1 Kodi kupindika kwachitsulo ndi chiyani?
Kupinda ndi njira yopindika ndipo ndi imodzi mwazinthu zitatu zazikulu popanga zitsulo;ena awiri akudula ndi kulumikiza.Njira yopindika yopangira zitsulo ndi njira yopangira zitsulo zachitsulo mumiyeso itatu pogwiritsa ntchito zida zokakamiza komanso kufa kwapadera.Chifukwa cha zinthu zosiyanasiyana, makulidwe, kutalika ndi m'lifupi mwa pepala zitsulo komanso mawonekedwe osiyanasiyana ndi ngodya kupanga, matani ndi makulidwe a zida kuthamanga zida kupinda makina osiyana, komanso kutalika, mawonekedwe ndi V- matalikidwe kukula chapamwamba ndi m'munsi amafa, ndi awo apadera kufa akalumikidzidwa ndi osiyana.Nthawi zambiri amagwiritsidwa ntchito kutembenuza magawo azitsulo athyathyathya kukhala V-woboola pakati, U-woboola pakati kapena slotted.
2 Chida chopinda chachitsulo chopindika
Chida chofunikira kwambiri chopinda chachitsulo ndi brake, yomwe imabwera mosiyanasiyana.
- A gable brakendi makina opindika osavuta - komanso mabuleki omwe amagwiritsidwa ntchito kwambiri popanga - omwe amamangirira chinsalu chachitsulo pamalo athyathyathya ndiyeno amagwiritsa ntchito mphamvu kudzera pakuyenda kwa tsamba lopindika kuti apange mapindikidwe owongoka kapena ma creases osavuta.
- Makina opindikandi mtundu wa makina opindika omwe amagwiritsa ntchito nkhonya yosuntha ndi kufa kofananira.Pochita izi, pepala lachitsulo limayikidwa pakufa ndipo nkhonya imakakamizika kusunthira muzitsulo, ndikuyiyika mukufa.Kutengera mawonekedwe a kufa, makina opindika angagwiritsidwe ntchito kupanga ma V-bend, U-bend ndi mawonekedwe ena.
- Mabuleki a bokosi(omwe amadziwikanso kuti mabuleki a zala) ndi mtundu wina wa makina opindika omwe amagwiritsa ntchito mzere wachitsulo "zala" kupanga mapindikidwe angapo.Monga momwe dzinalo likusonyezera, mabuleki amabokosi amagwiritsidwa ntchito kupanga mabokosi akulu akulu.
- Makina opukutira barndi makina ang'onoang'ono komanso osavuta opindika okhala ndi chogwirira chomwe chimagwira chinsalu chachitsulo ndikuchipinda mosasunthika.
Mitundu ya 3 Yopindika Chitsulo cha Mapepala
Pali mitundu yosiyanasiyana yopindika zitsulo zomwe zimagwiritsidwa ntchito kuti zitheke mosiyanasiyana m'njira zosiyanasiyana.Njira zitatu zopindikazi (kupindika kwa mpweya, kuyika pansi ndi kuyika ndalama) Njira zokhotakhota zachitsulo ndizofanana chifukwa cholinga chawo chachikulu ndikutembenuza mawonekedwe achitsulo kukhala mawonekedwe omwe akufuna.Komabe, amasiyana mu ntchito yawo.Kumvetsetsa momwe mungapindire chitsulo chachitsulo kumafuna kumvetsetsa zinthu monga makulidwe azinthu, miyeso yopindika, utali wopindika wachitsulo ndikugwiritsa ntchito komwe kumatsimikizira njirayo.
1) Kupindika kwa Air
Kupinda kwa mpweya ndi njira yopindika yomwe nkhonya imakankhira chitsulo mukufa, koma osati motalikirapo kuti ikhudze makoma a kufa.
Njirayi si yolondola ngati ina, koma imasinthasintha kwambiri: ingagwiritsidwe ntchito kupanga V, U ndi maonekedwe ena a bend.Izi zili choncho chifukwa geometry yakufa sifunikira kugwirizana ndendende ndi bend yachitsulo yomwe mukufuna, chifukwa palibe kulumikizana pakati pazigawo ziwirizi.
2) Kutsika pansi
Kuyika pansi ndi njira ina yopindika.Pakugwedeza pansi, nkhonyayo imakanikiza zitsulo zonse mu kufa, ndikupanga bend yomwe imagwirizana ndi geometry mkati mwa kufa.Amagwiritsidwa ntchito popanga ma bend okhala ngati V.
3) Coining
Coining ndi mtundu wokwera mtengo kwambiri wopindika momwe nkhonya imatsitsidwa ndi mphamvu yayikulu muzitsulo zachitsulo ndi kufa, zomwe zimapangitsa kuti pakhale kusinthika kosatha komwe kumakhala ndi kasupe kakang'ono.
4) Kupinda
Kupinda kumatha kuchitidwa pamakina monga mabuleki a gable kapena makina opinda ndodo.Chitsulocho chimangiriridwa m'malo mwake mtengo wokhoma usanakwezedwe kuti upinde chitsulo kuzungulira mbiri.Kupinda kumapindika ngati V ndipo kumapangitsa kuti pakhale ma ngodya abwino kapena oyipa.
5) Kupukuta
Kupukuta (kapena kupindika m'mphepete kapena kupukuta) ndi njira ina yopinda yomwe imagwiritsidwa ntchito pamakina monga mabuleki a gable ndi makina opinda achitsulo (nthawi zina makina opinda).Ndiwofulumira kuposa kupukutira, koma ukhoza kuwononga kwambiri pepala lachitsulo pamwamba.
6) Kupindika kwa Rotary
Chifukwa cha makina omwe amagwiritsidwa ntchito, kupindika ndi njira yapadera kwambiri yopindika yachitsulo.Makina opindika opindika amakhala ndi ma cylindrical rollers omwe amapindika chitsulocho kukhala chopindika, kotero chitha kugwiritsidwa ntchito kupanga mapaipi, machubu ndi magawo ena ozungulira.
7) Kupindika kwa Joggle
Joggle kupinda (nthawi zina amatchedwa dimple kupinda) ndi njira yopinda pogwiritsa ntchito makina opindika omwe amakhala pafupi ndi kupindika kosalala (monga komwe kumapangidwa ndi kupindika).Pochita mapindikidwe angapo ang'onoang'ono ngati V motsatizana, Joggle kupindana kumatha kupanga mapindikidwe omwe amaoneka ngati mapindikidwe.
4Chilolezo Chopindika Mapepala ndi Njira Zowerengera
1) Chilolezo Chopinditsa Mapepala
Pamene pepala lachitsulo likupindika, kunja kwa bend kumatambasulidwa ndipo kotero miyeso yake imasintha.Izi zikutanthauza, mwachitsanzo, kuti kutalika kwa miyendo iwiri ya V-bend kudzakhala yaitali kuposa kutalika koyambirira kwa pepala.
Ndiye, ngati miyeso ikusintha, timapanga bwanji molondola gawo kuti tiwonetsetse kuti likugwirizana ndi zigawo zina?Kodi tingadziwe bwanji kutalika kwa pepala lachitsulo?Kubwezera kusintha kwa dimensional, tiyenera kuganizira zopindika: kusiyana pakati pa kutalika kwa mbale yovumbulutsidwa ndi kuchuluka kwa kutalika kwa mwendo uliwonse wa gawo lopindika lomalizidwa.
2) Mapepala achitsulo akutsegula chilinganizo chowerengera
Allowance yopindika.Kupindika kwachitsulo chopangidwa ndi zitsulo kumakhala ndi miyeso itatu: miyeso iwiri ya contour ndi kukula kwa makulidwe amodzi, ndipo miyeso iwiri ya contour imatanthauzidwa ngati L1 ndi L2, ndipo makulidwe ake ndi T. L1 + L2 ayenera kukhala aakulu kuposa kutalika kwake L. The kusiyana pakati pawo ndi gawo lopindika, lomwe limatanthauzidwa ngati K. Ndiye gawo losasinthika la bend L = L1 + L2-K.Mtengo wa K wa mbale yachitsulo yozizira kwambiri (yomwe ili: 90 degree bend, chida chopindika chokhazikika)
T=1.0 K=1.8
T=1.2 K=2.1
T=1.5K=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

Kupindika kwachitsulo pogwiritsa ntchito PROLEAN'TECHNOLOGY.
Ku PROLEAN TECH, timakonda kwambiri kampani yathu komanso ntchito zomwe timapereka kwa makasitomala athu.Chifukwa chake, timayika ndalama zambiri pazopita patsogolo zaukadaulo wathu ndipo tili ndi mainjiniya odzipereka omwe muli nawo.Lumikizanani nafe kwauleremawu.
Masomphenya a Prolean ndikukhala mtsogoleri wotsogolera pa On-Demand Manufacturing.Tikugwira ntchito molimbika kuti kupanga kukhala kosavuta, mwachangu, komanso kupulumutsa ndalama kuchokera ku prototyping mpaka kupanga.
