选择抽芯铆钉的要素

1、选择拉钉（抽芯铆钉）的因素 This illustration provides a graphic representation of the POP blind rivet selection factors described below.此图提供了以下描述的KSEET拉钉（抽芯铆钉）的选择因素的图形表示。 （拉钉）抽芯Rivet Terminology/Nomenclature铆钉术语1. Hole Size 1，拉钉（抽芯铆钉）开孔尺寸 拉钉Hole size can be important in blind riveting.孔的大小在铆接中非常重要。 Too small a h

2、ole will, of course, make rivet insertion difficult.过小的孔，当然会，使抽芯铆钉插入困难。 Too large a hole will reduce the shear and tensile strengths.过大的孔会降低剪切和拉伸强度。 It may also cause bulging or separation of the members by allowing the rivet to expand between them instead of only on the blind side.它也可能导致产品铆接不牢，或者产品

3、直接脱落，而达不到拉铆效果(Best practice is to follow the hole size recommendations provided. （最佳做法是按照产品目录所提供的孔大小的建议）。 Avoid burrs in and around the holes.避免毛刺和周围的孔过大。 2. Grip Range 2，拉钉（抽芯铆钉）铆接范围 The recommended thickness range over which the body length will consistently provide a proper setting in a hole of t

4、he specified diameter.推荐的厚度范围该抽芯铆钉身长度将在指定直径的孔适当的长度设置。 3. Shear 3。拉钉（抽芯铆钉）抗剪力 The load applied to a fastener along the joint interface.负载施加到沿接合界面的紧固件。 4. Tensile 4，拉伸力The load applied to a fastener along its length.负载施加到沿其长度的紧固件。 5. Joint strength 5，接头强度 First determine the single-joint tensile and s

5、hear values required for the application.首先确定所需的应用程序的单个关节的拉伸力和剪切力值。 These are functions of total joint strength, fastener spacing, rivet body material, and rivet diameter.这些都是关健的力量，紧固件间距，铆体材料和铆钉直径的功能。 Then refer to the "Shear" and "Tensile" in the Rivet Selection Guide on the pro

6、duct, and select a POP brand rivet that provides the values required.然后参考“剪切”和“拉力”的铆钉选型指南在产品上的，然后选择一个合适的抽芯铆钉，提供所需的值。 POP brand rivets are not certified for structural aerospace applications and such use is not recommended. 6. Joint thickness 6。联合厚度 Measure the total thickness of the materials to be

7、joined.测量的材料的总厚度被接合。 This determines the required "grip" of the rivet you select.这将决定您选择的抽芯铆钉所需的“抓地力”。 You must select a rivet with a grip range that includes the work thickness required.你必须选择一握范围，包括所需的工作厚度抽芯铆钉。 7. Nature of material7。抽芯铆钉（拉钉）选择材质Both the rivet and the materials to be fast

8、ened will affect the ultimate joint strength.两个拉钉（抽芯铆钉）和材料要被紧固铆合将会影响最终的接合强度。 As a rule, the rivet materials should have the same physical and mechanical properties as the materials to be fastened, because a marked dissimilarity may cause joint failure due either to material fatigue or galvanic corro

9、sion.作为一项规则，抽芯铆钉材料应具有和铆接产品相同的物理和机械性能的要被紧固的材料，因为有不同材质的拉钉，差异性可能会导致由于无论是材料疲劳或电化腐蚀的结合失败。 8. Head Style 8，拉钉（抽芯铆钉）头型 圆头抽芯铆钉The low-profile domed head is appropriate for most applications.圆头圆 适用于大多数应用。 However, when soft or brittle materials are fastened to a rigid backing member, the large flange head should be considered because it offers twice the bearing surface.然而，当软或脆的材料被固定在一个刚性的材料时，该大帽抽芯铆钉应该考虑，因为它提供支承表面是普通的两倍。 若产品Where a flush surface is required, the countersunk head style should be selec
