Intshayelelo:
Umbhobho we-Quilted ongenamthungo luhlobo lwemathiriyeli yombhobho wentsimbi echanekileyo emva komzobo obandayo okanye ukuqengqeleka okushushu.Ngenxa yokuba akukho maleko oksijini kwiindonga zangaphakathi nangaphandle zombhobho wentsimbi ochanekileyo, [1] phantsi koxinzelelo oluphezulu ngaphandle kokuvuza, ukuchaneka okuphezulu, ukugqiba okuphezulu, ukugoba okubandayo ngaphandle kokuguqulwa, ukuvutha, ukubetheka ngaphandle kokuqhekeka njalo njalo, isetyenziswa ikakhulu. ukwenzela ukuveliswa kwezixhobo ze-pneumatic okanye i-hydraulic, njengeesilinda okanye iisilinda, ezinokuthi zingenamthungo.Ukwakhiwa kweekhemikhali zetyhubhu ekhutshiweyo engenamthungo yicarbon C, isilicon Si, manganese Mn, sulphur S, phosphorus P, chromium Cr.
Umbhobho we-Quilted ongenamthungo wamkela iteknoloji yokucubungula
Umbhobho we-quilted seamless usetyenzwa ngokuqengqeleka.Ngenxa yokuxinezeleka okushiyekileyo kwi-surface layer, kuyanceda ukuvala i-micro cracks ebusweni kunye nokuthintela ukwanda kokhukuliseko.Inokuphucula ukuxhathisa umhlwa kunye nokulibazisa isizukulwana okanye ukwandiswa kweentanda zokudinwa, ukuze kuphuculwe amandla okudinwa kombhobho wentsimbi ekhutshiweyo.Ngokwenza ukuqengqeleka, umaleko obandayo osebenza nzima wenziwa kumphezulu wokuqengqeleka, onciphisa i-elastic kunye ne-deformation yeplastiki yendawo yokunxibelelana yeperi yokusila, ngaloo ndlela kuphuculwe ukuxhathisa kokunxiba kodonga lwangaphakathi lombhobho wentsimbi okhutshiweyo kunye nokuphepha ukutshisa. ebangelwa kukusila.Emva kokuqengqeleka, ukuncitshiswa koburhabaxa bomphezulu kunokuphucula ipropati efanelekileyo.
Rolling machining luhlobo lwetshiphu yasimahla.Kwiqondo lobushushu eliqhelekileyo, i-deformation yeplastiki yentsimbi isetyenziselwa ukuthambisa uburhabaxa obuncinci bomphezulu womsebenzi ukuze kufezekiswe injongo yokutshintsha ubume bomphezulu, iimpawu zoomatshini, imilo kunye nobukhulu.Ngoko ke, le ndlela inokufezekisa iinjongo ezimbini zokupholisa kunye nokomeleza ngexesha elifanayo, elingenako ukwenza ukugaya.
Kungakhathaliseki ukuba luhlobo luni lwendlela yokucubungula esetyenziselwa ukucubungula, kuya kuhlala kukho i-convex efanelekileyo kunye ne-concave amanqaku angalinganiyo kumphezulu weendawo, kunye nesiganeko seendawo eziphakamileyo kunye neentlambo,
Ukuqengqeleka komgaqo wokusetyenzwa: Luhlobo lokugqitywa koxinzelelo, kukusetyenziswa kwesinyithi kwimeko yesiqhelo yobushushu beempawu ezibandayo zeplastiki, ukusetyenziswa kwezixhobo zokuqengqeleka ukwenza uxinzelelo oluthile kumphezulu wokusebenza, ukuze i-workpiece yentsimbi yomphezulu isebenze. qukuqela, ugcwalise kwintsalela esezantsi yeconcave, kwaye ufezekise uburhabaxa bomgangatho wokusebenzela obuncitshisiweyo.Ngenxa yokuguqulwa kweplastiki yesinyithi eqengqelekayo, ukuqina kwezicubu ezingaphezulu kunye nokuncipha kwengqolowa, ukubunjwa kwefiber exineneyo, kunye nokwakheka koxinzelelo olushiyekileyo, ukuqina kunye namandla, ngaloo ndlela kuphuculwe ukuxhathisa ukunxiba, ukuxhathisa umhlwa kunye nokuhambelana kwe-corrosion. umphezulu womsebenzi.Ukuqengqeleka yindlela yokwenza iplastiki ngaphandle kokusika.
Umbhobho okhutshiweyo ongenamthungo iingenelo ezininzi:
1, ukuphucula uburhabaxa bomphezulu, uburhabaxa bungafikelela kwiRa≤0.08µ m okanye njalo.
2, uburharha obuchanekileyo, ubungqimba bunokuba ngaphantsi kwe-0.01mm.
I-3, ukuphucula ubulukhuni bomphezulu, ukuguqulwa kwamandla kupheliswa, ubunzima bokwandisa i-HV≥4 °
I-4, emva kokucubungula i-residual stress layer, phucula amandla okudinwa ngama-30%.
I-5, ukuphucula umgangatho wokufaneleka, ukunciphisa ukunxiba, ukwandisa ubomi benkonzo yamalungu, kodwa iindleko zokucubungula iinxalenye ziyancipha.

35CrMo ingxubevange yentsimbi umbhobho
Iinkcukacha ngemveliso:
Ububanzi bangaphandle bombhobho wensimbi 20-426
Umbhobho wentsimbi ubukhulu bodonga lwe-20-426
Intshayelelo yemveliso:
Ngokomzekelo, i-40Cr.(Umxholo weCarbon we-35CrMo ingxubevange yombhobho wentsimbi yi-0.32 ~ 0.40, i-silicon 0.17~0.37, i-manganese 0.40 ~ 0.70, i-molybdenum 0.15 ~ 0.25, i-chromium 0.80 ~ 1.10)
② Izinto eziphambili zokudibanisa kwintsimbi, ngaphandle kwezinye izinto ezincinci, zibonakaliswa ngokubanzi ngeepesenti ezininzi.Xa umxholo we-alloy ophakathi ungaphantsi kwe-1.5%, kuphela isimboli se-element siphawulwe ngokubanzi kwinombolo yentsimbi, kodwa kungekhona umxholo.Nangona kunjalo, kwiimeko ezikhethekileyo, kulula ukubhidanisa, inombolo "1" inokumakishwa emva kwesimboli sento, njengenombolo yensimbi "12CrMoV" kunye ne "12Cr1MoV", umxholo wechromium yangaphambili ngu-0.4-0.6%, kwaye le yokugqibela yi 0.9-1.2%.Yonke enye into iyafana.Xa i-avareji yesiqulatho se-alloying element ≥1.5%, ≥2.5%, ≥3.5%…… “, isimboli ye-elementi kufuneka imakishwe emva komxholo, ingabonakaliswa njengo-2, 3, 4……… njl. Umzekelo, 18Cr2Ni4WA.
③ Izinto ze-alloy ezifana ne-vanadium V, i-titanium Ti, i-aluminiyam AL, i-boron B kunye nomhlaba onqabileyo we-RE kwintsimbi zizinto ze-microalloying elements.Nangona umxholo uphantsi kakhulu, kufuneka zisaphawulwe kwinombolo yentsimbi.Ngokomzekelo, kwintsimbi ye-20MnVB.I-Vanadium yi-0.07-0.12% kunye ne-boron yi-0.001-0.005%.
④ "A" kufuneka yongezwe ekupheleni kwenombolo yentsimbi yezinga eliphezulu lensimbi ukuze lihluke kwintsimbi yezinga eliphezulu.
⑤ Injongo ekhethekileyo ye-alloy structural iron, i-steel number prefix (okanye isimamva) imele injongo yesimboli yentsimbi.Umzekelo, intsimbi ye-30CrMnSi esetyenziselwa ngokukodwa izikrufu ze-riveting ichazwa njenge-ML30CrMnSi.
Ityhubhu ye-alloy kunye netyhubhu engenamthungo zombini zinobudlelwane kunye nomahluko, azinakubhideka.
Umbhobho we-alloy yipayipi yensimbi ngokuhambelana nezinto zokuvelisa (oko kukuthi, izinto eziphathekayo) ukuchaza, njengoko igama libonisa ukuba lenziwe ngombhobho we-alloy;Kunye umbhobho ingenamthungo yintsimbi umbhobho ngokungqinelana nenkqubo yemveliso (ingenamthungo) ukuchaza, eyahlukileyo umbhobho ingenamthungo yi welded umbhobho, kubandakanywa ngqo umthungo welding umbhobho kunye umbhobho spiral.
Itekhnoloji yokuvelisa:
1. Ukuqengqeleka okushushu (umbhobho wentsimbi ongenamthungo) : ityhubhu engqukuva ingenanto → ukufudumeza → ukugqobhoza → ukuqengqeleka kwediagonal ezintathu eziphezulu, ukuqengqeleka okuqhubekayo okanye ukukhutshwa → ukuhluba → ukulinganisa (okanye ukunciphisa) → ukupholisa → ukulungisa → uvavanyo lwe-hydrostatic (okanye ukuhlolwa) → ukumakisha → ugcino
2. Umbhobho wentsimbi obandayo (uqengqelekiyo) ongenamthungo: ityhubhu engqukuva ingenanto → ukufudumeza → ukugqobhoza → isihloko → ukuqhola → ukuchola → ukufakwa kwe-oyile (iplate yobhedu) → umzobo obandayo ohamba ngeendlela ezininzi (ukuqengqeleka okubandayo) → ityhubhu engenanto → unyango lobushushu → ukulungisa → uvavanyo lwe-hydrostatic (ukuhlolwa) → ukumakisha → ukugcinwa
