•
Anti-clockwise to reduce H
•
One step between two pin holes on the end stop (A8) is about 0.12 mm
•
Re-tighten the blocking screw (A31) without excessive torque
It should be observed that this H value is valid when the work head works without
sheet material. When material to be clinched is present, the elasticity of the machine
will result in a higher residual bottom thickness, the St value, on the joint than the
theoretical one
Finding the optimum setting
The adjustment of the H value may be sufficient for producing an acceptable joint,
with a St value close to the value given in tables from chapter “Tooling selection and
joint optimization".
In case the required St value is not obtained, the end stop must be adjusted, and a
final adjustment will be made by testing on a sample and measuring the St value, ref.
to Fig .7
•
Install the selected tool kit
•
Set the drive pressure to 6 bar
•
Untighten the blocking screw (A31)
•
lnsert material to be clinched and make a joint, while checking that the air
pressure is well stabilized at 6 bar before releasing the trigger
•
Measure the St value using a pivoting caliper gauge or other appropriate device
•
Adjust, if necessary the end stop (A8) as described in the above section “Setting
the reference value” until the desired St value is produced on the joint
•
To get a greater St value, turn clockwise
•
To reduce the St value, turn anti-clockwise
•
Due to the elasticity, one step between 2 pin holes will be less than 0.12
mm under load
•
Repeat the process until the desired St value is obtained
•
Do not forget to re-tighten the locking screw (A31)
