Welding zvigadziriso zvinobata zvikamu munzvimbo chaiyo-hapana kufungidzira, hapana rework. Kana kushivirira kuchidzika kusvika ku ± 0.1 mm uye nguva dzekutenderera dzinoda kudzokorora mukati me500+ mayunitsi, akajairwa jigs anokundikana. Ndiko uko 3D welding chigadziriso masisitimu anopindira-kwete sekuwedzera, asi seakagadziridzwa mawedzero echinangwa chewelder.
Nei "3D" ichichinja izvo Fixtures Inogona Kuita
Iyo 3D welding fixture haina kutsanangurwa nehuwandu hwayo hwematemo. Zvinotsanangurwa nemagadzirisiro aanoita zvimhingamipinyi zvepasirese: makomisheni emakona mumabhuraketi echassis, mafurange akaiswa pa hydraulic manifolds, kana magungano emhando dzakawanda apo kuwedzera kwemafuta kunosiyana pakati pealuminium nesimbi isina tsvina. Takaona vatengi vachirasa 12% yemabhechi ekutanga nekuti zvigadziriso zvenhaka zvaisakwanisa kuchengetedza perpendicularity pakati penzeve yakabhenda inokwira uye laser-yakachekwa inokwira pamusoro. Kugadzirisa kwanga kusiri kuomesera zvisungo-yaive yakarongeka-yakavakirwa dhizaini yakakiya datum mapoinzi muX, Y, * uye * Z panguva imwe chete.
Chokwadi 3D kugona kunoreva zvinhu zvitatu mukuita:
Modular base plates ine chaiyo-pasi T-slots uye inodzokororwa dowel pini nzvimbo (± 0.01 mm) Interchangeable locators-kwete mapini nekumira chete, asi kureba-inogadziriswa zvitsigiro, angular nest block, uye nekukurumidza-kuchinja-kusunga maoko ane calibrated torque retention. Integrated reference geometry, saka chikamu chese chinomhara chinopesana nendege imwechete yedatum, kwete pakatarisana nechero chikamu chisingaenderane. Izvi hazvisi dzidziso. Mune imwe purojekiti yemidziyo yekurima, kushandura kubva ku2D zvishandiso kuenda kune yakajairwa 3D fixture yakacheka weld kukanganisa ne63% uye yakaderedza post-weld kururamisa nguva kubva pamaminetsi gumi nemasere kusvika pasi pemasekonzi makumi mapfumbamwe pane imwe subassembly.
Chii chinoita kuti Fixture Ikwane-Kwete Kungobata
Vamwe vagadziri vanobata zvigadziriso senge static templates. Isu tinovabata sevanogonesa maitiro ekuita. Chigadziriso chinofanirwa kupona zviuru zvishanu+ matenderedzwa pasina kurasikirwa nekuvimbika kwenzvimbo. Inofanirwa kubvumidza kupinda kweMIG matochi, marobhoti welding misoro, uye post-weld yekuongorora-pasina kuda disassembly. Uye inofanira kuyera: imwechete base ndiro, akasiyana locators, kune prototype inomhanya yegumi nemashanu mayunitsi uye mabhechi ekugadzira zviuru zvitatu.
Isu takawana matatu asina-kutaurirana panguva chaiyo yekutumirwa:
Kugadzikana kwezvinhu: Hapana mabhesi esimbi anokandwa mushure mekudzokororwa kupisa bhasikoro. Isu tinoshandisa kushushikana-kudzoreredzwa 42CrMo4 alloy simbi kana anodized 7075-T6 aruminiyamu-yakaedzwa dimensional kudhiraivha pa80 ° C kwemaawa makumi manomwe nemaviri. Clamp simba kuenderana: Spring-loaded clamps inorasikirwa nekubata; pneumatic vanoda mitsara yemhepo. Yedu chiyero inoshandisa yakaomeswa simbi yekugezesa simbi ine yakanaka yekukiyiwa-yakasimbiswa pa12 kN inobata simba, inodzokororwa mukati ± 3% Serviceability: Vanopfeka vanopfeka. Pini dzinonamirwa. Saka yega yega 3D welding fixture inosanganisira inotsiviwa yakaomeswa inoisirwa-kwete-muchina-mukati maficha-uye yakazara BOM ine nguva dzekutungamira pasi pemaawa makumi manomwe nemaviri. Mumwe mutengesi wemotokari weNorth American Tier-1 akaramba chikumbiro chedu chekutanga nekuti marobhoti nzira yavo yekuronga yaida chaiyo TCP offset. Isu takaisa izvo zvinobvisa zvakananga mugadziriso yeCAD modhi-inounzwa se STEP mafaera ane GD&T callouts anoenderana neavo robhoti controller's coordinate system. Vakamhanya yekutanga-chidimbu kusimbiswa mumaawa 4.2.
Matangiro Akaita Kururama Pamberi Pekutanga Weld
Iyo 3D welding gadziriso haitsipire dhizaini isina kunaka-inoifumura. Isu takaongorora pamusoro pe200 yevatengi kudhirowa uko weld seams akayambuka mitsetse yakabhenda, zvichikonzera micro-kutsemuka munzvimbo dzakanyanya-kushushikana. Kana kuti uko mirwi yokushivirira yakaita kuti gungano rekupedzisira risaite—kunyange zvazvo chikamu chimwe nechimwe chaipfuura nokuongororwa.
Ndosaka tsigiro yedu yeinjiniya inotanga * isati yagadzirwa * yekugadzira:
DFM-inofambiswa weld seam kuiswa: Isu tinotevedzera kugovera kwekuisa kupisa uye kupa zano rekutamisa seam kuderedza kukanganiswa-kwakanyorwa nemamepu ekupisa. Datum zano rekuongorora: Ko yako yekutanga datum inoenderana nenzvimbo dzemachining? Nemitsara yekuparadzanisa? Nekudzika kweCMM yekuongorora nzvimbo? Tinoita mepu ese ari matatu Fixture-to-process handoff: Isu tinongopa kwete gadziriso chete, asi weld parameter masheets akasimbiswa pahukobvu hwezvinhu zvakafanana, mhando dzewaya dzekuzadza, uye majoyometries. Hapana "saizi-inokodzera-zvese" kits. Every 3D welding chigadziriso isu tinovaka tinotanga nezvinodiwa zvechikamu chako-kwete nhamba dzedu dzekatalogi.
Mhedzisiro Chaiyo, Kwete Benchmarks
KuBotou Haijun Metal Products Co., Ltd., tinoyedza zvigadziriso zviri pasi pemutoro-kwete chete huremu hwakamira, asi inoteedzerwa rhythm yekugadzira. Chigadziko chakatemerwa 3 mm mild steel chinofanirwa kuve chechokwadi kuburikidza ne100 akatevedzana tembiricha pa120 ° C ambient tembiricha, ine 3-second clamp actuation, uye 15-sekondi weld kugara - zvese zvakaiswa kuburikidza ne embedded strain geji uye kupisa kwekufungidzira.
Vatengi vedu vanotaura zvinoenderana mhedzisiro:
92% kuderedzwa kwekutanga-chinyorwa fit-up kugadzirisa Weld cycle time compression ye18-27%, yakasimbiswa nezvidzidzo zvekufamba-nguva Scrap rate inodonha kubva pa4.7% kusvika 0.3% pamagungano akaoma ane ≥7 weld joints Hatitengesi zvigadziriso. Isu tinoendesa kudzokororwa-kuyerwa mumamicrons, inotevedzwa mumaminitsi, yakavimbiswa mukunyora. Nekuti kana chigadzirwa chako chikafamba, chinosimudza, kana kutakura mutoro, weld haisi kungobatana chete. Ndiyo nheyo.
