本发明公开了一种圆形药芯钎料饼，该圆形药芯钎料饼由异形药芯银钎料盘绕成平面螺旋形，制备方法包括以下步骤：1、将钎料制备成药芯银钎料；2、将药芯银钎料通过矫直轮矫直；3、将药芯银钎料放置在夹具上，上压板开始压住药芯银钎料，并施加一定压力；4、夹具带动药芯银钎料开始旋转绕制成螺旋形盘状；5、将绕制好的药芯银钎料用切刀切断；6、夹具开始自动向下移动，同时，上压板也开始向下移动，将绕制好的螺旋形盘状钎料丝压平。本发明所述圆形药芯钎料饼制备方法操作简单，生产效率高，生产钎料质量好，材料利用率高，可节约原材料，大大提高了产品的成品率。

The invention discloses a round-shaped flux-cored brazing filler metal cake. The round-shaped flux-cored brazing filler metal cake is coiled into a plane spiral shape by a special-shaped flux-cored silver brazing filler metal disc, a preparing method comprises the following steps that 1, brazing filler metal is prepared into flux-cored silver brazing filler metal; 2, the flux-cored silver brazingfiller metal is straightened through a straightening wheel; 3, the flux-cored silver brazing filler metal is placed on a fixture, an upper pressing plate begins to press the flux-cored silver brazingfiller metal, and a certain pressure is applied; 4, the fixture drives the flux-cored silver brazing filler metal to begin to rotate to be wound into a spiral disc shape; 5, the wound flux-cored silver brazing filler metal is cut off by using a cutter; and 6, the fixture begins to automatically move downwards, meanwhile, the upper pressing plate also begins to move downwards, and wound spiral disc-shaped brazing filler metal wires are pressed to be flat. According to the preparing method of the round-shaped flux-cored brazing filler metal cake, operation is easy, the production efficiency is high, the produced brazing filler metal is good in quality, the material utilization ratio is high, raw materials can be saved, and the product yield is greatly improved.
