Abstract

A manufacturing process for a double-layer special-shaped flat teapot, comprising the following steps: taking an upper inner container (11) and a lower inner container (12), and after placing the upper inner container (11) and the lower inner container (12) into an inner container spot-welding clamp (2) to perform spot-welding, performing seal-welding to form an inner container body (1); and taking a left casing (31) and a right casing (32) and placing the left casing (31), the inner container body (1) and the right casing (32) into a casing spot-welding clamp (5) to perform positioning spot-welding; initially fixing the inner container body (1) and a casing body (3) to form a kettle body (6); putting the kettle body (6) into a casing welding clamp (7), and seal-welding the casing body (3); pushing an inner container mouth part (112) to move towards the internal part of the casing body (3) until the distance between the outer edge of a mouth part welding flange (111) and the outer edge of a casing mouth part (33) is length D; cutting off the part, of which the distance exceeding the outer edge of the mouth part welding flange (111) is length D, of the casing mouth part (33), and seal-welding the contact position of the mouth part welding flange (111) and the casing mouth part (33) after cutting.

Description

technical field [0001] The invention relates to a manufacturing process of a pot, in particular to a manufacturing process of a double-layer special-shaped flat pot. Background technique [0002] Most of the existing kettles use some regular shapes as the shape of the kettle body. The shape of the kettle body that is most used in the market is cylindrical. The body of this shape includes the wall and the bottom surface. The manufacturing process is relatively simple. The metal tube is placed in the stamping die, and it is continuously stretched by the stamping die to form the wall of the pot body, and then the bottom surface of the pot body is directly welded to the wall surface by welding process to form a sealed pot body. However, with the development of society, the traditional standard-shaped kettles cannot meet the various needs of people in daily life, so it is necessary to provide kettles with different shapes. However, the shape of special-shaped pots manufactured b...
