本发明提供了一种螺旋态药芯钎料饼的制备方法及其装置，包括一种螺旋态药芯钎料饼的制备方法，它包括以下步骤：步骤一、将钎剂配制成膏状备用；步骤二、将钎料轧制成窄带状空心结构；步骤三、将步骤一配制的膏状钎剂注入步骤二中的窄带状空心结构的钎料芯部，干燥后即可得到窄带状药芯钎料；步骤四、将步骤三中得到的窄带状药芯钎料盘绕成螺旋态药芯钎料饼；该螺旋态药芯钎料饼可实现钎剂精确定量添加，降低钎焊过程中钎剂用量，减少对环境的污染；使用时不用另加钎剂，大大提高了生产效率，降低了生产成本。

The invention provides a preparation method and a device of a spiral state flux-cored wire brazing filler metal cake. The preparation method of the spiral state flux-cored wire brazing filler metal cake comprises the following steps that firstly, soldering flux is prepared into paste for standby application; secondly, brazing filler metal is rolled into a narrow-strip-shaped hollow structure; thirdly, the paste soldering flux prepared in the first step is injected into a core part of the brazing filler metal of the narrow-strip-shaped hollow structure, and the narrow-strip-shaped flux-cored wire brazing filler metal can be obtained after drying; and fourthly, the narrow-strip-shaped flux-cored wire brazing filler metal obtained in the third step is coiled into the spiral state flux-cored wire brazing filler metal cake. By means of the spiral state flux-cored wire brazing filler metal cake, accurate and quantified adding of the soldering flux can be achieved, the using amount of the soldering flux in the brazing process is reduced, and the environment pollution is reduced; and in the using process, the soldering flux does not need to be additionally arranged, the production efficiency is greatly improved, and the production cost is reduced.
