The invention discloses a vane wheel piece dropping distressing laser impact forging remanufacturing method. In the machining process, a pulse laser head remains motionless; and a workpiece, a coaxialpowder feeder and a water spray head are driven by a multi-freedom-degree machine arm, so that a space track which meets the complex hook face shape and is used for repairing, reinforcing and reshaping a vane wheel is obtained. The invention further discloses a device adopting the vane wheel piece dropping distressing laser impact forging remanufacturing method. According to the vane wheel remanufacturing method, the technological process integrating repair, reinforcing and reshaping is adopted, and laser forging for reinforcing can be conducted while a vane wheel piece dropping area is repaired; the vane wheel shape is resumed; and comprehensive mechanical performance of the remanufactured vane wheel is improved.
Description
technical field [0001] The invention relates to the technical field of remanufacturing, in particular to a laser shock forging remanufacturing method and device for removing stress from impeller blocks. Background technique [0002] The impeller is a key component of an aero-engine. The integral impeller blank is generally a whole forging, so the machining allowance is large and the material removal rate is high. The material is usually made of titanium alloy or high-temperature alloy and other difficult-to-machine metal materials. In addition, the impeller blade is a curved surface with complex distortion in space, complex structure, and thin blade wall thickness, so deformation and knife gap phenomenon are prone to occur during processing, blade processing is prone to distortion, the channel opening is poor, and the accuracy requirements are relatively high. high. Therefore, the processing and manufacturing efficiency of the impeller is low, the cycle time is long and the...
