Kev sib koom ua ke ntawm cov ntsiab lus tseem ceeb ntawm kev khoov thiab kev tsim cov pwm kho vajtse
Tso lus
Nyob rau hauv peb cov ntaub ntawv, lub positioning pins yog tag nrho cov nyob rau ntawm lub stripper phaj, thiab qhov siab ntawm lub forming insert yuav tsum siab tshaj qhov ntev ntawm lub positioning pin. Thaum tsim tsis muaj qhov chaw, nws txoj hauj lwm nyuaj rau lav.
Txawm li cas los xij, peb yuav tsum paub tias yog tias koj qhov punch xovxwm raug tsis zoo heev (parallelism, crankshaft thermal expansion thiab contraction, ncej clearance), yog hais tias nws yog upward forming los yog "Z" forming, lub stability ntawm lub stripper phaj forming yog ntau ntau dua li ntawm cov insert (feem ntau tsis siv).
Insertion haum
(1) Standard haum
Ntawd yog, qis tuag ntxig R=qaum tuag punch R - khoom thickness T
Qhov zoo: Kev sib sau yog qhov ruaj khov, haum rau cov xwm txheej nrog T me me (me me tuag tshem tawm, zoo sab sauv thiab qis haum qhov tseeb), tsis tshua muaj kev cuam tshuam los ntawm kev hloov pauv hauv kev tuag tshem tawm.
Qhov tsis zoo: Thaum T loj (piv txwv li, 0.5mm), lossis cov khoom siv tawv, nws tsis yooj yim rau kev tsim, thiab lub caij nplooj ntoos hlav loj.
Qis tuag ntxig R tsim: Raws li tus nqi xav tau ntawm lub davhlau ya nyob twg puag ncig, lub caij nplooj ntoos hlav tuaj yeem tsis pom zoo. (2) Pre-forming + Forming Method Design Qhov chaw nyob deb tuaj yeem muab tau los ntawm kev sib raug zoo saum toj no raws li 3.1415 * R / 4 + tus nqi kho (723TAIL ntev txhim kho, STANDOFF sim molding)
(3) Qhov sib txawv ntawm ob qhov haum
Siv 90℃ua piv txwv
Qhov thib ob fold thiab thawj zaug yuav tsum tau ua tib zoo txuas.
Tus nqi kho yog rau kev siv nkaus xwb:
Brass / Tin Bronze 0.20mm, CON'T dav li ntawm 0.05mm, B / L dav 0.05 ~ 0.15mm, Hlau 0.30mm thiab siab dua: 0.10 ~ 0.20mm, yuav tsum tau txiav txim raws li qhov tseeb
● Qhov nruab nrab qhov nrug yuav cuam tshuam rau cov duab thiab qhov nyuaj ntawm kev tsim (xws li qhov thib ob fold)
●Nws yog ib qho tsim nyog los xyuas kom meej tias tsis muaj ob "R", thiab xyuas kom meej tias 90℃tuaj yeem ua tiav tau yooj yim
●Thaum tsim qauv, thawj zaug xav txog cov khoom tuab / dav ntawm lwm qhov uas tau tsim, thiab qhov thib ob xav txog qhov khoov R / dabtsi yog khoov qhov siab.
Tsis txhob ua raws li cov cai, thiab yog tias tsim nyog, qhov qis tuag ntxig yuav tsum tau tsim kom tsawg dua 90℃los them rau qhov loj dua springback hauv qhov tseeb. Yog vim li cas: Vim hais tias muaj qhov nruab nrab qhov nruab nrab ntawm qhov chaw ntawm ② (raws li qhia hauv daim duab), qhov ntev ntawm kev sib sau yog luv dua thiab yooj yim rau daim ntawv, thaum taw tes ① yooj yim rau daim ntawv tab sis muaj qhov loj dua.
Kev daws:
1. Ntxiv ib qho protrusion ntawm ① txhawm rau ua kom cov nyhuv dabtsi yog khoov.
2. Ntxiv ib qho sab nraud rau qhov kev sib tsoo ntawm ② rau kev kho.
1. Kab lus no tham txog peb txoj kev khoov: downward dabtsi yog khoov, upward dabtsi yog khoov, thiab "Z" zoo li tus tsim.
2. Downward dabtsi yog khoov tsis haum rau kev sib sau ncaj qha nrog lub phaj stripper: nws tsis ua raws li tus txheej txheem ntawm thawj qhov chaw, nias, thiab tom qab ntawd khoov, ua rau deformation tsis ua haujlwm.
3. Qhov zoo thiab qhov tsis zoo ntawm tus qauv haum thiab ntau dhau R haum, thiab qhov sib txawv ntawm cov khoom deformation kev ntxhov siab. (Kev ruaj ntseg, kev nyuaj siab, kev nyuaj siab deformation ntau thiab degree.)
4. Siv cov kev soj ntsuam cov lus tsa suab, ob qho -theem (thaum lub sijhawm txav thiab thaum sib cuag) deformation txoj kev xav thaum khoov tau pom, qhia qhov tsim nyog ntawm cov punch.
5. Rau 90℃txoj kev tsim, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qhov thib ob fold tsis tas yuav rov ua dua 90℃tsim los ntawm thawj zaug, qhov tseem ceeb ntawm qhov chaw nruab nrab ntawm qhov kev tsim, thiab cov yam ntxwv uas yuav tsum tau xav txog hauv kev tsim. 6. Thaum tsim "Z" zoo nyob rau hauv ib qho chaw nres tsheb, tshwj xeeb yuav tsum tau them rau qhov tshwm sim ntawm "tsis sib xws dabtsi yog khoov thiab tsim cov kev ntsuas" yuav tsum tau ua kom zoo.
