Abstract
The present invention is a kind of electric pressure cooking saucepan outer pot processing method and the outer pot of preparation thereof, and described method, including 1) selection: selecting corrosion resistant plate or the disk of A3 cold-rolled steel sheet, its material thickness is 0.8～1.2 millimeter；2) stretching: carry out being drawn into outer pot shape by disk；3) bulging: the outer pot stretched in above-mentioned steps is carried out bulging, the outer pot diameter after bulging and height increase, and pot mouth thickness of flange increases than material thickness, and pot body and bottom thickness below pot mouth flange reduce than material thickness；4) trimming: remove outer pot excess stock by diel；5) flange: outside pot mouth flange portion carries out flange, forms pot tooth；Described outer pot, pot mouth is provided with flange, and whole pot is one-body molded, bigger than the pot body under it and the bottom of a pan thickness 0.10～0.30 millimeter of the pot tooth thickness that described pot mouth flange flange is formed.The present invention has that low cost, anti-pressure ability be strong, process stabilizing, appearance looks elegant, the advantage being suitable for batch production.
Description
Technical field
The present invention relates to electric pressure cooking saucepan, a kind of electric pressure cooking saucepan outer pot processing method and the outer pot of preparation thereof.
Background technology
According to regulation in GB4706.19-2008 " particular/special requirement of the safe liquid heater of domestic and similar applications electrical equipment ", pressure being gradually increased to hydraulic pressure the specified cooking pressure of six times, container should not be destroyed.In order to meet the requirement of this standard, existing electric pressure cooking saucepan outer pot is the requirement being met standard by enough thickness.But when electric pressure cooking saucepan works, not being all parts of outer pot pressure of all bearing six times, bear the maximum position of pressure at pot mouth flange portion, the pressure that other parts are born is respectively less than pot mouth flange portion.Therefore, being thickened by whole outer pot, the cost that can make electric pressure cooking saucepan outer pot is high, and will also result in waste of material.
In order to solve this problem, people devise many pressure cooker with thin wall patents.Such as Chinese patent CN1568876B proposes to be welded with reinforcement at pot wall below cylindrical projection in pot.This structure can play and strengthens pot edge thickness and improve the effect of resistance to tension.But this structure electric pressure cooking saucepan produce time, outer pot outward appearance unsightly, needs to buy welding equipment, simultaneously welding difficulty is big, cost is high, manufacturing process is poor, and percent defective is higher.
Summary of the invention
Present invention aim to overcome that the problems referred to above, it is provided that a kind of low cost, anti-pressure ability are strong, process stabilizing, appearance looks elegant, the electric pressure cooking saucepan outer pot processing method of batch production of being suitable for.
It is a further object of the present invention to provide a kind of outer pot using above-mentioned processing method to prepare.
The technical scheme realizing the object of the invention is: the processing method of a kind of electric pressure cooking saucepan outer pot, it is characterized in that, comprises the following steps:
1) selection: selecting corrosion resistant plate or the disk of A3 cold-rolled steel sheet, its material thickness is 0.8～1.2 millimeter；
2) stretching: carry out being drawn into outer pot shape by disk；
3) bulging: the outer pot stretched in above-mentioned steps is carried out bulging, outer pot diameter after bulging increases than the outer pot diameter before bulging, outer pot height before outer pot aspect ratio bulging after bulging increases, outside pot mouth thickness of flange after bulging increases than material thickness, and the pot body below outside pot mouth flange and bottom thickness after bulging reduce than material thickness；
4) trimming: remove outer pot excess stock by diel；
5) flange: outside pot mouth flange portion carries out flange, forms pot tooth.
The 3rd of above-mentioned processing method) in step, the outer pot diameter after described bulging increases by 6.7～8.8 millimeters than the outer pot diameter before bulging.
The 3rd of above-mentioned processing method) in step, the outer pot height before the outer pot aspect ratio bulging after described bulging increases by 3.0～6.0 millimeters.
The 3rd of above-mentioned processing method) in step, the outside pot mouth thickness of flange after described bulging increases by 0.05～0.15 millimeter than material thickness.
The 3rd of above-mentioned processing method) in step, the pot body below outside pot mouth flange and bottom thickness after described bulging reduce 0.05～0.15 millimeter than material thickness.
The technical scheme realizing another object of the present invention is, a kind of electric pressure cooking saucepan outer pot prepared by above-mentioned processing method, pot mouth is provided with flange, it is characterized in that, whole pot is one-body molded, bigger than the pot body under it and bottom thickness 0.10～0.30 millimeter of the pot tooth thickness that described pot mouth flange flange is formed.
The invention has the beneficial effects as follows: owing to pot mouth flange material thickness is increased, pot pot body and base material thickness reduce, therefore, this outer pot low cost, anti-pressure ability are strong, process stabilizing, appearance looks elegant, be suitable for batch production；By pressing equipment and die drawn bulging, guarantee that the increase of outside pot mouth flange material thickness, pot pot body and base material thickness reduce, it is not necessary to extra part processing, reduce sawing sheet size, improve the higher anti-pressure ability of same material.The processing method of the present invention is the most applicable and general pressure cooker, falls within protection scope of the present invention.

Fig. 2 is the outer pot structural representation after bulging of the present invention；
Fig. 3 is structural representation after pressure cooker outer pot flange of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings and the detailed description of the invention of the present invention is described further by example.
As shown in Figure 1 to Figure 3, the processing method of a kind of electric pressure cooking saucepan outer pot, it comprises the following steps:
1) selection: selecting corrosion resistant plate or the disk of A3 cold-rolled steel sheet, its material thickness is 0.8～1.2 millimeter；
2) stretching: carry out being drawn into outer pot shape as shown in Figure 1 by the steel plate disk chosen；
3) bulging: the outer pot stretched in above-mentioned steps carries out bulging, the second expanding die stretching die and blank holder increase stretching bank, stop the flowing of outside pot mouth flange 1 material.Outer pot diameter after bulging increases by 6.7～8.8 millimeters than the outer pot diameter before bulging, outer pot height before outer pot aspect ratio bulging after bulging increases by 3.0～6.0 millimeters, pot mouth flange 1 thickness after bulging increases by 0.05～0.15 millimeter than material thickness, pot body 2 and bottom 3 thickness of the outside pot mouth flange less than 1 after bulging reduce 0.05～0.15 millimeter than material thickness, as shown in Figure 2；
4) trimming: remove outer pot excess stock by diel；
5) flange: outside pot mouth flange portion carries out flange, forms pot tooth 11, as shown in Figure 3.
As it is shown on figure 3, the present invention is a kind of electric pressure cooking saucepan outer pot, pot mouth is provided with flange 1, it is characterized in that, whole pot is one-body molded, and described pot mouth flange 1 flange forms the thickness of pot tooth 11 than the pot body 2 under it and big 0.10～0.30 millimeter of the bottom of a pan 3 thickness.
