No workpiece preparation

CLUFIX-STUD Tôle Perçage Lamage
Drilling and counterboring can be carried out to embed the head of the insert perfectly flush to the surface (these two stages can be achieved simultaneously using a stepped drill).

CLUFIX-STUD Tôle Poinçonnage
Stepped punching can be carried out to embed the head of the insert perfectly flush to the surface.

These four processes can be used to create the hole destined to receive the CLUFIX-STUD™. Quality of preparation is, however, of overriding importance in guaranteeing optimal crimping which will result in high mechanical resistance. Use of a precision-sharpened punch is, for example, recommended - in order to limit strain-hardening of the hole.

Installation tools

CLUFIX-STUD™ should be fitted using LA CLUSIENNE-CLUFIX oleopneumatic crimping tools. Use of a standard tooling matching the selected CLUFIX-STUD™ diameter is imperative to carrying out installation.

CLUFIX-STUD™ installation settings

In order to guarantee optimum CLUFIX-STUD™ crimping, two key parameters must be taken into consideration:


CLUFIX-STUD Stroke Adjustment

CLUFIX-STUD Stroke S
Ls : refer to data sheet

1. Stroke adjustment
This adjustment optimises crimping quality in line with the chosen CLUFIX-STUD™ part number and the thickness of the workpiece.
The crimping stroke S is calculated using the formula: S = X – Ep
X = variable data for each CLUFIX-STUD™ part number (available from the data sheet in question)
Ep = customer application workpiece thickness
After calculation of S, we recommend that you carry out a crimping test (using your chosen installation tool) on a metal sheet sample matching the thickness used in your application.
This test will also help you check the S (stroke) data by means of the difference between the Lc measurement before crimping and Lts after installation.

Tolerance for Ls data:
Ø M 2.5 M 3 M 4 M 5 M 6 M 8 M 10 M 12 M 14 M 16
+/- 0.3 0.4 0.4 0.4 0.4 0.6 0.6 0.6 0.8 0.8

CLUFIX-STUD Air Pressure Gauge

2. Air pressure
This parameter concerns only oleopneumatic tools.
The air supply pressure level determines the setting force of the installation tool.
To guarantee optimum crimping, we advise you to use an air pressure gauge (positioned upstream of the tooling) linked to the air pressure supply network.
The minimum pressure required is 6 bars. This value corresponds to the usual pressure of an air pressure supply network.
