ʻO ka wili hydraulic extrusion

Hydraulic extrusion grinding mea e hana semi-solid abrasive extruded ma o kekahi mau wahi (e like me ka kaomi keena a me ka jet hole), deburring, polishing a chamfering o ka channel ili a me ke kihi, e like me ka hoike ana ma ka Figure 1. Hiki i ka mīkini ke hoʻomalu i ke kaomi extrusion, abrasive. kahe a me ka wikiwiki. Hiki ke hoʻohana ʻia nā ʻano wili like ʻole, ka nui o ka ʻāpana, ka nui a me ka viscosity lawe e hana i nā hopena wili extrusion. ʻO ka mea lawe ka mea maʻamau he ʻano polymer semi-solid maʻalahi, e hoʻohui i kahi nui o ka hui abrasive. Hoʻohana ʻia nā mea lawe viscosity kokoke i ka paʻa e wili like i nā paia o loko a me nā kahawai nui o nā ʻāpana. Hoʻohana pinepine ʻia ka viscosity haʻahaʻa no ka chamfering kihi a me ka wili liʻiliʻi. Ke ʻomi ʻia ka abrasive i loko o ke kahawai i kaupalena ʻia, piʻi ka viscosity o ka abrasive, paʻa paʻa i ka ʻōpala. Ma keia viscosity, e wili ka abrasive i ke alahele. Hoʻokuʻu ʻia ka nui abrasive mānoanoa e ka extrusion ma o ke kahawai i kaupalena ʻia, ʻo ia hoʻi, hoʻihoʻi ʻia ka viscosity maʻamau, e hopena i ka wili liʻiliʻi a ʻaʻole paha. ʻO ka viscosity abrasive, ka extrusion pressure a me ka nui o ke kahawai e hoʻoholo i ka kahe kahe o ka abrasive, e pili ana i ka nui o ka wili, ka wili like ʻana, ka nui o ka chamfering kihi. He kūpono ka wili liʻiliʻi no ka wili like ʻana, ʻo ke kahe kahe kiʻekiʻe e hoʻohua i ka pōʻai kihi nui. He 0.7 ~ 22MPa ka nui o ke kaomi Extrusion, ʻoi aku ka nui o ka kahe abrasive ma mua o 3801/min. ʻO ka ʻōpala maʻamau i hoʻohana ʻia he silicon carbide, akā loaʻa pū kekahi cubic boron nitride, alumina a me ka emery. ʻO ka nui o nā ʻāpana one mai 0. 005 a i 1.5mm. Hiki i ke one maikaʻi ke loaʻa ka hopena kiʻekiʻe. ʻO ka hohonu o ka ʻoki ʻana i hana ʻia e ke one ma ka mea hana ma muli o ke kaomi extrusion i koho ʻia, abrasive viscosity a me ka nui o ke one.
