7 Iindlela zokuLungisa imisonto

1. Ukusika imisonto

Ngokubanzi, kubhekiselele kumatshini wokwenza intambo kwisixhobo sokubumba okanye sokusila, ikakhulu kubandakanywa ukujika, ukugaya, ukucofa nokucofa ukucola, ukugaya, ukusika isivunguvungu, njl njl. isixhobo somatshini siqinisekisa ukuba isixhobo sokujika, isisiki sokusila, okanye ivili lokugaya lihambisa ilothe ngokuchanekileyo nangokulungeleleneyo kwicala leaxial yesixhobo sokusebenza zonke. ukujikeleza kwendawo yokusebenza. Xa ucofa okanye ukuthunga, isixhobo (itephu okanye ufe) ujikeleza ngokumalunga nomsebenzi, kwaye i-groove yokuqala eyenziwe ngentambo ikhokela isixhobo (okanye i-workpiece) ukuhamba nge-axially.

 

2. Ukujika imisonto

Izixhobo zekhadi zingasetyenziselwa ukujika okanye ukudibanisa intambo kwi-lathe (jonga isixhobo sokucubungula intambo). Ukuguqula intambo kunye nokwenza isixhobo 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 kunokuphuculwa kakhulu xa umatshini wokwenza intambo kwilathe ekhethekileyo.CNC machining inxalenye

 

3. Ukugaya imisonto

Umsiki wokusila idisc okanye umsiki wekama wokusila usetyenziselwa ukugaya kumatshini wokusila intambo. I-disc milling cutter isetyenziselwa ikakhulu kwi-milling trapezoid imisonto yangaphandle ye-screw rods, iintshulube, kunye nezinye izinto zokusebenza. Ngenxa yokuba inxalenye yayo yokusebenza ide kunobude bomsonto oza kuqhutyelwa yi-multi-edge milling cutter, i-workpiece inokucutshungulwa kuphela ngokujikeleza i-1.25-1.5 revolutions, kunye nemveliso ephezulu. Ukuchaneka kwepitch yokugaya intambo kunokufikelela kumabakala angama-8-9, kwaye uburhabaxa bomphezulu yi-r5-0.63 μ M. Le ndlela ifanelekile kwimveliso yobuninzi bemisonto echanekileyo yokuchaneka ngokubanzi okanye umatshini orhabaxa phambi kokusila.CNCc inxalenye yokugaya

 

4. Ukusila imisonto

Isetyenziselwa ikakhulu ukucubungula intambo echanekileyo ye-workpiece eqinile kwi-grinder yentambo. Ngokweemilo ezinqamlezayo ezinqamlezayo zevili lokusila, linokwahlulwa libe ziindidi ezimbini: ivili lokusila lomgca omnye kunye nevili lokusila lemigca emininzi. Ukuchaneka kwe-pitch yevili lokugaya umgca owodwa ngamabakala angama-5-6, kwaye ubunzima bomhlaba bu-r1.25-0.08 μ m, ngoko kulungele ukugqiba ivili lokugaya. Le ndlela ifanelekile ekusileni izikrufu ezichanekileyo, iigeyiji zentambo, iintshulube, iibhetshi ezincinci zemisonto yokusebenza, kunye ne-hob echanekileyo Iindidi ezimbini zokusila zazikhona: ukucola okude kunye nokusikwa kokusila. Ububanzi bevili lokusila kunye nendlela yokugaya i-longitudinal ingaphantsi kobude bomsonto oza kucolwa, kwaye intambo inokucolwa ukuya kubukhulu bokugqibela emva kokuba ivili lokusila lihamba ngobude kanye okanye amaxesha amaninzi. Ububanzi bevili lokugaya lendlela yokugaya i-cut-in bukhulu kunobude bomsonto oza kwenziwa. Ivili lokusila linqumla kumphezulu we-workpiece radially, kwaye i-workpiece inomhlaba emva kokujika malunga ne-1.25 revolutions. Imveliso iphezulu, kodwa ukuchaneka kuncinci, kwaye ukugqoka ivili lokugaya kunzima ngakumbi. Indlela yokusila yokusika ilungele ukuhlatywa izixa ezikhulu zeetephu kunye nokusila imisonto ethile.inxalenye yeplastiki

 

5. Ukusila imisonto

Uhlobo lwe-nut okanye i-screw-type-thread-lapping tool yenziwe ngezinto ezithambileyo ezifana nentsimbi. Amalungu omsonto ogqityiweyo kwi-workpiece enempazamo ye-pitch aphantsi ngokujikeleza phambili kunye nokubuyisela umva ukuphucula ukuchaneka kwe-pitch. Intambo yangaphakathi eqinile idla ngokuchithwa ngokusila ukuphucula ukuchaneka.

 

6. Ukucofa kunye nokuthunga

Ukucofa kukusebenzisa itorque ethile ukujija impompo kumngxuma osezantsi ogrunjiweyo 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 kufa. Nangona kukho iindlela ezininzi zokucutshungulwa kwangaphakathi nangaphandle, iintambo zangaphakathi ezinobubanzi obuncinci zinokucutshungulwa kuphela ngeetephu. Ukucofa nokuthunga kunokwenziwa ngesandla okanye ngelathe, umatshini wokomba, umatshini wokucofa, kunye noomatshini bokuthunga.

 

7. Ukuqengqeleka komsonto

Indlela yokucubungula yokwenza kunye nokuqengqeleka kwefa ukuvelisa i-deformation yeplastiki ye-workpiece ukufumana ukuqengqeleka kwentambo ngokuqhelekileyo kuqhutyelwa kumatshini wokugubungela intambo okanye i-lathe ezenzekelayo edityaniswe nentloko yokuvula kunye nokuvala intambo, efanelekileyo kwimveliso yobuninzi. ipateni yomsonto yangaphandle yeziqhoboshi ezisemgangathweni kunye namanye amalunga adityanisiweyo. 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. Sekunjalo, kwi-workpiece ethambileyo, intambo yangaphakathi ebandayo ye-extrusion ingasetyenziselwa 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.

Iinzuzo zokuqengqeleka komsonto zezi zilandelayo:

① uburhabaxa bomphezulu bungaphantsi kunokujika, 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, kwaye ukuchaneka kunye nobunzima be-rolling die nabo buphezulu, ngoko kunzima ukuvelisa ukufa. Ayifanelekanga kwimicu eneprofayili yokuqengqeleka eyi-asymmetric.

 

Ngokutsho kwee-dies ezahlukeneyo zokuqengqeleka, ukuqengqeleka komsonto kunokohlulwa kube ziindidi ezimbini: ukuqengqeleka komsonto kunye nokuqengqeleka kwentambo.

 

Ukuqengqeleka komsonto: iipleyiti ezimbini eziqengqelekayo ezinemisonto yeeprofayili ziyagxadazwa kwaye zicwangciswe nge-1/2 pitch. Ipleyiti engatshintshiyo igxininisekile, kwaye ipleyiti ehambayo ihamba kumgca ochanekileyo ohambelanayo kunye neplate emileyo. Xa i-workpiece ithunyelwa phakathi kwamacwecwe amabini, ipleyiti ehambayo iqhubela phambili ukuxubha kwaye icinezele i-workpiece, yenza i-deformation yayo yeplastiki kunye nokwenza intambo.

Zintathu iindidi zokuqengqeleka: iradial, tangential,g, kunye nokuqengqeleka kwentloko.

 

① Ukuqengqeleka kwentambo yeRadial: amavili amabini (okanye amathathu) amilise okwentambo afakwe kwishafti ezihambelanayo, indawo yokusebenza ibekwe kwinkxaso phakathi kwamavili amabini, kwaye amavili amabini ajikeleza ngesantya esifanayo kwicala elinye, elinye. nayo yenza intshukumo yeradial feed. Ivili elijikelezayo liqhuba i-workpiece ukuba ijikeleze, kwaye umphezulu ukhutshwe nge-radially ukwenza intambo. Indlela efanayo yokuqengqeleka ingasetyenziselwa ezinye izikrufu ezineemfuno ezichanekileyo ezisezantsi.

 

②ukuqengqeleka komsonto: okwakwaziwa njengokuqengqeleka komsonto weplanethi. Isixhobo sokuqengqeleka siquka ivili elijikelezayo elijikelezayo eliphakathi kunye neepleyiti ezintathu ezizinzileyo ezimile okwearc. I-workpiece inokondliwa ngokuqhubekayo ngexesha lokuqengqeleka, ngoko ke imveliso iphezulu kunokuba i-thread rubbing kunye ne-radial rolling.

 

③ Ukuqengqeleka komsonto wentloko eqengqelekayo: iqhutywa 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.
