Copper tungsten arc gouging device

Abstract

The invention belongs to the field of machining and particularly relates to a copper tungsten arc gouging device. The copper tungsten arc gouging device comprises a tungsten electrode tip, a copper pipe body, a separation plate, a water inlet pipe and a water outlet pipe. The lower end of the tungsten electrode tip is a cone. The upper end of the tungsten electrode tip is a cylinder. A tungsten electrode tip inner hole is formed in the tungsten electrode tip in the axial direction. The copper pipe body is a cylindrical shell with the sealed upper end and the open lower end. The lower end of the copper pipe body is fixedly connected with the cylinder of the tungsten electrode tip. The separation plate is arranged in the copper pipe body in the axial direction of the copper pipe body. The copper pipe body is divided into a water inlet cavity and a water outlet cavity through the separation plate in the axial direction of the copper pipe body. The sealed end of the copper pipe body is provided with the water inlet pipe and the water outlet pipe. The water inlet pipe is connected with the water inlet cavity. The water outlet pipe is connected with the water outlet cavity. The copper tungsten arc gouging device is simple in structure and convenient to use, and the copper pipe body is firmly connected with the tungsten electrode tip. A water circulation system is arranged in the device, and cooling is easy; and the tungsten electrode tip is adopted for discharging, an electric arc is stable, a formed groove of a notch is level, and mechanization of the back gouging process and the like is facilitated.

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 ...
