Design and Fabrication of a Special Purpose Hydraulic Press Performing Punching Operation
Abstract: Hydraulics has proven to be the most efficient and economical system adaptable to aviation. First used by the ancient Greeks as a means of elevating the stages of their amphitheaters, the principles of hydraulics were explained scientifically by the seventeenth century scholars Pascal and Boyle. The laws discovered by these two men regarding the effects of pressure and temperature on fluids and gases in confined areas form the basis of the principle of mechanical advantage, in other words, the why and how of hydraulics. The word hydraulic is derived from two Greek words hydro meaning liquid or water and Aulis meaning pipe or tubing. Hydraulic, therefore, is an adjective implying that the word it modifies is in some major way concerned with liquids. Examples can be found in the everyday usage of hydraulic in connection with familiar items such as automobile jacks and brakes. As a further example, the phrase hydraulic freight elevator refers to an elevator ascending and descending on a column of liquid instead of using cables and a drum. On the other hand, the word hydraulics is the generic name of a subject. According to the dictionary hydraulics is defined as a branch of science that deals with practical applications (such as the transmission of energy or the effects of flow) of a liquid in motion. Here we are designing a hydraulic punching & bending machine. We followed following some steps in this project are- 1- Study the concept of hydraulic machine and hydraulic press.2- Selection of the product which we are making through this machine.3- Selection of the operations which we have to perform on it.4- Selection of the dies which we use for it.5- Selection of different number of part through which we create machine.6- Selection of material for each part.7- Calculation and the forces analysis of those parts.8- Selection of the software on which these parts are design.9- Making the different views of that part in the auto-cad software.10- Making the design of those parts in pro-e software and solid work software.11- Finally assembly of those part should done in the pro-e software.
