Technical field
The utility model belongs to the kitchen utensils technical field, is specifically related to a kind of steel disc aluminum pot with composite bottom with flanging bore.
Background technology
At present, various aluminum pot with composite bottom structures are numerous.Case 1: China Patent No. is that 02217063.4 patent documentation discloses a kind of " (composite pan bottom of aluminium matter pot) " of cold-extrusion technology its characteristic principle is in this technical scheme: the bottom composition metal steel disc of aluminum pot, the plane of this steel disc punches out a plurality of counter sinks, steel disc is fitted in carry out cold extrusion on the pot outer bottom plane of aluminium matter pot and make its adhesive bonding on the bottom of a pan.But it comes with some shortcomings: counter sink presents yi word pattern after embedding the bottom of a pan on the steel disc of above-mentioned aluminium matter pot, only has extruding force up and down at the bottom of compound bottom sheet and the aluminum pot, face forms many small cylinders in the aluminium matter the bottom of a pan, especially aluminium matter and steel heat rise and the having a long way to go of shrinkage factor, aluminium matter cylinder is subject to repeatedly the extrusion stretching in cross section after the expanding with heat and contract with cold repeatedly in using heating process, thereby cause the cylindrical face of cylinder of steel disc flange hole wall and aluminium matter to produce the form inefficacy that function and adhesive bonding are inlayed in the slit impact, bulge will occur after long-term the use, alice, the phenomenon such as come off causes affecting and reduces service life.
Case 2: China Patent No. is that " aluminum pot with composite bottom " its characteristic principle in this technical scheme that 200920316756.1 patent documentation discloses a kind of Forging Technology is: (1) steel disc composite surface is provided with netted and the grooving circle shape, utilizes grooving to offset the expansion of a part of aluminium matter and steel disc and difference and the exhaust of shrinkage factor.(2) this steel disc is that effect by leveling face heat conduction makes heat conduction accelerate to play energy-conserving action.(3) bottom of pot body and steel disc forge by heating and are bonded into one.
The above-mentioned aluminum pot with composite bottom key element that also comes with some shortcomings: the indent standard of (1) customer requirement is difficult to reach.(2) processing technology requires too highly, bulge, alice often can occur, come off and the defective such as the difficult control of bonding force indent not up to standard, causes accidentally just causing in enormous quantities directly scrapping.
The utility model content
For the problem that prior art exists, the object of the invention is to design provides a kind of steel disc with flanging bore to be connected the more accurately technical scheme of aluminum pot with composite bottom of bonding more reliable, more firm, indent requirement with the aluminium matter the bottom of a pan.
Described a kind of steel disc aluminum pot with composite bottom with flanging bore, comprise aluminum pot and press the compound compound bottom sheet that is arranged on the aluminum pot the bottom of a pan by cold extrusion or forge hot, it is characterized in that described compound bottom sheet is provided with the flange circular hole, the described aluminum pot the bottom of a pan is provided with the cylinder that embeds for the flange circular hole.
Described a kind of steel disc aluminum pot with composite bottom with flanging bore, the flange that it is characterized in that described flange circular hole is the circular arc flange.
Described a kind of steel disc aluminum pot with composite bottom with flanging bore is characterized in that the described aluminum pot the bottom of a pan is provided with and the corresponding circular troughed belt of the flange of flange circular hole, and the flange button of described flange circular hole is embedded in the circular troughed belt.
Described a kind of steel disc aluminum pot with composite bottom with flanging bore is characterized in that the flange of described flange circular hole is the U-shaped structure of back-off at aluminum pot the bottom of a pan Formation cross-section by cold extrusion or forge hot pressure afterwards.
Above-mentioned a kind of steel disc aluminum pot with composite bottom with flanging bore, simple in structure, reasonable in design, compared with prior art have following beneficial effect: 1) compound bottom sheet arranges the flange circular hole with the circular arc flange, reduce the rate of expanding with heat and contract with cold of aluminium and steel, so that the advantages such as composite adhered fastness and resetting property of indent are guaranteed in bonding tensile failure of not expanded with heat and contract with cold; 2) the aluminum pot the bottom of a pan arranges and the corresponding cylinder of flanging bore and circular troughed belt, be combined in the bottom of a pan and the flange back-off at obtuse angle is embedded as purpose and is bonded into one with compound bottom sheet face moment generation molecule by heating forging and pressing, so that further improve the advantage such as bonding more firm in compound bottom sheet and the aluminum pot the bottom of a pan, long-term use that its bottom of a pan can not produce bulge, alice, the bad phenomenon such as come off, be particularly suitable for using at electromagnetic oven.
