Symmetric Beauty: Double-Position Numerical Control Press Based on Lever-Toggle Force Amplifying Mechanism Driven by Linear Servo Motor
According to the conception of symmetric beauty in the aesthetics, a new kind of numerical control press with double operating positions based on lever-toggle force amplifying mechanism driven by linear servo motor is introduced here. Its working principle, characteristic features and mechanical calculating formulas are given also. Compared with traditional mechanical press based on the crank-linkage-slider mechanism driven by common AC motor, the system has following advantages: two operating positions, higher energy transmission and production efficiency, no environmental pollution; lower cost of machine tool. Through rationally designing the acceleration curve of the pressure head, the impacting noise of the system can be reduced greatly. This press is especially suitable for blanking and low-stretching process.
