Ukubumba okubandayoluhlobo lwetekhnoloji yokwenziwa kweplastiki echanekileyo, enezibonelelo ezingenakuthelekiswa nanto, ezinje ngeempawu ezilungileyo zoomatshini, imveliso ephezulu kunye nokusetyenziswa kwezinto eziphezulu, ezilungele ukuveliswa ngobuninzi, kwaye zinokusetyenziswa njengendlela yokuvelisa imveliso yokuphela, ukubanda okubandayo kwi-aerospace kunye nokuthutha. Ishishini lesixhobo somatshini wesixhobo kunye namanye amashishini anesicelo esibanzi. Okwangoku, uphuhliso olukhawulezayo lweshishini leemoto, ishishini lezithuthuthu kunye neshishini lesixhobo soomatshini libonelela ngamandla okuqhubela phambili kuphuhliso lwetekhnoloji yemveli yokubumba okubandayo.Inkqubo yokubumba ebandayoe China isenokungaqali kade, kodwa isantya uphuhliso has umsantsa omkhulu kunye namazwe aphuhlileyo, ukuza kuthi ga ngoku, imveliso yaseTshayina abandayo forging kwi imoto enobunzima obungaphantsi kwama-20 kg, elilingana nesiqingatha amazwe aphuhlileyo, unamandla amakhulu ophuhliso. , ukomeleza uphuhliso lweukukhwabanisa okubandayoitekhnoloji kunye nokusetyenziswa ngumsebenzi ongxamisekileyo kwilizwe lethu ngoku.
Ubume bezinto ezibandayo ezibandayo ziye zanzima ngakumbi, ukusuka kwinqanaba lokuqala le-shaft, izikrufu, izikrufu, amantongomane kunye nee-conduits, njl. Inkqubo eqhelekileyo ye-spline shaft yile: intonga ye-extrusion -- ukuphazamisa inxalenye yentloko ephakathi -- i-extrusion spline; Inkqubo ephambili yomkhono we-spline yile: umva wekomityi ye-extrusion - - ezantsi kwindandatho - - umkhono we-extrusion. Okwangoku, itekhnoloji ebandayo ye-extrusion yegiya ye-cylindrical nayo isetyenziswe ngempumelelo kwimveliso. Ukongeza kwisinyithi, i-alloy yobhedu, i-magnesium alloy kunye ne-aluminium alloy materials zisetyenziswa ngokubanzi kwi-extrusion ebandayo.

Inkqubo eqhubekayo yokusungula
Ukubumba okuchanekileyo okubandayo yinkqubo (kufuphi) yokwenza umnatha. Amalungu akhiwe ngale ndlela anamandla aphezulu, ukuchaneka okuphezulu kunye nomgangatho omhle womphezulu. Okwangoku, inani elipheleleyo le-forgings ebandayo esetyenziswa yimoto eqhelekileyo ngaphandle kwe-40 ~ 45kg, phakathi kwayo inani elipheleleyo leenxalenye zezinyo lingaphezulu kwe-10kg. Ubunzima obunye begiya elibandayo linokufikelela ngaphezulu kwe-1kg, kwaye ukuchaneka kweprofayili yezinyo kunokufikelela kumanqanaba asi-7.
Ukuveliswa kweteknoloji eqhubekayo kuye kwakhuthaza ukuphuhliswa kobuchwephesha be-extrusion ebandayo. Ukusukela ngeminyaka yoo-1980s, iingcaphephe ezithe ngqo zokwenziwa kwezinto ekhaya nakwamanye amazwe zaqala ukusebenzisa ithiyori ye-shunt forging ukuya ekubunjweni okubandayo kwe-spur kunye ne-helical gears. Umgaqo-siseko oyintloko we-shunt forging kukuseka i-shunt cavity okanye i-channel ye-material kwi-forming part ye-blank okanye yokufa. Kwinkqubo yokubumba, inxalenye yempahla igeleza kwi-shunt cavity okanye ishaneli ngelixa igcwalisa i-cavity. Ngokusetyenziswa kobuchwephesha bokubumba i-shunt, ukwenziwa kwesixhobo esichanekileyo esinexabiso elincinci kwaye akukho kusikwa kuye kwafikelela kwisikali seshishini. Kwiindawo ezikhutshiweyo ezinomlinganiselo wobude bobude be-5, njenge-piston pin, i-cold-extruded-time-time forming inokufezekiswa ngokwamkela i-axial residual block block ngokusebenzisa i-axial shunt ngokubanzi, kunye nokuzinza kwe-punch kulungile. Ukwenza i-flat spur gear, ukubunjwa okubandayo kwe-forging nako kunokuqondwa ngokusebenzisa iibhloko ze-radial residual material.
Block forging is a close die through one or two punches one-way-one or opposite extrusion of metal forming in one time , ukufumana kufutshane imilo ecocekileyo fayini forging ngaphandle flash edge. Ezinye iindawo ezichanekileyo zeemoto, ezifana neplanethi kunye nesiqingatha se-shaft gear, i-sleeve yeenkwenkwezi, i-cross bearing, njl., ukuba indlela yokusika yamkelwe, kungekhona kuphela izinga lokusetyenziswa kwezinto eziphantsi kakhulu (ngaphantsi kwama-40% kumyinge), kodwa kwakhona. iindleko zeeyure zabantu, iindleko eziphezulu zemveliso. Itekhnoloji yokubumba evaliweyo yamkelwa ukuvelisa ezi zixhobo ezicocekileyo zangaphandle, eziphelisa uninzi lwenkqubo yokusika kwaye zinciphise iindleko kakhulu.
Uphuhliso lwenkqubo yokubumba ebandayo kukuphuhlisa iimveliso eziphezulu zokunciphisa ixabiso lemveliso. Ngexesha elifanayo, lihlala lingena ngaphakathi okanye litshintshe iindawo zokusika, i-powder metallurgy, i-casting, i-hot forging, i-sheet metal forming, njl., kwaye inokudibaniswa nezi nkqubo ukwenza iinkqubo ezidibeneyo. Itekhnoloji eshushu yokubumba iplastiki yiteknoloji entsha yokwenza isinyithi echanekileyo edibanisa ukubunjwa okushushu kunye nokubumba okubandayo. Kuthatha inzuzo epheleleyo yokubumba okushushu kunye nokubumba okubandayo ngokulandelelanayo. Isinyithi esikwisimo esishushu sineplastiki elungileyo kunye noxinzelelo oluphantsi lokuhamba, ngoko ke inkqubo ephambili ye-deformation igqitywe ngokutshisa okutshisa. Ukuchaneka kokubumba okubandayo kuphezulu, ngoko ke imilinganiselo ebalulekileyo yamacandelo ekugqibeleni yenziwe yinkqubo ebandayo yokubumba. Itekhnoloji yokwenziwa kweplastiki eshushu yokubumba-ebandayo yavela ngeminyaka yoo-1980, kwaye ibisetyenziswa ngokubanzi ukusukela ngeminyaka yoo-1990. Iinxalenye ezenziwe ngobu buchwepheshe ziye zafumana iziphumo ezilungileyo zokuphucula ukuchaneka kunye nokunciphisa iindleko.
