Qhov txawv ntawm Pub- hom, Los ntawm - hom thiab Wide Wheel Centerless Sib Tsoo
Apr 14, 2026
Raws li lub hauv paus ntsiab lus ntawm precision manufacturing thiab cov yam ntxwv tshwj xeeb ntawm centerless sib tsoo, daim ntawv no muab cov ncauj lus kom ntxaws tsom xam ntawm qhov sib txawv ntawm pub- hom, los ntawm - hom, thiab dav - log centerless sib tsoo technologies.
Txawm hais tias "wide log" yog technically cais raws li lub tshuab configurations los yog log specifications es tsis pub txoj kev (xws li Infeed los yog Throughfeed), lawv feem ntau categorized nyias vim hais tias lawv txiav txim siab qhov kev siv ntawm kev sib tsoo txheej txheem (uas feem ntau sib tshooj nrog rau txoj kev pub mis los yog kev mob siab rau throughfeed ua hauj lwm). Cov kev sib piv hauv qab no yuav pab koj paub qhov txawv ntawm lawv.
1. Centerless throughfeed sib tsoo
Qhov no yog txoj kev siv ntau tshaj plaws los tsim cov khoom loj ntawm qhov yooj yim cylindrical.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm: Lub workpiece yog muab tso rau ntawm lub worktable hniav, nyob nruab nrab ntawm lub sib tsoo log thiab regulating log. Lub regulating log yog inclined ntawm ib tug me ntsis lub kaum sab xis (feed lub kaum sab xis), tsim ib tug "helical kab" nyhuv uas ua rau cov workpiece axially mus rau hauv lub sib tsoo cheeb tsam.
Cov yam ntxwv tseem ceeb: Cov khoom siv txuas ntxiv txav ntawm ib sab ntawm lub tshuab mus rau lwm qhov. Lub log sib tsoo feem ntau siv cov kab sib tsoo (lossis me ntsis yas sib tsoo) tsis muaj radial txav (los yog qeeb heev) thaum lub sij hawm sib tsoo.
Lub hom phiaj pej xeem:
- Yooj yim, upright cylindrical Cheebtsam (pins, rods, tubular structures).
- Loj - ntau ntau lawm.
- Cheebtsam yam tsis muaj lub xub pwg nyom lossis cov duab sib txawv.
Qhov zoo: Lub sijhawm voj voog ceev heev; zoo ib yam nto tiav; yooj yim automation ntawm loading thiab unloading ua hauj lwm.
Disadvantages: Tsis tuaj yeem zom cov khoom nrog lub taub hau, lub xub pwg nyom, lossis cov geometry nyuaj.
2. Infeed Centerless Sib Tsoo (Immersion Sib Tsoo)
Txoj kev no yuav tsum tau siv thaum ib feem ntawm qhov geometry obstructs nws txoj kev hla lub log.
Lub hauv paus ntsiab lus ua haujlwm: Lub workpiece yog muab tso rau ntawm lub worktable hniav. Lub log sib tsoo (los yog lub log regulating) txav radially (perpendicular mus rau lub workpiece nto) kom ua tiav "txiav" ntawm lub workpiece. Tsis siv axial pub; lub workpiece tseem ruaj khov thaum lub sij hawm sib tsoo.
Cov yam ntxwv tseem ceeb: Lub log sib tsoo feem ntau yog profiled (zoo li tus) kom phim lub workpiece daim ntawv. Thaum lub sij hawm qis - kev ua haujlwm siab, nws tuaj yeem ua kev sib tsoo tag nrho ntev lossis cov chaw tshwj xeeb hauv ib qho dhau los.
Lub hom phiaj pej xeem:
- Cheebtsam nrog lub xub pwg nyom, taub hau, los yog complex contours (conical, spherical).
- Cov khoom uas luv dhau los yog tsis yooj yim heev tsis tuaj yeem ua machined siv lub tshuab pub noj tsis tu ncua.
- Ntau txoj kab uas hla tuaj yeem ua hauv av ib txhij ntawm tib ntu.
Qhov zoo: Muaj peev xwm sib tsoo cov duab nyuaj; exhibits high precision nyob rau hauv tej qhov chaw.
Qhov tsis zoo: Feem ntau qeeb dua li txoj kev noj zaub mov (lub sij hawm lub voj voog nrog rau kev thauj khoom, nias, nyob, thiab thim rov qab); yuav tsum muaj ntau txoj kev siv disc trimming.
3. Dav - log Centerless sib tsoo
Qhov no yog hais txog kev siv lub log sib tsoo nrog qhov dav dav dua li tus qauv tus nqi, uas yuav cuam tshuam rau kev sib tsoo lub tswv yim.
Lub hauv paus ntsiab lus ua haujlwm: Lub log dav (feem ntau yog 300 hli txog 600 hli lossis loj dua) tuaj yeem npog thaj tsam loj dua ntawm qhov chaw ua haujlwm. Cov cuab yeej no tuaj yeem siv tau ob txoj hauv kev:
- Txoj kev pub dav dav: Haum rau cov khoom ua haujlwm ntev (xws li cov hlua ntev lossis cov raj). Lub log dav tsim kom zoo sib tsoo thoob plaws tag nrho ntev ntawm lub workpiece thaum pub mis, txawm tias thaum muaj me ntsis wobbling los yog lub workpiece nkag mus rau ntawm lub inclined lub kaum sab xis.
- Tus nqi pub dav dav: Lub log dav siv rau kev sib tsoo cov ntu ntev ntawm qhov chaw thaum lub sij hawm qis qis, lossis rau kev sib tsoo ntau qhov chaw sib tsoo ntawm ib sab.
Cov yam ntxwv tseem ceeb: Qhov chaw sib txuas loj ntawm lub log thiab cov khoom ua haujlwm tso cai rau kev sib tsoo ntawm kev sib tsoo quab yuam thiab cua sov hla thaj tsam dav.
Lub hom phiaj pej xeem:
- Ntev axis xav tau siab ncaj (cylindricity).
- Kev tshem tawm cov khoom siab (siab - txoj kev sib tsoo ceev).
- Ib txhij zom cov pawg ntawm cov khoom nyias (xws li, ntxhua khaub ncaws).
Qhov zoo: txo lub log hnav (nrog kev hnav tsis sib xws); Txhim kho cylindricality ntawm cov khoom ntev; Txhawb "siab - kev sib tsoo" (nrog rau kev tshem tawm cov khoom siab).
Disadvantages: Yuav tsum muaj zog dua txhua yam thiab horsepower; ua kom sov ntau dua (yuav tsum tau ua kom txias txias); yuav tsum tau siv lub log tsheb ntev dua.
