Description
Technical field
The present invention relates to the technical field of tableware pot, relate in particular at the bottom of a kind of compound pot of aluminium matter pot.
Background technology
Because aluminium is non-magnet material, therefore traditional aluminium matter pot is not suitable for using on electromagnetic stove, occurred at above-mentioned present situation market at the bottom of a kind of compound pot of aluminium matter pot, it is a kind of to be to be in compound last layer stainless steel bottom surface, original aluminium matter the bottom of a pan with it, and the bottom surface and the bottom of a pan are welded, and its defective is the processing technology complexity, steel plate need be welded on the bottom of aluminium matter pot, welding needs special equipment, is easy to have influence on the fineness on surface, the bottom of a pan simultaneously, and the cost of welding is also higher.Be that the Chinese utility model patent " at the bottom of the compound pot of aluminium matter pot " of ZL02217063.4 (notification number is CN2544654Y) has disclosed a kind of such structure also just like a patent No., it is at the compound upper steel plate in the bottom in the aluminium matter the bottom of a pan, it is characterized in that stamping out a plurality of hole flangings on the surface of steel plate, cold extrusion is carried out in the bottom that steel plate is fitted in the aluminium matter the bottom of a pan, make in the hole flanging that is squeezed into after the aluminum metal distortion in the aluminium matter the bottom of a pan on the steel plate, the flange of hole flanging is pressed in the aluminum substrate in the aluminum pot the bottom of a pan simultaneously, tightly embrace with aluminum substrate, steel plate is composite and fixed on the bottom in the aluminium matter the bottom of a pan.It is simple to have processing at the bottom of this compound pot, cost is low, connect advantages such as more firm, but because it is that the bottom of a pan does not form the lug boss that matches with hole flanging in advance, it is directly will have the steel plate amassing of hole flanging to the aluminium matter the bottom of a pan by the cold-stamped mode, it only is because the side of hole flanging is inserted into the bottom of a pan, frictional force effect by the hole flanging side and the bottom of a pan is combined in the bottom of a pan, therefore the combination in the steel plate and the bottom of a pan also is not very firm, also has at the bottom of the compound pot of above-mentioned aluminium matter pot the bottom of a pan that can only thin steel plate be expressed to aluminium matter pot, otherwise, steel plate thickness is blocked up, make its flange be not easy to be inserted on the flat the bottom of a pan, so its application also have certain limitation.
Summary of the invention
Technical problem to be solved by this invention is a kind of simple in structure, handling ease to be provided at above-mentioned prior art present situation and steel plate is connected with the bottom of a pan at the bottom of the compound pot of more firm aluminium matter pot.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: at the bottom of a kind of compound pot of aluminium matter pot, its compound fixedly upper steel plate in bottom in the aluminium matter the bottom of a pan, it is characterized in that forming a plurality of lug bosses in advance at described pot bottom part, rout up the hole flanging that a plurality of and described lug boss matches in the surperficial punching press of steel plate, steel plate is fitted on the bottom in the aluminium matter the bottom of a pan, by cold extrusion, the hole flanging of steel plate is fastened on the lug boss in the bottom of a pan, the flange of hole flanging week side is inserted in the bottom in the bottom of a pan, and the lug boss distortion is coated on the arcwall face of flange bottom, and steel plate is composite and fixed on the bottom of aluminium matter pot.
Above-mentioned lug boss is to be cylindric for good, described hole flanging is that to be the circular hole that matches with columnar projections portion be good, because the cooperation between columnar projections portion and the circular hole can make the contact-making surface between them maximum under kindred circumstances, its cross section of certain above-mentioned lug boss also can be square or triangle or other various present situations, and the shape of hole flanging is as long as match with it.
Above-mentioned lug boss evenly distributes in the form of a ring, the ring-type that described hole flanging also is evenly distributes, adopt this distribution can make the more attractive in appearance of the bottom of a pan change, and can also strengthen steel plate is evenly distributed with the power that is connected in the bottom of a pan, to improve the firm degree of combination, certainly it also can be flower-shaped distribution, perhaps is other radial mode and distributes.
Its periphery edge of above-mentioned steel plate is that the tight fit tensioner is connected with the pot bottom part cavity, with the be connected strength of further raising steel plate with the bottom of a pan, makes it be not easy to come off.
Compared with prior art, the invention has the advantages that: processing technology is simple, cost is low, does not need welding equipment, only needs just the steel plate and the bottom of a pan to be connected and fixed the production efficiency height once with punching press or extrusion equipment punching press; Because it not only is inserted into the bottom of a pan with the flange on the hole flanging, and the lug boss in the bottom of a pan is out of shape in extrusion process, the lug boss face deformation is coated on the arcwall face of flange bottom, so steel plate not only utilizes the frictional force effect in the hole flanging side and the bottom of a pan to be combined in the bottom of a pan, it also utilizes the coating effect of the arcwall face of lug boss bottom flange on the bottom of a pan that steel plate is firmly combined and is fixed on the bottom of a pan, so have and be connected firmly, flange on the steel plate forms the position-limiting action of lug boss in advance owing to the bottom of a pan when being inserted into the bottom of a pan, so thicker a little flange also can be more prone to be inserted into the bottom of a pan of lug boss, so it can select thicker slightly steel plate.
