Lead forming and bending mechanism

摘要

Four lead bending devices (40) are arranged so that they surround a shaping tool (31). A rotary arm (41) extends from wire support (43), at each device, with an arm guide underneath holding the rotary arm to prevent its deflection. The wire support is coupled to a drive unit (44). The arm rotation provides bending of the lead (1) end sections, with a third angle and a fourth angle such that the support face can get near the shaping punch (33) during its contact with the end sections. For the third angle, a flat housing body with the leads is fitted to the shaping tool, after the pre-bending step.
