Tool with a void or cavity that is precisely fitted to a punch used to metals to the shape of the tool itself |
Die |
|
plate or block on which the die is mounted |
Die holder |
|
condition resulting from any forming, piercing, hardware inserting or spot welding operation too close to an edge |
Edge Bulge |
|
The removal of a part from a die by an air blast or mechanical means |
Ejecting |
|
Metals containing of a part from a die by an air blast or mechanical means |
Ferrous |
|
the damaging of one or both metallic surfaces by removal of particles from localized areas due to seizure curling sliding friction |
Galling |
|
The degree to which a metal will resist cutting, abrasion, penetration, bending and stretching. |
Hardness |
|
Subjecting metals to heat treatment |
Heat Treating |
|
A wear plate used on the heel block |
Heel plate |
|
Ease of machining metal |
Machinability |
|
Developing a very hard case after a ling time at comparatively low temperature, without quenching |
Nitriding |
|
where a tool or alloy steels are quenched in oil as the quenching medium in the hardening process |
Oil Hardening |
|
a Block of steel or welded construction to which punch steels or punch retainers are mounted, also called a punch riser |
Pedestal |
|
To cut, shear, or punch an opening in sheet metal, strip, plate or parts such as a slot or hole |
Pierce |
|
individual die part that contains one or more pierce holes or die buttons |
Pierce Block |
|
small cylindrical die steel with an opening larger than the punch point size |
Pierce Button |
|
perforator, or specific name for a punch that falls in the cutting punch category |
Pierce Punch |
|
the direction from which a tool or punch enters the workpiece |
Punch Direction |
|
An indication hardness test based on the depth of penetration |

|
Process of cutting or tearing a hole in metal, which does not generate a slug. Instead, metal is pushed back to form a jagged flange on the backside of the hole |
Spear punching |
|
a metal heat treatment process to remove internal stresses at temps above those required for stress relieving |
Tempering |
|
the most longitudinal stress steel can sustain without breaking |
Tensile Strength |
|
any high carbon alloy steel capable of being suitable tempered for use in the manufacture of tools |
Tool steels |
|
V Shape tool used of angle forming |
V Punch |
|
a steel used in various forming operations in which a narrow metal strip at the edge of a sheet or metal part is bent down a straight or curved line. also referred to as flange steel |
