Existuje mnoho faktor\u016f, kter\u00e9 ovliv\u0148uj\u00ed proces d\u011brov\u00e1n\u00ed d\u011brovac\u00ed stroj<\/a>. Dnes se zam\u011b\u0159\u00edme na tlou\u0161\u0165ku plechu. Tlou\u0161\u0165ka plechu je relativn\u00ed. Obecn\u011b naz\u00fdv\u00e1me plech o tlou\u0161\u0165ce pod 4 mm tenk\u00fd plech a plech o tlou\u0161\u0165ce nad 4 mm.<\/p>\n\n\n\n

Vliv tlou\u0161\u0165ky plechu na proces st\u0159\u00edh\u00e1n\u00ed se projevuje v n\u00e1sleduj\u00edc\u00edch aspektech:<\/p>\n\n\n\n

(1) Tlou\u0161\u0165ka listov\u00e9ho materi\u00e1lu p\u0159\u00edmo ovliv\u0148uje p\u0159im\u011b\u0159enou mezeru matrice.<\/h5>\n\n\n\n

Mal\u00e1 po\u017eadovan\u00e1 v\u016fle p\u0159inese \u0159adu probl\u00e9m\u016f, jako jsou zm\u011bny v p\u0159esnosti matrice. Pro ocel st\u0159edn\u00ed tvrdosti s tlou\u0161\u0165kou plechu 0,2 mm je po\u017eadovan\u00e1 p\u0159im\u011b\u0159en\u00e1 v\u016fle 0,012-0,016 mm (oboustrann\u00e1 v\u016fle).<\/p>\n\n\n\n

(2) Tlou\u0161\u0165ka plechu m\u00e1 kladn\u00fd vztah k d\u011brovac\u00edmu tlaku <\/h5>\n\n\n\n

Kdy\u017e d\u011brov\u00e1n\u00ed<\/a> tenk\u00fdch plech\u016f, je odolnost proti prora\u017een\u00ed men\u0161\u00ed nebo rovna jmenovit\u00e9mu tlaku razn\u00edku. P\u0159i d\u011brov\u00e1n\u00ed siln\u00fdch materi\u00e1l\u016f je situace p\u0159esn\u011b opa\u010dn\u00e1.<\/p>\n\n\n\n

Pokud obsluha d\u011bruje mal\u00e9 otvory do siln\u00e9ho plechu s obecnou strukturou, d\u011brova\u010d se snadno zlom\u00ed. Pro vy\u0159e\u0161en\u00ed zlomen\u00ed razn\u00edku je nutn\u00e9 p\u0159ijmout razn\u00edk s charakteristikami: razn\u00edk je um\u00edst\u011bn mezi vodic\u00edmi pouzdry s velkou pevnost\u00ed a tuhost\u00ed tak, aby byl razn\u00edk chr\u00e1n\u011bn.
