Accurate powder-adding device of flux-cored wire

Abstract

The invention discloses an accurate powder-adding device of a flux-cored wire. The accurate powder-adding device of the flux-cored wire comprises a device main body and an upper cover plate; the uppercover plate is arranged above the device body; the upper cover plate is welded on the device body; a motor is arranged below the upper cover plate; the motor is fixedly connected with the upper coverplate; a material tank is arranged in the device body; the material tank is fixedly connected with the internal part of the device body; a fixed grinding disk is arranged on the material tank; and the fixed grinding disk is fixedly connected with the material tank. According to the accurate powder-adding device of the flux-cored wire, a rotatable grinding disk is provided and is rotatably connected with the motor, damping devices area arranged on the two sides of the rotatable grinding disk, a vibration device is arranged on the right side of a filtering net, the rotatable grinding disk pulverizes material particles under the action of the motor to enable the materials to be refined, and the filtering net generates vibration under the action of the vibration device and further filters thematerials to enable the materials to be refined, so the problem that the materials have different volume and size is solved.

Description

technical field [0001] The invention relates to the technical field of powder adding devices, in particular to a precise powder adding device for flux-cored welding wire. Background technique [0002] The so-called flux-cored welding wire is also called tubular welding wire or welding material for various purposes (wear-resistant, high-strength, heat-resistant, corrosion-resistant, low-temperature resistance, etc.) , because its alloy composition can be adjusted flexibly and conveniently, so many varieties of flux cored wire cannot be smelted and rolled by solid wire. At the same time, due to the characteristics of the product structure, the welding process performance and welding efficiency of flux-cored welding wire have advantages compared with solid-cored welding wire and manual welding rod. [0003] However, the existing flux-cored wire powder adding equipment usually mixes the powder directly and then stirs the powder in the powder production process, and then adds th...

Problems solved by technology

[0003] However, the existing flux-cored wire powder adding equipment usually mixes the powder directly and then stirs the powder in the powder production process, and then adds the powder to the welding wire shell, which cannot accurately control the quality of the powder. At the same time, due to the Too much mixture of ingredients can easily cause agglomeration, resulting in flaws in the production of welding wire, and poor quality when used
