Kutaura Nezve Kushandiswa Kwesimbi yeTungsten Mukugadzira Molds

---

Iyo danda refuremu mukugadzira, kugadzira inoisa iyo yakajairika kushandiswa kweCr12MoV, nzvimbo yayo iri nyore kugadzira "plot aneurysm clipping", inotungamira kune danda uye akasiyana epamusoro akatambanudzwa mamaki, kuderedza kutakura kwedanda, kuitira kuti kugadzirisa dambudziko iri, kuburikidza nekuedza kwakawanda, takaona kuti tungsten simbi inoshandiswa pakufa, asi kwete kudzivisa pepa rekugadzira uye kuisa "adhesion", kugadzirisa "chirongwa aneurysm clipping", uye tungsten simbi haisi nyore kupfeka, kuvandudza kugadzikana uye hupenyu hwebasa hwefa, iyo yepamusoro yemhando yezvigadzirwa.

Iyo furemu danda (chikamu) chikamu chakakosha cheiyo furemu gungano kuti ive nechokwadi chekuomarara kwefuremu uye kutakura kureba. Nekuenderera mberi kwekuvandudzwa kwemhando yemotokari yese, kunaka kweiyo furemu danda kwave kwakakosha. Kuti udzivise simba remusangano wemapuranga kubva pakuderedzwa nekuda kwekukanganisa kwehutano hwedanda, inodiwa kuvandudza kunaka kwedanda.

Kukanganisa kwemhando yezvikamu uye kuongororwa kwezvikonzero zvavo

(1) Hunhu hurema hwezvikamu. 

Kuomarara kweparutivi kwakakomba, uye maitiro anoratidzwa muTafura 1.

Tafura 1 Scratch yekuongorora zviyero

giredha	Kutonga Kwemitemo
V1	Kukwesha kwakakura kudarika 0.3mm
V2	Kana saizi yakakura kupfuura 0.2mm uye isingasviki 0.3mm, uye nzvimbo yekunhonga ishoma pane kana kuenzana ne100mm.
V3	Kunhonga nhambwe kushoma kana kuenzana ne 0.2mm, nhambwe yekunhonga yakakura kupfuura 0.2mm uye isingasviki 0.3mm ndiyo 100mm kana kupfuura uye yakakwenenzverwa
chitsamba	V2 inogona kuburitswa zvinoenderana neiyo V3 yakajairwa mushure mekunge chikamu chakavharwa chakwenenzverwa, uye nzvimbo yakakwenenzverwa inofanirwa kuve yakatsetseka. Pamusoro pepamusoro peplate yesimbi uye hupamhi kusvika kuhupamhi hwechiyero haisi pasi pe6: 1

Mufananidzo 2 unoratidza maitiro ekushandisa Cr12MoV kugadzira anoisa kugadzira zvikamu.

Mufananidzo 2 unoratidza maitiro ekushandisa Cr12MoV kugadzira anoisa kugadzira zvikamu.

Kuongororwa kwechigadzirwa:
Iyo dhizaini inonyanya kutariswa pamabhendi pamativi ese, uye kudzika kwakadzika ndeye 0.5 ~ 0.9mm.

(2) Zvinokonzera kukanganisa muzvikamu.

Munguva yekugadzira mold yechikamu, nekuda kwehama inotsvedza pakati pepamusoro pechikamu uye pamusoro peiyo mold convex uye concave mold, iyo mold convex, concave mold uye chikamu chinoumba maviri e friction pairs, izvo zvinogadzira zvishoma. yakakura mechanical stress pane yekuonana pamusoro (kunyanya nzira yekugadzira). Kana chikamu chacho chapinda mugomba re mold, chikamu: the concave die mouth), izvo zvinoita kuti twudiki twunhu tudiki twuri twuma friction surfaces twune hurema kana hurema hweplastically, zvichikonzera kusimbaradzwa kana kushoma kwemaatomu ezvisungo zveatomu pamusoro pezviviri izvi. mativi. Nzvimbo yerudzi urwu inonzi cold welding. . Kana iyo friction pairi inofamba ichienderana kune imwe neimwe, nekuti iyo yakanaka maatomu mabhondi ari pamusoro pemativi maviri anosiya kubva kune mumwe kune mumwe, zvinhu zvinotamiswa kubva kune rimwe divi re friction peya kuenda kune imwe nzvimbo, kugadzira simbi bond phenomenon, uye kuunganidza mapfundo. Kana pamusoro peiyo friction pair iri rougher, iyo metal bonding phenomenon inonyanya kuumbwa, izvo zvichaita kuti chikamu chiomerwe.

3 Sarudzo yezvigadzirwa zveiyo die insert uye maitiro eiyo tungsten simbi

3.1 Kusarudzwa kwezvinhu zveiyo yekuisa die

Kuburikidza nechikamu chekuongorora chikanganiso, kusarudzwa kweanoisa kufa kunoita basa rakakosha mukugadzirisa chikamu chekudhonza mamaki. Izvi zvinoda iyo inofa ine yakaderera friction coefficient, yakanyanya kupisa conductivity, uye yakanyanya kuoma. Mushure mekuenzanisa zvinhu, zvinhu zvitatu Ongororo yekushandiswa kwetungsten simbi YG8 yakazosarudzwa. Kuenzanisa kwezvinhu zvitatu kunoratidzwa muTafura 2.

zvinhu	Coefficient yekukweshera	Kupisa kwemafuta (W/m·k)	Kupisa kurapwa kuoma (HRC)	chitsamba
Cr12MoV	0.15 ~ 0.3	45	56-60	Kuoma kwakaderera kusati kwaitwa kupisa, Kuoma kwakawedzera mushure mekurapwa kwekupisa
Beryllium mhangura (CB-2H)	0.006 ~ 0.01	100 ~ 110	42 ~ 48	Hapana chikonzero chekurapa kwekupisa
Tungsten simbi (YG8)	0.005 ~ 0.008	59 ~ 88	69 ~ 82	Hapana chikonzero chekurapa kwekupisa

3.2 Hunhu hwe tungsten simbi

Tungsten simbi ine nhevedzano yezvinhu zvakanakisa zvakadai sekuoma kwepamusoro, kusapfeka, simba rakanaka uye kuomarara, kusapisa kupisa uye kushomeka kwemarara, kunyanya kuomarara kwayo kwakanyanya uye kusapfeka, izvo zvinoramba zvisingachinji kunyangwe patembiricha ye500 ° C. Ichiri nekuoma kwepamusoro pa1,000 ° C.

4 Chengetedzo ye inlay uye kugadzirisa kwe tungsten simbi inoisa

4.1 Inlay ye tungsten simbi inoisa

Kuomarara kwechikamu kunonyanya kuve muarc yedivi, saka zvakasarudzwa kushandisa tungsten simbi chete muarc ye mold. Kuoma kwesimbi ye tungsten yechipiri chete kune diamond, haigoni kugayiwa uye inogona kungogadziriswa nekukuya. Chimiro chinofanira kunge chakanyatsokandwa, uye nzvimbo yakabatana inogadzika nevhiri redhaimani kudzivirira tambo
gomba. Iyo yakakosha concave mold inoiswa yakamisikidzwa pamutumbi wekukanda nepadivi, uye iyo simende carbide yakamisikidzwa mune yakakosha kuisa muchimiro chenjiva groove. Iyi nzira yekugadzirisa inogadzirisa dambudziko rekutadza kudhiraivha uye kudzoreredza maburi mune simende carbide.

4 yakaratidzwa.

4.2 Chengetedzo yekugadzira tungsten simbi inoisa

(1) Nyaya dzinoda kutarisirwa panguva yekucheka nekukuya.

• a. Tungsten simbi inowanzo pwanya uye kona kucheka pasi pesimba uye yakawandisa kugadzirisa mutoro. Inofanira kusimbiswa zvakasimba pane worktable isati yagadziriswa.
• b. Iyo magnetic properties ye tungsten simbi yakaderera zvakanyanya. Usashandise magineti kugadzirisa iyo simende carbide. Ndokumbira ugadzirise nemudziyo wekushandisa. Ndokumbira usimbise zvakare kana workpiece yakasununguka isati yagadziriswa. Kana zvakadaro, gadzirisa workpiece kune kumira kwakasimba.
• c. Iyo yakagadziriswa pamusoro petungsten simbi mushure mekucheka nekugaya ichave yakatsetseka, uye makona akapinza kwazvo, ndapota teerera kuchengetedzwa kana uchibata uye uchishandisa.
• d. Tungsten simbi chinhu chine kuomarara kwakanyanya uye brittleness. Inorambidzwa kurova hard alloy nesimbi nyundo kana ichitya kukanganisa.

(2) Nyaya dzinoda kutariswa panguva yekubuda uye kucheka waya.

• a. Tungsten simbi ine kuoma kwakanyanya uye yakakwirira kupfeka kuramba, uye maitiro ekuvhiya anononoka panguva yekubuda uye kucheka waya.
• b. Tungsten simbi inonyanya kukanganiswa nekutsemuka uye makona mushure mekugadzirwa kwemagetsi, saka ndapota gadzirisa maitiro ekugadzirisa zvinoenderana nemamiriro ekushandisa echigadzirwa.
• c. Tungsten simbi inowanzo putika panguva yekucheka pamhepo, saka ndapota simbisa kuti hapana chakakanganisika pane yakagadziriswa nzvimbo mushure mekugadzirisa usati waenda kune inotevera maitiro.

5 Mhedzisiro yezvikamu mushure mekushandisa tungsten simbi mold

Mushure mekunge kambani yedu yatora tungsten simbi mold:

• (1) Kuomarara padivi pechishandiso kunobviswa sezvakaratidzwa mumufananidzo 5.
• (2) Chiitiko chisingatarisirwi chakawanikwa, uye chakawanikwa kuti makwinya ekunze kwearc akaderedzwa. Izvi zvakaongororwa. Nekuti tungsten simbi ine kuomarara kwepamusoro uye kunaka kwakatsvuka kuoma, inogona kusvika 900～1,000℃, uye haizokanganisika kana ichinge yachengetwa pa60HRC. Nenzira iyi, kunyangwe kana zvinhu zvichiyerera, chikamu chinoburitsa elastic uye epurasitiki deformation, inozokanganisa kupinza. Nekunetseka kwakasimba, gaka riri pakati pe convex uye concave molds harizoshanduki, uye kushandiswa kwakasimba kwekunze kwearc ye workpiece kunogona kuderedza makwinya.

6 ekupedzisa mazwi

Kubva pakagamuchirwa tungsten simbi molds, kambani yedu yakavandudza kunaka kwezvikamu, yakasimbisa kugadzikana kwemhando yezvikamu, yakawedzera hupenyu hwemuumbi, uye yakawedzera kutenderera kwekugadziriswa kwe mold, nekudaro ichidzikisa mutengo wekugadzira. uye kugadzirisa dambudziko rezvikamu zvakakora zveplate. Iyo wrinkle strain munda inopa chinhu chitsva.
