Problems solved by technology

The realization methods of material surface nanometerization include shot peening, rolling, etc., but these methods will not only refine the surface grain of the material, but also increase the surface roughness of the part, thus limiting its application.
[0003] The nanometerization of the material surface is a new technology that has appeared in recent years. The Chinese patent application number is 99122670.4. Impact, low processing efficiency, not suitable for processing flat surfaces
The Chinese patent application number is 02109696.1. This invention discloses the use of high-pressure liquid to drive the solid-liquid two-way jet to bombard the metal surface to make it nano-sized, shot peening, rolling and other methods. However, these methods refine the surface grains of the material. It will also increase the surface roughness of the part, thus greatly limiting its application

Abstract

The invention provides a single-impact surface nano-crystallization and gradient structure machining device. The device comprises a tool head, a guiding sleeve, a transmission rod, a corrugated wear-resistant sleeve, wear-resistant balls, a pneumatic motor and a casing and can be manufactured in such a form that the device can be conveniently clamped on machining equipment such as a lathe, a milling machine, a planing machine, a grinding machine, a machining center and the like, the surface of a workpiece is subjected to plastic deformation, and surface grains are refined to the nanometer scale. With the device, the production efficiency can be remarkably improved, the equipment input can be reduced, the production cost can be reduced, and the surface performance and the overall performance of the workpiece can be improved.

Description

technical field [0001] The invention relates to the field of material processing engineering, in particular to a single-impact surface nanometerization and gradient structure processing device. Background technique [0002] The nanometerization of the material surface can significantly improve the fatigue strength, wear resistance, hardness, etc. of the surface layer of the material (or its parts), thereby improving the overall performance and service life of the material. The realization methods of material surface nanometerization include shot blasting, rolling, etc., but these methods can improve the surface roughness of the parts while refining the surface grains of the material, thus limiting their application. [0003] The nanometerization of the material surface is a new technology that has appeared in recent years. The Chinese patent application number 99122670.4 discloses that the invention uses an ultrasonic transducer to impact the hard ball on the surface of the ...
