Abstract

The utility model relates to the technical field of pots of the tableware. The utility model is an aluminum pot, which is designed to be used on an electromagnetic stove. The bottom part of the aluminum pot bottom is compounded with a steel plate; the utility model is characterized in that the surface of the steel plate is provided with a plurality of flanging holes by punch pressing, the steel plate is affixed with the bottom part of the aluminum pot bottom and is treated by cold extrusion, the aluminum metals at the aluminum pot bottom are intruded into the flanging holes which are arranged on the steel plate after deformation, at the same time, the turning sides of the flanging holes are pressed in an aluminum substrate of the aluminum pot bottom, so as to be clung with the aluminum substrate tightly, and the steel plate is compounded and fixed on the bottom part of the aluminum pot bottom. The utility model has the advantages of simple processing, low cost, firm connection and so on, which is applicable to the popularization and usage in the pots.

Description

At the bottom of the compound pot of aluminium matter pot

Technical field

The utility model relates to a kind of technical field of tableware pot.

Background technology

Traditional pot is as pressure cooker, frying pan, frying pan, pans such as non-stick pan adopt aluminum material to make more, because aluminum material is a non-magnet material, so this tableware can't use on electromagnetic stove, yet along with making constant progress of science and technology, new heating cooler such as electromagnetic stove enter into common common people family widely, and aluminium matter pan cannot use the competitiveness that certainly will limit on its market on the electromagnetic stove, pan at the bottom of scientific and technical personnel develop compound pot is arranged for this reason, as the patent No. is 96230065.9 Chinese patent " sticking composite bottom aluminum pot ", it is in compound one deck stainless steel bottom surface, original aluminium matter the bottom of a pan, the bottom surface and the bottom of a pan are welded, this bottom surface can make full use of the electrocaloric effect of electromagnetic stove, rapidly heat is transferred heat to the aluminium matter the bottom of a pan, thereby reach quick, easy clean, the good result of health.Its defective is the processing technology complexity, steel plate need be welded on the bottom of aluminium matter pot, and welding needs special equipment, is easy to have influence on the aesthetic property of pot smooth surface simultaneously, and production cost increases many.It as the patent No. 00228724.2 Chinese patent " aluminum pot with composite bottom ", comprise aluminium matter pot body, it is characterized in that being provided with one deck with at the bottom of the steel bag that aluminum pot pot body bottom surface face contacts in the external wall of aluminium matter pot bottom, because this aluminium matter pot body bottom surface coats at the bottom of one deck steel bag, so can improve the intensity in the bottom of a pan greatly, and this aluminum pot with composite bottom also can be used for electromagnetic oven.It has new technological progress than previous patented technology, does not need welding, and the surface is smoother also, but the bag end is to utilize HTHP to be stamped to form, so firmness is not ideal enough, particularly service time one is long, be easy to generate the bag end and the bottom of a pan break-off, influence is conducted heat and is used easily.

Summary of the invention

Technical problem to be solved in the utility model be at prior art a kind of handling ease be provided, increase that cost is few, at the bottom of the compound pot of the aluminium matter pot that is connected firmly.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: at the bottom of the compound pot of this kind aluminium matter pot, 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 routing up a plurality of hole flangings in the surperficial punching press 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, hole flanging limit on the steel plate is inserted in the aluminium matter the bottom of a pan simultaneously, tightly embrace with the bottom of a pan, steel plate is composite and fixed on the bottom in the aluminium matter the bottom of a pan.

Described hole flanging is connecting hole that connects or the connecting hole that does not connect.

Compared with prior art, advantage of the present utility model is: 1, processing technology is simple, cost is low, does not need welding equipment, the general manufacturer that produces pot has punching press or extrusion equipment, as long as punching press once just can be connected and fixed the steel plate and the bottom of a pan, the production efficiency height, fast; 2, be connected firmly, utilize aluminum metal to be out of shape in the hole flanging that is squeezed on the steel plate, the flange of hole flanging is pressed in the aluminum substrate simultaneously, tightly embraces with aluminum substrate, and they are coupled together securely, is connected firmly, and has grown the separation that also can not come off easily service time; 3, the bottom of a pan flat appearance is attractive in appearance, has improved the intensity in the bottom of a pan, and the protection the bottom of a pan makes the pot at the compound end use on electromagnetic stove simultaneously.

Description of drawings

The compound pot bottom structure cutaway view of Fig. 1 aluminium matter pot;

Fig. 2 is Fig. 1 partial enlarged drawing;

Upward view at the bottom of the compound pot of Fig. 3 aluminium matter pot.

The specific embodiment

Below in conjunction with description of drawings embodiment of the present utility model is described in further detail.

Embodiment 1, anticipate as Figure 1-3, at the bottom of the compound pot of this kind aluminium matter pot, it is at the bottom in the aluminium matter the bottom of a pan 1 compound upper steel plate 2, this steel plate 2 adopts circular stainless-steel sheet, so both attractive in appearance, be not easy again to get rusty, make being connected as far as possible firmly between the bottom of a pan and the steel plate simultaneously, the surface of steel plate stamps out a plurality of uniform hole flangings 3 and does connecting hole, and hole flanging is the annular arrangement that is concentric, make like this bottom of a pan and steel plate to be connected force distribution even, improve its aesthetic property simultaneously, adopt thin steel plate, its connecting hole can be the hole flanging that connects.Cold extrusion or punching press are carried out in the bottom 1 that then steel plate 2 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, and the flange of hole flanging is pressed in the aluminum substrate in the aluminum pot the bottom of a pan, tightly embrace with aluminum substrate, steel plate 2 is securely fixed on the bottom 1 in the aluminium matter the bottom of a pan.

Embodiment 2, at the bottom of the compound pot of this kind aluminium matter pot, it is at the bottom in the aluminium matter the bottom of a pan 1 compound upper steel plate 2, this steel plate 2 adopts circular stainless-steel sheet, so both attractive in appearance, be not easy again to get rusty, make being connected as far as possible firmly between the bottom of a pan and the steel plate simultaneously, the surface of steel plate 2 stamps out a plurality of uniform hole flangings 3 and does connecting hole, hole flanging is the annular arrangement that is concentric, make the bottom of a pan and steel plate to be connected force distribution even, improve its aesthetic property simultaneously, adopt thicker steel plate, its hole flanging can be the connecting hole that does not connect.Cold extrusion or punching press are carried out in the bottom 1 that the one side of steel plate 2 hole flangings is fitted in the aluminium matter the bottom of a pan then, make in the hole flanging 3 that is squeezed into after the aluminum metal distortion in the aluminium matter the bottom of a pan on the steel plate, and the flange of hole flanging is pressed in the aluminum substrate in the aluminum pot the bottom of a pan, tightly embrace with aluminum substrate, steel plate 2 is securely fixed on the bottom in the aluminium matter the bottom of a pan.
