ABSTRACT:Traditional machine tool is the use of relay logic circuit for automatic control of the process, in use due to electrical failure often makes maintenance time increases, the productivity gains. Further more failed to meet the accelerating demand of modern product updates. Therefore, this article will be the traditional power sliding system to optimize the design and control upgrades. Systems used in hydraulic power systems; abandon the traditional relay control programmable logic controller in the control. After optimization and up grading of control can improve production efficiency, to keep up with the pace of information technology, automation era.
Designed power slide is a combination of well-known machine tool part, hydraulic cylinder driving can be realized in situ to stop fast-forward → a work into the → - two workers into the → died block of iron to stay → rewind → 6 working the status of automatic control. Above the sliding table can be placed in a variety of special cutting head can also be placed power box, slide bed, middle, Low Block, generic parts can be composed of various combinations of machine tools for the completion of drilling, expansion joint, boring, milling, car, tapping and other processes.
The combination of machine power slide study design includes two hydraulic system design and PLC control system design.
The first is the analytical calculation and design of the hydraulic system. The article with step-by-step one by one method of calculation, described the combination of machine power sliding hydraulic system design. After research and analysis to develop throughout their design process: system analysis → design technical requirements and design parameters → conditions → to determine the system parameters → the development of the hydraulic components of the hydraulic schematic diagram → Select → Check of hydraulic system performance. To sum up all the process is complete the entire design of the hydraulic system.
Follow by the PLC control system design. Order to be able to complete that part of the design, designed in the first analysis, the hydraulic system designed to simplify and analyze, understand its transmission and hydraulic system works. On this basis, then the hardware and software design. Hardware and software design including: the choice of the PLC model, the distribution of input and output points, wiring diagrams and instructions. Software design including: the design of the software flow chart, written in ladder design and instruction sheet.
Through this design, the final combination of hydraulic system schematic, the ladder program of PLC control system and the corresponding instruction sheet.
