ARRANGEMENT OF THE PUNCH TOOLS
IN GENERAL
The big punch bearing surface and the
removable front block have been constructed in
manner to allow a very wide range punch works:
Through the optionally obtained tools, the
big holes in any form up to the diameter / quadrate
as it is indicated in the capacity table can be
produced. In addition, machining at overhanging
position, with the removed front in addition, during
machining at overhang, with the removed front
block, the of U profiles of double T supports having
diameters or eventually diagonals up to 38mm
highest capacity can be punched.
The punching stamp is held though a
holding ring, according to the size of the stamp
(punch) one or two of the delivered adapters can be
used. The matrixes are fixed to the tensioning plate
through a positioning screw. When the filled punch
stamps and matrixes are be arranged, it should be
paid attention to the screw is correctly placed on
the machined surface of the matrix. In order to allow
a suitable play area and to ensure that the material
is taken out, the punch stamp scraper plate should
be correctly adjusted, however it should not effect
the stamp course. Attention should be paid to that
the lower course limiting switch has been adjusted
as per the instructions. When the holes are punched
with sufficient material, a flat contact occurs at both
sides of the scraper plate. The scraper forces can
be important and unbalanced scraper forces can
lead to the break of the punch stamp through the
contact with a side of the scraper.
No material should be punched which is
thicker than the stamp diameter. The quality of the
hole is a direct finger appearance on the situation of
the punch stamp and matrix.
When the scraper fingers are used for very
big holes or irregular forms, the fingers should be
equally position and adjusted in order to prevent and
unbalanced scraper load.
Additional tools at this multi purpose work
station allow bar and sheet metal bending works,
edge threading, tube threading, tube threading and
general column positioning works.
