目前在国际市场见到的整体钎子,只有一字、三刃、十字形三种,最多的为一字、三刃形,以瑞典为代表。法国七十年代样本中,曾出现过一种直径较大的八齿(锥形齿)球体形整体钎子,因其主要与压配合固齿工艺和小直径钎头不相适应,未能投入生产而自灭了。此外锥形齿的坚固性不足,边齿倾角过大,布齿不均(中齿过稀),排粉系统和几何结构参数不够合理,抵抗径向磨损能力较弱等,都是使其不能与片状合金整体钎子竞争的重要因素。因此目前世界上球齿形整体钎子,仍然是一个空白。
Currently in the international market to see the overall solder, only one word, three-edged, three cross-shaped, up to the word, three-bladed, represented by Sweden. In the French sample of the 1970s, a large-diameter eight-tooth (conical tooth) ball-shaped monolithic brazing element appeared. It failed to be put into practice due to its incompatibility with press-fit solid-tooth technology and small diameter drill bits Production and self-destruction. In addition, the lack of firmness of the conical teeth, excessive inclination angle, uneven cloth teeth (too thin teeth), powder discharge system and geometric parameters are not reasonable enough to resist the weak radial wear, etc., are to make it impossible An important factor in the competition with sheet metal monolithic brazing rods. Therefore, the overall global shape of the ball-shaped solder, is still a blank.
