How to select dual CNC tandem plate press brake bending machine
From the functional Add Newpoint of view, the dual machine linkage CNC tandem plate press brake bending machine is certainly much stronger than the ordinary CNC tandem plate press brake bending machine. If enterprise customers use this double click CNC tandem plate press brake bending machine, it can not only improve product productivity in a short time, but also ensure product quality.
Cost benefit analysis
Compared with ordinary CNC tandem plate press brake bending machine, dual CNC tandem plate press brake bending machine is not only powerful, but also simpler and clearer to operate. For enterprise customers, after purchasing this tandem plate press brake bending machine, they do not need to spend too much time to let employees learn the operation method, which can also save human resources. And in the later stage, if there is personnel turnover, training new employees will not be very complicated.
In addition, in terms of maintenance, although it is a new product, the dual machine linkage will not bring significant maintenance difficulties. On the contrary, due to the addition of technology applications, maintenance is much simpler than ordinary CNC tandem plate press brake bending machine.
What are the characteristics of the double machine linkage hydraulic plate tandem plate press brake bending machine
The double machine linkage tandem plate press brake bending machine is mainly used for various small and medium-sized enterprises. The second feature is that it is composed of two parallel movements, hydraulic cylinders, vertical downward pressure, and the bending die obligation of the bending beam on the drive. Reminder: The CNC hydraulic control system is mainly used to control the bending process and synchronize the positioning of the hydraulic cylinder when the plate is fully loaded.
The movement cycle stage of the double machine linkage tandem plate press brake bending machine operation process is:
(1) The moving shape of the bending beam at the moving position of the tandem plate press brake bending machine is at the upper death point. In order to avoid uncontrolled downward movement, the system uses a leakproof back pressure valve to block the rod cavity of the hydraulic cylinder.
(2) Downward movement The fast blocking movement under the great tandem plate press brake bending machine is mainly in the way of free landing, that is, by every movement of the bending machine and accessories. In this process, the back pressure of the hydraulic cylinder rodless chamber will occur after passing through the hydraulic inlet valve rodless chamber. The proportion of the fast forward speed (250mm/s) tends to be controlled by the open loop or closed loop of the valve. Quickly move forward from the upper dead point, after a prolonged braking phase, lock from the maximum bending plate to 6mm. All kinds of different requirements The tandem plate press brake bending machine with different requirements is almost at the end position.
(3) At the end of the stamping/bending stage, the pressure from the rodless cavity is applied. The stamping rate is limited by the oil pump on one hand, and on the other hand, it can adjust the inclination of the proportional valve. At the same time, the inclined valve controls the synchronous utilization of the bending beam and the position of the lower dead point. The blasting pressure limit is achieved by a limited proportional relief valve pump pressure. Corresponding speed, synchronous positioning, from CNC machine tools and pressure set values.
(4) The rod cavity of the double machine linkage tandem plate press brake bending machine depressurizes or reaches the lower death point, probably at the end of a long time, so the deformed material flow will occur for a certain time, how can you further improve the dimensional accuracy of parts. The proportional directional valve for pressure and pressure reduction is completed according to the instructions of the CNC board.
