Bending and angle wrapping equipment for refrigerator door shell

Abstract

The invention belongs to the technical field of refrigerator door shell bending, in particular to bending and angle wrapping equipment for a refrigerator door shell, and provides the following scheme that the bending and angle wrapping equipment comprises an L-shaped operation table, a bending limiting frame is fixedly connected to the outer wall of one side of the L-shaped operation table, and an angle wrapping plate is fixedly connected to the outer wall of the bending limiting frame; the outer wall, located on the upper portion and the outer wall, located on the lower portion, of the corner wrapping plate are both connected with side edge shaping plates through hinges. By arranging a third hydraulic cylinder, a limiting plate and a limiting roller, when the refrigerator door shell is bent and a bending cutter conducts extrusion bending operation, a first air cylinder is adjusted to drive the limiting roller to move to the position above the refrigerator door shell, and meanwhile the third hydraulic cylinder is adjusted to drive the limiting roller to make contact with the refrigerator door shell; the lower portion of the refrigerator door shell is limited through the limiting rollers, bending deformation of the refrigerator door shell in the bending process is prevented, meanwhile, the extrusion limiting mode is roller type extrusion, and damage to the refrigerator door shell is reduced.

Description

technical field [0001] The invention relates to the technical field of bending equipment for refrigerator door shells, in particular to bending and wrapping equipment for refrigerator door shells. Background technique [0002] The refrigerator door shell is an essential part of the refrigerator. High-end refrigerators generally use hidden end covers, which makes the mechanism of the refrigerator door shell more complicated than that of ordinary refrigerators, adding flanges on the ends and other parts. The four processes of material, flanging, U-shaped bending (bending) and corner wrapping are long and the production efficiency is low, and the four processes respectively use blanking die, flanging die, U-folding die and corner wrapping die To be done. [0003] During the bending process of the existing refrigerator door shell, the corner wrapping mold is used to wrap the end, so that the shape of the bent end is the same as that of the corner wrapping mold, but the existing...

[0002] The refrigerator door shell is an essential part of the refrigerator. High-end refrigerators generally use hidden end covers, which makes the mechanism of the refrigerator door shell more complicated than that of ordinary refrigerators, adding flanges on the ends and other parts. The four processes of material, flanging, U-shaped bending (bending) and corner wrapping are long and the production efficiency is low, and the four processes respectively use blanking die, flanging die, U-folding die and corner wrapping die To be done

[0003] During the bending process of the existing refrigerator door shell, the corner wrapping mold is used to wrap the end, so that the shape of the bent end is the same as that of the corner wrapping mold, but the existing corner wrapping mold is generally independent A plastic structure, in the bending process, the refrigerator door shell is squeezed to the corner wrapping mold by the bending knife, and the hard extrusion corner wrapping method is adopted, which is easy to cause damage to the refrigerator door shell. At the same time, through After the end of the refrigerator door shell is molded by the corner-wrapping mold, after it is taken out from the corner-wrapping mold, the bent part is prone to deformation and reset. The shape effect cannot achieve permanent shaping on the rear end of the bending, which reduces the use value of the bending angle wrapping mold
