Core shooting jak ni a madung daw ni hte jai lang ai lam ni.
Core shooting jak gaw, dai ni na aten na foundry hpaga lam hta, sand core ni hpe galaw shapraw na matu jai lang ai madung arung arai ni rai nga ai. Dai sand core gaw, n-gup magap kata kaw tawn da ai madung daw langai rai nna, casting a kata na n-gup magap ni (hka htung ni hte channel zawn re ai) ni hpe galaw na matu re. Dai core shooting jak gaw, n-gun ja ai sand core ni hpe atsawm sha galaw lu nna, tsaw ai{2}}}pressure sand shooting hte lawan ai hku tsi lajang ai lam ni hku nna, grai hkrak ai hku galaw lu ai.
A. Core shooting jak a madung daw ni
Laksan hku nna, core shooting jak langai (grau nna, hot core box core shooting machine) hta madung hku nna lawu na system ni hpe lawm ai:
1. Main framework hte mold hpaw ai ladat
Rack: Kaja ai ngang kang ai hte ngang grin ai lam ra ai arung arai ni a madi shadaw ai hkrang masa.
Clamping mechanism: Dai hta shamu shamawt ai hkrang, n shamu n shamawt ai hkrang, lam madun ai column ni hte clamping cylinder ni hpe lawm ai. Shi a bungli gaw:
Mold closing: Ntsa hte lawu na core box ni hpe n-gun ja hkra dip nna, nhpu n-gun n-gun n-rawng ai aten hta n-gun n-htum hkra makawp maga u.
Mold locking: Sandblasting galaw ai shaloi, n-gun kaba hpe ninghkap lu na matu, n-gun rawng ai n-gun hpe jaw ya ai.
Mold hpaw ai lam: Sand core gaw ngang kang wa ai hpang, core box hpe hpaw nna, ngut sai sand core hpe shaw kau u.
2. Sandblasting system
Ndai gaw core shooting jak a "myit masin" rai nga ai.
Sand hopper: Raw nhpu hpe shinggrup da ai.
Sand injection valve: Hka n-gun hpe hkang ai switch.
Sand injection cylinder: Dai gaw hka hpe bang na matu nhpu hpe shinggyin tawn da nna, kata kaw exhaust plug langai mi nga ai.
Sand injection baw: Core box a nhpu bang ai port hte matut mahkai nna, nhpu rawng ai arung arai ni gaw core box hka htung de hkrak hkrak shang lu na matu re.
Bungli galaw ai lam a npawt nhpang: Compressed air hpe kalang ta hka htung kata de cylinder kata de bang dat ai majaw, cylinder kata na n-gun hpe grai jat wa shangun ai. Dai hpang, nhpu n-gun hpe n-gun ja ai hku pat da sai hka htung kata de lawan ladan bang nna, hka hkin gau baw hku nna core box a n-gup magap de lawan ladan bang nna, lawan ai hku hpring wa nna, n-gun shayawm ya ai.
3. Gas jaw ai ladat
Nbung npawt: ngang grin ai, hkyet ai hte san seng ai nbung hpe jaw u.
Pipelines hte control valve ni: pneumatic valve amyu myu (solenoid valve, throttle valve, etc.) ni lawm ai, n-gun, lwi ai lam hte aten hpe hkang na matu lang ai, nhprang arai ni hpe gap ai, n-gup hpaw ai, n-gup hpaw ai, n-gup hpaw ai hte hka lim ai zawn re ai pneumatic action yawng a n-gun, lwi ai lam hte aten hpe hkang ai.
.
Hot core box: Dai gaw shi hkum nan hta n-gun rawng ai, katsi ai hka htung (electric katsi ai hka htung (sh) gas katsi ai jak ni) hpe kata kaw bang da ai, law malawng gaw 200-300℃du hkra katsi ai.
Temperature control system: thermocouples, nbung laru hpe hkang ai, etc. ni lawm ai, core box a nbung katsi ai hpe hkrak hkra hkang lu na matu hte nhpu core hpe langai sha zawn gram lajang na matu jai lang ai.
5. Control system
Electrical control cabinet: core gaw PLC (Programmable Logic Controller) shing nrai, bungli galaw ai ni a computer re.
Human-machine interface (HMI) : Hkrun lam hkawm ai shaloi, parameter amyu myu hpe masat da nna madun na matu lang ai Touch screen ( sandblasting aten, tsi lajang ai aten, nbung katsi ai lam, n-gun, etc.) hte jak rung a bungli galaw ai masa hpe yu reng ai lam ni hpe galaw na matu jai lang ai.
Control system gaw lit la ai: galaw ra ai lam yawng hpe shi hkrai shi galaw na matu, tau hkrau hkyen lajang da ai program hte maren, automated galaw shapraw ai lam hpe lu la na matu hkyen lajang ai.
6. Core sample galaw ai ladat
Mold hpaw ngut ai hpang, dai hpe core box kaw na nhprang n-gun hpe shapraw kau na matu ejector rod mechanism hpe lang chye ai.
Advanced automated jak ni hpe mung, hka htung ni hpe shi hkrai shi la nna, conveyor belt ntsa e tawn da nna, hkum hkrang hpe hkum tsup hkra galaw lu na matu, jak rung a lata ni hpe bang da ai.
7. Hkamja lam hpe makawp maga ai ladat
Hkamja lam n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-rawng ai chyinghka ni: Masha ni hpe hkrit tsang hpa shara ni de shang na matu pat shingdang u.
Hkyak hkyak hkring na matu button: Hkyak hkyak galaw ai lam hpe kalang ta jahkring kau u.
Interlock jak: Hka san seng ai zawn re ai hkrit tsang hpa bungli ni hpe shim lum lam chyinghka pat da ai shaloi sha galaw lu na hpe sadi jaw ai.
B. Core shooting galaw ai jak ni a jai lang ai lam ni
Core shooting jak hte galaw shapraw ai sand core ni hpe madung hku nna magri n-gang ni hpe galaw na matu lang ai, shanhte a application field ni gaw grai dam lada ai, grai sawng ai kata na n-gup magap ni hpe ra ai casting yawng ngu na daram hpe galaw shapraw ai lam hpe shinggrup da ai.
1. Tinang hkrai galaw shapraw ai hpaga lam (law dik htum ai ginra)
Engine: Cylinder block, cylinder baw jacket core, sau lam n-gun, lu sha ai hte n-gun dat ai lam hpe n-gun dat ai lam ni hta grai yak hkak ai hte grai tsaw ai hkrak ai lam ni hpe ra sharawng ai. Core shooting jak gaw, masha law law hpe atsawm sha galaw lu ai arung arai langai sha rai nga ai.
Hkamja lam: Hka lim ai nta a n bung ai n-gun n-gun ni hte sau circuit ni.
Chassis daw ni: steering gear nta a hka htung zawn re ai ni.
2. Kata kata wan hkru ai jak ni hte diesel engine ni hpe galaw shapraw ai
Cylinder block hte cylinder baw ni hpe sanghpaw li, mawdaw kaba ni hte gap ai jak ni hta lang ai diesel engine kaba ni a matu casting galaw ai.
3. Hydraulic arung arai ni hpe galaw shapraw ai bungli
Hydraulic valve block: Shi hta lai di ai hte n-gun ja ai sau circuit channel law law hpe kata kaw bang da nna, ndai channel yawng ngu na daram gaw nhpu core ni hte byin pru wa ai.
Pump nta ni, mawdaw nta ni: hka lim ai lam amyu myu nga ai.
4. Mung kata na Machinery hte Aerospace
Compressor, pump hkum hkrang: Grai sawng ai shell casting amyu myu.
Aerospace: turbine nta ni zawn re ai, n-gun kaba ai n-gun n-gun (performformance) ni hpe galaw ai.
5. Hardware pipe hta bang ai lam ni hte sumla hkrung galaw ai lam
Faucet, valve: kata na hka lam.
Hkrang: Sand core hpaji hpe mung daw nkau mi hta lang ai.
C. Core shooting jak ni a akyu ni
Hpa majaw nga yang, n-gun ja ai lam: sandblasting galaw ai lam gaw second 1 kaw nna 3 daram sha ra ai, galaw shapraw ai lam yawng (sandblasting - hpe {{3} demolding) gaw, second shi daram sha na ai aten du hkra minit loi mi du hkra sha nga ai majaw, masha law law hpe galaw shapraw na matu grai htuk manu ai.
Hpa majaw nga yang, n-gun kaba ai{0}} pressure sandblasting gaw, sand core a galu kaba ai lam hpe hkrak hkra galaw ya lu ai, ntsa lam gaw n-gun n rawng ai hte contour hpe asan sha galaw ya lu nna, grai sawng ai hkrang ni hpe bai gram lajang ya lu ai.
Outstanding performance: Gap ai majaw byin pru wa ai sand core gaw, n-gun ja ai hte n-gun kaja nga ai, molten metal hpe ru bang ai shaloi, n-gun n rawng ai (sh) n-gun n rawng ai majaw, casting a kata na n-gun atsam hpe hkam la lu ai.
Automation of automation: jak rung lata, conveyor lines, etc. ni lawm ai automated unit langai hpe hpaw na matu loi ai, bungli galaw ai lam hpe shayawm ya nna, galaw shapraw ai lam a ngang grin ai lam hte shim lum lam hpe grau kaja hkra galaw na matu loi ai.
Gadun dawk
Core function: Resin sand hpe katsi ai core box de bang na matu high{0}}pressure gas hpe jai lang nna, casting galaw na matu sand core ni hpe lawan ladan ngang kang hkra galaw ya ai.
Madung daw ni: Mold hpaw ai ladat, nhprang wan htu ai ladat, gas jaw ai ladat, nbung katsi ai ladat, hkang zing ai ladat, core sample hkam la ai ladat, shimlam masa.
Core application ni: Mawdaw engine/gearbox, diesel engine, hydraulic valve block, pump hkum hkrang, compressor, etc.
Madung akyu ni: Kaja ai lam grai kaja ai, hkrak ai hte n-gun kaba ai automation. Dai gaw, dai ni na aten na hkrak hkrak masat da na matu n mai malap ai ahkyak ai arung arai langai mi re.
