CTU□ - □□ Swing clamp Swing clamp Double acting Standard model Positioning pin groove for clamp arm Hydraulic pressure (G port piping) Hydraulic pressure (manifold piping) Hydraulic circuit diagram For flow control valve, we recommend the meter-in control. If meterout control is used, due to the area difference, it will cause back pressure and become high pressure. This can Flow control valve model VCF (option) lead to malfunction of the system. Please be aware when designing the circuit. Swing angle 30 , 45 , 60 page → 20 Long s

Double acting Swing clamp Swing clamp Swing speed adjustment Swing time is restricted by the mass and length of the clamp arm (moment of inertia) since the 90 swing action impacts the cam shaft. Example of calculation for moment of inertia 1. Calculate the moment of inertia according to the arm length and mass. 2. Adjust swing speed with flow control valve to ensure that 90 swing time of the clamp arm is greater than the shortest swing time in the graph shown below. I ：Moment of inertia (kg·m2 ) m ：Mass (kg) ● The cam groove may be damaged in case the swing speed is set at the nonusable...
