Indlela yokucubungula imicu ehlukahlukene yangaphakathi neyangaphandle ngamathuluzi okucubungula intambo.

1 ukusika intambo

 

Ngokuvamile, kubhekiselwa endleleni yokwenza intambo kucezu lokusebenza ngethuluzi lokwakha noma ithuluzi lokugaya, ikakhulukazi okuhlanganisa ukuphenduka, ukugaya, ukuthepha kanye nokucupha ukugaya, ukugaya nokusika isivunguvungu, njll. Lapho uphendula, ugaya futhi ugaya intambo, iketango ithuluzi lomshini liqinisekisa ukuthi ithuluzi lokuguqula, i-milling cutter noma isondo lokugaya lihambisa umthofu ngokunembile futhi ngokulinganayo eduze nokuqondisa kwe-axial ye-workpiece njalo ukujikeleza kwendawo yokusebenza. Uma uthepha noma ucucuza, ithuluzi (thepha noma shona) lizungeza ngokuhlobene nendawo yokusebenza, futhi i-groove yokuqala eyakhiwe iqondisa ithuluzi (noma ucezu lokusebenza) ukuhamba nge-axially.

 

2 ukuphenduka kwentambo

Ukwakha ithuluzi lokujika noma ithuluzi lokuqopha intambo lingasetshenziselwa ukuvula intambo ku-lathe (bona ithuluzi lokucubungula intambo). Ukuguqula intambo ngethuluzi lokuguqula ukwakha kuyindlela evamile yesiqeshana esisodwa kanye nokukhiqizwa kwe-batch encane ye-workpiece yentambo ngenxa yesakhiwo sayo esilula; intambo yokujika ngethuluzi lokukama intambo inokukhiqiza okuphezulu, kepha ukwakheka kwayo kuyinkimbinkimbi, ngakho-ke ifaneleka kuphela ukuguqula i-workpiece yentambo emfushane enamazinyo amahle ekukhiqizeni i-batch ephakathi nendawo enkulu. Ukunemba kwephimbo lokuguqula intambo ye-trapezoidal ene-lathe evamile ingafinyelela kuphela amazinga angu-8-9 (jb2886-81, okufanayo ngezansi); ukukhiqiza noma ukunemba kungathuthukiswa kakhulu lapho kwenziwa intambo ku-lathe yentambo ekhethekile.

 

3 ukugaya intambo

Emshinini wokugaya intambo, i-disc milling cutter noma i-comb milling cutter isetshenziselwa ukugaya. I-Disc milling cutter isetshenziselwa kakhulu ukugaya intambo ye-trapezoid yangaphandle ye-screw rod, worm nezinye izinto zokusebenza. I-Comb milling cutter isetshenziselwa ukugaya intambo evamile yangaphakathi nangaphandle kanye nentambo ye-taper. Ngenxa yokuthi ubude bengxenye yayo yokusebenza bude kunobude bentambo okufanele icutshungulwe yi-multi-edge milling cutter, i-workpiece ingacutshungulwa kuphela ngokuzungeza ama-revolutions angu-1.25-1.5, ngokukhiqiza okuphezulu. Ukunemba kwephimbo lokugaywa kwentambo kungafinyelela kumabanga angu-8-9, futhi ubulukhuni obungaphezulu bungu-r5-0.63 μ M. Le ndlela ifanele ukukhiqizwa ngobuningi bendwangu yokusebenza yentambo enembayo noma ukugaywa okuqinile ngaphambi kokugaya.

 

4 ukugaya intambo

Isetshenziswa kakhulu ukucubungula intambo enembayo ye-workpiece eqinile kumshini wokugaya intambo. Ngokwesimo esihlukene se-cross-section yesondo lokugaya, lingahlukaniswa ngezinhlobo ezimbili: isondo lokugaya umugqa owodwa kanye nesondo lokugaya imigqa eminingi. Ukunemba kwephimbo lesondo lokugaya lomugqa owodwa kungamabanga angama-5-6, futhi ubulukhuni obungaphezulu bungu-r1.25-0.08 μ m, ngakho-ke kulula ukuqeda isondo lokugaya. Le ndlela ilungele ukugaya ngokunemba isikulufu, igeji yokukala intambo, isikelemu, iqoqo elincane le-workpiece yentambo kanye ne-hob enembayo. Kunezinhlobo ezimbili zezindlela zokugaya: ukugaya i-longitudinal kanye nokusika ekugayeni. Ububanzi besondo lokugaya ngendlela yokugaya i-longitudinal bungaphansi kobude bentambo okufanele igaywe, futhi intambo ingagaywa ibe usayizi wokugcina ngemva kokuba isondo lokugaya lihamba ngobude kanye noma izikhathi eziningana. Ububanzi besondo lokugaya lendlela yokugaya bukhulu kunobude bentambo okufanele igaywe. Isondo lokugaya lisika ebusweni be-workpiece radially, futhi i-workpiece ingagaywa ngemuva kokuphenduka okungaba ngu-1.25. Ukukhiqiza kuphakeme, kodwa ukunemba kuphansi kancane, futhi ukugqoka kwesondo lokugaya kuyinkimbinkimbi. Indlela yokugaya ilungele ukufofa ompompi abaningi nokugaya izintambo zokubopha. Ukucubungula kwensimbi, kufanelekile ukunakwa!

 

5 ukugaya intambo

Uhlobo lwenati noma ithuluzi lokuhlanganisa intambo yohlobo lwesikulufu lenziwe ngezinto ezithambile njengensimbi ekhonjiwe. Izingxenye zochungechunge olucutshunguliwe endaweni yokusebenza enephutha lephimbo zigaywa ngokuzungezisa phambili nokuhlehla ukuze kuthuthukiswe ukunemba kwephimbo. Intambo yangaphakathi eqinile ivame ukuqedwa ngokugaya ukuze kuthuthukiswe ukunemba.

 

 

6 ukushaya nokulutha

 

Ukuthepha kuwukusebenzisa i-torque ethile ukugoqa umpompi embotsheni engaphansi ebhojwe ngaphambili endaweni yokusebenza ukuze kucutshungulwe umucu wangaphakathi.

I-threading ukusika intambo yangaphandle kubha (noma ishubhu) ucezu lokusebenzela ngedayizi. Ukunemba komshini kokuthepha noma ukuthunga kuncike ekunembeni kompompi noma ukufa. Nakuba ziningi izindlela zokucubungula imicu yangaphakathi neyangaphandle, imicu yangaphakathi enobubanzi obuncane ingacutshungulwa kuphela ngompompi. Ukuthepha nokuhlanganisa kungenziwa ngesandla noma nge-lathe, umshini wokubhoboza, umshini wokudonsa kanye nomshini wokulutha.

 

 

7 ukugingqa intambo

Indlela yokucubungula yokwenza kanye ne-rolling die ukukhiqiza ukuguqulwa kwepulasitiki ye-workpiece ukuze uthole ukugoqa kwentambo ngokuvamile kwenziwa emshinini wokugoqa intambo noma i-lathe ezenzakalelayo exhunywe ngokuvula okuzenzakalelayo nokuvala intambo ekhanda eligoqayo, elifanele ukukhiqizwa kwenqwaba yentambo yangaphandle. iphethini yezinsimbi ezijwayelekile kanye namanye amalunga anentambo. Ngokuvamile, ububanzi obungaphandle bentambo yokugoqa abukho ngaphezu kuka-25 mm, ubude abukho ngaphezu kwe-100 mm, futhi ukunemba kwentambo kungafinyelela ezingeni 2 (gb197-63). Ububanzi bento engenalutho esetshenzisiwe bucishe bulingane nobubanzi bephimbo lentambo ezocutshungulwa. Ngokuvamile, intambo yangaphakathi ayikwazi ukucutshungulwa ngokugoqa, kodwa ku-workpiece ethambile, intambo yangaphakathi ye-extrusion ebandayo ingasetshenziswa ngaphandle kompompi we-slot extrusion (ububanzi obukhulu bungafinyelela cishe ku-30mm), futhi isimiso sokusebenza sifana nokuthepha. I-torque edingekayo ekukhipheni okubandayo kwentambo yangaphakathi icishe ibe yinkulu ngokuphindwe ngo-1 kunaleyo yokuthepha, futhi ukunemba komshini kanye nekhwalithi yendawo ephezulu iphakeme kancane kunaleyo yokuthepha.

 

Izinzuzo zokugingqa intambo zimi kanje: ① ubuhwaqane obungaphezulu bungaphansi kokuphenduka, ukugaya nokugaya; ② ingaphezulu lentambo ngemva kokugingqika lingathuthukisa amandla nobulukhuni ngenxa yokuqina komsebenzi obandayo; ③ izinga lokusebenzisa impahla liphezulu; ④ ukukhiqiza kuphindwe kabili uma kuqhathaniswa nenqubo yokusika, futhi kulula ukuqaphela okuzenzakalelayo; ⑤ impilo yesevisi ye-rolling die yinde kakhulu. Kodwa-ke, ukuqina kwe-workpiece material abukho ngaphezu kwe-hrc40, ukunemba kosayizi ongenalutho kuyadingeka ukuba kube phezulu, ukunemba nokuqina kwe-rolling die nakho kuyadingeka ukuba kube phezulu, ngakho-ke kunzima ukwenza ukufa, futhi ayilungele intambo enephrofayili egoqayo e-asymmetric.

 

Ngokusho kwedayidi ehlukahlukene yokugoqa, ukugoqa intambo kungahlukaniswa ngezinhlobo ezimbili: ukugoqa intambo nokugingqa intambo.

 

Amapuleti amabili aginqikayo anephrofayili yentambo anyakaziswa ngu-1/2 wokuphakama, futhi ipuleti elimile ligxilile, futhi ipuleti elinyakazayo lihamba ngomugqa oqondile ophindaphindayo ohambisana nepuleti elimile. Ufuna ukufunda ukuhlelwa kwe-UG eqenjini 565120797 kungakusiza, lapho ucezu lokusebenza luba amapuleti amabili, ukuhambisa ipuleti phambili ukuze uhlikihle futhi ucindezele ucezu lokusebenza, wenze ukuguqulwa kwayo kwepulasitiki kube intambo.

 

Kunezinhlobo ezintathu zokugingqa: ukugoqa kwe-radial, ukugoqa okune-tangential kanye nokugingqa kwekhanda.

① Ukugingqa intambo eyi-radial: amasondo amabili (noma amathathu) okugoqa intambo afakwe emiphini ehambisanayo, i-workpiece ibekwe phezu kokusekelwa phakathi kwamasondo amabili, futhi amasondo amabili azungeza ngesivinini esifanayo ohlangothini olufanayo, elilodwa eyenza futhi ukunyakaza kwe-radial feed. I-workpiece iqhutshwa isondo eligoqayo ukuze lijikeleze, futhi indawo engaphezulu ikhishwa nge-radially ukuze yakhe intambo. Indlela yokugingqa efanayo ingasetshenziswa kwezinye izikulufu ezinezidingo zokunemba okuphansi.

(2) ukugingqa intambo ye-tangential: eyaziwa nangokuthi ukugoqa kwentambo yeplanethi. Ithuluzi eligoqayo liqukethe isondo elijikelezayo elimaphakathi elizungezayo kanye namapuleti entambo amathathu amile amise okwe-arc. Ngesikhathi sokugoqa, i-workpiece ingaphakelwa ngokuqhubekayo, ngakho-ke ukukhiqiza kuphezulu kunokokuhlikihla kwentambo nokugoqeka kwe-radial.

③ ukugoqa intambo yekhanda eligoqayo: kwenziwa kwi-lathe ezenzakalelayo futhi ngokuvamile isetshenziselwa ukucubungula intambo emfushane endaweni yokusebenza. Kunama-roller angama-3-4 asatshalaliswa ngokulinganayo endaweni yokusebenza. Lapho ugoqa, i-workpiece iyajikeleza, futhi ikhanda eligoqayo lidla i-axially ukuze ikhiphe umsebenzi ngaphandle kwentambo.
