Indlela umfutho womoya othinta ngayo ingxenye yokusika

Umfutho womoya ungenye yemingcele ebalulekile ethinta ikhwalithi yokusika (ikakhulukazi ikhwalithi yezingxenye zokusika). Umthelela wawo awuyona "inzuzo ephezulu" eyodwa noma "inzuzo ephansi", kodwa "ububanzi obuhle kakhulu" obudinga ukuhambisana kahle nemingcele efana nesivinini sokusika, amandla/ugesi, njll. ". Ngokuvamile,Ithonya lomfutho womoya engxenyeni yokusika libonakala kakhulu esimweni se-slag yokulenga, ubulukhuni bengxenye, ububanzi bomqhekezo kanye nomphetho ongezansi.Amacala amabili alandelayo okufanele achazwe ngokuningiliziwe:

1. Ukusika nge-laser (insimbi yokusika esizwa umoya-mpilo njengesibonelo)

Ekusikeni nge-laser, indima eyinhloko yegesi (njenge-oxygen, i-nitrogen) yile:

• Ukushisa okusizayo (i-oxygen):Ukusabela kwe-exothermic ngensimbi, okwandisa amandla.
• Ukususa i-slag:Ukususa izinto ezincibilikisiwe esikhaleni ukuze kube nokusika okuhlanzekile.
• Vikela ilensi nomzimba wesibhamu:vimbela ukuchaphazeka ekulimazeni izingxenye ze-optical.

Imiphumela yomfutho womoya ophansi:

• Ingxenye enzima, i-slag elengayo inzima: lokhu ukusebenza okuqondile kakhulu. Umfutho womoya onganele awukwazi ukuqeda insimbi encibilikisiwe kahle nangesikhathi. Lezi zinsimbi ezincibilikisiwe zizonamathela phansi kwepuleti, zenze i-slag (burr) okunzima ukuyisusa. Ngesikhathi esifanayo, insimbi encibilikisiwe engenakupheshulwa izophinde iqine, yenze ingxenye yokusika ibe nzima, ingasheleli, futhi yakhe imivimbo.
• Ukwehla kwesivinini sokusika: Ukuze kuqedwe i-slag, kungadingeka ukunciphisa isivinini sokusika, ngaphandle kwalokho ngeke kukwazi ukusika futhi kuthinte ukusebenza kahle kokukhiqiza.
• Kungase kungadabuli: ezimweni ezimbi kakhulu, umfutho womoya uphansi kakhulu ukuba ungavunguza ungqimba oluncibilikisiwe, okwenza ukusika kuphazanyiswe.

Imiphumela yomfutho womoya ophezulu:

• Ingxenye evundlile ibangela ukuzungeza kanye nokwanda kobulukhuni: umfutho wegesi ophezulu kakhulu uzokwakha ukugeleza okuguquguqukayo endaweni yokugeleza kwe-laminar okuzinzile. Lokhu kuzulazula kuzophazamisa ukugeleza okuvamile kwensimbi encibilikisiwe, kanye nokwakheka kokuzungeza okuvamile ohlangothini lokusikwa, ukuze ingxenye ibukeke “iqhakaza kakhulu”, kodwa inciphise ukushelela.
• I-kerf iyanwebeka: Igesi enomfutho ophezulu ilingana "nokuqhuma" ukugxila kwe-laser, okuholela ekutheni izingxenye eziphezulu nezingezansi ze-kerf zibe zibanzi kunokuvamile, futhi ukunemba kuyancipha.
• Iphansi lokusikwa lishiswe kakhulu noma limise okwesikwele: igesi enomfutho ophezulu izoletha ukushisa okukhulu phansi kwepuleti, okuholela ekushisweni ngokweqile kwezinto ezingezansi, kwakha unqenqema olukhulu olungezansi (ngisho namakhona ayindilinga), kanti ukusikwa kuveza ukuma kwesikwele okunengxenye ebanzi nengxenye ephansi encane, esikhundleni sengxenye eqondile.
• Igesi elahliwe, khulisa izindleko: umfutho ophezulu ongadingekile uzokhulisa ngqo izindleko zokusetshenziswa kwegesi.

Umfutho womoya ongcono kakhulu:

• Kudingeka ihlelwe ngokuphelele ngokwezinto ezibonakalayo, ukujiya, isivinini sokusika kanye nokusebenza kahle kwepuleti nge-laser.
• Kumapuleti aqinile, umfutho womoya ophezulu uvame ukudingeka ukuqinisekisa ukuthi kunamandla anele okususa i-slag phansi.
• Uma kusetshenziswa umoya-mpilo, ukubekwa kwengcindezi yomoya nakho kudinga ukucabangela ukuhambisana kokusabela komlilo.

2. Ukusikwa kwe-plasma

• Ekusikeni kwe-plasma, igesi (namanzi) yiyona ndlela ekhiqiza i-plasma arc, futhi yiwona amandla aphephula izinto ezincibilikisiwe futhi avimbele i-arc.

Imiphumela yomfutho womoya ophansi:

• I-arc ayizinzile futhi kulula ukuyiphula: ingcindezi ayanele ukwakha i-arc ye-plasma eqinile negxilile.
• Amandla okusika ancishisiwe futhi ukusika akukwazi ukunqunywa: amandla kanye nesivinini se-plasma akwanele ukuncibilikisa nokususa izinto ngempumelelo, ikakhulukazi lapho kunqunywa amapuleti amakhulu.
• Ukulenga i-slag okungathi sína: njengokusika nge-laser, i-slag ayikwazi ukususwa ngempumelelo, okuholela ekwandeni kokulenga i-slag phansi.
• Ukusikwa “kugobile”: ukusikwa kuzoba ngesimo se-V esinohlangothi olubanzi kanye nephansi elincane, ngoba i-arc ayinawo amandla anele phansi ukusika iqonde phezulu.

Imiphumela yomfutho womoya ophezulu:

• I-arc "iyavunguza" futhi amandla awagxilile: umfutho wegesi ophezulu kakhulu uzovunguza i-arc ye-plasma ehlukene kakhulu, okuholela ekwehleni kobuningi bamandla. Nakuba ijubane lokuhamba komoya lishesha kakhulu, amandla okusika angase anciphe, ikakhulukazi kuma-plate amakhulu.
• Ukwanda kokuguguleka kwe-electrode kanye ne-nozzle: Umfutho ophezulu usho ukuqina okuphezulu kokusebenza, okunciphisa kakhulu impilo yokusebenza kwezingxenye ezigqokwayo (ama-electrode, ama-nozzle).
• Ingxenye ephezulu yesinqunyiwe iyancibilika, yakhe "umlomo wensimbi": i-arc ehlukanisiwe izoncibilikisa kakhulu ingxenye ephezulu yesinqunyiwe, yakhe isinqunyiwe esinomfanekiso ongu-V oguquliwe esinohlangothi olubanzi kanye nengxenye engezansi encane, okuyisici esivamile sokusika kwe-plasma ngomfutho womoya owedlulele.
• Ingxenye elukhuni: i-arc engazinzile izoholela emiseleni ejulile kanye nokubola kwengxenye esikiwe.

Umfutho womoya ongcono kakhulu:

• Amapharamitha anconywe ngumkhiqizi wokunikezwa kwamandla e-plasma wokunikezwa kwamandla athile, ukuvulwa kwe-nozzle kanye nohlobo lweshidi/ukujiya kumele alandelwe ngokuqinile. Ukunqunywa kwe-plasma ezidingweni zokufanisa ingcindezi kuqinile kakhulu.

Ithebula Lokuqhathanisa Elifingqiwe

Iziphetho Nezincomo

1. Akukho nzuzo yendawo yonke:Inani elifanele lokucindezela lincike enkambisweni ethile yokusika (i-laser/plasma), uhlobo lwezinto, ukujiya, isivinini sokusika kanye neminye imingcele yenqubo.

2. Nquma ngokusika kwesilingo:Indlela ethembeke kakhulu ukuzama ukusika. Ngaphansi kwamandla nesivinini esinqunyiwe, lungisa ingcindezi yomoya, bheka ushintsho lwesigaba sokusika, bese uthola inani lengcindezi yomoya eline-slag encane kakhulu, isigaba esibushelelezi kakhulu kanye nokuma okuhle kakhulu komthungo wokusika.

3. Naka ukufana okuphelele:Umfutho womoya kumele uhambisane eduze nesivinini sokusika. Ukwandisa isivinini ngokuvamile kudinga ukwanda okufanayo komfutho womoya ukuqinisekisa ukuthi i-slag iyapheshulwa ngesikhathi.

4. Qinisekisa ikhwalithi yomthombo wegesi:Ngaphezu kwengcindezi, ubumsulwa nokoma kwegesi nakho kubaluleke kakhulu, ikakhulukazi ekusikeni nge-laser kanye nokusika nge-plasma kwezinto ezibonisa kakhulu.

Ngakho-ke, uma ikhwalithi yesigaba esisikiwe itholakala iphansi, umfutho womoya ungenye yemingcele ebalulekile okudingeka ihlolwe futhi ilungiswe kuqala.
