Indlela yokucubungula imisonto eyahlukeneyo yangaphakathi nangaphandle kunye nezixhobo zokulungisa intambo.

1 ukusika intambo

 

Ngokubanzi, ibhekisa kwindlela yokwenza intambo kwisixhobo sokwenza isixhobo okanye isixhobo sokusila, ikakhulu kubandakanywa ukujika, ukugaya, ukucofa kunye nokuthunga ukucola, ukusila kunye nokusika kwesaqhwithi, njl njl. isixhobo somatshini siqinisekisa ukuba isixhobo sokuguqula, i-milling cutter okanye ivili lokugaya lihambisa isikhokelo ngokuchanekileyo nangokulinganayo ecaleni kwe-axial ye-workpiece yonke ukujikeleza kwendawo yokusebenza. Xa ucofa okanye ukuthunga, isixhobo (itephu okanye ufe) ujikeleza ngokunxulumene nomsebenzi, kwaye i-groove yokuqala eyenziwe ngentambo ikhokela isixhobo (okanye i-workpiece) ukuhamba nge-axially.

 

2 ukujika komsonto

Ukwenza isixhobo sokuguqula okanye isixhobo sokwenza amakhadi entambo singasetyenziselwa ukujika intambo kwilathe (jonga isixhobo sokwenza umsonto). Ukuguqula intambo kunye nesixhobo sokuguqula indlela eqhelekileyo yesiqwenga esisodwa kunye nokuveliswa kwebhetshi encinci ye-workpiece yentambo ngenxa yesakhiwo sayo esilula; ukujika intambo ngesixhobo sokuhlanganisa intambo inomgangatho ophezulu wemveliso, kodwa ubume bayo buntsonkothile, ngoko ke ilungele kuphela ukuguqula umsonto omfutshane wokusebenza kunye namazinyo amahle kwimveliso yebhetshi ephakathi kunye nenkulu. Ukuchaneka kwe-pitch yokuguqula intambo ye-trapezoidal kunye ne-lathe jikelele inokufikelela kuphela kumanqanaba e-8-9 (jb2886-81, efanayo ngezantsi); imveliso okanye ukuchaneka kungaphuculwa kakhulu xa machining thread on specialised thread lathe.

 

3 ukugaya imisonto

Kumatshini wokugaya intambo, idiskhi yokusila okanye i-comb milling cutter isetyenziselwa ukugaya. I-Disc milling cutter isetyenziselwa ikakhulu ukucola umsonto wetrapezoid wangaphandle we-screw rod, worm kunye nezinye izixhobo zokusebenza. I-Comb milling cutter isetyenziselwa ukugaya intambo eqhelekileyo yangaphakathi nangaphandle kunye ne-taper thread. Ngenxa yokuba ubude becandelo layo lokusebenza lide kunobude bomsonto oza kucutshungulwa yi-multi edge milling cutter, i-workpiece inokucutshungulwa kuphela ngokujikeleza i-1.25-1.5 revolutions, kunye nemveliso ephezulu. Ukuchaneka kwe-pitch yokugaya intambo kunokufikelela kumabakala angama-8-9, kwaye uburhabaxa bomphezulu yi-r5-0.63 μ M. Le ndlela ifanelekile kwimveliso yobuninzi be-workpiece yomsonto ochanekileyo okanye umatshini ongqongqo ngaphambi kokugaya.

 

4 ukucola intambo

Isetyenziselwa ikakhulu ukucubungula intambo echanekileyo ye-workpiece eqinile kwi-grinder yentambo. Ngokwemilo eyahlukileyo yecandelo elinqamlezayo levili lokusila, linokohlulwa libe ziindidi ezimbini: ivili lokusila lomgca omnye kunye nevili lokusila lomgca omninzi. Ukuchaneka kwe-pitch yevili elilodwa lokusila ngamabakala angama-5-6, kwaye uburhabaxa bomhlaba bu-r1.25-0.08 μ m, ngoko kulungele ukugqiba ivili lokugaya. Le ndlela ilungele ukugaya ngokuchanekileyo isikrufu, igeyiji yomsonto, intshulube, ibhetshi encinci yomtya wokusebenza wentambo kunye nesitovu esichanekileyo. Kukho iintlobo ezimbini zeendlela zokusila: ukugaya i-longitudinal kunye nokusika ekusileni. Ububanzi bevili lokusila kunye nendlela yokugaya i-longitudinal ingaphantsi kobude bomsonto oza kugutyungelwa, kwaye intambo inokucolwa ukuya kubukhulu bokugqibela emva kokuba ivili lokugaya lihamba ngobude kanye okanye amaxesha amaninzi. Ububanzi bevili lokusila kwindlela yokusila bukhulu kunobude bomsonto oza kugaywa. Ivili lokugaya linqumla kumphezulu we-workpiece radially, kwaye i-workpiece inokucolwa emva kokujika malunga ne-1.25 revolutions. Imveliso iphezulu, kodwa ukuchaneka kuncinci, kwaye ukugqoka ivili lokugaya kunzima ngakumbi. Indlela yokusila ilungele ukuhlatywa izixa ezikhulu zeetephu kunye nokusila imisonto ethile. Ukulungiswa kwesinyithi, kufanelekile ukuqwalaselwa!

 

5 intambo yokusila

Uhlobo lwentongomane okanye isixhobo sohlobo lokujija umsonto senziwe ngezinto ezithambileyo ezifana nentsimbi. Amalungu omsonto ogqityiweyo kwi-workpiece enempazamo ye-pitch igaywe ngokujikeleza phambili kunye nokubuyisela umva ukuphucula ukuchaneka kwe-pitch. Intambo yangaphakathi eqinile idla ngokuchithwa ngokusila ukuphucula ukuchaneka.

 

 

6 ukutefa kunye nokuthunga

 

Ukucofa kukusebenzisa itorque ethile ukujija impompo kumngxuma osezantsi ogrunjwe kwangaphambili kwisixhobo sokusebenza ukuqhubekekisa umsonto wangaphakathi.

I-threading kukusika intambo yangaphandle kwi-bar (okanye ityhubhu) i-workpiece kunye ne-die. Ukuchaneka komatshini wokucofa okanye ukuthunga kuxhomekeke ekuchanekeni kompompo okanye ukufa. Nangona kukho iindlela ezininzi zokucutshungulwa kwangaphakathi nangaphandle, iintambo zangaphakathi ezinobubanzi obuncinci zinokucutshungulwa kuphela ngeempompo. Ukucofa kunye nokuthunga kungenziwa ngesandla okanye nge-lathe, umatshini wokugaya, umatshini wokucofa kunye nomatshini wokuthunga.

 

 

7 ukuqengqeleka komsonto

Indlela yokucubungula yokwenza kunye nokuqengqeleka kokufa ukuvelisa ukuguqulwa kweplastiki ye-workpiece ukufumana ukuqengqeleka kwentambo ngokuqhelekileyo kuqhutyelwa kumatshini wokugubungela intambo okanye i-lathe ezenzekelayo edityaniswe ngokuvula okuzenzekelayo kunye nokuvala intambo ejikelezayo, efanelekileyo kwimveliso yobuninzi bomsonto wangaphandle. ipateni yeziqhoboshi ezisemgangathweni kunye nezinye iintambo ezinemisonto. Ngokuqhelekileyo, i-diameter yangaphandle yentambo yokujikeleza ayikho ngaphezu kwe-25 mm, ubude abukho ngaphezu kwe-100 mm, kwaye ukuchaneka kwentambo kunokufikelela kwinqanaba le-2 (gb197-63). Idayamitha yesithuba esingenanto esetyenzisiweyo ilingana ngokulinganayo nobubanzi bepitshi yomsonto oza kucutshungulwa. Ngokuqhelekileyo, intambo yangaphakathi ayinakucutshungulwa ngokuqengqeleka, kodwa kwi-workpiece ethambileyo, intambo yangaphakathi ebandayo ye-extrusion ingasetyenziswa ngaphandle kwempompo ye-slot extrusion (ubukhulu bobukhulu bunokufikelela malunga ne-30mm), kwaye umgaqo wokusebenza ufana nokucofa. I-torque efunekayo kwi-extrusion ebandayo yentambo yangaphakathi imalunga namaxesha angama-1 amakhulu kunokokucofa, kwaye ukuchaneka komatshini kunye nomgangatho womphezulu uphezulu kancinci kunoko wokucofa.

 

Iingenelo zokuqengqeleka komsonto zezi zilandelayo: ① uburhabaxa bomphezulu bungaphantsi kokujika, ukungqusha kunye nokusila; ② umphezulu wentambo emva kokuqengqeleka unokuphucula amandla kunye nobunzima ngenxa yokuqina komsebenzi obandayo; ③ izinga lokusetyenziswa kwezinto liphezulu; ④ imveliso iphindwe kabini xa ithelekiswa nenkqubo yokusika, kwaye kulula ukuyiqonda i-automation; ⑤ ubomi benkonzo ye-rolling die bude kakhulu. Nangona kunjalo, ubunzima bomsebenzi we-workpiece abukho ngaphezu kwe-hrc40, ukuchaneka kobukhulu obungenanto bufunekayo ukuba buphakame, ukuchaneka kunye nokuqina kwe-rolling die nayo kufuneka ibe phezulu, ngoko kunzima ukuvelisa ukufa, kwaye ayifanelekanga kumsonto kunye neProfayili yokuqengqeleka kwe-asymmetric.

 

Ngokwendlela eyahlukileyo yokuqengqeleka, ukuqengqeleka komsonto kunokohlulwa kube ziindidi ezimbini: ukuqengqeleka komsonto kunye nokuqengqeleka kwentambo.

 

Iipleyiti ezimbini ezijikelezayo ezineprofayili yomsonto ziyagxadazwa yi-1 / 2 pitch, kwaye ipleyiti engatshintshiyo ilungisiwe, kwaye ipleyiti ehambayo ihamba ngomgca obuyelayo othe tye ohambelana nepleyiti engatshintshiyo. Ufuna ukufunda inkqubo ye-UG kwiqela le-565120797 inokukunceda, xa i-workpiece ibe ngamacwecwe amabini, uhambisa ipleyiti phambili ukuze uhlikihle kwaye ucinezele i-workpiece, ukwenza i-deformation yayo yeplastiki ibe ngumsonto.

 

Zintathu iindidi zokuqengqeleka: ukuqengqeleka kwe-radial, ukuqengqeleka kwe-tangential kunye nokuqengqeleka kwentloko.

① Ukuqengqeleka kwentambo yeradial: amavili amabini (okanye amathathu) amilise okwentambo afakwe kwishafti ezidityanisiweyo, i-workpiece ibekwe kwinkxaso phakathi kwamavili amabini, kwaye amavili amabini ajikeleza ngesantya esifanayo kwicala elinye, elinye lamavili. eyenza kwakhona intshukumo ye-radial feed. I-workpiece iqhutywe yivili elijikelezayo ukuze lijikeleze, kwaye umphezulu ukhutshwe ngokusasaza ukwenza intambo. Indlela yokuqengqeleka efanayo inokusetyenziselwa ezinye izikrufu ezineemfuno ezichanekileyo ezisezantsi.

(2) ukuqengqeleka komsonto wetangential: okwakwaziwa njengokuqengqeleka komsonto weplanethi. Isixhobo sokuqengqeleka siquka ivili elijikelezayo elijikelezayo eliphakathi kunye neepleyiti ezintathu ezizinzileyo ezimile okwearc. Ngexesha lokuqengqeleka, i-workpiece inokondliwa ngokuqhubekayo, ngoko ke imveliso iphezulu kuneyokuxutywa kwentambo kunye ne-radial rolling.

③ Ukuqengqeleka komsonto wentloko eqengqelekayo: yenziwa kwilathe ezenzekelayo kwaye isetyenziswa ngokubanzi ukusetyenzwa komsonto omfutshane kwisixhobo sokusebenza. Kukho ii-roller ezi-3-4 ezisasazwa ngokufanayo kwi-workpiece. Xa uqengqeleka, i-workpiece ijikeleza, kwaye intloko eqengqelekayo itya i-axially ukuze ikhuphe i-workpiece ngaphandle kwentambo.
