The busbar processing machine is a bending machine controlled by a numerical control system. The machine itself has only one basic movement—up and down reciprocating linear motion. The structure design is relatively simple, mainly composed of four parts: the material blocking mechanism, the worktable part, the synchronization system, and the slider part, which is easy to operate and has high work efficiency. The following editor will specifically explain the structure of these four basic parts of the busbar processing machine.
One is to use an auto-converter for compensation. Usually, an auto-converter is installed on the current transformer on the transformer side, and the LH output end is connected to the input end of the converter. When changing the transformation ratio of the auto-converter When , the output current of the converter can be made equal to the secondary current of the LH without the converter, so that the current flowing into the differential relay is zero or close to zero.
1. Material stopper mechanism: The material stopper is driven by a motor, and the two screw rods move synchronously through chain operation, and the numerical control system controls the material stopper size;
1. During the operation of the motor, if dust, water stains and other debris enter it, a short-circuit medium will be formed, which can destroy the insulation layer of the wire, resulting in a short circuit between turns, increasing the current, and increasing the temperature to burn and destroy the motor. Because of this, dust, water stains and other debris should be avoided from entering the motor. At the same time, the outside of the motor should be cleaned frequently. Do not let dust and other debris in the heat dissipation ribs of the motor to ensure that the heat dissipation state of the motor is unpleasant. satisfy
2. Synchronization system: The busbar processing machine is a mechanical synchronization mechanism composed of torsion shaft, swing arm, joint bearing, etc., with simple structure, stable and reliable performance, and high synchronization accuracy.
3. Before starting the machine, close the C45 switch on the inner side of the power distribution box of the machine, turn on the "control power" key switch and turn on the red light on the control board, indicating that the power is turned on, and then according to the type of work, the control switch of the corresponding station can be turned on, and the green light is on , the equipment enters the normal working state, start the foot switch according to the actual needs when processing incoming materials, and automatically return to the original state after the station travel is in place (Note: This function is controlled by the proximity limit switch, and the shutter can be adjusted by yourself to set what you want work station itinerary).
3. The worktable part: operated by the button box, the motor drives the material stopper to move back and forth, and the distance of the movement is controlled by the numerical control system, which can be read as 0.01 mm;
Including laying in high-rise building cable shafts to facilitate power supply to users on all floors. When the plug-in busbar is laid horizontally, the distance from the ground shall not be lower than 2.2m. The closed, plug-in busway is a combined structure, and the standard section (generally 3m in length) is supplied by the manufacturer in a complete set.
4. Slider part: The busbar processing machine adopts hydraulic transmission, and the slider part is composed of a slider, an oil cylinder and a mechanical stopper fine-tuning structure. The left and right oil cylinders are fixed on the frame, and the piston drives the slider to move up and down through hydraulic pressure. The mechanical stop is controlled by the numerical control system to adjust the value.
The data acquisition card is used to collect the analog quantity of the displacement pressure during the bending process. Process and analyze data. The data is calculated by calling the cubic spline function in Matlab and the displacement, velocity, acceleration and bending during bending are plotted. pressure curve. Analyze the bending springback law during the bending process of the busbar. The control scheme of the bending system uses a programmable logic controller (PLC) as the control core. In addition to the basic control program, the CNC busbar processing machine also adds a PID control algorithm, which improves the PID algorithm to make the busbar bending machine system more effective. The PID parameters were adjusted by Matlab simulation to set the optimal control parameters.
