Example Embodiment

[0010] In the drawings, the impeller of the combined welded water pump of the present invention is welded by a hub 7, a reinforcing plate 6 and a plurality of impeller lobes 8; each of the impeller lobes 8 is composed of a rear cover plate 3, a blade 2, and a front cover plate. The flap 1 is composed of the rear cover flap 3, the blades 2, and the front cover flap 1 by a plate stamped on a special die to form a solid impeller flap 8; the edge line of each rear cover flap 3 and the other rear cover flap After the blades and the back cover flaps meet at the intersection line, the rear weld 4 is formed. The edge line of each front cover flap and the other front cover flap’s blade and the front cover flap meet at the intersection line to form the front weld 5. On the outside of the welding seam, each impeller lobe 8 is welded into a whole with a welding rod, and then the hub 7 and the reinforcing plate 6 are welded to obtain the welded impeller of the present invention.

Abstract

The invention discloses a combined welding type water pump impeller and a forming method thereof. The combined welding type water pump impeller is formed by welding a hub, a reinforcing plate and a plurality of impeller flaps; each impeller flap which consists of a rear cover plate flap, a blade and a front cover plate flap is stamped on one plate by using a die; the intersecting lines between the edge line of each rear cover plate flap and the rear cover plate flap as well as between the blade of another rear cover plate flap and the rear cover plate flap are abutted to form a rear welding seam; the intersecting lines between the edge line of each front cover plate flap and the front cover plate flap as well as between the blade of another front cover plate flap and the front cover plate flap are abutted to form a front welding seam; and all the impeller flaps are welded into a whole at the outer sides of the welding seams, and then the hub and the reinforcing plate are welded, therefore the combined welding type water pump impeller can be obtained. According to the combined welding type water pump impeller, the welding seams are formed outside the impeller, so that the welding operation is easily implemented, and no weld beading is generated in a runner. Therefore, the combined welding type water pump impeller is simple to form by welding, the blades are not deformed, the runner is free of resistance, and the technical level and working efficiency of a water pump are improved.

Description

1. Technical field [0001] The invention relates to a welded impeller and its forming method, in particular to a combined welded water pump impeller and its forming method. 2. Background technology [0002] At present, the impellers used in water pumps mainly include cast impellers and welded impellers. The casting impeller has high strength and small dimensional error, but the disadvantages are that there are many consumables, heavy weight, and the rough flow path hinders the water flow. The welded impeller is welded by plates, which has the advantages of light weight, less consumables, corrosion resistance, relatively smooth flow path, and long service life. The structure of the welded impeller currently used is composed of a rear cover plate, a front cover plate and multiple arc-shaped blades. The welding method is to weld multiple arc-shaped blades evenly on the rear cover plate, and then weld The cover plate is welded and fixed to the arc-shaped blade. The structure o...
