Ngwa nke EDM Graphite Electrode na nhazi Mold

Njirimara ihe elektrọd graphite:

1.CNC nhazi ọsọ, elu machinability, mfe ewepụtụ

Igwe graphite nwere ngwa ngwa nhazi ngwa ngwa nke 3 ruo 5 ugboro nke electrode ọla kọpa, na imecha ọsọ dị ịrịba ama karịsịa, ike ya dịkwa elu. Maka ultra-high (50-90 mm), ultra-thin (0.2-0.5 mm) electrodes, ọ na-esiri ike ịhazi. Nrụrụ. Ọzọkwa, n'ọtụtụ ọnọdụ, ngwaahịa ahụ kwesịrị inwe mmetụta dị mma nke ọka, nke na-achọ ka a na-eme electrode n'ozuzu ya dị ka o kwere mee, na e nwere akụkụ dị iche iche zoro ezo mgbe a na-emepụta electrode dum, n'ihi njirimara trimming dị mfe nke graphite. . Nke a na-eme ka nsogbu ahụ dị mfe iji dozie ya, ma na-ebelata ọnụ ọgụgụ nke electrodes, ma electrode ọla kọpa enweghị ike.

2. Ngwa ngwa EDM na-akpụ, obere mgbasawanye ọkụ na obere ọnwụ

Ebe ọ bụ na graphite na-arụ ọrụ karịa ọla kọpa, ọ̀tụ̀tụ̀ ịgbapụ ya na-adị ngwa karịa ọla kọpa, bụ́ nke ji okpukpu atọ ruo 5 karịa ọla kọpa. Na ọ nwere ike iguzogide nnukwu ugbu a mgbe ọ na-agbapụta, ọ na-abakwa uru karị mgbe ọkụ eletrik na-arụ ọrụ siri ike. N'otu oge ahụ, ịdị arọ graphite bụ 1/5 ugboro nke ọla kọpa n'okpuru otu olu, nke na-ebelata ibu nke EDM nke ukwuu. N'ihi na uru nke na-eme nnukwu electrodes na n'ozuzu nwoke electrodes *. The sublimation okpomọkụ nke graphite bụ 4200 Celsius C, nke bụ 3 ka 4 ugboro nke ọla kọpa (na sublimation okpomọkụ nke ọla kọpa bụ 1100 Celsius C). N'ebe okpomọkụ dị elu, nrụrụ ahụ dị ntakịrị (1/3 ruo 1/5 nke ọla kọpa n'okpuru otu ọnọdụ eletrik) ma ghara ịdị nro. Enwere ike ibufe ike mgbapụta na workpiece nke ọma yana ọnụ ala dị ala. Ebe ọ bụ na a na-eme ka ike nke graphite dịkwuo elu na okpomọkụ dị elu, enwere ike ibelata nkwụsịtụ nke ọma (mfu graphite bụ 1/4 nke ọla kọpa), a na-ahụkwa na nhazi nhazi.

3. Ibu arọ na ọnụ ala dị ala

Na n'ichepụta ọnụ ahịa nke otu ihe na-akpụ akpụ, oge CNC machining, oge EDM, na ọnwụ electrode nke electrode na-akpata ihe ka ukwuu n'ime ọnụ ahịa zuru oke, nke a na-ekpebi site na ihe electrode n'onwe ya. E jiri ya tụnyere ọla kọpa, graphite nwere ngwa ngwa machining na ọsọ EDM nke 3 ruo 5 ugboro nke ọla kọpa. N'otu oge ahụ, àgwà ejiji dị oke ala na mmepụta nke electrode graphite zuru oke nwere ike ibelata ọnụ ọgụgụ nke electrodes ma belata ihe oriri na oge nhazi nke electrode. Ihe a niile nwere ike ibelata ego a na-akwụ iji mepụta ebu.
