Full-aluminum alloy material van carriage and manufacturing process

Abstract

The invention discloses a full-aluminum alloy material van carriage and a manufacturing process thereof. The all-aluminum alloy material van carriage comprises a bottom plate assembly, a top plate assembly, a left side plate assembly, a right side plate assembly, a rear door assembly and a front side plate assembly; each sub-assembly is processed separately to form a modular unit, and finally assembly molding of the carriage is completed on the assembly line; the whole frame of the carriage adopts a 6063T6 material aluminum alloy extruded profile, the profile is machined through milling and stamping by a special die to achieve the required state of assembling; assembling of the carriage frame adopts the assembly process of BOOM structure rivet riveting, argon arc welding and bolt connection combination to obtain a frame structure with high strength and good stability; a panel structure of the carriage adopts a 5052 material high-strength aluminum alloy single-layer plate, and the plateis manufactured through a sheet metal machining process such as blanking, punching, bending, argon welding, grinding and the like; and high-gloss powder spraying treatment is adopted on the outer surface of the whole carriage. According to the van carriage and the manufacturing process, the purpose of lightweight of the vehicle body is achieved by adopting the all-aluminum alloy material.

Description

technical field [0001] The invention relates to an all-aluminum van-type truck compartment and a manufacturing process, belonging to the technical field of logistics equipment. Background technique [0002] The global shortage of oil and energy is becoming more and more serious, so the country is currently vigorously supporting the development of pure electric new energy logistics vehicles, passenger vehicles and other related industries. Electric vans need to carry larger and heavier battery packs, so there is a strong demand for weight reduction of the body. Lower body weight means better mileage performance. Therefore, major domestic manufacturers are developing low-density vehicles. Aluminum and aluminum alloys are more and more used in car body manufacturing due to their excellent properties such as high strength, low density, good weldability, and corrosion resistance. [0003] At present, the compartments of vans are still mainly made of steel, and there are also van...

AI Technical Summary

Problems solved by technology

[0003] At present, the compartments of vans are still mainly made of steel, and there are also van compartments made of composite materials such as fiberboards and honeycomb panels. If pure electric vans continue to use steel compartments, first of all, the weight reduction cannot be achieved. Demand will greatly affect the cruising range of pure electric trucks. On the other hand, the steel carriages are prone to corrosion after long-term exposure to the sun, wind and rain. Damaged carriages are expensive to maintain and have low recycling value.

Although the overall weight of the composite material carriage has a certain decrease compared with the steel carriage, the purpose of weight reduction can be achieved, but the overall strength of the composite material carriage is weaker than that of the steel carriage, and it is more difficult to repair if it is damaged.
