SD20-400 Electric Program-controlled Screw Press

SD-20 Series Electric Program-controlled Screw Press --The Main Equipment for metal forging WORKING PRINCIPLE: Our SD20 series Electric Program-controlled Screw Press includes Screw Press, Switched Reluctance Motor and with PLC as Core Controlling System. The Press uses Switched Reluctance Motor drive the flywheel move positively and inversely frequently, and then drive the copper nuts and slide up and down by screw to impact. With PLC system control the product forming automatically, through the touch panel screen set the operating parameters digitally. When inputing the signal, the motor begin to work from the state to start very quickly, drive the flywheel and screw rotate acceleratedly, and the screw drive the nut and slide down acceleratedly. When the motor meets the rotate speed pre-set requested by impact power, the Press uses the energy stored by flywheel to impact, which make the product formed. Once after the flywheel release the energy, the motor drives the flywheel rotate inversely at once, return to the set position, the motor come into the stop state, and the mechanical brake stop at the same time to make the slide return to the pre-set stroke position. The controlling system complete the product forming process automatically based on the preset impact speed and impact times , and then return to the pre-set stop position, the work-piece is rejected out and wait for signal to start again. THE CHARACTERS AND ADVANTAGES OF THE PRESS: 1. Impact power control accurately, precised forming, small tolerance and long mould life. 2. Program-control the forging process, the impact power of each step can be pre-set. 3. High efficient and energy saving, the energy consumption can be saved by over 50% comparing to the friction press. 4. With rail and cylindical column guide, 5. Well lubricate, the screw and copper nut are sink in the oil, which can lubri-cate very well, it can expand the life of screw and copper nut 6. No fixed down-die point, no 7. High-reliablity, it will not burn the motor and controller while lack of phase. 8. Wide work table which is easily put mould 9. Small start current, it can reduce the impact to the grid THE FEATURES OF THE PRESS 1. Designed with Point and Work two modes Point mode uses as slowly adjust the mould, Work mode designed with Forming and Slicing Three steps, and also with compensated impacting function 2. The function of setting parameters, it can set the following parameters through Touch Panel: Speed parameters setting Work steps selection setting Time parameters settings 3. Designed with state monitoring function, which is easily checking troubles 4. There are system introduction and operating manual on Touch Panel 5. Concentrated lubrication, designed with Lubrication Pump Station, which ensure well lubricated. 6. Double Brake Function, with motor brake and mechanical brake two brakes function 7. Slide stroke can be adjusted conveniently 8. Long-distance checking troubles SD-20 Series Electric Program-controlled Screw Press is specially used in forging industry for metal forming, it is a strong available forging equipment which is developed based on forging forming requirements of crafts and technics. The Press is applies to: 1. Hot die forging, extrusion, trimming, bending and correction; 2. Precision forging and finishing; 3. The Stainless steel pot bottom pressure and welding; 4. Titanium alloy blades and other blade precision forging.
