Idle - yintoni na le nto?

Inkqubo uzobe olwenziwe ukutshintsha ubukhulu kunye neemilo amalungu akusoloko ngaphandle olu hlobo lwe machining, bobabini ukutshona. Liguqulwe lithatyathwa kwigama yaseJamani lithetha "indawo", "nzulu". Ukuze ube ngqo ngakumbi, kuba yinkqubo, ngexesha leyo eyandisa ubukhulu le mingxuma. Oku kungenziwa xa kuthelekiswa ne reaming. Countersinking - umsebenzi ngomatshini, nto leyo yenzelwa ngexesha isicefe ezivuzayo, ukuphucula umgangatho nokuchaneka kumphezulu wazo.

imigodi Ukwamkela

Ukuze siqonde kakuhle sendela ntoni, kufuneka ube ufifi lokuba enze njani imingxuma ngokweenkcukacha. Masithi preform kuyimfuneko ukuba sizakugrumba umngxuma kwiklasi yesihlanu okuchaneka sangqa 12 mm.

Oku kuya kufuna ukuba umatshini ukubhola kunye isixhobo 3 zokusebenza: ngokumba, countersink nokuskena. Nganye kwezi zicatshulwa yenzelwe ukusingatha, kuba drill reaming, ukhankase - lo msebenzi efana kakhulu omnye komnye. Ngokuyintloko ukwenza i workpiece usebenzisa isixhobo umngxuma, kodwa ubukhulu yayo kuya kuba ngaphantsi kakhulu kunoko kuyimfuneko, bathi isiqingatha - 6 mm.

Le maholo. Emva koko, kuyimfuneko ukuba alda (operation agqibileyo) countersink ubudeki 12 mm. Ukongeza, core yokomba iya kubonelela 7 iklasi ngendlela.

Ukuze ukuba kuvulwe 5 eklasini, kufuneka usebenzise kwemita yovavanyo. Iza kubonelela imida eziyimfuneko ubungakanani kunye nezibonelelo - ophela kunye umngxuma machining ophela kuyo. Reaming kwaye countersinking abaqhele ukusebenza kwi sangqa enye, kodwa umda ubungakanani ezahlukeneyo, kwaye njengoko engacimekiyo inika iklasi esezantsi okuchaneka, isibonelelo ngenxa deployment ekhethiweyo ngokuchanileyo eliphezulu.

Reaming kanye countersinking

rhoqo la magama bedidekile omnye nomnye ngenxa yokuba ziyafana kakhulu amagama. Noko ke, ukuba yokuzika - inkqubo apho countersink wamzalela ngaphandle lonke ubunzulu inkqubo countersink ekuthiwa phezulu.

Kuyimfuneko ukwenza ezingontsingontsini ngu countersunk iziqalelo intloko eqwalasele (nezitshixo zalo, rivet, izikrufu). Countersink - isixhobo for chamfering yahlukile imilo countersink inxalenye ukusebenza.

Materials ezisingqongileyo countersink

Kanye njengaye nawuphi na isixhobo ukusika, countersink zihlelwe yi uhlobo yokwakha, imilo kunye nohlobo unyango, kwakunye material yenziwe kuzo.

Ekubeni isixhobo iye lukhuni phezulu, ngokuqhelekileyo nto yenziwa speed ngentsimbi eliphezulu, kunjalo, ngokufuthi ingabonwa ukusuka doped countersink constructional (40X) kunye carbon (ST45) ingxubevange.

Idle - kuba smoothing nokucocwa umphezulu, ngoko ke isixhobo ngokwayo kukho inani elikhulu ukunciphisa ezinemiphetho. Countersinks ukuze umsila precast kunye iincakuba detachable, umsila enye idrarhima, ukutyhala-on bayiqhube-esemqoka amaqela.

Xa usibona ngokwembono ngobuchule, ngoko, kakade, izixhobo yemodyuli ayabiza, kodwa ubomi babo ixesha elide, ukususela ngohlangothi sinesiphene kutshintshwa.

Ubude apha

Ukususela ukubhola, reaming - nkqubo iyafana, isixhobo sokugrumba (ingakumbi ngokuphathelele kungajikeleza uqheliso) kunye countersink kufuneka phantse isakhiwo esifanayo. isixhobo nganye yinxalenye ukusika eyenza ngqo umngxuma inxenye.

Umahluko kukuba akukho countersink ezinqamlezayo elidlula, kodwa kukho ukusuka amazinyo ezintathu ukuya kwezintandathu. inxalenye yawo ukusebenza iquka macandelo gauge kunye ahlabayo. UMaSukude ixhomekeke ubunzulu reaming yesibini. Igeyiji - a iirozeti longitudinal ecaleni elidlula. ububanzi yabo ixhomekeke ubukhulu be countersink (0.8-2.5 mm) kunye ukuphakama - 0.2-0.9 mm.

Reaming - umsebenzi ngomatshini, ezifana reaming. Ukuba injongo yawo kukuvumela yazala umngxuma zoncediso zokuba zinqwnqwadelwe, le ubukhulu countersink esikhethwe ezincinci, anikwe isibonelelo nokusebenza yokugqibela iphele. Ngaphezu koko, ekubeni ngendlela efunekayo kule sixhobo lingaphantsi kune ukukrwaqula amaxabiso elililo lungakho kuba kakhulu ngakumbi.

Kwenye imeko, reaming imingxuma - oku kubekho nokuyifeza lokugqibela ezifunekayo iindawo kunye nokunyamezela ka-11, 12 ukuya kwibanga. Ngoko ke isixhobo ikhethiwe isekelwe kwesimilo egciniweyo ukuguga, yaye ububanzi bayo kufuneka ukutshatisa ubukhulu emngxunyeni.

Engineering kunye noyilo

Ukuze ukuba ubukhulu le mingxuma Bekufuneka ngokuchaneke kangangoko kunokwenzeka, usebenza nibonise countersink. Ngaloo ndlela siya kufumana ubukhulu isixhobo kwelona qondo eziyimfuneko ukujonga izinto kunye ukusika inxalenye yalo likwazi ukwenza ukubala ukunciphisa iimeko.

izinto ezibalulekileyo ezichaphazela kwelona qondo values - ke kufuneka izinga. Umzekelo, ukuba kuyimfuneko ukwenza imingxuma countersinking Gqiba nge 85 ubukhulu mm kunye Qualitet H11. emasimini Ngokusekelwe imingxuma nokumelana kweetafile ubukhulu elifikelelekayo-1 ukuya ku-500 mm, ngokuba iklasi umgangatho 11 (ngokuba ngobubanzi ukusuka 80 mm ukuya kwi-120 mm) intsimi wenza le nto: Ixabiso eliphezulu - "220", yaye uphantsi - "0", ngamanye 85 ²²⁰ mm. Ubukhulu bepali liphezulu imingxuma inqwaba ayikwazi ngaphezu 85,22 mm, kwaye ubuncinane - 85 mm.

Kulo mzekelo, ukunyamezelana ntathu - ngumahluko phakathi D _max yaye D _min, ngamanye kuya kuba 0.22 mm. Xa sincokola ngayo umtshato, ngoko ke imingxuma ziya kuthathwa enobubanzi incorrigible ngaphezu 85,22 mm kunye correctable - ngaphantsi kwe-85 mm.
