High Speed Portable Pipe Cutting Machine SYNOPSIS

1. Title of the project : High Speed Portable Pipe Cutting Machine Introduction: The above sequence if observed has the human intervention through out the process is necessary and more over the process of bar cutting does not add to the value of the  product hence can be treated to be an idle time. Thus there is an attempt in the form of continuous cutting off machine to reduce the idle time to a minimal value. In the machine once the bar stock is fed to the stopper the machine automatically feeds the cutter to the work piece until it is cut to the required length during the cutting stroke and during the return stroke the bar will automatically fed to the stopper by the machine itself , and so also the clamping of bar stock during cutting stroke and de-clamping being done by the machine itself. The sequence of operation is as follows: 1.eed bar stock to stopper that is set according to length of work piece to be cut. !. "lamp the bar stock #. eed the cutter blade to cut the required length. $, %etract the cutter  &. 'e-clamp the work piece(.procedure repeated

Solution : The solution to the above problem is the development of a low cost automation based machine using a pro)imity sensor to sense the *ob feeding + for semi-auto model feeding the *ob to length is manual . ..further clamping , cutter feed , cutter retraction , de-clamp operations are automatic and fast (

or!ing : The sequence of operation for the machine is as follows: 1. eed *ob to length. !.ro)imity sensor senses the *ob,(..circuit is /0 #. "lamp cylinder operates to clamp the *ob $. "utter feed cylinder operates to feed cutter in downward direction to cut the *ob(.feed rate is ad*usted using flow control valve. 2. ress  345 63TT/0----4ensor is by-passed (this makes circuit / &. "lamp cylinder reverses stroke ---*ob is de-clamped 7. "utter feed cylinder reverses (..return strokes are faster to save idle time. 8. eed *ob again (..continue steps 1 to 7

Con"tructional #eature" : 1. Cutter $otor and cutter head :  "utter motor is 199 watt motor variable speed 9 to 8999

rpm ..with a standard 1:# ratio gear head thus output speed of cutter will be !&99 to 9. %. &inear "lide and cutter feed arrange$ent:

inear slide comprises of two linear motion

 bearings on wither side with guide bars and set op helical compression springs. The feeding action is done by a double acting pneumatic cylinder (.speed of the piston in forward direction ie, the cutter feed is controlled flow gradual cutting action

using a flow control valve in

is achieved using a set of clamps namely , the set- clamp + ad*ustable to accommodate different

si
feeding action is manual ie, the *ob is fed in the *ob guide manually upto stooper. , the pro)imity sensor is used to sense the *ob. The sensor then actuates the electrical circuit comprising of an electronic 8-pin relay and push button system.. *. Pro+i$it, "en"or and electrical circuit

ro)imity sensor and the electronic relay circuit is a simple electrical circuit used to sequence the operations in the circuit , it can also be replaced by an limit switch arrangement(.but sensor is more reliable (.the circuit decides the on=off of the 2=! way direction control valve in the  pneumatic circuit and thereby the clamping=cutting =return action. -. Pneu$atic circuit:

neumatic circuit uses two double acting pneumatic cylinders , one 2=! way direction control valve and one flow control valve., functions of the above components have already being e)plained above. *.

Objectie":

The ob*ectives of this pro*ect are,

The concept of group pro*ect was included in our engineering syllabus with the view to inculcate within us the application ability of the theoretical concept of design and production engineering to practical problems . 4o also to help us to learn to work more as a team rather than an individual.

In completing our pro*ect titled"/0TI03/34 "3TTI0> / ?@"5I0A  as per our  time estimate gives us immense pleasure and a feeling of achievement. 'uring the course of   pro*ect we encountered numerous problems which we overcame with the able guidance of our   pro*ect guide.

This pro*ect report presents a brief mention of our efforts . ro*ect work has given us good e)posure to the practical field which in the future is definitely going to help us
