What role punch balancer? Punch balancer role, we must talk about the transmission principle punch, punch power from the main motor. The main motor through V-belt drive is connected to the flywheel to generate energy, and then drive through the press shaft, large gear, crankshaft, connecting rod and spread punches punching action completed. Punch during operation, due to the rotation of the transmission structure inevitably produce inertia, causing the respective drive member because of the gap generated shock, vibration, then it is necessary to balance the inertia via the balancer, which is the primary role of the balancer.
