Izingxenye Zemoto

Incazelo emfushane:

Lokhu kuphathelene nensimu ekhethekile ye-powder metallurgy, njengoba ukuminyana, i-porosity, izinto zokwakha kanye nezindlela zokwelashwa kokushisa kwama-powder metallurgy gear kuthinta ngqo ubulukhuni namandla. Ubuningi obukhulu bubhekisela kuzinto ze-alloy zobulukhuni obuphakeme, ama-pores amancane, ukuminyana okukhulu, okuhle Izindlela zokwelashwa ezishisayo zivame ukufaka ukuqedwa kwe-carburizing, i-carbonitriding, ukucisha imvamisa ephezulu, ukucima imvamisa ephansi, ukucima uwoyela, njll. Inqubo yokuqina nokufanelekayo yokuqeda ukucindezela kugcina ukuqina kokwelashwa kokushisa kuzinzile.


Imininingwane yomkhiqizo

Amathegi womkhiqizo

Ngenxa yokusebenza okuphezulu nezindleko eziphansi zezinto ezisetshenziswa nge-powder metallurgy, izingxenye zensimbi ye-powder zisetshenziswa kakhulu emotweni, kufaka phakathi izingxenye zokushaqeka, umhlahlandlela, i-piston kanye nesihlalo se-valve esiphansi ku-chassis yezimoto; Uhlelo lwe-brake lunenzwa ye-ABS, ibhuleki lokubhaka njalonjalo; Izingxenye zePompo ikakhulukazi iphampu kaphethiloli, iphampu kawoyela nepompo yokudlulisa ezingxenyeni ezisemqoka; Injini inomsele, indandatho yesihlalo, induku yokuxhuma, isihlalo esithwele, izingxenye ezisemqoka zohlelo lokushintsha isikhathi se-valve (VVT) nokukhipha ukwesekwa kwepayipi, njll Ukudluliswa kunehabhu lokuvumelanisa nohlaka lwamagesi eplanethi nezinye izingxenye.

Ukuthuthukiswa kwezingxenye ze-powder metallurgy auto

Ngokuthuthuka okusheshayo komkhakha wezimoto waseChina, imakethe yezingxenye zezimoto ibuye yagcina ukuthambekela okusheshayo.Ngonyaka ka-2015, ukukhishwa okuzenzakalelayo kweChina kufinyelele kumayunithi ayizigidi ezingama-24.5033, kukleliswa kuqala emhlabeni.Imboni yokukhiqiza izingxenye zezimoto zaseChina izuze imali engenayo yokuthengisa engu-3.23 trillion yuan, kukhuphuke cishe amaphesenti ayi-10 kusuka ngonyaka owedlule Ngakolunye uhlangothi, ngemuva kokungena kweChina enhlanganweni yezokuhweba emhlabeni, akugcini nje ngokwakha isethi ephelele yezimboni zezimoto zakwamanye amazwe ezifana nababungazi, naku-oda lasekhaya elikhulu lezingxenye zensimbi yensimbi, imikhiqizo ngayinye, kanye nezinkampani ezingamazwe angaphandle ezitshala imali ezweni lethu, ukwakha isethi ephelele yemikhiqizo yensimbi eyimpuphu ehlinzeka okwenziwa endaweni okwedingeka kakhulu kuyo, isidingo sokunweba ekuthuthukiseni amabhizinisi we-powder metallurgy eChina silethe ithuba elingandile.

Kusukela ekubukeni kokuthengisa okukhiphayo inani lezingxenye ze-powder metallurgy auto, inani lokukhishwa kokuthengisa lenyuke lisuka ku-876.21 million yuan ngo-2006 laya ku-367.826 million yuan ngo-2015, ngenani lokukhula lonyaka eli-17.28%, futhi ligcina ukuthambekela kokukhula okusheshayo okuqhubekayo , kanye ne-powder metallurgy auto izingxenye zemfuno yezimakethe zigcine ukuthambekela kokukhula okusheshayo.

Ukuqina kokuqina kwemikhiqizo yensimbi ejwayelekile yensimbi ngesikhathi sokwelashwa kokushisa

Ubuningi be-powder evamile ene-atomised (kufaka phakathi i-carbon steel ne-copper-carbon alloy steel) ingaphezulu kuka-6.9, futhi ukuqina kobunzima kungalawulwa nge-HRC30.

Ngokuvamile, ubukhulu be-powder esetshenzisiwe ngaphambili (i-AB powder) yeqa u-6.95, nobulukhuni bokucima bungalawulwa nge-HRC35.

Ama-powders asetshenzisiwe aphezulu anesisindo esikhulu kuno-6.95 nokucisha ukuqina okulawulwa ku-HRC40.

Imikhiqizo yensimbi ye-Powder eyenziwe ngezinto ezingenhla inokuqina okuzinzile nezinto ezibonakalayo, futhi ubulukhuni ngemuva kokwelashwa kokushisa buhlangabezana nezidingo ezihambisanayo, ngakho-ke amandla abo okuqina namandla acindezelayo azofinyelela phezulu kakhulu.

Ingabe ubunzima bokwelashwa kokushisa kwe-powder metallurgy bungafinyelela ku-45 steel?

Kodwa-ke, ngenxa yokuthi ubukhulu bemikhiqizo ye-PM abuphakeme njengobukaNombolo 45 wensimbi, ukuminyana okuphezulu kakhulu kwezingxenye zokucindezela u-PM kuvame ukuba ngu-7.2 g / cm, kanti ukuminyana kwensimbi engu-45 kungu-7.9 g / cm. we-powder metallurgy noma we-high frequency heat treatment owedlula i-HRC45 kuzokwenza ukuthi imikhiqizo ye-metallurgy brittle ibe namandla ngenxa yokucima okuphezulu, okuholele emandleni emikhiqizo ye-powder metallurgy.

Okulandelayo, sizoqhathanisa igiya elenza i-P / M negiya lokulungisa ngomshini.

1.Izinga eliphakeme lokusetshenziswa kwempahla, lifinyelela ngaphezu kuka-95%

2. Akukho noma ukusika okuncane kuphela okudingekayo

3.Ukuhambisana okuhle kwezingxenye, ukuzinza okuhle nokunemba okuphezulu.

4. Ukuqhathaniswa kwamandla: abakhiqizi be-powder metallurgy abaqeqeshiwe benze ubuhle be-metallurgy mold design, futhi amandla okuqina namandla okucindezela amagiya akhiqizwayo aseduze kwalawo we-gear hobbing.Isibonelo, igiya eliqhutshwa u-gearbox wemoto onokudluliswa okuphezulu umfutho ubuye ube yimpuphu yokusansimbi.Ibonakalayo, i-powder metallurgy gear iyasebenza futhi ibanzi.

5. Powder ngokucindezela udini usebenzisa isikhunta udini, kungaba ukukhiqiza ezinye ahlabayo hobbing ubuchwepheshe abakwazi ukukhiqiza bobunjwa eziyinkimbinkimbi.

6. Ngoba ilungele ukukhiqizwa ngobuningi, ukusebenza kahle kokukhiqiza kuphezulu futhi izindleko ziphansi kunokusika.

7. Kufanelekile ukukhiqizwa ngobuningi, ngakho-ke intengo incintisana ngokuphelele.
