Embodiment Construction

[0056] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0057] A method for preparing a freezer liner according to the present invention, comprising the steps of preparing a U-shaped large enclosure, a preparation of a U-shaped small enclosure, a preparation of a Z-shaped bottom panel, a riveting step of a mouth-shaped enclosure, a step of glueing corners, and a The step of riveting the bottom plate, the step of punching the side and the step of gluing the riveting line. Wherein, the step of preparing the U-shaped large enclosure is used to prepare the patterned aluminum plate into a U-shaped large enclosure. The U-shaped small enclosure preparation step is used to prepare the patterned aluminum plate into a U-shaped small enclosure. The Z-shaped bottom plate preparation step is used to prepare the patterned aluminum plate into a Z-shaped bottom plate. The riveting step of the mouth-shaped coaming is used to riv...

Abstract

The invention discloses a method for preparing a freezer liner in front of glue application, which sequentially comprises the preparation of a U-shaped large enclosure, the preparation of a U-shaped small enclosure, the preparation of a Z-shaped bottom panel, the riveting of a mouth-shaped enclosure, and the beating of corners Glue, riveting of the bottom plate of the hoarding, side punching, and gluing of the riveting line. The riveting of the bottom plate of the coaming includes pre-riveting of the bottom plate, riveting of four rounded corners, synchronous riveting of the vertical edge and edge, synchronous riveting of the side edge and edge and step-by-step riveting of the short side. Bottom plate pre-riveting performs synchronous riveting on multiple points selected on the corner line where the Z-shaped bottom plate and the mouth-shaped coaming are combined. Four rounded corners are riveted in two steps for four rounded corners. The synchronous riveting of the vertical side and the end side performs synchronous riveting on the two vertical corner lines and the high-end corner line. Side edge synchronous riveting performs synchronous riveting on two long side corner lines and low end corner lines. Short side step-by-step riveting Rivets two short side angle lines step by step. The method is convenient for automatic production equipment to realize automatic production.

Description

technical field [0001] The invention relates to a liner production line for a refrigerator. 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 coamings and the Z-shaped bottom plate is done manually, and there is no fully automated refrigerator liner production line. Contents of the invention [0003] The problem to be solved by the present invention: the ...
