Uyikhetha njani imathiriyeli yokunxibelelana rhoqo yokuwelda?

 Zimbini iintlobo eziphambili ze-welding ye-induction ephezulu, ukuqhagamshela kunye nokudibanisa i-induction. Ukufakelwa kwe-welding yindlela yokudibanisa engaqhagamshelani usebenzisa iikhoyili. Ukuqhagamshelana ne-welding kukusetyenziswa kwezinto ezihamba phambili ukukhokelela ngokuthe ngqo kwi-high-frequency current kwindawo ye-welding yeepayipi zensimbi, kwaye emva koko udibanisa izinto emva kokufudumeza.

Imeko yesicelo semathiriyeli yokunxibelelana ne-high-frequency welding

Imeko yokusebenza yentloko yokuqhagamshela entlokweni ephezulu inzima kakhulu, ngakumbi ngolu hlobo lulandelayo:

1) amanzi, i-emulsion, ubushushu obuphezulu, ubushushu, umsi, igesi etshabalalisayo okanye ulwelo kunokubonwa ngamehlo ahamba ze kwiindawo ezininzi;

I-2) Ukuthwala ii-AC zangoku kunye nevolthi, ukuhamba rhoqo okuqhelekileyo kungama-200 kHz-800 kHz, kwaye okwangoku kuyahluka ukusuka kumakhulu aliqela ukuya kumawakawaka ama-amperes ngokwamandla ezixhobo;

3) Kwimveliso, abafowunelwa kwezixhobo basebenza phantsi koxinzelelo oluthile, ngokubanzi ukusuka kwi-2 ukuya kwi-4 bar;

4) Izixhobo ziqhubeka ngokuqhubekayo emgceni, kwaye umfowunelwa uhlala ethwele ukukhuhlana kwezinto ezi-welding ezingezantsi phantsi koxinzelelo;

5) Ngenxa yokuba indawo apho unxibelelwano ibekwe khona imdaka, kwaye i-oxide eveliswe kwinkqubo yobushushu obuphezulu bomfowunelwa ishushu kakhulu, ubumdaka be-oxide buya kutsha kunye ne-arc ezotywe phantsi kwentshukumo yangoku;

6) Xa into edityaniswe apha ngezantsi ingalingani, ukuxhathisa koqhakamshelwano kulomfowunelwa kuya kutshintsha kakhulu, kwaye iintlantsi zombane zedigri ezahlukeneyo ziya kuvela kunxibelelwano;

Ukongeza kwezi meko zendalo zingasentla, indawo yokusebenza yokunxibelelana nge-welding iya kuba ngumceli mngeni omkhulu ngenxa yokucinezelwa koqhagamshelo olusebenzayo lwabasebenza emasimini, ukomelela kwezinto ezidityanisiweyo, ubulukhuni bezinto ezidityanisiweyo, amandla okukhuhla umphezulu kunye njalo njalo.

Izinto ezifunwayo kwiimpawu zokunxibelelana ngewelding frequency

   Ngenxa yeemfuno zokusebenza koqhakamshelwano lokudibanisa uqhagamshelo kunye nokusikelwa umda kokusingqongileyo kwentloko ye-welding, iimfuno ezizodwa zempawu zibekwa phambili kwizinto zentloko yokuqhagamshela kwentloko. Njengentloko ye-welding, izixhobo zayo kufuneka zisebenze ngokuhambelana nokusetyenziswa kwezi zinto zilandelayo:

I-1) ukuqhuba, kuba umnxibelelwano uphethe iimfuno zokuthwala ezikhoyo ngoku, izixhobo zonxibelelwano kufuneka zibe nokuqhuba okuphezulu ukunciphisa ukumelana noqhakamshelwano, ukukhutshwa okuphantsi okuphantsi kunye nokukhupha ukukhanya ukunciphisa i-arc yangoku kunye nexesha le-arc, ke izinto kufuneka zibe nokuqhuba okuphezulu;

2) Ubuchule bokuqhuba ubushushu, kuba umnxibelelwano uphethe inkulu ngoku, ubushushu bayo buphezulu, ngenxa yoko kufuneka ubuchule bokutshabalalisa ubushushu kunye nokukwazi ukuqhuba ubushushu obuphezulu ukuze ubushushu obuveliswe yi-arc okanye iJoule umthombo wobushushu ungadluliselwa kwisiseko soqhakamshelwano ngokukhawuleza;

3) Amandla, kuba umnxibelelwano usebenza phantsi koxinzelelo oluthile, kuyafuneka ukuba uqwalasele ukomelela kwemathiriyeli;

I-4) Nxiba ukumelana, kuba umnxibelelwano uhlala uthambisa umphezulu wento e-welding ngexesha lomsebenzi, izinto zonxibelelwano kufuneka zibenomxhesho omkhulu wokunxiba;

5) Ukuqina yenye yeempawu ekufuneka ziqwalaselwe. Phantsi koxinzelelo zoqhakamshelwano, ubunzima obuncinci bunokunyusa indawo yoqhakamshelwano, ukunciphisa ukumelana koqhakamshelwano, kunye nokunciphisa imeko yokufudumeza koqhakamshelwano kunye nokuqiniswa okungashukumiyo ngexesha lokudibana. Ukuqina okuphezulu kunokunciphisa indawo ye-welding kunye nokuphucula ukunganyangeki koomatshini;

Ungazikhetha njani izinto zonxibelelwano?

Ukukhethwa kwezinto zonxibelelwano ikakhulu kuxhomekeke kwiindleko, iimfuno zomhlaba, imveliso yewelding ubungakanani bendawo kunye neempawu zemveliso.

1. ubhedu olungenayo ioksijini ngokubanzi okanye ubhedu obungenawo ioksijini obungenamksi buyamkelwa xa ukhetha kwizinto ngokubanzi, kunye nokuqhutywa kobhedu kufikelela kuma-99%;

2. Khetha ingxubevange yobhedu, efana ne-tungsten-copper alloy, chromium copper, tungsten carbide alloy copper, njl .;

3. Ezinye iialloys, ezinjengee alloys ze titanium; Ukukhetha izinto ze-alloy, umxholo othile wobhedu kunye nomxholo we-alloy kufuneka ugqitywe ngokungqinelana nesicelo sentsimi, kuthathelwa ingqalelo ukuqhuba, ukunxiba ukumelana, iimfuno zomhlaba, njl.

Umxholo wenqaku uvela kwezinye iindawoKukho iintlobo ezimbini eziphambili zentsimbi ye-induction ephezulu, iwelding yokunxibelelana kunye nokufakwa kwe-induction. Ukufakelwa kwe-welding yindlela yokunxibelelana nokudibanisa usebenzisa iikhoyili. Ukuqhagamshelana ne-welding kukusetyenziswa kwezinto ezihamba phambili ukukhokelela ngokuthe ngqo kwi-high-frequency current kwindawo ye-welding yeepayipi zensimbi, kwaye emva koko udibanisa izinto emva kokufudumeza.

Imeko 5.Application ophezulu-rhoqo iwelding izinto zoqhagamshelwano

Indawo yokusebenza ye-high-frequency contact welding inzima kakhulu, ngokukodwa ngolu hlobo lulandelayo:

7. amanzi, i-emulsion, iqondo lobushushu eliphezulu, ubushushu, umsi, irhasi yentsimbi okanye ulwelo unokubonwa ngamehlo ahamba ze kwiindawo ezininzi;

8. Ukuthwala amandla ombane aphezulu e-AC okwangoku kunye nevolthi, ukuhamba rhoqo okuqhelekileyo kungama-200 kHz-800 kHz, kwaye okwangoku kuyahluka ukusuka kumakhulu aliqela ama-amperes ukuya kumawaka aliwaka ama-amperes ngokwamandla ezixhobo;

9. Kwimveliso, abafowunelwa kwezixhobo basebenza phantsi koxinzelelo oluthile, ngokubanzi ukusuka kwi-2 ukuya kwi-4 bar;

10. Izixhobo ziqhubeka ngokuqhubekayo emgceni, kwaye umnxeba uhlala ethwele ukukhuhlana kwezinto ezi-welding ezingezantsi phantsi koxinzelelo;

11.Ngokuba okusingqongileyo apho umfowunelwa khona kumdaka, kwaye i-oxide eveliswe kwinkqubo yobushushu obuphezulu bomfowunelwa ishushu kakhulu, ukungcola kwe-oxide kuya kutsha kunye ne-arc ityhilwe phantsi kwentshukumo yangoku;

12. Xa into edityaniswe apha ngezantsi ingalingani, ukuxhathisa koqhakamshelwano kuya kutshintsha kakhulu, kwaye iintlantsi zombane ezahlukileyo ziya kuvela kunxibelelwano;

Ukongeza kwezi meko zendalo zingasentla, indawo yokusebenza yokunxibelelana nge-welding iya kuba ngumceli mngeni omkhulu ngenxa yokucinezelwa koqhagamshelo olusebenzayo lwabasebenza emasimini, ukomelela kwezinto ezidityanisiweyo, ubulukhuni bezinto ezidityanisiweyo, amandla okukhuhla umphezulu kunye njalo njalo.
