Aluminum alloy deep-drawing multifunctional cup and machining technology thereof

Abstract

The invention relates to an aluminum alloy deep-drawing multifunctional cup and a machining technology thereof. The machining technology comprises the following steps of S1, aluminum material blanking; S2, primary cup forming; S3, primary stretching; S4, secondary stretching; S5, tertiary stretching; S6, quartus stretching; S7, quinary stretching; S8, trimming; S9, edge rolling of an opening part; S10, cleaning; S11, drying; and 12, packaging. According to the aluminum alloy deep-drawing multifunctional cup and the machining technology thereof, in the step S2, the width of a cup rim reserved aluminum material is compared with the reserved standard width of a cup rim through a central control module, the standard diameter size of a circular material sheet sheared in the step S1 is adjusted, in the step S3, the thickness of the stretched step part is compared with the standard step thickness through the central control module, the stretching speed of a primary stretching die part is adjusted, the central control module judges the thickness uniformity degree of the stretched step according to thickness difference values of all detection points, and adjustment is repeated in the steps S4, S5, S6 and S7.

Description

technical field [0001] The invention relates to the technical field of production and processing of aluminum cups, in particular to an aluminum alloy deep-drawing multifunctional cup and a processing technology thereof. Background technique [0002] Disposable paper cups on the market are disposable products, which violate the requirements of the new concept and development trend of reducing environmental pollution and promoting green recycling of materials, and the quality is uneven, causing great safety hazards. [0003] In order to achieve the water-proof effect of paper cups, a layer of polyethylene water-proof film will be coated on the inner wall during production. Polyethylene is the safest chemical substance in food processing. Polyethylene may be oxidized to carbonyl compounds in the process of heat-melting or applying to paper cups, and carbonyl compounds are not easy to volatilize at room temperature, but they may volatilize when the paper cups are poured with hot ...
