Stiskalnica za hladno sintranje

MRVAR, GAŠPER (author), Nedeljković, David (mentor)

Diplomsko delo opisuje razvoj in proces izdelave stroja za postopek hladnega sintranja. Sintranje je postopek izdelave končnih posameznih izdelkov iz prahu, s segrevanjem materiala pri temperaturi preko 1000 °C. Hladno sintranje pa temelji na izdelavi keramičnih materialov pri temperaturah, nižjih od 200 °C, vendar po drugačnem postopku. Na podlagi naročila se je izdelal stroj po predhodnih tehničnih specifikacijah in željah kupca. Stiskalnica je avtomatska, ima hidravlični cilinder za enoosno obremenitev ≥ 20 ton in delovno temperaturo v modelu za stiskanje do 300 °C. Model je takšen, da omogoča stiskanje keramičnih prahov v tabletke, dizajn orodja pa primeren za hitro menjavo modela za stiskanje tablet z največjim premerom do 20 milimetrov. Za krmiljenje je uporabljen programirljivi logični krmilnik Mitsubushi FX5U, ki je povezan s temperaturnim regulatorjem Omron EECC-QX3ASM-003 in operaterskim panelom na dotik Kinco MT4434TE, na katerem je možnost nastavljanja tlaka, temperature in časa cikla stiskanja. Največji problem pri izdelavi je bila visoka temperatura pri stiskanju. Zaradi raztezanja materiala med segrevanjem in stiskanjem hkrati je bilo potrebno uporabiti kvalitetne materiale s kvalitetno obdelavo.

• Title: Machine for Cold Sintering Process

Abstract

This diploma thesis describes how the machine for cold sintering process is designed and manufactured. Sintering is the process of manufacturing finished individual products from powder by heating the material at temperatures above 1000 °C. Cold sintering, however, is based on the production of ceramic materials at temperatures below 200 °C, but by a different process. Based on the received order, a machine was made according to the previous technical specifications and demands of the customer. The press is automatic, has a hydraulic cylinder for a uniaxial load of ≥ 20 tonnes and operating temperature in the press model up to 300 °C. The model allows for the compression of ceramic powders into pills, while the tool design is suitable for swiftly changing the tablet compression model with a maximum diameter of up to 20 millimetres. The machine is controlled with a programmable logic controller, the Mitsubushi FX5U, which is connected to the temperature controller Omron EECC-QX3ASM-003 and the Kinco MT4434TE touch panel, which has the ability to adjust the pressure, temperature and compression cycle time. The biggest problem with the manufacturing was the high temperature of the compression. Due to the elongation of the material during heating and compression at the same time, it was necessary to use quality materials with high quality processing.
