MFDC Ikibanza cyo gusudira Ubwiza: Ibintu 7 by'ingenzi & Ubuyobozi bwiza

Mu nganda zigezweho zikora inganda, Hagati - Umuyoboro uhoraho (MFDC)imashini zo gusudirababaye ibikoresho by'ingirakamaro mu binyabiziga, mu kirere, ibikoresho byo mu rugo, no mu nganda za elegitoroniki, bitewe n’imikorere yabyo, gukoresha ingufu nke, hamwe no gusudira bidasanzwe. Ariko, kugirango ukoreshe neza imikorere yabasudira MFDC kandi ugere kubwiza bwizewe, buhoraho bwo gusudira, ababikora bagomba gusobanukirwa byimazeyo no kugenzura neza ibintu byinshi bifitanye isano.

Iyi ngingo isesengura buri gihe ibintu birindwi byingenzi bigira ingaruka nziza kuri MFDC yo gusudira kandi bitanga ingamba zifatika zo gutezimbere.

Ibipimo byo gusudira nibyo byerekana neza uburyo bwo gusudira nugget hamwe nimbaraga zifatanije, bigira uruhare rukomeye muburyo bwiza bwo gusudira MFDC. Igenzura risobanutse kuri ibi bintu bitatu byingenzi nibyo bisabwa kugirango habeho gusudira neza.

1. Welding Current: Imbaraga zo Gutwara Nugget

Imiyoboro yo gusudira niyo soko yambere yubushyuhe, kandi ubunini bwayo bugena neza ingano nubunini bwa nugget. Ikoranabuhanga rya MFDC, binyuze murwego rwo hejuru - inversion (mubisanzwe 1kHz kugeza 4kHz), itanga amashanyarazi ataziguye, igabanya neza ihindagurika ryubu hamwe nubushuhe butaringaniye bukunze kugaragara muri Welding Current (AC).

• Ubunini bwa none nubunini bwa Nugget: Umuyoboro udahagije uganisha ku kwegeranya ubushyuhe budahagije, bikaviramo gusudira gukonje cyangwa gusudira imbeho ntoya cyane, ikananirwa kubahiriza imbaraga zisabwa. Ibinyuranye, umuvuduko ukabije utera ubushyuhe ako kanya, bigatera kwirukanwa, bidasesagura ibintu gusa ahubwo binanduza electrode kandi bigabanya imbaraga zo gusudira.
• Ibyerekeranye bifatika bifatika: Ubucucike buriho bugomba guhuzwa neza nibikoresho bisudwa. Kurugero, ibyifuzo byubucucike buringaniye kuri - ibyuma bya karubone ni 8-10 A / mm²; ku byuma bidafite ingese, kubera kwihanganira kwinshi, birakenewe cyane ubucucike buri hagati ya 12-14 A / mm².

2. Igihe cyo gusudira: Ubuhanzi bwa Millisecond yubuhanga

Igihe cyo gusudira nigihe cyo kwegeranya ubushyuhe. Inyungu nyamukuru yabasudira MFDC nubushobozi bwabo bwo kugera mugihe gito cyane cyo gusudira, kikaba ari ingenzi cyane mu gusudira ibikoresho bitwara neza cyangwa bisize.

• Inzitizi ninyungu zicyuma cya Galvanised: Iyo gusudira ibyuma bya galvanis, icyuma cya zinc (gushonga hafi . 419 dogere) kiri munsi yicyuma (gushonga hafi . 1500 dogere). Igihe kinini cyo gusudira kirashobora kuganisha kuri zinc vaporisation, kwanduza electrode, no gukomera. Isudira rya MFDC rishobora kugenzura igihe cyo gusudira mugihe gito cyane (urugero, milisegonda 15-30), bigatuma nugget yihuta mbere yuko umwuka wa zinc uhinduka, bityo bikazamura ubwiza bwa weld hamwe nubuzima bwa electrode.
• Igenzura ryinshi: {0

3. Imbaraga za Electrode: Guhindura plastike no guhagarara kwa Nugget

Imikorere yingufu za electrode (cyangwa umuvuduko wa electrode) nugukora ibishoboka byose kugirango uhuze hagati yakazi mbere yo gusudira no gutanga imbaraga zihagije zo guhindura ibintu mugihe cyo guhagarika nugget no guhagarika kwirukana.

• Imbaraga nke nimbaraga nyinshi: Imbaraga zidahagije ziganisha ku guhura kwinshi, kwibanda ku bushyuhe hejuru, byoroshye kwirukana no gutwikwa hejuru. Imbaraga zikabije, ariko, zirashobora kurenga - gukanda nugget yashongeshejwe, bigatuma isenyuka, igabanya imbaraga zayo, kandi ishobora kugabanya ubucucike buriho.
• Ubuyobozi bufatika: Ifumbire mvaruganda ikoreshwa kenshi muruganda nkaho itangirira: Imbaraga za Electrode (Newtons) Th Ubunini bwibintu (mm) × 50. Urugero, iyo gusudira icyuma cya 2mm cyibyuma, imbaraga zambere zishobora gushyirwaho hafi 100N.

Ndetse hamwe nogushiraho neza gusudira, ibikoresho byuburyo hamwe no kubungabunga urwego rwo gusudira ahantu bigira ingaruka itaziguye ihererekanyabubasha ryimyuka no gukwirakwiza neza ubushyuhe.

1. Ubuyobozi bwa Electrode no gucunga imyambarire

Electrode ni itumanaho ryogukwirakwiza no gukoreshwa, kandi imiterere yacyo ningirakamaro mu gusudira ubuziranenge. Electrode isanzwe ikozwe muri Chromium Zirconium Umuringa (Cu - Cr - Zr).

• Kwanduza no Kurwanya: Mugihe cyo gusudira, isura ya electrode irashobora okiside cyangwa ikanduzwa bitewe nubushyuhe bwinshi hamwe no gufatira ibintu (cyane cyane zinc iva mubyuma bya galvanis), bigatuma abantu barushaho guhangana, kugabanya ubukana bwubu, bityo rero, ingaruka ku bunini bwa nugget.
• Imyambarire iteganijwe: Gahunda yo kwambara ya electrode iteganijwe igomba gushyirwa mubikorwa hashingiwe ku bwinshi bw'umusaruro. Intego yo kwambara ni ukugarura umwimerere wa diametre yumwimerere nuburyo bwa electrode, ukareba ko uburinganire buriho. Abasudira ba kijyambere akenshi bafite ibikoresho byo kwambara byikora kugirango byemeze neza nigihe gikwiye.

2. Gukonjesha Sisitemu

Uburyo bwo gusudira butanga ubushyuhe bwinshi, kandi sisitemu yo gukonjesha neza ni urufunguzo rwo gukomeza imikorere ya electrode na transformateur.

• Ingaruka zo gushyuha cyane: Gukonja bidahagije bituma ubushyuhe bwa electrode bwiyongera, kwihuta koroshya no kwambara, mugihe nanone bigabanya ubushobozi bwibikoresho, bigatuma habaho gutakaza ubushobozi bwo gusudira.
• Gukurikirana no Kubungabunga: Igipimo cy’amazi akonje, umuvuduko, nigitutu bigomba gukurikiranwa buri gihe. Ubushyuhe bwamazi bugomba kugenzurwa mubipimo bya dogere 20 kugeza kuri 30. Icyarimwe, guhinduranya ubushyuhe bigomba guhorana isuku kugirango ubushyuhe bwiza bugabanuke.

• Ikibazo cyurwego rwo hejuru - Imbaraga zicyuma (AHSS): Ikoreshwa cyane munganda zitwara ibinyabiziga, AHSS (nkicyuma cya DP nicyuma cya TRIP) ifite imbaraga nyinshi, ariko idirishya ryayo ryo gusudira (urutonde rwibipimo byemewe) muri rusange ni rito ugereranije nicyuma gike -. Gusudira AHSS bisaba imbaraga nimbaraga nyinshi, kandi haribisabwa cyane kugirango igipimo gikonje nyuma yo gusudira kugirango hirindwe imiterere ya martensite yoroheje, akenshi bisaba ko hiyongeraho ubushyuhe kugirango wongere ubukana bwa weld.
• Imiterere yubuso: Ibihumanya hejuru yakazi, nka okiside, amavuta, hamwe ningese, byongera cyane kurwanya imikoranire, bikabuza gutembera neza, kandi bigatera gukwirakwiza ubushyuhe butaringaniye, bigatuma gusudira gukonje cyangwa kwirukanwa bishoboka cyane. Kubwibyo, gusukura no gutesha agaciro mbere yo gusudira nintambwe zikenewe kugirango tugere kubisubizo bihoraho.

2. Guhuza Ibidukikije nuburyo bukoreshwa

• Kugenzura Ibidukikije: Ubushyuhe bwinshi mumahugurwa yumusaruro byongera umutwaro kuri sisitemu yo gukonjesha. Ubushuhe bwinshi burashobora gushikana kumurongo hejuru yakazi, ugahindura imikoranire. Kubungabunga imikorere ihamye mubijyanye nubushyuhe nubushuhe nikintu kitaziguye ariko cyingenzi kugirango ibikorwa bihamye.
• Ibipimo ngenderwaho: Gushyira mu bikorwa uburyo bukoreshwa (SOPs) ni ngombwa mu gukuraho impinduka z’abantu. Amahugurwa yumwuga kubakoresha ni ngombwa kugirango barebe ko bakurikiza byimazeyo ibyangombwa byo gushyiraho ibipimo, gukora imyambarire, no kubungabunga. Byongeye kandi, igenamigambi ryiza kuri buri porogaramu rigomba kwandikwa neza kandi rikabikwa, bigakora sisitemu yo gucunga neza.

Umwanzuro

Imashini - Imashini yo gusudira ya Frequency Directeur Igikoresho cyo gusudira ni igikoresho gikomeye cyo kugera ku ntera yo hejuru -, ariko imikorere yayo ishingiye ku kugenzura byimazeyo kandi kuri gahunda yo gusudira, ibikoresho, ibikoresho, hamwe n’ibidukikije bikora. Ukoresheje milisegonda - kugenzura neza urwego rutangwa nikoranabuhanga rya MFDC, rifatanije nubuyobozi bwa electrode bunonosoye hamwe no guhuza neza n’ibikoresho byihariye nka AHSS n’ibyuma bya galvanis, abayikora ntibashobora gusa kongera umusaruro ushimishije ahubwo banakomeza kubahiriza ubuziranenge bw’isoko ryiza, bityo bagakomeza umwanya wambere ku isoko ryapiganwa.
