Description
Technical field
The present invention relates to a kind of aluminum pot and manufacture method thereof with the compound end.
Background technology
At present, various aluminum pot structures are numerous.General die casting aluminum pot can not use on electromagnetic stove.Be head it off, Chinese patent has just proposed " at the bottom of a kind of compound pot of aluminium matter pot and processing method " for No. 200510061988.3.In this technical scheme, the bottom of a pan of aluminum pot is fixed with magnetic conductive metal sheet, it is a plurality of projections of moulding in advance in the bottom of a pan earlier, a plurality of hole flangings that match with projection are routed up in the surperficial punching press of magnetic conductive metal sheet, hole flanging with magnetic conductive metal sheet is fastened on the projection in the bottom of a pan again, with the method for punching press the projection punching press is out of shape at last, magnetic conductive metal sheet is fixed on the bottom of a pan.The aluminum pot at the above-mentioned compound end can use at electromagnetic stove.But have the following disadvantages:
1, owing to only by projection punching press distortion magnetic conductive metal sheet is fixed on the bottom of a pan between above-mentioned magnetic conductive metal sheet and the bottom of a pan, and the operation of compounded magnetic conductive metallic plate carries out at normal temperatures, makes to contact not closely between magnetic conductive metal sheet and the bottom of a pan, and heat conductivility is undesirable.
2, owing to only fix between the above-mentioned magnetic conductive metal sheet and the bottom of a pan by the projection that is out of shape through punching press, magnetic conductive metal sheet is different with the thermal coefficient of expansion of aluminium, the projection of the bottom of a pan periphery in the process of expanding with heat and contract with cold by the magnetic conductive metal sheet pull-up, cause the projection periphery to upwarp, and then in use scratch electromagnetic stove.Even cause whole magnetic conductive metal sheet to come off from the pot body.
And for example, Chinese patent also discloses a kind of " composite bottom aluminum pot " for No. 200520102395.2, and in this technical scheme, composite bottom aluminum pot comprises pot body and the bag egative film that combines with its bottom, and the bag egative film is provided with several grooves, and the side of groove has through hole.It can prevent that aluminum pot from using the back to produce for a long time and taking off end phenomenon.But have the following disadvantages: because above-mentioned composite bottom aluminum pot has through hole in the side of groove, after the bag egative film and the bottom of a pan were compound, the upper edge of bag egative film through hole did not have aluminium alloy and coats, and in use, this edge meeting perk scratches electromagnetic stove.
Summary of the invention
The objective of the invention is to: provide be connected between a kind of compound end and aluminum pot reliable, heat conductivility is desirable, the aluminum pot with the compound end that can not scratch electromagnetic stove.
Another object of the present invention is: a kind of manufacture method of making aforementioned aluminum pot with the compound end is provided.
For reaching above purpose, the present invention is achieved through the following technical solutions:
A kind of aluminum pot with the compound end, the bottom of a pan is fixed with the metal magnetic conducting sheet, it is characterized in that: described metal magnetic conducting sheet is provided with plurality of opening and groove, bottom portion of groove is located in described perforate, groove is communicated with at least two perforates, the bottom of a pan and metal magnetic conducting sheet are cast into one by die casting machine, and in groove the filling aluminum alloy, the aluminium alloy in the groove is connected by the aluminium alloy in the perforate and the bottom of a pan.
The invention has the advantages that: because filling aluminum alloy in the groove, the aluminium alloy in the groove is connected by the aluminium alloy in the perforate and the bottom of a pan, makes between the metal magnetic conducting sheet of aluminum pot of the present invention and the bottom of a pan reliably fixing.Because the bottom of a pan and metal magnetic conducting sheet are cast into one by die casting machine, make contact between magnetic conductive metal piece and the bottom of a pan tight, the heat conductivility ideal.Because perforate is located at bottom portion of groove, groove is communicated with at least two perforates, makes the periphery of metal magnetic conducting sheet perforate all have aluminium alloy to coat, and in use, metal magnetic conducting sheet perforate periphery can perk, can effectively prevent to scratch electromagnetic stove.
In the present invention, described metal magnetic conducting sheet periphery crimping goes out the flange of perk, and the lateral surface of flange is coated by aluminium alloy.It can make the metal magnetic conducting sheet and the bottom of a pan fit closely, in conjunction with more firm, and improves heat conductivility.Simultaneously, metal magnetic conducting sheet periphery in use can perk, can effectively prevent to scratch electromagnetic stove.
In the present invention, described metal magnetic conducting sheet is whole or piecemeal.The metal magnetic conducting sheet of integral body or piecemeal all can be realized goal of the invention.
In the present invention, the described the bottom of a pan is provided with the pattern that the aluminium alloy by metal magnetic conducting sheet part outer surface, groove and the bottom of a pan constitutes.It can make the bottom of a pan more attractive in appearance.
In the present invention, a kind of or its combination of the described metal magnetic conducting sheet alloy sheet that is stainless iron plate, iron plate, iron content.
A kind of manufacture method of the aluminum pot with the compound end, it is characterized in that: manufacture method may further comprise the steps:
Make the metal magnetic conducting sheet, punching press forms perforate and groove on the metal magnetic conducting sheet, and bottom portion of groove is located in perforate, and groove is communicated with at least two perforates,
The metal magnetic conducting sheet is put into compression mod cover half die cavity;
Behind the die casting machine matched moulds, the liquid aluminium alloy of molten condition is inserted die cavity, pot body and above-mentioned metal magnetic conducting sheet are one by the die casting machine die cast;
After treating the compression casting pan cooling, carry out surface treatment again, can make aluminum pot with the compound end.
Adopt said method can be implemented in filling aluminum alloy in the groove easily, make contact closely between metal magnetic conducting sheet and the bottom of a pan of aluminum pot of the present invention, fixing reliably, heat conductivility is desirable.Because perforate is located at bottom portion of groove, groove is communicated with at least two perforates, makes the periphery of metal magnetic conducting sheet perforate all have aluminium alloy to coat, and in use, metal magnetic conducting sheet perforate periphery can perk, can effectively prevent to scratch electromagnetic stove.
In the present invention, before the metal magnetic conducting sheet was put into compression mod cover half die cavity, earlier at metal magnetic conducting sheet rear portion stationary positioned ring, the metal magnetic conducting sheet was positioned in the compression mod die cavity by locating ring, after die casting is finished, locating ring is removed.Locating ring can effectively solve the orientation problem of metal magnetic conducting sheet in press casting procedure.When the liquid aluminium alloy of molten condition impacted the metal magnetic conducting sheet, locating ring can guarantee that the metal magnetic conduction sheet does not depart from desired location, thereby guaranteed the quality of aluminum pot.
In the present invention, when the stationary positioned ring of metal magnetic conducting sheet rear portion, metal magnetic conducting sheet and locating ring are fixed with high-temperature agglomerant.Adopt high-temperature agglomerant can realize the fixing of locating ring and metal magnetic conducting sheet easily.
