Abstract : This Project deals with the design of louver die to manufacture the louver .The louver die
perform louvering operation in a single stroke of a punch press, so that a complete component is
obtained for each stroke. Normally, in the blanking process, the product passes through the die and
shutter are created. A die of this type is called louver die.
Keywords: Die, louver
I. INTRODUCTION
LOUVER, A device comprising multiple blades is louver that, permits the flow of air but restict the
entrance of water or other elements. window blind or shutter is Louver which consist of horizontal
slats that are angled slats fixed or hung at regular intervals in a door, screen permit, air or light to
pass through. A structure, which allow openings for the passage of smoke. But it also help to keep
inside surface away from rain and direct sunshine. DIE, Specialized tool used in manufacturing
industries to cut or shape material is Die, it highly using a press. As like molds, dies are generally
made to the product they are used to generate. Its application is varaying from from simple paper
clips to complex pieces used in advanced technology. Tool and die makers helps in producing
forming die and then it put into actual production after accesing keep into press. Metal block that is
used to form materials like sheet metal is a die.
II. MATERIAL USED
It is basically ferrous materials, Mild steel, its physical & chemical property which die required for
working are listed below Carbon content 0.15% to 0.35%, Tensile strength is 1200/1420MPA, Yield
strength is 750/1170 MPA. HCHCr whos Carbon content is 2.10%, Mn content is 0.6%, Si content
is 0.6%, Cr content varying from 11-13%, Density is7.7 ×1000kg/m³, Tensile strength is 1204.65
MPA, Hardness is ranges from 50-55. OHNS whose Carbon & chromium content is 1.0%, Cr0.5%,
Tensile strength is 1200MPA, Yield strength is 400 MPA.

III. CONSIDERATIONS FOR DESIGN OF DIE SET
strength and wear resistant properties should be consider for die design, heat treatment bad effect can
be taken into considseration. Clearance is most important property while designing die so it must be
consider for die desing. Standardised component should be used while designing die. Compatibility
of component should be consider while designing.

FORCE CALCULATION
Cutting force= L ×T× τₘₐₓ

Where, L=length of the periphery to be cut
T=thickness of the sheet
τₘₐₓ =shear strain
τₘₐₓ =0.5 syt /fos
Actual cutting forces =fos ×cutting
forces
STRIPPING FORCE
Presss forece [total force]
TF=C.F +SF
Machine Tonnage
Machine tonnage = A× SF ×T
Clearance
C=0.0032×T×√ (τₘₐₓ/10)
Size Of Die
DIE SIZE =PUNCH SIZE+ 2C
PUNCH SIZE =PART SIZE-ELASTIC RECOVERY OR C
Thickness
FOR DIE PLATE
DIE PLATE =Td=3 √CF
PUNCH HOLDER PLATE
PUNCH HOLDER PLATE =0.5 ×Td
BOTTAM PLATE
Bottam plate=1.5 ×Td
TOP PLATE
Top plate=1.25 ×Td
STRIPPER PLATE
Stripper plate =0.5 to 0.75 ×Td
THRUST PLATE
THRUST PLATE = 18- 19 MM
BENDING FORCE
Bending force=[k ×w×σₘ×T²]/L
Where,
k=1.2to 1.33
ENERGY IN PRESS WORK
E= Fₘₐₓ× Punch Travel
= Fₘₐₓ× k × T
ADVANCE FEED
Advance feed = W+ b
Where, B=1 to 1.25T

Total Deformation
Fabrication of die:
Cutting operations:A variety of cutting processes that utilize shearing forces exist to separate or
remove material from a piece of sheet stock in different ways. Milling:Breaking solid material into
small piceses by using grinding machine. Drilling:Making cylindrical hole into solid material. CNC
Operation: Its is automated machinining process which is done with the help of compouter. Surface
Grinding::Grinding the surface by using grinding wheel. Bolting:
Here we are doing joining of individual component by using fastening device.
VI. CONCLUSION
The design process of louver die to manufacture the louver has been successfully done and various
parameter releated to it has been studied. The louver die are immense importance for a design
engineer, as it is economical and simple. One time investment in the requisite equipment would
ensure a long term supply of superior quality products, generating huge profits for the manufacturers.
