TERMINAL CRIMPING APPARATUS
First Claim
1. A terminal crimping apparatus comprising:
- a lower die on which a bottom plate of a conductor crimping portion of a terminal is placed, the conductor crimping portion being made up of the bottom plate and a pair of left and right crimping pieces which rise from side edges of the bottom plate which face each other in a transverse direction; and
an upper die which is disposed above the lower die so as to press the crimping pieces of the conductor crimping portion between the lower die and itself and which has two arch-shaped crimping portions each made up of an arc-like surface and formed at a portion thereof which faces the lower die so as to bend inwards the pair of left and right crimping pieces, whereinthe bottom plate of the conductor crimping portion of the terminal is placed on the lower die, a distal end portion of a conductor of an electric wire is placed on the bottom plate, and in this state, the upper die is relatively pressed towards the lower die so as to round inwards the pair of left and right crimping pieces so that the crimping pieces are pressure connected to the conductor of the electric wire, the terminal crimping apparatus further comprising;
a detection device configured to detect a transversely unbalanced load applied to the upper and lower dies in a crimping process in which the upper die is relatively pressed towards the lower die so that the pair of left and right crimping pieces are crimped for pressure connection to the conductor of the electric wire.

Abstract
There is provided a terminal crimping apparatus which can detect a crimping failure mode which produces a transversely asymmetrical crimped shape in a crimped product. The terminal crimping apparatus includes an anvil (102A) which is a lower die on which a conductor crimping portion (11) of a terminal (10) is place and a crimper (101A) which is an upper die which bends inwards a pair of left and right crimping pieces (11L, 11R) of the conductor crimping portion (11), and the terminal crimping apparatus further includes a detection device which detects a transversely unbalanced load in the upper and lower dies (101A, 101B) in a crimping process in which the upper die (101A) is pressed down towards the lower die (102A) so as to crimp the pair of left and right crimping pieces (11L, 11R) on to a conductor (Wa) of an electric wire so as to crimp the conductor (Wa).

4. A terminal crimping apparatus comprising:
-
a lower die on which a bottom plate of a conductor crimping portion of a terminal is placed, the conductor crimping portion being made up of the bottom plate and a pair of left and right crimping pieces which rise from side edges of the bottom plate which face each other in a transverse direction; and an upper die which is disposed above the lower die so as to press the crimping pieces of the conductor crimping portion between the lower die and itself and which has two arch-shaped crimping portions each made up of an arc-like surface and formed at a portion thereof which faces the lower die so as to bend inwards the pair of left and right crimping pieces, wherein the bottom plate of the conductor crimping portion of the terminal is placed on the lower die, a distal end portion of a conductor of an electric wire is placed on the bottom plate, and in this state, the upper die is relatively pressed towards the lower die so as to round inwards the pair of left and right crimping pieces so that the crimping pieces are pressure connected to the conductor of the electric wire, the terminal crimping apparatus further comprising; a detection device configured to detect a vertically unbalanced distortion in at least two locations on the lower die which are spaced apart in a transverse direction in a crimping process in which the upper die is relatively pressed towards the lower die so that the pair of left and right crimping pieces are crimped for pressure connection to the conductor of the electric wire. - View Dependent Claims (5, 6)
