Each cycle considers the following steps:
In between step 1 and step 6 the parameters such as force and speed change several times.
One cycle takes about 2 seconds, depending on the materials and the stack-up.
|One-sides access||Dismantling||Clamp force||Pull-out strength||Combination
of different materials
|Without pilot hole|
|Resistance spot welding|
|Automotive – Car body & enclosure|
|White goods, i.e. fridges|
Disadvantages linked to pneumatically operated feed stroke mechanism:
=> Extensive efforts related to parameter settings.
=> Risk for fails if screw and/or layer thicknesses change (tolerances).
The earliest possible and automated recognition of penetration, regardless of tolerances, is the basis of an ideal thread forming process.
The system automatically adjusts to actual conditions. Efforts related to parameter settings reduce to a minimum.
The EC-Servo drive ensures full control on feed stroke speed and feed stroke force at any time.
Processes related to funnel and thread forming can be optimized.
DEPRAG EC-Servo Screwdriving system with built in transducers for torque and feed stroke force.

Individually configured process screen
ADAPTIVE: The automated recognition of thresholds regardless of tolerances on fastener and product and the subsequent automated adjustment of parameters ensure the ideal joining sequence.
