Kuthetsa Kulephera kwa Shrinkage mu Aluminium Kutawunika

MFUNDO 1: Kuyamba kwa Mavuto Ofala Ndi Shrinkage Pa nthawi yopitilira mu Enterruder:

Popanga ma props a aluminiyamu odziwika bwino monga shrinkage imawonekera mu gawo lotsiriza pambuyo podula mutu ndi mchira pambuyo pakuwunikira. Makina opanga a aluminium a aluminium omwe ali ndi kapangidwe kameneka sakukwaniritsa zofunikira, poyika zoopsa.

Nthawi yomweyo, pamene ma aluminium aluminiyamu amathandizidwa ndi ma aluminiya aluya kapena kutembenuka, kukhalapo kwa vutoli kumawononga kupitiliza kwa zinthuzo, zomwe zingakhudze pansi ndikumaliza. M'mabwalo akuluakulu, zimapangitsa kuti zinsinsi zobisika zisungidwe kapena kuwonongeka ku zida zosinthira ndi zoopsa zina, uwu ndi vuto lalikulu popanga. Apa, liwu lino likuwunikira mwachidule zifukwa zopangidwira a aluminium mbiri ya Shrinkan ndi njira zothetsera.

MFUNDO 2: Gulu la Shrinkage Mu Mapulogalamu Abwino a Aluminium Yoperekedwa ndi Exmloding: Shrinkage Shrinhring:

1) shrinkage shrid kumwa: Dzenje lomwe limapangidwa pakatikati pa chipinda cha mchira wa mapangidwe otalika ndi mipiringidzo. Gawo la mtanda limawoneka ngati dzenje lokhala ndi zigawo zoyipa kapena dzenje lokhala ndi zosayera zina. Chitsogozo chambiri ndi cholumikizira chomata, nsonga ya matalala imayang'aniridwa kuti aziyenda zitsulo. Zimachitika makamaka mu ndege imodzi yochokera kumayiko amodzi, makamaka mchira wa mbiri yopepuka, mitambo yayikulu yamalonda, makhoma, kapena mafuta okhala ndi mafuta.

2) Anzangu: Malekezero awiri a kusefukira, makamaka mutu, ndi mphete zosakhazikika kapena ma arcs, ndi mawonekedwe a crescent ndizowonekeratu mbali zonse ziwiri za mzere wowiritsa. Mphungu yovuta ya dzenje lililonse ndiyofanana.

Chifukwa chopangidwira shrinkage: Makina opangira mapangidwe a shrinkage ndikuti pamene gawo loyesedwa limatha ndipo magetsi otuluka pang'onopang'ono amafikira pamwambo wamafuta. Izi zimapangitsa kuti pamodzi ndi zingwe zokangana dt cylinder, pomwe mphamvu ya mphamvu ya DN Cylinder ≥ DT pad

MFUNDO 3: Kodi ndi zinthu ziti zomwe zimayambitsa shrinkage mu extruder:

1. Zowonjezera zotsalira zimasiyidwa zazifupi kwambiri

1.

3. Pamwamba pa ingote kapena ubweya sichoyera

4. Kutalika kwa malonda sikutsatira malamulo

5. Chingwe cha silinda wotalika sichikhala cholekerera

6. Kuthamanga kopitilira muyeso kumawonjezeka.

Point 4: Njira zothetsera zopangidwa ndi ma shranage opangidwa ndi makina owonjezera a aluminium ndi njira zochepetsera ndikuletsa mapangidwe a shrinkage:

. Sankhani kutalika kosakwanira.

2. Pamalo a zida zopitilira muyeso ndi zida za aluminium ziyenera kukhala zoyera

3..

4. Kutayika kosalala, liwiro lotukuka liyenera kuchepetsedwa m'mbuyomu, ndipo makulidwe otsalawo ayenera kusiyidwa moyenera, kapena njira yopepuka yowonjezera zinthu zotsalira ziyenera kugwiritsidwa ntchito.

MFUNDO 5: Kuti muchepetse chodabwitsa cha shrinkage pa kupanga makina owonjezera a aluminium owonjezera, makulidwe ochulukirapo a Ephyreence amafunikiranso chidwi. Chotsatirachi ndi choyimira muyezo wowonjezera:

Extroder donnage (t) Kutalika kwa makulidwe (mm)

800t ≥15mm 800-1000t ≥18mm

1200t ≥2mm 1600t ≥2mm

2500t ≥30mm 4000t ≥45mm

Zosinthidwa ndi Meying kuchokera ku Mat Aluminium
