摘　　要：主要设计了一种新型钎料的成型模具———三叶内摆线形滚动拉丝模,对其结构特征给以描述,通过算例将新型钎料与棒状钎料进行对比,详细介绍新型三叶内摆线形钎料的实现过程。结果表明,与棒状钎料相比,新型三叶内摆线形钎料与三钢球的接触面积大,增加幅度为15%～50%。在拉拔长度一定的条件下,与等横截面积的棒状钎料相比,三叶内摆线形钎料的横截面周长及体表面积较大。设计的新型钎料成型模具可有效减少能耗,提高拉拔效率,实现三叶内摆线形新型钎料的产业化。A wire drawing dies of new brazing filler metal was designed. The structure feature of this wire drawing dies was described, and the body surface area of the new brazing filler metal was compared with rod-like brazing filler metal through examples,the process of trefoil hypocycloid brazing filler metal was introduced in detail. The results indicate that the contact area of trefoil hypocycloid brazing filler metal and three steel ball is larger about 15%-50% than the rod-like brazing filler metal. As compared to general trod-like brazing filler metal,the cross-sectional perimeter and body surface area of trefoil hypocycloid brazing filler metal is also larger under the same drawing length. The novel wire drawing dies can effectively reduce energy consumption and improve the drawing efficiency. Industrialization of trefoil hypocycloid new brazing filler metal would be realized in future.
