The production line according to the present invention is provided with a pressurization measurement apparatus adjacent to a press-working apparatus, a temporary laminate assembly worked and laminated by a press in the press-working apparatus is sent to the pressurization measurement apparatus, and a laminate assembly is produced by being pressurized and being subjected to regular caulking by a hydraulic servo press of the pressurization measurement apparatus. At this time, the lamination height of a regularly caulked laminate assembly is measured by a linear scale secured at the pressurization measurement apparatus. The main controller of a control apparatus inputs data of the measured lamination height, and adds and subtracts the set number of thin plates to be laminated of a laminate assembly by controlling the laminating means of the press-working apparatus so that the measurement lamination height is matched to the set lamination height using the measured lamination height, the preset lamination height, the height dimension tolerance, and the tolerance for judging the number of thin plates.

Method and production line for laminate assembly

The stacked core assembly apparatus, which can perform assembly at a high speed while keeping strength of an angle indexing apparatus, comprises a press machinea non-synchronous transmitting apparatusand an angle indexing apparatusThe non-synchronous transmitting apparatustransforms a constant revolution of the press machineinto a variable revolution. The angle indexing apparatusis connected to the non-synchronous transmitting apparatusvia a coupling deviceand is connected to a rotatably stacking cavity deviceof a press dieAn accelerated rotational speed period of an output shaftof the non-synchronous transmitting apparatusis set during a Feeding-Phase period of time of the press machineand thereby, a rotational state completion of a driving shaftof the angle indexing apparatuscompletes earlier than the Feeding-Phase period of time completion of the press machinedso that a non-rotating period of time can be provided.
