Cold forgingimhando yehunyanzvi hwekugadzira mapurasitiki ekugadzira tekinoroji, ine machining asingaenzaniswi mabhenefiti, akadai seakanaka emuchina zvivakwa, kugadzirwa kwepamusoro uye kushandiswa kwezvinhu zvakanyanya, kunyanya kwakakodzera kugadzirwa kwakawanda, uye inogona kushandiswa seyekupedzisira chigadzirwa nzira yekugadzira, kutonhora kwekugadzira mumhepo uye chekufambisa. Turusi muchina chishandiso indasitiri uye mamwe maindasitiri ane akawanda application. Parizvino, kukurumidza kusimudzira indasitiri yemotokari, indasitiri yemidhudhudhu uye indasitiri yezvishandiso zvemuchina inopa simba rekufambisa rekuvandudza tekinoroji yechinyakare yekutonhora kuforoma.Cold forging processmuChina inogona kusatanga kunonoka, asi kukurumidza kwekusimudzira kune gap guru nenyika dzakabudirira, kusvika ikozvino, kugadzirwa kweChina kwechando chekugadzira pamotokari inorema isingasviki 20 kg, yakaenzana nehafu yenyika dzakabudirira, ine mukana mukuru wekusimudzira. , kusimbisa kukura kwekutonhora kwekugadziratekinoroji uye kushandisa ibasa rekukurumidzira munyika yedu parizvino.
Chimiro chechando chekugadzira chave chichiwedzera kuoma, kubva padanho rekutanga shaft, screws, screws, nuts uye conduits, nezvimwewo, kusvika kune yakaoma forgings. Iyo yakajairika maitiro e spline shaft ndeye: extrusion tsvimbo -- inogumbura iyo yepakati musoro chikamu -- extrusion spline; Iyo huru maitiro e spline sleeve ndeye: kumashure extrusion kapu - - pasi mumhete - - extrusion sleeve. Parizvino, iyo inotonhora extrusion tekinoroji yecylindrical giya yakashandiswawo zvakabudirira mukugadzira. Pamusoro pematare ane ferrous, copper alloy, magnesium alloy uye aluminium alloy zvinhu zvinowedzera uye zvakanyanya kushandiswa mukutonhora extrusion.

Continuous process innovation
Cold precision forging i (padyo) yekugadzira mambure. Zvikamu zvakaumbwa neiyi nzira zvine simba rakawanda, kurongeka kwepamusoro uye kunaka kwepamusoro. Parizvino, huwandu hwakakwana hwehuputi hunotonhora hunoshandiswa nemotokari yakajairika kunze kwenyika ndeye 40 ~ 45kg, pakati peiyo huwandu hwezvikamu zvezino zvinopfuura 10kg. Huremu humwe chete hwemagiya anotonhora anogona kusvika kupfuura 1kg, uye iko kurongeka kwezino rezino kunogona kusvika 7 mazinga.
Kuenderera mberi kwehunyanzvi hwekuvandudza tekinoroji kwakasimudzira kuvandudzwa kweinotonhora extrusion tekinoroji. Kubva kuma1980, nyanzvi dzekuumba nyanzvi kumba nekune dzimwe nyika dzakatanga kushandisa dzidziso yeshunt forging kune inotonhora yekugadzira spur uye helical gears. Nheyo huru yeshunt forging ndeyekumisikidza shunt mhango kana chiteshi chezvinyorwa muchikamu chekugadzira chechinhu chisina chinhu kana kufa. Mukugadzira, chikamu chechinhu chinoyerera chichienda kune shunt cavity kana chiteshi ichizadza mhango. Nekushandiswa kweshunt forging tekinoroji, machining emhando yepamusoro giya ine zvishoma uye pasina kucheka kwakurumidza kusvika pachiyero cheindasitiri. Kune zvikamu zvakawedzeredzwa zvine hurefu-dhayamita reshiyo ye5, senge piston pin, inotonhora-yakasimudzwa imwe-nguva kuumba inogona kuwanikwa kuburikidza nekutora axial residual material block kuburikidza neaxial shunt zvakanyanya, uye punch kugadzikana kwakanaka. Kune flat spur giya rekugadzira, iyo inotonhora extrusion kuumbwa kwe forgings inogona zvakare kuitika nekushandisa radial yasara mabhuroko.
Block forging is a close die through one or two punches one-way or opposite extrusion of metal forming in one time, to get near clean shapeging forging without flash edge. Zvimwe zvikamu zvechokwadi zvemotokari, senge mapuraneti nehafu shaft giya, nyeredzi sleeve, kutakura muchinjiko, nezvimwewo, kana nzira yekucheka ikagamuchirwa, kwete chete mwero wekushandisa zvinhu wakadzikira (pasi pe40% paavhareji), asiwo. mutengo wemaawa emunhu, mutengo wekugadzira wakakwira. Iyo yakavharwa yekugadzira tekinoroji inogamuchirwa kugadzira aya akachena forgings kunze kwenyika, ayo anobvisa mazhinji ekucheka maitiro uye anoderedza mutengo zvakanyanya.
Iko kuvandudza kwekutonhora kwekugadzira maitiro kunonyanya kugadzira yakakwira-yakawedzerwa zvigadzirwa kudzikisa mutengo wekugadzira. Panguva imwecheteyo, inogara ichipinda kana kutsiva minda yekucheka, poda metallurgy, kukanda, kupisa kupisa, simbi yekugadzira, nezvimwewo, uye inogona zvakare kusanganiswa nemaitiro aya kuti iite composite maitiro. Kupisa kuumba-kutonhora kuumbiridza komputa yepurasitiki yekugadzira tekinoroji ndiyo nyowani chaiyo simbi yekugadzira tekinoroji iyo inosanganisa kupisa kunopisa uye kutonhora kwekugadzira. Zvinotora mukana wakazara wezvakanakira kupisa kwekugadzira uye kutonhora kwekugadzira zvakateerana. Iyo simbi iri munzvimbo inopisa ine plastiki yakanaka uye yakaderera kuyerera kushushikana, saka iyo huru deformation process inopedzwa nekupisa kwekugadzira. Iko kurongeka kwekutonhora kwekugadzira kwakakwira, saka zviyero zvakakosha zvezvikamu zvinozogadzirwa nekutonhora kwekugadzira. Kupisa kwekugadzira-kutonhora kuumba komputa yepurasitiki yekugadzira tekinoroji yakaonekwa muma1980s, uye yave ichinyanya kushandiswa zvakanyanya kubva kuma1990s. Zvikamu zvakagadzirwa neiyi tekinoroji zvakawana mhedzisiro yakanaka yekuvandudza kurongeka uye kuderedza mutengo.
