Ukugoba insimbi yensimbi engagqwali kuveza izinselele eziyingqayizivele eziyenza ihluke ekusebenzeni ngensimbi ethambile noma i-aluminium. Amandla aqinile wezinto ezisetshenziswayo, izici ezishiwo ze-springback, kanye nokuthambekela kokuqina komsebenzi kudinga amasu akhethekile nokuhlela ngokucophelela ukuze kuzuzwe imiphumela yobungcweti.
Lo mhlahlandlela obanzi uhlola izimiso ezibalulekile, izindlela, kanye nemikhuba engcono kakhulu yokugoba ngempumelelo insimbi yensimbi engagqwali kuzo zonke izinhlelo zokusebenza nobubanzi obugqinsi.
Ukuqonda Izakhiwo Zensimbi Engagqwali Yeshidi Lensimbi
Yini eyenza insimbi engagqwali ihluke
Insimbi engagqwali iqukethe ubuncane be-chromium engu-10.5%, eyenza ungqimba lwe-oxide oluvikelayo olunikeza ukumelana nokugqwala okuhle kakhulu. Le nqubo ye-alloying iphinda inyuse amandla kanye nobulukhuni bento esetshenziswayo uma iqhathaniswa nensimbi ye-carbon, ikwenze kube inselele kakhulu ukugoba.
Amabanga asetshenziswa kakhulu ukugoba insimbi yeshidi ahlanganisa:
I-304 Stainless Steel : Inikeza i-ductility enhle ne-springback emaphakathi, iyenze ifanelekele umsebenzi wokwakha ojwayelekile
I-316 Stainless Steel : Iqukethe i-molybdenum yokumelana nokugqwala okuphakeme kodwa idinga amandla aphezulu okugoba ngenxa yamandla angeziwe.
I-430 Stainless Steel : Ibanga le-ferritic elithengeka kakhulu kodwa elincane kune-austenitic grade
Ukucatshangelwa kokuqina kanye ne-Gauge
Ubukhulu bezinto ezibonakalayo buthinta ngokuqondile ubunzima bokugoba kanye nokukhetha kwesu:
Amashidi azacile (20-22 gauge, 0.8-0.9mm): Afanele ukugotshwa okwenziwa ngesandla ngamathuluzi ayisisekelo
Ugqinsi olumaphakathi (igeji engu-16-18, 1.2-1.6mm): Imvamisa idinga usizo lokushisa noma okokusebenza kwamanzi
Amashidi awugqinsi (igeji engu-14 nangaphezulu, 2mm+): Idinga amabhuleki okucindezela okuqhutshwa ngamanzi kanye namathuluzi akhethekile
Ukuqonda lezi zici ezibalulekile kukusiza ukuthi ukhethe izindlela ezifanele zokugoba zensimbi zephrojekthi yakho.
Izimiso Eziyinhloko Zokugoba Zensimbi Engagqwali
Izidingo ze-Bend Radius
Irediyasi encane yokugoba yensimbi engagqwali ngokuvamile isukela ku-1x iye ku-3x ubukhulu bezinto ezibonakalayo, kuye ngebanga nogqinsi. Ukusebenzisa irediyasi eqine kakhulu kungabangela:
Izibalo ze-K-Factor kanye ne-Bend Allowance
Izibalo ezinembile zemvume yokugoba ziqinisekisa ubude bezinto ezifanele nokunemba kobukhulu. Ifomula ejwayelekile ithi:
BA = (π/180) × B × (IR + K × MT)
Kuphi:
BA = Isibonelelo sokugoba
B = I-engeli yokugoba ngamadigri
IR = Irediyasi yangaphakathi
K = K-factor (imvamisa engu-0.33 yensimbi engagqwali)
MT = Ubukhulu bezinto ezibonakalayo
Ukuze uthole i-90-degree bend ku-3mm ugqinsi lwensimbi engu-304 engagqwali enerediyasi engu-3mm yangaphakathi:
BA = (π/180) × 90 × (3.0 + 0.33 × 3.0) = 6.91mm
Ukuphatha Springback Effects
Insimbi engagqwali ibonisa i-springback engaphezulu kakhulu kune-carbon steel ngenxa yezakhiwo zayo ezinwebekayo. I-springback evamile isukela ku-1-3 degrees, edinga ukugoba ngokweqile ukuze kuzuzwe i-engeli yokugcina oyifunayo. Imishini yesimanje yokugoqa yensimbi yeshidi le-CNC ihlanganisa izici zesinxephezelo esizenzakalelayo se-springback.
Izindlela Zokugoba Insimbi Yeshidi Lensimbi Engagqwali
Ukugoba Isandla Sezinto Ezibalulekile
Ukugoba ngesandla kusebenza ngempumelelo kumashidi afinyelela ku-20 gauge (0.9mm) ukujiya. Le ndlela idinga:
Amathuluzi Abalulekile:
Ibhuleki eligobayo noma i-jig yokhuni eqinile
I-rubber mallet

Ukusetshenziswa kokushisa kufanele kube okufanayo emgqeni wokugoba ukuvimbela ukugxila kwengcindezi kanye nokuqhekeka okungenzeka.
Ukugoqa kwama-Roll for Large Radius Curves
Imishini yokugoba idala amajika abushelelezi kanye nokuma okuyisilinda ngokudlulisa okubalulekile kumarola alungisekayo. Le ndlela isebenza kahle kakhulu ku:
Amajika erediyasi amakhulu adlula amandla okucindezela amabhuleki
Amajika amade, aqhubekayo
Izingxenye ze-cylindrical njengamapayipi noma amathangi
Ukugoqa Isinyathelo Sezimo Eziyinkimbinkimbi
Ukugoba isinyathelo kuhlanganisa ukudala amagoba amancane amaningi ngokulandelana ukuze kuzuzwe amajika erediyasi amakhulu noma amaphrofayili ayinkimbinkimbi. Le nqubo ivumela abaqambi ukuthi benze izimo ezingenakwenzeka ngokugoba kwephasi eyodwa.
