Abstract

PURPOSE:To simplify manufacturing steps and to reduce a cost by engaging a clinch shape in clinch joint, and shaping a spigot for attaching an observation window and a bracket to both ends of a steel plate frame simultaneously upon rolling. CONSTITUTION:Clinch shapes 9A, 9B in which OMEGA-shaped protrusions and inverted OMEGA-shaped protrusions are alternately disposed are punched by a press at both ends of the short side of a longitudinal steel plate developed in coincidence with the finishing size of a frame 4. A punch roller 11 is attached to a rolling machine in coincidence with the outer diameter d1 of the attachment of a bearing bracket and the outer diameter d2 of a stator core, the pre-worked steel is plate rounded by rolling, the shapes 9A, 9B are simultaneously engaged, and the cylindrical frame 4 is formed. Since an observation window and a spigot can be simultaneously formed by one step of rolling, the steps can be simplified and its cost can be reduced.
