Individual operations
- Produce first hole with the help of the length and depth stop.
- Place positioning stop (1) in a vertical position/vertically.
- Adjust the setting dimension (= value displayed on the position indicator – item 2) as shown in fig. 10 or fig. 11.
ATTENTION: The setting dimension is not equal to the hole spacing!
- Secure threaded spindle (6) against accidental changes in position with the help of the clamping lever (7).
- Mount the workpiece with the hole that has just been punched from the top "over the cylinder pin (8), diameter = 6 mm, of the extension".
First, Fit the workpiece flush against the depth stop. Then, set the workpiece lightly against the cylinder pin (8).
ATTENTION: If the pressure on the cylinder pin is too high, this will result in a change in dimensions.
- Actuate the cylinder of the bow punch. During the punching process, the workpiece slides down at the cylinder pin.
- Use the same procedure and the just punched cutout for each subsequent hole.
Correction of dimension displayed on position indicator
If you notice a difference between the nominal dimension and the actual dimension, you can correct it yourself as follows:
- Become familiar with the use of the positioning stop (chapter 5.3).
- Determine the exact difference in measurements (test punching and measurement)
- Loosen "clamp screw of position indicator" (9) from threaded spindle by one turn
- Turn sleeve of position indicator (10), where the clamp screw (9) sits, until the value displayed on the position indicator (2)
corresponds to the actual value.
- Screw "clamp screw of position indicator" (9) back onto threaded spindle.
Latching function of the positioning stop
The stop has 3 latching positions:
Latching position 1:
Latching positions 2 + 3:
When in horizontal position, the latching force must be large enough to keep the stop in place during punching.
The latching force can be adjusted as follows:
- Loosen lock nut (11)
- Turn out spring-loaded thrust piece (12) a little to obtain a stronger latching force
- Tighten lock nut (11)
