Mainjiniya akamatchula magiya a mapampu a hydraulic, ma winch drive, kapena ma valve actuators othamanga kwambiri, sayamba ndi zitsulo za ufa. Ambiri amafika poyamba zitsulo zopukutira kapena zomata za CNC-mpaka kukhazikika kwa mawonekedwe, kukana kuvala, ndi mtengo wokwanira pa gawo lililonse zimayamba kusintha mawerengedwe. Ndiko kumene wodzipereka fakitale ya zitsulo zopangira ufa imasiya kukhala njira ina - ndipo imakhala chisankho chokhacho chomveka.
Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., tawona kusinthaku motsogola m'makontinenti atatu. Pampu ya North America OEM idachepetsa ma frequency osinthira magiya ndi 40% atasintha kuchoka pachitsulo chosungunuka kupita ku magiya a AMS 5387 cobalt alloy PM m'nyumba zawo zapampu za pistoni. Wogulitsa magalimoto a engineering ku Europe adachepetsa nthawi yotsogolera ndi masiku 11 - osati kufulumizitsa makina, koma pochotsa ntchito zisanu zachiwiri. Izi sizinali zopindulitsa mwaukadaulo. Amachokera ku kuwongolera kachulukidwe kachulukidwe mkati mwa ± 0.02 g/cm³, kukhala ndi kulolerana kwa phula mpaka ± 0.015 mm pamagiya a 16-module spur, ndikukwaniritsa kuuma pamwamba Ra ≤ 0.8 µm—monga-sintered.
Kulondola kwenikweni muzitsulo zaufa sikukhudza kukanikiza fumbi lachitsulo ndikuzitcha kuti zachitika. Zimayamba ndi certification yazinthu zopangira: gulu lililonse la T800 cobalt-based powder limanyamula kutsata kwathunthu kwa magawo a atomization, oxygen content (≤120 ppm), ndi kugawa tinthu (D50 = 18-22 µm). Timakana ufa kunja kwa zeneralo-ngakhale ngati ogulitsa apereka kuchotsera 15%. Chifukwa chiyani? Chifukwa kusintha kwa kachulukidwe ka 0.3% pamizu ya giya kumapangitsa kutsika kwa 22% kwa moyo wotopa wopindika ndikukweza mozungulira. Timatsimikizira izi tsiku lililonse pogwiritsa ntchito mfundo ya Archimedes ndi kusanthula kwapang'onopang'ono kwa ma cores - osati pazomaliza, koma pagawo lobiriwira, lofiirira, komanso lopindika.
Malo athu opangira amaphatikiza maluso atatu omwe masitolo ambiri a PM amawona ngati ntchito zosiyana:
- Kuwongolera mpweya ndi kuwongolera bwino kwa mame (−40 ° C mpaka -25 ° C) ndi nitrogen / hydrogen blends - yofunikira kuti ma carbide asungidwe mu ma aloyi a cobalt popanda decarburization
- Kupha ndalama ikugwiritsidwa ntchito panthawi yotulutsa, osati ngati ndondomeko yotsatila, yopereka ± 0.008 mm kuthamangitsidwa pazitsulo zamagetsi popanda kubwezeretsa
- Ntchito kutentha mankhwala ophatikizidwa mwachindunji pambuyo sintering: yankho annealing pa 1180 ° C + kuzimitsa mofulumira kwa AMS 5387, kutsatiridwa ndi kukalamba pa 845 ° C - kukwaniritsa Rockwell C 42-46 pamene kusunga gear dzino geometry.
Ena anganene kuti magiya opangidwa ndi CNC amapereka mawonekedwe apamwamba kwambiri. Zowona-kwa ma geometries osavuta. Koma kasitomala akafunsa za 22-mano, 3.5-module helical gear yokhala ndi 25 ° helix angle, spline yamkati, ndi press-fit bore - yopangidwa kuchokera ku bar yolimba ya T800 - masamu amasintha. Zokolola zimatsika mpaka 38%. Nthawi yozungulira imadutsa mphindi 92. Zida kuvala spikes pambuyo 17 magawo. Njira yathu ya PM imapereka zida zomwezo pakapangidwe kamodzi kophatikizana, ndi 91% kugwiritsa ntchito zinthu, mphindi 14 takt nthawi, ndi ziro zida kuvala pakati pa magulu. Zida zimakumana ndi AGMA Q12 ndi ISO 1328-1 Class 7-popanda kugaya.
Sitikankhira zitsulo za ufa pomwe siziyenera. Ngati ntchito yanu ikufuna kuti magiya abwerere molimba kuposa 0.02 mm pakutentha kogwira ntchito, kapena ngati kuchuluka kwa katundu wanu kumaphatikizapo kugunda kwamphamvu kopitilira 3 × torque yovotera, tikukuwuzani kutsogolo: malo opangira + omaliza akadali njira yanu yabwino kwambiri. Koma pamayendedwe apakatikati (ma PC 500-10,000 / chaka), malo ovala kwambiri (≥200 MPa kukhudzana ndi kupsinjika), kapena machitidwe omwe kulemera, phokoso, kapena zovuta za msonkhano-PM imapereka ROI yoyezera. Wopanga zida zamafuta akumwera chakum'mawa kwa Asia adalowa m'malo mwa zonyamulira zida 12-zidutswa zowotcherera ndi zida za PM imodzi. Kulemera kwatsika ndi 37%. Kugwira ntchito pamisonkhano kunatsika kuchokera ku mphindi 42 kufika ku 9. Ndipo kugwedezeka kwa matalikidwe pa 1800 rpm kunatsika ndi 63% -kuyesedwa pa malo ndi laser Doppler vibrometry.
Zomwe zimasiyanitsa wokhoza fakitale ya zitsulo zopangira ufa kuchokera ku sitolo yosindikizira zamalonda sikutha - ndi kusanthula kulephera kwenikweni. Pamene zida za kasitomala zidalephera msanga pampu ya subsea, sitinangosintha. Tinadutsa magawo omwe adalephera, kupanga mapu a porosity motsutsana ndi ma contours opsinjika, kuphatikizika kwa oxide ndi zipika zamlengalenga, ndikukonzanso mawonekedwe a mpweya wotuluka. Zotsatira: kulephera kwa zero pamiyezi 18 ndi maola 47,000 ogwirira ntchito.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imagwira ntchito kuchokera ku Qingdao-osati ngati malo opangira zolinga wamba, koma ngati chigawo cholondola pamakina omwe magiya samangosuntha mbali. Ndi zinthu zochepetsera mphamvu. Ma nangula otumizira ma torque. Kutopa-ovuta polumikizira. Timawapanga mwanjira imeneyo - kuchokera pakusankha ufa kudzera pakutsimikizira magwiridwe antchito. Malo athu ali ndi ma certification a ISO 9001:2015 ndi AS9100D, koma chofunika kwambiri ndi momwe timawagwiritsira ntchito: sitima zapamadzi zilizonse zokhala ndi malipoti athunthu, zipika za kachulukidwe, mbiri yolimba m'mbali mwa dzino ndi muzu, ndi ma micrograph azitsulo a magawo ovuta.
Tsogolo la kupanga zida zolondola kwambiri sikusankha pakati pa PM ndi makina. Ikuwaphatikiza mwanzeru - kugwiritsa ntchito PM pa geometry yapafupi ndi kukhulupirika kwamapangidwe, kenako kugwiritsa ntchito CNC yocheperako, yolunjika kumalizidwa kokha komwe kumafunikira. Njira yosakanizidwa imeneyo, kuphatikiza makina opangira makina, ndipamene cholinga chathu cha R&D chili pano. Osati kubwezeretsa ndondomeko, koma kuthetsa kusagwirizana.
