Abstract
U ovom završnom radu prikazana je toplinska obrada probijača izrađenog od alatnog čelika 60WCrV7 koji pripada skupini nisko i srednjeugljičnih W-Cr-(Si)-V čelika za hladni rad. Rad se sastoji od teorijskog i eksperimentalnog dijela. U teorijskom dijelu sažeto je predstavljen povijesni razvoj alatnih čelika i podjela alatnih čelika. Opisana su svojstva, karakteristike i primjena alatnih čelika za hladni rad. Detaljnije je opisan alatni čelik 60WCrV7 te postupci klasične toplinske obrade kojima se obrađuje ovaj čelik. U eksperimentalnom dijelu provedena je toplinska obrada alata i ispitnih uzoraka površinskim kaljenjem u pogonu temeljeno na iskustvenim podacima i u laboratoriju temeljeno na proračunatim i izabranim parametrima za žarenje za redukciju zaostalih naprezanja, kaljenje i niskotemperaturno popuštanje. Nakon toplinske obrade provedeno je mjerenje tvrdoće alata i ispitnih uzoraka te analizirani rezultati.
Abstract (english)
This bachelor thesis deals with the heat treatment of a punch made of the tool steel 60WCrV7, which belongs to the group of cold work W-Cr-(Si)-V tool steels with low and medium carbon content. The work consists of a theoretical and an experimental part. In the theoretical part, the historical development of tool steels and the classification of tool steels are briefly presented. The properties, characteristics and applications of cold work tool steels are described. The tool steel 60WCrV7 is described in more detail, as well as the classical heat treatment processes used to process this steel. In the experimental part, heat treatment of tools and test specimens was carried out by surface hardening in the factory based on empirical values and in the laboratory based on calculated and selected parameters for annealing to relieve residual stresses,hardening and tempering at low temperature. After heat treatment, the hardness of tools and test specimens was measured and the results analyzed.
