IF<br />

Forza di serraggio<br />

La forza esercitata da una pinza IF dipende da molteplici<br />

fattori.<br />

Principalmente il diametro dell'oggetto, ma anche la sua<br />

finitura superficiale, il coefficiente di attrito e la pressione<br />

di alimentazione.<br />

I grafici mostrano la forza di sfilamento (F) di un carico<br />

preso con la pinza a <strong>espansione</strong>, in funzione del diametro<br />

(d).<br />

Per le misurazioni sono stati usati anelli di alluminio, con<br />

rugosità Ra=0.8 e le pinze alimentate a 6 bar.<br />

Le linee nere si riferiscono alle pinze in EPDM e quelle<br />

rosse alle pinze in Silicone.<br />

Gripping force<br />

The force output of an IF gripper depends on several<br />

variables.<br />

Basically on the diameter of the picked object, but also on<br />

the surface finishing, the friction and the air pressure.<br />

The graphs show the extraction force (F) on the gripped<br />

object as a function of its diameter (d).<br />

Aluminum rings, with roughness Ra=0.8 have been used<br />

for the measurements and the grippers supplied with 6<br />

bar compressed air.<br />

The black lines refer to the grippers in EPDM, the red ones<br />

to the grippers in Silicone.<br />
