Abstract

Ovaj rad opisuje konstruiranje stroja za izradu drva za ogrjev za kućnu upotrebu koji se sastoji primarno od mehaničkih komponenti, a pokretan je jednofaznim elektromotorom. Ideja ovog elektromehaničkog uređaja je minimizirati fizički angažman korisnika tijekom procesa korištenjem specifičnih mehanizama koji samostalno ciklički provode proces dok je elektromotor uključen. Na početku rada prikazan je detaljan pregled uređaja za preradu trupaca u ogrjevno drvo (cjepanice) koji su dostupni na tržištu te isto tako i pregled uređaja iz kućne radinosti. Na temelju pregleda tržišta te mehanizama i komponenti korištenih u postojećim uređajima, ilustrirano je i objašnjeno 5 različitih koncepata. Nadalje se provela evaluacija koncepata, nakon koje je, primarno temeljem zahtjeva za čim manji izvor snage te jednostavnije komponente, odabran jedan koncept za daljnju razradu. Temeljem tako odabranog koncepta, uređaj je konstruiran te je kreiran i 3D model u SolidWorksu. Naposlijetku, proces je ilustriran i objašnjen uz pomoć slika CAD modela u različitim fazama procesa izrade drva za ogrjev te su na kraju prikazani i tehnički crteži pojedinih sklopova uređaja.

Abstract (english)

This paper describes the design of a machine for preparing firewood for domestic use that consists of primarily mechanical components and is driven by a single-phase electric motor. The idea of this electromechanical device is to minimize the user’s physical involvement during the process by using specific mechanisms which carry out the process cyclically while the electric motor is turned on. At the beginning of the paper, a detailed overview of devices for processing logs into firewood available on the market is presented, as well as an overview of home-made devices. Based on the review of the market and mechanisms and components used in existing devices, 5 different concepts are illustrated and explained. Furthermore, an evaluation of the concepts was carried out, after which, mainly based on the requirements for the smallest power source and simpler components, one concept was selected for further development. Based on the chosen concept, the device was designed and a 3D model was created in SolidWorks. Finally, the process is illustrated and explained with the help of CAD model images in different stages of the firewood production process and at the end, technical drawings of individual device assemblies are presented.
