Abstract

The stacked core assembly apparatus, which can perform assembly at a high speed while keeping strength of an angle indexing apparatus, comprises a press machine 1, a non-synchronous transmitting apparatus 10 and an angle indexing apparatus 7. The non-synchronous transmitting apparatus 10 transforms a constant revolution of the press machine 1 into a variable revolution. The angle indexing apparatus 7 is connected to the non-synchronous transmitting apparatus 10 via a coupling device 20, and is connected to a rotatably stacking cavity device 51 of a press die 5. An accelerated rotational speed period of an output shaft 13 of the non-synchronous transmitting apparatus 10 is set during a Feeding-Phase period of time of the press machine 1, and thereby, a rotational state completion of a driving shaft 33 of the angle indexing apparatus 7 completes earlier than the Feeding-Phase period of time completion of the press machined 1 so that a non-rotating period of time can be provided.

Claims (3)

1. A stacked core assembly apparatus, which comprises a press machine, a feeder for feeding a thin-strip material into the press machine, and an indexing apparatus outputting an intermittent rotation when driven from the press machine is transmitted thereto, and a stacking member or stacked core is formed in an intermittent rotational stacking cavity device, whereas driven by the angle indexing apparatus intermittently and the angle indexing device is driven by a constant rotational speed of a driving unit of the press machine, characterized in that,

the angle indexing apparatus is connected to the driving unit of the press machine via a non-synchronous transmitting mechanism, and an output shaft of the non-synchronous transmitting mechanism has a variable rotating speed period of time with respect to an input shaft of the non-synchronous transmitting mechanism, and thereby, a non-rotating state period of time is provided after a rotating state period of time completion and before a feeding phase period of time completion, within the a predetermined Feeding-Phase period of time range.

2. The stacked core assembly apparatus according to claim 1 , wherein the input and output shafts of the non-synchronous transmitting mechanism are arranged in an eccentric position, and are connected by a connecting levers, which is rotatably supported by pins eccentrically positioned with respect to each of rotational axis of the input shaft and that of the output shaft.
