Problems solved by technology

However, the surface of the crimper 101 on which the crimping piece portion 107 collides is prone to wear during the pressing and fixing (extrusion deformation) operation, and it is difficult to maintain a good surface state for a long time
Also, when stable crimping cannot be achieved due to wear of the crimper 101, there is a concern that mechanical properties or electrical properties may be adversely affected

Abstract

A crimping device comprising an anvil for supporting a metal terminal including a base plate portion for mounting an electric wire thereon, and a pair of crimping crimps respectively extending upward from opposite sides of the base plate portion. a tab part; and a crimping device, the crimping device has a pressing and fixing part for pressing and fixing the crimping piece part. The anvil cooperates with the pressing and fixing part of the crimper to press and fix the crimping piece part, which is used for crimping the crimping piece part to the electric wire installed on the metal terminal. Mirror-finishing is performed on the press-fixed portion.

Description

technical field [0001] The present invention relates to a crimping apparatus for crimping a metal terminal (having a pair of crimping piece portions respectively extending upward from opposite sides of a substrate portion thereof) to an electric wire. Background technique [0002] There is known a conventional crimping apparatus in which an arc-shaped portion 103 with a radius R1 and an arc-shaped portion 104 with a radius R2 are formed on an upper toothed die 102 of a crimper 101, and as shown in FIG. 9 As shown, a pair of crimping piece parts 107 of the metal terminal 106 which are respectively provided on the right and left sides of the imaginary straight line A passing through the apex and on which the electric wire 105 is placed are formed by the crimping tool 101 and the anvil. The seat 108 is deformed by extrusion (ie, press-fitted to the electric wire 105) (see, for example, JP-UM-A-61-48681). [0003] In JP-UM-A61-48681, the crimper 101 is shaped to improve perform...
