Abstract

Zadaća strojeva za štancanje je pomoću alata, silom pritiska, štancati različite oblike plašteva za kutije i slične nepravilne oblike, koje nije moguće masovno oblikovati i proizvesti na brzorezaču, krugorezaču ili trorezaču. Štancanje se obavlja pomoću alata za štancanje – štance, koja djeluje na posebnu, najčešće ravnu temeljnu ploču. Izbacivač izbacuje izradak iz temeljne ploče. Ovaj postupak može biti automatiziran ili se kod štanci starijeg tipa obavlja ručno. Štancanjem se na različite načine mogu obraditi papir, karton i ljepenka. Tim se postupkom izrezuju posebni, složeni oblici, obavlja se perforiranje, utiskivanje i sl. Alati za štancanje mogu biti ravni ili oblikovani noževi te različite vrste kalupa.

U ovom radu će se istražiti razlike u konstrukciji i princip rada dva stroja za štancanje:

- automatska štanca s paralelnim pomakom alata, sistem s automatskim optrgavanjem

- zaklopna štanca.

Istražit će se za koju vrstu proizvoda je koji stroj isplativiji. Tržište trenutno ima veliku potrebu za proizvodima koji se realiziraju na ovakvim strojevima. Očekuje se i povećana potrebe za ambalažom, tako da će ovo praktično istraživanje strojeva različitih konstruktivnih rješenja dati doprinos većoj raspoloživosti ovog doradnog procesa.

Abstract (english)

The die-cutter uses tools and pressure to cut various forms of covers for boxes and similar unusual shapes, which cannot be designed and mass produced on a high-speed cutter, rotary cutter or three-knife trimmer. The cutting is done with a die-cutting tool applied to a special, mostly flat cutting plate (table). The release rubber ejects the cutting from the cutting plate. This process can be automatic or, as in older cutters, manual. Paper, cardboard and pasteboard can be thus treated in various ways. In this way special complicated shapes are made, perforated, embossed, etc. Cutters may be straight or bent knives and various sorts of templates.

This paper will explore the differences in the construction and working principles of two cutting machines:

- automatic platen die-cutter with automatic stripping

- vertical die-cutter.

It will be examined which machine is more profitable for what kind of product. There is currently a great need on the market for products made with these machines. Also, there will be an increased need for packaging, so that this practical analysis of various construction solutions can only contribute to a higher availability of this finishing process.
