Description

At the bottom of a kind of compound pot of aluminium matter pot

Technical field

The utility model relates to the technical field of tableware pot, relates 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 protruding being equipped with, and be 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.The patent No. is that 2005201020259.1 Chinese patent " at the bottom of a kind of compound pot of aluminium matter pot " has been reported a kind of simple in structure, handling ease and steel plate is connected with the bottom of a pan at the bottom of the compound pot of more firm aluminium matter pot for this reason, it is smooth inadequately smooth that but a fly in the ointment is the compound bottom surface of bowl, and, because hole flanging and cold-stamped need, magnetic conducting and heating panel can not be done very thickly, influence the magnetic conducting and heating effect, this is the disadvantage defective that exists at the bottom of the traditional compound pot, requires further improvement design.

Summary of the invention

At the bottom of technical problem to be solved in the utility model is the compound pot of smooth attractive in appearance, aluminium matter pot that magnetic conducting and heating is effective at the bottom of a kind of simple and practical, handling ease being provided at above-mentioned prior art present situation and can making compound pot.

The utility model 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 aluminium matter pot bottom part compound fixing on magnetic conducting and heating panel, it is characterized in that forming a plurality of lug bosses in advance at described pot bottom part, magnetic conducting and heating panel is divided into top panel and the lower panel that links together, the hole flanging that a plurality of and described lug boss matches is routed up in the surperficial punching press of plate in the above, magnetic conducting and heating panel is fitted on the bottom in the aluminium matter the bottom of a pan, the hole flanging of top panel is fastened on the lug boss in the bottom of a pan, by extrusion modling, 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 cambered surface of flange bottom, and magnetic conducting and heating panel 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 magnetic conducting and heating panel 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.

Above-mentioned top panel and lower panel adopt spot welding or laser weld means to be welded together.

Described top panel and lower panel can be identical shaped and same sizes, are convenient to being welded to connect between them.

Further improve, the bottom of a pan molds shape and the adaptive shallow slot of thickness with top panel and lower panel in advance, make compound after, lower panel is smooth concordant with the bottom of a pan, makes at the bottom of the compound pot solid more attractive in appearance.

Can certainly be, described top panel and lower panel be identical shaped, and the size of lower panel is greater than top panel, the bottom of a pan molds shape and the adaptive shallow slot of upper and lower panel thickness with lower panel in advance, make compound after, lower panel is smooth concordant with the bottom of a pan, also can reach aforesaid effect basically.

At last, after the distortion of described lug boss also with lower panel in surperficial tensioner, thereby tightly be connected with pot bottom part.

Compared with prior art, advantage of the present utility model is: the magnetic conducting and heating panel that adopts top panel and lower panel to be formed by connecting, be compounded on the bottom surface of bowl, make at the bottom of the compound pot smooth attractive in appearance, and, increased lower panel, increased pyrotoxin, lower panel can adopt the thicker magnetic conducting and heating panel of thickness, improved the magnetic conducting and heating effect greatly, the lug boss in the bottom of a pan distortion in extrusion process, make the lug boss face deformation be coated on the arcwall face of flange bottom and lower panel on the surface, so magnetic conducting and heating panel 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 in the arcwall face of lug boss and the flange bottom on the bottom of a pan and the lower panel coating between the surface and tensioner effect that magnetic conducting and heating panel is firmly combined and is fixed on the bottom of a pan, so connect more firm, flange on the top panel 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, also be fit to select thicker slightly top panel, overall structure is simple and practical, handling ease, the production efficiency height.
