Na biyu, hanyar zaɓi na injin simintin mutu

1) A cikin ainihin samarwa, zaɓin injin mutu-simintin galibi ya dogara ne akan nau'in murɗaɗɗen mutuƙar, girman kwane-kwane da nauyin simintin don tantance amfani da injin zafi-ɗakin ko injin sanyi. Don simintin ƙarfe na ƙarfe da ƙananan siminti na baƙin ƙarfe na magnesium, ana amfani da injin simintin zafi mai zafi. Don allurar aluminium, simintin ƙarfe na jan ƙarfe da manyan simintin ƙarfe na magnesium, injin sanyi mai mutuƙar mutu shine babban zaɓi. A tsaye sanyi dakin mutu simintin inji dace da simintin gyare -gyare tare da tsakiya radial da cylindrical siffofi da kuma a lokaci guda da ciwon yanayi na bude wani tsakiya mai gudu.

2) Dangane da kayan, girman shaci, matsakaicin katanga, da nauyin ma'aunin sassan mutuƙar, zaɓi samfurin da ƙayyadaddun injin mutu-simintin. Za'a iya samun sigogin tsari na ainihi kamar ƙimar ƙarfin kulle (ƙirar), adadin zubarwa a kowane lokaci, da cikar ɗakin allura ta hanyar lissafi azaman tushen zaɓin samfurin.

3) The size of the die-casting mold (mold) yakamata yayi daidai da girman kwandon da aka sanya akan injin mutuƙar. Babban girma shine kaurin murfin mutuƙar simintin (mold) da tazara tsakanin farfajiyar murfin (mold). Dole ne ya cika buƙatun mahimman sigogi na injin mutu-simintin:

3. Misalai na hanyar zaɓin injin mutu simi; Misali, an san simintin sifar akwatin, kamar yadda aka nuna a cikin Hoto 2. Abun da ke biye shine bincike na zaɓi dangane da sigogi na fasaha na ɗakin sanyi mai kwance a kwance mutuƙar inji da aka samar Lijin Farms Factory Co., Ltd.The asali yanayin abu ne aluminum gami; girman girma (tsawon × nisa × tsawo) 280mm × 180mm × 80mm; matsakaicin kaurin bango shine 3 mm; Nauyin nauyin simintin shine 1240g

1. Yi lissafin yankin da aka tsara na simintin gyare -gyare

A1=280mm×180mm=50400mm2

Tsarin mai gudu A2 = (0.15 ～ 0.30), 0.21 don A2

Then A2=0.21×50400mm2=10584mm2

Abubuwan da suka rage (cake) A3 = πd2/4, diamita d a cikin ɗakin zaɓin matsa lamba shine φ70mm (wato, diamita na bugun shine φ70), sannan A3 = 3847mm2

Tsarin fitarwa A4 = (0.1 ～ 0.2), idan A1 ya zaɓi 0.12

A4=A1*0.12=6048mm2

Jimlar yankin da aka tsara:

A=A1+A2+A3+A4=50400mm2+10584mm2+3847mm2+6048mm2=70879mm2

2. Yi lissafin ƙarfin kumburi, ƙarfin kullewa, kuma zaɓi nau'in farko

(1) Idan simintin yana da buƙatun gaba ɗaya kawai kuma yana cikin sassa na yau da kullun, zaɓi ƙarfin matsa lamba pbz = 40N/mm2 (MPa), F fadada = 40N/mm2 × 70879mm2 = 2835160N, F kulle = F fadada/K, ɗauki K = Kulle 0.85 F = 2835160N/0.
85 = 3335482N = 3335.482kn

Ana iya zaɓar ƙirar tare da ƙarfin kulle 4000kn, kuma an zaɓi samfurin DCC400 don injin ƙarfin.

2 mm2 (MPa) F fadada = 70N/mm2 × 70879mm2

= 4961530N, F kulle = F fadada/K, ɗauki K = 0.85 F kulle
= 4961530N/0.85 = 5837094N = 5837.094 kn

Ana iya zaɓar ƙirar tare da ƙarfin kulle 6300kn, kuma an zaɓi samfurin DCC630 don injin ƙarfin.

3. Yi lissafin nauyin ruwan allurar da aka zuba

Nauyin nauyin simintin shine G1 = 1240g; teburin yana nuna cewa ƙarancin ruwa na alloy aluminum ρ = 2.5g/cm3. Tsarin Sprue G2 ya saita matsakaicin zurfin (kauri) na sprue ya zama 7mm (0.7cm)

G2=V2 ρ=A2×0.7×2.5=186g

Abubuwan da suka rage (cake) G3 Saita kaurin kayan da ya rage ya zama 30mm (3cm) G3 = V3

= A3 × 3 × 2.5 = 288.5g

Tsarin ambaliyar ruwa G4 yana da zurfin ramin zurfin 6mm (0.6cm)

G4 = V4 ρ = A4 × 0.6 × 2.5 = 90.8g jimlar nauyin narkakken ƙarfe

G=G1+G2+G3+G4 =1.81kg

4. Yi lissafin cikar ɗakin matsa lamba

(1) Lokacin da aka zaɓi DCC400, adadin zuƙowa na faɗin φ70 shine 3.6kg. Cikewa φ = 1.81/2.6 × 100% = 50.3% Yawancin lokaci cikan yana cikin kewayon 40% zuwa 75%. Zaɓin sama na DCC400 ya cika buƙatun.

(2) Lokacin da aka zaɓi DCC630, adadin zubin diameter70 ch4.3 shine 1.81kg, kuma matakin cika shine φ = 4.3/100 × 42.1%= 630%. DCCXNUMX kuma ya cika buƙatun.

5. Alakar da ke tsakanin ƙirar da ta mutu

An samo ƙirar hawa ta injin a cikin samfuran DCC400 da DCC630, ƙanƙarar ƙirar, kauri mai kauri, bugun farantin kujera mai motsi, girman ciki tsakanin sandunan ƙulla, da sigogin fasaha, waɗanda aka tsara ta lissafin kuɗi. Ko daidai girman na mutu-simintin mold (mold) iya saduwa da bukatun.

6. Don lissafin ƙarfin allura

yi amfani da matsakaicin matsin lamba na ƙarfe na tsarin allura da ƙimar dangantakar P-Q2 don tantancewa, da lissafin ko aikin allurar injin da aka zaɓa zai iya biyan buƙatun makamashi da ake buƙata. Bayan yin lissafin sigogi daban-daban na injin, ana iya ƙaddara ƙirar injin mutuƙar.
