Imibuzo Ebuzwa Rhoqo
Loluphi unyamezelo olunokuthi lubambe isitampu sesinyithi?
Isitampu sentsimbi esiqhelekileyo sibamba i-± 0.10 mm kwimilinganiselo yomgca kunye ne-± 0.05 mm kwiidamitha zomngxuma. Ukuchaneka isitampu kufikelela ku-±0.025 mm kwiimpawu zomgca kunye ne-±0.013 mm emingxunyeni, kodwa kwiindleko eziphezulu zezixhobo kunye nokugcinwa. Ukuchaza unyamezelo oluqina kune-±0.025 mm ngokuqhelekileyo kufuna ukwenziwa kwesibini.
Ingaba kubiza malini izixhobo zesitampu sesinyithi?
Uluhlu lwezixhobo zokufa eziqhubekayo ukusuka kwi- $ 15,000 yesikhululo esilula se-3-5 sifa ukuya kwi- $ 250,000+ kwisikhululo esiyinkimbinkimbi sama-20+ sifa ngokucofa kwi-in-die okanye indibano. Ukufa okukodwa okanye okubaleka kancinci kuqala malunga ne-5,000 yeedola. Ixabiso lezixhobo lixhomekeke kubungakanani benxalenye, inani lemisebenzi, imathiriyeli yokufa (i-D2, i-carbide, okanye isinyithi esingumgubo), kunye nobomi obulindelekileyo bokufa (500,000 ukuya kwi-50+ million hits).
Ngowuphi ubungakanani obuncinane bomyalelo wokugximfizwa kwentsimbi?
Uninzi lwababoneleli ngezitampu lufuna ubuncinci beodolo yezahlulo ezingama-5,000–10,000 ukuze zithethelele ukuseta ukufa kunye nokucofa utshintsho. Iprototyping okanye i-short runs under 5,000 units, soft tooling (i-zinc cast dies okanye i-3D-printed die inserts) okanye ukusika i-laser nge-press brake bending kuneendleko eziphezulu.
Zeziphi imathiriyeli ezinokufakwa isitampu?
Phantse nayiphi na insimbi ye-ductile inokufakwa isitampu, kuquka i-low-carbon steel, insimbi engenasici, i-aluminium, ithusi, ubhedu, i-phosphor bronze, i-titanium, kunye ne-nickel alloys. Ubukhulu bezinto eziphathekayo buqala ukusuka kwi-0.1 mm ukuya kwi-6.0 mm. Imfuno ephambili yanele ngokwaneleyo - izinto ezinqabileyo ezifana nentsimbi etyhidiweyo ayigxininisi.
Kuthatha ixesha elingakanani ukwenza isitampu sife?
Ukubetha okukodwa okanye ukudluliselwa kuyafa kuthatha iiveki ezi-4-6. I-Progressive progressive isweleka kunye nezikhululo eziyi-10-20+ zithatha iiveki ezi-6-12. Iiodolo ezingxamisekileyo ngamanye amaxesha zinokucinezelwa ukuya kwiiveki ezi-3 ukuya kwezi-4 ukuze kusetyenziswe izixhobo ezilula, kodwa umgangatho kunye nobomi bokufa bunokubekwa esichengeni. Yongeza iiveki ezi-1 ukuya kwezi-2 zokuzama, ukuthatha iisampulu, kunye nokuvunywa kwenqaku lokuqala.
