1. Inkcazo yokubumba okubandayo
Ukubumba okubandayo, okwakwaziwa ngokuba kukwenziwa komthamo obandayo, yinkqubo yokuvelisa kunye nendlela yokulungisa.Ngokusisiseko iyafana nenkqubo yokunyathela, inkqubo yokubumba ebandayo iqulunqwe ngezinto, iimolds kunye nezixhobo.Kodwa imathiriyeli ekusetyenzweni kwesitampu ubukhulu becala yipleyiti, kwaye imathiriyeli ekusetyenzweni okubandayo kokubunjwa ngocingo lwediski.I-Japan (i-JIS) ebizwa ngokuba yi-cold forging (i-cold forging), i-China (i-GB) ebizwa ngokuba yi-cold heading, ngaphandle kwe-screw factory efana nokubiza intloko.
2. Iingcamango ezisisiseko zokubumba okubandayo
Cold forging ibhekisela kwiqondo lobushushu metal recrystallization ngaphantsi ezahlukeneyo umthamo ukwenza.Ngokutsho kwethiyori ye-metalology, ubushushu bokuhlaziya izinto ezahlukeneyo zetsimbi buhlukile.T = (0.3 ~ 0.5) T nyibilika.Ubuncinci beqondo lobushushu bekristali besinyithi kunye nesinyithi.Kwanakwiqondo lobushushu begumbi okanye ubushushu obuqhelekileyo, inkqubo yokuyila ilothe nenkcenkce ayibizwa ngokuba yinto ebandayo yokubumba, kodwa ukubumba okushushu.Kodwa isinyithi, ubhedu, i-aluminium eyenza inkqubo kwiqondo lobushushu begumbi inokubizwa ngokuba yi-cold forging.
Kwi-metallics, ukubunjwa kwezinto ezifudunyezwe ngaphezulu kobushushu bokubuyisela kwakhona (malunga ne-700 ℃ yentsimbi) kubizwa ngokuba yi-hot forging.
Kwizinto zentsimbi, iqondo lobushushu elingaphantsi kwakhona kwaye liphezulu kunobushushu obuqhelekileyo bokubunjwa bubizwa ngokuba yi-forming efudumeleyo.
Izinto ezilungileyo zesihloko esibandayo (extrusion)
Kwi-fastener forming, i-teknoloji ebandayo (i-extrusion) iteknoloji yokucubungula iteknoloji.Isihloko esibandayo (i-extrusion) siyinxalenye yodidi loxinzelelo lwesinyithi.Kwimveliso, kwiqondo lokushisa eliqhelekileyo, isinyithi sisetyenziselwa amandla angaphandle, ukwenzela ukuba isinyithi ekubunjweni kwangaphambili, le ndlela ibizwa ngokuba yi-cold heading.
Ukuqulunqwa kwaso nasiphi na isibophelelo ayisiyiyo kuphela indlela yokuguqulwa kwentloko ebandayo, inokuqondwa kwinkqubo yesihloko esibandayo, ukongeza kwi-deformation ephazamisayo, kodwa ihamba kunye ne-extrusion yangaphambili nasemva, i-composite extrusion, i-punching cut, i-rolling kunye nezinye. iindlela deformation.Ngoko ke, igama lesihloko esibandayo kwimveliso ligama lesintu kuphela, kwaye kufuneka libizwe ngokubanda kwesihloko (ukucudisa) ngokuchanekileyo ngakumbi.
Isihloko esibandayo (i-extrusion) ineenzuzo ezininzi, ifanelekile kwimveliso yobuninzi be-fasteners.Iinzuzo zayo eziphambili ikakhulu ziquka le miba ilandelayo:
Izinga eliphezulu lokusetyenziswa kwentsimbi, isihloko esibandayo (ukucudisa) yindlela yokuncinci, akukho kusika, njengentonga yokucubungula, i-cylinder head hex socket screws, i-hex head bolt machining method, izinga lokusetyenziswa kwentsimbi kwi-25% ~ 35%, kunye kuphela ngesihloko esibandayo (ukucudisa) indlela, kwaye izinga lokusetyenziswa kwayo linokuba phezulu ukuya kuma-85% ~ 95%, yintloko nje, umsila kunye nentloko ye-hex enqunywe enye yenkqubo yokusetyenziswa.
Imveliso ephezulu: xa kuthelekiswa nokusikwa ngokubanzi, isihloko esibandayo (i-extrusion) yenza ukusebenza ngokufanelekileyo kumaxesha amaninzi aphezulu kunoko.
Iimpawu ezilungileyo zomatshini: ukuqhutyelwa kwesihloko esibandayo (i-extrusion) yamacandelo, kuba i-fiber yensimbi ayinqunywanga, ngoko ke amandla angcono kakhulu kunokusika.
Ifanelekile kwimveliso ezenzekelayo: i-fasteners (kwaye ibandakanya ezinye iindawo ezinokwakheka okukhethekileyo) ezifanelekileyo kwisihloko esibandayo (i-extrusion) imveliso ngokusisiseko i-symmetrical parts, ifanelekile kwi-high-speed automatic automatic heading machine production, ikwayeyona ndlela iphambili yemveliso yobuninzi.
Ngelizwi, indlela ebandayo yesihloko (i-extruding) luhlobo lwendlela yokucubungula kunye nenzuzo ephezulu yezoqoqosho, esetyenziswa ngokubanzi kwishishini le-fastener.Kwakhona yindlela yokuqhubela phambili esetyenziswa ngokubanzi ekhaya nakwamanye amazwe ngophuhliso olukhulu.
