Rhino Cart Welding: Nei Yakasimba Frame Gungano Inotanga Pamberi peArc Yekutanga
Iwe wakacheka tubing. Iwe wakaoma-wakaisa majoini. Iwe wakagadzirira kurova arc pane yako Rhino ngoro furemu-uye ndipo chaipo apo akawanda DIY anovaka anokundikana. Kwete kubva kusimbi isina simba, asi kubva pakupisa kusingadzoreki, kupinda kusingawirirani, kana zvigadziriso zvisina kurongeka. Takasoneredza mafuremu engoro dzinopfuura zviuru gumi nembiri kuBotou Haijun Metal Products Co., Ltd.-kwete semaprototypes, asi kuti ashandiswe mumunda muminda yemizambiringa yekuNorth America, masprayers eminda yemichero kuEurope, nevacheri vemupunga vekuSoutheast Asia. Zvatinoona zuva nezuva hazvisi dzidziso. Yakamonyoroka mitezo mushure mekupfuura kamwe chete. Yakatsemuka gussets pasi pe300 kg yemubhadharo. Mashinda anobvisa mumakomba anokwirisa nekuti base plate yakanganisa panguva yewelding.
Yakasimba Rhino ngoro welding haisi yeamperage kana yekuzadza waya chete. Izvo ndezvekutevedzana, kuzvidzora, uye maitiro enyama. Simbi inotonhorwa — muyero wedu wemafuremu eRhino — unowedzera 12.5 µm/m·°C. Njanji yeparutivi 600 mm inopisa kusvika 400 ° C isina kusungirirwa inokura inoda kusvika 3 mm isati yatonhodza. Kukura ikoko hakuperi. Inovhara mukusarira kunetseka. Uye kutsemuka kwekushushikana kunoonekwa kwete panguva yewelding-asi panguva yechitatu yekutenderera kutenderera.
Matanho Matatu Asingakurukurirwe Usati Wasvina
Kusvetuka chero yeiyi inoshandura ngoro yako yeRhino kubva kune chishandiso kuenda kune mutoro:
Rongedza majoini ese-kwete chete weld points. Shandisa mabolted angle-iron jigs ane zvinogadziriswa zvinomira. Batanidza perimeter yese yebracket yega yega, kwete chete weld seam. Takaona kuti makona asina kuvharwa anochinja kusvika 1.8 ° panguva yekupfuura kwemidzi-yakakwana kusaisa mavhiri evhiri ne 4.2 mm pakureba kweaxle. Pre-tack ne 10-mm intervalness- uye simbisa squareness kaviri. Tack welds dzinofanirwa kunge dzakazara-kupinda, kwete pamusoro dabs. Wapedza kukwenya, pima diagonals kuyambuka rectangle huru. Musiyano> 1.5 mm zvinoreva kukanganisa kwave kutovaka. Gaya uye dzokorora. Usaenderere mberi. Preheat chete kana ambient yadzika pasi pe10°C—kana kuti uri kushandisa >3-mm kumadziro tubing. Kune yakajairwa 2-mm inotonhora-yakakungurutswa simbi (Q235 kana ASTM A1008), preheat inowedzera njodzi kupfuura kubatsirwa. Yedu yekupfapfaidza munyu yekuyedza yakaratidza majoini akafanopisa akaora 27% nekukurumidza pazvigunwe zveweld nekuda kwekugadziriswa kwe oxide layer. Sei "Kungoishongedza" Inokundikana Nguva Yese
Vamwe vanopokana kuti MIG welding inoregerera zvakaringana kumafuremu engoro. Asi yedu CMM data inotaura imwe nyaya. Pa147 yakaongororwa zvisina tsarukano maRhino-style ngoro dzakavakwa nevanofarira, 68% yakaratidza kutsauka kwekona> ± 2.3 ° pamajoini emakona. Chete 11% yakapfuura bvunzo inoshanda ine mubhadharo wakazara. Chikonzero chikuru? Kufamba nekukurumidza kusaenderana. Kudonha kwe15% mukumhanya kwekufamba kunowedzera kupisa kupinza ne34%. Iyo inonyungudutsa simbi yakawanda, inowedzera nzvimbo inobatwa nekupisa (HAZ), uye inopfavisa chimiro chezviyo chiri padhuze neweld. Mhedzisiro: kuneta kutsemuka kunotanga paHAZ miganhu mushure me1,200-1,800 maawa ekushanda-kwete makore gare gare.
Isu tinoshandisa pulsed MIG kune ese ekugadzira Rhino ngoro mafuremu. Pulse frequency inogara yakagadziriswa pa120 Hz. Peak current inobata 185 A. Background current inodonha kusvika ku42 A. Izvi zvinoburitsa madonhwe chaiwo, zvinoderedza spatter ne70%, uye zvinochengeta Hupamhi hweHAZ huri pasi pe1.1 mm—kunyangwe pa2.5-mm tubing. Kune DIY welders pasina pulse kugona? Shandisa pfupi-circuit kutamisa, ramba wakanamatira kunze kwe12 mm, uye famba pa 35-40 cm / min. Chinhu chipi nechipi chinononoka chinokoka kupisa-kuburikidza. Chero chipi zvacho chinokurumidza chinokoka kushomeka-kwe-fusion.
Mutengo Wechokwadi weWeak Rhino Cart Welding
Haisi kungokundikana kwemaitiro. Weak welds anotyaira mitengo yakavanzika:
Basa rekushanda zvakare: Kukuya gusset yakatsemuka kunotora maminitsi makumi maviri nemaviri. Kuibatanidza zvakare nemazvo-nekudzora tembiricha yakakodzera-inowedzera imwe 18. Ndiyo maminetsi makumi mana akarasika pajoini. Pafuremu yakazara? Kupfuura maawa matatu. Kuraswa kwezvinhu: Imwe yakundikana njanji yedivi zvinoreva kukwenya njanji dzese-nekuti kuenzanisa kutariswa kwezviyo uye kupedzisa kwepamusoro post-weld hazvigoneke pasina giyo-level annealing. Munda downtime: Ngoro inokundikana pakati pekukohwa inodhura $190/awa mukushanda kwakarasika uye nenguva isina basa. Vatengi vedu vanoshuma avhareji yekugadzirisa nguva yekutadza-kwakabatana ne weld: 11.3 mazuva. Botou Haijun inodzivirira izvi nekumanikidza miganhu yematembiricha ye ≤150°C. Isu tinotarisisa weld yega yega ne infrared thermography-kwete kufungidzira. Kana tembiricha yakwira pamusoro pechikumbaridzo, tinombomira. Tinomirira. Tinotonhodza. Hapana kunze.
Chii Chinoshanda-Uye Chisingaite-paRhino Cart Frames
Takaedza maitiro mashanu akajairwa mukati me420 weld samples. Hezvino izvo zvakamira:
Gusset chimiro chakakosha. Triangular gussets ane 45 ° makumbo akakunda rectangular ne 41% mu torsional rigidity bvunzo. Radhiyasi makona pamazano egusset akadzikisa kushushikana kwekushushikana ne63% (kuyerwa kuburikidza nemajeji ekuyeresa). Weld nzira inodzora kukanganisa. Welding kubva pakati nekunze panjanji refu dzakacheka kukotama ne82% maringe nekutanga-kusvika-kumagumo. Kutevedzana: pakati → ¼ poindi → ¾ poindi → magumo. Post-weld stress relief haisi sarudzo yekubhadhara mitoro> 250 kg. Isu tinobata mafuremu pa580 ° C kwemaminetsi makumi mana nemashanu mumavira anodzorwa. Kutonhodza kwemhepo mushure kunobvisa 94% yekusarira kunetseka. Kusvetuka danho iri kwakawedzera mwero wekutanga kutsemuka ne5.7× mukukasira kuyedza hupenyu. Imwe yekupedzisira chinyorwa: Rhino ngoro welding haisi yesimba rehutsinye. Zviri zvekufungidzira, zvinodzokororwa geometry. Soka inovhenganiswa yose inofanira kubatanidzwa paungano, kwete kungobatanidza zvidimbu zviviri. Mafungiro iwayo anopatsanura ngoro dzinogara mwaka mishanu kubva kune dzakaraswa mushure meimwe.
Kana ngoro yako yeRhino furemu ichida kukwenenzverwa simbi inopona mitoro yepasirese, Botou Haijun Metal Products Co., Ltd. inopa huinjiniya-giredhi yekugadzira-yakavakirwa painotonhora-yakakungurutswa simbi, yakasimbiswa neCMM uye tensile kuyedzwa, uye inotsigirwa neISO-yakarongedzerwa process control. Hatitengesi zvikamu. Isu tinoburitsa dimensional chokwadi.
