Core Puller
The use of a core puller expands the
variety of concrete masonry units which can be produced on a concrete
products machine. Many of the complex concrete masonry unit designs
which are popular today feature horizontal openings that have been
formed by a core puller.
The horizontal openings can be in
various shapes. The number of shapes that can be made with the core
puller are virtually limitless.
Products made possible by using a core
puller:
- cored brick,
fabricated on edge with a wormed face, bark face or thumbprint face
- any type of concrete
unit with fake mortar grooves
- various retaining
wall units with bottom key
- protrusion in water
and erosion control block
A core puller is a concrete products
machine attachment. It is comprised of a drawer which is activated by
either hydraulic or pneumatic cylinders to which the tools (forming core
or "forks") required to form the horizontal cores are
attached. The forming forks are usually mounted on spring or rubber pads
in order to minimize transmission of vibration to the core puller
mechanism.
A core puller is installed in front of
the mold on the concrete products machine, above the front delivery
conveyor (green block conveyor). It can be wheel-mounted or leg-mounted.
Depending on available space, wheel-mounted models offer easy roll-away
to facilitate maintenance on the concrete products machine. The
leg-mounted model requires less floor space, however, maneuverability is
not as easy.
Core pullers are available in different
sizes and strokes, and can be engineered to fit any pallet size and
concrete products machine on the market. Designed with double solenoid
valves and simple circuitry, this mechanism requires little maintenance.
