1. Sarudza zvinoenderana nepombi kushivirira zone
Matepi emuchina wepamba akanyorwa nekodhi yenzvimbo yekushivirira yepitch dhayamita: H1, H2, uye H3 zvichiteerana inoratidza nzvimbo dzakasiyana dzenzvimbo yekushivirira, asi kukosha kwekushivirira kwakafanana. Iyo yekushivirira nzvimbo kodhi yemapombi emaoko iH4, kukosha kwekushivirira, pitch uye kona kukanganisa kwakakura kupfuura matepi emuchina, uye zvinhu, kurapwa kwekupisa uye maitiro ekugadzira hazvina kunaka sematepi emuchina.
H4 inogona kusamakwa sezvinodiwa. Iwo emukati shinda yekushivirira magiredhi anogona kugadziriswa netap pitch tolerance zone ndeaya anotevera: Iyo tap tolerance zone code inoshanda kune yemukati shinda yekushivirira zone mamakisi H1 4H, 5H; H2 5G, 6H; H3 6G, 7H, 7G; H4 6H, 7H Mamwe makambani anoshandisa matepi Akatorwa kunze kwenyika anowanzo cherechedzwa nevagadziri veGerman se ISO1 4H; ISO2 6H; ISO3 6G (yepasi rose chiyero ISO1-3 yakaenzana neyakajairwa yenyika H1-3), kuitira kuti tepi yekushivirira zone kodhi uye inogadziriswa yemukati shinda yekushivirira zone zvese zvakaMaka.
Kusarudza mwero weshinda Parizvino pane matatu akajairwa zviyero zveshinda dzakafanana: metric, imperial, uye yakabatana (inozivikanwawo seAmerica). Metric system ishinda ine zino profile angle yemadhigirii makumi matanhatu mumamilimita.
2. Sarudza maererano nemhando yepombi
Zvatinowanzo shandisa ndezvi: matepi enyere dzakatwasuka, matepi enyere inotenderera, matepi epiral point, matepi eextrusion, imwe neimwe iine zvayakanakira.
Mapombi enyere akatwasanuka ane simba rakasiyana-siyana, kuburikidza neburi kana kuti kwete-kuburikidza neburi, simbi isina ferrous kana simbi inogona kugadziriswa, uye mutengo ndiwo wakachipa. Nekudaro, iyo pertinence zvakare yakashata, zvese zvinogona kuitwa, hapana chakanakisa. Chikamu chekucheka koni chinogona kuva nemazino maviri, mana, uye matanhatu. Iyo pfupi koni inoshandiswa kune isiri-kuburikidza nemakomba, uye iyo refu koni inoshandiswa kuburikidza nemakomba. Chero bedzi gomba rezasi rakadzika zvakakwana, koni yekucheka inofanira kuva yakareba sezvinobvira, kuitira kuti kune mazino akawanda anogovera mutoro wekucheka uye hupenyu hwebasa hurefu.
Spiral nyere matepi akanyanya kukodzera kugadzirisa asiri-kuburikidza negomba tambo, uye machipisi anoburitswa kumashure panguva yekugadziriswa. Nekuda kweiyo helix angle, iyo chaiyo yekucheka rake angle yepombi inowedzera nekuwedzera kweiyo helix angle. Chiitiko chinotiudza: Pakugadzirisa simbi, helix angle inofanirwa kuve diki, kazhinji kutenderera 30 madhigirii, kuve nechokwadi kusimba kwemazino anotenderera. Nekugadzirisa simbi dzisina-ferrous, iyo helix angle inofanira kuva yakakura, iyo inogona kunge yakapoteredza 45 degrees, uye kucheka kunofanira kunge kwakanyanyisa.
Iyo chip inoburitswa kumberi kana shinda ichigadziriswa nepoint tap. Yayo yepakati saizi dhizaini yakakura, iyo simba iri nani, uye inokwanisa kumira akakura ekucheka masimba. Mhedzisiro yekugadzira simbi dzisiri-ferrous, simbi isina tsvina, uye simbi yeferrous yakanaka kwazvo, uye iyo screw-point taps inofanirwa kushandiswa zvakanyanya kune kuburikidza-gomba shinda.
Extrusion matepi anonyanya kukodzera kugadzirisa simbi dzisina-ferrous. Yakasiyana nemusimboti wekushanda wematepi ekucheka ari pamusoro, inoburitsa simbi kuti iite deform uye kugadzira tambo dzemukati. Iyo yakawedzerwa yemukati shinda yesimbi fiber inoenderera, ine yakakwirira tensile uye kugera simba, uye yakanaka pamusoro roughness. Zvisinei, zvinodikanwa zvegomba rezasi repombi yeextrusion zvakakwirira: zvakakurisa, uye huwandu hwesimbi yepasi idiki, zvichikonzera mukati Iyo dhayamita yeshinda yakakura uye simba harina kukwana. Kana iri diki, simbi yakavharirwa uye yakaburitswa haina kwainoenda, zvichiita kuti pombi iparare.
