SD10 Series Elektro-Programmgesteuerte Screw Pres

This series Program-controlled Electrical Screw Press is the main special equipment of non-metallic and metallic materials’ forming, it includes Screw Press, Switched Reluctance Motor(SRM) and PLC operating system. The key part, Switched Reluctance Motor is doubly salient structure, both stator and rotor(12-stators/8-rotors pole) is made by ordinary silicon steel layers. The rotor has neither windings and permanent magnets, the stator teeth are concentrated winding around the pole. The controller includes embedded microprocessors, programmable logic devices, IGBT driver circuits, power electric devices, software and communication interfaces to complete motor drive and control. The motor winding current direction has no relation with phase shift, which only depends on the sequence of phase winding power. The motor has following characters and advantages: 1. Can be frequently start and stop, positive and inversion switch, the motor will not damage; 2. Starting current is small, and starting torque is large (small current, large torque), 30% of rated current can reach 1.5 times rated torque, small impact to the power grid; 3. Wide scope of adjusting speed, can be adjusted between 50-3000 rpm; 4. High reliability. Locked rotor and lack of phase will not burn the motor and controller (More Safe!); 5. Power factor can reach above 0.98, reactive loss is small; 6. High efficiency. High and low-speed operation can both maintain the high efficiency. The Press uses Switched Reluctance Motor drive the flywheel, the sleeve spindle of flywheel and copper nuts frequently move positively and inversely, which drive screw and slide move up and down to impact. With PLC system, it control the product forming automatically, through the touch panel screen set the operating parameters digitally. Comparing to the old fashioned Friction Press, SD series Program-controlled Electric Screw Press has the following features and advantages: The good quality of product forming and consistency with qualified rate. It can be digitally and programmable set the impacting power, make analog manual operation, first soft and then hard; Accurately control the energy and hitting power, the Switched Reluctance Motor adjust speed in high precision, small error, and input energy of Press is accurate;Short transmission chain, simple structure, small consumption parts and convenient maintenance in low cost. With no two friction discs, the motor drive flywheel directly in positive and inversed which make the slide move up and down to impact;High degree automation which can reduce the manpower. Program-control the forming process, push-button operation, reduce the labor intensity;Efficient and energy saving. The motor works when impacting, but when feeding, brick out and cleaning mold, the motor doesn’t work. Compare to old style friction press, it can save energy about 30%--50%;High safety. With three brake methods: Mechanical brake, Compressed air brake and Electric brake, and it also equipped with Emergency-stop button, which ensure the slide can be stopped at any position; Reliable, safe and durable.Types Data SD10-315SD10-400SD10-630SD20A-630SD20A- 1000PN(KN) 315040006300630010000Max Pressure(KN) 63008000125001250020000Slide stroke(mm) 600750750500700Die Height(mm) 780920115011501250Strokes(r/min) 2020181815Work Table Size(LxWxH) (mm) 940x800x 1001100x950x 1201250x1120x1501000x1000x1501200x1200x200Machine Size(HxWxB) (mm) 4200x3500x 20004750x3800x21005410x4300x24005540x4060x24606540x4460x2660Total Weight(T) 17 28 45 45 72 Motor Power(KW) 37 5575 75110
