0028] If the total weight of the stator to be produced is relatively light, it can be directly fixed by using the fastener 500 and the loose pieces to be riveted together. If the total weight of the stator is relatively heavy, the shape of the stator can be initially fixed by using the fastener 500. Then, when the stator is transported from the conveyor belt 330 to the next process, the fastener 500 and the loose pieces can be welded together by welding equipment, thereby pre-shaping the stator and facilitating the welding operation.

[0029] Example 2

[0030] Based on Example 1, the movable ring 481 is set to facilitate the automated installation of the buckle 500.

[0031] like Figure 5 As shown, in this embodiment, multiple electric push rods 480 are fixedly connected to the inner wall of the connecting shell 200 via a connecting plate, and a movable ring 481 is provided between the multiple electric push rods 480. The movable ends of the multiple electric push rods 480 are all fixedly connected to the movable ring 481. A U-shaped clamping block 473 is fixedly connected to one side of each of the multiple push rods 472, and the movable ring 481 is slidably sleeved between the two arms of the multiple clamping blocks 473.

[0032] In practice, the controller activates multiple electric push rods 480, which in turn drive the moving ring 481 to move. The moving ring 481 then drives multiple push rods 472 to move upward through the clamping block 473. The push rods 472 then engage the buckle strip 500 with the two pressing plates 442 above. When the moving ring 481 resets, it can drive the multiple push rods 472 to reset as well.
