Ni miringo ki ey’okukora ebicweka bya pulasitiki?
Ni miringo ki ey’okukora ebicweka bya pulasitiki?
Enkora y‘okukora ebicweka bya pulasitiki neekira kuba neekwata aha kuteekateeka nk‘okupima, okuhikiirira kw‘ebipimo, omubaro gw‘okuteera, obushaarizi bw‘ahaiguru, obuhango bw‘ekisiika, enkokora y‘okuteera, oburaingwa bw‘ekiina, radii ya fillet, enkokora y‘okuteera ekibumbe, n‘embaju z‘okuhamya. Ekicweka eki nikiija kushoboorora ahari buri nshonga egi kandi kigambire aha ku orikubaasa kutunguura ebintu ebi omu bwire bw‘okukora thermoforming kubaasa kutunguura omutindo gw‘ebintu n‘okukora gye.
1. Geometry n’okuhikiirira kw’ebipimo
Kwiha okukora obuveera oburikwotsya ni omuringo gw’okukora ogwa kabiri, namunonga omu kuhanga omu mwanya ogutarimu kintu kyona, nihakira kubaho omwanya ahagati y’ekipande ky’epulasitiki n’ekibumbe. Okwongyera ahari ekyo, okukyendeera n’okuhinduka, namunonga omu myanya erikurugayo, nikibaasa kureetera obuhango bw’ebisiika kukyendeera, ekirikureetaho okukyendeera omu maani. Nahabwekyo, ebicweka bya pulasitiki ebirikukoresibwa omu kuhanga ebintu omu mwanya ogutarimu kintu kyona tibiine kuba biine ebirikwetengyesa ebigumire munonga aha bikwatiraine n’okupima n’okuhikiirira kw’okupima.
Omu bwire bw’okukora, orubaaho rw’ekiveera orurikwotsya ruri omu mbeera y’okutambatambura etaine nshonga, ekirikubaasa kureetera okugwa. Okwegaita aha kukyendeeza kw‘amaani n‘okukyendeera bwanyima y‘okusheenya, ebipimo by‘aha muheru n‘ekishushani ky‘ekintu nibibaasa kuba bitagumire ahabw‘empindahinduka z‘obutagatsi n‘eby‘obuhangwa. Ahabw’enshonga egi, ebicweka bya pulasitiki ebikozirwe omu muringo gw’okwotsya tibirikubaasa kukoresibwa omu kubumba ebintu omu muringo oguhikire.
2. Omubaro gw'okuteera
Omubaro gw’okuteera, oguri omubaro gw’oburaingwa bw’ekicweka (nari oburaingwa) n’obugazi bwakyo (nari shi oburaingwa bwakyo), nigwo gurikumanyisa munonga oburemeezi bw’omuringo gw’okukora. Oku omubaro gw‘okuteera gurikweyongyera, nikwo n‘omuringo gw‘okubumba gurikweyongyera kuguma, kandi nikwo n‘enshonga ezitarikwetengyesa nk‘okunyiganyiga nari okusharara zirikweyongyera. Ebipimo by‘okuteera ebirengire nibikyendeeza munonga amaani n‘okuguma kw‘ekicweka. Nahabwekyo, omukukora buzima, orurengo oruri ahansi y'omubaro gw'okuteeraho ogurikukirayo nirukoresibwa, obwire obwingi ahagati ya 0.5 na 1.
Omubaro gw‘okuteera nigukwatagana butunu n‘obuhango bw‘ekisiika obukye bw‘ekicweka. Omubaro gw‘okuteeraho mukye nigubaasa kureetaho ebisiika ebihango, ebihikire omu kuhanga ebipande ebikye, kandi omubaro gw‘okuteeraho muhango nigwetengyesa ebipande bikye munonga kureeba ngu obuhango bw‘ebisiika tibwahinduka bukye munonga. Okwongyera ahari ekyo, omubaro gw’okuteera nagwo nigukwatagana n’enkokora y’okuteera ekibumbe n’okubaasa kutambaara kw’ebintu by’obuveera. Okureeba ngu ebintu byaguma biri aha mutindo, omubaro gw‘okushohoza gushemerire kukyeberwa okwetantara okweyongyera kw‘omubaro gw‘ebintu ebisigaireho.
3. Okukora Fillet
Enshonda eziine obushaarizi tiziine kutebeekanisibwa aha nshonda nari aha rubaju rw’ebicweka by’ebiveera. Omu mwanya gw‘ekyo, fillet mpango nk‘oku kirikubaasika eshemerire kukoresibwa, kandi radius y‘enkoona okutwarira hamwe etari nkye kukira emirundi 4 kuhika ahari 5 y‘obuhango bw‘orupapura. Okuremwa kukora ekyo nikibaasa kureetera ebintu kukyeera n‘okuta omutima aha nshonga, ekirikukwata kubi aha maani g‘ekicweka n‘okugumaho kwakyo.
4. Enkokora y'okuhandiika
Okukora eby'okwotsya ebibumbe, ebirikushushana n’ebibumbe ebya buriijo, nibyetenga enkokora y’okuteeraho emwe kubaasa kuhwera omu kusheenya ebibumbe. Enkokora y’okuteeraho neeruga ahari 1° kuhika ahari 4°. Enkokora nkye y‘okuteera ebibumbe neebaasa kukoresibwa aha bibumbe by‘abakazi, nk‘oku okukyendeera kw‘ekicweka ky‘ekiveera kurikuha omwanya ogundi ogw‘okwongyeramu, ekirikureetera okubinga ebibumbe byanguha.
5. Okuhamya Rib Design
Ebipande by’ebiveera ebikozirwe omu muringo gw’okwotsya nibikira kuba bikye munonga, kandi omuringo gw’okubikora nigukye ahabw’omubaro gw’okuteera. Nahabwekyo, okwongyera aha mbaju z‘okuhamya omu myanya erimu amaani makye omu nkora n‘omuringo mukuru gw‘okwongyera aha kuhama n‘amaani. Okuteebwaho kw‘embaju z‘okuhamya kushemerire kuteekateekwaho gye okwetantara emyanya erikukyeera munonga ahansi n‘omu nshonda z‘ekicweka.
Okwongyera ahari ekyo, okwongyeraho ebifunjo ebitari bihango, ebishushani, nari obubonero ahansi y’ekibunu ekikozirwe omu muringo gw’okwotsya nikibaasa kwongyera aha kuhama n’okuhagira omubumbi. Emigyera etari y’oburaingwa aha mbaju neeyongyera aha kuhama kw’okutegyeka, kandi emigyera etari y’ahaiguru ey’okuraba, n’obu eraabe neeyongyera aha kugumisiriza okugwa, neebaasa kureetera okusheenya kuguma.
6. Okukyendeera kw’ebintu
Ebintu ebikozirwe omu muringo gw'okwotsya okutwarira hamwe nibatunga okukyendeera kw‘amaani, n‘ebicweka nka 50 ahari igana ebirikubaho omu bwire bw‘okukyendeeza omu kicupuri. Ebiriisa by‘ekibumbe byaba biri ahaiguru, ekicweka nikibaasa kukyendeera n‘ebicweka 25% ebindi nk‘oku kirikukyendeera kuhika aha biriisa by‘omu kishengye bwanyima y‘okusheenya, n‘ebicweka 25% ebisigaireho eby‘okukyendeera nibibaho omu shaaha 24 ezirikukurataho. Ekindi, ebintu ebikozirwe barikukoresa ebibumbe by’abakazi nibikira kugira omubaro gw’okukyendeera 25% kuhika 50% kukira ebyakozirwe n’ebibumbe by’abashaija. Nahabwekyo, ni kikuru munonga kuteekateeka aha kukyendeera omu bwire bw‘okukora enteekateeka kureeba ngu ebipimo by‘aha muheru byahikiiriza ebyetaago by‘okuhikiirira.
Omu kutunguura enkora ya geometry, omubaro gw’okuteera, radius ya fillet, enkokora y’okuteera, embaju z’okuhamya, n’okukyendeeza, omutindo n’okuhama kw’ebicweka by’obuveera ebikozirwe omu muringo gw’okwotsya nibibaasa kutunguuka munonga. Ebintu ebi eby‘okukora enkora biine akakwate kakuru n‘okukora gye n‘okukora gye kw‘ebintu ebikozirwe omu muringo gw‘okwotsya kandi n‘ekikuru omu kureeba ngu ebintu byahikiiriza ebyetaago by‘abarikubikozesa.
