In order to ensure the normal operation of the CNC bus processing machine equipment and prolong the service life of the machine, it is necessary to carry out a maintenance.
3. The influence of the detection device. The detection feedback device, also known as the feedback element, is usually installed on the workbench or lead screw of the busbar processing machine. The detection feedback device converts the displacement of the worktable into an electrical signal and feeds it back to the numerical control device. If there is an error compared with the command value, then Control the table to move in the direction of eliminating the error. The numerical control system can be divided into open-loop, closed-loop and semi-closed-loop systems according to the presence or absence of detection devices. The accuracy of the open-loop system depends on the accuracy of the stepper motor and the lead screw, and the accuracy of the closed-loop system depends on the accuracy of the detection device. The detection device is an important part of the high-performance busbar processing machine.
1. The shearing unit of the busbar processing machine adopts a general double-knife shearing, and the notch is smooth and free of burrs.
hydraulic part
3. The machine tool coordinate cannot find the zero point. It may be that the zero direction is far from the zero point; the encoder is damaged or the wiring is open; the grating zero mark is shifted; the zero return deceleration switch fails.
1. Check the hydraulic oil level. If the hydraulic oil is too low, oil should be filled in time to avoid damage to the oil pump; 2. Clean the bottom of the oil tank; 3. Clean the filling port;
The above is the introduction of the difference between the busbar processing machine models, I hope it can be helpful to you.
4. Check whether the hydraulic pipeline is smooth, whether there is aging and leakage;
5. Check whether the pump works abnormally;
1. According to the number of hydraulic pump groups, it can be divided into: 1. Single pump: three processing units of punching, shearing and folding work in sequence;
6. Check whether the pressure values of the hydraulic unit are normal; 7. Check whether the pressure gauge joints are loose; 8. Check whether the hydraulic components are damaged;
Electrical parts
1. Clean the electric control cabinet;
2. Check whether the heat dissipation state of the electrical cabinet is good; 3. Check whether the terminals in the electrical cabinet are firm;
4. Check whether the electrical components are damaged and whether the contacts are blackened, and replace if necessary
5. Check the aging of the power cord;
6. Check whether the switch buttons work normally; 7. Check the temperature rise of the motor and check the heat dissipation; 8. Check and debug the numerical control system, and upgrade the processing machine part if necessary.
Punching, shearing and bending parts
1. Check that the wire insulation is good;
2. Check the sharpness of the cutting edge of the shearing machine. If the blade is found to be blunt, sharpen or replace it in time; 3. Check whether the mold is reliable;
4. Check whether the machine tool fasteners are loose;
5. Lubricate the joints and moving parts of punches, shears and bending machines;
6. Check whether the working pressure value of punching, shearing and bending is normal; 7. Check whether the fastening bolts are firm; 8. Check the working performance of the foot switch;
