TL;DR:Ukukhetha umoya ofanelekileyoumcu wentsimbi engagqwaliyo eqengqelekayo ebandayosesona sigqibo sibalulekileyo kwizinto ezisetyenziswayo ekunyatheliseni ngokuchanekileyo. Esi sikhokelo sithelekisa i-1/4H (ikota-hard), i-1/2H (isiqingatha-hard), kunye ne-Full Hard (FH) kwiimilinganiselo ezintlanu ezijolise kwisicelo — ukukwazi ukwakheka, i-springback, umgangatho womphetho, ubomi bokudinwa, kunye neendleko — sisebenzisa idatha yokuxinana, iziphumo zovavanyo olugobileyo ezivela kumzi-mveliso wethu eNingbo Stainless Steel, kunye nengxelo yasentsimini evela kwiivenkile zokunyathela kuzo zonke iimoto, izihlanganisi, kunye namashishini entwasahlobo.

Kutheni i-Hardness Temper yiParameter yokuQala yokuCacisa i-Precision Strip

Kwiminyaka eli-15 ndiphethe ubuchwephesha eNingbo Stainless Steel Co., Ltd., esona sikhalazo siqhelekileyo somgangatho endidibana naso asikokubala umgangatho — singobulukhuni. Njengomthengisi we-iimveliso zentsimbi engagqwaliyo eqengqelekayo ebandayo, Ndihlaziya imiba yomgangatho enxulumene nobushushu rhoqo ngeveki. Ivenkile yokunyathela iodola "i-304 stainless steel strip" kodwa ayichazi ukuba yintoni na i-temperament. Umzi-mveliso uthumela izinto ezithambileyo (ezithambileyo). Iidayi zokunyathela zivelisa amaqhuma. Ukusebenza kokugoba kudala i-springback engamkelekanga. Iinxalenye ziyasilela kwi-QC. Ityala liwela kumthengisi wezinto, kodwa unobangela yintloko yenkcazo yobushushu engekhoyo kuxwebhu lokuthenga.

I-cold-rolled stainless steel strip ifumaneka kwiindidi zobushushu ezichazwe yimigangatho ye-ASTM A240 kunye ne-JIS G4305, kunye nobunzima obuqala kwi-soft annealed (ngesiqhelo i-80–90 HRB okanye i-150–180 HV) ukuya kwi-full hard (ngesiqhelo i-30–38 HRC okanye i-350–400 HV). Ubushushu bufezekiswa ngokulawula ipesenti yokunciphisa ukuqengqeleka okubandayo kunye nomjikelo wokugqibela wokugxobeleka. Kwizicelo zokunyathela ngokuchanekileyo, ii-tempers ezintathu ezichazwe rhoqo yi-1/4H, 1/2H, kunye ne-Full Hard (FH). Nganye ithatha indawo ethile kwi-curve yokuma-nxamnye namandla, kwaye ukukhetha engalunganga kubiza imali kwiindawo ezilahliweyo, ukuguguleka kwezixhobo, okanye iindleko zezinto ezigqithisileyo.

Esi sikhokelo sibonisa indlela yokukhetha endiyisebenzisayo xa ndicebisa iinjineli zokuthenga. Sakhiwe ngokwemilinganiselo emihlanu ehambelana ngqo neziphumo zemveliso.

Uluhlu loBulukhuni kunye nothelekiso lwePropati yoMechanical

Itheyibhile engezantsi ishwankathela iimpawu eziqhelekileyo zoomatshini ze-304 stainless steel strip kwiqondo ngalinye lobushushu, ngokusekelwe kumaxabiso omda we-ASTM A240 kunye novavanyo lokuxinana ngaphakathi kwimigca yethu yemveliso:

Utshintsho olusisiseko lubonakala kuzo zonke iikholamu ezintathu: njengoko ubulukhuni busanda, amandla okutsalwa kunye nokukhupha ayanda, kodwa ukunwebeka - kwaye ke ngoko ukwakheka - kwehla kakhulu. Ukukhetha umoya ochanekileyo kuthetha ukufumana indawo kule ngqimba apho iimfuno zokwakheka kwenxalenye zifezekiswa ngaphandle kokuhlawula amandla angeyomfuneko okanye ukubandezeleka ngenxa yokungakheki kakuhle.iimveliso zemicu yentsimbi engagqwaliyo ezibonisiweyoNdiza kugubungela yonke i-spectrum yobunzima obuvela kwi-annealed nge-FH, kwaye ndihlala ndicebisa abathengi ukuba bavavanye isampuli ye-coil kumgca wabo wemveliso ngaphambi kokuba bazibophelele kwi-bulk volume.

Ubungakanani bokusetyenziswa 1: Ukubumbeka — Ukuzoba okunzulu, ukugoba, kunye nokuFlangisha

Imfuneko yokwakheka yeyona nto inzima ekukhetheni i-temperature. Ukuba umsebenzi wokunyathela ubandakanya ukuzoba okunzulu (umlinganiselo wokutsalwa > 1.8), ukwakheka okuntsonkothileyo kwamanyathelo amaninzi, okanye ukugoba kwe-radius eqinileyo ngaphantsi kwe-1.5 × ubukhulu bezinto, ukhetho lwe-temperature lunyanzelwa ukuba luye kwicala elisezantsi lesikali sobunzima.

1/4H — Ikhethwa xa imile kakuhle.Ngobude obuyi-25–40% kunye nokukwazi ukugoba ngo-180° ngaphandle kokuqhekeka (i-0t bend radius), i-1/4H lukhetho oluqhelekileyo lweendawo ezifakwe isitampu ezidibanisa ukwakheka neemfuno zamandla. Izicelo eziqhelekileyo ziquka: izixhobo zebracket zeemoto ezinezigaba ezininzi zokugoba, iiphaneli zombane ezinemiphetho ejikelezileyo, kunye neendawo zokusika izixhobo ezifuna ukubonakala okugudileyo emva kokwakheka.

1/2H — Ifanelekile ukwakheka okungajulileyo kwaye inamandla aphezulu.Ukwandiswa kwe-10–20% kuvumela ukugoba kwe-90° kwi-radius ye-1t kunye nokwakheka kwe-flange okuphakathi. Amandla aphezulu okuvelisa athetha ukuba inxalenye eyenziweyo igcina imo yayo ngcono emva kokukhupha kwi-die. Izicelo eziqhelekileyo: ii-spring clips, ii-contact terminals zezihlanganisi, kunye nemicu yoqhagamshelwano lwebhetri apho ukugoba okuphakathi kulandelwa ngumsebenzi we-elastic.

Iqinile Kakhulu — Ayikwazi ukwakheka; isetyenziselwa imisebenzi engenanto iflethi kunye neyokubhoboza.Xa ubude bungaphantsi kwe-6%, izinto ze-FH azinakugotywa okanye zitsalwe ngaphandle kokuqhekeka. Zichazwe kwiindawo eziveliswa ngokubhoboza, ukugquma, okanye ukucheba kuphela — akukho nyathelo lokwenza. Imizekelo: iiblade zesarha, iiblade zescraper, i-shim stock, kunye nezinto zentwasahlobo ezithe tyaba ezibunjwe ngokunyathela ukusuka kumcu othe tyaba ngaphandle kokugoba okulandelayo.

Ngokwembono yokuthenga, ukuba umzobo wenxalenye yakho uquka nayiphi na irediyasi yokugoba encinci kune-3t, iFull Hard ayilokhetho. Ukuba ibandakanya ukugoba kwi-1.5t okanye ngaphantsi, i-1/4H lukhetho olukhuselekileyo. Kuphela xa ukugoba kukwi-2t okanye ngaphezulu kwaye inxalenye ifuna ukuqina kokuthwala umthwalo kufuneka ucinge nge-1/2H. Ababoneleli bemicu yoshishino abanjengoiifektri ezikhethekileyo zokuchwetheza ngokuchanekileyobanikezela ngengqiqo efanayo yokukhetha ubushushu kumaxwebhu abo obuchwephesha, beqinisekisa ukuba i-1/4H yeyona ndawo icetyiswayo kakhulu yokuqalisa abathengi abaqalayo ukunyathela ngokuchanekileyo.

Ubukhulu besicelo 2: Imbuyekezo yeSpringback kunye noZinzo lweDimensional

I-Springback yindlela ethambileyo yokubuyisela izinto emva kokuba umthwalo wokunyathela ukhululwe. Ii-temperature zokuqina okuphezulu zinamandla aphezulu okuvelisa, nto leyo ethetha ukuba i-springback eninzi - kwaye kufuneka imbuyekezo engaphezulu kuyilo lwedayi.

Iqela lethu lemveliso lenze uvavanyo lwe-springback olulawulwayo lisebenzisa i-304 strip enobukhulu obuyi-0.5 mm kwi-temporers ezintathu, igobile kwi-engile ye-90° kwi-V-die ene-2 ​​mm punch radius:

Ukuze kunyatheliswe ngokuchanekileyo apho ukunyamezelana kobukhulu buyi-±0.1 mm phezu kwento eyenziweyo, izinto ze-1/4H zinokufikelela kujoliso ngaphandle kwemisebenzi yesibini. I-1/2H ifuna imbuyekezo yokugoba ngaphezulu kwidayi okanye inyathelo lokugoba ezantsi kwe-stroke.Izikhokelo zobugcisa zokuthenga imicu yentsimbi engagqwaliyoCebisa ukuqinisekisa indlela yokuziphatha kwe-springback kwizixhobo zokuvelisa zokwenyani ngaphambi kokuba ugqibezele iinkcukacha zobushushu, kuba i-die geometry kunye ne-lubrication zombini zichaphazela ubukhulu be-springback ngaphandle kobunzima bezinto ezibonakalayo. I-Full Hard ayisebenzi ngokufanelekileyo kuyo nayiphi na into egobileyo kwi-precision stamping - i-springback inkulu kakhulu kwaye iyaguquguquka kakhulu kulawulo oluhambelanayo lwemilinganiselo.

Ndicebisa iinjineli zokuthenga ukuba zixelele umyili wedayi ngemfuneko ye-springback ngaphambi kokuba zigqibezele i-temperament spec. Ukuba idayisi sele yakhelwe i-temperament ethile kwaye uzama ukutshintsha into eqinileyo, iindawo ziya kuhlala zingaphumeleli ekuhlolweni ngenxa ye-springback.

Ubungakanani besicelo 3: Umgangatho womphetho emva kokubhoboza nokuqhawula

Umgangatho womphetho wokucheba oveliswa yistamping — ingakumbi umlinganiselo wendawo yokucheba ecocekileyo kunye nendawo yokuqhekeka kumphetho otyumkileyo — uchatshazelwa ngokuthe ngqo bubunzima bezinto. Iziphumo zethu zovavanyo kwi-1.0 mm 304 strip kwiimo ezahlukeneyo zibonisa ipateni ecacileyo:

• 1/4H:Indawo yokucheba ecocekileyo = 55–60% yobukhulu bezinto. Izinto ezithambileyo ziyaguquguquka ngakumbi ngaphambi kokuba ziqhekeke, nto leyo evelisa indawo enkulu evuthayo kunye ne-die roll encinci. Nangona kunjalo, ii-edge burrs zibonakala kancinci ngenxa yokuguquguquka kwezinto.
• 1/2H:Indawo yokucheba ecocekileyo = 45–50%. Ubulukhuni obuphezulu buyanciphisa indawo yokuguqulwa kweplastiki, nto leyo enika umphezulu wokuqhekeka ococekileyo kodwa kubekho i-die roll eninzi kwicala lokungena. Ukuphakama kwe-Burr ngokuqhelekileyo yi-0.02–0.05 mm kwi-sharp die.
• Inzima Kakhulu:Indawo yokucheba ecocekileyo = 30–40%. Izinto eziqhekekileyo zaphuka ngaphambili kwi-punch stroke, nto leyo evelisa umphezulu womphetho oqhekekileyo onommandla omncinci wokutsha. Ukuphakama kwe-Burr yeyona iphantsi (0.01–0.03 mm) kodwa ukuthe tye komphetho nako kuphantsi kakhulu.

Kwizicelo apho umgangatho womphetho ubaluleke kakhulu ngokwembonakalo — njengemicu yokuhombisa ebonakalayo okanye iiphaneli zokuhombisa — i-1/4H okanye i-1/2H ivelisa inkangeleko engcono yomphezulu. Kwiindawo ezisebenzayo apho ukuchaneka kobukhulu bomfanekiso ongenanto kubalulekile, kwaye inkangeleko yomphetho ikwindawo yesibini, umoya oqinileyo unika ukucheba okucocekileyo kunye nokungagcobi kakhulu.

Ubungakanani besicelo 4: Ubomi bokudinwa kwiinxalenye ezinesitampu ezithwala i-cyclic

Iindawo ezifakwe isitampu ezifumana umthwalo ophindaphindiweyo — iisprings, iikliphu, iminwe yokudibanisa, kunye nezinto ezivalayo — zifuna ingqalelo ekhethekileyo ekukhetheni i-temperature. Uvavanyo lwethu lokudinwa ngaphakathi (ASTM E466, R = 0.1, 10 Hz) kwiisampuli ze-cantilever beam ezingama-304 ezifakwe isitampu zibonise iiprofayili ezahlukeneyo zokusebenza kokudinwa:

• 1/4H:Umda wokudinwa kwimijikelo eyi-10⁷ = 220 MPa. Ukudibana kokuguquguquka kunye namandla aphakathi kunika ukumelana okuhle kokuqalisa ukuqhekeka. Nangona kunjalo, izinto ezithambileyo zisengozini enkulu yokonakala komphezulu ngexesha lokuphathwa, nto leyo enokubangela ukuqhekeka kokudinwa.
• 1/2H:Umda wokudinwa kwimijikelo eyi-10⁷ = 290 MPa. Umlinganiselo ophezulu wamandla ukuya kubunzima wenza i-1/2H ibe lolona khetho lubalaseleyo kwiindawo ezixineneyo ezixineneyo. Umda wokunyamezela umalunga ne-38% yamandla okutsalwa, ohambelana nokuziphatha okuqhelekileyo kokudinwa kwentsimbi engagqwaliyo.
• Inzima Kakhulu:Umda wokudinwa kwimijikelo eyi-10⁷ = 200 MPa (uqhekeko lomphezulu lulawulwa). Nangona amandla aphezulu okutsalwa, izinto ze-FH zinokumelana nokudinwa okuncinci kuba iziphene zomphezulu — kuquka nomphetho wokucheba — zisebenza njengeendawo zokuqala ukuqhekeka. Ukuqina kokuqhekeka kuncitshisiwe kweli nqanaba lobunzima.

Isifundo esisebenzayo: kwizipringi kunye neekliphu ezifakwe ngokwezibalo (amawaka eebhayisikile), i-1/2H inika ukusebenza okugqwesileyo kokudinwa. Kwiindawo ezibalulekileyo kukhuseleko kwaye zidlula kwizigidi zemijikelo, cinga ukuba le ndawo ingayilwa ngamandla e-1/4H kunye necandelo elikhulu, kuba inzuzo yokudinwa kwamandla aphezulu okutsalwa iyapheliswa kukuncipha kokunyamezelana kweziphene.

Umlinganiselo wesicelo 5: Ukusebenziseka kweendleko kunye noLawulo lweZibonelelo

Umahluko weendleko phakathi kobushushu awukho kakhulu kwizinto ngokwazo — ixabiso lentsimbi esisiseko liyafana kwinqanaba elithile. Umahluko weendleko uvela kwimveliso evunyiweyo kunye nokufumaneka kwesibonelelo:

• 1/4Hyeyona nto isetyenziswa kakhulu kubathengisi be-stainless strip. Amaxesha okufumana i-lead kwi-warehouse yethu adla ngokuba yi-1-3 yeentsuku zokusebenza. Ngenxa yokuba i-1/4H yinkqubo yokunciphisa kancinci, i-rolling mill throughput iphezulu, kwaye iindleko zemveliso ngetoni nganye ziphantsi malunga ne-5-8% kune-FH.
• 1/2HIxabiso layo linokufumaneka ngokulinganayo kwi-1/4H kwiimarike ezinkulu. Ixabiso layo liphantsi kakhulu — ngesiqhelo liyi-2–3% ngaphezulu kwe-1/4H ngenxa yeemfuno zolawulo lwenkqubo ezingqongqo.
• Inzima Epheleleyo (FH)ifuna ucwangciso olucokisekileyo lomatshini wokugaya kuba ukunciphisa ukubanda okuphezulu (50%+) kuvelisa ubushushu obukhulu ngexesha lokuqengqeleka kwaye kufuna ukudlula rhoqo kwe-anneal ukuze kuthambeke phakathi. Amaxesha okukhokela adla ngokuba ziintsuku zokusebenza ezili-10-15 ngaphandle kokuba zigciniwe. Iprimiyamu yexabiso yi-10-15% ngaphezulu kwe-1/4H yokugqiba umphezulu olinganayo.

Kwabokuqala ukuthenga izinto zokunyathela ngokuchanekileyo, ndicebisa ukuba baqale nge-1/2H njengesiseko kwaye batshintshele kwi-1/4H kuphela ukuba umsebenzi wokwakha ufuna ukuguquguquka okungakumbi, okanye kwi-FH kuphela ukuba inxalenye iyinxalenye ethe tyaba engenanto efuna ubunzima obukhulu. Oku kunciphisa umngcipheko wokubonelela kwaye kugcina iindleko zezinto zikwindawo ephakathi efanelekileyo yoluhlu lobushushu.

Umzekelo oSebenzayo woBuchule: Indlela yokubhala iSiqendu seTemper kwi-RFQ yakho

Ukuqinisekisa ukuba umthengisi wakho unikezela ngobushushu obufunekayo, faka le nkcazelo ilandelayo kuxwebhu lwakho lokuthenga:

Iinkcukacha zezinto:I-304 Stainless Steel Strip, iCold Rolled

Uvavanyo:Ukujonga ubulukhuni kwikhoyili nganye — ukufundwa oku-3 kwikhoyili nganye, umyinge wengxelo kunye noluhlu

Ndicebisa ukuba le nkcazelo iqhotyoshelwe kuyo yonke i-RFQ, nokuba kusetyenziswe ii-odolo eziphindaphindwayo. Ixabiso lokufaka imigca emithathu eyongezelelweyo kwi-odolo yokuthenga li-zero. Ixabiso lokufumana umoya ongalunganga — ukuvala umgca, ukulungiswa kwedayi, ukubuyiswa kwezinto — lidlula ixabiso lezinto ngokwazo rhoqo.

I-Decision Matrix: Ukukhetha Umoya Ofanelekileyo kwiSicelo Sakho

Isiphelo

Ukukhetha phakathi kwe-1/4H, 1/2H, kunye ne-Full Hard cold-rolled stainless steel strip yokunyathela ngokuchanekileyo sisigqibo sobunjineli esinamacala amaninzi esingenakunciphisa sibe "sinzima singcono" okanye "sithambile sikhuselekile." Ngokuvavanya usetyenziso kuzo zonke imilinganiselo emihlanu - ukwakheka, ulawulo lwe-springback, umgangatho womphetho, ukusebenza kokudinwa, kunye neendleko zokubonelela - amaqela okuthenga angachaza umoya ochanekileyo ngokuzithemba.Intsimbi Engagqwaliyo yaseNingbo, sinikezela ngokulandelela ngokupheleleyo kobushushu, iingxelo zovavanyo lwe-mill, kunye nokuqinisekiswa kobunzima ngaphambi kokuthunyelwa kuyo yonkeumcu wentsimbi engagqwaliyo eqengqelekayo ebandayoiodolo, ukusuka kwiitoni ezi-1 zeesampulu ukuya kwiitoni ezili-100 zeemveliso. Ndicebisa ukuba ufake iinkcukacha zobushushu ngokucacileyo kwi-RFQ yakho kwaye ucele isatifikethi sobunzima esibhekisa kwi-ASTM A240 okanye kwi-JIS G4305 — yeyona ndlela ilungileyo yokuqinisekisa ukuba izinto ezihanjisiweyo zihambelana nezinto ezicatshulweyo.

Imibuzo ebuzwa qho

Yintoni umahluko phakathi kwe-1/4H, 1/2H, kunye ne-Full Hard stainless steel strip?

La manqanaba obushushu amiselwa yipesenti yokunciphisa umkhuhlane ngexesha lokuqengqeleka. I-1/4H (~11% yokunciphisa) inika ukwakheka okuhle kakhulu nge-HRB 88–96. I-1/2H (~21% yokunciphisa) ilinganisa amandla kunye nokwakheka okuphakathi kwi-HRB 96–104. I-Full Hard (~50% yokunciphisa) inika ubunzima obukhulu kwi-HRC 30–38 kodwa ayinakwenziwa — isetyenziselwa iindawo ezingenanto ezithe tyaba kuphela.

Ngaba umcu wentsimbi engagqwaliyo oqinileyo ungagotywa?

Izinto eziqinileyo ezipheleleyo zinobude obungaphantsi kwe-6%, oko kuthetha ukuba ziya kuqhekeka kuyo nayiphi na irediyasi egobileyo engaphantsi kobukhulu bezinto obuphindwe kathathu ukuya kahlanu. Kwiindawo zokunyathela ngokuchanekileyo ezifuna ukugotywa, i-1/4H okanye i-1/2H lukhetho olufanelekileyo. I-Full Hard kufuneka ichazwe kuphela kwimisebenzi yokugquma okanye yokubhoboza.

Yeyiphi i-temper efanelekileyo kwiikliphu zentwasahlobo ezifakwe istampu kunye nee-contact terminals?

I-1/2H (isiqingatha-iqinile) inika indibaniselwano engcono kakhulu yamandla okuvelisa, ukuqina kwentwasahlobo, kunye nobomi bokudinwa kwiindlela zokusetyenziswa kwentwasahlobo. Uvavanyo lwethu lokudinwa lubonisa ukuba i-1/2H inomda wokudinwa omalunga ne-290 MPa kwimijikelo ye-10⁷ — elona qondo liphezulu kwiindlela ezintathu zobushushu kwiindawo ezifakwe istampu ezijikelezayo.

Ndingaqinisekisa njani ukuba i-stainless steel strip iyasebenza?

Sebenzisa isixhobo sokuvavanya ubunzima beRockwell esiphathwayo (isikali seHRB se-1/4H kunye ne-1/2H, isikali seHRC seFH) kumphezulu ocociweyo nothe tyaba westrip. Okanye, uvavanyo lweVickers microhardness kwicandelo elinqamlezileyo lubonelela ngokufundwa okuchanekileyo ngakumbi. Cela isatifikethi sovavanyo lwemill esichaza uphawu lobushushu — i-ASTM A240 ifuna umthengisi ukuba axele ubunzima bobushushu ngabunye.

Ngaba ubushushu buchaphazela ukuxhathisa ukugqwala kwe-304 stainless steel strip?

Hayi — ukwakheka kweekhemikhali (18% Cr, 8% Ni) akutshintshi ngokwe-temperament. Nangona kunjalo, imeko yomphezulu inokwahluka: ii-temperament eziqinileyo zinokuba nomphezulu ongasebenziyo kancinci ukusuka kwinkqubo yokuqengqeleka, kodwa ukumelana nokugqwala kwinkonzo kuyafana kuzo zonke ii-temperament zomphezulu othile (2B, No. 4, okanye BA).

Zithini ii-odolo ezincinci ze-temper strip ezenziwe ngokwezifiso?

Kwi-1/4H kunye ne-1/2H yobushushu obuqhelekileyo (50–600 mm), i-MOQ idla ngokuba yi-1 metric ton ngobungakanani. Kwi-Full Hard, i-MOQ inokuba phezulu (iitoni ezi-3–5) ngenxa yeemfuno zokuhlela i-mill. Uninzi lwabasasazi lugcina i-standard temperature kwaye lunokubonelela ngamanani amancinci ngokulungiswa kwexabiso nge-kg nganye.
