This machine is designed to punch holes for spiral binding of the A4 size documents (papers). The punching machine consist of series of slender punches, penetrates in die holes and bunch of papers are placed between the fixed stripper plate and die, and hole are punched at its prerequisites position by the application of force manually applied force with the help of a lever. The punches together are mechanized by connecting links providing mechanical advantage to the manually applied load. The main features of this machine are portable in size, easy in operation and maintenance and economical in cost. Design, working drawing with specification and animation of machine assembly is checked and tested in SOLIDWORKS drafting and designing software to increase in productivity in design, after design manufacturing and final testing of the actual working of the all the assembled parts. Finally, selecting and working on this project provides us as a diploma engineering student, an opportunity and vision to accomplish more bigger tasks in machine tool industry, technical know-how of designing and manufacturing, cost estimation, and putting a cost effective, durable, easily maintainable product in today’s competitive market.

The different lies in the process that is use to achieve the result. Paper drills are powered by motor can handle large stack of paper. Paper punch are manual device for putting holes in smaller quantity of paper and physical smaller in size. Custom hole punches can be designed for your specific requirement. B.S.PATEL POLYTECHNIC, KHERVA 2014 SPIRAL BINDING PUNCHING MACHINE Limitation: It can punch only 39 holes. It cannot cut metal sheet. It required high load for punching on paper. It can punch only medium quantity of paper. B.S.PATEL POLYTECHNIC, KHERVA 2014 42 SPIRAL BINDING PUNCHING MACHINE 43 Innovative Ideas If method of finding midpoint side of sheet is time consuming and requires much effort one has to use his both handles to match the two corner of the sheet and then apply pressure at failed to give total impression after that one has to slide or stack of sheet and put it one stack as stack of sheet into holes punch light shield midpoint indicator and fold impression before actuating the punch lever. The punch of the punching machine are very high quality it can cut metal sheet. We can cut extra size of paper and metal sheet by using blade attached beside of machine. With use of pneumatic system we can punch very speedy. We can punch more paper and spiral with increasing size of machine. Punching machine are operated by computer with connected it. Punching can done fast and automatic with hydraulic system. Metal sheet can be cut and punch by using laser light in punching machine. B.S.PATEL POLYTECHNIC, KHERVA 2014 SPIRAL BINDING PUNCHING MACHINE 44 Applications Paper punch machine equipment handle large document heavy punching load and feature convenient auto capabilities to prevent jams. A semi-automatic electrics paper punch are heavy duty paper punch machine can handle other documents of many different project. Electric hole punches machines and paper punch machine offer to ability to change the patterns designed with unparalleled efficiency the electric punch machine feature another changeable die modules. Present patents pending hand operator hole punch machine are used to punch holes through the paper sheets or sketch of sheets to keep all punched sheets. Field in well-arranged manner. It is manner necessary that all the sheets have holes at the same location.

The main things we learnt from this project is understanding the concept of design, tooling, designing software like creo, chart making, estimating and costing, manufacturing etc. B.S.PATEL POLYTECHNIC, KHERVA 2014
