Abstract

The invention relates to a gantry-type structural part and its additive manufacturing method. The gantry-type structural part is provided with a large number of weight-reducing holes, thereby reducing the self-weight of the gantry-type structural part and increasing the stiffness-to-weight ratio of the gantry-type structural part. Using the additive manufacturing method provided by the present invention to produce the gantry structure can simplify the production process of the gantry structure and improve the quality of the gantry structure.

Description

technical field [0001] The invention belongs to the technical field of additive manufacturing, and in particular relates to a gantry structure and an additive manufacturing method thereof. Background technique [0002] Gantry structural parts are widely used in CNC machine tools, testing equipment and other fields, and the quality of gantry structural parts directly affects the performance of these devices. [0003] Existing gantry-type structural parts are generally manufactured by welding or casting. When welding is used to manufacture gantry-type structural parts, dozens or hundreds of plates need to be welded. The welds are long and the deformation of the welds is not easy to control; while casting In this way, it is necessary to equip molds according to different gantry-type structural parts, but the cost of the mold itself is high, and the dimensional accuracy of the mold is not good, and the casting time is long. That is to say, there is a problem that the quality of...
