Technical Performance, Processing Technology And Guarantee Measures Of Extrusion
1. Technical performance of extrusion
(1) Technical requirements for physical properties: 6063-T5,
(2) Yield strength: RP0.2≥160m㎡,
(3) Elongation: A10≥10%
2. Extrusion production process flow chart
Aluminum rod heating -- extrusion -- air cooling hardening -- straightening -- Sawing -- finishing -- framing -- manual aging -- hand over (rotation)
3. Extrusion production guarantee measures
(1) The extrusion team shall self-check the geometric size and surface quality, and the full-time quality inspector shall recheck the geometric size and surface quality;
(2) The cooling rate of air-cooled quenching is controlled by the team;
(3) The tensile alignment is controlled by the team;
(4) The cutting length of finished products is controlled by the team;
(5) The dimensional accuracy of finished products shall be controlled by the team and the quality inspector;
(6) Manual aging by the team control aging process, quality inspector control mechanical properties;
(7) Detection means: geometric size with micrometer, Angle ruler to measure, mechanical hardness tester, tensile testing machine, surface quality with sample, manual observation.
