Abstract:V podjetju GKN Driveline Slovenija prihaja do težav pri izdelavi kletk ležajev za homokinetični zglob, in sicer pri prebijanju okenc na kletki, v katero so vstavljene ležajne kroglice. V podjetju želijo zagotoviti daljšo življenjsko dobo nosilca orodja za prebijanje in so se odločili v prvi fazi preiskati ali je uporabljen predpisani material in/ali je toplotno obdelan kot predvideva tehniška dokumentacija. Naloga zajema pregled prelomnih površin, kemijsko analizo, preiskavo mikrostrukture in merjenje trdote. Vse preiskave so privedle do ugotovitve, da sta material in toplotna obdelava materiala v skladu s tehniško dokumentacijo. Rešitev je potrebno zato poiskati bodisi v drugem materialu, drugačni obdelavi ali v spremembi konstrukcije nosilca.

Title:Metallographic examination of punch holder
Abstract:In GKN Driveline Slovenia there are problems in the production off the bearing-ball separators for the ball bearing in the homokinetic joint. The main problem is connected to punching of holes into which the bearing-balls are inserted. The service time of the punch holder should be extend. In the first phase, it should be examined whether the material and the heat treatment correspond to the technical specification. The task includes the chemical analysis, examination of fracture surfaces and microstructure and hardness measurement. All investigations have led to the conclusion that the material and its heat treatment comply with the technical documentation. Therefore, the choice of another material, a different heat treatment or redesigning of the punch holder should be considered.
Keywords:GKN, Punch holder, Metallographic examination, hardness measurement
