Compound pot bottom of aluminum pot and manufacturing method thereof

Abstract

The invention provides a compound pot bottom of an aluminum pot, which comprises a magnetic conduction metal plate compounded on the bottom surface of the aluminum pot bottom, wherein an aluminum plate is combined by high temperature and high pressure on the surface of the magnetic conduction metal plate correspondingly combined with the aluminum pot bottom; a plurality of concentric circular convex parts and concave parts are arranged on the upper surface of the aluminum plate at intervals by using the center of the upper surface of the aluminum plate as the center of a circle; and the aluminum on the bottom surface of the aluminum pot bottom is combined with the concave parts by die-casting. The compound pot bottom of the aluminum pot has tight and firm connection, large contact area, good heat conduction effect and low cost, and has certain economical value and industrial value. The invention also provides a manufacturing method of the compound pot bottom.

Description

technical field [0001] The invention relates to the technical field of a tableware pot, in particular to a composite pot bottom of an aluminum pot. Background technique [0002] Because aluminum is a non-magnetic material, traditional aluminum pans are not suitable for use on induction cookers. Aiming at the above-mentioned current situation, a composite pan bottom of aluminum pans has appeared in the market, which is a layer of magnetic conductivity on the aluminum pan bottom. The metal bottom surface is welded to the bottom of the pot. The disadvantages are: the processing technology is complicated, and the steel plate needs to be welded to the bottom of the aluminum pot. The welding requires special equipment, and it is easy to affect the smoothness of the bottom surface of the pot, and the cost is also high. higher. There is also a composite pot bottom of an aluminum pot with such a structure that a steel plate is laminated on the bottom of the aluminum pot bottom, whic...

[0002] Because aluminum is a non-magnetic material, traditional aluminum pans are not suitable for use on induction cookers. Aiming at the above-mentioned current situation, a composite pan bottom of aluminum pans has appeared in the market, which is a layer of magnetic conductivity on the aluminum pan bottom. The metal bottom surface is welded to the bottom of the pot. The disadvantages are: the processing technology is complicated, and the steel plate needs to be welded to the bottom of the aluminum pot. The welding requires special equipment, and it is easy to affect the smoothness of the bottom surface of the pot, and the cost is also high. higher

But it has the following defects: ①The bottom is uneven and not smooth, and it is easy to scratch the surface of the stove; ②Because the bottom of the pot is not pre-formed with a raised part that matches the turning hole, and the pot with the turning hole is directly formed by aluminum die-casting. The steel plate is extruded to the bottom of the aluminum pot. It is only because the side of the hole is inserted into the bottom of the pot, and at the same time, it is combined with the bottom of the aluminum pot through the friction between the side of the hole and the bottom of the pot. Therefore, the steel plate and the aluminum The combination of the bottom of the pot is not firm; ③The processing technology is more complicated, and a press (cold press) or friction press with a higher pressure is required; ④For a pot with a relatively small bottom area, such a composite structure is adopted, and the steel plate is Or ring-shaped and other factors cause its area to be greatly reduced, reduce the effect of magnetic conduction and heat generation, and prolong the heating time; Its flipped edges are not easy to insert into flat pan bottoms
