Embodiment Construction

[0032] The specific content of the present invention is illustrated by taking the three-phase three-column polygonal cross-section open-type three-dimensional wound iron core as an example.

[0033] One of the present inventions, an opening cutting tool for coiled iron core

[0034] The opening cutting tool of the present invention is suitable for layered and interlaced cutting of silicon steel strips when the iron core single frame 13 has been wound into a closed single frame and there is only a small gap between the cut yoke silicon steel sheets 131 .

[0035] like image 3 As shown, the opening cutting tool includes an upper beam 1 , an insert piece 2 , a slider 4 , a circular hob 5 , and a bar knife 3 .

[0036] The upper beam 1 and the insertion piece 2 are connected and fixed at one end to form a fork-shaped structure with one end open. The cross-section of the insertion piece 2 is flat to facilitate insertion into the narrow gap between the layers of the silicon steel ...

Abstract

The present invention relates to opening cutter for rolled transformer iron core and its cutting process. The opening cutter includes an upper cross beam, an inserted sheet, a sliding block, a circular hob, a cutting bar and a clamping hook mechanism. The upper cross beam has one end connected to the inserted sheet to form one fork structure with one opened end, the cutting bar is fixed to the upper part of the inserted sheet, the sliding block is installed onto the upper cross beam and can slide along the upper cross beam, the circular hob on the sliding block can rotate freely, and when the sliding block shifts, the edge of the circular hob contacts with the edge of the cutting bar to produce roll shearing. By means of the technological scheme of the present invention, it is possible to make various kinds of rolled iron core with planar opening or stereo opening.

Description

technical field [0001] The invention relates to a manufacturing technology of a coiled iron core of a transformer, in particular to an opening cutting tool for a coiled iron core and a cutting method thereof. Background technique [0002] At present, the coiled cores used in transformers are all closed coiled cores. Compared with laminated cores, closed coiled cores have obvious advantages: good performance, small no-load loss, small no-load current, and low noise. But there are also obvious disadvantages, such as winding with an iron core, so winding is difficult. Especially for large and medium-sized transformers, due to the large size of the wire gauge, the large number, and the complicated structure of the wire package during winding, it is impossible to use winding with iron core. Especially for dry-type transformers whose wire packages need to be insulated separately, it is impossible to use wound iron cores. Therefore, the closed wound iron core with excellent perfo...
