Forming method of the multiple end of aluminum pot
Technical field
The present invention relates to field shaping technique of the multiple end of aluminum pot, forming method of the multiple end of particularly a kind of aluminum pot.
Background technology
At present, the composite bottom aluminum pot on the market is the i.e. first again substrate sheet on aluminium flake of sheet material before the aluminum pot moulding, punch forming again, its weak point is: one, because technology or technology, aluminium flake and sheet metal compound good after, carry out punch forming again.This moment is because of being difficult for the location, makes after a pot embryo punching press comes out, and the degree of eccentricity in the sheet metal and the bottom of a pan is bigger, thereby influences presentation quality bottom the product and user's result of use.Two, because in the punch forming process, the bottom of a pan can be subjected to certain external force, thereby causes the bottom of a pan and sheet metal in conjunction with not firm, thus situations such as aliquation, delamination appear easily, thus cause product to be heated inhomogeneous and influence product service life.
Summary of the invention
Technical problem solved by the invention provides forming method of the multiple end of a kind of aluminum pot, makes this method can effectively control the degree of eccentricity of sheet metal and pot body and guarantees the firm degree of both combinations, to improve the performance and the service life of product.
For solving the problems of the technologies described above, the technical solution used in the present invention is: forming method of the multiple end of a kind of aluminum pot, and this method may further comprise the steps:
S10: punching press pot type:, obtain thick pot embryo the aluminium flake punch forming;
S20: trimming: remove the unnecessary rim charge of thick pot embryo oral area, form the pot embryo;
S30: sheet metal location: sheet metal and pot embryo are located with anchor clamps, and then fix, sheet metal is fixed on a pot embryo bottom;
S40: compound pot body: pot embryo and sheet metal are compounded to form composite bottom aluminum pot through high pressure.
One of improve: before carrying out described step S10, the aluminium flake surface is cleaned by elder generation, evenly is coated with on the aluminium flake surface then to oil.
Two of improvement: before carrying out described step S30, the greasy dirt on elder generation's pot embryo.
Three of improvement: the thickness of described aluminium flake is 2.5-5mm.
Four of improvement: the thickness of described sheet metal is 0.4-0.8mm.
The present invention has following beneficial effect with respect to prior art:
1. forming method of the multiple end of aluminum pot of the present invention can effectively be controlled the degree of eccentricity of sheet metal and pot body, and it can be Deviation Control in 0.5mm, and the bottom of a pan presentation quality is greatly improved.
2. forming method of the multiple end of aluminum pot of the present invention can guarantee that the multiple end of pot body is firm; Combine firm between the fastness test of the multiple end (national standard/light industry standard) that the aluminum pot that the present invention obtains can be smoothly take off the end by being heated to 250 ℃ of quenchings in room temperature water then, 25 above-mentioned loop tests earlier, bottom of pot body and sheet metal.
3. the pot body long service life that forming method of the multiple end of aluminum pot of the present invention is produced; The multiple end, the bottom of a pan that this method is produced, is firm, aliquation not, and not delamination has solved other composite bottom aluminum pot because the pot body that aliquation, delamination cause damages the problem that reduce service life.
Description of drawings:
Fig. 1 is a compound pot bottom structure schematic diagram.
The specific embodiment:
The invention will be further described below in conjunction with embodiment and accompanying drawing.
Forming method of the multiple end of the aluminum pot of present embodiment may further comprise the steps:
S10: punching press pot type:, obtain thick pot embryo the aluminium flake punch forming;
S20: trimming: remove the unnecessary rim charge of thick pot embryo oral area, form the pot embryo;
S30: sheet metal location: sheet metal and pot embryo are located with anchor clamps, and then fix, at last sheet metal is fixed on a pot embryo bottom;
S40: compound pot body: pot embryo and sheet metal are compounded to form as shown in Figure 1 composite bottom aluminum pot through high pressure.
Wherein, before carrying out step S10, the aluminium flake surface is cleaned by elder generation, evenly is coated with on the aluminium flake surface then to oil; Before carrying out step S30, the greasy dirt on elder generation's pot embryo.
In addition, the thickness of present embodiment aluminium flake is 2.5-5mm, and the thickness of sheet metal is 0.4-0.8mm.
As mentioned above, just can realize the present invention preferably, the foregoing description is preferred embodiment of the present invention only, is not to be used for limiting practical range of the present invention.All equalizations of doing according to content of the present invention change and modify, and all require scope required for protection to be contained by the present invention.
