Technical Topics
1. Utilizing ISO8020 Head-Type
Punches – a real advantage
3. Ball Lock Punches – an
economical solution
5. Ejector Punches – eliminate
problems
7. General Suggestions for
Improving the Metal-Stamping
Process

Head Type Punches
• Here is a commonly used punch…the
DIN9861-D
• Old Design based on inexpensive tool
steel
• German standard
• Aimed at close spacing
• Relatively easy for a toolmaker to make
up in case of emergency repair
• Today it is still widely used thanks to the
presence of European tools across the
world
• There is a better solution that saves the
toolmaker time and money
11
The ISO8020 Head
Type Punch
• Standard Body Diameters – allows many
incremental point diameters on just one
body diameter. This allows toolmaker to
machine pockets of equal diameters thus
reducing preparation time.
• Consistent Head Diameter and
Thickness – Again this allows a toolmaker
to machine the pockets for the heads much
more quickly and efficiently.
• Designing and Procurement -The above
features also allow faster designing and
easier purchasing
• Let’s illustrate these points more clearly by
examining the next slide…
12
Let’s consider that the die requires 3 punch
diameters – 6.4mm, 7.0mm and 7.5mm
• If the toolmaker chooses DIN9861 punches, he must
prepare 3 different seats in the die as can be seen below
• Not only does he have to drill 3 different hole
diameters but he must also prepare 3 different head
thicknesses (x,y and z) and thus 3 head diameters
• If the toolmaker chooses an ISO8020 punch then he
prepares 3 equal punch seats as can be seen below
• He simply orders 3 punches with an 8mm
body diameter…each having the required point
diameters of 6.5mm, 7.0mm and 7.5mm
13
Ball Lock Punches
• Invented for the Automotive market
• Designed for “Quick Change”
replacement of worn or broken punches
• There is no need to disassemble the die
– Punches can be changed while the die is
in the press
• Affixed to the die by being inserted
into Standard Ball Lock Retainers that
are “Interchangeable” within the industry
• “Special” Ball Lock Retainers are
often custom made to a customer’s
requirements
• Ball Seats (see figure below) are
available in Light Duty and Heavy Duty

Ball Lock Punches
Here’s how the Ball Lock system works:
15
Ball Lock Punches
A Closer Look:
This “3-point Contact” not only locks the
punch into the retainer but also prevents
the punch from rotating
16
Ball Lock Punches
• Contrary to Popular Belief, The ball does
NOT fully seat in the “teardrop” (ballseat)
• Shaped punches will maintain their correct
orientation by positioning the “teardrop”
(ballseat) in the desired radial position
relative to the shape
17
Ejector Punches
• When the punch face first begins to
penetrate into the metal sheet, a deformation
occurs that creates a small vacuum pocket
between the punch and the eventual slug
• This vacuum pocket in conjunction with any
oil film that might be present can cause the
metal slug to stick to end of the punch and
result in punch edge damage or breakage on
the next stroke
• This is when an ejector punch is helpful
18
Ejector Punches
• An ejector punch contains a “spring loaded”
pin that separates the metal slug from the end of
the punch (see below)
