Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wire winding frames, and specifically relates to a new type of amorphous alloy transformer wire winding frame. Background Art
[0002] The mold of the amorphous alloy dry-type transformer is formed by processing a 3mm thick whole cold-rolled steel plate into a straight surface part and an arc surface part. The arc surface needs to be processed on a plate rolling machine. Due to the small curvature radius of the arc surface, the special shape makes the mold processing very difficult. It often requires experienced workers to tap and correct it with a wooden mallet to be formed, and the size accuracy of the made mold is extremely poor and the error is large. Therefore, a new type of amorphous alloy transformer wire winding frame is needed. Summary of the Invention

The first positioning holes connect the arc wire winding part with the first contact surface, and the second positioning holes connect the arc wire winding part with the second contact surface. A number of groups of the first positioning holes and the second positioning holes fix the arc wire winding part in the recessed area.
[0006] Optionally, two clamping parts are symmetrically arranged on the middle side surface of the first wire winding part. The clamping parts are used to clamp the starting edge of the amorphous alloy for clamping the starting point of winding.
[0007] Optionally, an axis hole is provided through the center position of the first wire winding part. The axis hole is used to connect a rotating part to rotate the wire winding frame to wind the amorphous alloy.
[0008] Optionally, stabilizing parts are provided at the end face positions on both outer sides of the axis hole. A through hole adapted to the size and shape of the axis hole is provided at the center position of the stabilizing parts, so that an external rotating shaft is axially connected to the axis hole.

Detailed Embodiment
[0013] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a 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 those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0014] Please refer to Figure 1-2 , the present utility model provides a novel amorphous alloy transformer wire winding frame, including: a first wire winding part 1, a support member for the straight winding part of the amorphous alloy. The first wire winding part 1 is a cubic structure, and four concave areas are arranged at the four corners of the first wire winding part 1. The concave area has a first contact surface 2 and a second contact surface 3, and the first contact surface 2 is perpendicular to the second contact surface 3; two clamping parts 8 are symmetrically arranged on the middle side surface of the first wire winding part 1, and the clamping parts 8 are used to hold the starting edge of the amorphous alloy for clamping at the starting point of winding. An axis hole 9 is penetrated through the center position of the first wire winding part 1, and the axis hole 9 is used to connect a rotating member to rotate the wire winding frame to wind the amorphous alloy.
[0015] The first wire winding part 1 is made of 3mm cold-rolled steel plate.
[0016] The arc winding part 4 is installed in the recessed area 5 and is a support for the amorphous alloy arc winding part. A number of groups of first positioning holes 6 and second positioning holes 7 are provided on the arc winding part 4. The first positioning holes 6 and the second positioning holes 7 are arranged at different axial heights of the arc winding part 4, and the axial directions of the first positioning holes 6 and the second positioning holes 7 are perpendicular to each other. The first positioning holes 6 connect the arc winding part 4 with the first contact surface 2, and the second positioning holes 7 connect the arc winding part 4 with the second contact surface 2. A number of groups of the first positioning holes 6 and the second positioning holes 7 fix the arc winding part 4 in the recessed area.
[0017] It should be noted that the amorphous alloy is a long strip-shaped winding part. When winding the amorphous alloy, it is different from the general wire winding. Due to the wire material, when winding on a winding frame, it will not bulge or fold abnormally due to the arc at the corner. However, due to the structure of the amorphous alloy and the general winding requirements for the arc at the corner, that is, the mold of the arc winding part 4 has higher requirements. When producing the winding frame, since it is relatively inexpensive to use iron sheet to make the winding frame, it is not easy to make the accuracy of the arc part of the iron sheet mold. The arc winding part 4 uses a calibrated cylindrical steel pipe. The cylindrical steel pipe is installed inside the recessed area 5, and the diameter of the cylindrical steel pipe is adapted to the width of the first contact surface 2, so that the cylindrical steel pipe can form an arc-shaped support point inside the recessed area 5, enabling the amorphous alloy to achieve an arc shape during winding. Moreover, the calibrated cylindrical steel pipe has a low production cost and can be made using waste materials on site.
[0018] Stabilizers 10 are arranged at the end face positions on both outer sides of the axial center hole 9. A through hole adapted to the size and shape of the axial center hole 9 is arranged at the center position of the stabilizer 10, enabling an external rotating shaft to be axially connected with the axial center hole 9. Limiting members 11 are symmetrically arranged at both ends of the stabilizer 10. The height of the limiting members 11 is adapted to the height of the stabilizer 10, and the limiting members 11 are used to limit the rotation position of the winding frame.
[0019] It is worth noting that when using the winding frame, first insert the starting point of the amorphous alloy to be wound into the gap of the clamping part 8 to simply fix the amorphous alloy, and then insert the external rotating shaft into the axial center hole 9 to axially connect the axial center hole 9 with the rotating shaft. Drive the winding frame to rotate through the rotation of the rotating shaft, so as to transfer and wind the neatly arranged amorphous alloy onto the winding frame. This winding frame is used to make the inner core of a dry-type transformer.
[0020] As described above, these are only several embodiments of the present application and do not impose any form of limitation on the present application. Although the present application is disclosed above with preferred embodiments, it is not intended to limit the present application. Any person skilled in the art, without departing from the scope of the technical solution of the present application, making some changes or modifications using the disclosed technical content is equivalent to equivalent implementation cases and all fall within the scope of the technical solution.
