Cold Rolled ASTM 42CrMo Q355b 20# 1045
Sharaxaad Gaaban:
Dhuumaha birta ee saxda ah waa nooc ka mid ah walxaha birta ah ee saxda ah ka dib sawir qabow ama duubid kulul.Tuubooyinka birta ah ee saxda ah ayaa inta badan loo isticmaalaa si loo soo saaro alaabada pneumatic ama qaybaha hydraulic, sida dhululubada ama dhululubada saliidda, sababtoo ah faa'iidooyinkooda sida lakabka oksijiinta ee gudaha iyo dibaddaba, ma jirto wax daadinta cadaadiska sare, saxsanaanta sare, dhamaystirka sare. ma jiro qallafsanaan inta lagu jiro qaloocinta qabow, ololaya, fidsan iyo dildilaac la'aan Tuubbada saxda ah ee birta ah waxay leedahay saxnaanta cabbirka sare, dhamaystirka dusha sare ee gudaha iyo dibadda, ma jiro filim oksijiin ah oo ku yaala gudaha gudaha iyo dibadda ee tuubada birta ka dib daaweynta kulaylka, ma jiro dildilaaca balaariyay iyo tuubo bir ah oo fidsan, ma laha qallafsanaan inta lagu jiro qaloocinta qabow, waxayna u adkeysan kartaa cadaadis sare, waxaana loo isticmaali karaa qallafsanaan kala duwan oo qalafsan iyo farsamaynta farsamada qoto dheer.
Tuubooyinka birta ee Haihui ayaa ku takhasusay wax soo saarka caadooyinka tayada sare leh ee tuubooyinka birta ah ee aan toosnayn ee hoos yimaada heerarka caalamiga ah ASTM A519, ASTM A106, ASTM A500, ASME SA500, DIN2391, DIN1629, EN10305-1, DIN17121, EN10297-11,444, JIS34, iyo JIS34Waxaan bixinaa adeeg habaynta dufcadaha yaryar, gaar ahaan shirkadaha yaryar iyo kuwa dhexdhexaadka ah.Maaddada ceeriin, dulqaad gudaha iyo dibadda ah ee dulqaadka iyo joogteynta, qallafsanaanta gudaha iyo dibadda, toosnaanta, sifooyinka farsamada, eccentricity, qaabka gaarka ah, birta daawaha, dhexroor yar oo dhumucdiisuna tahay tuubooyinka birta ah ee aan sinnayn oo dhan waa la habeyn karaa.Qiyaasta wax soo saarka ee dhexroorka dibadda waa 10 ilaa 120mm iyo dhumucda derbiga waa 1 ilaa 20mm.
Si loo abuuro qiimo aad u badan macaamiisha waa falsafada shirkadeena;Iibsaduhu korriinka waa cayrsigayada shaqo ee loogu talagalay Cold Rolled ASTM 42CrMo Q355b 20# 1045 1035 Dhuumaha birta aan fiicnaynWaxaan si kal iyo laab ah kuugu soo dhawaynaynaa inaad soo booqato shirkadayada ama aad noogu yeedho wada shaqayn!
Si loo abuuro qiimo aad u badan macaamiisha waa falsafada shirkadeena;Koritaanka iibsadaha ayaa ah doonistayada shaqada1035 Saxnaanta Dhuumaha Birta aan Xumaan lahayn, Iyada oo ruuxa "credit marka hore, horumarinta iyada oo hal-abuurnimo, iskaashiga daacad ah iyo koritaanka wadajirka ah", shirkadeena waxa ay ku dadaalayaan in ay abuuraan mustaqbal ifaya idinla leh, si ay u noqdaan madal ugu qiimaha badan ee dhoofinta alaabta our ee Shiinaha!
Dhuumaha birta qaabaysan ee gaarka ah waxa loo qaybin karaa tuubo bir ah oo elliptical ah, tuubo bir ah oo saddex xagal ah, tuubo bir ah oo saddex geesood ah, tuubo bir ah oo rhombic ah, tuubo bir ah oo saddex geesood ah tuubo bir ah oo aan sinnayn, tuubo bir ah oo shan geesle ah oo aan sinnayn, tuubo bir ah oo shan ah oo quincunx ah, tuubo bir ah oo gaar ah tuubo bir ah oo qaab gaar ah u samaysan.
1. Falanqaynta tusmada waxqabadka ee tuubada birta ee qaabka gaarka ah - caag ah
Balaastiggu waxa loola jeedaa awoodda maaddooyinka birta ah si ay u soo saaraan qallafsanaanta caagga ah (qallafsanaanta joogtada ah) iyada oo aan waxyeello loo geysan culeyska.
2. Falanqaynta tusmada waxqabadka ee tuubada birta ee qaabka gaarka ah - adkaanta
Adaggu waa tilmaame lagu cabbiro adkaanta walxaha birta ah.Habka ugu badan ee loo isticmaalo in lagu cabbiro adkaanta wax-soo-saarku waa habka qallafsanaanta, taas oo ah in la isticmaalo indenenter leh joomatari gaar ah si loo cadaadiyo dusha sare ee alaabta birta ah ee la tijaabiyay ee ku hoos jirta culeys gaar ah, lana go'aamiyo qiimaha qallafsanaanta iyada oo loo eegayo heerka darajada. soo gelid.
Hababka inta badan la isticmaalo waxaa ka mid ah adkaanta Brinell (HB), Rockwell hardness (HRA, HRB, HRC) iyo Vickers hardness (HV).
3. Falanqaynta tusmada waxqabadka ee tuubada birta ee qaabka gaarka ah - daal
Xoogga, balaastigga iyo qallafsanaanta kor looga hadlay waa dhammaan tilmaamayaasha sifooyinka farsamada ee biraha ku jira culeyska taagan.Dhab ahaantii, qaybo badan oo mishiin ah ayaa ku shaqeeya culeys wareeg ah, xaaladdan, daal ayaa dhici doona.
4. Falanqaynta tusmada waxqabadka ee tuubada birta ee qaabka gaarka ah - saameynta adag
Culayska ku shaqeeya mishiinka xawaaraha sare waxaa loo yaqaannaa culayska saamaynta, iyo awoodda birta si ay iskaga caabiso dhaawaca hoos yimaada culayska saamaynta waxa loo yaqaannaa adkaanta saamaynta.
5. Falanqaynta tusmada waxqabadka ee tuubada birta ee qaabka gaarka ah - xoogga
Xoog waxaa loola jeedaa iska caabinta walxaha birta ah ee fashilka (qallafsanaanta balaastiigga xad-dhaafka ah ama jabka) hoos yimaada culeys taagan.Maaddaama hababka waxqabadka ee culeyska ay ku jiraan xiisadda, isku-buufinta, foorarsiga iyo dhogorta, xoogga ayaa sidoo kale loo qaybiyaa xoogga xajinta, xoogga cufan, xoogga foorarsiga iyo xoogga dhogorta.Inta badan waxaa jira xiriir gaar ah oo ka dhexeeya awoodo kala duwan.Guud ahaan, xoogga jilicsanaanta ayaa ah tusaha xoogga aasaasiga ah ee la isticmaalo.
