DISPOSITIVO DE ENHEBRADO AUTOMATICO PARA MAQUINA DE ELECTROEROSION POR HILO. |
摘要 |
An automatic wire threading device with a threading mechanism having a first free wheel and a second free wheel each having an inner traction surface and an outer traction surface. When a central processing unit (4) detects wire breakage, drives a pneumatic cylinder (25) against the action of a spring (22) that separates the free wheels so that pivoting arm (23) positions the wheel carried by it against the other wheel. The central processing unit then orders rotation of a threading motor which by a gear train drives the wire. A cutting mechanism cuts the wire to improve threading. A guide water circuit is provided downstream of the cutting mechanism. |
