Experiment: Control of a Bending Tool

The control system built for the previous experiment can also be designed using a monostable 5/2 directional control valve, to control a bending tool, for instance. In that case, the first cylinder would be used to put one bend a workpiece that had previously been clamped, then the second cylinder would put in a second bend. In this case the control circuitry for each cylinder needs to include latching capability.


Construct the pneumatic circuit shown below and create an appropriate circuit diagram for the control system using the circuit diagram editor (note: normally open switches B1.1 and B2.1 are shown in the diagram in their activated positions). Click on the graphic to open it in a separate window.
