Development Of Automatic Processing Machinary For Cable Car Rope

In recent years, with the rapid development of China's automobile industry, the demand of the cable wire rope grows accordingly. The cable wire rope processing industry is a labor-intensive industry, which requires a large amount of labor. Over the past few years, because of the rising labor costs in Jiangsu and Zhejiang provinces and the enormous pressure of industry transformation, automation of manufacturing process and minimizing the labor costs is an irresistible trend. Consequently, reducing production cycle and costs are the main factors for companies to improve working efficiency and product competitiveness. The key problem in the design of the cable wire rope automated production lines is the scheme design of the whole system and the design of the control system to improve the system stability, production efficiency and product quality.Firstly, the production process of cables wire rope is introduced, including wire rope cutting, playing flower, die-casting and cleaning edges. According to processing technology, a new cable wire rope automated production line is developed. The relevant parameters are calculated and some components in the key stations of the system are selected.Secondly, in order to improve the stability of the system and the production efficiency, a mathematical model of cantilever floating manipulator in the feeding mechanism of the rotary table is constructed. The manipulator is seen as a cantilever beam consolidated on a rotating rigid body. Through discretizing manipulator into a limited degrees of freedom system, its natural frequency and main vibration mode are calculated by the matrix iterative method. The analysis in the ANSYS is conducted to verify the correctness of this model, which provides a theoretical basis for the design of the cantilever beam, and lays the foundation for subsequent modeling and simulation in the ADAMS.Then, the discrete flexible body model of the cantilever floating manipulator is developed in ADAMS to analyze the dynamic characteristics of the manipulator's tip in different movement patterns. The reasonable movement rule is selected, and the vibration model and parameter optimization of the manipulator's tip are conducted to provide a theoretical basis for the reasonable design of spring stiffness and tip mass.Finally, the control design of the cable wire rope automatic processing system is completed based on PLC core technology. It includes hardware design, software design and human-computer interface system design, forming a "pneumatic- Sensors- PLC- man-machine interface " of automated control systems.
