Method of crimping terminal and apparatus for the same

摘要

A terminal barrel is crimped to a wire laid on an anvil. In the crimping operation, a servo-motor drives a driving axis, the forward and reverse rotation of which vertically reciprocates a crimper. The operation includes the steps of: preliminary recording reference speeds or accelerations of the crimper at vertical positions in the reciprocating movement, and the reference value of a current which is supplied to the servo-motor when the terminal is crimped; descending the crimper at the reference speeds corresponding to the crimper position while the crimper descends from its top position to its crimping start position; crimping the terminal by supplying the reference current to the servo-motor during a predetermined period while the crimper is crimping the terminal.
