Icyapa cy'icyuma cya 12L14: ikimenyetso cy'icyuma gikata neza kandi gikozwe mu buryo bworoshye
Mu rwego rw'inganda zigezweho, imikorere y'icyuma igira ingaruka zitaziguye ku bwiza n'umusaruro w'ibicuruzwa. Nk'icyuma gikozwe mu buryo bw'ikoranabuhanga gikata neza, icyuma cya 12L14 cyabaye amahitamo meza ku mashini zikora neza, ibice by'imodoka, ibikoresho by'ikoranabuhanga n'izindi nganda zifite imiterere yihariye y'ibinyabutabire n'imiterere myiza yo gutunganya.
1. Imiterere y'ibinyabutabire: ingenzi mu mikorere myiza
Imikorere yihariye ya plate y'icyuma ya 12L14 ituruka ku miterere yayo ya shimi yakozwe neza. Ingano ya karuboni igenzurwa neza kuri ≤0.15%, ibi bikaba byemeza gukomera no kudahinduka kw'ibikoresho; ingano nyinshi ya manganese (0.85 - 1.15%) yongera imbaraga no kudashira; naho ingano ya silikoni ni ≤0.10%, ibi bigabanya ingaruka mbi ku mikorere. Byongeye kandi, kongeramo fosifore (0.04 - 0.09%) na sulfur (0.26 - 0.35%) birushaho kunoza imikorere yo gukata; kongeramo icyuma cya lisansi (0.15 - 0.35%) birushaho kugabanya imikorere yo gukata, bigatuma uduce tworoshye kuvunika, kandi bikongera imikorere myiza yo gutunganya no gukoresha ibikoresho.
II. Ibyiza by'imikorere: kwita ku gutunganya no gushyira mu bikorwa
1. Umusaruro mwiza wo gukata: Icyuma cya 12L14 gishobora kwitwa "umufatanyabikorwa mwiza mu gutunganya imashini". Ubudahangarwa bwacyo bwo gukata buri munsi ya 30% ugereranije n'ubw'icyuma gisanzwe. Gishobora gukata vuba cyane no gutunganya ibiryo byinshi. Gikora neza ku byuma byikora, ibikoresho bya CNC n'ibindi bikoresho, bigabanya cyane ukwezi kw'itunganya no kugabanya ikiguzi cyo gukora.
2. Ubwiza bw'ubuso: Irangi ry'ubuso bw'icyuma cyatunganyijwe cya 12L14 rishobora kugera kuri Ra0.8-1.6μm. Nta buryo bugoye bwo gutunganya nyuma bukenewe. Gutera amashanyarazi, gutera imiti n'izindi nzira zo gutunganya ubuso bishobora gukorwa mu buryo butaziguye, ibyo bikaba bidatuma gusa umusaruro ugaragara, ahubwo binatuma umusaruro urushaho kuba mwiza.
3. Imiterere ihamye ya mekanike: Ingufu zo gukurura icyuma ziri hagati ya 380-460MPa, uburebure bwacyo ni 20-40%, uburebure bwacyo ni 35-60%, kandi ubukana bwacyo buri hagati ya 35-60% (hot-rolled state 121HB, cold-rolled state 163HB). Ishobora kugumana imiterere ihamye ya mekanike mu bihe bitandukanye by'akazi no guhaza ibyifuzo by'ikoreshwa ry'ibintu bitandukanye.
4. Kurengera ibidukikije n'umutekano: Icyapa cy'icyuma cya 12L14 gikurikiza amabwiriza mpuzamahanga yo kurengera ibidukikije, cyatsinze icyemezo cy'ibidukikije cya EU SGS n'icyemezo cy'ibidukikije cyo mu Busuwisi, ntigikubiyemo ibintu byangiza nka lisansi na mercure, kandi gihuye n'iterambere ry'inganda zigezweho zikora ibikomoka ku bidukikije.
III. Ibisobanuro n'amahame: Hindura ibikenewe byinshi
Isahani y'icyuma ya 12L14 ifite uburyo bwinshi bwo kuyikoresha mu bipimo. Ubunini bw'isahani y'icyuma ishyushye ni 1-180mm, ubunini bw'isahani y'icyuma ishyushye ni 0.1-4.0mm, ubugari busanzwe ni 1220mm, n'uburebure ni 2440mm, ishobora guhindurwa mu buryo bworoshye hakurikijwe ibyo abakiriya bakeneye. Ku bijyanye n'amahame ngenderwaho, ihuye n'amahame mpuzamahanga nka AISI 12L14 muri Leta Zunze Ubumwe za Amerika, SUM24L muri JIS G4804 mu Buyapani, na 10SPb20 (1.0722) muri DIN EN 10087 mu Budage, bigamije ko ibicuruzwa bihinduka kandi bihinduranya ku isoko mpuzamahanga.
IV. Amashami akoreshwa: Guteza imbere iterambere ry'inganda
1. Gukora imodoka: bikoreshwa mu gukora ibice bigezweho nk'imigozi y'ibikoresho bya gearbox, aho bashyira lisansi, aho bashyira sensor, nibindi, kugira ngo sisitemu z'amashanyarazi n'uburyo bwo kugenzura imodoka zikoresha ikoranabuhanga bikore neza.
2. Ibikoresho by'ikoranabuhanga n'ibikoresho by'ikoranabuhanga: Ni byo bikunzwe cyane mu gukora ibikoresho by'ikoranabuhanga bigezweho nka ibikoresho by'isaha, ibikoresho byo kubaga by'ubuvuzi, n'ibisuguti byo guhindura ibikoresho by'ikoranabuhanga, bifasha ibikoresho by'ikoranabuhanga n'ibikoresho by'ikoranabuhanga kugera ku buryo bworoshye kandi bunoze.
3. Gukora imashini: Bigira uruhare runini mu gukora ibice nk'imirongo y'amashanyarazi, ibikoresho bifasha mu gutwara ibintu, n'udupira duhuza ibikoresho byikora, kandi binoza ituze n'ubudahangarwa bw'ibikoresho bikoresha imashini.
4. Ibikoresho by'ingenzi bya buri munsi n'ibicuruzwa bikoreshwa: Bikoreshwa cyane mu bikoresho byo mu nzu bigezweho, ingufuri, imigozi mito n'ibindi bicuruzwa, hashingiwe ku mikorere n'ubwiza.
Nk'icyuma cyiza cyane gihuza imikorere myiza, gutunganya byoroshye, no kurengera ibidukikije, icyuma cya 12L14 kirimo gutuma inganda zigezweho zikora ibintu bigezweho zigana ku musaruro mwiza, ubwiza, n'ibidukikije hamwe n'ibyiza byacyo bidasanzwe, kandi cyabaye inkingi ikomeye ku nganda nyinshi kugira ngo zigere ku iterambere ry'ikoranabuhanga no guhanga udushya mu bicuruzwa.
