Summary of the invention
The purpose of this invention is to provide a kind of aluminum pot preparation method, it is effective that it has use habit, culinary art that made pan meets people, and simple, the lower-cost characteristics of preparation technology.
To achieve these goals, the technical scheme that the present invention adopted is: the aluminum pot preparation method includes following steps successively:
A) get the raw materials ready: aluminium sheet is cut to the disk blank;
B) evenly stretch: the disk blank is evenly stretched forms evenly pot body;
C) non-homogeneous stretching: the pot wall to even pot body carries out non-homogeneous stretching, forms non-homogeneous pot body;
D) forging and pressing: non-homogeneous pot body is forged and pressed finishing.
Said step D) repaiies the burr operation afterwards.
Said step C) and step D) between flat mouthful of operation arranged.
The bottom of a pan of the even pot body that forms said step B) is with the average thickness d of pot wall: 3.9mm≤d≤4.2mm.
The average thickness D in the bottom of a pan of the non-homogeneous pot body that forms said step C) is: D >=4.5mm.
The present invention compares the advantage that is had with prior art: 1, made pan meet people use habit, the culinary art effective.The bottom of a pan thickness of the made aluminum pot of aluminum pot preparation method of the present invention is thicker, average thickness can remain on about 4.5mm or more than, meet people's use habit, and because the bottom of a pan heat transfer rate is slower, thereby the culinary art effect is better.2, preparation technology is simple, cost is lower.Aluminum pot preparation method of the present invention is the basis with the drawing and forming method, on the basis that increases the bottom of a pan thickness, the pot wall is carried out attenuate, adopts the Forging Technology finishing afterwards.Like this, reach the preparation effect of die cast method, but avoided the complicated procedures of forming of extrusion process, comparatively simple, reduced preparation cost.Simultaneously, avoided environmental pollution.
The specific embodiment
The following stated is merely preferred embodiment of the present invention, does not therefore limit protection scope of the present invention.
Embodiment 1, sees shown in Figure 1: the aluminum pot preparation method includes following steps successively:
A) get the raw materials ready: aluminium sheet is cut to the disk blank, and disc thickness is 8mm.
B) evenly stretch: the disk blank is evenly stretched forms evenly pot body.Used stretcher is stretching-machine commonly used.After the stretching, the bottom of a pan is comparatively even with the thickness of pot wall.That is, the bottom of a pan is d=3.9mm with the average thickness d of pot wall.
C) non-homogeneous stretching: the pot wall to even pot body carries out ironing, simultaneously, thickening is carried out in the bottom of a pan of even pot body handle, and forms non-homogeneous pot body.The equipment that adopts is ironing machine commonly used.After the stretching, the bottom of a pan average thickness D is 4.5mm, and pot wall average thickness is 2.5mm.At this moment, because unbalance stress in the non-homogeneous drawing process of pot body, thereby inevitably can cause the local transition of pot body smooth inadequately.
D) forging and pressing: non-homogeneous pot body is forged and pressed.This step is to step C) the smooth inadequately pot body that forms repairs, thereby the pan outward appearance met the requirements.
Optimize step D) repair the burr operation afterwards.Like this, be convenient to prepare the more smooth pan of appearance.
Further, step C) and step D) between flat mouthful of operation arranged.Like this, it is comparatively smooth to be convenient to the oral area of pot body.
Certainly, aluminum pot preparation method of the present invention is at step D) afterwards, can also be as aluminum pot preparation method commonly used, comprise successively in cleaning, sandblast, welding riveted joint, the spray be coated with, polish, be coated with outward, operation such as assembling, packing warehouse-in afterwards.
The bottom of a pan average thickness of the pan that present embodiment forms is about 4.5mm; Pot wall average thickness is about 2.5mm.
Embodiment 2: only be with the difference of embodiment 1:
The bottom of a pan of the even pot body that forms step B) is with the average thickness d of pot wall: d=4.0mm;
The bottom of a pan average thickness D of the non-homogeneous pot body that forms step C) is that 4.7mm, pot wall average thickness are 2.7mm.
The bottom of a pan average thickness of the pan that present embodiment forms is about 4.7mm; Pot wall average thickness is about 2.7mm.
Embodiment 3: only be with the difference of embodiment 1:
The bottom of a pan of the even pot body that forms step B) is with the average thickness d of pot wall: d=4.2mm;
The bottom of a pan average thickness D of the non-homogeneous pot body that forms step C) is that 5mm, pot wall average thickness are 2.8mm.
The bottom of a pan average thickness of the pan that present embodiment forms is about 5mm; Pot wall average thickness is about 2.8mm.
Embodiment 4: only be with the difference of embodiment 2: the average thickness in the bottom of a pan of the even pot body that forms step B) is that the average thickness of 3.9mm, pot wall is 4.2mm.
Embodiment 5: only be with the difference of embodiment 3: the average thickness in the bottom of a pan of the even pot body that forms step B) is that the average thickness of 4.2mm, pot wall is 3.9mm.
