Abstract

A conductor shaping apparatus with first and second shaping dies that are movable toward and away from each other along a first direction, and that are moved toward each other to shape the at least one first bent portion and the at least one second bent portion, wherein one of the first and second shaping dies is configured to be moved away from the other along a second direction that is different from the first direction such that the conductor is not dragged when the first and second shaping dies are moved away from each other along the first direction after shaping of the first and second bent portions is completed.

First claim

1 - 14 . (canceled)

15 . A conductor shaping apparatus that shapes at least one first bent portion and at least one second bent portion in which a conductor is bent in a first bend direction and a second bend direction that is orthogonal to the first bend direction, respectively, the conductor shaping apparatus comprising
first and second shaping dies that are movable toward and away from each other along a first direction, and that are moved toward each other to shape the at least one first bent portion and the at least one second bent portion, wherein one of the first and second shaping dies is configured to be moved away from the other along a second direction that is different from the first direction such that the conductor is not dragged when the first and second shaping dies are moved away from each other along the first direction after shaping of the first and second bent portions is completed.

16 . The conductor shaping apparatus according to claim 15 , wherein
the first direction is parallel to a direction of a load for shaping one of the first and second bent portions, and the second direction is parallel to a direction of a load for shaping the other of the first and second bent portions and orthogonal to the first direction.

17 . The conductor shaping apparatus according to claim 15 , wherein
one of the first and second shaping dies is configured to be moved away from the other of the first and second shaping dies along the second direction at the same time as the one of the first and second shaping dies is moved away from the other of the first and second shaping dies along the first direction after shaping of the first and second bent portions is completed.

18 . The conductor shaping apparatus according to claim 16 , wherein
one of the first and second shaping dies is configured to be moved away from the other of the first and second shaping dies along the second direction at the same time as the one of the first and second shaping dies is moved away from the other of the first and second shaping dies along the first direction after shaping of the first and second bent portions is completed.

19 . The conductor shaping apparatus according to claim 15 , wherein
one of the first and second shaping dies is configured to be moved away from the other of the first and second shaping dies along the second direction before the one of the first and second shaping dies is moved away from the other of the first and second shaping dies along the first direction after shaping of the first and second bent portions is completed.

20 . The conductor shaping apparatus according to claim 16 , wherein
one of the first and second shaping dies is configured to be moved away from the other of the first and second shaping dies along the second direction before the one of the first and second shaping dies is moved away from the other of the first and second shaping dies along the first direction after shaping of the first and second bent portions is completed.

21 . The conductor shaping apparatus according to claim 15 , wherein
one of the first and second shaping dies is a movable die that is advanceable and retractable along the first direction, and the other of the first and second shaping dies is a fixed die.

22 . The conductor shaping apparatus according to claim 16 , wherein
one of the first and second shaping dies is a movable die that is advanceable and retractable along the first direction, and the other of the first and second shaping dies is a fixed die.

23 . The conductor shaping apparatus according to claim 17 , wherein
one of the first and second shaping dies is a movable die that is advanceable and retractable along the first direction, and the other of the first and second shaping dies is a fixed die.

24 . The conductor shaping apparatus according to claim 19 , wherein
one of the first and second shaping dies is a movable die that is advanceable and retractable along the first direction, and the other of the first and second shaping dies is a fixed die.

25 . The conductor shaping apparatus according to claim 21 , further comprising:
a movable stage that is advanceable and retractable along the first direction, and that supports the movable die such that the movable die is turnable about a support shaft that extends in a direction that is orthogonal to both the first and second directions; and an urger disposed between the movable die and the movable stage to urge the movable die away from the fixed die along the second direction, wherein the movable die abuts against the conductor on a side proximate to the fixed die, in the second direction, with respect to a plane that includes an axis of the support shaft and that extends in the first direction as the movable die approaches the fixed die along the first direction.

26 . The conductor shaping apparatus according to claim 25 , wherein
a stroke of movement of the movable die with respect to the fixed die along the second direction is smaller than a thickness of the conductor in the second direction.

27 . The conductor shaping apparatus according to claim 25 , further comprising
a guide that guides the movable die such that the movable die directly faces the fixed die.

28 . The conductor shaping apparatus according to claim 21 , further comprising:
a movable stage that is advanceable and retractable along the first direction, and that supports the movable die such that the movable die is movable in the second direction; an urger disposed between the movable die and the movable stage to urge the movable die away from the fixed die along the second direction; and a guide that is advanceable and retractable along the first direction, and that guides the movable die such that the movable die approaches the fixed die along the second direction against an urging force of the urger as the movable stage approaches the fixed die along the first direction.

29 . The conductor shaping apparatus according to claim 28 , wherein:
the guide includes a roller that is rotatable about an axis that extends in a direction that is orthogonal to both the first and second directions; and the movable die abuts against the roller on a side proximate to the fixed die, in the second direction, with respect to a plane that includes an axis of the roller and that extends in the first direction as the movable die approaches the fixed die along the first direction.

30 . The conductor shaping apparatus according to claim 15 , further comprising
a third shaping die that is movable toward and away from one of the first and second shaping dies along the first direction, and that is capable of cooperating with one of the first and second shaping dies to shape the first bent portion that is the closest to a free end side of the conductor, wherein the third shaping die is configured to be movable toward and away from one of the first and second shaping dies along the second direction.

31 . The conductor shaping apparatus according to claim 15 , wherein
the conductor has a rectangular cross section, the first bend direction is an edgewise direction that is orthogonal to a short side of the cross section of the conductor, the second bend direction is a flatwise direction that is orthogonal to a long side of the cross section of the conductor, the first bent portion is an edgewise bent portion that is bent in the edgewise direction, and the second bent portion is a flatwise bent portion that is bent in the flatwise direction.
