Kulemekeza Popanga Ma Shaft Olondola

1. Chifukwa Chiyani Makina Ochizira Amafunikira

Miyendo yolondolandi zigawo zofunika zomwe zimagwiritsidwa ntchito pamakina, makina amagalimoto, ma hydraulics, ma robotics, ndi misonkhano yazamlengalenga.
Nthawi zambiri amakhala ngatikukweretsa ziwalondi zitsamba, zimbalangondo, kapena zisindikizo, kumenekumaliza pamwamba, kuzungulira, ndi kuwongokazimakhudza mwachindunji magwiridwe antchito.

Ngakhale pambuyokutembenuka, kugaya, kapena kutembenuka mwamphamvu, pamwamba pa shaft ikhoza kukhala ndi:

Nsonga zazing'ono ndi zigwa(kukhwinyata kwapamwamba kwambiri kuti sikungathe kusindikizidwa kapena kukhudzana).

Zolakwika za mawonekedwemonga taper, mbiya, kapena ovality.

Zotsalira zotsalirakuchokera pakupera kapena kutentha kutentha.

Makhalidwe osagwirizana ndi mafutapamwamba.

Zolakwika izi zitha kuyambitsa:

Kuvala kwambiri kwa ma bearing kapena zisindikizo,

Kutaya kwa ma hydraulic systems,

Phokoso kapena kugwedezeka panthawi yozungulira, ndi

Kuchepetsa kutopa moyo wa shaft.

Chifukwa chake, kuyatsa kumagwiritsidwa ntchito:

Kukwaniritsamicron-kulondola kwa mulingom'mimba mwake, mozungulira, ndi mowongoka.

Pangani akumalizidwa pamwambandi roughness yeniyeni ndi kapangidwe kapangidwe.

Chotsani kupotoza pamwamba ndi mphesa zopsereza.

Kupititsa patsogolokatundu-malo onyamulandikusungirako mafuta.

Wonjezeranikutopa mphamvu ndi kuvala kukanawa shaft.

2. Ntchito za Honing Machine mu Shaft Production

3. Momwe Honing Process imachitikira (Step-by-Step)

Khwerero 1: Pre{1}}Kukonza

Shafts ndianatembenuka, malo opanda pakati, kapenapansi pa cylindricalmpaka kukula pang'onowokulirapo(nthawi zambiri ndi 0.02-0.1 mm).

Cholinga ndikusiya katundu wocheperako kuti akule.

Gawolo likhoza kukhalakutentha-kuchiritsidwa(kwa kuuma) musanamalize.

Khwerero 2: Kukhazikitsa & Kukonza

Shaft imayikidwapakati pa malo kapena mu chuck yolondolakuti mukhale ndi mayendedwe angwiro pamodzi ndi olamulira.

The honing mandrel kapena sleeve ndizogwirizana ndi coaxiallyku shaft.

Zosintha zimatha kupangitsa shafttembenuzani, zungulirani, kapena khalani chete, kutengera kapangidwe ka makina.

Khwerero 3: Kusankha Kwachida ndi Abrasive

Zakumeta kwakunja, manja abrasive kapena nsapato zimayikidwa pamutu wa honing womwe umatambasula mozungulira kuzungulira tsinde.

Zakulemekeza kwamkati(ngati shaft ili ndi bore), mandrel amkati okhala ndi miyala ya abrasive amagwiritsidwa ntchito.

Zida za abrasive wamba:

Aluminium oxide kapena Silicon Carbideza zitsulo.

CBN kapena Diamondiza aloyi olimba kapena chrome-zokutidwa.

Kutentha mafuta kapena emulsionamapereka mafuta, kuziziritsa, ndi kuchotsa chip.

Khwerero 4: Kuwongolera magwiridwe antchito

Makina owongolera amatha kuchitamayendedwe oyendetsedwa nthawi imodzi:

Kasinthasintha:Shaft kapena chida chimazungulira pa 100-500 rpm.

Kubwezerana:Chidacho kapena gawolo limayenda mozungulira kutalika kwa shaft (nthawi zambiri kuthamanga kwa sitiroko 10-30 m / min).

Radial Pressure:Nsapato zonyezimira zimagwiritsa ntchito kukakamiza koyendetsedwa kuti muchotse zigawo zazing'ono zazing'ono mofanana.

Pamodzi, zolimbikitsa izi:

Pangani acrosshatch chitsanzopamwamba (ngodya nthawi zambiri 30 digiri -45 digiri).

Chotsani nsonga zazitali ndikuyeretsa mawonekedwe akumaliza komaliza.

Zolakwika zamtundu wolondola zomwe zasonkhanitsidwa kuchokera kukupera kapena kukanikiza kupotoza.

Khwerero 5: Mu-Kachitidwe Kuwunika

Makina owongolera mwatsatanetsatane amagwiritsidwa ntchitomu-kachitidwe kayeji kapena makina oyezera mpweyakutsata kukula ndi kuzungulira mu nthawi yeniyeni.

Kuwongolera kwa CNC kumasintha kuthamanga, kuthamanga, ndi kutalika kwa sitiroko kuti mukwaniritse zomwe mukufuna ndikumaliza.

Khwerero 6: Final Finishing Pass

Finer-miyala ya grit (600–1200 grit) imagwiritsidwa ntchito podutsa pang'ono.

Cholinga chake ndi kumaliza kwapamwamba pakati pa:

Ra 0.05-0.2 µmkwa hydraulic kapena kubala shafts,

Rz Ochepera kapena ofanana ndi 1 µmkwa osindikiza malo.

Izi zimatsimikizira machitidwe abwino opaka mafuta komanso kuvala kochepa panthawi yogwira ntchito.

Gawo 7: Kuyeretsa ndi Kuyang'anira Ubwino

Pambuyo pa kutha, shaft imadutsa:

Akupanga kapena zosungunulira kuyeretsakuchotsa zotsalira za abrasive ndi mafuta.

Kuwunika kwa Metrology, kuphatikizapo:

Diameter ndi kuzungulira (mpweya woyezera kapena kugwirizanitsa makina oyezera)

Kuuma kwapamtunda (profilometer)

Kuwongoka ndi kuthamanga (chizindikiro choyimba kapena kuyanjanitsa kwa laser)

Zigawo zokhazo zomwe zimakwaniritsa njira zonse zolondola zimapitilira pakuyala, zokutira, kapena kuphatikiza.

4. Zoyimira Honing Magawo a Precision Shafts

5. Ubwino Wokulitsa mu Precision Shaft Manufacturing

Superior Surface Quality- Malo osalala, okwera amachepetsa kukangana ndi kuvala.

Kulondola Kwambiri Kwambiri- Imathandizira kusindikiza kapena kutsetsereka kokwanira ndi chilolezo chochepa.

Kukhathamiritsa kwa Chisindikizo Chokwezeka- Maonekedwe a Crossshatch amasunga mafuta ndipo amalepheretsa kutayikira.

Kulimbitsa Kutopa Kwambiri- Imachotsa ma microcracks ndi zokweza kupsinjika pakupera.

Kuchepetsa Phokoso ndi Kugwedezeka-Kuwongoka bwino komanso kuzungulira kumalimbikitsa kusinthasintha kosalala.

Moyo Wowonjezera Wautumiki- Ma shaft amakana kugoletsa, kukwiya, komanso dzimbiri bwino.

6. Mitundu Yamakina a Honing Omwe Amagwiritsidwa Ntchito Pamitsinje
