Molding jak hpe garan ginhka ai lam

Molding jak ni hpe garan ginhka ai lam
Casting galaw na matu molding machine ni hpe nhprang wan hpe gara hku shinggrup da ai hpe madung tawn nna garan ginhka ai. Madung amyu bawsang ni gaw:压实 amyu, n-gun rawng ai compaction amyu, n-gun rawng ai hte n-gun rawng ai amyu, jet n-gun rawng ai amyu, static n-gun rawng ai amyu, nbung hkra ai amyu, hte nhpu kabai ai jak ni rai nga ai. Lahta na lam ni gaw, jak amyu shagu a npawt tara ni, akyu ara hte n kaja ai lam ni, jai lang mai ai lam ni hpe hkrak tup tsun dan da ai:
1.压实型造型机
Npawt tara: Nbung n-gun (sh) hka n-gun hpe lang nna, press head gaw, mould box kata na nhprang hpe n-gun dat nna, n-gun hpe hkrak sha bang ya ai. Madung hku nna masum nga ai: n-gun n law ai (<0.4MPa), medium pressure, and high pressure (>0.7MPa). Contact law law nga ai high-pressure amyu gaw madung rai nga ai.
-hpyen n-gun kaba ai amyu a akyu ni:
Nhprang wan n-gun tsaw ai hte maren sha re ai, n-gun ja ai casting size hkrak ai hte ntsa lam n-gun ja ai.
Multi-contact gaw yak hkak ai hkrang ni hpe hkan sa lu nna, n-gun shayawm ai lam gaw kaja ai.
Dai hkrang gaw loi loi sha rai nna, bungli galaw ai hte gram lajang ai lam ni hta mung loi ai.
Kaja wa lang ai flat press baw a n kaja ai lam ni:
Sand mold a ntsa hte lawu n bung ai n-gun n bung ai, sung ai daw hta n bung ai n-gun n rawng ai.
High-pressure amyu gaw manu kaba ai hte n-gun law law jai lang ai.
Hkamja lam hte seng nna: Labau kaba-scale, tsaw -htuk manu ai, law law galaw shapraw na matu yak hkak ai casting.
2. N-gun rawng ai (n-gun rawng ai hkra machyi ai lam) zawn re ai n-gun rawng ai jak
Npawt tara: Bungli galaw ai sha ku gaw, n-gun rawng ai n-gun hte nhpu n-gun ni hpe n-gun rawng hkra galaw na matu, n-gun rawng ai n-gun hte n-gun rawng ai n-gun hpe jai lang nna, n-gun rawng ai box hpe hkrat sum shangun nna, anvil dung shara hpe hkra shangun ai.
Vibration compaction zawn re ai n-gun rawng ai jak a akyu ni:
Structure asan sha, manu n law ai, galaw na matu loi ai.
N kaja ai lam ni:
Grai nsen kaba ai hte nhprang wan n-gun kaba ai.
Sand mold a n bung ai ntsa hte lawu n-gun n bung ai, ntsa daw a n-gun grai yawm ai.
Hpaji rawng ai lam n law ai, bungli galaw ai lam law ai, npawt nhpang hpe grai hkra machyi shangun ai.
Laksan jai lang mai ai mabyin masa ni: Madung hku nna yeng seng kau sai, asan sha, kaji-scale, hte n-gun n law ai-htuk manu ai casting ni a matu sha lang ai.
3. N-gun rawng ai hte n-gun rawng ai hku galaw ai jak (micro-n-gun rawng ai n-gun rawng ai jak hpe mung lawm ai)
Npawt tara: Shawng nnan, hkra machyi ai lam hpe shinggrup nna, dai hpang, dip ai hku nna jat bang ai; micro-n-gun rawng ai amyu gaw -n-gun kaba ai hte kaji ai-n-gun rawng ai + dip ai lam re.
Vibration hte pressure amyu hpan galaw ai jak a akyu ni:
Grau bung ai nhpu n-gun n-gun, san seng ai hkra machyi ai lam hta grau kaja ai quality.
Moderate manu, galai shai mai ai, law law lang ai.
Micro-vibration amyu gaw nsen hpe shayawm ya nna, npawt nhpang a matu ra ai lam ni hpe shayawm ya ai.
N kaja ai lam ni:
Nsen hte n-gun naw nga ai, jet n-gun hta grau n-gun yawm ai hte -n-gun kaba ai amyu.
Hkamja lam hte seng nna: Batch hte kaba-scale hku nna, lapran tsang-sized castings ni hpe galaw shapraw ai.
4. Jet n-gun hte galaw ai jak
Npawt tara: Hpa majaw nga yang, n-gun kaba ai nbung hpe jai lang nna, nhprang wan hpe lawan ladan jet bang nna, pre-compaction galaw na matu, dai hpang hydraulic pressing galaw ai; shi hpe -box / n lawm ai-box, dingyang / dingyang mold garan ai ngu nna garan da ai.
Jet pressure zawn re ai n-gun dat jak a akyu ni:
Hpaga galaw ai lam grai law ai (-box line n lawm yang hkying hkum mi hta mould 300-500 du hkra galaw lu ai).
Hkrang nsam tsaw ai, asan sha re ai, mold box n ra ai (-box n lawm ai), nhpu hte shara hpe hkye la ai.
Horizontal mold garan ai hta core hpe shim lum ai hku tawn da ai.
N kaja ai lam ni:
Manu dan ai arung arai ni, yak hkak ai hkrang masa, gram lajang na matu manu kaba ai.
Vertical mold garan ai hta core hpe tawn da na matu yak ai, asan sha re ai daw ni a matu sha htuk manu ai.
Sand quality a matu grai ngang kang ai ra kadawn ai lam ni.
Laksan hku nna, n-gun n rawng ai n-gun (valve hkum hkrang, pipe daw ni zawn re ai) hpe batch hte kaba -scale hku galaw shapraw ai.
5. N shamu n shamawt ai n-gun (nbung lwi ai hpe shinggrup ai) amyu hpan hpe galaw ai jak
Npawt tara: Nbung lwi ai shawng-compaction + hpang jahtum plate hpe dip ai hku nna dip ai.
Static pressure zawn re ai n-gun dat jak a akyu ni:
Grai tsaw ai hte maren sha re ai compactness, hkra machyi ai lam n nga ai, nsen n law ai, ga nhpu n law ai.
Kaja dik htum ai casting hkrak ai lam hte ntsa lam a hkam kaja lam, yak hkak ai n-gun n rawng ai-bunghku daw ni a matu htuk manu ai.
Template ntsa hta uniform n-gun, galu kaba ai magam bungli prat.
N kaja ai lam ni:
Manu kaba dik ai, hkang zing ai ladat yak hkak ai, nhprang hte bungli galaw na matu grai law ai ra kadawn ai lam ni nga ai.
Hkamja lam hte seng nna: High-end, hkrak ai, hte yak hkak ai casting ni a matu, tinang hkrai galaw ai ladat ni.
6. Nbung hkrat sum ai molding jak (nbung lwi ai hkrat sum ai)
Npawt tara: Kalang ta nbung laru gaw nhpu ntsa hta bungli galaw nna, nhpu n-gun ni a rheological fluidity hpe jai lang nna nhpu n-gun hpe shinggrup da ai.
Nbung n-gun hte galaw ai jak a akyu ni:
Lawan ai hte maren mara compacting speed, kaja ai maren mara, sung ai hka htung ni hte n-gun n rawng ai hka htung ni a matu kaja dik ai hka htung ni hpe jahpring ya lu ai atsam.
Nsen n law ai, jak n-gun n rawng ai.
N kaja ai lam ni:
Control yak hkak ai lam grai law ai, arung arai ni grai yak hkak ai, grai n lang ai.
Hkamja lam hte seng nna: Hkrak ai, sung ai hka htung, tsaw ai-htuk manu ai lapran tsang-sized castings (valve hkum hkrang, pipe daw ni zawn re ai).
7. Sand kabai ai jak
Npawt tara: High-speed shinggrup ai blade ni gaw nhpu hpe kabai bang kau ai, nhpu hpe kalang ta jahpring nna shinggrup ai.
Sand kabai ai jak a akyu ni:
Asan sha galaw da ai, grai n-gun ja ai hku galai shai lu ai atsam (sand box kaba / langai sha / n-gun ja ai casting).
Grau nna bung ai nhpu n-gun rawng ai.
N kaja ai lam ni:
Blade hpe lawan ai hku lang ai, n-gun law law jai lang ai, n-gun n law ai.
Sand grains ni gaw n-gun yawm mat chye nna, ga nhpu law law nga ai.
Hkamja lam: Kaba ai, n-gun ja ai, langai -/ kaji-batch casting ni a matu htuk manu ai.
