Refrigerator inner container manufacturing method with glue application being conducted before riveting

Abstract

The invention discloses a refrigerator inner container manufacturing method with glue application being conducted before riveting. The refrigerator inner container manufacturing method with glue application being conducted before riveting sequentially comprises the steps of manufacturing a U-shaped large surrounding plate, manufacturing a U-shaped small surrounding plate, manufacturing a Z-shapedbase plate, riveting a square surrounding plate, conduct glue application on corner and edge lines, riveting the surrounding plate and the base plate, punching holes on side faces and conducting glueapplication on riveting lines. The step of riveting the surrounding plate and the base plate comprises the procedures of base plate pre-riveting, four-filleted-corner riveting, vertical edge and end edge synchronous riveting, side edge and end edge synchronous riveting and short side edge step-by-step riveting; according to base plate pre-riveting, synchronous riveting is conducted on multiple selected point locations on the combined corner and edge lines of the Z-shaped base plate and the square surrounding plate; according to the four-filleted-corner riveting, four filleted corners are riveted in two steps; according to vertical edge and end edge synchronous riveting, synchronous riveting is conducted on two vertical edge and corner lines and high end edge and corner lines; according tothe side edge and end edge synchronous riveting, synchronous riveting is conducted on two long side edge and corner lines and low end edge and corner lines. According to short side edge step-by-step riveting, riveting of two short side edge and corner lines is conducted step by step. By the adoption of the refrigerator inner container manufacturing method with glue application being conducted before riveting, an automatic production device can conveniently achieve 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 ...
