Servo injection machine dkm-sv50 dakumar-m
The machine use the high-performance servo dynamic control system, the oil pump as power source, having the characteristics as follow: high response, saving energy, low noise, high-control precision, and have the breakthrough
Dkm electro-hydraulic servo system uses the slim motor design which the moment of inertia is small, coupled with the most advanced dsp computing device, to realize the oriented vector control of magnetic field. The system has fast response. Part of the servo motor can reach the maximum speed 2, 500 r/min, and the change of the speed from zero to maximum speed only needs 36 ms. Actions, such as the opening and closing of the mould, injection table movement, ejector pin moving forward and backward, are obviously speed up, shortening the formation cycle time and improving productivity.
Precision
We take the high-precision spinned transformer which reach 4096 pulse/r as the feedback element of motor rotate speed (flow) and take the high-precision tension sensor as the feedback element of pressure. And control the pressure and flow with double-closed loop. Realize various control calculation using high-speed dsp which make it real to keep the average pressure inaccuracy within 0.5 bar and the inaccuracy of rotate speed control within 0.1%, and the hysteresis hoop is zero. Hence, the repeat accuracy of product weight is very high that meet customer's need to pursue the high precision in production.
