In sum, AC servo numerical control electrical fly press of the present invention, compact conformation, parts are few, and driving-chain is brief; Have functionality of quick response, overload capacity is powerful, realizes Forming Equipments flexibility and intellectuality, and the improve production efficiency and product high quality mechanical power is excessive, and is vitality-conservation; industrial press machine, Stressed good, simple to manufacture, easy to maintenance, value is low, and is simple to operate; The components loss is little, operates steadily, and the anti-bias load ability is strong, and forming accuracy is high, and is safe and dependable; Lengthy service life has wide selection of functions, and low-pace large does not have impression to electrical community.
Patented within the year 1900 by Valerius Anderson, the flights on the screws of those presses have interruptions which decrease co-rotation. In typical friction driven system (friction screw press), introduction of encoder to detect flywheel revolution for controlling revolution power improved forming stress repeatability drastically.
Background know-how prior electrical fly press is switched on when work repeatedly, and starting is frequent, and kurtosis often appears in electric load; Dash present is large, and power factor is decrease, and it is relatively more serious that the motor feels scorching; Temperature rise may be very excessive, and energy loss is massive, thereby the motor of selecting for use is also very big; With the intention to forestall that motor from burning out, also to use air blast in the cooling of ceaselessly ventilating of whole working time, complete power of motor of set up is huge; As a result of the required complete vitality of each run are all obtained by electrical community in second, subsequently, very massive to the electrical community impression, specification is massive more, and is also just big extra to the influence of electrical addition, the driving requirement of incompatibility Giant Electric fly press low-pace big.
Speeds and pressures may be carefully managed. Producer of Disc Friction Screw press machine utilized in manufacturing clay tiles, refractory bricks, Clay bricks etc. The strike power may be set precisely in response to the molding precision, can cut back the time of mechanical stress and die touching scorching piece, thus delay the die life.
The absence of a backside lifeless centre eliminates the opportunity of sticking the press when the fabric is oversized, too cold or misplaced. In LS Heavy Industry Engineering Co., Ltd., drive system of AC asynchronous motor based mostly on direct torque control technology is efficiently utilized in electrical screw presses.
