Hi am suresh i would like to get details on design fabrication of hydraulic sheet bending machine wikipedia ..My friend Justin said design fabrication of hydraulic sheet bending machine wikipedia will be available here and now i am living at hyderabad. and i last studied in the college/school st.mary josaph schol. and now am doing electrical pannel bords fabricaton. i need help on hydraulic sheet bending machine etc

ABSTRACT: Nowadays the world is focusing into automation. Each and every work of human is reduced by a machine,
but few areas like construction the usage of machines for bending rods for stirrups which are used to withstand loads in
beams and columns are not done by machine because the cost of machine is high and need skilled labours to operate it. So
this project is aimed to do bending operation for stirrups using hydraulics and named as hydraulic rod bending machine.
The main objective of our project is to implement the hydraulic rod bending machine in the construction sites with less
cost compared to the existing bending machines, and increasing the productivity of the stirrups. Hydraulic rod bending
machine consist of Double acting cylinder, P-40 Direction control valve, Hoses, Motor, Pump, Rack and Pinion, Free
wheel, Fixture. The rod is bent by the hydraulic cylinder piston with holding the rod in the fixture. The main advantage of
our project is the square shape of the Stirrups is bent continuously without repositioning the rod in the machine.

INTRODUCTION
This project is to bend the rod at the specified dimensions which is used in the building construction which called as
Stirrups. Stirrup is an important reinforced element which acts as a shear reinforcement. Presently, stirrups are made
manually, which suffers from many drawbacks like lack of accuracy, low productivity and resulting into severe fatigue in
the operator. In manual stirrup making process, operators not only subjecting their hands to hours of repetitive motion, but
in many occasions it results into several musculoskeletal disorders (MSDs).
The project is designed based on the principle of Hydraulic system. The hydraulic load has more power compare to the
other type of loads like pneumatic and electric. By using heavy loads we can increase the productivity of the product. The
manual stirrup making process suffers from the many drawbacks. The construction worker not only subject their hands to
hours of repetitive motion but also sometimes suffers internal injury to his body organ i.e. disorder carpal tunnel syndrome
CTS, slipped disc problem etc.
WORKING PRINCIPLE
The system that we propose is that bending of square and circular stirrups. The rod is bent with the help of hydraulic force,
because the power of hydraulics is very large the main aim of our project is to increase the productivity so with the help of
hydraulic force we can able to bend 3-6 rods depending upon the diameter. The drawbacks in the older machines are
rectified. If we place a rod for bending in the existing system we have to reposition the rod for every bend, but in our
system once the rod is placed we need not reposition the rod for all bends. This is done by a special attachment of coupling
the pinion wheel of a rack and pinion set to a freewheel, the function of the freewheel is to change the position of the table
to 900
. When the hydraulic cylinder in the forward stroke the freewheel slips and hold the fixture table at the time the rod is
bent. In return stroke of the cylinder the rack rotates the pinion which is connected to the freewheel turns the table to 900

ABSTRACT

For parametric specification of 3-point bar bending machine, it isnecessary to analyze the stress induced in rollers and gear teeth radial force. Thus Finite element mod-eling is necessary and suitable software must be selected for analysis and observation.There are manyuseful software are available in the market like ANSYS V-13, LS DYNA, ABAQUS and soon. Hence the3-point bending machine consists of number of individual parts which to be model and assembled. The AUTODESK INVENTOR professional 2013 is best suitable for modeling of this machine (AUTODESK provides ease of man-machine interface, mating of parts both transitional to rotational, constrain edge-surface etc.). It also assists for part detailing and presentation.The finite element analysis is carried out using ABAQUS 6.10 for solving stress distribution across the rolling rollers with billet displacement of 67mm, stress distribution with roller rotation, Gear drive analyses for minimum load case without billet and Gear drive analyses for maximum load case with billet thickness. It also requires the gear trainmechanism with the motor to drive roller, to transfer torque to overcome the vertical load acting duringoperation, and speed reduction for ease bending & rolling process. Thus analysis of load acting on thegear tooth is necessary to set the minimum inside radius of roll for 3-roller bending machine.

CONCLUSION

 In latest attempt a successful solution for the manual stirrup making is obtained.
 By changing the fixture in the table we can obtain various sizes of the stirrups.
 Instead of complicated designs the simple kinematic system is used.
 In this system bending of stirrup wire can extended to its length against workstation is possible.
 The rate of production is around 1000 to 1250 stirrups in 8 hours of effective working per day.
 The system can be handled by any operator very easily.
 Due to low cost and simple design this can be marketed to any of the nation.
