Damage protection device and method for aluminum alloy plate transportation

Abstract

The invention discloses a damage protection device and a method for transporting an aluminum alloy plate. The device comprises a mesh tray (1), a protection component and a fastening belt (6); the aluminum alloy plate (7) is stacked by the fastening belt Stacked on the mesh tray, several groups of protective components are circumferentially surrounded on the outside of the aluminum alloy plate; the protective components include a positioning rod (2), a limit plate (3), an elastic body (4) and several adjustment bolts (5); The positioning rod is inserted on the mesh tray, the limit plate is embedded in the positioning rod, the adjusting bolt is screwed with the positioning rod, and penetrates through the positioning rod and is inserted into the limit plate; the elastic body is arranged on the limit plate and fits together The outer contour of the aluminum alloy plate, the elastic body produces elastic deformation and fits the wrong side of each layer of the aluminum alloy plate. The invention can adapt to the misalignment of stacked aluminum alloy plates through the concave-convex deformation of the elastic body, ensure that the aluminum alloy plates do not have relative sliding and friction between layers during transportation, avoid transportation damage, reduce the scrap rate of plates, and reduce economic losses ,save costs.

Description

technical field [0001] The invention relates to a transportation protection device and method for automobile parts, in particular to a damage protection device and method for transportation of aluminum alloy plates. Background technique [0002] Aluminum alloys have been widely used in the manufacture of body structures. Aluminum alloy plates are made by uncoiling, blanking or cutting from aluminum coils, and then stacked automatically or manually, and transported to the stamping factory for stamping forming. 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 surface roughness fluctuation control value of texturing is within 0.15. [0003] Whether it is manual stacking or automatic mechanical stacking, it is inevitable that there will be misalignments when stacking aluminum alloy plates, which cannot be completely aligned, especially for aluminum alloy plates with irregular s...

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.
