Embodiment Construction

[0019] Attached below figure 1 -5 To further explain the present invention:

[0020] Such as Figure 1-2 As shown, the composite bottom pot mainly includes a pot body 1, an aluminum soaking plate 2, a through hole 3, a dot nail 4, and an aluminum riveting tube 5. The pot body 1, dot nail 4 is made of stainless steel, and the soaking plate 2, riveting The joint tube 5 is made of aluminum. The spot nails 4 can be designed as hollow or solid, and spot welded at even intervals on the outside of the bottom of the pot body 1. The soaking plate 2 is provided with through holes 3 corresponding to the spot nails 4, aluminum rivets The joint tube 5 is sleeved outside the point nail 4 in the through hole 3, and the lead flux and solder for brazing are coated between the outside of the bottom of the pot body 1 and the soaking plate 2.

[0021] image 3 It is a partial enlarged schematic diagram before riveting; at this time, the aluminum riveting tube 5 is sleeved outside the point nail 4 in...

Abstract

The compound bottom pot and its making process belongs to the field of cooking utensil technology. The compound bottom pot includes one pot body and one heat homogenizing pan outside the pot bottom, and features that the heat homogenizing pan is compounded to the pot bottom through the first riveting and the subsequent brazing with one riveting device. Owing to the combined riveting and welding, the present invention can avoid the cracking and sealing off caused by different expansion coefficients. Compared with available technology, the present invention has the advantages of simple technological process, low cost, firm connection of the compounding pot bottom, homogeneous heating, etc.

Description

Technical field [0001] A composite bottom pot and its manufacturing process belong to the field of cooking utensils and manufacturing for household daily life. Background technique [0002] The double bottom pot is popular among consumers for its energy saving and uniform heating. Most of the prior art double bottom pans directly braze aluminum soaking pans on the stainless steel pan. Due to the different thermal expansion coefficients of stainless steel and aluminum, when the combined area of ​​the pan and the soaking pan is too large or the bottom of the pan is arc-shaped, The double bottom pot is prone to seam or desoldering when heated. Summary of the invention [0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and design a composite bottom pot with firm connection, reliable quality and uniform heating. [0004] Another technical problem to be solved by the present invention is to provide a manufacturing proc...
