POOJARI BOT:

DESCRIPTION : A Tilak stamping machine as per vedic shastra. The tilak is of great spiritual consequence to hindus. Applied tilak on the forehead between the brows. It is a point of immense power and piety. A machine was made by using the Slider crank mechanism for indexing purposes which reduces human interaction. The main objective was to make machinery for stamping and provide a machine with low cost, high accuracy, less floor area, and less interaction of human beings. As it comes under the Kinematics of Machinery. The slider-crank mechanism reduces the floor space while also making the loading, unloading, and indexing simple within one mechanism. Stamping is a process for producing text or images using a master form or templates. Every industry requires stamping to obtain a finished product and to advertise its product to its customers. Stamping of details on the products can be done either manually or automatically. Here we are highlighting the use of a manually working stamping machine that works on the slider-crank mechanism. The Slider-crank mechanism is a particular four-bar link configuration that exhibits both linear and rotational motion simultaneously. Slider cranks are of two types: In-line and offset. Here in this project offset type of slider-crank mechanism is used.Offset: If the line of travel of the hinged joint of the slider does not pass over through the base pivot of the crank, the slider movement is unsymmetric. It moves faster in one direction rather than the other. Tilak makers are not very necessary to make tilak easily And tilak is a medium. It is a point of focus from where you can tap the incredible powers of design of tilak.

COMPONENTS: 1) One DC geared motor 10RPM. 2) Plastic stick multi-hole straight. 3) Two millimeters wire. 4) Twelve bolts. 5) Crack(stand)

Advantages AND Disadvantages:

• Stamping is faster and requires less labor and machine work, so it is the most cost-effective even in the metal forming method today.
• The perfect way to manufacture large quantities of products.
• The stamping process can be completed in less time as compared to stamping done by hand.
• Other mechanisms can be used by replacing the slider-crank mechanism. Compared to an automatic stamping machine, this machine is slow and less productive.
• The product finish is not so good when compared to the automatic stamping machine.
• An automated electric-powered stamping machine is a good option over a manually operated machine.

IMAGE: 

PRINCIPLE: Simple crack mechanism.

WORKING: We set up the machine according to the above image. Their is switch(on and off). When we starts the machine all plastic stick rotates. At the end of the machine there is a one stick(looks like alphabet L). This plastic stick once stamp in tilak container next one stamping the tilak on forehead between the brows.It is the working principle of stamping machine.

Conclusion: So, to conclude in this stamping machine mechanism rotary motion is transmitted through the movable links using pins(rivets) which gets converted into stamping on the datum.
