Difference Handling
 The measured value compared to the template created a
difference
 Difference can be spread out to each bend
 6mm spread out to 7 bends for an 8 sided pole
 The measured difference can also produce an alarm
alerting that the plate differs from template.
 Wrong Plate?
 Adjustable tolerance for what is an acceptable difference
can be made it the control system.

27. Description of Semi Automated bending sequence in Ursviken
Pole Bending Machine.
The trap can be loaded either from the front side or the entrance
side of the machine. The choice is depending on the layout of the
workshop and the types of traps to be processed. Normally large ½
shells, Tri or Quad shells are loaded from the front.
Notes: With heavier plates, we recommend loading from the front to
avoid extensive wear on the top surface of the lower tool.
The front and back gauges are equipped with distance measuring
feedback systems which can measure the width of the trap before
bending and the deflection of the first half when formed.
When the trap is located in press in the processing position the
sequence is as follows:

28. Bending of the first half of the trap.
- The width of the plate is measured and the bending lines are corrected if
needed.
- The front gauges positions the plate and the press beam starts the
bending process.
- The Press can be equipped with a laser measuring system located from
above so that the first bend is verified and compensated for spring back.
The upcoming bends are automatically compensated in the program
- If the press is not equipped with a laser measuring system the gauges
can measure the geometry of trap after bending and indicate to the
operator what the actual result of the bend is. If within tolerance the
machine cycle can be continued, if out of tolerance the program can be
automatically be adjusted to compensate for the upcoming bend angles.
- This procedure continues for all bend within the first half

29. Bending of the second half of the trap.
The partially formed trap is now pushed towards the back gauges and pushed past the
first bend line on the opposite side.
- The back gauge moves forward until the front measuring probes come in contact with
the formed side of the plate, the front gauges also stay enabled as this next
measuring cycle occurs. The trap will now be measured from four points and the
result is compared to the theoretical geometry.
- The front gauge now move to the pre-calculated position plus ~30 mm outside the
theoretical position (just to allow space).
- The rear gauges starts to position the plate to the theoretical value +/- the correction
measured in previous sequences.
- The front gauges moves forward and measures the actual position of the plate and
moves thereafter the corresponding distance so the plate is pinched between the
front and back gauge.
- Normally the plate is positioned correctly at this stage, but if necessary the plate can
be “manually” displaced to make a final correction. This correction is then kept for the
rest of the program. This is could necessary when the formed trap is deflecting on its
own weight commonly know with 3/16” material.
- The bending cycle will now continue and the rear gauges will position the trap
accordingly for the remaining bends.
