Kodi a mchenga kuponyera mtengo fakitale kulipiritsa-ndipo chifukwa chiyani zolemba zimasiyana mosiyanasiyana pakati pa ogulitsa? Tatchulapo mapulojekiti opangira mchenga okwana 1,200 kuyambira 2018. Muzochita zenizeni, mtengo wa unit umachokera ku $ 18 mpaka $ 320 pa gawo limodzi-osati chifukwa cha masewera owonetserako, koma chifukwa mitundu inayi imayang'anira mitengo: gawo la kulemera, kalasi yazinthu, kalasi ya kulekerera kwa dimensional, ndi voliyumu ya pachaka. Nyumba yachitsulo ya 5-kg ASTM A159 Kalasi 30 yachitsulo yaimvi ya pampu ya hydraulic imawononga $47 pa mayunitsi 500 / chaka. Momwemonso geometry mu AMS 5387 cobalt alloy? $ 218-yoyendetsedwa ndi mtengo wazinthu zopangira, zovuta za nkhungu, komanso chithandizo chotenthetsera pambuyo poponyedwa.
Kulemera ndi Zofunika Kuyendetsa 65% Yoyamba ya Mawu Anu
Ogula ambiri amaganiza kuti zosankha zakuthupi ndi za kukana dzimbiri kapena mphamvu. Si. Ndi za castability - ndipo castability kumafuna maola ogwira ntchito, kuchuluka kwa zinthu, ndi kuvala zida. Chitsulo chotuwira (ASTM A159) chimayenda bwino, chimachepa modzidzimutsa, ndipo sichimang'ambika nthawi zambiri. Izi zimapangitsa kuti ntchito ikhale pansi pa maola 2.1 pa tani. Cobalt-nickel alloys monga AMS 5387 amachita mosiyana: malo osungunuka kwambiri (1,350 ° C), kutsika kwamadzimadzi, komanso kukhudzidwa kwambiri ndi chinyezi cha nkhungu. Kuthira komwe kumaganiziridwa molakwika kumayambitsa 18% mkati porosity-kuchotsa mtanda wonse. Timatsata izi tsiku ndi tsiku: zokolola zathu zachitsulo chotuwira ndi 92.3%; kwa AMS 5387, ndi 74.1%. Kusiyana kumeneku kokha kumawonjezera $ 31.40 / gawo pakukonzanso ndikutayika kwazinthu.
Kulemera kumafunika—osati motsatizana, koma mochulukirachulukira. Kuponyera 12-kg kumafuna mchenga wochuluka 3.7x, 4.2x nthawi yotalikirapo, ndi 2.8x chiopsezo chosintha nkhungu pakuthira kuposa gawo la 3-kg. Injini yathu yogwiritsira ntchito imagwiritsa ntchito njira yokhotakhota yolemera-osati kutsika kwapang'onopang'ono-chifukwa pansi pa 2 kg, kuyika kumayang'anira mtengo; pamwamba pa 25 kg, nthawi ya crane ndi ndondomeko ya ng'anjo zimakhala zolepheretsa. Makasitomala omwe amakonzanso magawo kuti azikhala osachepera 18 kg amadula mtengo woponyera ndi 22-35% popanda kupereka nsembe.
Kalasi Yolekerera Ndikomwe "Zabwino Zokwanira" Zimakhala Zokwera mtengo
Izi ndi zomwe mafakitale ochepa opangira mchenga amawulula: kukumana ndi CT7 (ISO 8062) sikungopanga makina olimba. Imafuna kuwongolera kwa mchenga wobiriwira mkati mwa ± 0.8 psi, kukhazikika kwa kutentha kwa bokosi la ± 1.2 ° C, komanso nthawi yeniyeni yowunikira kupanikizika kwa metallostatic panthawi yothira. Lumphani izo? Mugunda CT9 - yovomerezeka pamabulaketi osafunikira - koma nyumba yanu ya silinda idzafunika 0.8 mm zowonjezera zoyeretsa CNC. Izi zimawonjezera $ 12.60 / gawo mu nthawi yopangira makina ndi 14% kugwiritsa ntchito zowonjezera zowonjezera.
Tawona makasitomala akutchula CT6 panyumba zoponyedwa mchenga "ngati zingachitike." Zotsatira zake? 37% mawu apamwamba, kukulitsa nthawi yotsogolera masiku 22, ndi phindu la zero. CT6 ndi ya kuponya ndalama - osati mchenga. Kwa matupi a hydraulic valve kapena maziko a pampu, CT7 imapereka umphumphu wathunthu wosindikiza ndi kuyanjanitsa kwa bolt. Ndilo malo okoma: opangidwa, owoneka bwino, komanso okwera mtengo.
Voliyumu Imasintha Chilichonse-Koma Osati Momwe Mumayembekezera
Kutsika kwamphamvu sikukutanthauza kukwera mtengo-ngati mumapewa misampha yopangira zida. Makasitomala m'modzi adayitanitsa nyumba 42 zapampu ya pistoni muchitsulo chachitsulo. Iwo anaumirira pa mtundu umodzi wa aluminiyamu. Mtengo: $2,850 chitsanzo + $142/gawo. Tinakonza patani yachitsulo yokhazikika yokhala ndi zoyikapo zosinthika zamitundu ina yamtsogolo. Mtengo: $4,100 chitsanzo + $89/gawo. Kuphwanya - ngakhale pa mayunitsi 73. Anangofunikira 42 okha. Koma dongosolo lawo lotsatira—nyumba zomwezo, makonzedwe osinthidwa a madoko—anagwiritsira ntchito njira yofanana yapansi. Zonse zosungidwa pa ntchito ziwiri: $3,210.
Voliyumu yapakatikati (mayunitsi 200–2,000/chaka) imatsegula magwiridwe antchito enieni. Pamayunitsi 500, timatsitsa mtengo wapatani, timayendetsa ng'anjo mosalekeza, ndikukonza kukonzanso mchenga mochulukira. Mtengo wa unit watsika 31% poyerekeza ndi ma prototype ambiri. Chidziwitso chofunikira: Mafakitole opangira mchenga amalipira *voliyumu yokhazikika * osati ma spikes apamwamba. Makasitomala okwana mayunitsi 300/chaka amalipira ndalama zochepa pagawo lililonse kuposa kuyitanitsa mayunitsi 1,000 kamodzi kenaka kukhala chete kwa miyezi 18.
Momwe QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. Imapereka Mtengo Wodziwikiratu Woponya Mchenga
Tinamanga malo athu ogwirizana ndi ISO mozungulira anangula atatu okwera mtengo: kuphatikiza vertical, metallurgical traceability, ndi GD&T-first engineering review. Palibe kutulutsa kwapakatikati, palibe zotenthetsera za chipani chachitatu, palibe ma aloyi osatsimikizika. Bar iliyonse ya AMS 5387 imanyamula malipoti oyesa mphero ndipo imatsimikiziridwa ndi mawonekedwe asanasungunuke. Kusakaniza kulikonse kwa mchenga kumayesedwa kuti kukhale kokwanira komanso kunyowa kwamphamvu kwa ola lililonse.
Akatswiri athu samadikirira zojambula-amayamba ndi cholinga chanu chogwira ntchito. Pampu ya ku Europe OEM itatitumizira chojambula cholemera cha GD&T cha nyumba ya T800 cobalt alloy cylinder, tidalemba zinthu zitatu zomwe zidawonjezera $19.30/gawo ndi kupindula kwa ziro: kusagwira ntchito kwa 0.025 mm flatness callout pamalo osagwirizana, zosafunikira Rz 0.8 kumalizitsa mkati mwamchenga, CMM-10000000000000000000000000000000000000000000000000000000000000000000000000 yokakamizidwa kuti amalize pakatikati. kuyendera m'malo motengera ziwerengero. Zomwe zasinthidwa: kudalirika komweko, $ 137.50 / gawo m'malo mwa $ 156.80.
Mtengo weniweni woponya mchenga supezeka mu spreadsheet. Zimatsekedwa muzosankha zasayansi, fizikiki ya nkhungu, komanso kupanga. Sankhani fakitale yomwe imayesa porosity ndi X-ray CT-osati kufufuza kokha. Izo zimatsimikizira kachulukidwe. Izi zimalepheretsa kulephera kwamunda. Izi zimapangitsa kuti mtengo wanu wonse wa umwini utsike-osati mtengo wa chinthu chamzere wokha.
Ngati mukuyesa a mchenga kuponyera mtengo fakitale, funsani mafunso atatu: Kodi mumapeza bwanji pa AMS 5387? Kodi mumatsimikizira bwanji kulimba kwa mchenga pakusintha kulikonse? Kodi mungandiwonetse deta ya mwezi watha ya Cpk pamiyeso yovuta? Mayankho amavumbula zambiri kuposa mawu aliwonse.
