Hydraulic extrusion kugaya

Hydraulic extrusion grinding ndeyekuita semi-solid abrasive extruded kuburikidza nezvimwe zvikamu (zvakadai sepressure chamber uye jet hole), deburring, polishing uye chamfering of channel surface nekona, sezvinoratidzwa mumufananidzo 1. Muchina unogona kudzora extrusion pressure, abrasive kuyerera uye velocity. Mhando dzakasiyana dzekukuya, particle size, density uye mutakuri viscosity inogona kushandiswa kugadzira akasiyana extrusion kugaya mhedzisiro. Mutakuri anowanzo imhando yekuchinjika semi-solid polymer, ichiwedzera imwe huwandu hweabrasive musanganiswa. High viscosity pedyo-yakasimba inotakura inoshandiswa kuenzana kukuya masvingo emukati uye migero mikuru yezvikamu. Lower viscosity inowanzo shandiswa pakona chamfering uye diki chiteshi kugaya. Kana iyo abrasive ikadzvanywa mugero rakaganhurirwa, viscosity yeabrasive inowedzera, inobata kukwesha zvakasimba panzvimbo. Pane iyi viscosity, iyo abrasive ichakuya nzira kuburikidza. Iyo abrasive mass yakakora ne extrusion inoburitswa kuburikidza neyakaganhurwa chiteshi, ndiko kuti, yakajairika viscosity inodzoreredzwa, zvichikonzera kushoma kana kusagaya. Abrasive viscosity, extrusion pressure uye saizi yemugero inosarudza kuyerera kweabrasive, inokanganisa huwandu hwekukuya, kugaya kufanana, ukuru hwekona chamfering. Slow flow rate inokodzera kukuya yunifomu, kuyerera kwakanyanya kunoburitsa yakakura kutenderera kwekona. Extrusion pressure range ndeye 0.7 ~ 22MPa, abrasive flow rate inopfuura 3801/min. Chinonyanya kushandiswa kukwesha isilicon carbide, asi cubic boron nitride, alumina uye emery zviripo zvakare. Saizi yejecha zvidimbu zvinobva pa0. 005 kusvika 1.5mm. Jecha rakanaka rinogona kuwana kupedzisa kwepamusoro. Kudzika kwekucheka kunokonzerwa nejecha pane workpiece kunobva pane yakasarudzwa extrusion pressure, abrasive viscosity uye jecha saizi.
