CONSTRUCTION OF 5t WORKSHOP HYDRAULIC PRESS

U uvodnom dijelu ovog rada opisane su preše, njihova namjena, podjela i način rada. Naziv ovog rada su hidraulične preše što znači da je ostatak rada baziran na hidrauličnim prešama. Princip rada hidraulične preše zasniva se na Pascalovom zakonu koji je objašnjen u radu. Navedene su prednosti i nedostatci ovih preša te je provedena analiza tržišta za iste preše. Opisane su i konstrukcijske izvedbe (C, ZS, H) preša. U točki konstrukcija preše navedeni su svi potrebni dijelovi za izradu hidraulične preše te su posebno opisani dijelovi hidraulične dizalice. Postupak izrade preše sastoji se od pet koraka koji su detaljno opisani u ovoj točki. Isto tako opisan je princip rada te su navedeni svi vijčani spojevi i opisana uloga opruge na ovoj preši. U proračunu osnovnih elemenata proveden je proračun vijaka na odrez te proračun poprečnih greda na savijanje. Utvrđeno je da svaki vijak može podnijeti opterećenje na koje je izložen. Tehnička dokumentacija sastoji se od sedam crteža, šest radioničkih i jednog sastavnog koji se nalaze u prilogu rada. Zadnja točka ovog rada je zaključak u kojem je ukratko opisan cijeli rad te napravljen osvrt na ključne cjeline.In this bachelor thesis introduction describes the presses, their purpose, classification and mode of operation. As the title said the rest of the work will be based on hydraulic presses. A hydraulic press works on the principle of Pascal's law which was explained later on. The advantages and disadvantages of these presses are stated and market analysis was performed for the same presses. The design versions (C,ZS,H) of the presses are also described. In section “press construction“ all the necesary parts for the production of a hydraulic press are listed and the parts of the hydraulic crane are described in particular. The process of making a press consists of five steps which are described in detail in this part. Mode of operation is portrayed, all bolted joints are listed and the role of the spring on press is also explained. In section “calculation of basis elements“ the calculation of cut screws and the calculation of transverse beams for bending were performed. It has been determined that each screw can endure the load to which it is exposed. The technical documentation consists of seven drawings (six workshop drawings and one component drawing) that are attached. In conclusion a brief description of this bachelor thesis is given and review of key units is made
