Description
Technical field
The present invention relates to a kind of preparation method of aluminium pot with metal magnetic conducting and heating panel covered on bottom.
Background technology
Because of aluminum pot can not use on electromagnetic oven, must just can use at its covered on bottom one deck ferrite metal.The mode that adopts has two big classes at present.
One class is the hot weld double-pressure type; Be about to aluminum pot and ferrite metal (being the metal magnetic conducting piece) and heat simultaneously,, by the intermediate frequency welding manner two kinds of materials are welded again, push through large tonnage pressing machine again, finish whole process flow then in its composition surface coated with adhesive.This type of advantage through technological method for processing is; Surfacing, attractive in appearance, bottom are integral planar, and its magnetic conductivity is good, thermal efficiency height.Its shortcoming is; The processing technology complexity, energy consumption height in the process, production cost is also high.
One class is a cold xtrusion; The ferrite metal is processed into cellular, this Kong Bingxiang outer lug, when topped, only need with the ferrite metal aperture to outer lug one facing to the aluminum pot bottom, by forcing press the part of projection is squeezed into the aluminum pot bottom then, make the ferrite metal cling the aluminum pot bottom firmly, reach the purpose of its combination.Its advantage is; Processing technology is simple, and energy consumption is low in the process, and production cost is also low.Its shortcoming is; Porose because of its bottom, effective area is little, and magnetic property is poor, uses the energy consumption height.
Existing a kind of application number has proposed a kind of structure for the Chinese invention patent that the CN200710026471.X name is called " making method of composite-bottom steel-aluminum pot and products thereof ", and its structure is made steel-aluminum pot by steel-aluminum composite plate earlier, and inwall simultaneously is a steel disc; Superimposed superimposed with the aluminium flake in the bottom of a pan again with aluminium-magnetic conductive metal sheet, spot welding links into an integrated entity, and the high temperature heating is placed on the pressure welding of carrying out HTHP on the large-tonnage friction press, obtain steel-aluminium-four layers of compound composite-bottom steel-aluminum pot of aluminium-magnetic conductive metal, its base thickness is greater than the pot wall thickness.Thick 2～the 6mm of compound aluminium sheet; Magnetic conductive metal sheet is selected corrosion resistant plate for use, thick 0.5～0.8mm.The product that the production method of this invention is produced has improved security and safety in utilization to food, compoundly firmly conducts heat evenly, heats effectively, through anodized, has improved the case hardness of product.Be applicable to electromagnetic oven, on electric furnace and the common kitchen range.But its shortcoming is, technology is complicated, needs bloom as the inwall of aluminum pot, and magnetic conductive metal sheet is that the mode of logical spot welding is combined with each other with the aluminum pot bottom, and its flatness reaches firmly all undesirable.So its structure awaits to improve.
Summary of the invention
Technical problem to be solved by this invention be provide at above-mentioned prior art present situation that a kind of technology is simple, the preparation method of a kind of aluminium pot with metal magnetic conducting and heating panel covered on bottom that aluminum pot and the compound bottom of metal magnetic conducting piece are smooth.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: the preparation method of this bottom aluminium pot with metal magnetic conducting and heating panel covered, it is characterized in that: described metal magnetic conducting and heating panel divides top plate and lower plywood, the upper and lower surface of lower plywood is designed to the plane, and top plate is processed into cavernous porous plate, Kong Bianzhong at the top plate upper surface routs up annular nib through punching press, the upper surface of the lower surface of top plate and lower plywood is stacked and be together with each other through welding, annular nib on the top plate is squeezed in the aluminum pot bottom by the cold-stamped mode with forcing press then, and metal magnetic conducting and heating panel is composite and fixed on the bottom of aluminum pot, promptly finish the whole technology of metal magnetic conducting piece on the aluminum pot covered on bottom.
As improvement, described annular nib can be preferably even distribution.
Improve, the mode of described welding by spot welding is preferably lower plywood and top plate is welded to each other together again.
Improve, described metal magnetic conducting and heating panel may be selected to be the stainless steel alloy plate of steel plate, iron plate or iron content again.
Improve, the convex annular on the described top plate even can be the overall structure that disposable casting forms with lower plywood again.
Improve, described top plate and lower plywood peripheral shape and thickness are same size again.
Compared with prior art, the present invention belongs to magnetic conducting and heating panel with gold mining and divides top plate and lower plywood, the upper and lower surface of lower plywood is designed to the plane, and top plate is processed into cavernous porous plate, Kong Bianzhong at the top plate upper surface routs up annular nib through punching press, the upper surface of the lower surface of top plate and lower plywood is stacked and be together with each other through welding, annular nib on the top plate is squeezed in the aluminum pot bottom by the cold-stamped mode with forcing press then, and metal magnetic conducting and heating panel is composite and fixed on the bottom of aluminum pot, promptly finish the whole technology of metal magnetic conducting piece on the aluminum pot covered on bottom.The advantage of this preparation method is: simplifying manufacture craft, simultaneously, keeping that magnetic property is good, the advantage smooth, attractive in appearance of compound bottom, promptly reducing the production cost of this aluminum pot effectively.
