Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of flux-cored wire production and processing, in particular to a powder pressing device for zinc-aluminum flux-cored wire processing. BACKGROUND

[0002] Zinc-aluminum flux-cored wire is a special welding material, mainly composed of zinc and aluminum and other metal elements, and non-corrosive fluoride flux. This welding wire performs well in the welding of aluminum alloy and copper alloy. Its brazing process, joint mechanical properties and joint conductivity are superior to traditional zinc-cadmium, zinc-tin copper brazing filler metal. The advantage of zinc-aluminum flux-cored wire lies in its environmental protection, convenience and safety. It does not require special welding equipment and special production site, and can achieve high-quality welding.

[0003] The core is actually a mixture of multiple components, which may contain fluoride flux, alloy elements, active agents and other additives. Its main purpose is to provide necessary chemical and physical effects during the welding process to improve the quality and performance of the welded joint. The production process of flux-cored wire is to roll zinc-aluminum alloy into a strip shape first, then roll it into a U-shaped cross-section shape, then inject the mixed powder into the U-shaped alloy strip, and then roll it into an O-shaped shape. Finally, it is stretched into a finished product according to the requirements.

[0004] Therefore, during this period, the addition process of the powder is particularly important. At present, during the processing of flux-cored wire, the powder is injected into the U-shaped alloy strip by manually operating the equipment. Too much injection will cause accumulation, and the surface of the alloy strip is easy to be damaged, which will affect the quality of the finished product. Too little injection is not convenient for subsequent compaction operation, and air holes and other problems are easy to occur during welding.

[0005] Therefore, the present application is proposed. UTILITY MODEL CONTENTS
