Abstract
This adhesively-laminated core manufacturing method is a method for manufacturing an adhesively-laminated core by punching a plurality of steel sheet parts while a strip-shaped steel sheet is fed and laminating the steel sheet parts via an adhesive, and includes a step of forming a curing acceleration portion by applying and drying a curing accelerator on one or both surfaces of the strip-shaped steel sheet before a pressing oil is applied, and a step of applying the pressing oil to a surface of the curing acceleration portion.
Claims17
An adhesively-laminated core manufacturing method which is a method for manufacturing an adhesively-laminated core by punching a plurality of steel sheet parts while a strip-shaped steel sheet is fed and laminating the steel sheet parts via an adhesive, the adhesively-laminated core manufacturing method comprising:
- a step of forming a curing acceleration portion by applying and drying a curing accelerator on one or both surfaces of the strip-shaped steel sheet before a pressing oil is applied;
- and
- a step of applying the pressing oil to a surface of the curing acceleration portion.
An adhesively-laminated core manufacturing device which is a device for manufacturing an adhesively-laminated core by laminating a plurality of steel sheet parts punched out of a strip-shaped steel sheet via an adhesive while feeding the strip-shaped steel sheet, the adhesively-laminated core manufacturing device comprising:
- a curing acceleration portion forming part forming a curing acceleration portion by applying and drying a curing accelerator on one or both surfaces of the strip-shaped steel sheet;
- a pressing oil application part disposed downstream of the curing acceleration portion forming part and configured to apply a pressing oil to at least a surface of the curing acceleration portion;
- a pressing part disposed downstream of the pressing oil application part and configured to apply press processing to the strip-shaped steel sheet;
- and
- an adhesive application part applying the adhesive to the one surface of the strip-shaped steel sheet.
