Abstract

The invention provides a tool for bending an electrostatic ring lead of a transformer, belonging to technical field of transformer manufacture and comprising a contact roller, a support, a rotation disc, and a hold-down mechanism used for regulating the radial clearance between the contact roller and the rotation disc, wherein the rotation disc and the hold-down mechanism are respectively arrangedon the support, the contact roller is connected to the hold-down mechanism; the outside circumferential surface of the rotation disc is provided with a circumferential slot; the width of the circumferential slot adapts to the thickness of the electrostatic ring lead of the transformer; the contact roller is arranged outside the outside circumferential surface of the rotation disc; and the axial line of the contact roller is parallel to the axial line of the rotation disc. The invention changes manual manufacture into tool manufacture, thereby creating a brand-new method for producing an electrostatic ring, improving work efficiency reducing the technical content of operation, and being is easy to learn and operate; the appearance of a bent forming copper bus is smooth and attractive, andthe dimension precision is easy to guarantee; the appearance of the bent forming copper bus has no scratches or sharp angles, and the electric property is higher. The tool has small volume and can beflexibly moved.

Description

technical field [0001] The invention relates to a bending tool for a static ring wire of a transformer, which belongs to the technical field of transformer manufacturing. Background technique [0002] The traditional transformer electrostatic ring wire Weibang is made by hand. The copper busbar is beaten with wood or iron on the platform, so that the copper busbar is plastically deformed and bent, and then wrapped with the skeleton after plastic deformation. Manual production is labor-intensive, time-consuming, inefficient, and the radius of curvature cannot be guaranteed. It requires high skills for operators. At the same time, it is easy to damage the copper busbar itself by continuously beating the copper busbar during the production process, causing sharp corners or surface scratches. Electrostatic ring discharge breakdown. Secondly, the copper bus bar is plastically deformed when it is knocked. The copper bus bar deforms in the thickness direction, and the surface is up...
