Yiziphi izici ze umshini wokufudumeza ophakeme kakhulu

Amaphrofayili namapuleti asetshenziswa kakhulu ezakhiweni zensimbi, kuyilapho ama-H-imishayo engamaphrofayili asetshenziswa kakhulu. I-I-beam nensimbi yesiteshi esetshenziswa kakhulu esikhathini esidlule kancane kancane kwathathelwa indawo yi-H-beam ngenxa yokuthi amapharamitha wesigaba ayengenangqondo kwezinye izikhathi. Kulo mongo, imishini yokushisela i-high-frequency welding isetshenziswa kabanzi. Ngakho-ke, yiziphi izici zomshini wokushisela imvamisa ephezulu?

1. Izigaba zomnotho neziphusile

Insimbi ye-H-section eshiselwe umshini welding we-high-frequency inezakhiwo ezinhle kakhulu zesigaba. Uma kuqhathaniswa nensimbi ye-H-section yensimbi eshisayo, ngaphansi kwesimo esifanayo sesisindo seyunithi, i-coefficient yesigaba sayo kanye nokumelana nokugoba kuphakeme kune-hot-rolled H-section steel. Ebunjiniyela besakhiwo sensimbi, inani lensimbi elisetshenziswa engxenyeni efanayo, insimbi yesigaba se-H egoqwe ngokushisayo likhulu kunelensimbi ye-high-frequency welded we-H-section. Ema-villas anesakhiwo sensimbi, izakhiwo zokuhlala eziphansi neziphansi, uma zisetshenziswe ngokunengqondo, izinzuzo zayo zingasetshenziswa ngokugcwele ukuze kuzuzwe injongo yokonga insimbi nokunciphisa izindleko. Umshini wokushisela we-high-frequency welding osebenza kahle kakhulu unomnotho onengqondo kakhulu we-cross-section.

2. Izinhlobo ezahlukene zokukhiqiza

Umshini wokushisela we-high-frequency welding uncibilikisa izinsimbi zokwakheka okufanayo ndawonye, ​​futhi unezidingo ezixekethile zokwakheka kwezinto eziyisisekelo. Awukwazi nje ukushisela i-carbon steel evamile, kodwa futhi insimbi ye-alloy, insimbi engagqwali, i-Al, i-Cu, i-Ni, i-Ti namanye ama-alloys. Ngoba i-H-beam ekhiqizwa umshini wokushisela we-high-frequency welding ayikhawulelwe kangako yimishini futhi inemininingwane eminingi yomkhiqizo. Ngakho-ke, imishini yokushisela i-high-frequency welding iyathandwa.

3. Isivinini esikhulu nokusetshenziswa okuphansi

Insimbi emise okwe-H eshiselwe umshini wokushisela i-high-frequency welding isebenzisa ngokugcwele umphumela wesikhumba kanye nomphumela oseduze we-high-frequency current, ukuze i-high-frequency current igxile kakhulu endaweni ewumngcingo, kanye nesisekelo. insimbi ingasuswa ezintweni eziyisisekelo ngesikhathi esifushane futhi ngokusetshenziswa okuncane. Ukushisa ekamelweni lokushisa kuya ekushiseni kwe-welding. Insimbi yokushisela emise okwe-H eyimvamisa ephezulu ayidingi intambo yokushisela, i-flux, nokuhlanza indawo, ngakho-ke izindleko zokucubungula ziphansi kakhulu kunalezo zensimbi efakwe emanzini e-arc emise okuka-H.

Insimbi emise okwe-H eshiselwe umshini wokushisela imvamisa ephezulu ingeye-welding yokuxhumana. Insimbi emise okwe-H ene-high-frequency welding inezinzuzo ze-cross-section eyongayo nenengqondo, ukunemba okuphezulu kobukhulu, ukuhlukahluka okuphelele nokucaciswa, isivinini esikhulu, nokusetshenziswa okuphansi. Ngokuthuthuka okuqhubekayo kobuchwepheshe bokukhiqiza, ikhwalithi yomkhiqizo ifinyelelwe. Intuthuko enkulu, futhi inkambu yohlelo lokusebenza iyakhula kancane kancane. Umugqa wokukhiqiza ulungele kakhulu ukutshalwa kwezimali kanye nokwakhiwa kwamabhizinisi amancane naphakathi nendawo.
