A wire electrode fixing device

Abstract

The invention discloses a linear electrode fixing device. The linear electrode fixing device comprises a main body support frame, a resistance conversion module and an automatic stringing module, wherein the resistance conversion module is used for converting a static friction force generated by an electrode tightly attached onto a fixing frame at a corner to a sliding friction force between a pulley body and a bearing, the friction force between a linear electrode and the fixed frame is substantially reduced, and the problem that tightness of the linear electrode in the whole electrode fixing frame is not uniform in distribution is greatly solved; moreover, the resistance conversion module can slide in a sliding groove so as to adjust distance between lines, and the adaptability of electrode fixing frame is effectively improved; and by employing the automatic stringing module to apply a continuously-adjustable tension force onto a tail end of the linear electrode, the tightness of the linear electrode can be automatically adjusted, so that the linear electrode is difficult to loosen with time, and the discharge stability of the linear electrode is improved.

Description

technical field [0001] The invention belongs to the technical field of corona discharge, and more specifically relates to a wire electrode fixing device. Background technique [0002] The structure of the corona discharge electrode plays a very important role in the generation efficiency of charged particles. According to the classification of discharge type, the electrode structure can be divided into unipolar discharge electrode structure and bipolar discharge electrode structure. According to the shape of the electrode, the structure of the unipolar discharge electrode is mainly divided into various forms such as wire-barrel, wire-plate, needle-plate, and nozzle-type electrode structure evolved from needle-plate. According to the electrode shape, the bipolar discharge electrode structure is mainly divided into needle-needle structure and line-line structure. Comparing the unipolar and bipolar discharge electrode structures, under the condition of applying the same volta...
