With the rapid development of the remanufacturing industry in the construction machinery industry, major manufacturers and agents have established their own remanufacturing bases and workshops. The following describes the excavator remanufacturing process flow.
1. Main frame welding repair work: Mainly to weld the replacement parts and repair areas of the main frame. The structural strength of the new welded joints fully meets the various stress conditions of the excavator. The welds of the new welded joints need to undergo flaw detection. After inspection, the safety and reliability of the welded joints are guaranteed.
2. Chassis welding repair work: It is mainly to weld the replacement parts and repair areas of the chassis. The structural strength of the newly welded joints fully meets the various stress conditions of the excavator. The welds of the newly welded joints need to undergo flaw detection. The safety and reliability of the welded joints after inspection are guaranteed.
3. Excavator body covers the repair and shaping area of sheet metal parts: relying on remanufacturing and efficient old machine recycling channels and the identification of professionals, repairing old parts that have been identified and have the possibility and value of repair, such as: cab sheet metal Parts, left and right side door components, battery box covers, partitions, etc. After refurbishment, grinding, drilling, polishing, etc., the old parts can glow with the effect of new parts.
4. Excavator special repair area: through remanufacturing efficient old machine recycling channels, after being identified by remanufacturing professionals, some of them have use value and can only be repaired in accordance with the overhaul standard to restore their use value. , It only takes a short time, and the various needs of customers can be met with the exquisite repairs of the professional remanufacturing team.
5. The main frame polishing and repairing operation: mainly to polish the repaired areas of the main frame, the consistency of the appearance of the polished repaired area is inherited, and the transition of each connection is natural and smooth, and it looks like the original car difference.
6. Main frame identification, plastic replacement and repair tooling: the main function is to identify, inspect and reshape the old and new main frames. It can also be used for replacement and reassembly of various parts. This tooling affects the shape of the main frame, boom and stick. The position change has the intuitive inspection result, and the product can be directly inspected after the plastic repair to ensure the repair quality of the product.
7. Chassis assembly and plastic repair tooling: the main function is to perform identification inspection and plastic repair of the old and new chassis. It can also be used for replacement and reassembly of various parts. This tooling has an intuitive inspection result for the changes in the shape and position of the chassis. After the repair, the product can be directly tested to ensure the quality of the repair.
