Product instruction

The hydraulic control system of the hydraulic bending machine is a central brain for the bending machine itself. In the production of the bending machine, a high automation rate and standardization rate are required. Therefore, the hydraulic system is also limited to hydraulic control methods. The different structural types and principles of these methods have been generally recognized by the market.
1. Central control block
The central control block form is to combine three control blocks into one control block. It is mainly used in bending machines with certain special structures. Due to control reasons, the connecting pipes between the control block and the two stamping hydraulic cylinders must be arranged symmetrically, and must not exceed the maximum allowable distance between the two hydraulic cylinders (about 3m). Therefore, the central control block must be arranged as much as possible in the center of the machine.
2. Three control blocks
This style has three control blocks. Two main control blocks with associated intermediate plate filling valves are mounted directly on the hydraulic cylinders, creating a pipe-free connection between the main control blocks and the cylinder chamber. The main control block of the bending machine is mainly composed of the important proportional reversing valve, position monitoring reversing valve and back pressure components.
3. Interface distributor for sensors and axes
In the application of the central control block in the bending machine, all the solenoid valves are concentrated in one control block. Similarly, the electrical connections of each valve are also concentrated on a cable line to achieve a common connection. For this purpose, an interface distributor is also provided on the central control block of the bending machine.
