I-Bolt Thread Processing Iingcebiso zeNgcali, funda eli nqaku ngokwaneleyo!

Umsonto wahlulwe ikakhulu waba ngumtya wokudibanisa kunye nokuqhuba ngentambo.

Ukuqhagamshela umsonto, ezona ndlela ziphambili zokucofa, ukucofa, ukujika, ukuziqengqa, ukurabha, njl njl.

Ezi zilandelayo zindlela ngeendlela zokulungisa:

1. Ukusika umsonto

Ngokubanzi, ibhekisa kwindlela yokwenza imisonto kwindawo yokusebenza kunye nokusika isixhobo okanye isixhobo esirhabaxa, ikakhulu kubandakanya ukujika, ukugaya, ukucofa, ukujija, ukugaya kunye nokusika isaqhwithi, njlnjl. Isixhobo somatshini siqinisekisa ukuba isixhobo esiguqukayo, isixhobo sokugaya, okanye ivili lokugaya sinokuhambisa isikhokelo esinye ngokuchanekileyo nangokulinganayo kwicala le-axial yendawo yokusebenza. Ngexesha lokucofa okanye ukufakwa kwesixhobo, isixhobo (cofa okanye ufe) sijikeleza ngokuhambelana nomsebenzi, kwaye isixhobo (okanye isixhobo sokwenza umsebenzi) sihamba ngokukhokelwa yi-axially sikhokelwa yindawo yokuqala eyenziwe ngomsonto.

I-Thread turning on lathe can be done with form turning tool or tool comb tool (jonga isixhobo sokulungisa umsonto). Ukuguqula umsonto ngesixhobo sokuguqula indlela yindlela eqhelekileyo yesiqwengana esinye kunye nemveliso encinci yebhetshi ngenxa yesakhiwo sayo esilula; Ukujika umsonto ngentambo yokusika kunemveliso ephezulu yokusebenza, kodwa ubume besixhobo bunzima, ke kufanelekile kuphela kwimveliso ephakathi kunye nemikhulu ye-workpiece emfutshane enomsonto omncinci. Ngokubanzi, ukuchaneka kwenqaku lokujika umtya we-trapezoidal nge-lathe yesiqhelo kunokufikelela kuphela kwibanga le-8-9 (JB2886-81, efanayo apha ngezantsi); ukuvelisa okanye ukuchaneka kunokuphuculwa ngokubonakalayo xa kusenziwa umsonto kwintambo ekhethekileyo.

2. Umsonto wokugaya

Wokugaya lwenziwa kumatshini wokugaya intambo kunye disc mgawuli okanye ikama mgawuli. I-cutter yokugaya idiski isetyenziselwa ikakhulu ukugaya imisonto yangaphandle ye-trapezoidal kwintonga yesikere, umbungu, kunye nezinye izinto zokusebenza. I-comb milling cutter isetyenziselwa ukusila imisonto eqhelekileyo yangaphakathi nangaphandle kunye nemisonto yokuthinta. Ngenxa yokuba inyingisiwe ngesinqe sokugaya esinee-edge ezininzi kwaye ubude bendawo esebenza kuyo bukhulu kunobude bomsonto oza kulungiswa, indawo yokusebenza inokuqhutywa kuphela nge-1.25 ~ 1.5 yokujikeleza, kwaye imveliso iphezulu kakhulu. Ukuchaneka kwenqaku lokugaya umsonto kunokufikelela kwinqanaba le-8-9, kwaye ubungqongqo bomhlaba yi-R 5-0.63 μm. Le ndlela ifanelekile kwimveliso yobunzima bemisonto yokusebenza ngokuchaneka ngokubanzi okanye ukurhabaxa ngaphambi kokuguba.

3. Umsonto wokugaya

Isetyenziselwa ubukhulu becala imisonto yokuchaneka komsebenzi osebenza nzima kwi-grinder grinder. Ngokweendlela ezahlukeneyo ezinqamlezileyo zevili lokusila, inokwahlulahlulwa ibe yevili lokugaya kunye nelayini yokugaya enemigca emininzi. Iziphumo zibonisa ukuba ukuchaneka kwenqaku levili lokugaya kumgca omnye li-5-6, kwaye umphezulu wobuso yi-R 1.25-0.08 μm, Kukulungele ukugaya ukunxiba ivili. Le ndlela ilungele ukugaya isikhombisi esikhokelayo, umsonto womsonto, umbungu, ibhetshi encinci yomsebenzi osetyenzisiweyo, kunye nokugaya ngokuchanekileyo isitovu. Ukusila kwevili okunemigca emininzi kwahlulwe kwaba yindlela yokugaya ekude kwaye kusikwa kwindlela yokugaya. Ububanzi bevili lokusila kwindlela yokugaya ye-longitudinal bincinci kunobude bomsonto oza kuba ngumhlaba, kwaye umsonto ungaphantsi kumgangatho wokugqibela ngokuhambisa ivili ixesha elide kanye okanye amaxesha aliqela. Ububanzi bevili lokusila lokusika kwindlela yokusila bukhulu kunobude bomsonto oza kuba ngumhlaba. Ivili lokusila lisika kumphezulu womsebenzi ngokusisigxina, indawo yokusebenza inokugqitywa emva kohlaziyo olumalunga ne-1.25. Imveliso iphezulu, kodwa ukuchaneka kuphantsi kancinci, kwaye ukunxitywa kwevili lokusila kunzima kakhulu. Ukusikwa kwindlela yokugaya kufanelekile ekunciphiseni iitephu zokugaya ngebhetshi enkulu kunye nokugaya eminye imisonto yokubopha.
4. Umsonto wokugaya

Uhlobo lwe nut okanye isixhobo esijijwayo sokuqhekeza isixhobo esenziwe ngezinto ezithambileyo ezifana nesinyithi esisetyenzisiweyo sisetyenziselwa ukusila iinxalenye zomsonto owenziwe ngomatshini ngempazamo ye-pitch ngaphambili nangokubuyela umva ujikelezo ukuphucula ukuchaneka kwenqaku. Ukulungiswa komsonto wangaphakathi owomeleleyo kuhlala kususwa ngokusila ukuphucula ukuchaneka.
5. Ukuthinta kunye nokuhlutha

Ukuthinta kukusebenzisa isixa esithile sokujija impompo kumngxunya osezantsi wokugrumba kwendawo yokusebenza ukuze uqhubekeke ngemisonto yangaphakathi. Umkhono kukusebenzisa ukusika ukusika imisonto yangaphandle kwintonga (okanye umbhobho) indawo yokusebenza. Ukuchaneka koomatshini ngokuthinta okanye emkhonweni kuxhomekeke kukuchaneka kwempompo okanye ukufa. Nangona zininzi iindlela zokwenza imisonto yangaphakathi nangaphandle, imisonto yangaphakathi enobubanzi obuncinci inokuxhomekeka ekusetyenzisweni kweetephu. Ukucofa kunye nokufaka imisonto kunokwenziwa ngesandla, njengakumatshini wokukhuphela, oomatshini bokuprinta, ukucofa kunye noomatshini bokufaka umsonto.

Umgaqo wokukhetha wokusika iiparameter zentsimbi yomtya

Kuba umzobo ucacisa inowuthi (okanye ukhokelo) wentambo, isitshixo sokukhetha iiparameter zokusika kukumisela isantya se-spindle "n" kunye nokusika ubunzulu "ap".

1) Ukukhethwa kwesantya sokuluka

Ngokwendlela yokujikeleza kokujija, ukujika kube kanye kwaye isixhobo sondla isikhokelo esinye xa ujika umsonto, isantya sokukhetha esikhethiweyo simisela isantya sokondla se-CNC lathe. Umtya okhokelayo (inowuthi ngentambo enye) kwicandelo lenkqubo yokulungisa intambo ilingana nesantya sokondla "vf" esivezwe kwinqanaba lokutya "f (mm / r)".
vf = nf (1)

Kuyabonakala kwifomula ukuba isantya sokondla "vf" ngokuthe ngqo kwinqanaba lokutya "f". Ukuba isantya sokuluka kwesixhobo somatshini sikhethwe ukuba siphezulu kakhulu, isantya sokondla esiguquliweyo kufuneka siphezulu kakhulu kunesantya sokutya esilinganisiweyo sesixhobo somatshini. Ke ngoko, useto lweparam yenkqubo yesondlo kunye noqwalaselo lombane lwesixhobo somatshini kufuneka kuthathelwe ingqalelo xa ukhetha isantya sokujija xa ujika umsonto, ukunqanda ukwenzeka "komsonto ongasasebenziyo" okanye ibala kufutshane nendawo yokuqala / yokuphela engadibaniyo. iimfuno.

Ngaphandle koko, kufanele kuqatshelwe ukuba xa ulungiso lwentambo luqalisiwe, ixabiso lesantya sokuluka alinakutshintshwa ngokubanzi, kwaye isantya sokuluka kubandakanya ukugqiba ukuhambisa kufuneka kusebenzise ixabiso elikhethiweyo ngexesha lokutya kokuqala. Ngaphandle koko, inkqubo ye-CNC iya kubangela ukuba "umsonto ongasasebenziyo" ngenxa ye "overshoot" yesalathiso sokubetha kwereferensi yentsimbi encoder.

2) Ukukhethwa kobunzulu bokusika

Ngenxa yesixhobo esomeleleyo, amandla okusika amakhulu, kunye nokusika ukutya okukhulu ukusuka kumsonto ojika ukujika ujike, kuyafuneka ngokubanzi ukuba kwenziwe umatshini wokutya kunye nokukhetha ubunzulu obufanelekileyo bokusika ngokokwehla komgangatho. Itheyibhile 1 idwelisa amaxabiso esalathiso samaxesha okutya kunye nokusika ubunzulu bokusika umsonto oqhelekileyo.
