Iimvavanyo zokuqina, ezicinezelayo, zokugoba kunye nokucheba iiplastiki ezahlukeneyo, iirubha, kunye nemathiriyeli yentsimbi, kwaye inokusetyenziselwa uvavanyo loxinzelelo lwezixhobo ezingezizo ezentsimbi ezifana neeplastiki, ikhonkrithi kunye nesamente.Ukongeza izixhobo ezilula zinokugqibezela amatyathanga eteyiphu, iintambo zocingo, kunye nee-electrode ze-welding., iimvavanyo ezahlukeneyo zokusebenza kweethayile kunye namacandelo.Kufuneka ndenze ntoni ukuba ukubambelela komatshini wokuvavanya ukutyibilika?Umenzi womatshini wokuvavanya oqinileyo uya kuzisombululela yona.Into eqhelekileyo yomntu ibangela ukuba umatshini wokuvavanya i-tensile utyibilike kwaye into yomntu ebangela ukutyibilika komatshini wokuvavanya i-tensile ibangelwa kukungaphumeleli komsebenzisi ukwenza uvavanyo ngokwendlela echanekileyo ngexesha lovavanyo.Kukho izinto ezimbini eziphambili: Ubude bokulinganisa ubude bufutshane kwaye imihlathi yokubamba ayikhethwanga ngokufanelekileyo.1. Indlela echanekileyo yokusebenzisa i-clamp yomatshini wokuvavanya jikelele we-elektroniki kukusebenzisa amandla angaphandle ukutyhala imihlathi kwindawo yokubamba xa ubude be-clamping ye-specimen bufana nobude bendawo yezinyo le-clamp.I-friction force yokuqala, kwaye emva koko ilayishe isampuli ngokuhamba kwe-beam yomatshini wokuvavanya.Xa i-friction force itsala umhlathi (umlomo owenziwe nge-wedge), ngenxa yesenzo se-plane ethambekele, ubukhulu be-axial tension, ubukhulu be-clamping force iveliswa.Umatshini wokuvavanya wendalo yonke we-elektroniki Ngokukodwa, ukuvuleka okumise okwe-wedge kunye neendawo ezimbini ezithambekileyo zenzelwe ukufumana uxinzelelo olufanayo loxinzelelo ngokwendlela yokudibanisa ekhankanywe ngasentla.Nangona kunjalo, abanye abaqhubi abazange basebenze ngokuhambelana neemfuno zokusetyenziswa komatshini wokuvavanya, ubude bokulinganisa isampuli babufutshane, okanye inkqubo yesampulu yayimfutshane kakhulu, ekhokelela kumandla angalinganiyo kwindawo ethambekele yomlomo omise okwe wedge, kwaye uxinzelelo lwasekuhlaleni lomlomo olumise okwe-wedge lugqithise kakhulu Amandla esivuno sezinto, ukuze umlomo owenziwe nge-wedge uvelise i-deformation yeplastiki, i-eversion enzima, kwaye ibangela ukuba i-wedge-shaped mouth slope idilike okanye iguge.Kule meko, i-clamp iyaqhubeka isetyenziswa, inciphisa i-angle yomlomo owenziwe nge-wedge, ephazamisa imeko yoxinzelelo lomzimba we-clamp kwaye ibangele i-slippage.2. Ukukhethwa okungafanelekanga kwemihlathi yokulinganisa umatshini wokuvavanya, ebonisa ukuba umatshini wokuvavanya i-tensile uneentlobo ezahlukeneyo zenkcazo kunye neendawo zokugoba, kunye nemihlathi eyahlukeneyo isetyenziselwa iisampulu ezahlukeneyo.Abanye abaqhubi basebenzisa imihlathi emikhulu ngexesha lovavanyo.Ukubamba iisampulu ezinqamlezileyo ezincinci, okanye ukusebenzisa ii-chucks ezicaba ukuze ubambe iisampulu ezinkulu, kwenza unxibelelwano phakathi kwe-clamp kunye nesampulu ingavali, kwaye i-coefficient ye-friction iyancipha kakhulu.nciphisa.Xa amandla esampulu enyuka ngokuthe ngcembe ukuya kumandla amakhulu okukhuhlana okumileyo, isampulu iya kutyibilika, nto leyo ekhokelela kwisivuno sobuxoki ukusuka kumphezulu.

Okwesibini, izixhobo zibangela ukuba umatshini wokuvavanya u-tensile utyibilike Izizathu zezixhobo eziphambili kukuba isikali se-iron oxide siwela kwi-slope yebhlokhi ye-wedge xa ​​umatshini we-tensile utsala isampuli, ebangela ukutyibilika.Ngexesha lokuzoba isampuli yesinyithi, isikali se-oxide yesinyithi siyaveliswa, kwaye isikali se-iron oxide siya kuwela kwindawo ethambekele apho ibhloko enemilo ye-wedge kunye ne-fixture zidityanisiwe, ukuze ukuthambeka kwendawo ethambekele kutshatyalaliswe uburhabaxa bomphezulu buncitshiswe kakhulu, nto leyo eyenza umlomo omise okwe wedge (ibloko emile okwe wedge).) Intshukumo ayiguquguquki, kwaye xa amandla okutsala anyuka ngokuqhubekayo, ibhloko emile njenge-wedge iyatyibilika ecaleni kwe-dovetail slope ukuvelisa ukukhasa (ukutsiba).Le yindlela esiveliswa ngayo isandi sezigodlo nezigodlo esidla ngokwenzeka ebudeni benkqubo yokulayisha eqinile.Oku kudla ngokubizwa ngokuba kukutyibilika.Ulwazi lokugcinwa komatshini wokuvavanya i-tensile lubaluleke kakhulu kwinkqubo yethu yokusetyenziswa, kuba izixhobo zokuvavanya umatshini ziyingxenye esengozini, ngoko ke kufuneka sinikele ingqalelo kwizinto ezinjalo ngaphambi kokusetyenziswa!Makhe ndisasaze ukugcinwa komatshini wokuvavanya i-tensile kunye nolunye ulwazi olunxulumeneyo., enokunciphisa kakhulu ilahleko yokulungiswa.Umatshini wokuvavanya umatshini wokuvavanya imveliso yokudubula yokwenyani imifanekiso yokuvavanywa komatshini wokuvavanya ukugcinwa kwengqiqo eqhelekileyo: Ngaphambi kokusetyenziswa, khangela ukuba umatshini wokuvavanya uqinile uqinile kwaye unakho ukunyanzelisa umsebenzi;ukuba i-clamping surface igugile, yonakalisiwe okanye ihlanjululwe, i-clamping surface kufuneka itshintshwe ngexesha;Isixhobo siphantsi kovavanyo.Emva kokucoca izinto ezingaphezulu, kuya kukhuthazwa ukuze kungachaphazeli uvavanyo olulandelayo;i-fixture igcinwe kwaye ifakwe ngokufanelekileyo nge-glycerin ukukhusela i-rust;jonga rhoqo ukuba isixhobo sonakele;jonga rhoqo ukuba i-gauge yoxinzelelo irekhoda ngokuchanekileyo uxinzelelo lomoya kunye noxinzelelo lweoyile yesixhobo sokudibanisa;Inkqubo yokusetyenziswa Jonga ukuba umboniso uxhonywe ngokufanelekileyo kwaye ucinezelwe.Ukubamba okungafanelekanga kunokwenzeka ukuba konakalise ukubamba;musa ukusebenzisa amandla okubamba ngaphezulu koko kufunekayo.

Ngethuba nje inokubonelela ngokuthembekileyo, ukulungiswa kokungatyibiliki;i-specimen kwi-fixture kufuneka ihlale iqhotyoshelwe kwiseli yomthwalo;ukutshisa iseli yomthwalo ubuncinane imizuzu eyi-15;wakuba umboniso usendaweni, musa ukutshintsha ibhalansi okanye indawo yokulawula indawo yeBeam;sebenzisa umsebenzi wokukhusela umthwalo ukukhusela isampuli kumonakalo, ukuba umthwalo wesampuli ungaphantsi koluhlu, nceda ucinge usebenzisa iseli yomthwalo omncinci;uyilo lomatshini wokuvavanya i-tensile isekelwe ikakhulu kumgangatho wokuvavanya wezinto eziphathekayo kunye nesampuli (ngokukodwa kubhekiselele kwimilo kunye nezinto ezigqityiweyo kunye neemveliso ezigqityiweyo).Le migangatho ngokubanzi inemigaqo engqongqo kulungiselelo lwesampulu kunye neendlela zovavanyo, icebisa ukuba singayila izilungiso ezahlukeneyo ngokweisampulu ezahlukeneyo kunye neendlela zovavanyo.Ukulungiswa okusetyenziselwa iisampulu ezikhethekileyo (iimveliso ezigqityiweyo kunye neemveliso ezigqityiweyo), ukulungiswa kwenzelwe ubukhulu becala ngokwemilo kunye nezinto zesampulu.I-fixture ngokwayo ayinalo ulwakhiwo olusisigxina (umzekelo, ucingo lunokulimala, okanye iipleyiti ezimbini ezisicaba, kunye nesampuli yeplate yentsimbi ebhityileyo inokuba yi-wedge-shaped. Iyakwazi ukunyanzeliswa), nto leyo ngokucacileyo yahlukile kwinginginya.
