Cov pwm dav dav muab faib rau hauv nruab nrab phaj, pwm sab sauv, pwm qis, kev taw qhia kev tsheb nqaj hlau, qis pwm puag, thiab lwm yam. Cov pwm no muaj zog versatility, thiab feem ntau ntawm cov txheej txheem tuaj yeem ua tiav.
Cov pwm sib txawv yuav tsum tau ua cov txheej txheem sib txawv. Ua ntej tshaj plaws, peb yuav tsum nkag siab txog kev ua haujlwm ntawm cov cuab yeej siv tshuab thiab cov pwm ua ntej peb tuaj yeem xaiv cov pwm uas sib phim.
Lub tshuab cuab yeej tsis muaj xws li: mob stroke, lub peev xwm ua, qhib qhov siab, nruab nrab phaj hom, thiab lwm yam .; pwm tsis muaj xws li: sab sauv kov hom (nrog rau nruab nrab phaj), siab tonnage (siab tshaj plaws dabtsi yog khoov siab), thiab lwm yam.;
A hais txog kev xaiv cov tshuab tsis
1. Kev xaiv pwm qhov siab
Stroke (mm)=qhov siab ntawm qhov qhib - qhov siab ntawm nruab nrab phaj - qhov siab ntawm lub puab pwm - qhov siab ntawm qis pwm puag - (qhov siab ntawm qis pwm - 0}.5V ntxiv rau t) t yog daim ntawv thickness (mm )
Thaum xaiv lub hauv paus pwm qis, nws yuav tsum tau muab sau tseg tias lub hauv paus pwm qis muaj ntau qhov siab, thiab cov pwm pwm ntawm qhov siab sib txawv yog siv los ua kom sib txawv.
Cov pwm sib txawv tuaj yeem siv tau kom tau txais cov pwm sib txawv ua ke qhov siab rau kev ua cov khoom sib txawv.
B txog kev xaiv pwm tsis
1. Daim ntawv ntawm sab sauv pwm kov
Tus kov ntawm lub pwm sab sauv muaj 3 hom kom phim cov phaj nruab nrab sib txawv
2. Upper puab puab
Feem ntau siv cov qauv puab sab sauv pwm yog:
3. Lub taub hau R lub kaum sab xis thiab lub kaum sab xis ntawm lub pwm sab saud. Feem ntau siv R cov kaum sab xis ntawm cov pwm sab saud yog:
(1) 0.2R (2) 0.6R (3) 0.8R (4) 1.5R (5) 3.0R
Xaiv cov lus qhia tsim nyog R: feem ntau siv R0.6 hauv qab 3 hli.
Lub kaum sab xis ntawm cov txheej txheem sab saud yog: 90 degrees, 88 degrees, 86 degrees, 60 degrees, 45 degrees, 30 degrees; lwm.
Lub kaum sab xis ntawm cov pwm yuav tsum me dua li lub kaum sab xis ua. Piv txwv li, yog tias peb khoov lub workpiece mus rau 90 degree, peb siv 88 degree nrog lub kaum sab xis pwm.
4. Daim ntawv pwm qis
Cov pwm qis dav dav muaj qhov sib txawv ntawm ib leeg V thiab ob chav V, thiab muaj kev faib thiab tag nrho cov seem hauv ob hom no. Cov pwm sib txawv yog tsim rau cov kev xav tau sib txawv.
Feem ntau hais lus, ib leeg-V pwm yog ntau yam ntau dua li ob-V pwm, thiab cov pwm sib cais yog ntau yam ntau dua li cov pwm tag nrho. Cov pwm qis siv los ntawm peb lub tuam txhab feem ntau yog ob npaug V thiab triple V.
5. Pwm qis V dav, V zawj lub kaum sab xis
Kev sib raug zoo ntawm kev xaiv V groove ntawm qis tuag thiab cov khoom thickness (T):
Lub kaum sab xis ntawm V groove ntawm cov pwm qis yog zoo ib yam nrog cov pwm sab saud.
