Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0031] The method for preparing a refrigerator liner with U-shaped large and small panels and a Z-shaped bottom plate of the present invention is used for preparing a refrigerator liner from a U-shaped large panel, a U-shaped small panel and a Z-shaped bottom panel. Such as figure 1 , figure 2 , image 3 shown. figure 1 , figure 2 , image 3 For an upside-down freezer liner, 3901 is a Z-shaped bottom plate, 3902 is a U-shaped large enclosure, and 3903 is a U-shaped small enclosure. The U-shaped large enclosure 3902 and the U-shaped small enclosure 3903 are mutually riveted to form a mouth-shaped enclosure. L1 and L2 are two riveting lines where the U-shaped large enclosure 3902 and the U-shaped small enclosure 3903 are riveted to each other. The mouth-shaped coaming plate and the Z-shaped bottom plate 3901 are then riveted to finally become a semi-fi...

Abstract

The invention discloses a method for preparing a refrigerator liner by U-shaped large and small surrounding plates and a Z-shaped baseplate. The method comprises seven steps in sequence: mouth-shapedsurrounding plate riveting, baseplate pre-riveting, four-round-angle riveting, vertical edge and end edge synchronous riveting, side edge and end edge synchronous riveting, short side edge step-by-step riveting and riveting line gluing. In the mouth-shaped surrounding plate riveting, two end lines of the U-shaped large surrounding plate and the U-shaped small surrounding plate are riveted to forma mouth-shaped surrounding plate. In the baseplate pre-riveting, multiple points are selected on combined corner lines of the Z-shaped baseplate and the mouth-shaped surrounding plate for synchronousriveting. In the four-round-angle riveting, four round angles are riveted by two steps. In the vertical edge and end edge synchronous riveting, two vertical corner lines and high end corner lines aresynchronously riveted. In the side edge and end edge synchronous riveting, two long side corner lines and low end corner lines are synchronously riveted. In the short side edge step-by-step riveting,two short side corner lines are riveted step by step. The riveting method is convenient for automatic production equipment to realize automatic production.

Description

technical field [0001] The invention relates to an automatic production line for a refrigerator liner. Background technique [0002] Freezer liner panels are used to isolate the freezer liner and refrigeration components. The inner tank panel of the freezer is usually made of patterned aluminum plate. Usually, the inner tank panel of the freezer is formed by riveting the U-shaped panels made of two patterned aluminum plates to each other to form a mouth-shaped panel and then riveting the bottom plate. Two U-shaped coamings, one large and one small, are riveted to form a mouth-shaped coaming, and then the mouth-shaped coaming is riveted with the Z-shaped bottom plate to form a stepped refrigerator liner coaming. Under the prior art, the riveting between the two U-shaped coaming plates and the Z-shaped bottom plate is done manually. The Z-shaped bottom plate has a total of ten sides. Two of the sidelines are bending lines and do not need to be riveted, and the remaining ei...
