Plasma electrode hafnium filament brazing device and brazing method

Abstract

The present invention discloses a plasma electrode hafnium filament brazing device, comprising an electrode body and a fixing member, wherein the electrode body is installed in a fixing sleeve, a cooling cover is sleeved at one lower end of the fixing sleeve, and a cooling water circulation chamber is formed therebetween; a second open pore is provided with a hafnium filament; an external threaded cylinder is screwed to the second open pore, and the lower end of the hafnium filament is inserted into the external threaded cylinder; the clamping structure comprises an upper sliding plate and a sliding plate slidably connected in the external threaded cylinder, and a spring connects the upper sliding plate with the sliding plate. The hafnium filament disclosed by the present invention has firm fastening, preventing the electrode body from softening due to increasing temperature, so that meet with the expected use strength; the height of the clamping structure in the external threaded cylinder can be adjusted by rotating a bolt to meet the different lengths of the hafnium filament; cooling water continuously flows in the cooling water circulation chamber to cool the electrode body, thereby improving the service life of the electrode body.

Description

technical field [0001] The invention belongs to the technical field of plasma electrode hafnium wire brazing equipment, and in particular relates to plasma electrode hafnium wire brazing equipment and a brazing method thereof. Background technique [0002] During the brazing process of the plasma electrode hafnium wire, the copper material of the electrode will become soft due to the temperature rise, so that it cannot reach the use strength. Therefore, we propose a plasma electrode hafnium wire brazing equipment and its brazing method to solve the problem. The problems mentioned in the background art above. Contents of the invention [0003] The object of the present invention is to provide a plasma electrode hafnium wire brazing equipment and a brazing method thereof, so as to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a plasma el...
