Abstract

The invention provides a rapid formation method of an X-ray detecting device for a blade of an aviation engine. The rapid formation method comprises the following steps: I, establishing a three-dimensional entity model of the X-ray detecting device according to the blade structure; II, slicing the model of the detecting device, and planning the laser scanning path of each layer; III, inputting the model on selective laser sintering equipment, setting the technological parameters of selective laser sintering, and adopting laser beams to scan powder material on each layer according to the planned scan path; IV, performing finishing treatment on the surface of a part after machining; V, enhancing the strength of a formed part; VI, after curing the part, removing the redundancy on the surface to obtain the X-ray detecting device. According to the rapid formation method, the technology is simple and easy to control, the operation is reliable, the production period is short, and the repeatability is high; the X-ray detecting device manufactured by adopting the rapid formation method is reliable in mechanical property, meets the operating requirements, and can realize rapid response manufacture according to different blade structures.

Description

technical field [0001] The invention relates to the technical field of rapid prototyping of non-metallic materials, in particular to a rapid prototyping method of an X-ray detection device for an aeroengine blade. Background technique [0002] At present, the blade X-ray inspection device is mainly completed by machining. Since the shape of the blade is mostly a complex curved surface, and there are many types, it is difficult or even impossible to manufacture a device structure that can fully match the blade shape, and the traditional method has a long processing cycle. , low material utilization. [0003] Traditionally, selective laser sintering technology is used. First, the three-dimensional model is converted into two-dimensional sheet information of a certain thickness, and then the laser scanning path of each layer is planned, and the laser beam is controlled to scan the scanning path, so that the powder materials are bonded to each other. , get the entity of this la...
