ROUND WIRE CONDUCTOR END TWISTING MACHINE FOR DC MOTOR ARMATURES (ACM120)

The ACM120 machine is designed for synchronized two-side round wire conductor end twisting by means of coaxial spindles, driven pneumatically through lever mechanism. Inner and outer twisting tools alignment and twisting angle are adjusted using the respective stop screws and a fly-wheel. Handles used for the adjustment are conveniently disposed in the front side of the machine, allowing easy access to the operator. Twisting tools are made out of high-grade hardened and ground steel.
The armature that is to be processed is loaded manually into the changeable centering workpiece seat with wire retaining pins attachment. The round wire conductor ends are fed to the required distance (by means of a pneumatic cylinder) towards the twisting tools. Then the operator closes the wire retaining pins using the respective hand lever. Closing of the retaining pins bring conductor ends to be positioned against the openings of the twisting tools. A pneumatic cylinder retains the hand lever in lower position during the twisting process. The automatic twistng cycle is started by pressing the respective button on the machine control panel(MMI).

Approximate capacity: 300 armatures/hr.
