Nekubatanidza iyo yekupedzisira-kumeso grooving cutter nebhiriji inofinha yekucheka muviri, yakakosha chishandiso chekupedzisira-chiso grooving chakagadzirwa uye kugadzirwa kutsiva yekupedzisira milling cutter, uye magumo-echiso grooves ezvikamu zvakakura zvezvimiro zvinogadziriswa nekufinha panzvimbo kugaya paCNC kaviri-mativi anofinha uye kumilling machining centre.
Mushure mekugadzirisa maitiro, iyo yekupedzisira yakatarisana ne groove nguva yekugadzirisa yakadzikiswa zvakanyanya, iyo inopa inoshanda nzira yekugadzirisa iyo yekupedzisira kumeso grooves yezvikamu zvakakura zvechimiro pane inofinha uye milling machining centre.
01 Nhanganyaya
Muzvikamu zvakakura zvezvimiro zvemichina yeinjiniya (ona Mufananidzo 1), zvakajairika kuwana magumo kumeso grooves mukati mebhokisi. Semuyenzaniso, gomo rekumagumo rinoratidzwa mu “Ⅰ rakakurisa” muchikamu cheGG cheMufananidzo 1 rine makuriro chaiwo: dhayamita yemukati inoita 350mm, dhayamita rekunze re365mm, gomo rakafara 7.5mm, uye kudzika kwegoro 4.6mm.
Tichifunga nezve basa rakakosha rekupedzisira face groove mukuisa chisimbiso uye mamwe mabasa emuchina, zvakakosha kuti uwane yakakwirira kugadzirisa uye kurongeka kwechokwadi [1]. Naizvozvo, post-weld processing yezvimiro zvemukati inodiwa kuti ive nechokwadi chekuti yekupedzisira face groove inosangana nehukuru hunodiwa hwakatsanangurwa mudhirowa.
Iyo yekupedzisira-yechiso groove yeinotenderera workpiece inowanzogadziriswa uchishandisa lathe ine yekupedzisira-kumeso groove cutter. Iyi nzira inoshanda kune dzakawanda zviitiko.
Zvisinei, kune zvikamu zvakakura zvekugadzirisa zvine maitiro akaoma, hazvibviri kushandisa lathe. Mumamiriro ezvinhu akadaro, nzvimbo inofinha uye yekugaya machining inoshandiswa kugadzirisa iyo yekupedzisira face groove.
Iyo tekinoroji yekugadzirisa yeiyo workpiece muMufananidzo 1 yakagadziridzwa uye yakagadziridzwa nekushandisa kufinha pachinzvimbo chekugaya, zvichikonzera zvakanyanya kunatsiridza kupera-kumeso groove kugadzirisa kunyatsoita.
02 Gadzirisa tekinoroji yekumberi kumeso kwegroove kugadzirisa
Zvinhu zvechikamu chechimiro chinoratidzwa muMufananidzo 1 is SCSiMn2H. Iyo yekupedzisira face groove yekugadzirisa michina inoshandiswa iCNC yakapetwa-mativi anofinha uye milling machining centre ine Nokia 840D sl inoshanda system. Chishandiso chiri kushandiswa ndeye φ6mm yekupedzisira chigayo, uye nzira yekutonhodza inoshandiswa ndeyekutonhodza mhute yemafuta.
End face groove processing technique: Maitiro acho anosanganisira kushandisa φ6mm yakakosha yekupedzisira mill ye spiral interpolation milling (ona Mufananidzo 2). Pakutanga, kugaya kwakashata kunoitwa kuti pave nehudzamu hwe2mm, kuchiteverwa nekusvika pakadzika 4mm, kuchisiya 0.6mm yekugaya zvakanaka kwegoro. Iyo rough milling program inotsanangurwa muTable 1. Fine milling inogona kuitwa nekugadzirisa kucheka paramita uye spiral interpolation coordinate values muchirongwa. Iyo yekucheka maparameter ekugayo rough uye yakanakaCNC milling chaiyozvinotsanangurwa muTafura 2.

Tafura 2 Kucheka zvimiro zvechiso slot milling
Zvichienderana netekinoroji yekugadzira uye maitiro, φ6mm yekupedzisira chigayo inoshandiswa kukuya kumeso slot ine hupamhi hwe7.5mm. Zvinotora 6 majana ekududzira kutenderera kwegayo uye 3 majana ekugaya zvakanaka. Kugaya zvine dhayamita hombe kunotora maminetsi gumi nemapfumbamwe pakutendeuka, ukuwo kugaya kunotora maminetsi gumi nemana pakutendeuka. Nguva yese yekugaya nekugoyora inosvika maminetsi zana nemakumi mashanu nematanhatu. Kushanda kwe spiral interpolation slot milling kwakadzikira, zvichiratidza kudiwa kwe process optimization nekuvandudza.
03 Gadzirisa iyo yekupedzisira-chiso groove kugadzirisa tekinoroji
Maitiro ekupedzisira-kumeso groove kugadzirisa pane lathe anosanganisira workpiece inotenderera nepo yekupedzisira-chiso groove cutter ichiita axial feeding. Kana iyo yakatsanangurwa groove kudzika kwasvika, radial feeding inowedzera iyo yekupedzisira-kumeso groove.
Yekupedzisira-kumeso groove kugadzirisa pane inofinha uye yekugaya machining centre, yakakosha chishandiso chinogona kugadzirwa nekubatanidza yekupedzisira-chiso groove cutter uye bhiriji rinofinha rekucheka muviri. Mune ino kesi, iyo workpiece inoramba yakamira apo yakakosha chishandiso ichitenderera uye kuita axial feeding kupedzisa kupera-kumeso groove kugadzirisa. Iyi nzira inonzi boring groove processing.

Mufananidzo 4 Schematic dhayagiramu yemusimboti wekugadzira wekupedzisira face groove pane lathe
Iyo chaiyo yemechani zvikamu zvakagadziriswa nemachina-akarovererwa mablades muCNC anofinha uye milling machining nzvimbo anogona kazhinji kusvika IT7 uye IT6 mazinga. Pamusoro pezvo, iwo matsva e grooving blades ane yakakosha kumashure angle chimiro uye akapinza, izvo zvinoderedza kucheka kuramba uye kudedera. Iwo machipisi anogadzirwa panguva yekugadziriswa anogona kukurumidza kubhururuka kubva kune iyomichina yakagadzirwapamusoro, zvichiita kuti pave nepamusoro pepamusoro.
Hunhu hwepamusoro hweiyo milling yemukati gomba groove inogona kudzorwa nekugadzirisa akasiyana ekucheka maparamendi akadai seyekudya kumhanya uye kumhanya. Iyo yekupedzisira yakatarisana ne groove chaiyo yakagadziriswa neiyo machining centre uchishandisa yakakosha groove cutter inogona kusangana nemazvo ekudhirowa zvinodiwa.
3.1 Dhizaini yechishandiso chakakosha chekugadzirisa groove kumeso
Dhizaini iri muFigure 5 inoratidza chishandiso chakakosha chekugadzirisa magororo ekumeso, akafanana nebhiriji rinofinha chishandiso. Chishandiso ichi chinosanganisira bhiriji rinofinha chishandiso muviri, inotsvedza, uye isiri-yakajairwa mudziyo inobata. Iyo isiri-yakajairwa mudziyo inobata ine chibatiso, chibatiso chemudziyo, uye grooving blade.
Iyo bhiriji inofinha chishandiso muviri uye inotsvedza ndeye yakajairwa maturusi emidziyo, uye chete isiri-yakajairwa mudziyo inobata, sezvakaratidzwa muFigure 6, inoda kugadzirwa. Sarudza yakafanira grooving blade modhi, isa blade paface groove tool holder, batanidza isiri-standard tool holder kune inotsveyamisa, uye gadzirisa dhayamita yeface groove tool nekufambisa muteresi.
Mufananidzo 5 Kuumbwa kwechishandiso chakakosha chekupedzisira face groove processing
3.2 Kugadzira iyo yekupedzisira face groove uchishandisa yakakosha chishandiso
Chishandiso chehunyanzvi chekugadzira groove yekumagumo inoratidzwa muMufananidzo 7. Shandisa chiridzwa chekumisikidza kuti ugadzirise chishandiso kune chakakodzera dhayamita yegroove nekufambisa muteresi. Rekodha kureba kwechishandiso uye pinda dhayamita yechishandiso uye kureba mutafura inoenderana pamuchina wepaneru. Mushure mekuedza workpiece uye kuona kuti zviyero zvakarurama, shandisa nzira inofinha maererano nechirongwa chekugadzira chiri muTebhu 3 (ona Mufananidzo 8).
Iyo CNC chirongwa chinodzora kudzika kwegorofu, uye iyo yakaoma machining yekuguma kwechiso groove inogona kupedzwa mune imwe inofinha. Kutevera hutsinye machining, kuyera groove saizi uye yakanaka-chigayo groove nekugadzirisa kucheka uye yakagadziriswa kutenderera paramita. Iyo yekucheka zvimiro zvekupedzisira face groove boring machining inotsanangurwa muTafura 4. Iyo yekupedzisira face groove machining nguva inenge 2 maminitsi.

Tafura 3 End face groove boring process
Mufananidzo 8 Kupedza face groove kufinha
Tafura 4 Kucheka ma paramita ekupedzisira kumeso slot anofinha
3.3 Implementation effect mushure mekuita optimization
Mushure mekugadzirisa iyoCNC kugadzira maitiro, iyo inofinha yekugadzirisa verification yemagumo echiso groove ye5 workpieces yakaitwa nguva dzose. Ongororo yezvishandiso zvebasa yakaratidza kuti iyo yekupedzisira yakatarisana ne groove kugadzirisa kurongeka kwakasangana nezvinodiwa zvekugadzira, uye chiyero chekupasa chekuongorora chaive 100%.
Iyo data yekuyera inoratidzwa muTafura 5. Mushure menguva yakareba yebatch processing uye kuvimbiswa kwehutano hwe20 box end face grooves, yakasimbiswa kuti kuguma kwechiso che groove kururamisa kwakagadziriswa nenzira iyi kunosangana nezvinodiwa zvekudhirowa.
Iyo yakakosha yekugadzirisa chishandiso chekupedzisira kumeso grooves inoshandiswa kutsiva yakakosha yekupedzisira mill kuitira kuvandudza kuomarara kwechishandiso uye kuderedza zvakanyanya nguva yekucheka. Mushure mekuita optimization, iyo nguva inodiwa yekupedzisa face groove processing inoderedzwa ne98.7% kana ichienzaniswa nepamberi pekugadzirisa, zvichitungamira kune yakanyanya kunatsiridza mashandiro ekugadzirisa.
Iyo grooving blade yechishandiso ichi inogona kutsiviwa kana yasakara. Iine mutengo wakaderera uye hupenyu hwesevhisi hurefu kana ichienzaniswa neyekupedzisira chigayo. Chiitiko chinoshanda chakaratidza kuti nzira yekugadzirisa magumo-echiso grooves inogona kusimudzirwa zvakanyanya uye kugamuchirwa.
