Description

TECHNICAL FIELD

[0001] The present application relates to the field of metal material processing and manufacturing, and particularly relates to a production method for assembling a cable reel made of recycled aluminum. BACKGROUND

[0002] Recycled aluminum, also known as secondary aluminum, is obtained by smelting waste aluminum parts and waste aluminum materials. At present, the annual production of recycled aluminum in the world is about 4 million tons, accounting for a considerable share of the production of primary aluminum. The recycling of recycled aluminum can reduce the destruction of land vegetation and consume only about 5% of the energy of electrolytic aluminum production, and is increasingly valued. However, in the process of recycling and remelting, the impurities in recycled aluminum are relatively high, and in order to ensure the performance of the products produced by recycled aluminum, purification and impurity removal in the smelting and casting of recycled aluminum are particularly important.

[0003] The cable reel is also called cable tray, cable tray, cable reel, etc. Its structure is a disc type, the cable is wound on the outer edge of the disc, and the core of the reel is a shaft hole which can be inserted into the shaft after the reel is erected to realize free rotation and gradually extend the cable. The structure is simple and durable. The traditional cable reel is made of steel-wood composite material or steel. The angle steel roller is bent into a circular frame, the joints are welded and fixed, and then the circular frame and the spokes are welded together. The flat part of the reel is usually filled with a wooden board.

[0004] Although the traditional cable reel has low manufacturing cost, it still has the following shortcomings: 1. The part filled with wood board of the cable reel needs to use a large amount of wood, which does not meet the concept of environmental protection. The wooden board is also prone to rot in outdoor environment, affecting the service life; 2. The use of steel frame makes the overall weight of the cable reel heavier, which is not convenient during transportation and handling, and consumes more manpower, material resources and energy; 3. The repair of the cable reel is relatively complex and costly after damage, so if the damage is serious, the whole is scrapped, and the residual value is low; 4. The cable reel needs to occupy a large space for storage when it is idle, which is not conducive to reducing the storage cost.

[0008] Although some cable reels made of aluminum alloy are introduced in the existing documents, there are still some shortcomings, such as low aluminum content, insufficient overall structural stability, and inconvenient disassembly. Moreover, the existing aluminum alloy reels still use welding structures in whole or in part, and the welding structure will cause annealing phenomenon at the aluminum alloy connecting nodes, resulting in serious local strength reduction and affecting the overall strength of the reel. SUMMARY

Threaded holes are provided on the side surface of the embedded block, and the bolts pass through the through holes of the spoke to fix the spoke close to the reel profile.

[0014] The outer disc holder profile is obtained by roll bending or press bending.
