Precision Punch positioning precision from the recognition is essential since it
is the recognition from the punch of moving parts within the CNC system
underneath the charge of the movement is capable of the precision, so by
calculating the career precision of statistical precision punch can determine
the punch Following the automatic operation is capable of the very best work
surface machining precision. It should be emphasized here the current
positioning precision from the test is really a rapid, positioning measurement,
for many feed system stiffness may not be good CNC punch, using different feed
speed positioning, can get different positioning precision.
In addition,
the career precision from the recognition results and also the ambient
temperature and also the axis from the running condition, the majority of
today's CNC punch press with the semi-closed-loop system, position recognition
components are mainly set up in the drive motor, the ball screw thermal
elongation hasn't yet effective From the identification measures. Therefore,
it's not surprising that, once the positioning precision is measured, you'll be
able to generate a mistake of .01 to .02 mm inside a 1-m stroke following a
rapid round-trip. It is because the screw rapidly moves several occasions, the
top temperature may rise .5 ~ 1 ¡æ, so the thermal growth of the screw caused.
The thermal elongation from the error, some punch uses pre-stretching (preload)
approach to lessen the impact. ???????The repeatable positioning precision of
every axis is easily the most fundamental precision index from the axis, which
reflects the soundness from the movement precision from the axis, the precision
from the punch is generally can't ensure the stability of production. Nowadays,
because of the growing quantity of CNC system functions, systematic error for
example pitch accumulation error and backlash error could be paid for each
coordinate motion precision, only random error cannot be compensated, and
repeated positioning precision reflects Towards the drive mechanism from the
integrated random error, it's no method to make use of the CNC compensation
system to fix, when it's discovered of tolerance, just the feed chain to
fine-tune correction. Therefore, purchasing punch presses should give priority
to select and repeat our prime positioning precision from the punch.
Precision punching in using different rubber stamping occasions with
various rubber stamping die, if employed for stretching the occasion will have
to make use of the drawing die, and drawing die includes a more special needs,
using punch processing needed processing The fabric should have an empty holder
and also the method is ejected. Once the stretch processing to become a lot of
tension is needed towards the bottom from the punch mold to set up a buffer
device to accomplish pressure side and the top action, which buffer device
within the press market is known as mold pad.
At present, the mold pad
utilized in the stretching occasion is essentially the oil mold pad, however the
mold pad includes a very significant shortcomings punch trump game, mainly in three aspects:
1, because of the utilization of oil pressure, its parts manufacturing precision
needs are relatively high, leading to relatively expensive 2, using relatively
expensive, because of the existing rubber stamping equipment generally use
pneumatic clutch brake, the factory only gas source, using existing mold pad
needs a separate group of hydraulic booster equipment 3, the hydraulic seal
needs are relatively high, the prospect of oil leakage is comparatively large,
dirty work atmosphere man
punches kangaroo in the face.
To essentially solve this issue,
precision machinery for producing precision punch press design, producing a
pneumatic die pad device, rather of utilizing oil hydraulic oil, with no
separate source, can share the gas source using the punch, with manufacturing
Cost punch
3d home design, not oil, fast response, easy maintenance, the benefits of
clean work atmosphere.
