Wind driven generator stator iron core lamination forming tool and a lamination forming method

Abstract

The invention discloses a wind driven generator stator iron core lamination forming tool and a lamination forming method, and solves the problem that an integral silicon steel sheet iron core is difficult to separate from an integral positioning support cylinder in an existing stator iron core lamination tool. An integral positioning support cylinder of a laminated silicon steel sheet iron core isdecomposed into four arc-shaped laminated positioning support plates, a spacing gap is formed between every two adjacent arc-shaped laminated positioning supporting plates, and after stator iron coresilicon steel sheets are laminated, the fixing mechanisms of the arc-shaped laminated positioning supporting plates are dismounted, so that the four arc-shaped laminated positioning supporting platesare in a movable state, and the laminated stator iron core can be conveniently separated from the stator iron core; and the silicon steel sheet excircle positioning vertical plate (13) is matched with a silicon steel sheet laminated excircle positioning groove (21) formed in the excircle of the stator core silicon steel sheet (12), so that the positioning rib embedding grooves in the laminated silicon steel sheets are aligned. The quality of the iron core is improved, and the scratching probability of the inner side wall of the iron core is reduced.

Description

Technical field [0001] The invention relates to a stator iron core lamination forming tool, in particular to a wind generator stator iron core lamination forming tool and a lamination forming method. Background technique [0002] The traditional wind turbine stator iron core is completed on the iron core stacking tooling. The iron core stacking tooling is composed of the stacking tooling base and the integral positioning support cylinder on it; when stacking, the silicon steel sheet Sleeve on the overall positioning support cylinder in turn, and after stacking to a specified height, place a pressure plate and a pressure sleeve on the top silicon steel sheet, press the laminated iron core through the press, and press the outer surface of the iron core The reinforcing ribs on the upper part are embedded in the reserved silicon steel sheet reinforcing ribs embedded in the groove and then welded. The reinforcing ribs connect the laminated silicon steel sheets into a whole. After the ...
