MANUFACTURING METHOD FOR SOUP POT WITH PARTIAL CONCAVE-CONVEX PATTERNS ON OUTER SURFACE THEREOF

Abstract

The invention discloses a manufacturing method for a soup pot with partial concave-convex patterns on an outer surface thereof. The method comprises: preparing a plane blank for forming a pot body; screen-printing a layer of ink with preset patterns on a surface of the blank of the pot body; screen-printing a layer of ink with preset patterns on a bottom surface of the blank of the pot body; etching at positions where no patterns occurs on the surface of the blank of the pot body; stretching the blank of the pot body to form a soup pot, and flashing the edge of the pot body; and spraying a nonstick pan coating on the blank of the pot body, and polishing with abrasive paper at positions where the convex patterns occur and where no pattern occurs.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention is further described hereinafter by embodiments, with reference to the drawings, wherein:

[0016] FIG. 1 is a schematic view of a soup pot according to an embodiment of the present invention; and

[0017] FIG. 2 is an enlarged sectional view at area B in FIG. 1.

DETAILED DESCRIPTION

[0018] The technical solutions of the present invention are further described by following specific embodiments.

[0019] A manufacturing method for a soup pot with partial concave-convex patterns on an outer surface thereof according to the disclosure comprises the following steps.

[0020] Step S1: preparing a plane blank for forming a pot body.

[0021] In step S1, a three-layer steel composite plane blank is selected, its outer and inner layers are stainless steel, while its middle layer is formed by compounding aluminum alloy. Since the aluminum alloy of the middle layer has quick heat conduction and can be evenly heated, the heat is evenly transferred to the stainless steel of the inner layer. Consequently, food in a soup pot made of the plane blank can be heated evenly during cooking, and thus a smokeless effect is achieved.

[0022] Step S2: screen printing a layer of ink with preset patterns on a surface of the blank of the pot body, and drying and curing the ink.

[0023] Step S3: screen printing a layer of ink with preset patterns on a bottom surface of the blank of the pot body, wherein the blank at position where no pattern occurs is not covered, and then drying and curing the ink.

[0024] The preset patterns are polygonal patterns evenly distributed in matrixes, such as square patterns, hexagonal patterns, and other honeycomb patterns.

[0025] Step S4: etching at positions where no patterns occur on the surface of the blank of the pot body, and then cleaning and drying the ink.

[0026] Step S5: stretching the blank of the pot body to form a soup pot, and flashing the edge of the pot body.

[0027] Step S6: spraying a nonstick pan coating on the blank of the pot body, and polishing with abrasive paper at positions where the convex patterns occur and where no pattern occurs, so that, at the positions where the convex patterns occur and where no pattern occurs, no non-stick pan coating occurs.

[0028] With reference to FIGS. 1 and 2, an etching depth a in step S4 ranges from 0.1 mm to 0.3 mm.

[0029] A thickness b of the non-stick pan coating sprayed in step S6 is less than 0.1 mm.

[0030] A space of the convex patterns in step S6 is within 1 mm.

[0031] In the embodiments of the present invention, the pot body at the positions where no patterns occurs is also etched to ensure a uniform overall thickness of the blank of the pot body, so as to prevent the spot body from fractures at the border between the positions where the concave-convex patterns occur and the positions where no concave-convex pattern occurs, when the blank of the pot body is deeply stamped and stretched, ensuring a yield of products. Therefore, a finished product according the invention can have a surface with a concave-convex patterned lower part and a polished smooth upper part, to provide a better decorative effect.

[0032] The above description of the disclosed embodiments enables those skilled in the art to achieve or use the present invention. Various modifications made to these embodiments are apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments herein, but shall conform to the widest scope consistent with the principles and novel features disclosed herein.
