Moeller Manufacturing Company introduces a new patented
mechanical stripper design called the True-Strip. The
True-Strip is a precision-machined, self-contained, die spring
activated device that is compact and fits directly onto
industrial standard retainers.
The basic design features what we call a flanged steel
“can” that is precision machined and burnished from
pre-hardened steel which is black-oxided for corrosion
resistance. A bronze stripper plunger is inserted through a
precision hole in the front part of the can. The plunger has
an I.D. that matches the hole piercing punch with clearance
and provides the stripping action. The plungers are available
in standard lengths for flat piercing operations and an
extended length version that allows for stripper contouring. A
significant design feature is the fact that the stripper is
guided not only by the land of the steel can, but also by the
head on the stripper. This feature creates a dual guiding
condition. Behind the plunger is a steel mechanical die
spring, which provides the stripping force. The spring is
pre-loaded 5% and retained by a threaded retaining cap that
screws in and bottoms out in its mating pocket to compress the
spring to its pre-loaded state. The retaining cap accurately
locates the entire assembly and allows disassembly with a
simple hex wrench. True-Strip can be mounted up to a 15-degree
angle for mechanical cam applications, resulting in a 30%
improvement over other devices.
True-Strip is currently available in seven inch and
metric, heavy duty ball-lock shank diameters. CAD data and
solid models are available above. Custom designs available
upon request, including multi-hole, light-duty and shoulder
type punch configurations.
