Abstract
The aim of this project is to design a hydro-pneumatic power press using low cost automation.
This project mainly emphasizes on reduction of working time and labor cost. The working time should be reduced in order to increase the productivity of any industry. Labor cost reduction is also very important nowadays, so that even small scale industries can afford to go for automation.
The press that we have designed has proved to provide large tonnage capacity in small size. It also decreases the fatigue of the operator by reducing the consumption of human work. This device also ensures safety of the operator s hand as Two Hand Safety system is included in the circuit.
Pneumatic power is used in this press for all movements as air is a cheap power source and also it is readily available. Pneumatics also ensures safer operation and ease of fabrication of components. For Punching operation alone hydraulic power is used in order to obtain very high pressure and to avoid fluctuation.
The cost calculation for various raw materials and for all the machining operations are performed, also an analysis has been performed to calculate the deflection and stress distribution on the supporting members and the results are enclosed in this paper.
