    Abstract: There are provided a cold pressure welding apparatus and a coil manufacturing apparatus capable of successfully cold pressure welding even rectangular conductors and improving the stability of their connected portions as well as a rectangular conductor coil, capable of improving its space factor and its heat dissipation performance and causing no characteristic deterioration due to cutting and welding, and a method of manufacturing such a coil.
    The cold pressure welding apparatus includes: a first holding part capable of sandwiching a first flat conductor; a second holding part disposed opposite to the first holding part and capable of sandwiching a second flat conductor; and a drive part for moving the first holding part and the second holding part. The drive part can move the first holding part and the second holding part between a first direction separated position and a close position along a first direction. The drive part can move the first holding part and the second holding part between a second direction separated position and a sandwiching position along a second direction. In a sandwiching state, the drive part moves the first holding part and the second holding part to the sandwiching position, so that the first holding part sandwiches the first flat conductor and the second holding part sandwiches the second flat conductor. In a pressure welding state, the drive part moves the first holding part and the second holding part in the sandwiching state from the first direction separated position to a direction toward the close position, so that an end face of the first flat conductor and an end face of the second flat conductor are butted and pressed against each other, and thus welded together. In a retracted state, the drive part moves the first holding part and the second holding part to the first direction separated position and to the second direction separated position.

    Abstract translation: 提供了一种冷压焊接装置和线圈制造装置，其能够成功地对矩形导体进行冷压焊，并提高其连接部分的稳定性以及矩形导体线圈，能够提高其空间因子及其散热性能， 不会导致由于切割和焊接引起的特性劣化，也不会产生这种线圈的制造方法。 冷压焊设备包括：能够夹住第一扁平导体的第一保持部件; 第二保持部，其与所述第一保持部相对设置并且能够夹持第二扁平导体; 以及用于使第一保持部和第二保持部移动的驱动部。 驱动部可以沿着第一方向在第一方向分离位置和关闭位置之间移动第一保持部和第二保持部。 驱动部能够沿第二方向在第二方向分离位置和夹持位置之间移动第一保持部和第二保持部。 在夹持状态下，驱动部将第一保持部和第二保持部移动到夹持位置，使得第一保持部夹持第一扁平导体，并且第二保持部夹持第二扁平导体。 在压力焊接状态下，驱动部将第一保持部和夹持状态的第二保持部从第一方向分离位置移动到朝向闭合位置的方向，使得第一扁平导体的端面和端部 第二扁平导体的表面彼此对接并压靠，从而焊接在一起。 在缩回状态下，驱动部将第一保持部和第二保持部移动到第一方向分离位置和第二方向分离位置。
