A copper tungsten arc gouging device

Abstract

The invention belongs to the field of mechanical processing, and in particular relates to a copper-tungsten arc gouging device. Copper tungsten arc gouging device, including: tungsten electrode head, copper pipe body, separator, water inlet pipe, water outlet pipe; Inner hole; the copper tube body is a cylindrical shell with a closed upper end and an open lower end, and the lower end of the copper tube body is fixedly connected with the cylinder of the tungsten electrode head; a partition is arranged inside the copper tube body along the axial direction of the copper tube body, and the partition The copper pipe body is divided into a water inlet chamber and a water outlet chamber along the axial direction of the copper pipe body. The closed end of the copper pipe body is provided with a water inlet pipe and a water outlet pipe. The water inlet pipe is connected with the water inlet chamber, and the water outlet pipe is connected with the water outlet chamber. The present invention is simple in structure, easy to use, the connection between the copper tube body and the tungsten electrode head is firm, and a water circulation system is provided inside, which is easy to reduce heat; the discharge of the tungsten electrode head is adopted, the arc is stable, the incision groove is formed flat, and it is beneficial to the process of root cleaning and the like. Achieve mechanization.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a copper-tungsten arc gouging device, which is used for the work of gouging, eliminating welding defects, removing welding roots and the like in welding production. Background technique [0002] At present, most of the gouging devices on the market are carbon arc gouging devices. The carbon rod in the carbon arc gouging device is a loss electrode. Carbon arc gouging has the following disadvantages: [0003] 1. Carbon rods wear out quickly and have a short life cycle; [0004] 2. It needs to be replaced after consumption to reduce production efficiency, which is time-consuming and laborious; [0005] 3. The loss of carbon rod electrodes produces a lot of smoke and dust, which greatly deteriorates working conditions and pollutes the environment; [0006] 4. The arc formed by the carbon rod electrode is unstable, and the technical requirements for the operator are ...
