摘要： The invention relates to blind rivets and to methods of joining therewith. The method of the invention is suitable for joining two or more workpieces with a blind rivet. The method includes the first step of positioning a blind rivet at a point of overlap of two or more workpieces, the blind rivet including a rivet body and a mandrel. The next step involves rotating the mandrel about a longitudinal axis thereof and contacting the mandrel with the overlapping workpieces, wherein the mandrel is rotated at a speed to cause plasticization of the overlapping workpieces. The method then involves causing the mandrel to penetrate through the plasticized overlapping workpieces and form an aperture therethrough. A further step of the method involves capturing a portion of the overlapping workpieces that is displaced upon the penetration of the mandrel and securing the rivet body within the aperture to join the overlapping workpieces. The invention also includes a workpiece penetrating and joining blind rivet. The blind rivet includes a rivet body including a shank having a first end, a second end and an axial passage extending through the shank between the first and second ends. Also included is a mandrel including a shaft positioned within the axial passage and a head at one end of the shaft for contacting a workpiece wherein the mandrel is configured so that when contacting the workpiece, being rotated about a longitudinal axis thereof at a speed to cause plasticization of the workpiece and being caused to penetrate through the plasticized workpiece the mandrel cores a portion of the plasticised workpiece, displaces the portion from the workpiece and forms an aperture in the workpiece.

摘要翻译： 本发明涉及盲铆钉及其连接方法。 本发明的方法适用于将两个或更多个工件与盲铆钉接合。 该方法包括将盲铆钉定位在两个或多个工件的重叠点处的第一步骤，盲铆钉包括铆钉体和心轴。 接下来的步骤涉及使心轴围绕其纵向轴线旋转并使心轴与重叠的工件接触，其中心轴以一定的速度旋转以引起重叠的工件的塑化。 该方法然后包括使心轴穿过塑化的重叠工件并形成穿过其中的孔。 该方法的另一步骤包括捕获重叠工件的一部分，该部分重叠工件在芯棒穿透时移动，并将铆钉体固定在孔内以连接重叠的工件。 本发明还包括工件穿透和连接盲铆钉。 盲铆钉包括铆钉体，其包括具有第一端，第二端和在第一和第二端之间延伸穿过柄的轴向通道的柄。 还包括一个心轴，其包括定位在轴向通道内的轴和在轴的一端处的头部，用于接触工件，其中心轴构造成使得当接触工件时，以其速度绕其纵向轴线旋转， 工件的塑化并被穿透塑化的工件，心轴将可塑化工件的一部分芯部移出工件的部分并在工件中形成孔。
