Hard Tooling Terminology
COMBO DIE / FULL CLASS "A" / BLANKING DIE
FOR THE STEEL RULE DIE INDUSTRY
Description of types or hard tooling
1: A "Combo Die" consists of half male/female and half steel rule or a machined punch.
This tool cuts Interior accurately and the exterior at steel rule quality.
2: The Full Class "A" cuts with interior/exterior shear cuts and includes stripper plate.
This tool cuts both the interior and the exterior very accurately.
3: Blanking Die Has Only The Male/Female Portion.
This tool cuts the slug which is usually the part needed.
Hard Tooling Die Nomenclature:
A: Stripper plate
This is a solid machined plate backed up by die springs for a positive removal of die cut part from the punch. This plate is used in combo dies as well as full class "A" dies. the part is put back into the web.
B: Shedder plate
A plate is in the upper male punch of a Class "A' die to remove the die cut part and then put it back into the web.
C: Male/Perforator
The male is the interior punch which may be a shape or a diameter that has to enter into the female.
D: Female/Platen
This plate is on the bottom of the die set and it contains all the diameters and/or shapes for the male/s to cut through and the outer die punch to cut against.
E: Female
The female has the same shape as the male for which it must pass through.
F: Stop blocks
These protect the die from over stroking and damaging the tool.
G: Upper die shoe
This plate holds the die punch, males and the stripper plate.
H: Lower die shoe
This plate holds the female.
I: Ball bearing bushings
These are used when there is high tolerance between the male/female to prevent contact and also for a long die run.
J: Standard bushing
The standard bushing is used when a lower tolerance between the male/female is not required and a short die run.
K: Pin/Post
The pin/post enters the bushing for proper alignment before the male(s) enter the female.
L: Die life
Die life is the amount of vertical shape the die has. The greater the die life the more the slug has to travel before exiting.
M: Lift rings
Used to lift the die when moving.
N: Shank / Spud
Used to attach to the ram of the press.
O: Stroke (Inches)
The amount of movement the press has in vertical motion.
P: Punch
This is the outer portion of the tool usually a steel rule die or a machined punch.
Q: Punch retainer plate
This holds all the males in location for exact aligniment to enter the female.
R: Sub plate
Used to make up distance for proper shut height.
S: Die springs
Die springs are of exceptional quality for use in the return of the stripper plate or the return of the upper die shoe.
T: Spring return
If the die set is to be returned under its own power. This aids in having not to bolt the upper die plate to the press.
U: Parallels
To lift the die set for scrap removal when there is no scrap hole in the press.
V: Pilot Punch
Used to locate the material when doing progressive cutting.
W: Set-Up Block
This block is used with a feeler gage to adjust the press for proper engagement.
