Njira Yopangira Tungsten Carbide Yogaya Quills: Kuchokera Powder kupita ku Precision Tool

Tungsten carbide akupera quill ndi zida zofunika kwambiri pa ntchito yopera yolondola kwambiri, ndipo ntchito yake yapadera imachokera ku njira zabwino zopangira. Ulendo wochokera ku ufa wa micron kupita ku chida cholondola umaphatikizapo ndondomeko yoyendetsedwa bwino.

Kulinganiza kwazinthu Zopangira ndi Kusakaniza

Kupanga kumayamba ndi ufa wosankhidwa bwino wa tungsten carbide ndi cobalt ufa. Cobalt imagwira ntchito ngati gawo lomangira, ndipo zomwe zili mkati mwake zimakhudza mwachindunji kuuma ndi kulimba kwa chinthu chomaliza. Nthawi zambiri, zomwe zili mu cobalt zimachokera ku 6% mpaka 12%, zomwe zimagawidwa ndendende malinga ndi zofunikira za ntchito. Ma ufa a ma micron awa amakhala onyowa-osakanizidwa mu mphero za mpira kuti awonetsetse kugawidwa kofanana kwa molekyulu.

Kupanga Njira

slurry wosakanikirana amawumitsidwa-wouma mu granules zopanda madzi. Pambuyo pake, ukadaulo wokhazikika wozizira wa isostatic umagwiritsidwa ntchito kukakamiza zinthuzo pa 200-300 MPa. Panthawiyi, mawonekedwe a geometric a carbide akupera shaft amapangidwa, koma mphamvu imakhalabe yochepa, yomwe imafuna kukonzanso kwina.

Sintering process

Sintering ndiye njira yayikulu yopangira. M'ng'anjo za vacuum sintering, kutentha kumayendetsedwa bwino pamwamba pa malo osungunuka a cobalt (nthawi zambiri 1400-1500 ° C). Panthawi imeneyi, gawo la cobalt limasungunuka ndikunyowetsa tinthu tating'onoting'ono ta tungsten carbide, ndikupanga chomangira cholimba chazitsulo kudzera mumadzimadzi gawo sintering. Kuwongolera kolondola kwa curve yotenthetsera ndi nthawi yogwira ndikofunikira kuti zitsimikizike kuti kachulukidwe kokwanira ndikuwongolera kukula kwambewu.

Precision Machining

Sintered blank carbide grinding bar imalowa mgawo la makina olondola, omwe ndi ofunikira kuwonetsetsa kuti quill yoperayo ikukwaniritsa zofunikira. Makina opangira benchmark amapangidwa koyamba pogwiritsa ntchito ma grinders olondola kwambiri okhala ndi mawilo a diamondi kuti akhazikitse nsonga yolondola yolumikizirana, yokhala ndi kulolerana komwe kumayendetsedwa mkati mwa ± 0.01 mm.

Njira zazikuluzikulu zogaya zikuphatikizapo:

1. Kukonza shank ya chida: Kugwiritsa ntchito makina opukutira olondola kwambiri okhala ndi mawilo a diamondi, kuphatikiza kugaya movutikira, kumaliza pang'ono, ndi kumaliza. Kupera movutitsa kumachotsa zinthu zochulukirapo, kumaliza pang'onopang'ono kumakwaniritsa zofunikira, ndipo kumaliza kumatsimikizira kuuma kwa Ra ≤ 0.2 μm. Kulekerera kwa taper kwa HSK, CAPTO, ndi malo ena olumikizirana kuyenera kukhala mkati mwa ± 30".

2. Kukonza dzenje loziziritsa: Kugwiritsa ntchito zida zobowola dzenje lakuya ndiukadaulo wakubowola mfuti. Kuti muwonetsetse kuti khoma la dzenje likuyenda bwino, liwiro la chakudya (nthawi zambiri 50-100 mm/min) ndi kuzizira kozizira (10-15 MPa) ziyenera kuyendetsedwa bwino. Kulondola kwa dzenje m'mimba mwake kuyenera kufikira kalasi ya H7, ndi zolakwika zowongoka zosapitilira 0.02/100 mm.

3. Kusanja kwamphamvu: Kugwiritsa ntchito makina apadera olinganiza kuti asinthe kugawa kwaunyinji pochotsa zinthu molingana. Zofunikira zimaphatikizapo kukwaniritsa kalasi ya G2.5 ndi kusalinganika kotsalira pansi pa 1 g·mm/kg pa liwiro lalikulu la ntchito.

Kuyang'anira Ubwino

Kuyang'ana komaliza kumaphatikizapo kugwirizanitsa makina oyezera amiyeso ya geometric, ma laser interferometers a mawonekedwe ndi kulolerana kwa malo, makina ofananirako kuti ayese kuyesa kwamphamvu, ndi ma microscopes azitsulo posanthula kapangidwe kazinthu. Ndizinthu zokhazo zomwe zimapambana mayeso onse okhwima zomwe zitha kuperekedwa.

Njira yonse yopangira zinthu imaphatikiza matekinoloje angapo kuphatikiza zitsulo za ufa, makina olondola, komanso chithandizo cha kutentha. Kuwongolera kolondola pagawo lililonse limodzi kumathandizira kuti ma tungsten carbide agwire ntchito mwapadera. Makamaka mu gawo la makina olondola, kugwiritsa ntchito mokwanira ukadaulo wa zida zolimba kwambiri, ukadaulo woyezera mwatsatanetsatane, ndi ukadaulo wowongolera makina zimatsimikizira kulondola kwapang'onopang'ono kwapang'onopang'ono.

Zhuzhou Better Tungsten Carbide Company imatha kupereka ma quills apamwamba kwambiri, olondola a tungsten carbide akupera. Dikirani kukhudzana kwanu.
