Pamene mainjiniya afotokoza mwambo wachitsulo kuponyera kwa ma hydraulic manifolds, nyumba zapampu, kapena ma winch system shafts, sikuti amangoyitanitsa zitsulo-amatsekera mokhazikika, kukhazikika kwa microstructural, komanso kukana kutopa kwanthawi yayitali pansi pa zovuta zenizeni. Tawona mapulojekiti ambiri akuyimitsidwa chifukwa zoponyera pashelufu zidasokonekera pakukonza komaliza, kapena kulephera kuyesa kwa hydrostatic chifukwa cha kuchepa kwamphamvu kosazindikirika. Ichi ndichifukwa chake zigawo zamafakitale zolondola zimafuna zambiri kuposa mphamvu zoyambira - zimafunikira kuwongolera kwazitsulo zophatikizika, njira zolumikizirana zolimba, komanso kusalekerera kusinthasintha kwa batch-to-batch.
Chifukwa Chake "Mwambo" Kuponya Chitsulo Sikungokhudza Mawonekedwe - Ndi Za Kachitidwe Kachitidwe
Iron si chinthu chimodzi. Iron Gray (ASTM A48 Class 30B), ductile iron (ASTM A), ndi austempered ductile iron (ADI) amachita mosiyana kwambiri pansi pa matenthedwe apanjinga, kuvala abrasive, kapena cyclic loading. Nyumba ya silinda ya pampu ya pistoni iyenera kukana kusweka pang'ono pa bar 350 ndikusunga mozungulira mkati mwa ± 0.015 mm pambuyo pa kutentha. Winch center shaft roller imafuna kulimba kwa pamwamba ≥55 HRC *ndi* kulimba kwenikweni kwa mphamvu ya 15 ft·lb—osati mitundu iwiri yosiyana, koma chofunikira chimodzi chodalirana.
Nthawi zambiri timakumana ndi zojambula zomwe zimatchula "chitsulo choponyedwa" popanda giredi, kulimba kwamphamvu, kapena graphite morphology control. Kusamvetsetseka kumeneku kumapangitsa kukonzanso kokwera mtengo: tataya magulu atatu a ma valve opanikizika chifukwa ma microstructure opangidwa ndi as-cast analibe kugawa kwamtundu wofunikira wa mtundu A-kutsimikiziridwa kokha pambuyo powononga zitsulo. Kuponyera chitsulo mwamakonda kumayamba ndi kusankha kwazinthu kumangirizidwa kunjira zonyamula katundu, osati manambala amakasitomala.
Njira yathu imayambira pachipata: zopangira zovomerezeka zochokera kwa ogulitsa owerengetsera, kuwunikira kwathunthu kutentha kudzera pamakhodi opaka laser, ndi kusanthula kowoneratu kwa zinthu zotsalira monga Ti, Pb, kapena Sb - zomwe zimadziwika kuti zimadetsa machinability ndi nodularity mu chitsulo cha ductile. Palibe zongoganizira. Palibe njira zazifupi.
Kumene Kuponyera Mchenga Kumakumana ndi Zowona za CNC-Ndi Chifukwa Chake Kuphatikizika Kwamagawo Kumafunika
Zolephera zambiri m'zigawo zachitsulo zothamanga kwambiri sizichitika panthawi yoponyera-koma pamawonekedwe apakati pa kuponyera ndi makina. Nyumba yokhala ndi mchenga imatha kukumana ndi kulekerera kwapataniyo, komabe imasokonekera mosayembekezereka panthawi yochepetsera kupsinjika kapena kukanikizidwa pamilling yamitundu yambiri. Tidayeza uta wa 0.12 mm m'mabowo a silinda aatali a 400-mm titapanga movutikira, zokwanira kuti tichotse gawo la $2,800.
Ndicho chifukwa chake malo athu amachitira kuponyera, chithandizo cha kutentha, makina a CNC, ndi kuyendera pansi pa denga limodzi. Tima makina obowola ofunikira ndi osindikiza * tisanapeze * mpumulo womaliza wa kupsinjika-pogwiritsa ntchito macheke a CMM okhazikika kuti apange mapu osokoneza ma vector. Kenako timagwiritsa ntchito zolipirira pomaliza. Kachitidwe ka haibriditi kameneka kamachepetsa mitengo yotsalira ndi 63% motsutsana ndi mavenda otsatizana.
Zotheka zazikulu ndi izi:
- Kuponya mchenga kokhala ndi kuwombera kokhazikika pamakina ovuta amkati (monga ma hydraulic manifolds amitundu yambiri)
- Kuwongolera kozizira kozizira kuti muchepetse kupsinjika kotsalira m'magawo okhuthala
- Makina a 5-axis CNC osokonekera - monga mano a zida pa maziko a pampu - ndi chipukuta misozi chanthawi yeniyeni
- Kutsimikizira kukhulupirika kwapamwamba pogwiritsa ntchito interferometry yowala yoyera pankhope zosindikiza
Palibe wogulitsa wakunja yemwe angatsanzire izi. Dimensional drift imagwidwa isanakhale zidutswa.
Kutsimikizika Kwapadziko Lonse: Zomwe Makasitomala Amayesa
Makasitomala samasayina pa "kufanana ndi kujambula." Iwo amatsimikizira ntchito. Kuyika kwa nozzle ya cobalt kumatha kudutsa cheke chilichonse cha NDT - ndikuwonongabe 40% mwachangu kuposa momwe zimakhalira mumayendedwe othamanga kwambiri. Kotero ife timayesa kupitirira miyezo.
Pa dongosolo lililonse lopangira chitsulo, timachita:
- Akupanga kuyezetsa pa ASTM E186 kwa discontinuities mkati m'magawo ovuta
- Kulimba kwa mapu kudutsa magawo odutsa-osati kungowerengera pamwamba-kutsimikizira kusinthika kofanana mu magawo a ADI
- Kuyesa kukakamiza kogwira ntchito pa 1.5 × kukakamiza kugwira ntchito kwa mphindi 30, ndikuwunika kwa digito kutsika (≤0.05 cc/min kuvomerezedwa)
- Kutsimikizika komaliza kwa GD&T pogwiritsa ntchito Zeiss Contura G2 RDS CMM yokhala ndi masitayilo a ceramic
OEM imodzi yaku Europe idakana nyumba zisanu ndi imodzi za ma silinda chifukwa kutayikira kwawo kunakwera pamwamba pa 0.12 cc/mphindi pa 40°C—kutengera kuchuluka kwa ma graphite nodule m'malo obowoleredwa. Tinasintha kachitidwe ka katemera, kuwonjezera kujambula kwa kutentha panthawi yothira, ndikupereka chiphaso choyamba 合格 pa liwiro lachisanu ndi chiwiri. Umenewo si mwayi. Ndi chidziwitso chaukadaulo chomwe adapeza zaka 17 zakuponya chitsulo pamapampu amafuta ndi ma hydraulics oyenda.
Kusankha Mnzanu Wabwino wa Mission-Critical Iron Castings
Funsani omwe akukugulirani: Kodi angatsatire tani iliyonse yachitsulo kubwerera ku chipika chake chosungunuka? Kodi ali ndi ziphaso za ISO 9001:2015 *ndi* AS9100D—kapena chimodzi chokha? Kodi awunikanso ma callout anu a GD&T ndikuwonetsa mikangano yomwe ingachitike pakupanga makina *zisadayambe* zida?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. amapereka mwambo wachitsulo kuponyera mayankho omwe zitsulo, geometry, ndi fiziki yakugwiritsa ntchito zimakumana. Sitigulitsa ma castings. Timapereka magwiridwe antchito otsimikizika - osasunthika, osasunthika mwazitsulo, komanso zotsimikizika. Malo athu opangira amakhala ocheperako, koma mbiri yathu yabwino imakhala yozama: ma cert athunthu, malipoti a CMM, ndi zolemba zoyeserera zosungidwa zaka 15.
Kuyang'ana m'tsogolo, tikukulitsa luso lopangira chitsulo chachitsulo chochepera 2 kg - kutsata nyumba zopangira mlengalenga ndi mafelemu a zida zamankhwala komwe kusiyanasiyana kwachitsulo ndi kuuma ndikofunikira kwambiri. Mfundo yayikulu sinasinthidwe: chitsulo chosungunuka si chitsulo cholowa. Ndi gawo ladongosolo lopangidwa ndendende-pamene limachitidwa motero.
