Equipment technical performance and parameter description
1. Equipment survey
The control system of straight line tuning type wire drawing machine developed by Jiangyin Hengyi Electromechanical Co.,Ltd. adopts the AC freq. con. speed adjustable drive, controlled by PLC. The international most fashionable PROFIBUS on-site bus mode is adopted with stable and reliable running, low energy cost, the production efficiency is improved largely. It is suitable to draw the spring steel wire, tyre ring wire steel, rope making wire steel, optical fibre wire steel,CO2 gas shield welding wire, flux-cored wire, alloy steel wire, S.S. wire, al. coated steel wire as well as low relax prestressing steel wire, etc.
2. Equipment performance
2.1 Reliability: For electric control system, the international fashion PROFIBUS on site technology, controlled by whole digital control. All electric elements are international famous brands. The operation of electric control system runs stable and reliable.
2.2 Energy saving: AC frequency speed adjustable drive is adopted to reduce the impact to mechanical stroke. Meanwhile, it can reduce the energy cost by over 30%.
2.3 Safety: with multiply protection function, when the equipment runs in high speed so that the protection shell is opened and other trouble takes place, the equipment speed is reduced till stop.
2.4 Convenient: For each set, there are functions such as positive and negative inching, front linkage, rear linkage function. There are length preset display at main operational pulpit man-machine interface, speed preset display, trouble inquiry, equipment status display, computer die arrangement.
2.5 Low noise: for main drive, we adopt the hard gear surface speed reducing box + narrow V combination belt or two steps narrow V combination drive, reduce the driving noise effectively.
2.6 High efficiency: reduce the trouble taking place rate, improve the average working speed, improve production effectiveness largely.
2.7 Environmental protection: The wire drawing machine is whole enclosing design. The negative pressure principle is used to collect the dust produced when the steel wire is pull up draw and gather dust into the dedust equipment through air pipe. It improves the working environment when the steel wire pull and draw and remove the dust powder pollution during steel wire drawing course.
2.8 Outer visual: the outline of equipment is optimization for its structure, designed according to platform, meet to the international fashion, the same as or better than the imported equipment.
