Uthini umgangatho wesizwe wokunyamezela ubungakanani beendawo zokutofa ngemoto?

Umgangatho wesizwe wokunyamezela ubungakanani beengxenye ze-injection yemoto yi-GB / T 14486-2008 "Iinxalenye zePlastiki ezibunjiweyo zoNyamezelo".Lo mgangatho uchaza ukunyamezelwa komgangatho weendawo ezibunjiweyo zeplastiki, kwaye zilungele iindawo ezibunjiweyo zeplastiki ezitofwayo, zicinezelwe kwaye zitofwe.

Ngokomgangatho wesizwe, uluhlu lokunyamezela ubungakanani beendawo zokutofa iimoto zahlulwe ngokwamabakala A no-B.Iimfuno ezichanekileyo zeKlasi A ziphezulu, zilungele iindawo zokutofa ezichanekileyo;Iimfuno zeBanga B ezichanekileyo ziphantsi, zilungele iindawo zokutofa ngokubanzi.Uluhlu oluthile lonyamezelo luloluhlobo lulandelayo:

(1) Unyamezelo lomda:
Imilinganiselo yomgca ibhekisa kwimilinganiselo ngobude.Kwiklasi A iinxalenye ezibunjiweyo zenaliti, uluhlu lonyamezelo lobungakanani bomgca ± 0.1% ukuya ku-± 0.2%;Kwiindawo ezibunjiweyo zenaliti yeKlasi B, uluhlu lonyamezelo lwemilinganiselo yomgca yi-±0.2% ukuya ku-±0.3%.

(2) Ukunyamezela i-engile:
Ukunyamezela i-engile kubhekiselele ekuphambukeni kwe-Engile kwimilo kunye nokunyamezela indawo.Kwiindawo ezibunjiweyo zeKlasi A, i-Angle tolerance yi-± 0.2 ° ukuya ku-± 0.3 °;Kwiindawo ezibunjiweyo zesitofu seKlasi B, ukunyamezela kwe-Angle yi-±0.3 ° ukuya ku-±0.5 °.

(3) Ukunyamezela imo kunye nesikhundla:
Ukunyamezelwa kwefom kunye nesikhundla kubandakanya ukujikeleza, i-cylindricity, i-parallelism, i-verticality, njl. Kwiklasi ye-injection yeklasi A, ifom kunye nokunyamezela kwesikhundla kunikwa ngokweklasi K kwi-GB / T 1184-1996 "Ukunyamezelwa kweMilo kunye neSimo esingachazwanga Ixabiso lokunyamezela";Kwicandelo le-injection yeklasi B, ifom kunye nokunyamezela isikhundla kunikwa ngokweklasi M kwi-GB / T 1184-1996.

(4) Uburhabaxa bomphezulu:
Uburhabaxa bomphezulu bubhekisa kwiqondo lokungalingani kwemicroscopic kumphezulu womatshini.Kwiklasi A iindawo ezibunjiweyo zesitofu, uburhabaxa bomphezulu yiRa≤0.8μm;Kwiindawo ezibunjiweyo zenaliti yeklasi B, uburhabaxa bomphezulu yiRa≤1.2μm.

Ukongeza, kwezinye iimfuno ezikhethekileyo zamalungu enaliti yemoto, njengeepaneli zesixhobo, i-console yeziko, njl.njl., iimfuno zonyamezelo ezinobungakanani zinokuba phezulu, kwaye kufuneka zilawulwe ngokweemfuno ezithile zemveliso.

Ngamafutshane, umgangatho wesizwe wonyamezelo olunobungakanani bendawo yokutofa iimoto yi-GB/T 14486-2008 “Unyamezelo lweDimensional of Plastic molded parts”, echaza iimfuno zonyamezelo olubanzi, imilo kunye nokunyamezelana kwesikhundla kunye noburhabaxa bomphezulu beplastiki ebunjiweyo. iinxalenye.Kwimveliso yokwenyani, kuyafuneka ukuba uhlengahlengiso kwaye ulungelelaniswe ngokweemfuno zemveliso kunye noyilo lokungunda ukuqinisekisa ukuba iinxalenye zenaliti yemoto ziyahlangabezana neemfuno.
