1、選擇拉釘（抽芯鉚釘）的因素 This illustration provides a graphic representation of the POP blind rivet selection factors described below.此圖提供了以下描述的KSEET拉釘（抽芯鉚釘）的選擇因素的圖形表示。 （拉釘）抽芯Rivet Terminology/Nomenclature鉚釘術(shù)語1. Hole Size 1，拉釘（抽芯鉚釘）開孔尺寸 拉釘Hole size can be important in blind riveting.孔的大小在鉚接中非常重要。 Too small a h

2、ole will, of course, make rivet insertion difficult.過小的孔，當然會，使抽芯鉚釘插入困難。 Too large a hole will reduce the shear and tensile strengths.過大的孔會降低剪切和拉伸強度。 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.它也可能導(dǎo)致產(chǎn)品鉚接不牢，或者產(chǎn)品

3、直接脫落，而達不到拉鉚效果(Best practice is to follow the hole size recommendations provided. （最佳做法是按照產(chǎn)品目錄所提供的孔大小的建議）。 Avoid burrs in and around the holes.避免毛刺和周圍的孔過大。 2. Grip Range 2，拉釘（抽芯鉚釘）鉚接范圍 The recommended thickness range over which the body length will consistently provide a proper setting in a hole of t

4、he specified diameter.推薦的厚度范圍該抽芯鉚釘身長度將在指定直徑的孔適當?shù)拈L度設(shè)置。 3. Shear 3。拉釘（抽芯鉚釘）抗剪力 The load applied to a fastener along the joint interface.負載施加到沿接合界面的緊固件。 4. Tensile 4，拉伸力The load applied to a fastener along its length.負載施加到沿其長度的緊固件。 5. Joint strength 5，接頭強度 First determine the single-joint tensile and s

5、hear values required for the application.首先確定所需的應(yīng)用程序的單個關(guān)節(jié)的拉伸力和剪切力值。 These are functions of total joint strength, fastener spacing, rivet body material, and rivet diameter.這些都是關(guān)健的力量，緊固件間距，鉚體材料和鉚釘直徑的功能。 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.然后參考“剪切”和“拉力”的鉚釘選型指南在產(chǎn)品上的，然后選擇一個合適的抽芯鉚釘，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。聯(lián)合厚度 Measure the total thickness of the materials to be

7、joined.測量的材料的總厚度被接合。 This determines the required "grip" of the rivet you select.這將決定您選擇的抽芯鉚釘所需的“抓地力”。 You must select a rivet with a grip range that includes the work thickness required.你必須選擇一握范圍，包括所需的工作厚度抽芯鉚釘。 7. Nature of material7。抽芯鉚釘（拉釘）選擇材質(zhì)Both the rivet and the materials to be fast

8、ened will affect the ultimate joint strength.兩個拉釘（抽芯鉚釘）和材料要被緊固鉚合將會影響最終的接合強度。 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.作為一項規(guī)則，抽芯鉚釘材料應(yīng)具有和鉚接產(chǎn)品相同的物理和機械性能的要被緊固的材料，因為有不同材質(zhì)的拉釘，差異性可能會導(dǎo)致由于無論是材料疲勞或電化腐蝕的結(jié)合失敗。 8. Head Style 8，拉釘（抽芯鉚釘）頭型 圓頭抽芯鉚釘The low-profile domed head is appropriate for most applications.圓頭圓 適用于大多數(shù)應(yīng)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，當軟或脆的材料被固定在一個剛性的材料時，該大帽抽芯鉚釘應(yīng)該考慮，因為它提供支承表面是普通的兩倍。 若產(chǎn)品Where a flush surface is required, the countersunk head style should be selec
