Embodiment Construction
[0024] The shot blasting strengthening method of engine blades, the special features of this method are:
[0025] Select the first type of steel shot with a particle size of 1 mm, the second type of steel shot with a particle size of 1.2 mm, the third type of steel shot with a particle size of 1.5 mm, the fourth type of steel shot with a particle size of 1.7 mm, and a particle size of 2 mm. Millimeters of the fifth steel shot are mixed evenly to form a mixed shot; wherein the first steel shot, the second steel shot, the third steel shot, the fourth steel shot, and the fifth steel shot respectively account for the total amount of the mixed shot 30%, 13%, 20%, 20%, 17% of the weight;
[0026] Throw the mixed shot through the cylindrical tubular blade of the shot blaster at a speed of 63.5m / s, and then hit the engine blade for 30s;
[0027] Then throw it at a speed of 70m / s, and hit the engine blade for 20s;
[0028] Then throw it at a speed of 72m / s, and hit the engine blade f...

Abstract
The invention discloses a blasting strengthening device and a shot blasting strengthening method for engine blades. The strengthening method comprises the following steps: evenly mixing five steel shots, of which the grain sizes are 1mm, 1.2mm, 1.5mm, 1.7mm and 2mm, so as to form a mixed shot material, wherein the five steel shots respectively account for 30%, 13%, 20%, 20% and 17% of the total weight of the mixed shot material; respectively blasting the mixed shot material for 30 seconds, 20 seconds, 30 seconds, 40 seconds and 30 seconds through cylindrical tube blades of an impeller head at speeds of 63.5m/s, 70m/s, 72m/s, 75m/s and 80m/s. The used impeller head is characterized in that the blades is in a shape of a cylindrical tube; arc grooves are formed in the outer surfaces of the blades; the axes of the arc grooves are vertical to that of the blades; a plurality of cylindrical near impeller fixing rods and a plurality of cylindrical far impeller fixing rods are arranged between two discs of an impeller body of the impeller head, and matched with the grooves on the blades; a thin section is arranged at the end of each blade near the impeller; an outer conical surface is arranged at the tip of each thin section; the outer conical surfaces of two adjacent blades are tightly butted together. By adopting the method, the engine blades are cleaned more completely; the strengthening quality is higher; the device is used for achieving the method; the blades have less possibility of being abraded; the blasting strengthening device is simple and reliable to install.
Description
technical field [0001] The invention relates to a shot blasting strengthening method and a strengthening device of an engine blade. Background technique [0002] At present, the engine blades are all shot blasted by a shot blasting strengthening device. One is to clean the surface, and the other is to eliminate stress and achieve strengthening. However, the current shot blasting treatment method has incomplete cleaning and poor strengthening quality. advanced questions. Contents of the invention [0003] In order to overcome the shortcomings of the above-mentioned prior art, the object of the present invention is to provide a method for shot blasting engine blades, so that the engine blades can be cleaned more completely and the strengthening quality is higher. The special features of this method are: [0004] Select the first type of steel shot with a particle size of 1 mm, the second type of steel shot with a particle size of 1.2 mm, the third type of steel shot with a ...
