Die-casting double-bottom cooking utensil and manufacturing method thereof

Abstract

The invention provides a die-casting double-bottom cooking utensil and a manufacturing method of the die-casting double-bottom cooking utensil, which belong to the technical field of machinery and solve the problem that a double-bottom sheet in an existing double-bottom pan body is easily deformed or easily falls off through heating. The manufacturing method comprises the following steps of A. manufacturing a metal sheet; B. punching; C. turning over edges; D. closing molds; E. casting molten aluminum; F. demolding. The die-casting cooking utensil comprises an open body which is made of an aluminum material, wherein the body is provided with a chassis for heating, the chassis is provided with the metal sheet which is made of a magnetic-conducting material, the metal sheet is provided with a plurality of through connecting holes, the chassis is provided with a plurality of connecting parts which are embedded into the connecting holes, the connecting parts and the connecting holes are in one-to-one correspondence, and a clamping structure which can be used for fixedly connecting each connecting part and the corresponding connecting hole is arranged between the connecting part and the connecting hole. The die-casting double-bottom cooking utensil has the advantages that the metal sheet is more firmly connected and does not easily fall off, and the like.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a double-bottom cooker, in particular to a die-cast double-bottom cooker and a manufacturing method thereof. Background technique [0002] At present, most of the traditional pans are made of aluminum, which is a non-magnetic material, so it cannot be used on an induction cooker. In order to make aluminum or other non-magnetic metal cookware applicable to a variety of stoves, a layer of metal sheet with good magnetic properties is generally compounded on the bottom of the cooker, so that aluminum or other non-magnetic metal cookware can be used in electromagnetic It can be used on the stove and can be applied to other stoves. [0003] For example, a Chinese patent discloses a stainless steel double bottom pot [application number: 200920050595.6; announcement number: CN201332943Y], which has a double bottom pot body. The wall and the bottom of the pot are formed with a concave p...

Problems solved by technology

[0004] However, when the above-mentioned stainless steel double bottom pot is in use, the double bottom sheet will expand after being heated, and the buffer space for the anti-deformation of the double bottom sheet is not set on the double bottom sheet, resulting in serious deformation of the double bottom sheet after being heated, especially the double bottom sheet. The center of the film may even swell and bulge, resulting in a gap in the connection with the bottom of the pot. In severe cases, the film may fall off
