Used Eccentric Presses for sale with Fixed Stroke and Adjustable
Stroke, with or without Air Clutches are important machine tools used in
the Engineering, Sheet Metal, Construction & Mining
Industries across South Africa, Botswana, DRC, Kenya, Namibia,
Mozambique, Malawi, Zimbabwe, Zambia, and other countries in Africa.
An eccentric press is a specialized
machine for shaping and forming sheet metal components. It features a unique
eccentric shaft with an offset center that converts rotary motion into precise
linear reciprocating motion. This motion drives a slide or ram with tooling
like dies and punches, applying immense force to the metal workpiece. Eccentric
presses accurately stamp, punch, blank, and bend metal, making them necessary
in manufacturing, engineering, and construction industries.
Eccentric Presses shape metal components across diverse
industries, excelling in automotive manufacturing for stamping body panels and
brackets with high force and precise strokes. A primary application is
automotive manufacturing, where they stamp body panels, brackets, and sheet
metal parts. Consumer goods rely on these presses for punching lids, forming
housings, and consistent metalworking. Hardware production utilizes their
punching, bending and forming capabilities for hinges, brackets and fasteners.
An Adjustable Stroke Eccentric Press allows operators to
precisely control the ram's downward stroke length, accommodating varying
workpiece thicknesses needing to change tooling setups. This adjustability
enables manufacturers to leverage these presses for efficiently processing
different part profiles within single production runs, minimizing setup times
and maximizing productivity. The ability to adjust stroke length offers
flexibility in metalworking operations while maintaining consistent quality.
Eccentric Presses with an Air Clutch utilize compressed air
to engage and disengage the clutch mechanism. This provides smooth, consistent
power transmission from the motor to the eccentric shaft. The air clutch allows
easy start/stop control of the press stroke for enhanced operator safety. Its
low inertia design enables rapid cycle times and quick changeovers between
production runs
Some Eccentric Presses feature a cushion mechanism that
decelerates the ram's downward motion near the end of the stroke. This cushion
helps absorb the impact
forces, reducing shock and vibrations. The controlled deceleration protects the
tooling and press components from excessive wear and damage. Eccentric Presses
with cushions are ideal for delicate or high-precision forming operations on thinner
material
Eccentric presses offer versatility for pressing various
materials. Common options include metals like aluminium, steel, and brass for
forming, stamping, and shaping components. Copper, titanium, and various alloys
respond well to the controlled pressure distribution eccentric press machines
provide. Iron components benefit from the precise stroke control, while zinc
and lead can be formed with minimal material waste. The eccentric mechanism
allows for specialised metal forming operations where conventional hydraulic
presses might lack the necessary accuracy and production speed.
