Method for locating and overlapping center of transformer core

Abstract

The invention relates to a production technology of a transformer iron core, in particular to a central positioning and stacking method of the transformer iron core. In accordance with the technical proposal, the central positioning and stacking method of the transformer iron core comprises upper and lower yokes which are positioned at upper and lower ends of the iron core, side columns which arepositioned at left and right sides of the iron core and middle columns which are positioned in the middle part of the iron core, wherein, the side columns are parallel to the middle columns; the central positioning and stacking method is characterized in that the method comprises the following steps: step 1, positioning: the positions of the middle columns, the side columns and the upper and the lower yokes are firstly positioned on a positioning support; step 2, stacking of the middle columns: a plurality of pieces of the middle columns are sequentially stacked on the positioning support; step 3, insertion: a plurality of pieces of the middle columns are all well stacked, then the stacking of the upper and the lower yokes and the side columns is started, when in stacking of the upper andthe lower yokes and the side columns, the upper and the lower yokes and the side columns are stacked on the positioning support piece-by-piece according to the sequence of firstly stacking one piece of the upper and the lower yokes and then stacking one piece of the side column. The central positioning and stacking method can facilitate the packaging of the iron core and the insertion after the packaging.

Description

technical field [0001] The invention relates to a production technology of a transformer iron core, in particular to a central positioning and stacking method of a transformer iron core. Background technique [0002] The original lamination method is the flat lamination method, and the specific process is as follows: the iron core is formed by laminating cold-rolled grain-oriented silicon steel sheets with a thickness of 0.23-0.35mm. Its basic sheet shape generally has the following three types: 1. Center column; 2. Upper and lower yokes. The upper yoke 2 is located at the upper end of the transformer core, and the lower yoke 2 is located at the lower end of the transformer core. Generally, the upper yoke and the lower yoke The sheet type is the same, and a gap matching the sharp corner 10 on the center column 1 is provided on the upper yoke and the lower yoke; 3. The side column, the side column 3 includes a side column located on the left side of the transformer core and a...
