Damage protective device and method used for aluminum alloy board transportation

Abstract

The invention discloses a damage protective device and method for aluminum alloy board transportation. The device comprises a net-shaped tray (1), protective assemblies and a fastening belt (6), wherein the aluminum alloy board (7) is stacked on the net-shaped tray through the fastening belt; the protective assemblies are arranged around the outer side of the aluminum alloy board in a peripheral mode; each protective assembly comprises a positioning rod (2), a limiting plate (3), an elastic body (4) and a plurality of regulating bolts (5); the positioning rods are inserted into the net-shapedtray; the limiting plates are embedded into the positioning rods; the regulating bolts are rotatably connected to the positioning rods, penetrate through the positioning rods and are inserted into thelimiting plates; and the elastic bodies are arranged on the limiting plates and fit to the outlines of the aluminum alloy boards; and the elastic bodies generate elastic deformation, and fit to the staggered edges of each layer of aluminum alloy boards. Concave and convex deformation of the elastic bodies is suitable for staggered edge difference of the stacked aluminum alloy boards, so that thealuminum alloy boards are ensured to not generate relative slide and friction among layers in a transportation process, and therefore, transportation damages are avoided, a board rejection rate is reduced, economic loss is reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to a transportation protection device and method for auto parts, in particular to a damage protection device and method for aluminum alloy plate transportation. Background technique [0002] Aluminum alloys have been widely used in the manufacture of body structural parts. Aluminum alloy flat plates are manufactured by uncoiling, blanking or cutting of aluminum coils, then stacked automatically or manually, and transported to the stamping factory for stamping. At present, most of the aluminum alloy plates for automobiles are made of 5 series aluminum-magnesium alloy or 6 series aluminum-magnesium alloy. The fluctuating control value of the textured surface roughness is within 0.15. [0003] Whether it is manual stacking or mechanical automatic stacking, it is inevitable that there will be misaligned edges when stacking aluminum alloy plates, which cannot be completely aligned, especially for irregularly shaped aluminum alloy pla...

Problems solved by technology

[0003] Whether it is manual stacking or mechanical automatic stacking, it is inevitable that there will be misaligned edges when stacking aluminum alloy plates, which cannot be completely aligned, especially for irregularly shaped aluminum alloy plates, with uneven edges and layers, which is inevitable during transportation The relative sliding or collision between layers due to bumps, vibrations or changes in acceleration and deceleration will cause the relative friction between two adjacent aluminum alloy plates to reciprocate at high frequency, causing the roughened surface between the metal and the metal to fall off, and Oxidation with the surrounding oil, air, etc. under the assistance of frictional heat to produce black spots, resulting in transportation damage

Usually there are a lot of black spots, the main component is alumina, and the spot diameter ranges from 0.1-2mm. They gather or disperse on the surface of the aluminum alloy plate, causing the aluminum alloy plate to fail the appearance inspection and scrap, which increases the production cost.

[0004] In order to avoid vibration, collision and relative sliding during transportation, the stacked aluminum alloy plates are usually fixed with ropes or the limit rod is placed on the outside of the plates to reduce horizontal sliding and up and down movement. However, due to the processing errors of the plates, The misalignment between layers caused by factors such as manual or mechanical stacking errors cannot be eliminated, and small sliding friction between layers is still unavoidable. The problem of plate scrapping caused by frequent friction during transportation has never been solved.
