Accurate powder-adding device of flux-cored wire

Abstract

The invention discloses a flux-cored wire precision powdering device, comprising a device body and an upper cover plate, an upper cover plate is arranged above the device body, the upper cover plate is welded on the device body, a motor is arranged under the upper cover plate, and the motor is fixed Connected to the upper cover plate, there is a material tank inside the device body, the material tank is fixedly connected in the device body, the material tank is provided with a fixed grinding disc, and the fixed grinding disc is fixedly connected to the material tank. This kind of flux-cored wire precision powdering device is equipped with a rotating grinding disc, and the rotating grinding disc is rotatably connected to the motor. Both sides of the rotating grinding disc are equipped with shock absorbing devices, and the right side of the filter screen is equipped with a vibration device. Next, the material particles are crushed to make the material finer, and then the filter screen vibrates under the action of the vibrating device, and the material is further filtered to make the material finer, which solves the problem of different sizes of the material.

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
