ACKNOWLEDGEMENT

It gives us immense pleasure to represent the report on

HYDRAULIC BENDING MACHINE. We like to express our heart full

thanks, gratitude and appreciation to our guide Prof. A.A. PATIL sir for this

timel, careful and valua!le guidance "ith constant inspiration.

We take this opportunit to offer our sincere thanks to #. $.

%. of &echanical %epartment Prof. PATIL P.'. and principal of our college

Prof. %($ ).). for providing us help in course of our pro*ect report.

We "ould also like to thank him for sharing his kno"ledgeon this su!*ect ,"ithout him the completion of this pro*ect seemed impossi!le.

Last !ut not the least ,"e "ould like to thank the almight

god "ho made us capa!le of "ithstanding all the difficulties that occurred

&an device of mechanical are !ased on hdraulic

po"er. #draulic device uses principles of fluid static and fluid kinematics are

used for either storing the hdraulic energ and then transmitting "hen

needed or maintaining the hdraulic energ several times and transmitting

the same.

In all such machines, po"er is transmitted "ith the

help of a fluid, "hich ma !e "ater or oil. $ur mechanism is used in industrial

fitting and maintaining department, in automo!ile garage or in industrial

"orkshop.

$ur pro*ect is used for reducing manufacturing cost

and saving time and also to reduce maintaining cost or a manufacturing cost.

#ere "e manufacture a light "eight 2 eas to handle

machine so that ou can carr an "here into the shop. It is also simple for

assem!ling and disassem!ling.

HYDRAULIC JACKING SYSTEM:-

#draulic *acking sstem is ver eas "orking and gets

result ver fast. In hdraulic *acking 1 tons, 0 tons, : tons,+8 tons, +1 tons, is

standard part and availa!le in market.

We have used 0 tons *acking sstem. This sstem lifts 0

tons of load .In our pro*ect re@uiring !ending load of :88 "hich "ill !e more

than sufficient for fine "ork.

#draulic energ is mainl used for "orking a hdraulic

*acking sstem. ?ut in our mechanism this energ is used for !ending pipe.

$ur machine is used in industrial fitting and as plum!ing

instrument. $ur pro*ect is used for reducing manufacturing cost and also to

save time thus reducing manufacturing and fitting time.

In our machine there are mainl four parts. This parts are stated !elo"B

+. ?ase Plate

1. )upporter Plate

0. pper Plate

9. Locking Plate

1. BASE PLATE :-

The Plate is used for mounting purpose. We drill 9 holeCs

to cutter side and also 9 holeCs in center for mounting *acking sstem as "ell as

"e "eld the *acking sstem to the !ase plate.

!. SUPPORTER PLATE :-

)upporter plate is mounted on !ase plate "ith help of !oltCs.

These plate is standing on ?ase plate. This plates

forms a support for the plates. it also holds the pipe "hich is to !e !end.

". UPPER PLATE :-

pper Plate is mounted on supported plate. These plate is

mounted on upper side. pper plate !alances the pro*ect and get po"er for

!ending.

WORKING OF HYDRAULIC JACK

1$%&'i*+, ,ig

!*&'i*+, ,ig

1) 1ST CYLINDER WORKING:

The hdraulic *ack is a device for lifting heav load !

the application of much smaller effort. It is !ased on pascalCs la", "hichstates that intensit of pressure is transmitted e@uall in all directions through

a mass of fluid at rest.

It consists of clinder DfixedE in "hich the piston slides.

The lo"er end of the piston carries a mova!le plate "hich moves up 2 do"n

"ith the piston the upper 2 lo"er stationar plate are *oined ! column.

When li@uid under high pressure is supplied to the

clinder, the piston moves up"ard 2 applies tremendous pressure De@ual to

the product intensit of pressure supplied 2 area of the ramE on an material

placed on it.

!) !ND CYLINDER WORKING :-

When the piston approaches the end of itCs stroke in

the direction of force, itCs force of fluid into the drilled passage. 6lo" of fluidpast the needle value is restricted so that the piston velocit is reduced. This

prevents the piston from striking the clinder end. The slo"ing of the piston

motion is called deceleration.

6luid entering the connecting part of the rod end passes

directl ! the lip of the cushion seal 2 applies energ at the face of the piston

11


12/39


for !ringing the ram !ack in position, the fluid from clinder is taken out

su!se@uentl the ram in over up ! the action at return "eights.

To raise the main ram rapidl, fluid is pumped The smaller

inner ram, called *ack ram, has a greater area than the lip of the main ram.

/linders 2 rams are often !uilt as an integer part of a

machine slide or press element.

(@ual pressure through out the circuit provides a sta!iliFing

influence in the main ram assists the reiteration of this ram.

In all such machines po"er is transmitted "ith the help of afluid "hich man !e a li@uid "e can use !ut mostl oil is po"erful means that

"hen choosing a hdraulic fluid, the follo"ing factors must !e considered

spread of operation, surrounding atmospheric conditions, economic

conditions, availa!ilit of replacement fluid, re@uired pressure level, temp.

-ange, contamination possi!ilities, cost of mission lines in "hich the fluid is

used safel to operates and expected service life.

#draulic fluids have specific characteristic that can affect

the associated components. i.e. seals, coaching, parking and diaphragms

must !e made !e of a material that "ill not deteriorate in association "ith the

"orking fluid.
