Inkqubo kunye neemfuno zobugcisa bokuveliswa kweebholiti eziphezulu

1. Ukukhetha izinto eziphathekayo
Intsimbi yeCarbon inobuchule obugqwesileyo, inokudibana noluhlu olubanzi lwendibaniselwano yokusebenza yamandla, kwaye inexabiso eliphantsi xa kuthelekiswa nezinye izinto ezikhawulezayo.
Iipropathi ze-mechanical ze-carbon steel zivakalelwa kwi-carbon content, edla ngokuba ngaphantsi kwe-1.0%. Sihlala sihlula i-carbon steel ephantsi (C% ≤ 0.25%), i-carbon steel medium (0.25% I-0.45%), kunye nentsimbi ye-alloy (ukongeza izinto zokudibanisa kwi-carbon steel eqhelekileyo) ngokusekelwe kumxholo wekhabhoni kwi-carbon steel material.
2. Spheroidization (softening) annealing
(1) Xa i-spheroidized (ithambile) i-annealed countersunk screws kunye ne-hexagonal cylindrical head bolts ziveliswa kusetyenziswa iteknoloji yesihloko esibandayo, isakhiwo sokuqala sentsimbi sichaphazela ngokuthe ngqo isakhono sokwenza ngexesha lokucubungula isihloko esibandayo. Ngethuba lenkqubo yentloko ebandayo, i-deformation yeplastiki kwiindawo zendawo inokufikelela kwi-60% -80%. Ngoko ke, kufuneka ukuba intsimbi ibe neplastiki elungileyo.
(2) Kwintsimbi yekhabhoni ephakathi kunye nentsimbi ye-carbon alloy ephakathi kunye nesixa esikhuluiifasteners eziphezulu, spheroidization (softening) annealing kufuneka kuqhutywe phambi kokubanda isihloko ukufumana iyunifomu kunye nepearlite ecolekileyo spheroidized, ukuze kuhlangatyezwane ngcono neemfuno zemveliso ebonakalayo.
3. Umzobo wocingo
Yolula idiski kwaye usebenzise amandla okutsala ahambelanayo kuyo ukuze ufikelele kwidayamitha yocingo efunekayo (okt ubukhulu) kwimveliso.
Amabakala ombane oqingqiweyo oqingqiweyo kwiiplati ezijikelezayo ezininzi kwiintsimbi zetsimbi ziquka i-M8, i-M10, i-M12, i-M16, njl. Umzekelo, ukuvelisa i-10mm yedayamitha ene-threaded bolt ngokupheleleyo kufuna ukutsalwa kwedayamitha ye-disc ukuya kwi-8.78+0.04mm, ngelixa ukuvelisa i-bolt ye-16mm ye-diameter kufuna i-wire diameter ye-14.38 + 0.02mm.
4.Ukubumba okubandayo
Ukwenziwa kwe hex boltintloko ithatha ukusetyenzwa kweplastiki ebandayo. Xa kuthelekiswa nokucutshungulwa kokusika, i-fiber yensimbi (i-metal wire) iyaqhubeka kunye nokuma kwemveliso ngaphandle kokusika phakathi, ngaloo ndlela iphucula amandla emveliso kunye nokufumana iimpawu ezibalaseleyo zomatshini. Inkqubo yokwenza isihloko esibandayo ibandakanya ukusika kunye nokwenza, isikhululo esinye sokucofa okukodwa, ukucofa kabini isihloko esibandayo, kunye nesihloko esibandayo esizenzekelayo kwizitishi ezininzi.
6. Ukulungiswa kwemisonto
Imisonto yeBolt ilungiswa ngokubanzi ngokusebenza okubandayo, apho izikhewu zemisonto ngaphakathi koluhlu oluthile lwedayamitha zikhuhlwa (ziqengqiwe) ngepleyiti ejijwayo (fa), kwaye imisonto yenziwa luxinzelelo lwepleyiti ejijwayo (i-rolling die). Ukulungelelaniswa kweplastiki yenxalenye ephothiweyo inokufumaneka ngaphandle kokunqunyulwa, okukhokelela ekunyukeni kwamandla, ukuchaneka okuphezulu, kunye nomgangatho ofanayo wemveliso, esetyenziswa ngokubanzi.
Isici esiqhelekileyo sokuhamba (ukuxubha) ukucutshungulwa kwentambo kukuba isantya sokuhamba asifuni ukuba siphezulu kakhulu. Ukuba iphezulu kakhulu, ukusebenza kakuhle kuphantsi kwaye umphezulu wamazinyo wentambo ulungele ukuhlukana okanye ukuxutywa kwentambo. Ngokuchasene noko, ukuba inani lee-revolutions liphantsi kakhulu, i-diameter yentambo ithanda ukulahlekelwa ukujikeleza, kwaye uxinzelelo lokuqala ngexesha lokuqengqeleka luyanda ngokungaqhelekanga, okukhokelela kubomi obufutshane bokungunda.
7. Unyango lobushushu
Ukunyangwa kobushushuiifasteners eziphezulukufuneka bangene kunyango lokucinywa kunye nokufudumeza ngokweemfuno zobugcisa ukuphucula iimpawu zomatshini ezibanzi zeziqhoboshi kunye nokuhlangabezana namaxabiso achaziweyo okuqina kunye nomlinganiselo wesivuno semveliso.
Ngenxa yomthamo omkhulu wemveliso kunye nexabiso eliphantsi leebholiti eziphezulu zokuqina, kunye nolwakhiwo oluthambileyo noluchanekileyo lwenxalenye ephothiweyo, kuyafuneka ukuba isixhobo sonyango lobushushu sibe nemveliso ehambelanayo eyomeleleyo, iqondo eliphezulu lokuzisebenzela, kunye nomgangatho wonyango wobushushu obuphezulu. Ukuze kuveliswe iziqhoboshi ezikumgangatho ophezulu, izixhobo zobuchwepheshe bonyango oluphezulu ziyimfuneko.
