Tungsten knife electrode polishing device

Abstract

The invention relates to the technical field of tungsten cutter electrode production and machining, in particular to a tungsten cutter electrode polishing device which comprises a U-shaped base, semicircular guide strips are fixedly mounted at the top ends of two supporting arms of the U-shaped base, arc-shaped through holes are formed in the semicircular guide strips, and polishing assemblies are slidably connected to the arc-shaped through holes of the semicircular guide strips. The grinding assembly comprises a sliding sleeve slidably connected to the arc-shaped through hole in the semicircular guide strip, a telescopic rod is arranged on the inner side of the sliding sleeve in a penetrating mode, and a pressing block and a first motor are fixedly installed at the top end and the bottom end of the telescopic rod correspondingly. In the actual use process, adaptive adjustment can be effectively conducted according to the tungsten cutter electrode, it is guaranteed that the electrode can be effectively and stably clamped and fixed in the polishing process, comprehensive and adjustable polishing treatment can be achieved, and the polishing effect is improved; and after polishing is completed, metal scraps generated in the polishing process can be effectively recycled, collection of rare metal is guaranteed, and resource waste is avoided.

Description

technical field [0001] The invention relates to the technical field of production and processing of tungsten knife electrodes, in particular to a grinding device for tungsten knife electrodes. Background technique [0002] Tungsten has a high melting point (3683°C±20°C), strong electron emission capability, high elastic modulus, and low vapor pressure, so it has been used as a thermal electron emission material for a long time. The emission efficiency of pure metal tungsten is very low, and recrystallization at high temperature forms an equiaxed grain structure, which makes the tungsten wire sag and break. In order to overcome the above shortcomings and adapt to the development of modern industrial new technologies and new processes, material workers from various countries are devoting themselves to the research and development of various new electrode materials. Doping some rare earth oxides with low electron work function based on tungsten can not only increase the recrys...

Problems solved by technology

[0004] In order to improve the adaptability of the existing tungsten knife electrodes in the process of production and processing, it is usually necessary to polish and polish the finished product. However, due to the different sizes and specifications of the tungsten knife electrodes, the existing The device cannot be properly clamped and fixed, and the grinding is not comprehensive enough, which affects the grinding effect. On the other hand, since tungsten is a rare metal, it is easy to cause waste of rare resources in the actual grinding process. Therefore, we propose a Tungsten knife electrode grinding device
