Isithando somlilo sebhokisi indlela yokumisela iparameter

1. Ukumiselwa kobushushu beziko

Xa ukufudumeza ngokukhawuleza kusetyenziswa kwisithando somlilo, ubomi benkonzo yocingo oluchasayo luqwalaselwa. Ngokubanzi, iqondo lobushushu lomlilo libekwe kwi-920 ~ 940 ℃ (ucingo oluchasayo lwenziwe ngezinto ze-chromium-nickel), i-940 ~ 960 ℃ (i-restance wire yenziwe nge-iron-chromium-aluminium material) okanye i-960 ～980℃ (Intambo yokumelana yimathiriyeli equlethe amacandelo e-alloy afana ne-niobium kunye ne-molybdenum).

2. Ukumisela isixa somlilo esifakiweyo

Ubungakanani besithando somlilo esifakwe ngokuqhelekileyo sinqunywe ngokuhambelana namandla omlilo kunye nommandla wokusetyenziswa. Umgaqo ngulo: umphezulu wodonga lwesithando somlilo webhetshi yokuqala ye-workpieces ifikelele kwiqondo lokushisa elichaziweyo ngaphambi kokuba isithando somlilo sifakwe, kwaye ubushushu bomlilo bunokubuyela ngokukhawuleza kwiqondo lokushisa elichaziweyo emva kofakelo ngalunye. Ukuba umthwalo wesithando somlilo ukhulu kakhulu kwaye awuhambelani namandla omlilo, ukushisa kwesithando somlilo akuyi kubuyiselwa ixesha elide, okuya kuchaphazela ukuchaneka kwexesha lokubala. Kwimveliso yobuninzi, “inokuthi icuthwe ibe ngamacandelo” kwaye iqhutywe ngokuqhubekayo kwiibhetshi.

3. Ukuzimisela kwexesha lokufudumeza

Ixesha lokufudumeza elikhawulezayo libalwe ngokubanzi ngokobungakanani obusebenzayo becandelo lomnqamlezo we-workpiece, kwaye limiselwe ngokwemeko yokwenyani kunye namava adlulileyo:

(1) Ixesha lokufudumeza ngokukhawuleza kweqhekeza elinye lingabalwa ngolu hlobo lulandelayo:

t=intengiso

Apho t: ixesha lokufudumeza ngokukhawuleza (s);

a: Ukukhawuleza kwexesha lokufudumeza i-coefficient (s / mm);

d: I-diameter esebenzayo okanye ubukhulu be-workpiece (mm).

Kwisithando sokumelana nohlobo lwebhokisi, ububanzi obusebenzayo okanye ubukhulu be-workpiece bungaphantsi kwe-100mm, kwaye ixesha lokufudumeza ngokukhawuleza i-coefficient a yi-25-30s / mm;

Ububanzi obusebenzayo okanye ubukhulu be-workpiece bukhulu kune-100mm, kwaye ixesha lokufudumeza ngokukhawuleza i-coefficient a yi-20-25s / mm.

Bala ixesha lokufudumeza ngokukhawuleza ngokwefomula engentla, ekufuneka ilungelelaniswe ngokufanelekileyo ngokuhambelana nobushushu bomlilo obumiselweyo kwaye uzimisele emva kokudlula ukuqinisekiswa kwenkqubo.

(2) Xa iinxalenye ziveliswa ngeebhetshi, ukongeza ekubaleni le fomyula ingentla, ixesha lokufudumeza ngokukhawuleza kufuneka longezwe ngokomthamo wesithando somlilo esifakiweyo (m), ukuxinana kweziko kunye nendlela yokubeka:

Xa m＜1.5kg, akukho xesha longezwayo;

Xa m=1.5～3.0kg, yongeza i-15.30s;

Xa m=3.0～4.5kg, ezongezelelweyo 30～40s;

Xa m=4.5～6.0kg, yongeza 40～55s.
