| dc.description.abstract | Pneumatics systems are extensively used in a wide range of industries,
factories and manufacturing sector entities. Pneumatics system are noted for their
simplicity, reliability, and ease of operation. Also they are suitable for fast and rapid
application of force. The purpose of this project is to therefore design a simple, easily
operated pneumatic sheet metal cutting and bending machine that is sturdy and strong.
A pressure of 8-10 bar is enough for operating the unit. The pressurized air passing
through the tubes to the cylinder, forces the piston out whose power through the
linkage is transmitted to the punch. The work piece thus got is for required
dimensions and the piece can be collected through the land clearance provided in the
die. The die used in this is fixed such that the die of required shape can be used
according to the requirement. Automation of machine is achieved with the help of
pneumatic system. This involves the design of an efficient system which reduces the
human effort and help to increase production output. Usually the sheet metal cutting
machine is manually hand operated for medium and small scale industries. The piston
is connected to the moving cutting blade which his used to cut metal. This sheet
cutting machine can cut sheet maximum 1 mm thickness with shearing blades which
length is 375 mm and width 38 mm at a pneumatic pressure of 3 bar and its material is
mild steel. The design and fabrication of pneumatic sheet cutting machine is totally
economical in human effort and useful in small and medium sheet metal industries | en_US |
