摘要： PROBLEM TO BE SOLVED: To provide a stator core-manufacturing method capable of preventing a connection part of an annular core sheet from being recovered from a curved state in such a manner that a slit is opened by spring-back.SOLUTION: In a curving step, connection parts 52 are curved around curving centers 75 located on the notch 63 sides relative to the connection parts 52, respectively. Thus, when forming an annular core sheet by curving the connection parts 52 of a band-like core sheet, the connection parts 52 are pulled circumferentially in a full width direction. Therefore, when a restriction of the annular core sheet is canceled after the connection parts 52 are curved, the connection parts 52 are recovered from a deformed state so as to be contracted in the circumferential direction by spring-back. The recovery at such a time acts to close slits 56. Therefore, the connection parts 52 of the annular core sheet can be prevented from being recovered from a curved state by opening the slit 56 by spring-back.
摘要翻译：要解决的问题：提供一种定子芯制造方法，其能够防止环形芯片的连接部分从弯曲状态恢复，使得通过回弹打开狭缝。解决方案：在弯曲连接部分52相对于连接部分52分别围绕位于凹口63侧的弯曲中心75弯曲。因此，当通过弯曲带状芯片的连接部分52形成环形芯片时，连接部分52在全宽方向上沿周向拉伸。因此，在连接部52弯曲之后，当环形芯片的限制被消除时，连接部52从变形状态恢复，从而通过回弹在圆周方向上收缩。此时的恢复作用成闭合狭缝56.因此，通过回弹打开狭缝56，可以防止环形芯片的连接部52从弯曲状态恢复。

摘要： PROBLEM TO BE SOLVED: To provide a method of manufacturing a stator for an electric rotating machine, capable of preventing positional deviations or the like of windings due to spring back in forming a stator winding. SOLUTION: This method is intended for use in manufacturing the stator for the electric rotating machine 1 having: the stator winding 40 with a wound body formed by spirally assembling rolled planar electric wires each having in-slot portions 51 and turn portions 52, the wound body being formed by being wound one or more turns, so that the plurality of turn portions run along the circumferential direction; and a stator core 30. The manufacturing method includes a winding forming step for forming the wound body so that the turn portions 52 can have a predetermined curvature in expectation of the deformation after the formation. A ratio of a curvature in the winding forming step to a curvature after assembling the stator winding 40 on the stator core 30 is larger in the outermost turn part 52A than in the innermost turn part 52K.

摘要： PROBLEM TO BE SOLVED: To provide a method of manufacturing a coil assembly unit for rotary electric machines, which causes less deformation to the coils and which allows a smaller-size device to weave coil wires at higher speed. SOLUTION: In this manufacturing method, the coil forming step, the coil weaving step, and the coil compressing step are performed sequentially. In the coil forming step, the bent portions are formed at both ends of each of slot housing portions of coil wires so that the mutually adjacent linear portions are deviated from each other. Thanks to this deviation of mutually adjacent linear portions, in the weaving step, both turn portions of the pair of formed coil wires can be weaved sequentially with each other without mutual interference when at least one of the formed coil wires is rotated or revolved in the coil weaving step. In the compressing step, the woven coil assembly is compressed by compressing the woven coil so that each bent portion is deformed to be linear to allow the mutually adjacent linear portions to come closer to each other.

摘要翻译：要解决的问题：提供一种制造用于旋转电机的线圈组件单元的方法，其使线圈变形较小，并且允许较小尺寸的装置以更高的速度编织线圈线。解决方案：在该制造方法中，顺序地进行线圈形成步骤，线圈编织步骤和线圈压缩步骤。在线圈形成步骤中，弯曲部分形成在线圈线的每个槽容纳部分的两端，使得相互相邻的直线部分彼此偏离。由于相互相邻的直线部分的这种偏差，在织造步骤中，当成形的线圈线中的至少一个在所形成的线圈线中的至少一个旋转或旋转时，一对成形的线圈线的两个转向部分可以相互编织而不相互干涉线圈编织步骤。在压缩步骤中，通过压缩编织线圈来压缩编织线圈组件，使得每个弯曲部分变形为线性的，以允许相互相邻的线性部分彼此靠近。版权所有（C）2010，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a coil end molding method of a stator coil that can suppress the bulge of the coil in the molding by bending a coil end.
SOLUTION: The method has a right-angle bending step in which part of an insulated coated conductor 30 that falls on a coil end is bent at right angle. In this right-angle bending step, using a die 52 having a guide groove 52d of almost the same width with that of the conductor 30, the conductor 30 is bent at right angle by moving a punch 54 relatively to the die 52 side with the conductor 30 fitted into the guide groove 52d of the die 52. Thus, both sides of the conductor 30 contact the sidewalls of the guide groove 52d of the die 52, so that a force of both sides of the conductor 30 tending to bulge is suppressed by the sidewalls of the guide groove 52d of the die 52 and thereby the bulge can be suppressed.

摘要： PROBLEM TO BE SOLVED: To provide a method of molding the coil end of a stator core, where the rubbing or pulling of an insulating cover is reduce, when molding of a step-form coil end. SOLUTION: A receiving mold set 100 and a pushing mold set 200 are made to face each other across a lead wire 10 covered with an insulator. Individual receiving molds (lower molds) 101-104 of the receiving mold set 100 separately face individual pushing molds (upper molds) 201-204 of the pushing mold set 200. First, the longitudinal center of the coil end slated section of the lead wire 10, covered with an insulator, is pushed and bent downward, being caught with the receiving mold 101 and the pushing mold 201. Hereafter, the coil end slated section is pushed and bent in order toward the longitudinal peripheral side. By doing it this way, other lead wire 10 covered with an insulator can freely follow it, when a specified region of the coil end slated section is caught with a single pushing mold and single receiving mold and it is shifted downward; and thus, it becomes possible to prevent the drop of the withstand voltage due to rubbing or pulling of the insulating cover.

摘要： PROBLEM TO BE SOLVED: To enable shaping in desired finishing dimensions even if a shape has a lot of bendings or a thermoplastic resin before crystallization is used for shaping.
SOLUTION: In a method and apparatus for shaping a coil end of a stator coil to bend a scheduled part of a coil end of an insulation-coated conductor with a rectangular wire coated with an insulator by the press die for shaping the scheduled part of the coil end of the stator coil into a predetermined shape, the blade parts (concave forming die 15a and convex forming die 20a) of the press die (die 15 and punch 20) are structured so that a gap between the blade parts of the press die in pressing is formed to be different from a gap W1 at the linear part B1 corresponding to the linear part at the scheduled part (coil end) of the coil end and a gap W2 at the nonlinear part B2 corresponding to the nonlinear part at the scheduled part of the coil end. This structure can have a desired shape of finishing dimensions (in an allowable area) even if the expansion/contraction degree of the insulator at the linear section differs from that at the nonlinear section in pressing.
