Paper-clad copper flat wire bending tool

Abstract

The invention discloses a paper-covered copper strap wire bending tool, relates to the technical field of transformer repair and maintenance. The paper-covered copper strap wire bending tool is simplein structure and can be prevented from twisting when being bended. The paper-covered copper strap wire bending tool comprises a mother board and a cover board; the positive surface of the mother board is provided with a wire groove; the wire groove comprises a first transverse groove, a second transverse groove and a slanting groove; the slanting groove is arranged at the middle part of the mother board; the first transverse groove and the second transverse groove are arranged in the length direction of the mother board, are arranged on edges of the two sides of the mother board respectivelyand extend to the slanting groove from the two ends of the mother board respectively; the cover board is attached to the positive surface of the mother board and covers the wire groove; the cover plate is hinged to the mother board and is detachably connected with the mother board; and after the cover plate is rotated, the wire groove can be exposed. By adopting the paper-covered copper strap wirebending tool provided by the invention, a paper-covered copper strap wire is put in the wire groove, the mother board and the cover board press the paper-covered copper strap wire from the two sidesto ensure that the paper-covered copper strap wire cannot twist in a thickness direction, so that the paper-covered copper strap wire is prevented from twisting when being bended.

Description

technical field [0001] The invention relates to the technical field of transformer repair and maintenance, in particular to a paper-wrapped copper flat wire bending tool. Background technique [0002] During the winding process of the transformer coil, it is necessary to bend the paper-wrapped copper flat wire, and bend the paper-wrapped copper flat wire along the width direction into a figure 1 shape shown. Wide flat paper-clad copper flat wire refers to a paper-clad copper flat wire with a larger width to thickness ratio. The wide and flat paper-clad copper flat wire is too large in the width direction and the thickness direction, resulting in a large difference in its mechanical strength. During the bending process along the width direction, the paper-clad copper flat wire is easily deformed to the side with low mechanical strength. , that is, distortion occurs. During transformer maintenance, since there is no special bending equipment, it is difficult to bend wide an...
