---------------------------------------------------------------------***--------------------------------------------------------------------Abstract - Now a days the world is focusing into automation. The paper is designed based on the principles of Each and every work of human is reduced by a machine, but pneumatics and the system is automatic type. By using few areas like construction the usage of machines for bending automation the productivity of the product can be increase. rods for stirrups which are used to withstand loads in beams 2.LITERATURE SURVEY and columns are not done by machine because the cost of machine is high and need skilled labours to operate it. In this 1.I Muhammed, S.Ravivishwnath, P Sureshkumar , N. paper is aimed to do bending operation for stirrups using Sarvanan Design and fabrication of hydraulic rod bending pneumatic and named as pneumatic rod bending machine. machine, April 2014. Worked on design and fabrication of rod bending machine and they concluded that Each and The main objective of our paper is to implement the pneumatic every work of human is reduced by a machine, but few areas rod bending machine in the construction sites with less cost like construction the usage of machines for bending rods for compared to the existing bending machines, and increasing stirrups which are used to withstand loads in beams and the productivity of the stirrups. Pneumatic rod bending columns are not done by machine because the cost of machine consist of Pneumatic cylinder, Compressor, Hoses, machine is high and need skilled labours to operate it. So this Pulley, Cutting blades, Fixture, Electronic circuits, Switches project is aimed to do bending operation for stirrups using and wiring .The rod is bent by the Pneumatic cylinder piston hydraulics and named as hydraulic rod bending machine. The main objective of our project is to implement the with holding the rod in the fixture. The main advantage of our hydraulic rod bending machine in the construction sites with paper is the square shape of the Stirrups is bent continuously less cost compared to the existing bending machines, and without repositioning the rod in the machine. increasing the productivity of the stirrups. Keywords: bending operation, pneumatic system, Stirrup, manual stirrup making, fixture.
2.Vilas Shinde, Darshan Adhav, Suraj Jadhav, Afsar Attar, Sandip Gorde. Design and fabrication of hydraulic stirrup making machine, May 2016.They worked on Design and Fabrication of Hydraulic Stirrups Making Machine and they concluded that Since testing the stirrup making machine it is observed that how much time is required to make single piece of stirrup by effective working. The detail description is given as below: Loading and unloading combining clamping the bar to fixture it almost takes only 5 to 6 seconds. Time required to forward and backward stroke is about 10 to 11 seconds during which stirrup is made. Considering machine ergonomics that is interaction of human operator with machine, it is very easy to operate it because operating switch is provided at suitable place of machine. Again loading and unloading is not complicated since not very specialized tooling is used it is very simple structure.
1.INTRODUCTION Since long time ago the labour work has essential role in constructions including mixing coarse aggregate-sandwater- cement, ramming sand, land levelling, and digging the foundation for base of structure, cutting rod in required length, rod bending and pouring the mixture of concrete in columns and beams. Now days, due to development in technology it is required to reduce the labour work and time since there are lot of available resources. As population increasing very rapidly, demand of the construction to build the buildings for industries, overhead bridges, human livings and population is continuously increases. Several problems come in to the picture when we consider human work with respect to automation. By using conventional method it is not possible to reduce construction time and building it as early as possible. So, Automation in construction system is requires.[4]
