DESIGN AND FABRICATION OF PRINTING PRESS MACHINE USING
DOUBLE TOGGLE MECHANISM
ABSTRACT:
A simple yet comprehensive method is proposed for the design of a double
toggle mechanism for operating printing machine. In the proposed approach we are
going to perform the printing operation in the normal paper with one type of printing
tool contain and simultaneously working.
It is easy to perform the number of punching operation in a single drive motor
system it can be replace the punching tool. Finally, a toggle mechanism is fabricated
in order to demonstrate the feasibility of the proposed approach and number of
punching in single drive and time interval system.
INTRODUCTION:
Toggle mechanisms are commonly used within linkages and serve many
purposes. 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. 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.
As the toggle mechanism passes through the toggle position, each of the links
are compressed creating a large amount of force within the linkage. This mechanism
consists of two links, a slide, a stop, and three connecting pins. The two links are
able to rotate about their connecting pins and the slide allows translational movement
During this evaluation, the pin is pushed vertically downward forcing the other two
links to rotate about their endpoints and the slide to translate towards the right.
When the pin is pushed a sufficient distance, such that the adjacent links are
aligned, the mechanism is said to be at its “toggle” point. At this position the
components within the linkage have experienced their greatest compression and
therefore their greatest amount of load.
As the mechanism passes this point, it is said to travel “over-toggle” and the
load within the linkage begins to dissipate. Often this “over-toggle” position is used,
in conjunction with a hard stop for the links, to lock a linkage in place as any forces
from the outside pins would force the middle pin further down and into the potential
hard stop. Additionally, because of the large forces experienced within a toggle
mechanism, there is a component that is compliant and takes some of the stress
created by the interference between the links as they pass into the over-toggle
position. Additionally, the compliant material also provides a constant force back
into the linkage helping lock it into the over-toggle position.
WORKING PRINCIPLE:
This model using double toggle mechanism it is fully link based system, which is
drive to the single drive motor with in rigid link connection. 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.
 This model 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.
