1. INTRODUCTION
Due to increase in globalization it is very important to
produce goods with high precision and high accuracy or
reliability. Metal bending machine is mostly use in
fabrication industry generally using bending machine
produce U-shape and V-shape.Inthedesignofmetal bending
machine we use only three rollers for the bendingofMetal in
different angle due to the number of compost use overall
cost of machine low and machine portabletypethe weightof
the machine is less than is very full portable. Ourprojectisto
design and construct a bending machine. This machine used
to bend Metal into curve or other curvature shape. The size
of the machine is very convenient for portable work. In
various fabrication works as well as in architectural work
Metal are use in different ways. To bend these Metals into
these artistic forms is not easy thing to be done manually.
Using a particular machine specially developed for bending
of Metal help. Choosing component material is very
important, because it will affect the overall cost of the
machine and product quality. With this consideration, we
will design this machine with the maximum quality and low
cost, In Metal during bending operationstress concentration
is occur in bend area of Metal the bend section may be
damage during service in particular case where significant
validity and thickness version exist which are introduce
during menacing process and operation time. Hence the
acceptance of Metal depends on magnitude and shape of
Metal. In Metal bending process the thickness of Metal is
change. The acceptability of Metal bend is depending on
magnitude and shape imperfection. Then we also study on
failure analysis of Metal bend intheseweassumeMetal bend
is uniform thickness.

3.2 Spindle Wheel
Fig – 3: Spindle Wheel
Spindle Wheel is an attachment made to one of the base
roller to drive the system. This will helptoperformrotations
of rollers to obtain uniform pressure over entire affected
area.
3.3 Bearing
Fig-4: Bearing
Bearing is a mechanical element provides support and also
helps to reduce friction during rotations. There is variety of
bearings available for every mechanism. The selection of
bearing should be done on the basis of load applied and area
of application.
3.4 Hydraulic Bottle Jack
Fig-5: Hydraulic Bottle jack
Hydraulic bottle jack is used to provide pressure over
material undergoes bending during operations. This can be
done manually but there will be some limitations arise for
applying forces.
3.5 Fastener & Hinge
Fig-6: Fasteners & Hinge
We are going to use different types of joints and
screws for assembly of this machine.
4. OPERATION & WORKING
The working of this machine is very simple to perform.
The basic principle of operation is to apply pressureover the
pipe or metal by using hydraulic system. We are going to use
hydraulic bottle jack for this purpose. A pipe or metal
undergoing bending operation should insert from one end of
the machine through the rollers provided in particular
manner as shown in figure above. When this metal got
inserted, the rotating operation gets started. After specific
rotations the pressure should started to apply in upward
direction, which helps to move end side body in upward
direction. This movement of end side body results in the
formation of deflection of pipe or metal inserted.

9. CONCLUSIONS
This project will work effectively with designed
specifications. This will also helpful to perform bulk
operations. This project is done with the hope of providing
cheap and easier way to perform such operations. This will
be economical and efficient too. Such type of bending
machines are more important for small scale work aswell as
industrial work in less cost and more precisionandaccuracy
of different type of pipe bending. The machine capacity can
be increased according to the need. Manual bendingtends to
minimize wrinkles and can reduce springbuck. By its design
the defects can be easily overcome. Simpler design not only
reduces the defects but alsocontributestofluidpressuretest
during bending.
Thus, this approach can be used for bending a thin
walled tube over a small radius of the die, which can be
achieved with a conventional method of bendingthetube. In
this paper, the problem of bending and axial stretching the
internal pressure is investigated using the machine
coordinate system(CMM)measurement.Theobjectiveof the
study is to develop a tool that accurately predicts thechange
of the wall thickness and the cross-section of the tube
distortion under different loading conditions.

B. Patil College of Engineering, Indapur, Maharashtra, India ---------------------------------------------------------------------***---------------------------------------------------------------------- Abstract - The main purpose of the research paper is to explain the design and developed hydraulic powered roller bending machine. It is used for Construction, Aerospace, and Automobiles & Industrial. It’s time consumption process. It reduces human effort and also required low less skill to operate this machine. We are designing hydraulic powered roller bending machine with use of roller, bearing, hydraulic jack, & support (frame). The objective of the subject istomake new design of manually and hydraulically operated roller bending machine and stress acting on Metal after bending of Metal. The Metal bending machine is use to bend Metal in different angle shape and curvature as requirement of work. The machine is useful to bend different thickness Metal as per the requirement of shop. The machine is fully portable type and less weight and easy to assembleanddisassemble. Thecan operate unskilled operator. Key Words: Roller, Hydraulic Bottle Jack, Fabrication, Bending Operation 1. INTRODUCTION Due to increase in globalization it is very important to produce goods with high precision and high accuracy or reliability. Metal bending machine is mostly use in fabrication industry generally using bending machine produce U-shape and V-shape.Inthedesignofmetal bending machine we use only three rollers for the bendingofMetal in different angle due to the number of compost use overall cost of machine low and machine portabletypethe weightof the machine is less than is very full portable. Ourprojectisto design and construct a bending machine. This machine used to bend Metal into curve or other curvature shape. The size of the machine is very convenient for portable work. In various fabrication works as well as in architectural work Metal are use in different ways. To bend these Metals into these artistic forms is not easy thing to be done manually. Using a particular machine specially developed for bending of Metal help. Choosing component material is very important, because it will affect the overall cost of the machine and product quality. With this consideration, we will design this machine with the maximum quality and low cost, In Metal during bending operationstress concentration is occur in bend area of Metal the bend section may be damage during service in particular case where significant validity and thickness version exist which are introduce during menacing process and operation time. Hence the acceptance of Metal depends on magnitude and shape of Metal. In Metal bending process the thickness of Metal is change. The acceptability of Metal bend is depending on magnitude and shape imperfection. Then we also study on failure analysis of Metal bend intheseweassumeMetal bend is uniform thickness. 2. CONSTRUCTION Fig-1: Construction of bending machine The model of this project consists of following main components o Bending Rollers o Spindle Wheel o Bearings o Hydraulic Bottle Jack o Housings o Screw o Moving Roller o Supporting Frame o Mounts o Joints & Fasteners 3. CONSTRUCTIONAL DETAILS Here we are going to discuss over few of very important components required for this machine in details. These are as follows, 3.1 Bending Roller Fig -2: Bending Rollers Bending is to be done on sheet metal or metal bars, thus we are going to use solid steel bars as a roller.

This will helptoperformrotations of rollers to obtain uniform pressure over entire affected area. 3.3 Bearing Fig-4: Bearing Bearing is a mechanical element provides support and also helps to reduce friction during rotations. There is variety of bearings available for every mechanism. The selection of bearing should be done on the basis of load applied and area of application. 3.4 Hydraulic Bottle Jack Fig-5: Hydraulic Bottle jack Hydraulic bottle jack is used to provide pressure over material undergoes bending during operations. This can be done manually but there will be some limitations arise for applying forces. 3.5 Fastener & Hinge Fig-6: Fasteners & Hinge We are going to use different types of joints and screws for assembly of this machine. 4. OPERATION & WORKING The working of this machine is very simple to perform. The basic principle of operation is to apply pressureover the pipe or metal by using hydraulic system. We are going to use hydraulic bottle jack for this purpose. A pipe or metal undergoing bending operation should insert from one end of the machine through the rollers provided in particular manner as shown in figure above. When this metal got inserted, the rotating operation gets started. After specific rotations the pressure should started to apply in upward direction, which helps to move end side body in upward direction. This movement of end side body results in the formation of deflection of pipe or metal inserted. 5.

APPLICATIONS o Used in small and large-scale industries for metal rod bending operation. o Used in civil engineering for bending pipes. o Used for manufacturing of steering wheels, round bars etc,. o Used in Automobile vehicles. o Used in various fabrication applications for home decors. 8. FUTURE SCOPE o In a future this machine can be operated by using Electrical, Pneumatic, and supply. o We can be used for different curve and different shape of pipe. o This machine is design by using two or more pulley arrangement. o Movable stopper is used to give more accuracy. o Pipe bending machine is higher initial cost involved we have tried to make the system cost effective and also add different enhancement to make thesystem more efficient so that it may work around the year. 9. CONCLUSIONS This project will work effectively with designed specifications. This will also helpful to perform bulk operations. This project is done with the hope of providing cheap and easier way to perform such operations. This will be economical and efficient too. Such type of bending machines are more important for small scale work aswell as industrial work in less cost and more precisionandaccuracy of different type of pipe bending. The machine capacity can be increased according to the need. Manual bendingtends to minimize wrinkles and can reduce springbuck. By its design the defects can be easily overcome. Simpler design not only reduces the defects but alsocontributestofluidpressuretest during bending. Thus, this approach can be used for bending a thin walled tube over a small radius of the die, which can be achieved with a conventional method of bendingthetube. In this paper, the problem of bending and axial stretching the internal pressure is investigated using the machine coordinate system(CMM)measurement.Theobjectiveof the study is to develop a tool that accurately predicts thechange of the wall thickness and the cross-section of the tube distortion under different loading conditions. 10.
