ADJUSTMENT AID FOR A JOINING DEVICE HAVING A PUNCH AND A COUNTER-TOOL, AND METHOD FOR ADJUSTING THE JOINING DEVICE

摘要

The present disclosure provides an adjustment aid for a joining device having a punch and a counter-tool which can be oriented coaxially to one another and can be moved axially towards each other for a joining movement relative to one another. Furthermore, the present disclosure provides a method for adjusting a joining device with a punch and counter-tool. A grid marking is embossed in a reshaped test part with the assistance of an embossable grid marking on a punch surface or on a counter surface of the counter-tool. This grid marking is evaluable in comparison to the discernible impressions of the punch surface and counter surface of the counter-tool.
