Thepha ukuhlelwa

1. Umpompi wokusika
1) Ompompi bomtshingo oqondile: basetshenziselwa ukucubungula ngezimbobo nezimbobo eziyimpumputhe.Ama-iron chips akhona kuma-grooves ompompi, futhi ikhwalithi yezintambo ezicutshunguliwe ayikho phezulu.Zivame ukusetshenziselwa ukucubungula izinto ezimfishane, njengensimbi empunga;
2) Impompi ye-Spiral groove: isetshenziselwa ukucubungula imbobo eyimpumputhe ngokujula kwembobo okungaphansi noma okulingana ne-3D.Ama-iron chips akhishwa eduze kwe-spiral groove, futhi ikhwalithi ye-thread surface iphezulu;
10~20° i-engeli ye-helix kampompi ingacubungula ukujula kwentambo ngaphansi noma okulingana no-2D;
28~40° i-engeli ye-helix kampompi ingacubungula ukujula kwentambo ngaphansi noma okulingana no-3D;
I-50° helix angle tap ingacubungula ukujula kwentambo ngaphansi noma okulingana no-3.5D (isimo esikhethekile sokusebenza esingu-4D);
Kwezinye izimo (izinto eziqinile, iphimbo elikhulu, njll.), ukuze uthole amandla angcono wethiphu yezinyo, ompompi bomtshingo ovunguzayo bazosetshenziswa ukucubungula ngezimbobo;
3) Ompompi bamaphoyinti okuvunguza: ngokuvamile asetshenziselwa izimbobo kuphela, isilinganiso sobude ukuya kububanzi singafinyelela ku-3D~3.5D, ama-chip chips akhishelwa phansi, itorque yokusika incane, futhi ikhwalithi yangaphezulu yezintambo ezicutshunguliwe iphezulu.Ibizwa nangokuthi i-edge angle tap.noma ithiphu kampompi;
2. Umpompi wokukhipha
Ingasetshenziselwa ukucubungula ngokusebenzisa izimbobo nezimbobo eziyimpumputhe.Izinyo shape kwakheka ngokusebenzisa deformation plastic of the material.Ingasetshenziswa kuphela ukucubungula izinto zepulasitiki;
Izici zayo eziyinhloko:
1), sebenzisa i-deformation yepulasitiki ye-workpiece ukucubungula imicu;
2), umpompi unendawo enkulu ephambanayo, amandla aphezulu, futhi akulula ukuphuka;
3), isivinini sokusika singaba phezulu kunesokusika ompompi, futhi ukukhiqiza kuyathuthukiswa ngokufanayo;
4), ngenxa yokucutshungulwa okubandayo kwe-extrusion, izakhiwo zemishini ye-thread surface ngemva kokucutshungulwa ziyathuthukiswa, ama-rough surface aphezulu, namandla entambo, ukumelana nokugqoka, nokumelana nokugqwala kuyathuthukiswa;
5), ukucubungula okungenasici
Amaphutha ayo yilezi:
1), ingasetshenziswa kuphela ukucubungula izinto zepulasitiki;
2), izindleko zokukhiqiza eziphezulu;
Kunamafomu amabili esakhiwo:
1), i-Oil grooveless tap extrusion - isetshenziselwa kuphela izimo zomshini ezimile zembobo eyimpumputhe;
2) Ompompi be-Extrusion abanama-grooves kawoyela - afaneleka kuzo zonke izimo zokusebenza, kodwa ngokuvamile ompompi abancane be-diameter abaklanyelwe ngama-oil grooves ngenxa yobunzima bokukhiqiza;
1. Ubukhulu
1).Ubude obuphelele: Sicela unake izimo ezithile zokusebenza ezidinga ukwelulwa okukhethekile.
2).Ubude be-groove: yonke indlela phezulu
3) Isikwele se-Shank: Izindinganiso ezijwayelekile zesikwele se-shank okwamanje zifaka i-DIN (371/374/376), i-ANSI, i-JIS, i-ISO, njll.
2.Ingxenye enentambo
1) Ukunemba: Kukhethwe ngezindinganiso ezithile zentambo.Intambo yemethrikhi Izinga le-ISO1/2/3 lilingana nezinga le-H1/2/3 elijwayelekile likazwelonke, kodwa kufanele kuqashelwe izindinganiso zokulawula zangaphakathi zomenzi;
2) Ikhoni yokusika: Ingxenye yokusika kampompi yakha iphethini engaguquki kancane.Imvamisa, uma i-cone yokusika iyinde, impilo kampompi iba ngcono;
I-3) Amazinyo okulungisa: dlala indima yokusiza nokuqondisa, ikakhulukazi lapho uhlelo lokuthinta lungazinzile, amazinyo okulungisa amaningi, kukhulu ukumelana nokuthepha;
3. Umtshingo wetshiphu
I-1), i-Groove shape: ithinta ukwakheka nokukhishwa kwezinsimbi zensimbi, futhi ngokuvamile imfihlo yangaphakathi yomkhiqizi ngamunye;
2) I-Rake angle kanye ne-engeli yokusiza: Uma i-engeli yokupompi ikhula, umpompi uba bukhali, okunganciphisa kakhulu ukumelana nokusika, kodwa amandla nokuzinza kwethiphu lezinyo kuncipha, futhi i-engeli yokusiza i-engeli yokusiza;
3) Inombolo yemitshingo: ukwandisa inani lemitshingo kwandisa isibalo sokusika imiphetho, engandisa ngempumelelo impilo kampompi;kodwa-ke, izocindezela isikhala sokukhishwa kwe-chip, esilimaza ukukhishwa kwe-chip;
Thepha okubalulekile
1. Insimbi yamathuluzi: esetshenziswa kakhulu ompompi be-incisor ngesandla, okungasavamile;
2. Insimbi enejubane eliphezulu engena-cobalt: okwamanje isetshenziswa kabanzi njengezinto zompompi, njenge-M2 (W6Mo5Cr4V2, 6542), i-M3, njll., emakwe ngekhodi HSS;
3. Insimbi enesivinini esikhulu ene-cobalt: okwamanje isetshenziswa kabanzi njengezinto zompompi, njenge-M35, M42, njll., enekhodi yokumaka HSS-E;
4. I-powder metallurgy high-speed steel: isetshenziswa njengezinto zompompi ezisebenza kakhulu, ukusebenza kwayo kuba ngcono kakhulu uma kuqhathaniswa nalokhu okubili okungenhla.Izindlela zokuqamba zomkhiqizi ngamunye nazo zihlukile, futhi ikhodi yokumaka ithi HSS-E-PM;
5. Izinto ze-Carbide: ngokuvamile zisebenzisa izinhlayiya ze-ultra-fine kanye namamaki amahle okuqina, ikakhulukazi asetshenziselwa ukwenza ompompi bomtshingo oqondile ukuze kucutshungulwe izinto ze-short-chip, njenge-grey cast iron, i-silicon aluminium ephezulu, njll.;
Ompompi bancike kakhulu ezintweni.Ukukhetha izinto ezisetshenziswayo ezinhle kungathuthukisa ngokwengeziwe amapharamitha wesakhiwo kampompi, kuyenze ifaneleke izimo zokusebenza ezisebenza kahle nezifuna kakhulu, kuyilapho futhi ibe nokuphila okuphezulu.Njengamanje, abakhiqizi abakhulu bampompi banamafekthri abo wezinto ezibonakalayo noma amafomula wezinto ezibonakalayo.Ngesikhathi esifanayo, ngenxa yezinsiza ze-cobalt nezinkinga zamanani, insimbi entsha ye-cobalt-free high-speed steel ikhishwe.
