Description

Technical Field

[0001] This invention relates to the field of iron core technology, specifically to an iron core lamination device and its usage method. Background Technology

[0002] The existing single-phase transformer core structure uses a traditional laminated square frame structure, which consists of multiple silicon steel sheets of a certain length and width stacked into a square frame. The wound coil is then fitted into two core columns, and the upper yoke is used to clamp and fix it. During lamination, the silicon steel sheets on the left and right sides of the coil need to be stacked alternately, resulting in an increasing number of silicon steel sheets on the coil and a correspondingly higher lamination height. During lamination, the stacking height of the silicon steel sheets on the left and right sides needs to be constantly adjusted to adapt to the lamination height of the coil. This makes the lamination process cumbersome and slow. To address these problems, a core lamination device and its usage method are proposed. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a core lamination device and its usage method, which solves the problem of low lamination efficiency.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a core lamination device, comprising a base and sliding columns, wherein the sliding columns are fixedly disposed on the top of the base, and a plurality of sliding columns are provided, wherein a sliding plate is slidably connected to the surface of the plurality of sliding columns, a positioning frame is fixedly connected to the top of the sliding plate, a coil assembly is placed inside the positioning frame, storage frames are fixedly connected to both sides of the top of the base via brackets, a cross-stacking mechanism is provided on the top of the base, a stop mechanism is provided on the top of the positioning frame, and a compaction mechanism is provided on the top of the stop mechanism.

[0005] Preferably, the cross-stacking mechanism includes an internally threaded cylinder rotatably mounted on the top of the base. An externally threaded post is threadedly connected to the internal thread of the internally threaded cylinder, and the top of the externally threaded post is fixedly connected to the bottom of the slide plate. A half-gear is fixedly connected to the surface of the internally threaded cylinder. A drive motor is fixedly connected to the top of the base via a bracket. The output shaft of the drive motor is fixedly connected to a reciprocating screw via a coupling, and one end of the reciprocating screw is rotatably connected to the top of the base via a bracket. An elliptical ring frame is provided on the top of the base, and a threaded sleeve matching the reciprocating screw is fixedly connected to the rear side of the elliptical ring frame. Teeth are provided on both the front and rear sides of the inner cavity of the elliptical ring frame. Pusher frames matching the storage frame are fixedly connected to both sides of the elliptical ring frame via brackets.

[0006] Preferably, the stop mechanism includes four L-shaped columns, which are fixedly installed on the front and rear sides of the top of the positioning frame. On the same plane, each of the two L-shaped columns facing away from each other has several guide slots at equal intervals. The surface of each L-shaped column has a storage groove. The inside of the storage groove is slidably connected to an inclined block that matches the guide slot. A second return spring is fixedly connected between the inclined block and the storage groove.

[0007] Preferably, the compaction mechanism includes a handle-shaped sector plate, which is rotatably mounted on the top of an L-shaped column. Both the handle-shaped sector plate and the L-shaped column have threaded positioning grooves on their surfaces, and a bolt is threadedly connected between the two threaded positioning grooves. A limit cover is fixedly connected to one side of the handle-shaped sector plate, and a pressure column is slidably connected inside the limit cover. A third return spring is fixedly connected between the pressure column and the limit cover, and an inclined pressure plate is fixedly connected to the bottom of the pressure column.

[0008] Preferably, the positioning frame is internally threaded with a threaded rod, and several threaded rods are arranged around it. One end of the threaded rod is rotatably provided with a clamping plate that is used in conjunction with the coil assembly.

[0009] Preferably, a limiting slide shaft is fixedly connected to the top of the base, a limiting slide cylinder is slidably connected to the surface of the limiting slide shaft, and the rear side of the limiting slide cylinder is fixedly connected to the front side of the elliptical ring frame.

[0010] Preferably, a plurality of limiting sleeves are fixedly connected at equal intervals around the surface of the internally threaded cylinder, and a limiting rod is slidably connected inside the limiting sleeve, and a first return spring is fixedly connected between the limiting rod and the limiting sleeve.

[0011] Preferably, a ring cover is fixedly connected to the top of the base, and the inner wall of the ring cover has a slot for use with a limiting rod.

[0012] This invention also discloses a method for using a core lamination device, specifically including the following steps: S1, Cross Stacking: Start the drive motor, which drives the reciprocating screw to rotate. The reciprocating screw rotates, and the threaded sleeve on its surface drives the elliptical ring frame, the toothed part, and the pusher to move to the right. The pusher on the right side moves to the right and is pulled out from the storage box. As the elliptical ring frame and the pusher continue to move, the toothed part located on the rear side of the inner cavity of the elliptical ring frame will mesh with the half gear, causing the inner threaded cylinder to rotate half a turn. When the inner threaded cylinder rotates, the outer threaded column will partially retract into the inner threaded cylinder. The descent and retraction of the outer threaded column simultaneously drives the slide plate, the positioning frame, and the coil assembly to move at equal distances, leaving stacking space for the left E stacking in advance. As the elliptical ring frame and the right pusher frame continue to move to the right, the elliptical ring frame will simultaneously drive the left pusher frame into the interior of the left storage box, and push the left E-layer to stack. After stacking, the corresponding threaded sleeve will move to the limit of the rightward movement trajectory of the reciprocating screw and begin to turn to the left. The threaded sleeve and the elliptical ring frame move to the left, which will pull out the left pusher frame. After the pusher frame is pulled out, the front toothed part will mesh with the half gear to synchronously drive the slide plate, positioning frame and coil assembly to continue to descend at equal distances, leaving stacking space for the next right E-layer. S2, Stacking Stop: When the pusher pushes the E stack in the storage box to stack towards the coil assembly, the pushed E stack will enter the corresponding guide slot for limiting and guiding. As the E stack continues to move, the E stack will press the inclined surface of the inclined block until the E stack passes the inclined block. After the corresponding inclined block loses its pressing force, it will reset and fit the flat surface with the E stack to prevent reverse movement. S3, Stacking and Compacting: When the pusher pushes the E stacks to be stacked crosswise, the E stacks will be squeezed against the inclined plate, causing the inclined plate to rise and leaving the stacking space for the E stacks.

[0013] Beneficial effects This invention provides a core lamination device and its method of use. Compared with existing technologies, it has the following advantages: (1) The iron core lamination device and its usage method, by setting a cross-stacking mechanism, a stop mechanism and a compaction mechanism on the top of the base, enable the device to automatically cross-stacking the laminations layer by layer through the above-mentioned cooperation, thereby improving the stacking efficiency, and simultaneously stopping the stacking position of the laminations to avoid irregular stacking, and simultaneously continuously compacting the stacked laminations to prevent the laminations from collapsing.

[0014] (2) The iron core lamination device and its usage method, by setting a limiting sleeve, a limiting rod, a first reset spring, a ring cover and a slot between the inner threaded cylinder and the base, can enable the intermittent rotation of the inner threaded cylinder to be assisted in positioning the rotation direction of the inner threaded cylinder through the above-mentioned cooperation.
