Lub taub hau txias thiab txias nias yog chav tseem ceeb- cov txheej txheem kub txheej txheem siv rau hauv kev tsim cov fasteners thiab precision hardware Cheebtsam, qhov twg shaping ntawm workpiece tshwm sim tag nrho ntawm ambient kub; tus kheej-clinching screws, piv txwv li, feem ntau yog loj- tsim los ntawm cov txheej txheem tsim. Cov txheej txheem yuav tsum muab cov hlau dawb paug rau hauv qhov tshwj xeeb tuag thiab siv lub zog ntawm cov tshuab txias taub hau lossis cov xovxwm los tsav cov txheeb ze txav ntawm sab sauv thiab qis tuag. Qhov no ua rau qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob.
Hauv kev tsim khoom tiag tiag, kev sib sau txias ntawm fasteners tsis cia siab rau ib qho txheej txheem; kev tsim ntawm tus kheej -clinching bolts, piv txwv li, integrates cov yam ntxwv ntawm ob qho tib si txias taub hau thiab extrusion. Cov kev ua haujlwm txias ua haujlwm feem ntau suav nrog cov txheej txheem extrusion kom ua tiav qhov raug siab dua thiab cov qauv denser. Yog li ntawd, fastener txias taub hau yog suav hais tias yog cov txheej txheem sib xyaw ua ke uas sib xyaw ua kom muaj peev xwm nrawm nrawm ntawm lub taub hau txias nrog qhov kev ua tiav zoo ntawm extrusion.
Blanking yog ib qho tseem ceeb ua ntej- txheej txheem deformation hauv lub taub hau txias thiab yog siv dav hauv kev tsim khoom ntawm ntau tus kheej-clinching fasteners; Piv txwv li, qhov dawb paug shaping ntawm tus kheej -clinching compression screws cia siab rau cov txheej txheem no. Nws lub luag haujlwm tseem ceeb yog cais tag nrho ib feem ntawm qhov khoob ntawm lub cev loj. Cov ntawv thov feem ntau suav nrog txiav cov khoom siv raw hlau, ua ntej- xuas nrig ntaus qhov hauv cov txiv ntseej, thiab txiav lub taub hau ntsia hlau, yog li tsim kom muaj lub hauv paus tsis sib xws rau kev txiav txim siab tom ntej thiab shaping.
Kev ntxhov siab yog cov txheej txheem tseem ceeb hauv lub taub hau txias, feem ntau yog siv los ua kom zoo dua cov qauv ntawm qhov khoob; lub taub hau tsim ntawm clinching screws feem ntau siv cov txheej txheem no. Cov txheej txheem suav nrog kev siv lub tshuab tuag los siv lub siab, yog li txo qhov siab ntawm qhov siab thiab ua rau nws hla -sectional cheeb tsam. It is essential for key steps such as spherical upsetting for nuts and the pre-heading and finish-heading of bolt heads, effectively enhancing the workpiece's structural density and ensuring the fastener's structural integrity after forming.
Forward extrusion yog ib txoj hauv kev tseem ceeb rau precision txias taub hau thiab tsim nyog rau kev ua cov shanks ntawm ntau yam precision screws; lub shank txoj kab uas hla txo ntawm thawb-hauv clinching screws, piv txwv li, feem ntau siv cov txheej txheem no. Thaum lub sij hawm machining, cov hlau ntws nyob rau hauv tib txoj kev raws li lub Upper tuag lub zog. Txoj kev no feem ntau siv rau kev txo qis shank thiab txoj kab uas hla nqaim ntawm bolts thiab hex socket screws, tso cai rau kev tswj hwm ntawm qhov ntev ntev thiab txhim kho kev sib dhos haum.
Rov qab extrusion ua haujlwm nrog cov hlau ntws logic rov qab mus rau pem hauv ntej extrusion thiab feem ntau yog siv los tsim cov txheej txheem fastener geometries; lub taub hau tsim ntawm Revtex® tus kheej -clinching screws, piv txwv li, cia siab rau cov txheej txheem no. Thaum lub sij hawm shaping, cov hlau ntws nyob rau hauv lub opposite direction mus rau lub tuag lub zog. Feem ntau siv rau cov txheej txheem xws li tsim lub taub hau ntawm cylindrical hex socket screws thiab sib sib zog nqus kos duab, nws ua kom muaj txiaj ntsig zoo, kev sib xyaw ua ke ntawm txoj hauv kev, tsis yog - cov qauv duab.
Combined extrusion yog cov txheej txheem tseem ceeb rau siab -kawg precision fasteners, integrating qhov zoo ntawm ob qho tib si rau pem hauv ntej thiab rov qab extrusion; kev sib koom ua ke ntawm tus kheej -clinching studs feem ntau siv cov txheej txheem ua ke no. Ntawm qhov chaw ua haujlwm ib leeg, cov khoom ua haujlwm tau ua tiav ib txhij rau pem hauv ntej thiab rov qab hlau ntws-nrog qee cov hlau ntws mus rau pem hauv ntej nrog cov tuag kom txo tau txoj kab uas hla ntawm cov ncej, thaum lwm cov hlau ntws rov qab los ua lub taub hau-yog li ua tiav ntau- cov yam ntxwv tsim hauv ib qho kev ua haujlwm thiab ua kom muaj txiaj ntsig zoo thiab cov khoom raug.
Cov txheej txheem txias txias muaj cov txheej txheem ua tiav tshwj xeeb-npe, qhov tso cai ntawm cov hlau deformation- uas cuam tshuam ncaj qha rau cov khoom tiav tiav thiab kev tuag ntev; yog li ntawd, kev tsim khoom loj ntawm tus kheej -clinching threaded fasteners yuav tsum tau ua raws li cov qauv deformation. Yog hais tias lub taub hau txias deformation dhau ntawm cov hlau cov yas txwv, tsis xws luag xws li tawg los yog wrinkling tshwm nyob rau ntawm lub workpiece ob sab, uas ua rau cov khoom loj ntawm cov khoom tsis zoo thiab ceev tuag hnav- lossis txawm tias muaj kev puas tsuaj tuag vim tawg.
Lub plasticity ntawm cov khoom hlau ncaj qha txiav txim siab qhov tso cai deformation theem thiab ua lub luag haujlwm txiav txim siab hauv cov txheej txheem txias; Yog li ntawd, kev xaiv cov khoom siv rau threaded clinching screws yuav tsum ua raws li qhov sib thooj deformation tsis. Cov hlau nrog superior plasticity tuaj yeem tiv taus qhov txias dua deformation thiab muaj kev ua haujlwm siab dua. Piv txwv li, rau cov pa roj carbon steel, plasticity poob qis thaum cov ntsiab lus carbon nce, ua rau txo qis hauv kev tso cai deformation thiab muaj kev pheej hmoo siab ntawm kev tawg thaum ua tiav.
Rau cov ntaub ntawv nrog cov yas qis dua, xws li nruab nrab - carbon steel thiab alloy steel, kev lag luam tau tsim cov tswv yim zoo tshaj plaws rau kev ua kom zoo tshaj plaws los xyuas kom muaj kev ruaj khov ntawm ntau tus kheej -clinching fasteners; ua cov ntaub ntawv nyuaj rau tus kheej -clinching mounting screws yuav tsum tau tshwj xeeb ua ntej- kho. Kev ntsuas ntau lawm-xws li annealing kom soften cov hlau, optimizing tuag toughness, thiab txhim khu cov dawb paug nto lubrication- yog ua hauj lwm kom zoo ua rau cov hlau tso cai deformation thiab tiv thaiv tej teeb meem xws li workpiece cracking thiab tuag puas.
Zuag qhia tag nrho, kev sib xyaw ua ke txias taub hau thiab txias nias txheej txheem tau dhau los ua cov txheej txheem tsim khoom tseem ceeb rautus kheej-clinching mounting screws, ua tsaug rau nws qhov zoo ntawm kev ua haujlwm siab, precision, thiab kev sib xyaw ua ke. Cov txheej txheem encompasses tsib yam tseem ceeb deformation hom- blanking, chim siab, forward extrusion, rov qab extrusion, thiab ua ke extrusion- kom ua tau raws li qhov yuav tsum tau ua ntawm workpieces nrog ntau yam structural designs. Tsis tas li ntawd, nruj me ntsis tswj qhov kev tso cai ntawm cov hlau deformation thiab optimizing cov txheej txheem raws li cov yam ntxwv ntawm cov khoom yog ib qho tseem ceeb rau kev txhim kho cov khoom yield, txo cov nqi ntau lawm, thiab ncua sij hawm tuag; qhov no tuav tus nqi tseem ceeb rau precision fastener manufacturing kev lag luam.
Thov koj xav tiv tauj peb rau cov ntaub ntawv ntawm cov txheej txheem parameter hloov, cov khoom siv sib haum xeeb daws teeb meem, thiab cov tswv yim rau kev tswj deformation, thiab tau txais kev cob qhia kev tshaj lij ntawm cov txheej txheem kho vajtse precision.
