Description
Technical field
The invention relates to a kind of kitchen cooker, dual-purpose die casting composite bottom aluminum pot and manufacture method thereof that particularly a kind of gas-cooker and electromagnetic stove can be used.
Background technology
Along with economic development and scientific and technological progress, the income of residents, living standard and quality of the life have had and have increased substantially, and the family that simultaneously has gas-cooker and electromagnetic stove is more and more, and gas-cooker and electromagnetic stove have been come into huge numbers of families.But traditional aluminum pot can only be used on gas-cooker, can not on electromagnetic stove, use.
People's composition metal magnetic conduction circular disc at the bottom of aluminum pot pan for this reason, its concrete structure is several projections of moulding in advance at the bottom of pan, metal magnetic conducting circular disc is provided with the through hole matching with several projections, then by the mode of extruding, make projection deformation, metal magnetic conducting circular disc riveted joint is fixed at the bottom of pan on.But this structure in use has the following disadvantages: because metal magnetic conducting circular disc is different from the thermal coefficient of expansion of aluminium pot, swell increment while using on gas-cooker and electromagnetic stove has larger difference, metal magnetic conducting circular disc in process of expansion and contraction with separated at the bottom of pan, periphery perk, cause between metal magnetic conducting circular disc and pot body heat conductivility undesirable, the thermal efficiency declines.
In order to solve metal magnetic conducting circular disc and pot body separation problem, people embed at least four blocks of mutual disjunct metal guide magnetic sheets at the bottom of pan, expose at each metal guide magnetic sheet outer surface middle part, each metal guide magnetic sheet outer surface flushes with the bottom of a pan, the aluminium alloy in the bottom of a pan is coated and fixed metal guide magnetic sheet edge, the swollen amount difference of heat between unitary piece of metal magnetic conduction sheet and aluminium pot significantly reduces, thereby effectively solves the metal guide magnetic sheet causing because thermal coefficient of expansion is different between metal magnetic conducting sheet and the aluminium pot problem that comes off.But said structure still has the following disadvantages: the one, at the bottom of embedding pan by least four blocks of metal guide magnetic sheets, and be coated and fixed by aluminium alloy edge, make metal guide magnetic sheet surface and pan basal surface close contact, after long-time use or when pot body is overheated, can make equally metal guide magnetic sheet in process of expansion and contraction with separated at the bottom of pan, cause heat conductivility between metal guide magnetic sheet and pot body to decline, the thermal efficiency reduces; The 2nd, production and processing trouble, inefficiency.For this reason, many people have spent for it a large amount of painstaking effort and cost is developed and studied, but not yet have so far rational product to emerge.
Summary of the invention
For overcoming the existing above-mentioned defect of the compound aluminum pot of existing die casting, the object of the invention be to provide a kind of simple and reasonable, manufacture easy to process, production efficiency is high, percent defective is low, combustion gas and the dual-purpose composite bottom boiler of electromagnetism and the manufacture method thereof of compound solid and reliable, good heat conductivity, long service life.
The invention solves the problems of the technologies described above adopted technical scheme, it comprises the aluminium pot of die cast, metal guide magnetic sheet, aluminium pot has flat bottoms, described metal guide magnetic sheet is provided with the combination of interval or through hole or interval and through hole, the composition surface of metal guide magnetic sheet is rough matsurface, metal guide magnetic sheet is forged and pressed and is pressed into the flat bottoms of aluminium pot concordant with flat bottoms by heating, the aluminium molecule of aluminium pot bottom is squeezed and fills and leads up interval or through hole or gap and through hole combination and fix metal guide magnetic sheet, and it is bonding to penetrate into the interior generation of the rough matsurface of metal guide magnetic sheet physics.
The further scheme of the invention, described metal guide magnetic sheet is provided with some intervals of central through hole and periphery, connects the structure of some magnetic conduction blades or magnetic conduction sector in the middle of forming for magnetic conduction annulus muscle sheet, periphery.
