All-sealed corrugated board carriage

Abstract

The invention provides an all-sealed corrugated board carriage. The all-sealed corrugated board carriage comprises a corrugated board; the corrugated board and a side wall front stand column, and the corrugated board and a front wall stand column are respectively integrated as a whole through double bent components by joint suspension spot welding; the joint suspension spot welding is performed for the corrugated board, a right-angled inner buckle plate component and a side wall upper cross beam; the suspension spot welding is performed for a side wall at the external of the side wall upper cross beam as a whole; the corrugated board, a baseplate front cross beam and a front wall lower cross beam are integrated as a whole through labyrinth components and basesplates by joint suspension spot welding to finally form the all-sealed corrugated board carriage; and suspension spot welding sealant is laid among all components for joining the corrugated board. The structure uses multiple joint modes and suspension spot welding, so that the welding after joint has no welding lines; suspension points and welding points in joint are hidden in middle; and meanwhile, because of special periphery structure, rainwater cannot enter the welded carriage to achieve all-sealed effect, the all-sealed performance of the carriage is guaranteed, and the object safety in the carriage is guaranteed.

Description

technical field [0001] The invention relates to a compartment of an automobile, in particular to a fully sealed corrugated board compartment. Background technique [0002] With the rapid development of express delivery and other logistics industries, the demand for vans with good waterproof performance is increasing day by day. The compartments of vans are usually made of metal corrugated boards. The traditional corrugated boards are generally made of CO2 shielded welding process, because CO2 shielded welding has low investment cost and short production preparation period, which is suitable for small batch operations. When faced with the rapidly growing demand for vans, the traditional CO2 shielded welding process is not suitable for high-quality standard mass production line operations. [0003] Corrugated board carriages are usually made of CO2 shielded welding process. Although CO2 shielded welding has the advantages of small investment and short production preparation p...

Problems solved by technology

[0004] The production efficiency is low, and it is difficult to achieve high-efficiency operations in large quantities; the surface quality of CO2 shielded welding is very poor, and defects such as deformation, burn-through, and weld bumps are very easy to occur; the welding strength of thin plates of CO2 shielded welding is unreliable; the dimensional accuracy of CO2 shielded welding is stable bad sex;

[0005] The waterproof performance of CO2 shielded welding thin plate welding process is unreliable
