Sheet Metal Punching |
 |
|
|
At Stevens Rowsell we operate a Trumpf Trupunch 2020 with full automation.
Punching in terms of making holes
or cutting out pieces of sheet
metal is done by a process known
as shearing. Shearing is the result
of placing a sheet between an
upper tool (punch) and a lower
tool (die). As the sheet is moved
around the machine table the upper
tool punches through it producing
a hole with the same shape as
the geometric contour of the punch
tool.
The
positioning, movement and processing
of the sheet is synchronised by
a CNC program written using special
software by an engineer.
Aside from punching openings,
our machines can also be used
for creating contours by a process
called ‘nibbling’ or
can be used to create special
shapes by a process called ‘forming’.
 The punching station uses an electro-hydraulic punching head for consistently high punching power and has a rotatable single tool adapter for lowering the number of tools needed and decreasing the machine and tooling set up times. With the appropriate tooling the punching head also allows for a wide range of forms to be produced such as extrusions, louvers, beads, flanges and hinges.
Hydraulic clamping ensures that an exact and centric allocation of punch and die is applied.
The machine is support by an integrated and compact sheet handling system for automated loading and unloading of sheets 2500 x 1250mm
We have a two function multi tools which consist of several single tools combined in one holder. This considerably increases the number of tools available.
Our punch has a tapping function which allows us to form threads in mild steel, stainless steel and aluminium without producing chippings.
