Nwuo imewe na ịnwụ nkedo usoro nke zinc alloy die nkedo

Oge: 2020-12-17 Hits: 264

Nhazi geometric maka njikwa elu elu nke ihe nkedo zinc alloy die

 

Na imewe nke zinc alloy nkedo geometry, dị ka o kwere omume zere kpuru oghere omimi concave na ndị ọzọ na owuwu, ya mere, na imewe akụkụ, adịghị emetụta ọdịdị na ojiji nke akụkụ, drainage usoro oghere adaba ngwọta, gas. N'ụzọ dị otú a, ngwọta plating nwere ike na-arụ ọrụ nke ọma plated na mmetọ ogo nwere ike ibelata.

 

Nwuo imewe na ịnwụ nkedo usoro nke zinc alloy die nkedo

 

N'elu nke zinc alloy die nkedo bụ akwa oyi akwa nke nwere ọkpụrụkpụ nke ihe dịka 0.1 mm, akụkụ nke ime bụ ihe owuwu porous. Na usoro nke ịnwụ imewe na ịnwụ nkedo, elu nke workpiece kwesịrị ịdị nro dị ka o kwere mee, na ntụpọ nkedo dị ka mgbawa, ihe ọkụkụ, oghere oyi, burr na burr kwesịrị ibelata.

 

Ya mere, ọ dị mkpa iji rụọ ọrụ nhicha. N'oge a, a ga-ezere elu nke oke oyi akwa, ka ị ghara ikpughe matriks porous, na-akpata ihe isi ike na electroplating na-emetụta àgwà nke electroplating. A na-ejikarị ihe ntọhapụ eme ihe na nkedo zinc alloy die. Ekwesịrị itinye nlebara anya n'iji ihe ntọhapụ na mwepu.

 

Nhọrọ ihe nkedo nke zinc alloy die

 

Ihe ndị a na-ejikarị zinc alloy bụ: 2znal43, 2znal41, 2znal40.5, 2znal4, ụdị znal925 na znal903 a na-ejikarị eme ihe, mana znal903 dị mma karịa znal925.

 

Tụkwasị na nke ahụ, a na-ejikarị akụkụ nke ihe nkwụghachi azụ eme ihe na nkedo anwụ, a ghaghị ịchịkwa oke na 15%, ọkacha mma karịa 20%. N'ihi na ọ dị mfe iji doped na ihe ndị ọzọ (dị ka silicon), adhesion nke mkpuchi na-emetụta. Maka nkedo nwere nzaghachi ndị ọzọ, ọ ka mma iji hydrofluoric acid maka ọgwụgwọ ịgbalite n'oge electroplating.

 

Nyocha oghere nke ihe nkedo zinc alloy die tupu eletrọnịkị

 

(1) Ọdịdị: lelee ma enwere mgbawa, mgbawa, ncha, oghere na ntụpọ ndị ọzọ dị njọ n'elu oghere ahụ. Iji chọpụta oke ntụpọ ndị a, ọ bụrụ na enwere ike iwepụ ha site na nrụnye igwe (polishing, polishing, etc.), usoro egweri nwere ike ịba ụba.

 

(2) Nyocha ihe: lelee ọkwa nke zinc alloy, ghọta oke nke ihe eweghachiri, lelee ogo akụkụ nkedo anwụ, tinye workpiece na oven na 100 ~ 110. maka 30min, wee lelee ma elu ọ na-apụta.
