Abstract
The invention discloses a firmly connected electric heating pan composite bottom and a processing process thereof. The electric heating pan composite bottom comprises a pan body, wherein an aluminum disk is arranged at the bottom of the pan body; a heating pipe and a bracket for fixing the heating pipe are arranged on the aluminum disk; a network disk with the shape matched with that of the bottom of the pan body is arranged between the pan body and the aluminum disk; and the network disk divides the bottom of the pan body into a plurality of small regions. The network disk is fixedly connected with the pan body by a spot welding mode. The pan body and the aluminum disk are connected by a brazing mode. The network disk is arranged between the pan body and the aluminum disk, the surface of the pan body is divided into different small regions, and molten brazing filler metal only can flow in the small regions limited by the network disk during brazing, so that the fact that each region has the welding point is guaranteed, large-area regions without being connected by the brazing filler metal do not exist and the connecting strength of the pan body and the aluminum disk is improved.
Description
Technical field
The present invention relates to a kind of electric food warmer composite base, specifically a kind of electric food warmer composite base being connected firmly and processing
Technique.
Background technology
Electric food warmer is extensively applied by people as a kind of conventional electric-heating cooking utensil, and its structure generally comprises pot and bottom
Seat.With the development of electric food warmer technology, people have invented a kind of multiple bottom electric food warmer, and which welds the bottom of an aluminum in bottom of pot body
Disk, the chassis of aluminum serves energy-conservation, makes the effect that pot is heated evenly, and bottom electric food warmer progressively instead of commonly again at present
Electric food warmer.
But as pot is different with the material on chassis and traditional realizes, by melting fertile material, the weldering that welds
Technique is connect it is impossible to ensure that the outward appearance of pot, therefore typically adopts soldering processes during welding aluminium dish.
Soldering is to make solder using than the low-melting metal material of mother metal, by weldment and solder heat to melting higher than solder
Point, less than mother metal fusion temperature, using liquid solder moistening mother metal, fills play movement and realizes being connected with the counterdiffusion of mother metal phase
The method of weldment.Brazing deformation is little, joint smooth and beautiful appearance, is suitable for welding component that is accurate, complicated and being made up of different materials.
But as the general the bottom of a pan is all with certain radian, during soldering is carried out, pricker often occurs
Expect to melt backward surrounding flowing (when pot back-off is placed) or to the flowing of the bottom of a pan center (when pot forward direction is placed), so as to cause
Large-area no solder junction region domain.So that pot and aluminium dish is expanded when being heated, cooling down, systolic dyssynchrony, so as to cause aluminum
The coming off of disk, connects insecure, has a strong impact on the service life of electric food warmer.
Content of the invention
For the problems referred to above, the present invention passes through to arrange Dropbox between pot and aluminium dish, is effectively guaranteed aluminium dish and pot
Bonding strength between body, it is to avoid aluminium dish is come off from pot in use, extends the service life of electric food warmer.
The present invention solves its technical problem and is adopted the technical scheme that：
A kind of electric food warmer composite base being connected firmly, including pot, the bottom of the pot is provided with aluminium dish, described aluminum
Heating tube and the support for fixing the heating tube is provided with disk, is provided with and the pot between described pot and aluminium dish
The Dropbox that the shape of body bottom matches, the bottom of the pot is divided into multiple zonules by described Dropbox；
Described aluminium dish is fixedly connected by way of soldering between pot；
Several have been uniformly arranged in described Dropbox raised, described projection is embedded into the inside of the aluminium dish.
Further, described Dropbox is fixedly connected with described pot by way of spot welding.
Further, described projection is in cylindrical barrel structure.
Further,：Described Dropbox is made using stainless steel.
Further, described Dropbox is in spider reticulation structure.
Further, described Dropbox is in alveolate texture.
Further, described Dropbox is in lattice-shaped structure.
For processing a kind of processing technique of the electric food warmer composite base being connected firmly, comprise the following steps,
(1) Dropbox is welded on by way of spot welding bottom of pot body；
(2) on bottom of pot body or aluminium dish, uniform painting spreads solder；
(3) using press fit device, aluminium dish is pressed together on bottom of pot body, so that the projection in rustless steel Dropbox is embedded in inside aluminium dish；
(4) heated using brazing device, and controlled heating-up temperature, make heating-up temperature reach the melt temperature of solder
350℃-400℃.
(5) natural cooling, makes pot, Dropbox and aluminium dish be connected in one.
Further, in step (1), described solder joint is no less than 30, and equidistant uniform.
The invention has the beneficial effects as follows：
1st, pass through to arrange Dropbox between pot and aluminium dish, so as to pot surface segmentation is become different zonules, then
Solder is being spread, the solder of thawing is merely able to flow in the zonule limited by Dropbox so when soldering is carried out, so as to ensure
There is pad in each region, it is to avoid the region of large area no solder connection occurs, and effectively raises pot with aluminum
The bonding strength of disk.
2nd, by arranging multiple projections in Dropbox, so during being pressed, the projection will be embedded into matter
In soft aluminium dish, so as to the bonding strength of pot and aluminium dish is further increased, play a part of dual fail-safe.
3rd, described convex design becomes cylindrical tube shape structure, and is made using the softer stainless steel of quality, so
During being pressed, the raised active force for being subject to aluminium dish, the phenomenon of inside lateral bend occurs in raised free end,
So as to barb is formed, aluminium dish is hooked, so as to further improve the bonding strength of pot and aluminium dish.
