Refrigerator door shell and forming process thereof

Abstract

The invention discloses a refrigerator door shell and a forming process thereof, and relates to the technical field of refrigerators. The refrigerator door shell comprises a door shell base plate; theupper end and the lower end of the door shell base plate are each provided with a first bending structure; the first bending structure is formed by one-time bending; the bending corner radius of thefirst bending structure is less than 4mm; the left side and the right side of the door shell base plate are each provided with a second bending structure; the second bending structure is of an L-shaped structure; the second bending structure is formed by two times of bending; and the bending corner radius of the second bending structure is not less than 0.5mm and not more than 4mm. According to the refrigerator door shell provided by the invention, the problems of material accumulation, deformation, wrinkling, paint removing and the like in the existing door shell forming process can be effectively solved, technical support is provided for large-scale popularization of plane door shells, and high market application value is achieved.

Description

technical field [0001] The invention belongs to the technical field of refrigerators, in particular to a refrigerator door shell and a molding process thereof. Background technique [0002] Among the existing refrigerators, refrigerators with colored panel doors are an indispensable type of refrigerators currently sold in the market; however, during the production and molding process of color panel door shells, the left and right symmetrical door shells often have a large number of molds, which cannot be used universally. At the same time, in the process of forming the door shell, the traditional door shell bending forming process is to bend the side with a bending height of about 3mm at the end of the door shell to perform a U-shaped bend; between the U-shaped bend and the 3mm side At the intersection, the short side of the side is in a state of compression, and the compression will produce more material, and the extra material will flow in a direction that is conducive to ...

[0002] Among the existing refrigerators, refrigerators with colored panel doors are an indispensable type of refrigerators currently sold in the market; however, during the production and molding process of color panel door shells, the left and right symmetrical door shells often have a large number of molds, which cannot be used universally. At the same time, in the process of forming the door shell, the traditional door shell bending forming process is to bend the side with a bending height of about 3mm at the end of the door shell to perform a U-shaped bend; between the U-shaped bend and the 3mm side At the intersection, the short side of the side is in a state of compression, and the compression will produce more material, and the extra material will flow in a direction that is conducive to its flow, thus causing the side to be squeezed to form small folds, material accumulation, deformation, and wrinkling Phenomena such as paint peeling and other phenomena directly affect the appearance of the refrigerator, so it is difficult to make the rounded corners of the folding U small; the flat door shell and the small R corners match, giving people a tough feeling, and the large R corners often give people a sense of strength. An unrefined and bulky feeling, which also limits the development of flat door shells
