2. Objectives
1. To cater to the issue of competition in mechanical industry the need for
automation is assess by all the industry.
2. To identify the key policy avenues considered to be appropriate to meet the
challenge of sustainable manufacturing and packaging industry for the future.
3. To provide alternative for industries aiming toward reducing human effort and
improvement in material handling system by implementing automation.
4. Sustainable and practical automation solutions for the future industrial
environment.
3. Abstract
The Pedal Powered vertical Hacksaw Machine is a device which is used
for cutting wood, plastic and metals. The basic principle of this machine is slider
crank mechanism, which is an inversion of four bar mechanism. The concept of this
mechanism is that the rotary motion is converted into reciprocating motion. The
mechanism has four links connected to form sliding pair. Thus when one link is
moved along the circumference of the circle, the final link will generate the sliding
movement for cutting process Paper, PEDAL POWERED VERTICAL
HACKSAW machine which can be used for industrial applications and Household
needs in which no specific input energy or power is needed. This project consists of
a sprocket arrangement, the crank and slider mechanism, the chain drive. In the
mechanism, chain drive is directly connected to the hacksaw for the processing of
cutting the wooden blocks. The objective of the paper is using the conventional
mechanical process which plays a vital role. The main aim is to reduce the human
effort for machining various materials such as wooden blocks, steel, PVC etc.
4. DESCRIPTION OF THE COMPONENTS
Pedal arrangement
Stand setup parts
Supporting frame
Crank and slider mechanism
Hacksaw assembly
Sprockets
7. WORKING PRINCIPLE
The cycle frame is fixed with the base mild steel by the process of
welding the chain sprocket is connected to the cycle frame and it is connected to
the pedals. The one end of the chain is connected to the big sprocket and the other
end is connected to the small sprocket which is held in a chain hub. The other end
of the hub is fixed with the small chain sprocket .From the other end of the hub
another chain is connected to the sprocket and other end is connected to another
small sprocket which is held with the circular rod and bearing setup. The circular
rod is inserted into the bearing and is welded with the sprocket at one end and with
rotating disc at the other end. The connecting rod is connected to the rotating disc at
one end and to the hacksaw at the other end. The hacksaw moves in from motion
when the pedal is powered, so as the rotating disc rotates. The vice is fixed at the
top of the frame
8. CONCLUSION
This project focused on modeling, design and control of Bi cycle based
hacksaw, with emphasis on lightweight, portable appliances. . An innovative
method of minimizing manual stress and thus reliably stabilizing the pumping
was also presented. The project carried out by us made an impressing task in
the industrial purpose. It is very useful for the small scale works.
This project has been designed to perform the entire requirement task,
which has also been provided.
9. ADVANTAGES
Efficiency
Effective working principle
It does not havThis is of compact in size
Less Maintenance is enough
Quite running and smooth operation is achieved.
Higher e any Prime mover, like electric motor related to the unit.
Less Maintenance
LIMITATIONS
It is costlier than the other types.
Less efficiency when compressed to other device.
