Ukungabhali yenye yeyona misebenzi ibalulekileyo kwisitampu sentsimbi. Iguqula isinyithi esicaba okanye isitokhwe sekhoyili sibe ngamacandelo ahlukeneyo - abizwa ngokuba ziindawo ezingenanto - ngokucheba imathiriyeli ecaleni kwecontour evaliweyo usebenzisa ipunch kwaye ufe. Nokuba wenza izibiyeli, izibiyeli, unxibelelwano lombane, okanye iipaneli zemoto, inkqubo yokungabhalwanganto ibeka isiseko senxalenye yejometri, umgangatho wecala, kunye nemisebenzi yokwenziwa ezantsi komsinga.
Esi sikhokelo sigubungela ubuxhakaxhaka bokugquma, ukuba buhluke njani ekubetheni, iindlela ezinkulu zokuvala ezikhoyo, ukusetyenziswa kwezinto amaqhinga, iziphene eziqhelekileyo kunye nokulungiswa kwazo, kunye nokubalwa kweetoni ozifunayo kukhetho lokushicilela.
Yintoni Inkqubo yokuGlankitha?
Kwisitampu sesinyithi, ukuvala ngumsebenzi wokucheba apho inxalenye efunwayo isikwa kwiphepha kwaye iwela ngokuvula kufa njengeqhekeza eligqityiweyo. Izinto ezijikelezileyo - i-skeleton okanye iwebhu - iba yi-scrap. Olu luphawu oluchazayo olwahlula ukugquma ekubetheni (ukugqobhoza), apho i-slug esusiweyo sisilaphu kwaye iphepha ligcina umngxuma.
Indlela okusebenza ngayo ukucheba
Xa i-punch ihla kwaye idibanisa i-icwecwe lentsimbi, ukucheba kuqhubela phambili ngezigaba ezine ezihlukeneyo:
- deformation Elastic - Izinto eziphathekayo zixinzelela kancinci phantsi kwepunch tip; akukho tshintsho lwemilo esisigxina eyenzekayo okwangoku.
- deformation yePlastiki - I-punch ingena kwizinto eziphathekayo, iqalisa ibhendi etshisiweyo (egudileyo) enqamlekileyo kwicala elisondeleyo kwi-punch.
- Ukwaphuka - Iintanda zivela kwi-punch kwaye zife kwaye zisasazeke ngaphakathi. Apho imimandla emibini yokuphuka idibana khona, izinto eziphathekayo ziyahlukana.
- Ukwahlula — Isithuba esingenanto sisusa indawo yokufa. Izikhonkwane ze-Ejector okanye ii-strippers zityhala inxalenye okanye i-skeleton simahla.
Isiphumo secandelo elinqamlezileyo lenxalenye evaliweyo libonisa iindawo ezine iimpawu: i- rollover (ibhendi yokucheba phezulu), i tshisa indawo (ibhendi ethe nkqo egudileyo), i indawo yokwaphuka (rough angled surface), kunye burr (umlebe omncinci, obukhali kumda ongezantsi).
Usulelo: Eyona Parameter ibaluleke kakhulu
Die clearance - i-gap phakathi kwe-punch cutting edge kunye ne-die cutting edge elinganiswe kwicala ngalinye - ilawula ngokuthe ngqo umgangatho wecala, ukuphakama kwe-burr, kunye nobomi besixhobo.
| Ukucoca ngecala ngalinye (% of material thickness) | Iziphumo eziqhelekileyo |
