WPN series CNC Winding Press Machine

The WPN series CNC winding press machine produced by Beijing Precision Engineering Institute for Aircraft Industry is a large-scale transformer winding production equipment with new structure and performance. With the combination of mechanical, electrical hydraulic system and computer control, it can support accurate axial pressure for transformer winding to meet the requirements of design and process in axial dimension of transformer winding.

Characteristics:

1）Four cylinders linked with top platform are used to provide down pressure， reliable running and convenient maintenance.
2）Pressure on winding is from internal pressure, which can be used to lessen the recline on strength of foundation.
3）Hydraulic system is designed with both low pressure oil line and high pressure oil line. Low pressure oil line means long travel and fast feed. High pressure line means short travel and precise feed. High pressure return oil line is designed with accumulator, which can reduce the vibration.
4）The simple operation, high pressing precision, accurate pressure control operation of safety and reliability can be acquired by servo-control on hydraulic system by CNC system.
5）Multi-layer safety protection functions (for example, accidental power failure during pressing winding) can be achieved.
6）The computer control system can record the data of position and pressure during pressing winding automatically to facilitate query for production later.
7）Selective function and auxiliary parts: accidental power failure module, winding transportation equipment (rail carrier, electrical forklift)etc.
