ForceTec 无铆螺母座圈安装系统

      ForceTec is a unique method of installing an innovative and cost effective rivetless nut plate. Unlike conventional riveted or swaged-in nut plates, the ForceTec system radially expands a retainer into a hole. The retainer is designed to be permanent, and only the nut itself requires replacement. 

      ForceTec是一种创新和低成本的无铆钉螺母的独特安装方法。与传统的铆接或嵌入式螺母座圈不同,ForceTec系统将螺母座圈径向挤压,固定在孔中。螺母座圈是持续应用的,只有螺母本身需要更换。 

       ForceTec rivetless nut plate system is widely used as an alternative to traditional riveted nut plates. ForceTec’s simple installation makes it a cost effective option, significantly reducing labor and maintenance costs over the life of the aircraft. ForceTec eliminates the need for satellite holes and rivets, which are required for most nut plate installations. Instead, ForceTec is fastened to the structure by radially expanding the ForceTec nut plate barrel into the hole. The expansion creates high interference between the barrel and the structure that allows the nut plate to resist torque and pushout. ForceTec installations exceed the requirements of MIL-N-25027 for torque and pushout. In addition, cold expansion of the retainers into the hole imparts compressive residual stresses into the surrounding material, increasing the fatigue performance of the hole.

      ForceTec无铆螺母座圈系统被广泛用于替代传统铆接螺母托板。 ForceTec安装便捷的特点使其成为一种经济高效的选择,显着降低飞机使用寿命期间的人力和维护成本。 ForceTec消除了大多数托板螺母安装所需的卫星孔和铆钉。取而代之的ForceTec螺母座圈被经向挤压固定在孔中。螺母座圈与结构的挤压形成高干涉配合,这种高干涉配合可以有效地抵抗扭动和推出。 ForceTec的安装超出了MIL-N-25027军标标准对扭矩和推出的要求。另外,螺母座圈在孔中被冷挤压使周围的材料产生的残余压应力,增强了孔的疲劳性能。

安装程序、工具

The ForceTec Tooling System uses the same Puller Unit and PowerPak as our Split Sleeve Cold Expansion system, however, there are variations in the mandrels, sleeves, nose caps, and other durable tooling. A complete ForceTec system includes (but is not limited to):

ForceTec系统与冷挤压开缝内衬系统使用相同的拉枪和液压泵,然而,芯棒、衬套、鼻顶帽等其他耐用工具是不一样的。一个完整的ForceTec系统包括(但不限于): 

• Cutting Tools    刀具 

• Mandrel & Nosecap  芯棒和鼻顶帽 

• Split Sleeves (depending on installation method)   开缝衬套(取决于安装的方法) 

• Check Gages (combination & mandrel)  检查量规(组合量规&芯棒量规) 

• Puller & PowerPak  拉枪&液压泵 

Installation Procedure

安装步骤: 

ForceTec Rivetless Nutplates can be installed using a split sleeve, mandrel only, or AIM system. The best installation for your application depends on a variety of factors including installation access, material, and desired installation speed and modularity. A major OEM time study completed of ForceTec showed that in the time it took to install 100 riveted nut plates, they could install 665 ForceTec retainers with zero defective installations. ForceTec also allows the immediate assembly of other components without waiting for adhesives to cure.

ForceTec 无铆螺母座圈能够使用开缝衬套,芯棒或AIM系统进行安装。对于您的应用,最佳的安装方式取决于多种因素,包括安装环境,材料和要求的安装速度和模式。在一项ForceTec完成贴牌生产所需时间的调查中显示,在安装100个铆接螺母板的时间内,可以安装665ForceTec无铆螺母座圈,而且,零缺陷安装。无需等待粘合剂固化,ForceTec允许立即装配其他部件。 

Below is an example of a classic ForceTec open retainer being installed with a split sleeve.
