1 Chii chinonzi sheet metal bending?
Kupeta imhando ye deformation uye ndeimwe yematatu makuru maitiro mukugadzira simbi simbi;mamwe maviri ari kucheka nekubatanidza.Iyo shizha simbi yekugadzira yekubhenda maitiro ndiyo maitiro ekuumba pepa simbi kuita mativi matatu uchishandisa kumanikidza midziyo uye yakakosha inofa.Nekuda kwezvakasiyana zvinhu, ukobvu, kureba uye hupamhi hwepepa resimbi pamwe chete nemaumbirwo akasiyana uye makona ekuumba, matani uye saizi yemidziyo yekumanikidza yekupeta michina yakasiyana, pamwe nekukwirira, chimiro uye V- amplitude saizi yekumusoro uye yepasi inofa, uye yavo yakakosha maumbirwo ekufa akasiyana.Inowanzo shandiswa kushandura flat sheet simbi zvikamu kuita V-yakaumbwa, U-yakaita kana slotted.
2 Sheet simbi yekubhenda midziyo
Iyo yakakosha sheet simbi yekubhenda midziyo ndeye brake, iyo inouya nenzira dzakasiyana siyana.
- A gable brakemuchina wekupeta wakapfava - uye unonyanya kushandiswa mabhureki mukugadzira - unosungirira bepa resimbi panzvimbo yakati sandara uye wobva washandisa simba kuburikidza nekufamba kwebanga rinokwenya kuita mabhendekete akatwasuka kana makirisi nyore.
- Muchina wekupetaimhando yemuchina wekupeta unoshandisa chibhakera chinofamba uye chinofaya.Muchiitiko ichi, pepa resimbi rinoiswa pakufa uye punch inomanikidzwa kufamba musimbi, ichimanikidzira mufa.Zvichienderana nechimiro chefa, michina yekupeta inogona kushandiswa kugadzira V-mabhendi, U-mabhendi uye mamwe maumbirwo.
- Bhokisi mabhureki(inozivikanwawo semabhureki emunwe) ndeimwe mhando yemuchina wekupeta unoshandisa mutsara wesimbi "minwe" kugadzira mabhendi akawanda etsika.Sezvinoreva zita, mabhureki ebhokisi anowanzo shandiswa kugadzira mabhokisi akakura.
- Muchina wekupeta bhawakachina kadiki uye kakareruka kakapeta kane mubato unobata bepa resimbi uye worikotamisa kamwe chete.
3 Mhando dzeSheet Metal Bending
Kune marudzi akasiyana epepa resimbi kubhenda rinoshandiswa kuwana mabhendi akasiyana nenzira dzakasiyana.Nhatu dzeidzi nzira dzekupeta (kupeta kwemhepo, kudzika pasi uye kuisa mari) Nzira dzekukotamisa simbi dzakafanana pakuti chinangwa chavo chikuru ndechekushandura chimiro chesimbi simbi kuita fomu inodiwa.Zvisinei, vanosiyana mukushanda kwavo.Kunzwisisa nzira yekubhenda simbi yesimbi kunoda kunzwisisa kwezvinhu zvakaita sehukobvu hwezvinhu, kubhenda mativi, sheet simbi kubhenda radius uye kushandiswa kunotaridza nzira.
1) Air Bending
Kukotama kwemhepo inzira yekupeta iyo iyo punch inotsikirira simbi mufa, asi kwete kureba zvekuti inobata madziro efa.
Iyi nzira haina kururama sevamwe, asi inoshanduka-shanduka: inogona kushandiswa kugadzira V, U uye mamwe maumbirwo emabhendi.Izvi zvimwe nekuti iyo geometry inofa haidi kuenderana chaizvo neinodiwa simbi bend, sezvo pasina kubatana pakati pezviviri izvi.
2) Kudzika pasi
Kudzika pasi ndiyo imwe nzira yekupeta mabhendi.Munguva yepasi, punch inotsikirira simbi simbi zvachose mufa, ichigadzira bend rinoenderana nejometri mukati mekufa.Inoshandiswa kugadzira mabhendi akaita V.
3) Coining
Coining imhando inodhura yekubhenda umo chibhakera chinodzikiswa nesimba guru mushizha resimbi uye kufa, zvichikonzera deformation yekusingaperi ine zvishoma springback.
4) Kupeta
Kupeta kunogona kuitwa pamichina yakaita semabhureki egable kana michina yekupeta tsvimbo.Shereti simbi inosungirirwa panzvimbo danda rekusungirira risati rasimudzwa kukotamisa simbi ichitenderedza chimiro.Kupeta kunogonesa kubhenda kwakaita V uye kunobvumira makona ekubhenda akanaka kana asina kunaka.
5) Kupukuta
Kupukuta (kana kupeta mupendero kana kupukuta-kupeta) imwe nzira yekukotama inoshandiswa kumichina yakaita semabhureki egable nemichina yekupeta simbi (mune dzimwe nguva michina yekupeta).Inokurumidza kupfuura kupeta, asi inogona kukonzera zvakanyanya kukuvadza kune pepa resimbi.
6) Rotary Bending
Nekuda kwemuchina unoshandiswa, roll kupeta ingangove yakasarudzika pepa simbi yekukotama maitiro.Iyo roll bending system ine matatu cylindrical rollers anokotama simbi kuita chimiro chakakomberedzwa, saka inogona kushandiswa kugadzira mapaipi, machubhu uye zvimwe zvikamu zvakatenderera.
7) Joggle Bending
Joggle beng (dzimwe nguva inodaidzwa kunzi dimple bending) inzira yekupeta uchishandisa muchina wekupeta unosvika pakukotama (seuyo unogadzirwa nekupeta).Nekuita mabhendeti madiki akaita seV akateedzana, Joggle kukotama kunogona kuburitsa mabhende anoita semacurve.
4Sheet Metal Bending Allowance uye Calculation Techniques
1) Sheet Metal Bending Allowance
Kana pepa resimbi rakakotama, kunze kwebhendi rinotambanudzwa uye naizvozvo zviyero zvaro zvinoshanduka.Izvi zvinoreva, semuenzaniso, kuti hurefu hwakazara hwemakumbo maviri eV-bend huchave hwakareba kupfuura urefu hwepakutanga hwepepa.
Saka, kana zviyero zvikachinja, tinogadzirisa sei chikamu kuti tive nechokwadi chekuti chinokwana pamwe chete nezvimwe zvikamu?Tinosarudza sei kuti pepa resimbi rakati sandarara rinofanira kuva rakareba sei?Kuripira shanduko yedimensional, isu tinofanirwa kufunga nezve mvumo yekukotama: mutsauko pakati pehurefu hweplate yakavhurwa uye huwandu hwehurefu hwegumbo rega rega rechikamu chakapetwa chakapetwa.
2) Sheet simbi inovhurika calculation formula
Bending allowance.Pepa rakaumbwa resimbi bend rine mativi matatu: maviri contour dimensions uye imwe ukobvu dimension, uye maviri contour dimensions anotsanangurwa seL1 uye L2, uye ukobvu dimension ndeye T. L1 + L2 inofanira kunge yakakura kupfuura iyo yakavhurwa urefu L. The musiyano pakati pawo imvumo yekukotama, inotsanangurwa seK. Ipapo chiyero chakavhurwa chebhendi L=L1+L2-K.Iko kukosha kweK kwesimbi inotonhora yakatenderedzwa ndiro (mamiriro: 90 dhigirii bend, yakajairwa kubhenda chishandiso)
T=1.0 K=1.8
T=1.2 K=2.1
T=1.5 K=2.5
T=2.0 K=3.5
T=2.5 K=4.3
T=3.0 K=5.0
T=3.5 K=6.05
T=4.5 K=7.0
T=5.0 K=8.5

Sheet simbi inokotama nekushandisa PROLEAN'TECHNOLOGY.
PaPROLEAN TECH, isu tine shungu nekambani yedu uye masevhisi atinopa kune vatengi vedu.Saka nekudaro, tinodyara mari yakawanda mukufambira mberi kwazvino muhunyanzvi hwedu uye tine mainjiniya akazvipira kwauri.Bata nesu maharaquote.
Chiono chaProlean ndechekuve anotungamira mhinduro mupi weOn-Demand Manufacturing.Tiri kushanda nesimba kuita kuti kugadzira kuve nyore, nekukurumidza, uye kuchengetedza mari kubva ku prototyping kusvika pakugadzira.
