When the busbar processing machine completes the punching, cutting and bending operations, errors are unavoidable. In order to further process the accuracy, for the error, the method of minimizing the error is adopted. The following is an introduction to the method of reducing the error of the busbar processing machine.
CNC busbar processing machine is a new type of mechanical equipment, which can well promote the rapid development of industrial production. Therefore, it is very important to choose a high-quality CNC busbar processing machine. So, what tips should be mastered when choosing mechanical equipment? The following is a brief introduction to some of them.
1. The influence of tool error. On the machining center, since the adopted tool has an automatic exchange function, it also brings tool exchange errors while improving productivity. When using the same tool to process a batch of workpieces, due to the frequent and repeated tool change, the tool holder has a repeated positioning error relative to the spindle taper hole, which reduces the machining accuracy.
2. After the busbar punching and shearing machine starts normally, the incoming line switch of the busbar punching and shearing machine should be turned on automatically. At this time, the DC system, uninterrupted power supply system, emergency lighting and security power supply motor control center should be adjusted immediately to ensure its power supply. reliability.
2. The influence of the repeated positioning accuracy of the machine tool. The positioning accuracy of the busbar processing machine is the position accuracy of each coordinate axis of the index control machine tool under the control of the system. The factors that cause the positioning error include the system error and the mechanical transmission error. The system error is related to interpolation error, tracking error and so on. The repeated positioning accuracy of the busbar processing machine refers to the degree of conformity between the actual position of the coordinate axis and the ideal position during repeated positioning.
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.
2. Plunger pump
Regarding the error of the busbar processing machine, we can reduce the error as much as possible through the above method.
The moving parts of the three units of punching, shearing and bending need to be lubricated before work, once in the morning and in the afternoon; the get off work surface and each unit are required to be oiled and maintained before work; punching dies, shearing dies, bending dies Lubricating oil needs to be rubbed every 20 times of work.
The faults of the busbar processing machine can generally be divided into circuit faults, mechanical faults, and hydraulic system faults. During the use of the busbar processing machine, the failures caused by the hydraulic system are relatively common. Among them, the failures of the hydraulic circuit can be interdependent. When troubleshooting, it is necessary to combine the circuit and oil circuit schematic diagrams, carefully analyze and treat them in detail, and pay attention to circuit failures. First cut off the power of the whole machine.
