Aluminium pot, composite bottom of aluminium pot and method for manufacturing composite bottom of aluminium pot

Abstract

The invention discloses a composite bottom of an aluminium pot, comprising a magnet-conducting metal plate. The magnet-conducting metal plate is compounded and connected with the bottom of the aluminium pot in pressing and fixing way and provided with a plurality of through holes. The invention further discloses the aluminium pot with the composite bottom and a method for manufacturing the composite bottom of the aluminium pot. The method comprises the following steps: (1) providing the magnet-conducting metal plate which matches with the bottom of the aluminium pot; (2) disposing a plurality of through holes on the magnet-conducting metal plate; and (3) connecting the magnet-conducting metal plate with the bottom of the aluminium pot in a pressing and fixing way by using a large-tonnage pressing machine. Because the magnet-conducting metal plate is provided with a plurality of through holes and connected with the bottom of the aluminium pot in a pressing and fixing way to realize the compounding of the bottom of the aluminium pot, the magnet-conducting metal plate and the bottom of the aluminium pot can be connected more firmly and smoothly, and the aluminium pot with the composite bottom is safer and more practical. The method for manufacturing the composite bottom of the aluminium pot is simpler and easier to operate and has low cost.

Description

technical field [0001] The invention relates to an aluminum pot composite bottom, an aluminum pot and a method for making the aluminum composite bottom. Background technique [0002] Because aluminum is a non-magnetic material, traditional aluminum pans are not suitable for use on induction cookers. In view of the above-mentioned current situation, a composite pan bottom of aluminum pans has appeared in the market, that is, a layer of magnetic conductive metal plate is laminated on the aluminum pan bottom. Specifically, these composite pot bottoms in the prior art can be roughly divided into two types according to the structure and the method of manufacture. One type is a magnetically conductive metal plate that is directly welded on the bottom of an aluminum pot, that is, it is welded to the bottom of the aluminum pot by welding. The magnetic conductive metal plate is composited on the bottom of the aluminum pot, and its disadvantages are: the process is complicated, and th...

[0002] Because aluminum is a non-magnetic material, traditional aluminum pans are not suitable for use on induction cookers. In view of the above-mentioned current situation, a composite pan bottom of aluminum pans has appeared in the market, that is, a layer of magnetic conductive metal plate is laminated on the aluminum pan bottom. Specifically, these composite pot bottoms in the prior art can be roughly divided into two types according to the structure and the method of manufacture. One type is a magnetically conductive metal plate that is directly welded on the bottom of an aluminum pot, that is, it is welded to the bottom of the aluminum pot by welding. The magnetic conductive metal plate is composited on the bottom of the aluminum pot, and its disadvantages are: the process is complicated, and the magnetic conductive metal plate needs to be welded on the bottom of the aluminum pot. The welding requires special equipment and professional technicians and is easy to affect the surface of the bottom of the pot. The flatness of the pan leads to problems such as the unsatisfactory heating effect of the bottom of the pan, and the cost is high; the other is to set the surface of the magnetic conductive metal plate for composite connection with the bottom of the aluminum pan to a structure with protrusions and grooves, and then The material at the bottom of the aluminum pot is deformed by extrusion and squeezed into the groove to form a composite connection between the two. The combination of the bottom of the pot is not reliable. Over time, the gap between the two is prone to water and moisture seepage, which will cause the double bottom to fall off, which will affect the thermal conductivity and safety of use.
