Thinning and electrolytic machining device for inner wall of static cutter cover of shaver and machining process method of device

Abstract

The invention relates to a thinning and electrolytic machining device for the inner wall of a static cutter cover of a shaver and a machining process method of the device and belongs to the technical field of machining of the static cutter cover of the shaver. The thinning and electrolytic machining device is based on an electrolytic machining principle and adopts a tool cathode to carry out thinning and machining forming on the inner wall of a blank of the static cutter cover; and in the process of carrying out electrolytic machining on the blank of the static cutter cover, the blank of the static cutter cover rotates around the axis of the blank of the static cutter cover when linearly fed relative to the tool cathode, and electrolyte required for the electrolytic machining flows through a machining gap formed by the blank of the static cutter cover and the tool cathode continuously at a high speed (10 m / s to 20 m / s). The thinning and electrolytic machining device not only has a high machining efficiency, a stable machining process and a high accuracy, but also realizes high-quality and high-efficiency machining on the inner wall of the static cutter cover.

Description

technical field [0001] The invention relates to an electrolytic processing device for thinning the inner wall of a razor static knife cover and a processing method thereof, and belongs to the technical field of mechanical processing of the razor static knife cover. Background technique [0002] With the development and research of new technologies, new materials and new processes, in the razor industry, the processing of static knife caps has become an urgent need for improvement and research. In order to make the hair fully enter the shearing area where the static knife cover and the moving blade cooperate and ensure the strength and rigidity of the static knife cover, the wall thickness of the static knife cover is usually reduced to about 0.1mm; in order to reduce the wear and tear of the moving blade and increase its service life , The inner wall of the static knife cover should ensure high surface quality. [0003] At present, in order to ensure the high surface qualit...

AI Technical Summary

Problems solved by technology

[0006] Due to the complex structure of the inner wall of the static knife cover, the flow field in the machining gap is unevenly distributed by the above-mentioned machining method, and flow marks are easily generated on the inner wall surface. With the increase of the tool cathode feed depth, the flow field conditions in the machining gap further deteriorate, and local areas lack liquid, eventually leading to the occurrence of short circuit phenomenon
