Construction And Performance Test Of An Automatic Pneumatic Sheet Metal Cutting Machine

Abstract

Automated pneumatic shearing machine has been used to shear the sheets made of galvanized- iron and aluminum of various thicknesses. The pressure and force required for shearing these metal sheets have been listed accordingly. Automation in the process is incorporated by using air compressor solenoid valve-controlled roller feed system. The automation provides provision to enter the number of sheets to be cut and required length of the sheet. The system works by pneumatic means which consists of air compressor, pipe lines, control valves and pneumatic cylinder. The design is particularly suited for the applications where working space is contained. Pneumatic systems are useful when sheet metals are need to be cut in hazardous areas such as oil and gas refineries and in chemical factories. Further it is observed that, the employment of automation system makes the cutting process accurate, time efficient and increases the productivity as compared to conventional non-automated cutting machine. Sheet metal is simply a metal formed into thin and flat pieces. It is one of the fundamental forms used in metal working and can be cut and bent into a variety of different shapes. This machine maximum 1 mm sheet can be cut. Here we use a air compressor which is measure the air pressure. It will be control as we need. Countless everyday objects are constructed of the material. When the air coming through the compressor into the system enters the pneumatic system, it creates a lot of pressure. This pressure can be measured through pressure gauge. This can be done by increasing or decreasing the wind speed to reduce blade pressure. This makes it easier to provide the required pressure. The pneumatic valve is fitted with a small pressure gauge which can measure how much pressure is required to cut a metal.
