TECHNICAL FIELD

[0001] The utility model relates to the field of pot manufacturing technology, especially to a brazing positioning structure of pot bottom. BACKGROUND

[0002] In the process of pot manufacturing, especially stainless steel pot, because the inner surface of stainless steel pot body needs to contact with food, 304 material is usually used to ensure the food safety of products, but because 304 material is not magnetic, it cannot be used on the electromagnetic oven, and at the same time, the heat conduction performance of 304 material is relatively poor. In order to enhance the heat conduction performance and durability of the bottom of the stainless steel pot, a composite bottom is usually additionally added to the bottom of the pot, and in the composite bottom, aluminum sheet is used as the heat conduction layer, and a bottom sheet is coated outside to protect it.

[0003] However, in the traditional pot bottom assembling and brazing process, due to the lack of effective positioning structure, the aluminum sheet and the bottom sheet are often misaligned with the pot body, which causes the bottom of the pot to be uneven after brazing, affecting the use effect and the aesthetic degree. Therefore, it is particularly important to design a structure that can ensure the accurate positioning of the pot bottom during brazing. SUMMARY

[0026] As an example, the brazing positioning structure of the embodiment of the present application is applied to a pot bottom, the pot bottom comprising a pot body 1, an aluminum sheet 2 and a bottom sheet 3, the positioning principle is as follows:

[0027] Firstly, the bottom of the pot body 1 is provided with a groove 11 for placing the aluminum sheet 2; the outer periphery of the aluminum sheet 2 is provided with a plurality of positioning protrusions 21, the other positions of the outer periphery of the aluminum sheet 2 are concave relative to the positioning protrusions 21, thereby ensuring that there is a gap between the aluminum sheet 2 and the bottom sheet 3, so that the mixture of molten brazing agent + aluminum in the brazing process is filled in the gap, and the appearance of the product is not affected by the filling of the mixture without the gap. At the same time, the inner diameter of the groove 11 is the same as the outer diameter of the aluminum sheet 2, when the aluminum sheet 2 is placed in the groove 11, the outer edge of the positioning protrusions 21 of the outer periphery of the aluminum sheet 2 is just in contact with the inner part of the groove 11, thereby the aluminum sheet 2 can be centrally placed in the groove 11, and the central positioning of the aluminum sheet 2 and the pot body 1 is realized. In addition, the bottom diameter of the bottom sheet 3 is also the same as the outer diameter of the aluminum sheet 2, when the aluminum sheet 2 and the bottom sheet 3 are butt jointed at the bottom side, the central positioning of the aluminum sheet 2 and the bottom sheet 3 is also realized.

[0028] Secondly, in order to realize the central positioning of the bottom sheet 3 and the pot body 1, the brazing positioning structure of the present application also designs a positioning jig 4 which is sleeved with the pot body 1, the positioning jig 4 is used to be sleeved on the bottom of the pot body 1; and the positioning jig 4 is provided with a butt joint hole 41, when the positioning jig 4 is sleeved on the pot body 1, the butt joint hole 41 is centrally aligned with the groove 11, and since the hole diameter of the butt joint hole 41 is the same as the outer diameter of the bottom sheet 3, when the bottom sheet 3 is placed on the bottom of the pot body 1 through the butt joint hole 41, the central positioning of the bottom sheet 3 and the pot body 1 is realized.

[0029] Therefore, the brazing positioning structure of the present application realizes the central positioning of the aluminum sheet 2 and the pot body 1 while ensuring that there is a gap between the aluminum sheet 2 and the bottom sheet 3 by providing a plurality of positioning protrusions 21 on the outer periphery of the aluminum sheet 2; and the central positioning of the bottom sheet 3 and the pot body 1 is realized by the positioning jig 4; thereby the overall central positioning of the pot bottom structure is realized.

[0030] In an embodiment, referring to Figure 3 and Figure 6The side of the positioning mold 4 is provided with an opening 42 communicated with the butt joint hole 41.

[0031] As an example, the side of the positioning mold 4 is also provided with an opening 42 communicated with the butt joint hole 41, so that the aluminum sheet 2 and the bottom covering sheet 3 can be placed into the recess 11 before brazing; and the bottom covering sheet 3 can be pre-fixed with the pot body 1 through the opening 42 by means of glue or adhesive tape after positioning, so as to prevent the bottom covering sheet 3 from moving during the removal of the positioning mold 4 or during brazing, and to ensure the stability of the positioning effect.

[0032] In an embodiment, when the aluminum sheet 2 and the bottom covering sheet 3 are placed on the pot body 1, the bottom covering sheet 3 and the pot body 1 are fixed by adhesive tape.

[0033] As an example, in order to further enhance the stability of the positioning effect between the pot body 1 and the bottom covering sheet 3, when the aluminum sheet 2 and the bottom covering sheet 3 are placed on the pot body 1, the bottom covering sheet 3 and the pot body 1 can be pre-fixed by adhesive tape, so as to prevent displacement during brazing; and the adhesive tape will be burned due to high temperature during brazing, and will not affect the product.

[0034] In an embodiment, referring to Figures 3 to 5 The positioning protrusions 21 are provided with four, and the four positioning protrusions 21 are distributed along the cross direction on the outer periphery of the aluminum sheet 2.

[0035] As an example, the positioning protrusions 21 are provided with four, and the four positioning protrusions 21 are distributed along the cross direction on the outer periphery of the aluminum sheet 2, so that the aluminum sheet 2 can be placed into the recess 11 from any direction, and the centering and alignment of the aluminum sheet 2 and the pot body 1 can be achieved.

[0036] For the embodiments of the present application, it should be further pointed out that, in the case of no conflict, the embodiments and the features in the embodiments of the present application can be combined with each other to obtain new embodiments.
