3. We have come up with the idea to do something interesting with mechanisms.
We're thinking to build a Printing Press by using Double Toggle Mechanism.
There has been a serious demand for intermittent printing in the industries right from the
start. Though the continuous printing is more or less important in the same field.
The mechanism to be developed in its simplest form would perform the function of
printing operation in the normal paper with one type of printing tool contain and
simultaneously working.
The objective of our project is to produce a mechanism that delivers this printing operation
as well as punching operation using mechanical linkages.
The advantage of our system over it is easy to perform the number of punching operation
in a single drive motor system it can be replace the punching tool over the printing tool.
4. Toggle mechanisms are commonly used within linkages and serve many purposes.
1. Toggle mechanism, combination of solid, usually metallic links (bars), connected
by pin (hinge) joints that are so arranged that a small force applied at one point can
create a much larger force at another point.
2. These purposes include transferring rotational motion into linear motion,
magnifying input loads (due to the mechanical advantage that a toggle mechanism
affords), and locking the position of a linkage.
3. In all of these applications, the links within a toggle mechanism experience a great
deal of stress, especially when used to lock the position of a linkage.
5. The minimum number of independent variables required to define the position and motion of
the system is known as degree of freedom of the system.
OR
Degree of freedom is the number of input required to get constrained output in a chain.
In figure ,
F = 3(L - 1) - 2J - H
Where F = degree of freedom L = no of links J = no of binary joint H = no of higher pair
Hence,
F = 3(6 - 1) - 2*7 - 0
F = 1
6. 1. This Mechanism using double toggle mechanism it is fully link based
system, which is drive to the single drive motor with in rigid link
connection.
2. The full rotation crank lever connecting on motor it is rotate
continuously which concreted into up and down motion on press tool
using on double toggle mechanism.
7. This mechanism has totally having six
link, starting point connecting on motor
crank link.
Second link joint together rigid link and
press tool.
Third link acting on rigid link.
Fourth is connecting on second and third
one.
Then, Fifth link connecting another one
of rigid link.
Sixth one is connecting on press tool.

8. We will design the prototype of pressing machine with the help of CATIA Software.
In the CATIA V5 R2016 ,we used several command like sketch, pad, pocket
,revolve , etc for the designing of prototype.
This design consists of two phases:-
1)Design the Frame
2) Design the mechanism.
17. Large, medium and small scale industries.
Educational institutions.
Banks and other government sectors.
Commercial purpose.
18. Time saving machine.
High accurate operation.
Maintenance is easy.
Less manual power.
Reliable
