摘要： A fastener (2) and method of attachment of such fastener to sheet material to provide attachment of a tubular fastener to the sheet material by extruding, without severing, portions of the sheet material completely through openings on the base portion of the fastener. In one embodiment of the invention, the extruded material is clinched on the top surface (8) of the base portion (6) by clinch members (12) integrally formed with the base portion. The fastener is internally threaded (16), lightweight and preferably heat-treated prior to attachment to the sheet material to provide fastener strength equivalent to or greater than that of much heavier nuts. Two types of such fasteners may be attached by a method which opens up a hole in the sheet material of a larger diameter than the major diameter of the threads (16) in the fasteners while simultaneously clinching the fastener in place. This eliminates the need to use thread-cutting bolts. The fasteners (2) may be connected together to form a strip to be fed into an automated assembly unit from a dispenser. In another embodiment of the invention, the extruded material is clinched on the top surface (8) by extruding it through clinch openings into the cavities of a die member that is brought into contact with the top surface of the fastener, each such cavity being aligned with and being somewhat larger than the clinch opening of the fastener that it is adjacent to.
摘要翻译： 一种紧固件（2）和将这种紧固件附接到片材材料的方法，以通过挤压而不断裂片材的部分而完全通过紧固件的基部上的开口而将管状紧固件附接到片材。 在本发明的一个实施例中，挤出的材料通过与基部一体形成的铆接构件（12）固定在基部（6）的顶表面（8）上。 紧固件是内螺纹（16），轻质并且优选在附接到片材之前进行热处理，以提供等于或大于较重的螺母的紧固件强度。 两种类型的这种紧固件可以通过一种方法来连接，该方法在紧固件中同时将紧固件固定在适当位置的同时在紧固件中打开直径大于螺纹（16）的主直径的片材中的孔。 这样就无需使用螺纹切削螺栓。 紧固件（2）可以连接在一起以形成从分配器供给到自动组装单元中的条带。 在本发明的另一个实施例中，挤出的材料通过将其穿过紧固开口挤压到与紧固件的顶表面接触的模具构件的空腔中而铆接在顶表面（8）上，每个这样的空腔对准 并且比其相邻的紧固件的紧固开口略大。
