Abstract

The invention discloses a water tank of a diesel engine. The water tank of the diesel engine comprises a connecting stud, and a water tank upper cover, a water tank middle body and an upper welding plate which are subjected to drawing and stamping forming, wherein the water tank upper cover is welded at the opening of the upper end of the water tank middle body; the upper welding plate is welded on the water tank upper cover; and the connecting stud is welded on one side of the water tank upper cover and the water tank middle body. In the water tank of the diesel engine, the water tank upper cover, the water tank middle body and the upper welding plate have the drawing and stamping forming structure, and the stud, the water tank upper cover, the water tank middle body and the upper welding plate are welded together to form the water tank of the diesel engine. The water tank of the diesel engine are divided into a plurality of parts which are subjected to drawing forming sequentially, so the defects of cold shut, sand burning, uneven outer surface and the like caused by casting are overcome. The water tank of the diesel engine has a bright and clean surface, does not have sand hole leakage, does not require procedures of sanding, polishing and the like, saves materials, and has high production efficiency and shock strength higher than that of products produced by a casting process.

Description

technical field [0001] The invention relates to the technical field of water tanks, in particular to a diesel engine water tank. Background technique [0002] The water tank is one of the indispensable devices of the water-cooled diesel engine. Most of the traditional water tanks are made of casting technology, which is prone to cold insulation, sticky sand, uneven outer surface defects, high energy consumption of materials, and easy to be broken during use. Cold septums are pierced or impenetrable gaps in the casting with rounded edges. Cracks or fractures appear in the cast workpiece after being subjected to a certain force, and oxide inclusions appear in the fracture, or they are not fused together. Cold barriers mostly appear on the wide upper surface or thin wall far away from the gate, where the metal flow meets, and the chilling parts such as cold iron and core support. [0003] In order to reduce the defects of traditional casting water tanks, the existing technolo...
