Yam kev lees paub dab tsi yog cov txheej txheem pwm zoo yuav tsum tau ua kom tau raws li? Puas yog koj lub pwm zoo?

Hnub no, kuv xav piav qhia rau koj txog kev lees paub ntawm cov khoom pwm. Peb tsuas yog txheeb xyuas qhov pom, qhov loj thiab cov khoom ntawm cov pwm. Cia peb saib.

1. Pwm zoo li

1. Qhov chaw tsis zoo

Tsis raug tso cai rau ntawm qhov chaw pwm: tsis muaj cov khoom, scorching, dawb saum, kab dawb, ncov, blistering, whitening (los yog tawg los yog tawg), ci cov cim, wrinkles, thiab lwm yam.

2. Weld marks

Feem ntau, qhov ntev ntawm weld marks rau ncig perforations yog tsis ntau tshaj 5 hli, thiab qhov ntev ntawm weld marks rau tshwj xeeb-zoo li tus perforations yog tsawg tshaj li 15 hli, thiab lub zog ntawm weld marks yuav tsum xeem functional Safety test.

3. Txo

Tsis pub shrinkage nyob rau hauv cov cheeb tsam pom tseeb ntawm qhov tsos, thiab me me shrinkage raug tso cai nyob rau hauv inconspicuous cheeb tsam (tsis muaj dents yuav hnov).

4. Flatness

Feem ntau, lub dav hlau unevenness ntawm cov khoom me me yog tsawg dua 0.3mm. Yog tias muaj cov kev cai sib dhos, cov kev cai sib dhos yuav tsum tau ua kom ntseeg tau.

2. Pwm loj

1. Qhov tseeb

Cov duab geometric thiab qhov tseeb qhov tseeb ntawm cov khoom pwm yuav tsum ua raws li cov kev cai ntawm cov pwm qhib qhib kos duab (lossis 3D cov ntaub ntawv). Tsis tas li ntawd, qhov kam rau ua ntau yam ntawm cov pwm yuav tsum ua raws li cov hauv paus ntsiab lus. Piv txwv li, qhov loj ntawm qhov siab siab yog qhov siab tsis zoo, thiab lub qhov loj qhov siab siab yog qhov zoo siab ntev. Yog tias cov neeg siv khoom muaj cov cai tshwj xeeb, cov tuam txhab pwm tuaj yeem hloov kho ntau lawm raws li qhov tseeb.

2. Pwm phab ntsa thickness

Feem ntau, cov phab ntsa thickness ntawm pwm yog muab faib ua ob hom: nruab nrab phab ntsa thickness thiab tsis nruab nrab phab ntsa thickness. Cov phab ntsa tsis yog nruab nrab yuav tsum ua raws li qhov yuav tsum tau ua, thiab raws li cov yam ntxwv ntawm cov pwm, nws kam rau ua yuav tsum yog -0.1mm.

3. Sib npaug degree

Lub plhaub saum npoo thiab lub plhaub hauv qab ntawm cov pwm yuav tsum sib phim zoo kawg nkaus, thiab lawv qhov sib txawv ntawm qhov tsis tuaj yeem siab dua 0.1 hli. Tsis tas li ntawd, lub qhov, shafts, thiab qhov chaw ntawm cov khoom pwm yuav tsum ua tau raws li qhov sib txawv thiab kev siv cov kev cai, thiab tsis muaj khawb.

4. Daim ntawv teev npe

Cov ntawv ntawm lub npe pwm yuav tsum meej, zoo zoo, thiab ua tiav hauv cov ntsiab lus; daim ntawv teev npe yuav tsum tau kho kom ntseeg tau thiab tsis yooj yim rau poob.

5. Lub taub dej txias

Cov khoom siv raw ntawm cov pwm txias dej nozzle yog yas (tus neeg siv khoom muaj lwm yam raws li qhov yuav tsum tau ua), uas yog tsim los ntawm counterbore processing technology. Txoj kab uas hla ntawm lub counterbore feem ntau yog 25mm, 30mm thiab 35mm, thiab cov kev taw qhia ntawm chamfering ntawm lub qhov yog zoo ib yam. Tsis tas li ntawd, qhov chaw teeb tsa ntawm lub taub dej txias yuav tsum ua raws li cov kev cai tsim nyog thiab yuav tsum tsis txhob tawm ntawm qhov chaw ntawm lub hauv paus pwm, thiab cov cim nkag thiab tawm yuav tsum tau cim.

6. Ejection qhov thiab zoo li

Lub ejection qhov loj thiab qhov ntev ntawm cov pwm yuav tsum ua raws li cov kev cai ntawm lub tshuab txhaj tshuaj molding. Tsuas yog cov pwm me me, tsuas yog ib lub chaw tsis tuaj yeem siv rau kev tshem tawm.

3. Pwm khoom thiab hardness

1. Pwm puag khoom

Lub hauv paus pwm yuav tsum yog lub hauv paus pwm uas ua tau raws li cov kev cai, thiab nws cov khoom yuav tsum muaj qee qhov kev hloov pauv ib puag ncig.

2. Kev ua tau zoo

Pwm cores, txav tau thiab ruaj khov pwm inserts, txav tau ntxig, diverter cones, laub rods, lub rooj vag lub tes tsho thiab lwm qhov chaw muaj kev ruaj ntseg zoo thiab corrosion kuj, thiab lawv cov khoom siv siab tshaj 40Cr.

3. Hardness

Lub hardness ntawm molded qhov chaw yuav tsum tsis txhob tsawg tshaj li 50HRC, los yog lub hardness ntawm nto hardening kev kho mob yuav tsum siab tshaj 600HV.

Cov saum toj no yog txhua yam hais txog cov qauv kev lees paub pwm. Kuv vam tias nws yuav pab tau rau sawv daws.
