Kwimibhobho edityanisiweyo yobude obuphezulu (ERW umbhobho wentsimbi), ukubonakaliswa kokuqhekeka kubandakanya ukuqhekeka okude, ukuqhekeka kwexesha lendawo kunye nokuqhekeka okungaqhelekanga. Kwakhona kukho imibhobho yentsimbi engenazo iintanda phezu komhlaba emva kwe-welding, kodwa ukuqhekeka kuya kubonakala emva kokunciphisa, ukulungiswa okanye ukuvavanywa koxinzelelo lwamanzi.

Oonobangela bokuqhekeka

1. Umgangatho ophantsi wemathiriyeli ekrwada

Kwimveliso yemibhobho edityanisiweyo, ngokuqhelekileyo kukho i-burrs enkulu kunye neengxaki ezigqithisileyo zobubanzi bezinto eziluhlaza.
Ukuba i-burr ingaphandle ngexesha lenkqubo ye-welding, kulula ukuvelisa i-cracks eqhubekayo kunye nexesha elide.
Ububanzi bezinto eziluhlaza bukhulu kakhulu, i-roll hole ye-squeeze igcwele kakhulu, yenza i-peach shape ene-welded, iimpawu ze-welding zangaphandle zinkulu, i-welding yangaphakathi incinci okanye ayikho, kwaye iya kuqhekeka emva kokulungiswa.

2. Umda wekona edibeneyo karhulumente

Imeko yoxhulumaniso lwekona yomda wetyhubhu engenanto yinto eqhelekileyo kwimveliso yeebhubhu ezidibeneyo. Incinci i-diameter yepayipi, inzima ngakumbi ikhonkco lekona.
Ulungelelwaniso lokubumba olungafanelekanga luyimfuneko kumalungu ekona.
Uyilo olungafanelekanga lwe-squeeze roller pass, i-fillet yangaphandle enkulu kunye ne-angle yokuphakama kwe-roller yoxinzelelo zizinto eziphambili ezichaphazela i-angle joint.
Iradiyasi enye ayikwazi ukuphelisa iingxaki ezidibeneyo zekona ezibangelwa kukubumba okungalunganga. Yandisa amandla okucudisa, kungenjalo i-roller yokucudisa iya kuguga kwaye ibe yi-elliptical kwinqanaba lamva lemveliso, eliya kwandisa imeko ye-welding ebukhali kwaye ibangele uqhagamshelo lwekona enzulu.

Umdibaniso wekona uya kubangela ukuba ininzi yentsimbi iphume kwicala eliphezulu, yenze inkqubo yokunyibilika engazinzanga. Ngeli xesha, kuya kubakho i-metal splashing, i-welding seam iya kutshiswa, kwaye i-burrs yangaphandle iya kutshisa, ingaqhelekanga, inkulu kwaye ingabi lula ukuyikhupha. Ukuba isantya se-welding asilawulwa ngokufanelekileyo, "i-welding yobuxoki" ye-weld iya kwenzeka ngokuqinisekileyo.

I-angle yangaphandle ye-squeeze roller inkulu, ukwenzela ukuba i-tube engenanto ingagcwaliswa ngokupheleleyo kwi-roller yokucudisa, kwaye imeko yoqhagamshelwano lomda itshintsha ukusuka kwi-parallel ukuya kwi-"V" imilo, kwaye isiganeko sokuba i-welding seam yangaphakathi ayidibanisi ibonakala. .

I-squeeze roller igqitywe ixesha elide, kwaye i-base bearing igugile. I-shafts ezimbini zenza i-engile yokuphakama, okubangela ukungonelanga amandla okucudisa, i-ellipse ethe nkqo kunye nokuzibandakanya kwe-engile enzima.

3. Ukukhetha okungenangqiqo kwiiparamitha zenkqubo

Inkqubo parameters of high-frequency welded welded imveliso ibandakanya isantya welding (isantya seyunithi), iqondo lobushushu welding (high-frequency power), welding current (high-frequency frequency), extrusion force (designing tool and material), ukuvula i-angle (ukusila) ) yesixhobo Ukuyila kunye nezinto eziphathekayo, indawo yekhoyili ye-induction), i-inductor (impahla ye-coil, i-winding direction, isikhundla) kunye nobukhulu kunye nendawo yokuchasana.

(1) I-frequency ephezulu (ezinzile kwaye eqhubekayo) amandla, isantya se-welding, i-welding extrusion force kunye ne-angle yokuvula zezona zibalulekileyo iiparameters zenkqubo, ezimele zihambelane ngokufanelekileyo, ngaphandle koko umgangatho we-welding uya kuchaphazeleka.

① Ukuba isantya siphezulu kakhulu okanye siphantsi kakhulu, siya kubangela ubushushu obuphantsi be-welding impermeability kunye nobushushu obuphezulu bokushisa, kwaye i-weld iya kuqhekeka emva kokuba ifakwe.

②Xa amandla okucudisa anganelanga, intsimbi edibeneyo yokudibanisa ayinakunyanzeliswa ngokupheleleyo, ukungcola okusele kwi-weld akukhutshelwanga lula, kwaye amandla ayancipha.

Xa i-extrusion force ikhulu kakhulu, i-angle ye-metal flow flow iyanda, i-residu ikhutshwe ngokulula, indawo echaphazelekayo yokushisa iba yincinci, kwaye umgangatho we-welding uphuculwe. Nangona kunjalo, ukuba uxinzelelo luphezulu kakhulu, luya kubangela iintlantsi ezinkulu kunye ne-splashes, okubangela ukuba i-oxide etyhidiweyo kunye nenxalenye yomgangatho weplastiki yesinyithi ikhutshwe, kwaye i-weld iya kuba ncinane emva kokukrwelwa, ngaloo ndlela inciphisa amandla e-weld.
I-extrusion force efanelekileyo iyimfuneko ebalulekileyo yokuqinisekisa umgangatho we-welding.

③I-engile yokuvula inkulu kakhulu, enciphisa isiphumo sokusondela kwe-frequency ephezulu, yonyusa ilahleko yangoku ye-eddi, kwaye inciphisa ubushushu be-welding. Ukuba i-welding ngesantya sokuqala, iintanda ziya kuvela;

Ukuba i-angle yokuvula incinci kakhulu, i-welding current iya kungazinzi, kwaye ukuqhuma okuncinci (intuitively i-dicharge phenomenon) kunye nokuqhekeka kuya kwenzeka kwindawo yokucima.

(2) I-inductor (i-coil) iyona nxalenye ephambili ye-welding inxalenye yombhobho odibeneyo we-high-frequency welded. Umsantsa phakathi kwayo kunye netyhubhu engenanto kunye nobubanzi bokuvulwa kunempembelelo enkulu kumgangatho we-welding.

① Umsantsa phakathi kwe-inductor kunye netyhubhu engenanto inkulu kakhulu, okubangela ukuhla okubukhali ekusebenzeni kakuhle kwe-inductor;
Ukuba i-gap phakathi kwe-inductor kunye ne-tube blank incinci kakhulu, kulula ukuvelisa ukukhutshwa kombane phakathi kwe-inductor kunye ne-tube engenanto, ebangela ukuqhekeka kwe-welding, kwaye kulula ukuba yonakaliswe yi-tube engenanto.

② Ukuba ububanzi bokuvula i-inductor bukhulu kakhulu, kuya kunciphisa ukushisa kwe-welding ye-butt edge ye-tube engenanto. Ukuba isantya se-welding sikhawuleza, i-welding yobuxoki kunye nokuqhekeka kunokwenzeka ukuba kwenzeke emva kokulungiswa.

Ekuveliseni imibhobho ye-welded high-frequency, kukho izinto ezininzi ezibangela ukuqhekeka kwe-weld, kunye neendlela zokukhusela zikwahluke. Kukho izinto ezininzi eziguquguqukayo kwinkqubo ye-welding high-frequency, kwaye naziphi na iziphene zekhonkco ekugqibeleni ziya kuchaphazela umgangatho we-welding.
