Ma valve osindikizira pamwamba akupera ndi kusonkhanitsa Chogwirira cha vavu ndi penti yapamanja

Ndi njira yomaliza yopangira, imatha kupanga magawo kuti apeze kulondola kwapamwamba kwambiri, kulondola kwazithunzi ndi kumalizidwa kwapamwamba, koma sangathe kusinthana pakati pa kulondola kwapamwamba. Chida chogayira chikuyenera kukwaniritsa ziwiri izi: ① zosavuta kuyika tinthu tating'onoting'ono ta abrasive ② zimatha kukhalabe ndi mawonekedwe a geometric mwatsatanetsatane kwa nthawi yayitali. Choncho, ambiri ntchito zipangizo zofewa kuposa workpiece kuchita kafukufuku zida, ambiri ntchito imvi kuponyedwa chitsulo. Pokonzekera msonkhano wa valve, thupi la valve nthawi zambiri limagwiritsidwa ntchito ngati zigawo zofotokozera, molingana ndi dongosolo lomwe likufotokozedwa pamsonkhanowo, ndipo njirayo ikuchitika. Pamaso pa msonkhano, m'pofunika kufufuza ngati mbali zachotsedwa ndi kutsukidwa.
Vavu kusindikiza pamwamba akupera
Choyamba, akupera mfundo zofunika ndi zida
(I) Mfundo Zoyambira:
Ndi njira yomaliza yopangira, imatha kupanga magawo kuti apeze kulondola kwapamwamba kwambiri, kulondola kwazithunzi ndi kumalizidwa kwapamwamba, koma sangathe kusinthana pakati pa kulondola kwapamwamba.
Akupera, chida ndi workpiece pamwamba zimagwirizana, pakati kudzaza abrasives, pamene chida pamodzi pamwamba olowa, zovuta zolimbitsa thupi pakati pa mbali ziwiri za abrasive grits pamwamba kutsetsereka kapena kugudubuza, mbali ya abrasive ndi ophatikizidwa kapena sessile pamwamba chida, ndi kudulidwa workpiece pamwamba ndi woonda kwambiri wosanjikiza zitsulo, ndi otukukira pachimake pachimake pa workpiece choyamba akupera, pang'onopang'ono kukwaniritsa chofunika padziko chofunika.
Kuti apange yunifolomu yopera pamwamba, njira yoyendayenda ya mfundo iliyonse pa chogwiritsira ntchito kupita ku chida chopera iyenera kukhala yofanana momwe zingathere, kotero kuti kayendetsedwe ka kayendetsedwe kake kayenera kusinthidwa nthawi zonse.
Kuthamanga kwachangu, kumapangitsa kuti ntchitoyo ikhale yowonjezereka, koma ngati ili yochuluka kwambiri, imapangitsa kuti ntchitoyo ikhale yotentha komanso imakhudza kulondola kwa geometric. Panthawi imodzimodziyo, tiyenera kusamala kuti tisamapanikizike kwambiri pamtunda, apo ayi kungayambitsenso kutentha.
Chifukwa akupera ndi yosalala processing, kudula kuchuluka ndi kochepa kwambiri, kotero mu akhoza kuonetsetsa kuchotsa processing kufufuza njira yomaliza, maziko a kukonza workpiece geometry cholakwika, ang'onoang'ono pogaya malipiro, bwino.
(2) Zida zopera
Chida chogayira chikuyenera kukwaniritsa ziwiri izi: ① zosavuta kuyika tinthu tating'onoting'ono ta abrasive ② zimatha kukhalabe ndi mawonekedwe a geometric mwatsatanetsatane kwa nthawi yayitali. Choncho, ambiri ntchito zipangizo zofewa kuposa workpiece kuchita kafukufuku zida, ambiri ntchito imvi kuponyedwa chitsulo.
Abrasive ndi chisakanizo cha zinthu ndi abrasive madzimadzi. Zomwe zimagwiritsidwa ntchito nthawi zambiri ndi corundum (alumina), silicon carbide, boron carbide, chromium oxide, iron oxide ndi diamondi ufa, coarse abrasive akagwiritsidwa ntchito.
Madzi akupera amagwiritsidwa ntchito kusintha abrasive, ndipo amasewera mafuta, kuziziritsa ndi makutidwe ndi okosijeni.
Awiri, ma valve osindikiza pamwamba akupera
(a) kugaya pamanja
Kupukuta pamanja ndikosavuta, koma kutsika kwachangu, kusakhala bwino, koyenera mabizinesi ang'onoang'ono ndikukonza.
1. Kupera pamanja kwa kusindikiza pamwamba pa thupi la valve
Kugwiritsiridwa ntchito kwa dzenje lalikulu la dimba zooneka ngati akupera chida amaikidwa pa kusindikiza pamwamba pa valavu thupi patsekeke, ndiyeno chogwirira yaitali ndi mutu lalikulu ntchito kuyendetsa mbale akupera kwa akupera kayendedwe. Pali bwana wagawo la dimba kapena yambitsani mbale ya kutentha pa mbale yogayo kuti chida chopera zisatsegule posindikiza.
Musanagaye, chida choperacho chiyenera kutsukidwa, chophimbidwa ndi abrasive, ndipo chida chopera chiyenera kuikidwa pamtunda wosindikizira, choyamba mutembenuzire mozungulira 180 ° ndiyeno motsatira 90 °, mobwerezabwereza, tcherani khutu ku yunifolomu ndi mphamvu yoyenera. pamene akupera, ndipo nthawi zonse kuwonjezera abrasive.
2, valavu mbale, vavu chimbale ndi mbali zina kusindikiza pamwamba akupera
Kugwiritsa ntchito mbale akupera kwa Buku akupera, choyamba pa mbale wogawana TACHIMATA ndi wosanjikiza wothandizila akupera, workpiece Ufumuyo mbale, kwa mbali imodzi kuchita kasinthasintha ndi kuchita liniya kayendedwe kapena chithunzi 8 kayendedwe.
Mtundu wa PAINT wa chogwirira cha valve ndi gudumu lamanja umasiyana malinga ndi kusindikiza pamwamba.
Pentani CHINONGA CHA VALVE NDI CHANJA CHANJA. Onani TABULO LOTSIRIZA LA UTUNDU WA PEnti WA NTCHITO yosindikizira
