Flat plate full double-bottom aluminium pot

Abstract

The invention discloses a flat plate full double-bottom aluminium pot. The pot comprises a pot body, the pot body is in stretching, pressure casting or extrusion forming, and a horizontal pot bottom surface is formed at the bottom of the pot body; a two-sided flanging hole magnetic conductive metal plate covers the bottom surface of the pot body, several heat conducting holes are formed in the two-sided flanging hole magnetic conductive metal plate, several rings of upper flanging holes facing upward are formed in the surface with the heat conducting holes, and several rings of lower flangingholes facing downward are formed in the other surface of the metal plate. When the metal plate is combined with the pressure casting pot body, protruding aluminum posts used for riveting are formed onthe bottom surface of the pressure casting pot body, the quantity of the aluminum posts is same with that of the heat conducting holes in one surface of the magnetic conductive metal plate, each aluminum post is right opposite to and penetrates through one heat conducting hole, and a double-layer composite bottom piece further covers the bottom of the two-sided flanging hole magnetic conductive metal plate and is integrally in press fit with the two-sided flanging hole magnetic conductive metal plate on a large-tonnage hydraulic machine through cold pressing forming.

Description

technical field [0001] The invention mainly relates to the technical field of pots, in particular to a flat aluminum pot with a full double bottom. Background technique [0002] Among these pots in the prior art, the traditional aluminum alloy pot cannot be used on the increasingly popular induction cooker due to its lack of magnetic conductivity, while the die-casting pot, extrusion pot, and stretching pot can be used on the induction cooker through the double-bottom technology. However, due to process defects in the production process of these pots, the thickness of the bottom of the aluminum pot is often insufficient, so that the products produced cannot meet the European 12983 standard (bottom stability standard). In addition, because the existing die-casting pots, extrusion pots, and stretching pots generally use the full-covering production technology, this technology is currently limited to the production of large-tonnage friction presses using the heat-covering proce...

Problems solved by technology

[0002] Among these pots in the prior art, the traditional aluminum alloy pot cannot be used on the increasingly popular induction cooker due to its lack of magnetic conductivity, while the die-casting pot, extrusion pot, and stretching pot can be used on the induction cooker through the double-bottom technology. However, due to process defects in the production process of these pots, the thickness of the bottom of the aluminum pot is often insufficient, so that the products produced cannot meet the European 12983 standard (bottom stability standard)

In addition, because the existing die-casting pots, extrusion pots, and stretching pots generally use the full-covering production technology, this technology is currently limited to the production of large-tonnage friction presses using the heat-covering process, and the production equipment requires an investment of 2 million yuan. The thermal cladding production process needs to heat the product to about 450 degrees. The production cost is high, the energy waste is high, and there are safety hazards during production and processing.

From a manufacturing point of view, many factories now use large-tonnage friction presses, electric screw presses, high-energy-consuming electric furnaces and other equipment to produce full-covered bottom products. The production noise is high, energy consumption is high, and resources are wasted seriously.
