Title:
ULTRASONIC MICRO-FORGING COMBINED APPARATUS FOR IMPROVING STRUCTURE AND PERFORMANCE OF ADDITIVE MANUFACTURED METAL AND ADDITIVE MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/037338
Kind Code:
A1
Abstract:
Disclosed are an ultrasonic micro-forging combined apparatus for improving structure and performance of additive manufactured metal and an additive manufacturing method. The apparatus comprises a transducer (11), a pneumatic sliding bench (4), a pneumatic sliding bench connection frame (5), a variable-amplitude rod (10), a tool head (8) and a roller (6), wherein the transducer (11) is provided in a transducer housing (3), an insertion member (1) and a pipeline connector (2) are provided on the transducer housing (3), the variable-amplitude rod (10) is connected under the transducer (11), the tool head (8) is connected under the transducer (11), the roller (6) is located between the tool head (8) and a workpiece (7), and the pneumatic sliding bench (4) is connected to the transducer housing (3) and the variable-amplitude rod (10) via the pneumatic sliding bench connection frame (5). The ultrasonic micro-forging combined apparatus combines the advantages of high ultrasonic impact frequency and great deformation produced by mechanical rolling, can realise the combined action of ultrasonic impact and continuous rolling micro-forging, realising the aims of improving the microcosmic structure of additive manufactured metal and the physical performance of components and parts. By organically combining with the existing additive manufacturing technology, the technical bottleneck of being easy to control shape but difficult to control properties in the existing metal additive manufacturing are solved.
