Incamake y'uburyo Valve Casting ikoreshwa

1. Gutera umupira ni iki?

Icyuma gisukwa mu mwobo w'ibumba ufite ishusho ikwiriye igice, kandi nyuma yo gukomera, haboneka igice cy'umusaruro gifite imiterere runaka, ingano n'ubwiza bw'ubuso, ari byo byitwa gusimbuza. Ibintu bitatu by'ingenzi: alloy, modeling, pouring na gukonjesha. Akamaro kanini: ibice bigoye bishobora gukorwa.

2. Iterambere ry'uburyo bwo gukata

Umusaruro watangiye mu myaka ya 1930 hakoreshejwe imashini zikora umwuka n'imitako y'umucanga w'ibumba ry'ubukorano.

Ubwoko bw'umucanga wa sima bwagaragaye mu 1933

Mu 1944, ubwoko bw'igishishwa cy'umusenyi gikonje cya resin cyagaragaye

Ifu y'umucanga w'ibirahuri by'amazi bya CO2 yagaragaye mu 1947

Mu 1955, ubwoko bw'igishishwa cy'umucanga cya resin cyagaragaye

Mu 1958, hagaragaye ifuru y'umucanga idatwikwa na furan resin

Mu 1967, hagaragaye ibumba ry'umucanga utemba sima

Mu 1968, hagaragaye ikirahure cy'amazi gifite icyuma gikomeretsa kikomoka ku bimera

Mu myaka 50 ishize, uburyo bushya bwo gukora ibumba rikozwe mu buryo bw'umubiri, nko: gushushanya icyuma gikozwe mu buryo bwa magnetic pellet, uburyo bwo gushushanya mu buryo bwa vacuum, gushushanya ifuro ryatakaye, nibindi. Uburyo butandukanye bwo gushushanya bushingiye ku ibumba rikozwe mu byuma. Nk'ibumba rikozwe mu buryo bwa centrifugal, gushushanya mu buryo bw'umuvuduko mwinshi, gushushanya mu buryo bw'umuvuduko muto, gusohora amazi mu mazi, nibindi.

3. Ibiranga uburyo bwo gushushanya

A. Guhindura ibintu mu buryo burambuye no koroherwa. Ibikoresho byose by'icyuma. Gucukura ntibigengwa n'uburemere, ingano n'imiterere y'igice. Uburemere bushobora kuva kuri garama nke kugeza kuri toni amagana, ubugari bw'urukuta bushobora kuva kuri 0.3mm kugeza kuri 1m, kandi imiterere ishobora kuba ibice bigoye cyane.

B. Ibikoresho byinshi by’ibanze n’iby’inyongera bikoreshwa bituruka ahantu henshi kandi bihendutse, nk’ibyuma bishaje n’umucanga.

C. Gukata bishobora kunoza imiterere y’ibipimo n’ubwiza bw’ubuso bw’ibikata binyuze mu ikoranabuhanga rigezweho ryo gukata, ku buryo ibice bishobora gukata bike kandi nta gukata.
