Momwe mungasankhire tsamba la simenti ya carbide?

Carbide insert ndi chida chomwe chimagwiritsidwa ntchito kwambiri pamakina othamanga kwambiri. Zinthu zamtunduwu zimapangidwa ndi zitsulo za ufa ndipo zimakhala ndi tinthu tating'ono ta carbide ndi zomatira zachitsulo zofewa. Pakadali pano, pali mazana amitundu yosiyanasiyana ya carbide yopangidwa ndi simenti ya WC, yomwe ambiri amagwiritsa ntchito cobalt monga binder, faifi tambala ndi chromium zilinso zinthu wamba zomangira, ndi zinthu zina za aloyi zitha kuwonjezedwa.

Kusankhidwa kwa tsamba la simenti ya carbide: Kutembenuza tsamba la simenti ya carbide ndiye njira yayikulu yopangira ukadaulo wopangira simenti, makamaka mumakampani opanga makina olemera, kusankha chida ndikofunikira kwambiri. Malinga ndi zida zosiyanasiyana zopangira, poyerekeza ndi makina wamba, kutembenuka kolemetsa kumakhala ndi mawonekedwe akuya kwakukulu, kuthamanga otsika komanso kuthamanga kwapang'onopang'ono. Chilolezo cha makina kumbali imodzi chimatha kufika 35-50 mm. Kuonjezera apo, chifukwa cha kusakwanira bwino kwa workpiece, kugawidwa kosiyana kwa chiwerengero cha zida zamakina ndi kusalinganika kwa magawo ndi zinthu zina, kugwedezeka kwa machining allowance kumapangitsa kuti kusinthasintha kwamphamvu kuwononge nthawi yambiri ya foni. ndi nthawi yothandizira. Choncho, kuti pokonza mbali zolemetsa ndi kusintha zokolola kapena kugwiritsa ntchito mlingo wa zipangizo makina, tiyenera kuyamba ndi kuonjezera makulidwe ndi mlingo chakudya cha kudula wosanjikiza. Tiyenera kulabadira kusankha kudula magawo ndi masamba, kusintha kapangidwe ndi geometry wa masamba, ndi kuganizira zinthu masamba. Mphamvu makhalidwe, motero kuonjezera kudula magawo ndi kuchepetsa kwambiri ntchito nthawi.

Zida zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo zitsulo zothamanga kwambiri, carbide ya simenti, zoumba, ndi zina zotero. Kuzama kwakukulu kumatha kufika 30-50mm, ndipo malipirowo ndi osagwirizana. Pali wosanjikiza wowumitsidwa pamwamba pa workpiece. Mu gawo la makina ovuta, kuvala kwa tsamba kumachitika makamaka ngati kuvala kwa abrasive Kuthamanga kwachangu kumakhala 15-20 m / min. Ngakhale liwiro mtengo ndi agglomeration pa Chip, kutentha mkulu wa kudula kumapangitsa kukhudzana mfundo pakati Chip ndi kutsogolo chida pamwamba mu madzi boma, motero kuchepetsa mikangano ndi inhibiting ndi agglomeration wa m'badwo woyamba wa tchipisi. Zida za tsamba ziyenera kukhala zosavala komanso zosagwira. Tsamba la ceramic lili ndi kuuma kwakukulu, koma mphamvu yopindika yotsika komanso kulimba kocheperako. Sikoyenera kutembenuka kwakukulu ndipo ili ndi m'mphepete mwake. Simenti carbide ali ndi mndandanda wa ubwino monga "high kuvala kukana, mkulu kupinda mphamvu yopindika, zabwino zotsatira kulimba ndi mkulu kuuma", pamene mikangano coefficient wa simenti carbide ndi otsika, amene angathe kuchepetsa kudula mphamvu ndi kudula kutentha, ndi bwino kwambiri durability. wa bla. Oyenera makina okhwima a zida zolimba kwambiri komanso kutembenuka kolemera. Ndi chisankho chabwino chotembenuza zida zamasamba.

Kupititsa patsogolo kuthamanga kwa zoyika za simenti zama carbide mumakina olemera ndi chimodzi mwazinthu zofunika kwambiri pakuwongolera magwiridwe antchito ndikufupikitsa nthawi yopanga. Pochita izi, kuchuluka kochulukirapo kumadulidwa mu zikwapu zingapo, ndipo kuya kwa sitiroko iliyonse kumakhala kochepa kwambiri. Kudula kwa tsamba kumatha kupititsa patsogolo kuthamanga kwachangu, motero kuwongolera magwiridwe antchito, kukulitsa moyo wautumiki, ndikuchepetsa mtengo ndi phindu.
