I. Ihe mkpuchi laser: "ịwa ahụ nke ọma" nke nrụpụtagharị igwe kol

Ihe mkpuchi laser abụghị ihe dị mfe "ihe nkiri" elu, kama ọ bụ teknụzụ kachasị ọhụrụ nke na-emepụta ọdọ mmiri na-agbaze obere n'elu ihe mejupụtara ya na nnukwu ọkụ laser ma na-efesa ntụ ntụ alloy pụrụ iche n'otu oge iji nweta njikọ metallurgical n'etiti oyi akwa mkpuchi na ntọala. Isi uru ya dị na:

Ndozi ebumnuche kpọmkwem: Enwere ike ịtọpụ oghere laser ahụ kpọmkwem ka ọ yie oghere na olulu nchara, na-ezere mmebi nke ihe dị mma, karịsịa maka ịrụzi ntụpọ mpaghara dịka ọkọ na ogidi hydraulic na ọkọ na mgbidi dị n'ime silinda.

Njikọ siri ike na nke siri ike nke metallurgical: Okpokoro mkpuchi na matrix na-emepụta ngwakọta mgbasa ozi atọm, ike njikọ ahụ ruru 400MPa, na-ewepụ kpamkpam ihe egwu nke ịkpụcha chromium plating.

Arụmọrụ ahaziri: Site n'ịhọrọ ihe mejupụtara cobalt nke na-eguzogide iyi (dịka Stellite 6), ihe mejupụtara nickel nke na-eguzogide nchara ma ọ bụ tungsten carbide nke e ji ígwè rụọ, enwere ike ime ka ikike ịlanarị nke ihe ndị dị n'ọnọdụ ọrụ siri ike dị ka mmetụta coal gangue na mmebi mmiri acid dị mma.

II. Ngwa bara uru: Site na "ịkpụcha ọnụ" ruo "ịrụ ọrụ karịrị akarị"

1. Nkwado hydraulic "mgbanwe ndọtị ndụ"

Mgbe e wepụrụ oyi akwa mkpuchi chromium n'elu kọlụm hydraulic, kọlụm ahụ ga-adị mfe ịta nchara ma daa n'okpuru nrụgide dị elu. Teknụzụ mkpuchi laser nwere ike:

Mgbe ewepụsịrị ihe mkpuchi ochie ahụ, A na-etinye oyi akwa alloy nke dabere na cobalt nke dị 0.8-1.5mm ozugbo n'elu ihe mkpuchi ahụ;

A na-eme ka ike sie ike ruo HRC 55-60 (oyi akwa mkpuchi chromium mbụ bụ naanị HRC 40-45), a na-emekwa ka iguzogide iyi ahụ dịkwuo elu karịa ugboro atọ;

A na-eme ka iguzogide nchara dịkwuo mma nke ukwuu. Ndụ ọrụ nke kọlụm ndozi nke ebe a na-egwuputa ihe n'ime mmiri ebe a na-egwuputa ihe n'ime acid ruru ọnwa iri na asatọ, nke karịrị nke mbụ ọhụrụ (ọnwa isii ruo asatọ).

2. A "megharịrị" oghere etiti nke igwe ịkpụcha ihe

Nha kwa afọ nke ihe e ji eme ihe n'ala ala nke ihe e ji eme ihe n'etiti ya ruru 15mm, ebe ihe e ji eme ihe n'oge ochie na-efu ihe karịrị yuan 20,000 kwa nkeji. Ngwọta mkpuchi laser na-etinye ihe mejupụtara ígwè nke tungsten carbide nke e ji ihe ndị na-emebi emebi mee n'ebe ndị a na-eyi ihe n'ime mgbidi ihe e ji eme ihe. Site n'inweta ike elu karịrị HRC 62, ihe ọhụrụ a na-eme ka iguzogide iyi dịkwuo elu ugboro 5-8. Ngwa ubi n'ebe a na-egwupụta ihe na-egosi na ihe e ji eme ihe n'etiti ihe e ji eme ihe na-agbatị ndụ ọrụ site na ọnwa 6 ruo ọnwa 24, ebe ọnụ ahịa mmezi kwa tọn nke coal na-ebelata site na 40%.

3. "Nrụgharị" nke mgbidi dị n'ime nke silinda hydraulic

Iji dozie nsogbu mkpuchi nke silinda kpatara: Sistemụ a na-eji ntụ ntụ coaxial yana ihe e ji laser mee maka oghere dị n'ime, na-eme ka njikọta ahụ dị mma n'ebe ndị a kpachiri ekechi. Nrụgide elu mgbe a rụchara ọrụ (Ra ≤ 0.8μm) karịrị ụkpụrụ nhazi akụkụ ọhụrụ. Nnwale ubi na ụlọ ọrụ igwe kol na-egosi na silinda ndị a rụziri arụrụ na-enweta nrubeisi arụmọrụ mkpuchi 100% ebe ọ na-efu naanị 30% nke mmepụta silinda ọhụrụ.

III. Mgbanwe Atọ: Akụnụba, Ịrụ Ọrụ nke Ọma na Mgbanwe Akwụkwọ Ndụ

IV. Site na nrụzi ruo na nkwalite: ọdịnihu nke nrụpụta nke injin kol nwere ọgụgụ isi

Site na njikọta nke teknụzụ nwere ọgụgụ isi, mkpuchi laser na-eru elu ọhụrụ na ngwa igwe kol: 1) Ebe ọrụ robot akpaaka na-eme ka mmezi nke ihe dị ka kọlụm na silinda nke a haziri nke ọma na-eme ka arụmọrụ dịkwuo mma site na 50%; 2) Nlekọta mmezi amụma dijitalụ ejima na-enyocha ihe mmetụta iji rụọ ọrụ nke ọma tupu ọdịda emee; 3) Ihe ndị na-arụ ọrụ gradient na-emepụta akwa mkpuchi mejupụtara nwere elu siri ike maka iguzogide iyi na akwa dị n'ime siri ike na-eguzogide mgbawa, na-edozi ọnọdụ ọrụ ejikọtara na mmetọ.
