Mainjiniya akamatchula zitsulo zopangira ma hydraulic manifolds, mapampu, kapena ma roller a winch shaft, sikuti amangogula zitsulo - akugula kukhazikika kwa 300-bar pressure, microstructural consistency kudutsa 500-part batches, ndi zero kulolerana kwa porosity m'madera onyamula katundu. Chifukwa chake "mwambo chitsulo kuponyera fakitale” si gulu la mavenda-ndilo gawo lantchito.
Tawona ma projekiti ambiri akuchedwetsedwa ndi oyambitsa omwe amayesa kuponya chitsulo ngati ntchito yazachuma: kuchuluka kwa ma graphite nodule kunyalanyazidwa, malipiro ochepera omwe amaganiziridwa kuchokera ku zojambula zakale, ndondomeko zochizira kutentha zimagwiritsidwa ntchito nthawi zonse. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Kupanga chitsulo kulikonse kumayamba ndi zitsulo - osati kungodzaza nkhungu. Malo athu ogwirizana ndi ISO ku Qingdao amayendetsa njira zoponyera mchenga zofananira ndi ASTM A48 Class 35, A536 ductile iron, ndi zosakanikirana zamtundu wa ferritic-pearlitic — chilichonse chimasankhidwa kuti chifanane ndi mbiri yakupsinjika, osati ma chart olimba.
Zofuna zenizeni padziko lapansi zimapanga machitidwe athu. Panyumba za silinda ya pampu ya pistoni, timawongolera kuziziritsa mkati mwa ± 2 ° C kudutsa nkhungu kuti tipewe kupotoza polumikizana ndi bore. Kwa injini zamagalimoto opangira ma winch center shaft rollers, timatsimikizira graphite morphology kudzera pa SEM tisanapange makina-chifukwa kugawa kwa flake kumakhudza mwachindunji moyo wa kutopa pazigawo za 12,000-cycle. Ndipo makasitomala akatumiza ma callouts a GD&T ngati ⌀0.015 mm kulolerana kwa malo pa 8 × Ø22 mm bores okwera, sitimangoyesa—timayerekezera kukulitsa kwamafuta panthawi yopanga makina, kenaka timasintha zida zosinthira munthawi yeniyeni pogwiritsa ntchito ma probe a Renishaw QC20-W. Umu ndi momwe timakhalira ndi malo enieni mkati mwa 0.008 mm pazopanga zambiri.
Kuphatikiza koyima kumapangitsa izi kukhala zotheka-ndi zofunika. Kuponyera, CNC Machining, ndi kumaliza pamwamba kumachitika pansi pa denga limodzi. Palibe ma handoffs omwe amatanthauza kuti palibe kusuntha kwapakatikati pakati pa kuponyera ndikumaliza komaliza. Timayika makina molunjika pamalo oponyedwa momwe zingatheke, ndikuchotsa zolakwika zokonzanso. Kuchiza kutentha kumatsatira kuponya popanda kuchedwa kusuntha kwa zinthu-kofunikira kwambiri kuti mukwaniritse kulimba kwa Brinell (220-260 HBW) pazigawo zazikuluzikulu. Ndipo chifukwa timapeza zopangira zovomerezeka - zomwe zingatsatidwe ndi malipoti oyesa mphero - timadziwa kuchuluka kwa sulfure pagulu lililonse tisanathire. Sulfure pamwamba pa 0.025%? Wakanidwa. Osati chifukwa zimaphwanya spec-koma chifukwa zimayika pachiwopsezo cha micro-shrinkage pakati pa magawo owonda ndi okhuthala.
Chosiyanitsa chathu champhamvu kwambiri si zida-ndikugwiritsa ntchito bwino. Pamene wogwiritsa ntchito mafuta aku North America amafunikira zigawo za pampu za AMS 5387 cobalt alloy zomwe zidasinthidwa kukhala chitsulo cha ductile kuti tipeze zosungira zotsika mtengo, sitinangosinthana zinthu. Tidatengera njinga zamatenthedwe mu ANSYS, tidasintha ma nodularization agents kuti tisunge 18% elongation pa -20 ° C, ndikutsimikizira kukana kwa ma API RP 14E kukokoloka kwa ma curve. Zotsatira: 40% mtengo wotsika wagawo, kulephera kwa zero pamiyezi 18. Ndiko kusiyana pakati pa chitsulo choponyera chitsulo ndi khalidwe lachitsulo chaumisiri.
Ngati mukuyesa a mwambo chitsulo kuponyera fakitale, funsani mafunso atatu: Kodi angakuwonetseni lipoti laposachedwa la CMM pagawo lomwe lili ndi ≥5 ma data ovuta? Kodi amasunga kutsata kwazinthu zonse - kuphatikiza zipika za ladle chemistry - pa dongosolo lililonse? Ndipo kodi gulu lawo la mainjiniya lidzapereka mikangano ya GD&T *isanatchule*—osati pambuyo pounika nkhani yoyamba? QINGDAO QIANGSENYUAN TECHNOLOGY imayankha kuti inde—nthawi iliyonse. Chifukwa kudalirika sikuperekedwa mumtsuko wotumizira. Zimapangidwa mu kutsanulira kulikonse, kutentha kulikonse, micrometer iliyonse ya makina oyendetsedwa.
