Device and method for reducing edge breakage of hole machining of brittle materials

Abstract

The invention discloses a device and a method for reducing edge breakage of hole machining of brittle materials. The device for reducing the edge breakage of hole machining of the brittle materials is characterized by comprising a machining platform, a heating table and a high-melting-point metal plate, wherein a space for containing a low-melting-point alloy is formed in the machining platform, the space is provided with an opening located on the upper end face of the machining platform, a plurality of threaded holes which are located in the upper end surface of the machining platform are formed in the circumferential direction of the opening; the heating table is located in the space and can move towards the opening; and the high-melting-point metal plate is located at the upper end of the heating table and can be heated by the heating table, and the circumferential direction of the high-melting-point metal plate is in sliding sealing with the inner wall of the space. According to the device for reducing the edge breakage of hole machining of the brittle materials, the heating table repeatedly heats the device, so that the low-melting-point alloy below a workpiece is repeatedly restored to a plane state, a lifting mechanism is matched with the lower surface of the workpiece, so that the effect of protecting the workpiece is achieved, the machining efficiency is improved, and materials are saved.

Description

technical field [0001] The invention relates to the field of hole processing, in particular to a device and method for reducing chipping of holes made of brittle materials. Background technique [0002] With the rapid development of aerospace and other fields, the requirements for the strength and hardness of materials are getting higher and higher, so some high-performance materials are gradually being applied, but some high-performance ceramics (such as Guo Jingkun. About the brittleness of ceramic materials [J ].Journal of Fudan University (Natural Science Edition), 2003,42(6):822-827.), alloys (such as Wang Yingmin, Qiang Jianbing, Geng Yaoxiang, etal. An iron-based amorphous soft magnetic alloy material and its preparation method) etc. have obvious brittleness. Bolt connection and rivet connection are the most commonly used connection methods for mechanical components, and both of these processing methods require hole processing for parts. When processing brittle mate...
