Iharurwa rya Casting Igihe cyo gukonjesha

Mu rwego rwo gukumira imyanda idashobora guhinduka, guturika nizindi nenge bitewe no gukonja byihuse nyuma yo gusuka, no kwemeza ko casting ifite imbaraga nubukomezi buhagije mugihe cyo gusukura umucanga, casting igomba kugira igihe cyo gukonjesha gihagije. Gukomeza gukorerwa ibishushanyo bigomba gutegurwa hamwe nuburebure buhagije bwo gukonjesha kugirango hamenyekane igihe cyo gukonjesha.

Igihe cyo gukonjesha mugihe cyo gukinisha gifitanye isano nibintu byinshi nkuburemere, uburebure bwurukuta, ubunini, ubwoko bwimvange, imiterere yububiko, imiterere yumusaruro nibindi bintu bya casting.

Time Igihe cyo gukonjesha ibice byuma bikozwe mumucanga

Igihe cyo gukonjesha ibice byicyuma mubibumbano byumucanga bigenwa ukurikije ubushyuhe iyo bipakurura. Urashobora kwifashisha amakuru akurikira: 300-500 ° C kubakinnyi rusange; 200-300 ° C kuri casting ikunda gukonja no guhinduka; 200-300 ° C kuri casting zikunda guturika Ubushyuhe Ubushyuhe ni 800-900 ℃. Ako kanya nyuma yo gupakurura, kura riser isuka hanyuma usukure umusenyi, hanyuma ubishyire mumwobo ushushe cyangwa winjire mu itanura kugirango ukonje buhoro.

1 time Igihe cyo gukonjesha ibice byicyuma mububiko bwumucanga birashobora gutoranywa ukoresheje Imbonerahamwe 11-2-1 na Imbonerahamwe 11-2-3.

Imbonerahamwe 11-2-1 Igihe cyo gukonjesha cyo hagati na bito bito mu mucanga

Gutera ibiro / kg	<5	5 ~ 10	10 ~ 30	30 ~ 50	50 ~ 100	100 ~ 250	250 ~ 500	500 ~ 1000
Gutera urukuta rw'uburebure / mm	<8	<12	<18	<25	<30	<40	<50	<60
Igihe cyo gukonja / min	20 ~ 30	25 ~ 40	30 ~ 60	50 ~ 100	80 ~ 160	120 ~ 300	240 ~ 600	480 ~ 720

Icyitonderwa: Kubitera hamwe nurukuta ruto, uburemere bworoshye nuburyo bworoshye, igihe cyo gukonjesha kigomba gufatwa nkigiciro gito, bitabaye ibyo, igihe cyo gukonjesha kigomba gufatwa nkigiciro kinini.

Imbonerahamwe 11-2-2 Igihe cyo gukonjesha ibintu binini mu mucanga

Gutera ibiro / t	1 ~ 5	5 ~ 10	10 ~ 15	15 ~ 20	20 ~ 30	30 ~ 50	50 ~ 70	70 ~ 100
Igihe cyo gukonja / h	10 ~ 36	36 ~ 54	54 ~ 72	72 ~ 90	90 ~ 126	126 ~ 198	198 ~ 270	270 ~ 378

Icyitonderwa: Mugihe cyo kwerekana imyobo, igihe cyo gukonjesha gikenera kwiyongera hafi 30%.

Imbonerahamwe 11-2-3 Igihe cyo gukonjesha mumucanga wumucanga wo hagati na ntoya mugihe cyo gusuka

uburemere / kg	<5	5 ~ 10	10 ~ 30	30 ~ 50	50 ~ 100	100 ~ 250	250 ~ 500
Igihe cyo gukonja / min	8 ~ 12	10 ~ 15	12 ~ 30	20 ~ 50	30 ~ 70	40 ~ 90	50 ~ 120

Icyitonderwa: 1. Gutera ibiro bivuga uburemere bwuzuye muri buri gasanduku

2 、 Kasting ikonjeshwa ku gahato no guhumeka ku murongo, kandi igihe cyo gukonja ni gito.

Igihe cyo gukonjesha mugihe cyo gukonjesha ibyuma birashobora kubarwa ukurikije formulaire ikurikira.

t = vG (2-1)

muri formula t —— Gutera igihe cyo gukonja （h）

v —— Gutera igipimo cyo gukonjesha, fata 4 ~ 8h / t

g —— Gutera ibiro (t)

k ni igipimo cyuburemere bwa casting nubunini bwacyo. Ninini ya k agaciro, ubunini bwurukuta rwurukuta rwa casting nigihe kinini cyo gukonja. Kubara formula ya k ni

k = G / V (2-2)

muri formula k —— Uburemere bwa casting hamwe nuburinganire bwacyo (t / m³);

G —— Uburemere bwa casting (t)

V —— Buhoro buhoro ingano ya kontour （m³）

Time Igihe cyo gukonjesha ibyuma bikozwe mu mucanga

Ibyuma byo gusukura umucanga wa hydraulic, gusukura umusenyi guturika hamwe nigikoresho cya pneumatike cyoza umucanga bigomba gukonjeshwa kugeza kuri 250-450 ° C mumucanga kugirango uhungabanye. Kugwa umucanga hejuru ya 450 ° C birashobora gutera deformasiyo no gucika muri casting. Igihe cyo gukonjesha mu mucanga kirashobora kugaragara ku gishushanyo cya 11-2-1 na Ishusho 11-2-3.

Mugihe ukoresheje amashusho atatu yavuzwe haruguru, ugomba kwitondera ingingo zikurikira:
