Mhando nhatu dzeKugadziraCemented Carbide Rods

Kugadzira ndiyo nzira inofambiswa zvakanyanya mukugadzirwa kweakaomeswa alloy, uye ndiyo nzira yakakosha yekuona iyo chaiyo uye inooneka mhando yeakaoma alloy blanks. Ndiyo nzira yekugadzira hupfu husina chinhu nechimiro chaunoda. Zvayo zvinodikanwa ndezvekuva nerimwe simba uye saizi yakatarwa.

1. Precision molding

Precision kudzvanya haifanire kunge iine yakanaka hardware chete, asiwo yakanaka software. Kunyanya, zvinodikanwa kuve ne: high precision press (TPA press), high precision inofa, high performance musanganiswa, maparamendi ekutsikirira chaiwo uye mamwe mamiriro ekutanga.

Precision kudzvanya kunosanganisira: kudzvanya kutenderera, kudzvanya maitiro parameter muchina uye zviyero zvekuverenga, kusarudzwa kwemusanganiswa, kudzvanya kufa sarudzo, mabhoti kusarudzwa, uye kudzvanya mhando, pamwe nekudzorera zvinhu kugadzirisa, nezvimwe.

2. Extrusion kugadzira

Extrusion molding ari kuisa musanganiswa kupinda extrusion humburumbira pashure plasticizing kurapwa, ipapo kuisa anofa pane imwe mugumo extrusion humburumbira pamwe anodiwa makomba pamusoro pemvura vaya vanofa. Extruder inoiswa kune imwe mugumo we extruder cylinder. Kudzvinyirirwa kweiyo extruder kunopfuudzwa kuburikidza neiyo extruder kune musanganiswa, iyo inopfuura nepaburi rinofa uye inova chigadzirwa chakaumbwa.

Zvakanakira zvaro ndezvi: kureba kwechigadzirwa hachibvumirwi muhuwandu, uye iyo yakareba density yakawanda yunifomu. Zvichakadaro, kazhinji ine kuenderera kwekugadzira kwakasimba, kushanda kwakanyanya nemidziyo yakapusa uye kushanda kuri nyore.

3. Cold isostatic pressing

Cold isostatic pressure inobva pane PASCAL's musimboti; iyo yakatsikirirwa poda inonamirwa mune elastic mold ine imwe chimiro uye hukuru, uye yozoiswa muvharo yakavharwa-high-pressure container. Iyo yemvura yepakati inofambiswa mumudziyo kuburikidza ne-high-pressure pombi, uye yepakati inomanikidza zvakaenzanirana pane imwe neimwe nzvimbo ye elastic mold. Upfu muhupfu hwehupfu hunoiswawo pasi pekumanikidzwa kwakaenzana kumativi ese uye chimiro chayo chinodzikiswa zvakaenzanirana kana chaiswa, kuitira kuti hupfu hunoumbwa kuita compact blank ine chimwe chimiro, saizi uye simba rakakwana.

Sintering

Sintering ndiyo yekupedzisira nzira huru mukugadzirwa kwecemented carbide. Chinangwa chekupisa ndechekushandura porous poda compact kuita alloy ine chimwe chimiro uye zvivakwa. Iyo sintering yeakaomeswa alloy yakanyanya kuomarara nekuda kwekuchinja kwemuviri uye kuita kwemakemikari, asi zvakanyanya nekuda kwekuita kwemuviri, senge sintering body densification, carbide zviyo kukura, shanduko ye bonding chikamu chekuumbwa uye kuumbwa kweiyo alloy chimiro.

Iyo yese sintering process inogona kukamurwa kuita nhanho ina:

Waxing pre-burning stage (

Solid phase sintering stage (800 ℃- eutectic tembiricha)

Liquid phase sintering stage (eutectic tembiricha - sintering tembiricha)

Kutonhora nhanho (sintering tembiricha-mukamuri tembiricha)

Kana iwe uchifarira tungsten carbide zvigadzirwa uye uchida rumwe ruzivo uye ruzivo, unogona KUBATA NESU nerunhare kana tsamba kuruboshwe, kana KUTITUMIRA MAIL pazasi peji rino.
