Compare to the double arm forming machine, the four-arm forming machine usually can work for a bigger coil range in the large AC motor coil forming process. The machine can be customized according to the coil type, coil shape, and automation level.
Starting the machine after input coil forming parameter to HMI, the equipment will automatically control the nose clamp, the straight part clamp. the forming arm and the forming position of the bevel edge to complete the forming process.
CNC servo motor easily solves the coil's rebound problem by controlling the coil span and coil angle through an HMI touch screen.
The equipment has auto distance and centering features to make sure the coils meet the design requirements.
Equipment's clamp can adjust 0-150 degrees. The linear edge and the end corner won't bulge or concave, the clamp locks and won't move in the forming process to ensure no abrasion between coils.
