Abstract

Aluminium is one of the most used materials in the modern world. Starting from industrial oriented purposes to normal day to day usage, aluminium and other sheet metals are playing a great role. Sheet metals such as galvanized iron, aluminium etc. are widely used and are often cut by using hand-oriented techniques such as cutter machine or cutting blades etc. This is generally hazardous to workers and takes a lot of time to do the job precisely and accurately. A lot of small-scale industries are using sheet metals and the cutting and bending operations required to be done in such materials normally makes it a tedious one. It consumes both time and work force. This project aims at eliminating all these to the maximum by making this process an automatic work. Hence reducing a lot of time and work force in small and medium scale industries. Our project is very cheap and portable meeting the expectations of a small to medium scale industry by designing it to be cheaper and at the same time to be cost efficient. The main principle behind this is to use a pneumatic piston to operate the cutter and bender providing the cutting force through the upward and downward stroke obtained by the in and out entries of air from compressor by using a solenoid valve. The solenoid valve is operated by an IC electronic timer circuit. The operation speed is also controlled by a resistor. The cutting force produced is enough to produce shear on material whose shear force is less than 733.6N. Hence a wide range of sheet metals can be cut easily quicker and avoids fatigue over the material since the job is done in a single stroke. Also cutting and bending operations can be simultaneously done at the same time while the machine is working and so the job is completed at a very high rate when compared with man work. The machine can work either in battery or through direct power source, designed to be at a portable size with less weight and hence highly portable. Thus, sheet metal cutting and bending operations are automated and cost efficient by this project making it desirable for small to medium scale industries.
