Problems solved by technology

[0003] The present invention aims at the processing of the spout in the prior art, which may lead to wire drawing on the inner surface of the inner tank, which may cause damage to the welded part of the inner tank and the outer shell or produce tiny gaps, resulting in the failure of the vacuum layer or the use of vacuum insulation. Defects such as shortened lifespan provide a new manufacturing method for pots

Abstract

The invention discloses a manufacturing method of a kettle. The manufacturing method comprises the following steps of: a, taking a pipe for water swelling; b, cutting to obtain a kettle mouth blank with a small convex part, then shaping, and cutting again to form a kettle mouth; c, cutting the kettle mouth blank to obtain a kettle mouth connecting body, and then turning a connecting step; d, taking an inner container, aligning the kettle mouth connecting body with the inner container, and then welding; e, taking a shell, aligning the shell with the connecting step, and then welding; f, taking a shell bottom, aligning the shell bottom with the shell, and then welding to obtain a kettle body semi-finished product; g, carrying out vacuumizing operation to form a vacuum layer; and h, taking a handle, and connecting the handle with the shell and the kettle mouth connecting body to complete the manufacturing of the kettle. Through the steps, when the kettle with the kettle mouth is manufactured, scratches such as drawing wires cannot be formed on the surface of the kettle mouth, the deformation of the inner container and the shell cannot be caused, and the welding position of the inner container and the shell cannot be damaged, so that the kettle mouth with a smooth surface can be obtained, and the heat preservation effect of the obtained kettle can be guaranteed.

Description

technical field [0001] The present invention relates to a pot, in particular to a method for making a pot. Background technique [0002] At present, when the kettle with the spout is manufactured, the inner container and the outer shell are generally manufactured earlier, and the inner container and the outer shell are welded and then evacuated to obtain a vacuum layer, and finally the spout is processed at the mouth of the pot. Although the manufacturing method of this kind of pot can obtain a pot with a spout, in the process of processing the spout, the spout is obtained by pressing out the shape of the spout from the inside of the inner tank. Drawing occurs on the inner surface of the liner, destroying the appearance of the liner. On the other hand, in the process of deforming the mouth of the inner tank and the outer shell into a spout, the welds of the inner tank and the outer shell may be damaged or produce tiny gaps, which will lead to failure of the vacuum layer or ...
