Kutentha mankhwala-mtundu umodzi wa ndondomeko mu CNC Machining mbali

Kutentha mankhwalandi njira yomwe zida zachitsulo zimatenthedwa, zimatenthedwa ndikuzizizira mwanjira inayake, ndipo katundu wawo amayendetsedwa ndikusintha mawonekedwe a metallographic pamtunda kapena mkati mwazinthuzo.

Makhalidwe a ndondomeko

Kutentha kwazitsulo ndi imodzi mwazinthu zofunika kwambiri popanga makina.Poyerekeza ndi umisiri wina processing, kutentha mankhwala zambiri sasintha mawonekedwe ndi lonse mankhwala zikuchokera workpiece, koma amasintha microstructure mkati workpiece kapena kusintha mankhwala zikuchokera workpiece pamwamba., kupereka kapena kupititsa patsogolo ntchito ya workpiece.Amadziwika ndi kuwongolera bwino kwa mkati mwa workpiece, yomwe nthawi zambiri samawoneka ndi maso.

Pofuna kupanga zitsulo zopangira zitsulo kukhala ndi zofunikira zamakina, katundu wakuthupi ndi mankhwala, kuphatikizapo kusankha koyenera kwa zipangizo ndi njira zosiyanasiyana zopangira, njira yopangira kutentha nthawi zambiri imakhala yofunikira.Chitsulo ndiye chinthu chomwe chimagwiritsidwa ntchito kwambiri pamakampani opanga makina.The microstructure yachitsulo ndi yovuta ndipo imatha kuwongoleredwa ndi chithandizo cha kutentha.Choncho, chithandizo cha kutentha kwazitsulo ndizofunika kwambiri pazitsulo zotentha zachitsulo.Komanso, zotayidwa, mkuwa, magnesium, titaniyamu, etc. ndi aloyi awo akhoza kutentha mankhwala kusintha makina awo, thupi ndi mankhwala katundu kupeza ntchito zosiyanasiyana.

Njira ya chithandizo cha kutentha

Njira yochizira kutentha nthawi zambiri imakhala ndi njira zitatu zotenthetsera, kuteteza kutentha ndi kuziziritsa, ndipo nthawi zina pamakhala njira ziwiri zokha zowotchera ndi kuziziritsa.
Kutentha ndi imodzi mwa njira zofunika kwambiri zochizira kutentha.Pali njira zambiri zopangira kutentha kwachitsulo.Kugwiritsa ntchito makala ndi malasha koyambirira ngati magwero a kutentha, kenako kugwiritsa ntchito mafuta amadzimadzi ndi gasi.Kugwiritsa ntchito magetsi kumapangitsa kuti kutentha kukhale kosavuta kuwongolera komanso kopanda kuwononga chilengedwe.Magwero otenthawa atha kugwiritsidwa ntchito potenthetsera mwachindunji kapena kutenthetsa mwachindunji kudzera mumchere wosungunuka kapena zitsulo, komanso tinthu toyandama.
Chitsulo chikatenthedwa, chogwiritsira ntchito chimawonekera mumlengalenga, ndipo ma oxidation ndi decarburization nthawi zambiri zimachitika (ndiko kuti, mpweya wa carbon pamwamba pa gawo lachitsulo umachepetsedwa), zomwe zimakhala ndi zotsatira zoyipa kwambiri pamtunda wa mbali pambuyo kutentha mankhwala.Chifukwa chake, chitsulocho nthawi zambiri chimayenera kutenthedwa mumlengalenga wotetezedwa kapena mumlengalenga wotetezedwa, mumchere wosungunula komanso mu vacuum, komanso kutetezedwa ndi zokutira kapena zoyika.
Kutentha kwa kutentha ndi chimodzi mwazinthu zofunika kwambiri pakupanga chithandizo cha kutentha.Kusankhidwa ndi kulamulira kutentha kwa kutentha ndilo vuto lalikulu loonetsetsa kuti chithandizo cha kutentha chikhale chabwino.Kutentha kwa kutentha kumasiyanasiyana ndi zinthu zachitsulo zomwe ziyenera kukonzedwa komanso cholinga cha chithandizo cha kutentha, koma nthawi zambiri zimatenthedwa pamwamba pa kutentha kwa gawoli kuti mupeze mawonekedwe apamwamba kwambiri.Komanso, kusintha kumatenga nthawi ndithu, kotero pamene pamwamba pa zitsulo workpiece kufika chofunika Kutentha kutentha, ayenera anakhalabe pa kutentha uku kwa nthawi inayake kuti kutentha mkati ndi kunja kusasinthasintha ndi microstructure. kusintha kwathunthu.Nthawi imeneyi imatchedwa nthawi yogwira.Pamene kutentha kwamphamvu kwamphamvu ndi kutentha kwapamwamba kumagwiritsidwa ntchito, kuthamanga kwa kutentha kumakhala kofulumira kwambiri, ndipo nthawi zambiri kulibe nthawi yogwira, pamene nthawi yogwiritsira ntchito kutentha kwa mankhwala nthawi zambiri imakhala yaitali.
Kuziziritsa ndi gawo lofunikira kwambiri pakuchiritsa kutentha.Njira yozizirira imasiyanasiyana ndi njira zosiyanasiyana, makamaka kuwongolera kuzizira.Nthawi zambiri, kuziziritsa kwa kuziziritsa kumakhala pang'onopang'ono, kuziziritsa kwa normalizing kumakhala kofulumira, ndipo kuziziritsa kwa kuzimitsa kumathamanga kwambiri.Komabe, palinso zofunika zosiyanasiyana chifukwa cha mitundu yosiyanasiyana yachitsulo.Mwachitsanzo, chitsulo cholimba-cholimba chikhoza kuumitsidwa ndi kuzizira kofanana ndi kuzizira.
