Abstract
The utility model relates to a gas shield device for impeller laser welding. The gas shield device for the impeller laser welding comprises a gas inlet, a fixing rod, a gas outlet, a gas distributing pipe and a protection cover, wherein the gas distributing pipe is evenly provided with a plurality of gas outlets, and an argon tube is connected in the gas inlet. The gas shield device for the impeller laser welding is capable of solving the problem that welding seams are oxidized in the cooling process in the welding process of impellers, reasonable in structure and convenient to use. In the welding process, the welding seams can be effectively protected against oxidation, and the cooling speed of the welding seams can be improved. Due to the impeller streamline simulation design of the protection cover, the welding seams can be protected for a long time, consumed argon is less, and the gas shield device for the impeller laser welding is affordable.
Description
Technical field
The utility model belongs to water pump vane welding field, is specifically related to a kind of gas shield device for impeller welding.
Background technology
Impeller is the heart of water pump; the quality of impeller is determining the performance of complete machine; in impeller welding process; due to heat affected area, to depart from gas shield center far away; the heat affected area of weld seam is the solid-state heating repeatedly of mother metal, and high-temperature residence time is longer, easily oxidized; heat affected area presents black and yellow, therefore needs welding high-temperature region to carry out gas shield.Existing laser welding apparatus, protection gas is only protected LASER HEATING place, and heat affected area is subject to comparatively serious oxidation.The purpose of this utility model, for the deficiency of existing equipment, provides a kind of impeller welding gas shield device, and its reasonable in design is easy for installation, and economical and efficient can effectively protect the heat affected area of weld seam not oxidized.
Summary of the invention
The technical solution of the utility model is: gas shield device is made up of air inlet, fixed bar, venthole, gas distribution pipe, protective cover; air inlet and gas distribution pipe are welded as a whole; air inlet is connected with tunger tube; fixed bar is welded on protective cover; fixed bar is fixed on protective device on laser head; gas distribution pipe upper end and two ends are evenly equipped with some ventholes, and gas distribution pipe and protective cover are threaded connection and are integrated.The invention solves the oxidized problem of weld heat-affected zone in impeller welding process, protective device is rational in infrastructure, manufacture install simple, the imitative Streamline Design of protective cover, economical and efficient, and can and impeller welding fixture be used in conjunction with.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is further detailed.Fig. 1 is the vertical cut-away schematic view of impeller laser weld gas shield device structure.Fig. 2 is the horizontal profile schematic diagram of impeller laser weld gas shield device structure.In figure, 1 is air inlet, and 2 is fixed bar, and 3 is venthole, and 4 is gas distribution pipe, and 5 is protective cover, 6 blade and front shroud intersections for welding impeller, and 7 is blade and back shroud intersection.
Detailed description of the invention
Fig. 1 is the structural representation of impeller laser weld gas shield device; as seen from the figure, air inlet 1 is welded as a whole with gas distribution pipe 4, and fixed bar 2 is welded as a whole with protective cover 5; gas distribution pipe 4 and protective cover 5 are threaded connection and are integrated, and fixed bar 2 is fixed on whole protective device on laser head.On gas distribution pipe 4, uniform some ventholes 3, make to protect gas to be uniformly distributed in protective cover, and protective cover is the streamlined of imitative impeller profile, can protect weld seam with maximum duration to greatest extent, and can be used in conjunction with welding impeller mold, protect respond well.
