Ukuyila indawo yesitampu yentsimbi enokuveliswa ngokuthembekileyo nangexabiso elifanelekileyo ayifani nokuyila inxalenye "ebonakala ilungile" kwi-CAD. Isibiyeli esinemodeli egqibeleleyo kwiSolidWorks sinokuba sisilaphu esivelisa inkunkuma kumgangatho wokushicilela - ngenxa yokuba umyili ewuhoye umthetho weradiyasi egobileyo okanye ubeke umngxuma kufutshane kakhulu kumphetho.
Apha kulapho i-Design ye-Manufacturability yeDFM isetyenziswa kwi-DFM, uyilo olusetyenziswayo yemithetho eqinisekisiweyo-ethathwe kwizixhobo zefiziksi, ukuziphatha kwezinto, kunye namashumi eminyaka yamava omgangatho wevenkile-ukuqinisekisa ukuba indawo yakho inokufakwa isitampu ngokungaguqukiyo kumthamo wemveliso ngaphandle kokunxitywa kwezixhobo ezigqithisileyo, imiphetho eyahlulahlulwe, okanye idimensional drift.
Kwesi sikhokelo, uya kufunda imithetho emihlanu esisiseko yoyilo lwenxalenye yesitampu sentsimbi, izikhokelo zoyilo lwesitampu esinzulu soyilo lweejiyometri ezinde, indlela ibakala lemathiriyeli eliyalela ngayo ukhetho lwakho loyilo, ezona mpazamo zisixhenxe zixhaphakileyo zoyilo lwesitampu, ireferensi yonyamezelo olusebenzayo, kunye nokuhamba komsebenzi okupheleleyo ukusuka kwimodeli ye-3D yokuhlola kuqala.
Imithetho esisiseko yoYilo lweSitampu seNtsimbi
Minimum Bend Radius
Xa ugoba ishidi lesinyithi, umphezulu wangaphandle uyolula ngelixa umphezulu wangaphakathi ucinezela. Ukuba iradiyasi yokugoba iqine kakhulu xa kuthelekiswa nobukhulu besixhobo, iintsinga zangaphandle ziyakrazuka.
| Material | Ubuncinci obuCetyisiweyo Ngaphakathi kweBend Radius |
|---|---|
| Intsimbi eMild (CRS, HRPO) | 1.0 × ubukhulu bezinto (1T) |
| Stainless Steel (304, 316) | 1.5T – 2.0T |
| Aluminium (5052, 6061) | 1.0T – 1.5T |
| Ubhedu / iBrass | 0.5T – 1.0T |
| Spring Steel / Hardened | 3.0T – 4.0T |
Ukugoba ngaphaya komyinge weenkozo kufuna iradiyasi enkulu. Ukugoba okubalulekileyo, cacisa ulwalathiso lwengqolowa kumzobo kwaye ungeze i-50% kwi-radius encinci ukuba ukugoba kuguqa.
Digital Hole
Imingxuma ebethelelwe kufutshane kakhulu kumphetho wenxalenye iya kugqabhuka okanye ikrazule isiphelo ngaphandle.
- Kwimingxuma engaphantsi kwe-6 mm ubukhulu: dge5 ukusuka kwi-trimme 1.
- Kuba imingxuma 6–12 mm: ≥ 2.0T ukusuka emphethweni
- Kwimingxuma engaphezu kwe-12 mm: ≥ 2.5T ukusuka emphethweni
Gcina imingxuma ubuncinci be-2.5T + bend radius kude nakweyiphi na i-bend tangent line.
Ububanzi beSlot kunye neSithuba soMbambo
- Ububanzi Slot kufuneka ≥ 1.0T
- Ubude bendawo yokubeka akufunekanga budlule kwi-5 × ububanzi besithuba sepunch yesikhululo-sinye
- Iindawo zokubeka ezinxuseneyo kufuneka zohlulwe nge-≥ 2.0T yezinto eziphathekayo
- Ziphephe iikona ezibukhali zangaphakathi kwiindawo zokubeka — sebenzisa ubuncinci be-0.5 mm radius
Corner Ras
- Iikona zangaphandle: ubuncinci be-0.5T radius
- Iikona zangaphakathi: ubuncinane be-1.0T irediyasi, ngokufanelekileyo i-1.5T
- Iinowutshi zoncedo kwiindlela ezigobileyo: 1.0T ubuncinci berediyasi
Izikhokelo zoYilo lweSitampu soMzobo onzulu
Isitampu esinzulu yinkqubo yokuzoba isicangca esisicaba kwindawana engenanto apho ubunzulu bekomityi bugqithise umngxuma wokufa.
Zoba umlinganiselo
Elona nani libaluleke kakhulu: Zoba umlinganiselo (β) = I-Diameter engenanto / i-Punch Diameter
- Umzobo omnye: β ≤ 2.0 kwizinto ezininzi
- Intsimbi engenasici: β ≤ 1.8 kumzobo omnye
- Aluminium: β ≤ 1.7 kumzobo omnye
- Ukuba i-β > 2.0 inqanaba lomzobo eliphakathi elifunekayo
Limiting Draw Ratio (LDR)
| Material | LDR eqhelekileyo |
|---|---|
| DDQ Steel | 2.2 – 2.3 |
| 304 I-Stainless (i-annealed) | 2.0 – 2.1 |
| 5052 iAluminiyam (O-temper) | 1.8 – 1.9 |
| I-Copper (i-annealed) | 2.1 – 2.2 |
| Brass (70/30) | 2.0 – 2.1 |
Ukhetho lweMathiriyeli kunye nokuNgqwalasela koButyenene
| Material | Ukutyeba okuqhelekileyo (mm) | Ukuqwalaselwa koYilo oluPhambili |
|---|---|---|
| Intsimbi eRod-Rolled | 0.4 – 3.2 | Ukubumba okugqwesileyo; igophe eliqinileyo radii enokwenzeka |
| I-Stainless Steel 304/316 | 0.3 – 3.0 | I-springback ephezulu (ukuya kwi-3 × CRS); ifuna overbending |
| intsimbi engatyiwa 430 | 0.3 – 2.5 | Magnetic, i-springback engaphantsi kune-304 |
| I-Aluminiyam 5052-H32 | 0.5 – 3.0 | Ukwakheka okuhle, intwasahlobo ephakathi |
| Aluminium 6061-T6 | 0.5 – 3.0 | Ukungahambi kakuhle kwi-T6; qwalasela i-O-temper + post-form heat treatment |
| Copper C11000 | 0.3 – 2.0 | Excellent formability; ilungele umzobo onzulu |
Umkhombandlela weenkozo kufuneka usoloko uphawulwe kumzobo wakho xa indawo ine-tight-radius egobileyo.
Iimpazamo zoYilo lweStamping eziqhelekileyo
Impazamo 1: Imingxuma isondele kakhulu kwi-Bend Lines - Gcina ≥ 2.5T + ukugoba i-radius clearance. Cacisa ukugqobhozwa kwangethuba ukuba akunakuthintelwa. I-
Impazamo 2: Iikona zangaphakathi ezibukhali -Yongeza ubuncinci beradiyasi ye-0.5T kuzo zonke iikona zangaphakathi.
Impazamo 3: Ukunyamezelwa kwe-Flatness okungeyonyani - I-flatness egxininisiweyo yi-0.5% yobukhulu obude kwiindawo ezingaphantsi kwe-2mm ubukhulu.

Imibuzo Ebuzwa Rhoqo
Ngowuphi umlinganiselo wokugoba werediyasi yesitampu sentsimbi engenastainless?
Kwiintsimbi ezingenazintsimbi ze-austenitic ezifana ne-304 kunye ne-316, ubuncinci obucetyiswayo ngaphakathi kwi-radius yokugoba ukuya kwi-21. Xa ugoba ngapha kweenkozo, nyuka uye kwi-2.0T ukuya kwi-2.5T. Kumabanga aphakamileyo anamandla afana ne-301 egcwele nzima, sebenzisa i-3T ukuya kwi-4T.
Umngxuma unokusondela kangakanani emphethweni wenxalenye enesitampu?
Umgama osuka kwiziko lomngxuma ukuya kumngxunya okufutshane we-6T kufuneka ube ngaphantsi kwe-6T engaphantsi komphetho. 2.0T imingxuma 6-12mm, kunye 2.5T imingxuma phezu 12mm. Xa ukufutshane nomgca wokugoba, sebenzisa i-2.5T kunye neradiyasi egobileyo njengomgama omncinci.
Yintoni umahluko phakathi kwesitampu kunye nomzobo onzulu?
Isitampu ligama elibanzi eligubungela yonke imisebenzi yokwenziwa kwesinyithi - ukuvala, ukugqobhoza, ukugoba, ukwenza imali, kunye nokuyilwa nzulu. Umzobo onzulu yiseti ethile apho icwecwe elisicaba litsalwa ngokwe-radially kwidayi ukuvelisa ikomityi, inkonkxa, okanye iqokobhe elinobunzulu obungaphezulu kobubanzi bayo.
Yeyiphi ialloyi yealuminiyam eyona ilungileyo kumalungu anesitampu afuna ukugoba?
5052-H32 yeyona aluminiyam ialloy ekhethwayo kwiindawo ezinesitampu ezifuna ukwenziwa okubalulekileyo. Iphatha i-90 ° igobe kwi-1.0T ukuya kwi-1.5T radius ngaphandle kokuqhekeka. Gwema i-6061-T6 ngokugoba okuqinileyo - sebenzisa i-O okanye i-T4 intukuthelo nge-post-form yokuguga, okanye utshintshe kwi-5052-H32.
Ixabisa malini iprogressive die tooling?
Kuba isibiyeli sentsimbi elula (4-6 izitishi), $5,000-$15,000. Amacandelo amakhulu anezikhululo ze-8-12 kunye nokufakwa kwe-carbide: $ 20,000-$ 50,000 +. Umzobo onzulu wamanqanaba amaninzi ufela i-stainless: $ 80,000+. Lawa manani e-ballpark - ngenisa imodeli ye-3D yesicatshulwa esichanekileyo.
Ngaba ndingaluchaza ulwalathiso lwenkozo kumzobo wam wesitampu?
Ewe - kuyo nayiphi na indawo ene-bend radii engaphantsi kwe-2T yentsimbi okanye i-3T engenasici. Ukugoba ngeenkozo kuvumela i-radio eqinile kodwa i-springback eninzi; ngaphaya kweenkozo kufuna i-radii enkulu kodwa ivelisa ii-engile ezihambelanayo.
Ngaba iindawo ezinesitampu zinokudityaniswa emva kokwenza?
Ewe. Uninzi lwentsimbi enesitampu kunye namacandelo e-aluminiyam anokuthi adityaniswe nge-welding indawo yokumelana, i-MIG, i-TIG, okanye i-laser welding. Ukubonelela ngeeflange ezisicaba, ezifikelelekayo ezinobuncinci obuyi-8mm imvume ejikeleze indawo ye-weld ukufikelela kwi-electrode.
