Short Description:

The core of transformer is the heart of transformer. HJ series core cutting machine is specialized equipment for production of transformer cores;It process the lamination of yoke, leg, center leg and etc. The equipment adopts the automatic control system, operation easily, high automation and precision. Its manufacturing quality directly affects the performance and operation of transformer. The processing technology of the core, the composition of the production of the core cutting line, the operation method, the precision adjustment, the flatness of the silicon steel sheet, the shearing precision, the burr tolerance and so on all have certain influence on the core shearing machine.

Product details:

The transformer shear production line adopts multiple sets of AC servo system. Respectively used in: material transmission channel by servo motor to set material width in screen operation and automatic positioning. Shearing and v-notching adopt AC servo motor as driving power, with fast response speed, low noise, small vibration, convenience maintenance.
