Isi ihe 1: Okwu mmalite nke nsogbu ndị a na-ahụkarị na mbelata n'oge usoro extruder nke extruder:
Na mmepụta extrusion nke profaịlụ aluminom, ntụpọ ndị a na-akpọkarị shrinkage ga-apụta na ngwaahịa agwụchachara mgbe ịchacha isi na ọdụ mgbe nyocha alkali etching gasịrị. Ihe eji arụ ọrụ nke profaịlụ aluminom nwere usoro a anaghị emezu ihe achọrọ, na-etinye ihe egwu nchekwa.
N'otu oge ahụ, mgbe a na-edozi profaịlụ aluminum alloy aluminom na-edozi n'elu ọgwụgwọ ma ọ bụ nhazi ntụgharị, ịdị adị nke ntụpọ a na-ebibi ihe dị n'ime ime ihe, nke ga-emetụta elu na njedebe na-esote. N'okwu ndị dị oke njọ, ọ ga-eme ka a kpochapụ akara zoro ezo ma ọ bụ mebie ngwá ọrụ ntụgharị na ihe ize ndụ ndị ọzọ, nke a bụ nsogbu nkịtị na mmepụta. N'ebe a, isiokwu a na-enyocha nkenke ihe mere e ji guzobe profaịlụ aluminum shrinkage na ụzọ isi kpochapụ ya.
Isi 2: Nhazi nke shrinkage na profaịlụ aluminom extruded site na extruders: mbelata oghere na mbelata afọ:
1) Mbelata nke oghere: A na-emepụta oghere n'etiti etiti ọdụ nke profaịlụ extruded na mmanya. Akụkụ obe na-egosi dị ka oghere nwere akụkụ siri ike ma ọ bụ oghere nwere akụkụ jupụtara na adịghị ọcha ndị ọzọ. The longitudinal direction bụ cone yiri olulu, n'ọnụ olulu ahụ chere ihu n'ụzọ nke ígwè eruba. Ọ tumadi eme na otu oghere ụgbọelu anwụ extrusion, karịsịa na ọdụ nke profaịlụ extruded na obere extrusion ọnụọgụ, nnukwu ngwaahịa diameters, oké mgbidi, ma ọ bụ mmanụ-ntọọ extrusion gaskets.
2) Mbelata nke afọ: The abụọ nsọtụ nke extrusion shunt kpụrụ ngwaahịa, karịsịa isi, bụ discontinuous yiri mgbaaka ma ọ bụ arcs, na crescent udi bụ ihe doro anya na abụọ nke ịgbado ọkụ akara. Mbelata afọ nke ngwaahịa oghere ọ bụla bụ ihe atụ.
Ihe mere e ji guzobe shrinkage: The n'ibu ọnọdụ n'ihi na e guzobere shrinkage bụ na mgbe advection ogbo agwụ na extrusion gasket ji nwayọọ nwayọọ na-abịaru nso na-anwụ anwụ, extrusion na-abawanye na site a nrụgide dN n'akụkụ elu nke extrusion gbọmgbọm. Nke a ike ya na esemokwu ike dT cylinder, mgbe ike itule ọnọdụ dN cylinder ≥ dT pad mebiri emebi, metal dị n'akụkụ extruded gasket ebe aga azụ azụ tinyere nsọtụ n'ime etiti nke oghere, na-akpụ a shrinkage.
Isi nke 3: Gịnị bụ ọnọdụ extrusion na-ebute mbelata na extruder:
1. Extrusion ihe fọdụrụnụ na-ahapụ oke mkpụmkpụ
2. The extrusion gasket bụ mmanu mmanu ma ọ bụ unyi
3. Elu nke ingot ma ọ bụ ajị anụ adịghị ọcha
4. Ogologo nkwụsị nke ngwaahịa anaghị agbaso ụkpụrụ
5. Ihe mkpuchi nke extrusion cylinder enweghị ndidi
6. The extrusion ọsọ na mberede na-abawanye.
Isi 4: Ụzọ iji kpochapụ shrinkage kpụrụ site na igwe extrusion aluminum na usoro iji belata ma gbochie nguzobe nke shrinkage:
1. Kpachara anya na-agbaso ụkpụrụ usoro iji belata ma pịa ihe ndị dị na ya, hụ isi na ọdụ, na-eme ka mkpuchi nke cylinder extrusion na-emebi emebi, machibido gas extrusion mmanụ, belata okpomọkụ nke mkpanaka aluminum tupu extrusion, ma jiri convex gaskets pụrụ iche. Họrọ ogologo ezi uche nke ihe fọdụrụnụ.
2. Elu nke ngwá ọrụ extrusion na aluminom mkpara kwesịrị ịdị ọcha
3. Na-elele ugboro ugboro size nke extrusion cylinder ma dochie erughị eru ngwaọrụ
4. Ntugharị dị nro, a ga-eme ka ọsọ ọsọ na-agba ọsọ na njedebe ikpeazụ nke extrusion, na ọkpụkpụ fọdụrụnụ kwesịrị ịhapụ nke ọma, ma ọ bụ usoro extrusion nke ịba ụba ihe fọdụrụnụ kwesịrị iji.
Isi 5: Iji kpochapụ ihe na-eme ka ọ dị irè n'oge mmepụta nke ígwè ọrụ mmepụta ihe nke aluminom, ọ dị mkpa ka a ṅaa ntị na oke ọkpụrụkpụ nke extruder. Nke a bụ ụkpụrụ ntụaka maka oke ọkpụrụkpụ:
