Under what circumstances need to use a dual-machine linkage bending machine
The dual-machine linkage bending machine is mainly used for various small and medium-sized enterprises, and its secondary feature is that it consists of two parallel movements, hydraulic cylinders, vertical downward pressure, and a bending die duty on the bending beam when driving. It is reminded that the CNC hydraulic control system of the horse is mainly to control the bending process and the synchronization of the hydraulic cylinder to locate the position when the plate is fully loaded.
The movement cycle stages of the operation process of the dual-machine linkage bending machine are:
(1) The bending beam of the motion position of the motion shape bending machine is at the upper death point. In order to avoid uncontrolled downward movement, the system uses a leak-proof back pressure valve to block the rod cavity of the hydraulic cylinder.
(2) Downward movement The fast blocking movement under the great bending machine is mainly the free landing method, which is the movement of each bundle of the bending machine and accessories. In this process, the back pressure of the rodless cavity of the hydraulic cylinder will occur after the rod cavity of the hydraulic inlet valve. Fast forward rate 250mm/s) proportional to the valve open loop or closed loop control. Moving forward quickly from the point of death, after a long-lasting braking phase,
Blocked from the largest curved plate from 6 mm. All kinds of differences require different bending machines are coming to an end.
(3) Stamping/bending stamping/bending stage from no rod cavity pressure. The punching rate is limited on the one hand of the oil pump oil, on the other hand, the ratio can be adjusted.
