Kwenguva yakareba, mainjiniya uye vangangove vatengi vanga vachienzanisa simbi yehupfu nemaitiro ekukwikwidza.Kana zviri zvehupfu simbi zvikamu uye zvikamu zvakaumbwa, senge chero imwe kuenzanisa yekugadzira nzira, inobatsira kunzwisisa zvakanakira uye zvinogona kukanganisa zvega rega maitiro.Powder metallurgy (PM) inopa akawanda mabhenefiti aunofanirwa kufunga-mamwe ari pachena, mamwe haana akawanda.Zvechokwadi, mune zvimwe zviitiko, kuumba kunogonawo kuva sarudzo yakanaka.Ngatitarisei mashandisirwo akakodzera uye mashandisirwo ehupfu simbi uye zvikamu zvefogi:

1. Upfu simbi uye forgings

Kubva zvave zvakakurumbira, simbi yehupfu yakave mhinduro iri pachena yekugadzira zvikamu zvidiki mumamiriro mazhinji.Panguva ino, unogona kukakavara kuti akawanda akakandwa anogona kutsiviwa nePM akatsiviwa.Saka, ndeupi muganhu unotevera wekushandisa zvizere simbi dzehupfu?Zvakadini nezvidimbu zvefodya?Mhinduro yacho yakanangana nechikumbiro chako.Izvo hukama hwezvinhu zvakasiyana-siyana zvekugadzira zvinhu (forgings chikamu chazvo), uye zvino ratidza nzvimbo yehupfu simbi yakakodzera tsanangudzo.Izvi zvakateya hwaro hwePM iripo, uye zvakanyanya kukosha, iyo inogoneka PM.Tarisa papi 80% yeindasitiri yehupfu yesimbi inotsamira pane simbi yakakandwa, phosphor bronze, nezvimwewo. Zvisinei, zvikamu zvehupfu zvesimbi zvino zviri nyore kukunda zvigadzirwa zvesimbi.Muchidimbu, kana ukaronga kushandisa yakajairwa simbi-mhangura-kabhoni kugadzira zvikamu, saka simbi yehupfu inogona kunge isiri yako.Nekudaro, kana iwe ukatsvaga zvimwe zvepamberi zvinhu uye maitirwo, PM inogona kupa kuita kwaunoda nemutengo wakaderera pane wekugadzira.

2. Ngatitarisei zvimwe zvakanakira nekuipira kwesimbi yeupfu uye zvikamu zvakafodhiwa:

A. Metal upfu metallurgy zvikamu

1. Zvakanakira zvehupfu metallurgy:

Zvikamu zvinogona kugadzirwa nezvinhu zvinogona kupa basa repamusoro-tembiricha uye kusimba kwepamusoro, uye mutengo unoderedzwa.Funga nezvesimbi isina tsvina, iyo iri pasi pekupisa kwakanyanya mumagetsi emhepo, nezvimwe.

Inogona kuchengetedza kubereka kwakanyanya kwezvikamu, kunyange zvikamu zvakaoma.

Nekuda kweiyo mambure shapeability yehupfu metallurgy, mazhinji acho haadi machining.Kuderera kwechipiri kugadzirisa kunoreva kuderera kwemari yebasa.

Kushandiswa kwesimbi poda uye sintering inogona kuwana yakakwirira yekutonga.Izvi zvinobvumira kukwenenzverwa kwe electromagnetic zvivakwa, density, damping, kuoma uye kuoma.

High tembiricha sintering inonatsiridza zvakanyanya kusimba kwesimba, kukotamisa kuneta simba uye kukanganisa simba.

2. Kuipa kweupfu metallurgy:

PM zvikamu zvinowanzove nehukuru miganhu, izvo zvinogona kuita kuti mamwe madhizaini asaite kugadzira.Muchina wokutsikirira mukurusa muindasitiri iyi ungangoita matani 1,500.Izvi zvinomisa iyo chaiyo chikamu saizi kune yakati sandara nzvimbo inosvika 40-50 square inches.Zvine chokwadi, avhareji saizi yekutsikisa iri mukati memazana mashanu matani, saka ndapota ita hurongwa hwekuvandudza chikamu chako.

Zvikamu zvine zvimiro zvakaoma zvinogona zvakare kunetsa kugadzira.Nekudaro, vagadziri vane hunyanzvi hwesimbi zvikamu vanogona kukunda dambudziko iri uye kunyange kukubatsira kugadzira.

Zvikamu kazhinji hazvina kusimba kana kutambanuka sesimbi yakakandwa kana zvikamu zvakafogirwa.
