Abstract
The utility model relates to a stainless steel cooker with a composite packing bottom. Composite packing bottoms of existing stainless steel cookers are all made of stainless steel and aluminum, and the structure of existing stainless steel cookers can not be realized to use copper materials with better heat conducting and heat insulation performance as an outer packing bottom. The utility model comprises an inner cooker bottom, an aluminum interlayer, and an outer packing cooker bottom. The utility model is characterized in that the aluminium interlayer is provided with a plurality of bulges and is embedded into a rivet body in the outer packing cooker bottom. The structure can make the aluminium interlayer and the outer packing cooker bottom combined more firm. Thus, the utility model solves the problem that copper materials can not be used as an outer packing cooker bottom anciently.
Description
The utility model belongs to the stainless-steel pan at the bottom of a kind of superpacket.
Stainless-steel pan has advantage such as be difficult for getting rusty, attractive in appearance, but the bad shortcoming of heat conductivity heat-insulating performance is arranged, so the stainless-steel pan of existing higher gears all adopts the structure at the bottom of the superpacket, be that the bottom of a pan is the bottom of a pan-aluminium interlayer in the stainless steel-three layers of compound structure in the stainless steel outsourcing the bottom of a pan (referring to Fig. 1), this structure is to improve the heat conductivity heat-insulating performance of stainless-steel pan with aluminium interlayer, and its processing method mainly is that the method with the friction of soldering or pressure makes bottom be combined into type inside and outside aluminium interlayer and the stainless steel.At the bottom of doing outsourcing with stainless steel, its heat conductivity heat-insulating performance still can not be improved to greatest extent, therefore it would be desirable with copper and make the outsourcing bottom material, but because copper is inconsistent to stainless best brazing temperature to the best brazing temperature and the aluminium of aluminium, so if once hot-forming with the method for soldering, its face of weld can't pass 250 ℃ of chillings in conjunction with majority and tests unseparated examination criteria.If with the method for traditional pressure friction,,, be easy to peel off so that the aluminium interlayer after compound combines with copper surrounding layer is not firm then again because the effect of aluminium lamination and copper layer generation eutectic bond is bad.
The utility model aims to provide the stainless-steel pan at the bottom of a kind of superpacket, and the structure at the bottom of its superpacket combines more firmly with aluminium interlayer at the bottom of can making outsourcing.
The technical scheme that realizes above-mentioned purpose is: comprise the interior the bottom of a pan (2) that mutual face connects at the bottom of the superpacket of the utility model pot body (1), aluminium interlayer (3) and the outsourcing the bottom of a pan (4) is characterized in that: described aluminium interlayer is provided with several projections and is embedded to the shaft of rivet (5) in the outsourcing the bottom of a pan.
Can adopt traditional pressure rubbing manipulation machine-shaping at the bottom of the compound pot of said structure, just before hot pressing, on the outsourcing the bottom of a pan, process earlier several riveted holes, like this when utilizing friction press that three layers of the bottom of a pan on the mould are applied instant impact, can make near the aluminium interlayer of hot melt state on the one hand as the conventional pressure friction method of forming, produce eutectic with inside and outside the bottom of a pan contact-making surface and combine, can be extruded to again on the other hand in the riveted holes in the outsourcing the bottom of a pan, form structure with the riveted joint of the outsourcing the bottom of a pan.
Increased the syndeton of riveted joint between the aluminium interlayer at the bottom of the utility model compound pot and the outsourcing the bottom of a pan, so in conjunction with firm, be difficult for peeling off, thereby in the time of at the bottom of doing outsourcing with copper material, can remedy copper material and the not firm deficiency of aluminium interlayer eutectic bond, make the composite bottom-clad stainless steel cooker of doing at the bottom of the outsourcing with copper material also can reach instructions for use.

Embodiment 1 explanation
This example is that diameter is the 21cm composite bottom-clad stainless steel cooker, its copper outsourcing the bottom of a pan 4 for periphery upwards hold up encase the aluminium interlayer periphery bowl structure (referring to Fig. 2), set projection of aluminium interlayer and the shaft of rivet 5 diameters of imbedding the outsourcing the bottom of a pan are 3mm, and hold up in the circumferential wall of part and near in the layer body of rounded bottom surface circumferential edges (referring to Fig. 2, Fig. 3) in the outsourcing the bottom of a pan that is evenly distributed on thick 0.5mm.
This example is in process, earlier the copper outsourcing the bottom of a pan is made the disk shape, making a call to the concentric circular riveted holes of two circles equably near the position of circumferential periphery, the riveted holes diameter is 3mm, again disk is struck out bowl-shape that periphery holds up, the outer ring riveted holes is positioned on the sidewall of holding up, the inner lane riveted holes is positioned at the bottom, then with circular aluminium sheet, the bowl-shape outsourcing the bottom of a pan and the interior the bottom of a pan concentric locating of pot body, being heated to temperature near the aluminium hot melt is placed on the mould and applies instant impact with friction press, can make aluminium sheet and inside and outside the bottom of a pan contact-making surface produce eutectic bond on the one hand near the hot melt state, be extruded in the riveted holes that embeds the outsourcing the bottom of a pan on the one hand, form the compound syndeton of its crystalline substance-riveted joint in the aluminium interlayer and the outsourcing the bottom of a pan, make the outsourcing the bottom of a pan and aluminium interlayer strong bonded, be difficult for peeling off.
Embodiment 2 explanations
The shaft of rivet 5 of the set projection of this routine aluminium interlayer penetrates the outsourcing the bottom of a pan 4, and the end face of the shaft of rivet exposes on the face of the outsourcing the bottom of a pan, and the cross section of the shaft of rivet is
Shape.
Shaft of rivet cross section can adopt different pattern, to beautify the external sight of pot.
