The Hydraulic control form,Maintain and Design of Busbar Bending Machine
Hydraulic Control Form
The hydraulic control system of the Professional busbar bending machine is the central brain of the Professional Busbar Bending Machine itself. In the production of the bending machine, a high rate of automation and standardization is required. Therefore, the hydraulic system is also limited to hydraulic control methods, and the different structural types and principles of these methods have been generally recognized by the market.
1. Central control block
The form of the central control block is to synthesize three control blocks into one control block. It is mainly used in some special structure Professional Busbar Bending Machines. Due to control reasons, the connecting pipes between the control block and the two stamping hydraulic cylinders must be symmetrically arranged, and the maximum allowable distance between the two hydraulic cylinders must be guaranteed (about 3m). Therefore, the central control block should be arranged as much as possible in the center of the machine.
2. Three control blocks
This style has three control blocks. The two main control blocks with associated intermediate plate filling valves are mounted directly on the hydraulic cylinder, enabling a pipe-free connection between the main control block and the cylinder chamber. The main control block of the Fully Automatic Busbar Bending Machine is mainly composed of important proportional directional valves, position monitoring directional valves and back pressure components.
3. Interface distributor for sensor and shaft
In the application of the Fully Automatic Busbar Bending Machine, the central control block concentrates all the solenoid valves in one control block. Similarly, the electrical connections of each valve are concentrated on one cable to realize the common connection. For this reason, an interface distributor is also set up on the central control block of the bending machine.
Maintain
Before machine tool maintenance or machine cleaning, the upper mold should be aligned with the lower mold and then put down and shut down until the work is completed. If it is necessary to start the Fully Automatic Busbar Bending Machine or other operations, the mode should be selected in manual and ensure safety. Its maintenance content is as follows:
1. Hydraulic oil circuit
a. Check the oil level of the fuel tank every week. If the hydraulic system is repaired, it should also be checked. If the oil level is lower than the oil window, hydraulic oil should be filled;
b. The hydraulic oil used is ISO HM46 or MOBIL DTE25;
c. The oil should be changed after 2000 hours of operation of the new machine, and after every 4000-6000 hours of operation, the oil tank should be cleaned every time the oil is changed;
d. The oil temperature of the system should be between 35°C and 60°C, and should not exceed 70°C. If it is too high, it will cause deterioration of oil quality and accessories.
2. Filter
a. Every time the oil is changed, the filter should be replaced or cleaned thoroughly;
b. If the machine tool has related alarms or other filter abnormalities such as dirty oil, it should be replaced;
c. The air filter on the fuel tank should be checked and cleaned every 3 months, preferably replaced every 1 year.
3. Hydraulic components
a. Clean the hydraulic components (substrate, valve, motor, pump, oil pipe, etc.) every month to prevent dirt from entering the system, and do not use detergent;
b. After using the new machine for one month, check whether there is any deformation at the bends of the oil pipes. If there is any abnormality, it should be replaced. After two months of use, the connections of all accessories should be tightened. pressure

Design
First of all, you need to determine the specifications of the Nice Quality Busbar Bending Machine you want to design
Generally speaking, WC67Y series is used for those below 200T, WD67Y series is used for those above, and WD67Y series is also used for long models.
1. Determine the tonnage and maximum bending length of the bending machine. 2. According to the form and parameters of the national standard bending machine, find out the maximum opening height, slider stroke adjustment, throat depth, and working speed~.
2. Determine the diameter of the oil cylinder (the key is directly related to whether the nominal pressure can meet the requirements). It can be calculated according to the system pressure of 24.5MPa. The stroke of the oil cylinder is determined according to the maximum opening height you have found out. The size of the oil pump and motor can be determined according to the working speed.
3. Determine the thickness of the slider and the vertical plate of the workbench~ According to the calculation of the deflection and deformation formula of the sheet metal, the maximum deformation is controlled at about 15 wires~ The thickness of the wallboard can be taken as the thickness of the slider~~ The width of the workbench is twice the lower mold width
4. The design of the hydraulic part should be designed according to the following actions: fast down, slow down, pressure maintaining, unloading, and return.
5. Other parts are secondary but necessary
In short, a Nice Quality Busbar Bending Machine must have the following parts
1. Frame part 2. Stroke adjustment mechanism 3. Slider mechanism 4. Synchronization mechanism 5. Back gauge mechanism 6. Upper and lower mold centering device 7. Hydraulic system 8. Electrical system
