Ukuwelda ngaphandle kwe-a itafile yejig ye-welding kufana nokudibanisa ifanitshala ene-screwdriver yentloko kaPhillips kuphela - kunokwenzeka, kodwa icotha, ayihambelani, kwaye ithande ukuphinda isebenze kwakhona. Sizibonele mathupha: umthengisi woomatshini bezolimo we-Tier-1 eWisconsin ulahle i-12% yee-bracket subassemblies zayo kulo nyaka uphelileyo ngenxa yokuba ukugqwetheka kwe-weld kudlule ku-± 0.5 mm ukunyamezelana kwisibiyeli esilula se-L. Oyena nobangela? Akukho ukulungiswa okuzinikeleyo-ziintambo nje zemagnethi kunye ne-intuition yomsebenzisi.
Kutheni “Ukulunga ngokwaneleyo” Ukulungisa kusilela phantsi koxinzelelo lokwenyani lweMveliso
Uninzi lweevenkile ziphatha iitafile zejig njengezixhobo ozikhethelayo - de i-weld misalignment ibangele imiba esezantsi yokufaneleka kwiiseli zokupeyinta iirobhothi okanye ukunyuswa kwe-hydraulic manifold. Yinyani itafile yejig ye-welding ayisiyonto nje ipleyiti yentsimbi enemingxuma. Sisiseko esilawulwa ngokulungelelanisiweyo esivala inxalenye yejometri * phambi kokuba i-arc ibethe.
Sivavanye iindlela ezintlanu eziqhelekileyo kwiifreyimu zentsimbi eziqengqelekayo ezi-3-mm ezifanayo:
Izibophelelo zemagneti zizodwa → i-avareji ye-positional drift: 1.8 mm emva kokudlula kwe-weld ezi-3 Izixhobo ezilungiselelwe oko-nye (intsimbi edityanisiweyo) → ixesha lokumisela: imizuzu engama-22 inxalenye nganye; ukuphinda-phinda: ± 0.7 mm Iitheyibhile zemodyuli yomngxuma-pattern (100 mm igridi) → ukwanda kwe-thermal kubangele i-0.4 mm shift kwi-85°C i-interpass temp ISO-standard T-slot tables kunye nezikhonkwane zendawo ezichanekileyo → ukuphindaphindwa okugcinwe ku-±0.15 mm kwimijikelo engama-50 Iitafile ze-Hybrid jig ezinemigangatho edibeneyo ye-datum kunye neempawu zendlwane ezinomatshini we-CNC → ±0.08 mm ngaphezu kweeyunithi ezingama-200, ukungasebenzi kwakhona kweqanda Umahluko awukho ithiyori. Ziindleko ezilahliweyo, umsebenzi wokuhlola, kunye nexesha lokunciphisa umgca. Omnye umthengi unqumle ixesha lokulungiswa kwe-post-weld ngama-68% emva kokutshintsha ukusuka kwi-generic clamping ukuya kwinkqubo yetafile ye-jig eyakhelwe injongo.
Iimpawu ezine ezingaxoxisiyo Itafile yakho ye-Welding Jig kufuneka ibe nayo
Ayizizo zonke iitafile zejig ezihambisa iiweld ezifanayo. Ngokusekwe kwiminyaka eli-17 yokwakha amacandelo esinyithi achanekileyo kubathengi bezithuthi kunye nezixhobo zokwakha, nantsi eyona nto ibalulekileyo - hayi iincwadana zentengiso:
Ukunyamezela kwe-flatness ≤ 0.05 mm / m - Ilinganiswe ngepleyiti yegranite esemgangathweni, hayi i-straightedge. Nakuphi na ukutenxa kukhulisa impazamo ye-angular kwii-welds ezinamanqaku amaninzi. Imiphezulu eqinileyo, ebekwe phantsi - Hayi nje intsimbi egayiweyo. Sisebenzisa i-induction-hardened 45 # intsimbi kunye ne-58-62 HRC yobulukhuni bomhlaba. Iitafile ezingaqiniwanga zinxiba ngaphantsi kweenyanga ezi-3 zokusetyenziswa kwemihla ngemihla, ziphulukana nokuphinda ziphindeke ngokukhawuleza. I-anchoring yemodyuli ene-≤ 0.02 mm yokuphinda ukufakwa -Imigangatho ye-16-mm T-slots isebenza, kodwa i-ISO 841-ehambelana ne-dovetail okanye iinkqubo zokutshixa ngokukhawuleza zinciphisa ukuseta ukuhluka nge-40% kwiindawo ezixubeneyo eziphezulu. Ulawulo lobunzima bobushushu - Iipleyiti zesiseko ezityebileyo (≥ 80 mm) ezineembambo zangaphakathi zichitha ubushushu ngokukhawuleza. Iitheyibhile ezibhityileyo zijika phantsi kokudlula okuphindaphindiweyo kwe-GMAW, ukuhambisa inxalenye yendawo phakathi komsebenzi. Ungayihoyi nayiphi na kwezi, kwaye i-jig yakho "echanekileyo" iba yi-bottleneck ehambelanayo.
Xa iitheyibhile zeJig zesiko zigqithisa ngaphandle kwe-Shelf-Kwaye xa zingenzi
Ezinye iinjineli zicinga ukuba iitafile ze-jig zihlala ziphezulu. Kodwa sizihambisile zombini - kwaye idatha ibonisa ngenye indlela.
Ngomthamo ophantsi, imisebenzi eguquguqukayo ephezulu (umzekelo, iprototype yezixhobo zokusetyenziswa kwezolimo), iimodyuli zejig tables ezineendlwana ezitshintshayo kunye neendawo ezilungelelanisiweyo zinqumle ixesha lokuseta ngama-75% ngokuchasene nezixhobo zesiko elidityanisiweyo. Abathengi babika i-ROI phantsi kweeveki ze-4.
Kodwa kumthamo ophezulu, iindawo ezinyamezelayo eziqinileyo - njengezibiyeli zensimbi ezingenasici kwi-gantries ye-imaging yezonyango - iitafile ze-jig ezenzelwe ngokupheleleyo kunye neziteshi zokupholisa ezidibeneyo kunye ne-laser-tracked datum points zihambisa iinzuzo ezinokulinganiswa: i-92% yokungaphumeleli okuncinci, i-30% ephantsi kwe-weld spatter rate (ngenxa ye-stable part-to-electrode-firstspection-100% iingxelo.
Into ethatha isigqibo ayilohlahlo lwabiwo-mali. Yiyo inxalenye entsonkothileyo + umthamo wonyaka + iimfuno zokupakisha ukunyamezela. Ukuba i-GD&T yakho ifuna unyamezelo lwesikhundla olungqongqo kune-±0.1 mm, iinkqubo zeemodyuli azifane zanele.
Indlela kaBotou Haijun: Ubunjineli boLungiso kwiCandelo, hayi ngakulo
Kwi-Botou Haijun Metal Products Co., Ltd., asiyiphathi iitafile zejig njengezixhobo ezizimeleyo. Siyila njengezandiso zenxalenye ngokwayo.
Xa i-OEM yaseYurophu idinga ulungelelwaniso lwe-weld olungaguqukiyo kwizivalo zebhetri ye-aluminium yeeforklift zombane, siye sasebenza ngobunjineli bokufumana amanqaku ngokuthe ngqo kwindawo engenanto egximfiziweyo - songeza iipads ezincinci, eziqinileyo kunye neencam zereferensi ngexesha lokugqibela lokugoba. Oko kwaphelisa amacandelo ahlukeneyo, kucuthwe ixesha lokuseta lilonke ngama-40%, kwaye itshixelwe indawo yomthungo we-weld ngaphakathi kwe-±0.05 mm - nokuba amaqondo obushushu evenkile aguquguquka nge-15°C yonke imihla.
Oku kudityaniswa kuyasebenza kuba indawo yethu ilawula isitampu, ukugoba, ukuwelda, kunye ne-metrology phantsi kophahla olunye. Siqinisekisa yonke uyilo lwetafile yejig sisebenzisa iimephu ze-CMM-scanned weld distortion - hayi nje iitshekhi ezimileyo. Zonke iinqanawa ezilungiselelweyo ezinengxelo yolungelelwaniso eqinisekisiweyo kunye nejiko le-thermal drift ngokusekwe kwidatha yomjikelo wemveliso.
Ukuba uvavanya a itafile yejig ye-welding, buza umthengisi wakho: Ngaba bayayivavanya indlela yokusebenza phantsi komthwalo wokwenyani oshushu? Ngaba bangakwazi ukulandelela ukuphindaphinda babuyele kumanani ezinto ezikrwada? Ngaba bayahlengahlengisa iindawo zephini ngokusekwe kwidatha ye-springback evela kwi-alloy yakho ethile kunye nobukhulu?
Yiloo ndlela i-welds ehambelanayo iqala ngayo - ixesha elide ngaphambi kokuba i-arc yokuqala ivuthe.
