Combination Method of Heating Device of Pot/Kettle

Abstract

A combination method of a heating device of a pot/kettle includes pre-casting an electric heating tube or a magnetically conducting metal into an aluminum block. Then, the aluminum plate, the aluminum block and the pot/kettle are heated to reach a preset temperature. Then, the aluminum plate, the aluminum block and the pot/kettle are stamped at a high speed so that the aluminum plate between the pot/kettle and the aluminum block is compressed instantaneously so as to combine the aluminum block with the bottom of the pot/kettle tightly and closely.

1 . A combination method of a heating device of a pot/kettle, with an aluminum plate being disposed between a pot/kettle and an aluminum block, and with the pot/kettle being combined with the aluminum block by a high-speed stamping process, and the combination method comprising the following procedures:
 (1) pre-casting an electric heating tube or a magnetically conducting metal into an aluminum block;   (2) performing a preheat step to heat the aluminum plate, the aluminum block and the pot/kettle to reach a temperature ranged between 200° C. and 450° C.;   (3) providing a die assembly for placing the aluminum block, with the electric heating tube or the magnetically conducting metal facing downward;   (4) placing the aluminum plate on the aluminum block;   (5) placing the pot/kettle above the aluminum plate, with a bottom of the pot/kettle facing downward;   (6) performing a high-speed stamping process to stamp a bottom of an interior of the pot/kettle at a high speed, to squeeze and rub the aluminum plate which is filled with the bottom of the pot/kettle; and   (7) combining the aluminum plate and the bottom of the pot/kettle with the aluminum block tightly and closely to form a product.   
     
     
         2 . The method of  claim 1 , wherein the aluminum block and the aluminum plate are placed into a heating furnace to perform the preheat step, and the pot/kettle is heated by a high frequency to reach a preset temperature and then placed on the die assembly to perform the high-speed stamping process. 
     
     
         3 . The method of  claim 1 , wherein the die assembly is formed with a covering edge, and when the pot/kettle or an intermediate pot is placed on the aluminum plate, the covering edge of the die assembly seals a gap defined between the bottom of the pot/kettle or the intermediate pot and the aluminum block to prevent the aluminum plate from being squeezed outward, so that the aluminum plate is filled with the gap.
