Steel mmanya quenching na tempering mmepụta akara
Steel mmanya quenching na tempering mmepụta akara
A. Uru nke ígwè mmanya quenching na tempering mmepụta akara
1. Na ígwè mmanya quenching na tempering mmepụta akara nwere ike dị mkpụmkpụ ihe nchara mmanya na -akwụsị ma na -ewepụta usoro nrụpụta ma melite ọnọdụ ọrụ.
2. Ogwe nchara na -akwụsị ma na -ewepụta nrụpụta ọkụ nwere ike melite ọkwa nhazi nke mmanya nchara na imepụta mmepụta ma melite ogo ngwaahịa.
3. Ngwa nrụnye ọkụ nke eriri nchara na imeputa ahịrị nrụpụta na -echekwa ihe karịa ọkụ na -ere ọkụ, yana n’otu oge ahụ na -eme ka ndụ ọrụ nke ogwe nchara dị mma ma emesịa.
4. Ogwe nchara na -agbanyụ ma na -ewe iwe ọkụ anaghị emepụta anwụrụ ọkụ na anwụrụ ọkụ n’ihi itinye ọkụ, nke na -asachapụ ebe ọrụ ogbako ahụ.
5. Oge nnabata induction nke mmanya nchara na imeputa ahịrị mmepụta dị mkpụmkpụ yana arụmọrụ dị elu.
B. Isi nke ígwè mmanya na -akwụsị na tempering mmepụta akara
1. A na -ejikwa eriri nrụpụta ihe nchara na -agbanyụ mmanya na -ewe iwe ma na -ewe iwe ọkụ, a na -emepekwa mmezi ahụ n’ụzọ zuru oke iji nweta ike dị elu.
2. Na -ebugharị okpokoro okpokoro: axis nke tebụl rola na axis nke workpiece na -etolite n’akuku 18 ~ 21 Celsius, ebe a na -arụ ọrụ na -aga n’ihu na ọsọ mgbe ọ bụla na -ebugharị, ka ikpo ọkụ wee bụrụ otu. Tebụl ala dị n’etiti ọkụ ahụ bụ nke igwe anaghị agba nchara 304 na mmiri jụrụ oyi. Akụkụ ndị ọzọ nke tebụl rola bụ nke nchara 45 nchara na elu kpọrọ nkụ.
3. Nchịkọta okirikiri nke igwe na -agbanyụ na ngwa ịkpa ọkụ: igwe nri, otu ihe mmetụta na ndị na -ewepụta ihe na -ejikwa ihe ntụgharị ugboro ugboro dị iche, nke bara uru maka ọsọ ọsọ nke ụlọ mmanya n’oge usoro ịga n’ihu.
4. Usoro emechiri emechi okpomoku: Ọ na-anabata temometa infrared American Leitai jikọtara ya na German Siemens S7 iji mepụta usoro njikwa mechiri emechi, nke nwere ike ijikwa oke okpomọkụ na ikpo ọkụ karịa.
5. Kọmpụta ụlọ ọrụ na -ejikwa igwe na -ebelata ihe na -ewe iwe na -ewe iwe, nke na -egosipụta ọnọdụ nke paramita ndị na -arụ ọrụ n’oge ozugbo, yana ọrụ dị ka ebe nchekwa ọrụ, nchekwa, ibipụta, ngosi mmejọ, na ịgbalite mgbaàmà mberede. .
6. The workpiece mgbe emenyụ ọkụ na tempering na ígwè mkpanaka na tube mmepụta akara nwere adịghị gbawara agbawa na ọ dịghị deformation, na ruru eru ọnụego nke okokụre ngwaahịa dị elu dị ka 99%.
7. Parallel na usoro resonance teknụzụ njikwa nwere ikike maka ogwe nchara nchara na iwepụta ọkụ eletrik, ihuenyo mmetụ zuru oke dijitalụ arụ ọrụ induction kpocha ọkụ na iwe ọkụ akụrụngwa ọgwụgwọ ọkụ, bụ ngwa teknụzụ teknụzụ kpo oku mba ụwa.
C. Case ọmụmụ nke ígwè mmanya na -akwụsị na tempering mmepụta akara:
1. A na-eji ahịrị nchara na-eme ka ọ dị ọkụ ma na-ewe iwe ọkụ maka mkpa ọkụ ọkụ nke mkpanaka hydraulic na mkpanaka ndị na-amị amị.
2. Akụkụ nke ogwe nchara emenyụla ma rụọ ọrụ arụ ọrụ
1) Ngwa ihe: 45# nchara, 40Cr, 42CrMo
2) Ngwaahịa (mm): dayameta: 60≤D≤150 (mkpanaka igwe siri ike) Ogologo: 2200mm ~ 6000mm;
3) A na-eme ka ogwe nchara na-eme ka ọ dị ọkụ site na ugboro ugboro wee jụọ oyi maka ịgwọ ọgwụgwọ, a na-arụkwa tempering na ntanetị.
Ịgbanyụ okpomọkụ okpomọkụ: 950 ± 10 ℃; Tempering kpo oku okpomọkụ: 650 ± 10 ℃;
4) Input voltaji: 380V ± 10%
5) Nrụpụta chọrọ: 2T/H (dabere na ogwe nchara 100mm)
D. Nka na ụzụ chọrọ maka ígwè mmanya na -akwụsị na tempering mmepụta akara:
1) Nkịtị siri ike nke ogwe osisi niile bụ ogo 22-27 HRC, ike kacha nta enweghị ike ịbụ ihe na-erughị ogo 22, na ekweghị ekwe kwesịrị ekwesị bụ ogo 24-26;
2) Ike nke otu ogwe osisi ahụ ga-abụrịrị otu, na ike nke otu ogbe ahụ ga-abụkwa otu, na ịdị n’otu nke oghere ga-adị n’etiti ogo 2-4.
3) nzukọ a ga -abụrịrị otu, na ihe nrụzi ga -emerịrị ihe ndị a chọrọ:
a. Ike ịmị mkpụrụ karịrị 50kgf/mm²
b. Ike ọdụdọ karịrị 70kgf/mm²
c. Ogologo ya karịrị 17%
4) Ebe kachasị dị n’etiti etiti okirikiri agaghị adị ala karịa HRC18, ebe kachasị ala nke 1/2R agaghị adị ala karịa ogo HRC20, ebe kacha ala nke 1/4R agaghị adị ala karịa ogo HRC22.
E. Nkọwa nke usoro eruba nke ígwè mmanya quenching na tempering mmepụta akara
Nke mbụ, jiri aka tinye mkpara nchara dị mkpa ka ewe iwe ọkụ n’otu ahịrị na otu akwa na akwa nchekwa nri, mgbe ahụ igwe na -ebugo ihe na -eji nwayọ eziga ya na nri nri, wee tinye ihe ahụ n’ime. na -enye nri ala ala site na cylinder ikuku. Igwe na -amị amị na -ebufe ihe mgbochi mmanya n’ihu wee ziga ya ihe na -emenyụ ọkụ inductor. Mgbe ahụ, a na -eme ka akụkụ ọrụ ahụ dị ọkụ site na imenyụ akụkụ kpo oku, a na -ekewakwa imi ọkụ ọkụ n’ime ọkụ kpochapụ kpo oku na ịchekwa ikpo ọkụ. N’akụkụ ọkụ na -agbanyụ ọkụ, a na -eji ọkụ ọkụ ọkụ dị n’etiti 600Kw iji kpoo ihe ọrụ ahụ, mgbe ahụ, a na -eji usoro ike abụọ 200Kw maka ike nchekwa na ikpo ọkụ.
Mgbe emechara kpo oku ahụ, igwe ihe eji arụ ọrụ na -ebugharị ya ka ọ gafee n’ofe mgbanaka ịgba mmiri. Mgbe emenyụchara ọkụ, ọ na -abanye na inductor kpo oku maka iwe ọkụ. A na -ekewakwa ikpo ọkụ ọkụ ọkụ ụzọ abụọ: ikpo ọkụ ọkụ na ichebe ọkụ. Akụkụ kpo oku na -anabata ọkụ eletrik dị n’etiti 300Kw, akụkụ nchekwa ọkụ na -ewerekwa usoro abụọ nke 100KW.
Ogwe nchara na nchara mmanya na-akwụsị ma na-ewepụta usoro nrụpụta na-ahọrọ usoro dị elu na ọnụ ahịa dị ka usoro chọrọ nke onye ahịa chọrọ. Usoro mmepụta zuru oke gụnyere akụrụngwa kpo oku ugboro ugboro, ngwaọrụ na -ebugharị igwe, ngwaọrụ nha infrared, sistemụ jụrụ mmiri mechiri emechi, na igbe njikwa etiti wdg.
