Kuwotcherera Ngolo ya Rhino: Chifukwa Chake Msonkhano Wamphamvu Wamafelemu Umayamba Pamaso pa Arc Yoyamba
Mwadula chubu. Mwaumitsa zolumikizira. Mwakonzeka kugunda arc pamagalimoto anu a Rhino - ndipo ndipamene ma DIY ambiri amalephera. Osati kuchokera ku zitsulo zofooka, koma kuchokera ku kutentha kosalamulirika, kulowa mkati mosagwirizana, kapena zoikamo molakwika. Tawotchera mafelemu opitilira 12,000 amangolo athu ku Botou Haijun Metal Products Co., Ltd.—osati ngati zitsanzo, koma kuti tigwiritse ntchito m'minda yamphesa yaku North America, kupopera mbewu za zipatso ku Europe, ndi okolola mpunga ku Southeast Asia. Zomwe timawona tsiku ndi tsiku si chiphunzitso. Zimakhala zokhotakhota pambuyo podutsa kamodzi. Ma gussets osweka pansi pa 300 kg ya malipiro. Ulusi wovula m'mabowo chifukwa mbale yoyambira imasokonekera powotcherera.
Kuwotchera ngolo zamphamvu za Rhino sikungokhudza waya wa amperage kapena filler okha. Zimakhudza kutsata, kudziletsa, ndi khalidwe lakuthupi. Chitsulo chozizira—muyezo wathu wa mafelemu a Rhino—amakulitsa 12.5 µm/m·°C. Sitima yam'mbali ya 600 mm yotenthedwa mpaka 400 ° C popanda kutsekereza imakula pafupifupi 3 mm isanazizire. Kukula kumeneko sikutha. Zimatsekereza kupsinjika kotsalira. Ndipo kusweka kwa kupsinjika kumawonekera osati pakuwotcherera, koma panthawi yachitatu yonyamula katundu.
Njira Zitatu Zosakambirana Musanayambe Weld
Kudumpha chilichonse mwa izi kutembenuza ngolo yanu ya Rhino kuchoka pa chida kupita ku udindo:
Konzani mfundo zonse - osati ma weld point. Gwiritsani ntchito jigi zachitsulo zopindika zokhala ndi zoyimitsa zosinthika. Gwirani mozungulira kuzungulira kwa bulaketi iliyonse, osati msoko wowotcherera. Tidapeza kuti ngodya zopanda zingwe zimasunthika mpaka 1.8 ° pamizu yodutsa-zokwanira kusanja bwino ma wheel mounts ndi 4.2 mm kutalika kwa axle. Yang'anani motalikirapo ndi 10-mm-ndikutsimikizira masikweya kawiri. Ma tock welds ayenera kukhala olowera kwathunthu, osati ma dabs apamwamba. Mukamaliza kulumikiza, yesani ma diagonal kudutsa rectangle yayikulu. Kusiyana> 1.5 mm kumatanthauza kupotoza kwayamba kale. Pogaya ndi kubwezeretsanso. Osapitirira. Yatsani kutentha kokha ngati malo ozungulira atsika pansi pa 10°C—kapena mukugwiritsa ntchito>machubu a khoma la mamilimita atatu. Pazitsulo zozizira za 2-mm (Q235 kapena ASTM A1008), kutentha kumawonjezera chiopsezo kuposa phindu. Kuyesa kwathu kupopera mchere kunawonetsa kuti ziwalo zotenthedwa kale zidawonongeka 27% mwachangu pazala za weld chifukwa chakusintha kwakusanjikiza kwa oxide. Chifukwa chiyani "Kungowotcherera" Kumalephera Nthawi Zonse
Ena amatsutsa kuti kuwotcherera kwa MIG ndikukhululukira mokwanira mafelemu amangolo. Koma zambiri zathu za CMM zikunena nkhani ina. Pa ngolo zokwana 147 zofufuzidwa mwachisawawa za mtundu wa Rhino zomangidwa ndi anthu okonda masewera olimbitsa thupi, 68% adawonetsa kupatuka kwamakona> ± 2.3 ° pamakona apakona. Ndi 11% yokha yomwe idapambana kuyesa kogwira ntchito ndikulipira kwathunthu. Chifukwa chake? Kusagwirizana kwa liwiro la kuyenda. Kutsika kwa 15% pa liwiro laulendo kumawonjezera kutentha ndi 34%. Zomwe zimasungunula zitsulo zambiri, zimakulitsa malo omwe amakhudzidwa ndi kutentha (HAZ), ndikufewetsa kapangidwe ka tirigu moyandikana ndi weld. Zotsatira: ming'alu ya kutopa imayamba pamalire a HAZ pambuyo pa maola ogwirira ntchito 1,200-1,800-osati zaka zambiri.
Timagwiritsa ntchito pulsed MIG popanga mafelemu onse amtundu wa Rhino. Kuthamanga kwafupipafupi kumakhala kokhazikika pa 120 Hz. Pamwamba pakali pano ndi 185 A. Kumbuyoku kumatsikira ku 42 A. Izi zimapereka kusintha kwa madontho, kumachepetsa spatter ndi 70%, ndikusunga m'lifupi mwa HAZ pansi pa 1.1 mm-ngakhale pamachubu a 2.5-mm. Kwa owotcherera a DIY opanda mphamvu yakugunda? Gwiritsani ntchito kusuntha kwachidule, sungani mtunda wosachepera 12 mm, ndikusuntha 35-40 cm / min. Chilichonse chocheperako chimayitanira kuwotcha. Chilichonse chofulumira chimayitanitsa kusowa kwa fusion.
Mtengo Weniweni Wowotcherera Wofooka wa Chipembere
Sikuti kulephera kwamapangidwe. Ma welds ofooka amayendetsa ndalama zobisika:
Kuyambiranso ntchito: Kugaya gusset yosweka kumatenga mphindi 22. Kuwotchereranso molondola-ndi kutentha koyenera kwa interpass-kuwonjezera wina 18. Ndiwo mphindi 40 zomwe zimatayika pamgwirizano. Pa chimango chathunthu? Kupitilira maola atatu. Zinyalala zakuthupi: Sinja yam'mbali imodzi yomwe yalephera imatanthauza kuthyola njanji zonse ziwiri - chifukwa kufananiza mawonekedwe a tirigu ndi kumaliza pambuyo pa weld sikungatheke popanda mphero. Nthawi yopuma: Ngolo yomwe imalephera kukolola nthawi yokolola imawononga $190 / ola chifukwa cha ntchito yotayika komanso nthawi yopanda ntchito. Makasitomala athu amafotokoza nthawi yanthawi yayitali pazolephera zokhudzana ndi weld: masiku 11.3. Botou Haijun amapewa izi pokhazikitsa malire a kutentha kwa ≤150°C. Timawunika kuwotcherera kulikonse ndi infrared thermography - osati kungoyerekeza. Ngati kutentha kukukwera pamwamba, timapuma. Tikuyembekezera. Timazizira. Palibe kuchotserapo.
Zomwe Zimagwira Ntchito-ndi Zomwe Sizichita-pa Mafelemu a Ngolo ya Rhino
Tinayesa machitidwe asanu omwe amagwiritsidwa ntchito pa zitsanzo 420 zowotcherera. Izi ndi zomwe zidachitika:
Gusset mawonekedwe. Miyendo ya katatu yokhala ndi miyendo 45 ° idapambana ya amakona anayi ndi 41% pakuyesa kulimba kwa torsional. Makona a radius pamalangizo a gusset adachepetsa kupsinjika ndi 63% (kuyezedwa ndi ma geji azovuta). Mayendedwe a weld amawongolera kusokonekera. Kuwotchera kuchokera pakati panja panjanji zazitali kumadula kugwada ndi 82% motsutsana ndi njira zoyambira mpaka kumapeto. Kutsata: pakati → ¼ mfundo → ¾ mfundo → mapeto. Kuchepetsa kupsinjika kwapambuyo pa weld sikuli kosankha pazowonjezera zolipira> 250 kg. Timayika mafelemu pa 580 ° C kwa mphindi 45 mu ng'anjo zoyendetsedwa. Kuzizira kwa mpweya pambuyo pake kumachepetsa 94% ya kupsinjika kotsalira kotsalira. Kudumpha sitepe iyi kunakulitsa chiwopsezo cha kuyambitsa ming'alu ndi 5.7 × pakuyezetsa moyo kwachangu. Cholemba chomaliza: kuwotcherera ngolo ya Rhino sikutanthauza mphamvu zankhanza. Ndi za geometry yoloseredwa, yobwerezabwereza. 13Ndipo zowotchera zonse ziphatikizepo khamulo, osaphatikizira zidutswa ziwiri; Malingaliro amenewo amalekanitsa ngolo zomwe zimatha nyengo zisanu ndi zomwe zidachotsedwa pambuyo pa imodzi.
Ngati chimango cha ngolo yanu ya Rhino ikufunika kuwotcherera mwatsatanetsatane komwe kumapulumuka katundu weniweni, Botou Haijun Metal Products Co., Ltd. imapereka upangiri waukadaulo-womangidwa pazitsulo zoziziritsa kuzizira, zovomerezeka ndi CMM ndi kuyezetsa kovutirapo, komanso mothandizidwa ndi kuwongolera kogwirizana ndi ISO. Sitigulitsa magawo. Timapereka chitsimikizo cha dimensional.
