Design and Fabrication of Sequencing Circuit with Single Double Acting Cylinder

摘要

This project deals with the construction of pneumatic device assembly for press-fitting a pin to a hole. For press-fitting a pin to hole using a pneumatic device accomplishes a cylinder and a button to operate it. But by accidentally operator may have his hand in the work while operating the cylinder. For this safety issue our design is such a way that it provides an output only when both palm button 3-way valves are operated nearly simultaneously. Through this circuit operator’s safety is ensured. Our project’s main motto is to press fit a pin to hole using pneumatic devices by economically and to ensure the operator’s safety i.e. When starting an operation, accidents such as fingers being caught can be prevented, by requiring both hands to start these palm button operated valves. The solution to this problem is done by connecting two palm button spring return valves connected in series, 5/2 way pilot operator valve and a double acting cylinder.
