TOOLING AND GAGING VERIFICATION REQUIREMENTS 3.1 Tooling and Gaging Verification
10、Prior to the listing of new gaging and tooling numbers in this procedure, the fitting/tooling system supplier shall demonstrate the interchangeability/capability by assembling and gaging two sample fittings of each size of each manufacturer listed in the PRI-QPL 5958. The assembled fittings shall be
11、 tested to and pass the AS5958 impulse test requirements. Potential suppliers shall submit a plan to demonstrate interchangeability/capability to the Performance Review Institute (PRI), G-3 Fluid Distribution, Qualified Products Group (QPG), at PRI, 161 Thorn Hill Rd, Warrendale, PA 15086-7527. The
12、QPG will grant approval for the suppliers numbers and name be added for the applicable tools or gages after demonstrating interchangeability/capability. 4. GENERAL 4.1 Dimensions All dimensions in this specification are in inches. 4.2 Tube End Preparation The tube ends shall be cut square as defined
13、 in Figure 1. The tube ends, I.D. and O.D., shall be free of burrs. 4.3 Tube Condition - Sealing Area The tube sealing area shall be in accordance with the tubing specification finish requirement. There shall be no scratches or other handling damage marks. This area shall be clean and free of paint,
14、 glue or any other foreign substance. 4.4 Tube Marking 4.4.1 Pre-Applied Tube End Marking At least one pair of marks, (positioning marks and inspection marks) as shown in Figure 1, shall be pre-applied with the given dimensions from Table 1 to each prepared tube end prior to fitting installation. A
15、suitable permanent method such as ink stamp, anodize, or electro-etch, etc., may be used. Should the tube ends be unmarked, the appropriate marks shall be applied using tube marking gage as shown in Figures 2A and 2B, and using a suitable permanent ink felt tipped pen such as Sanford Sharpie TEC (Tr
16、ace Element Certified) marker no. 13401. NOTE 1: Due to the possibility of contaminating titanium tubing, inks which contain lead, 25 ppm maximum, or free halogens, 225 ppm combined maximum, should not be used for marking.

23、ND ASSEMBLY 5.1 Fitting Installation 5.1.1 Positioning Mark Locate the edge of the unswaged fitting “ring” over the positioning mark as shown in Figures 3A and 3B. The length of the positioning mark is the amount of positioning tolerance allowed. The edge of the fitting “ring” may be anywhere along
24、the length of the positioning mark. FIGURE 3A - POSITIONING MARK AT MINIMUM TUBE INSERTION FIGURE 3B - POSITIONING MARK AT MAXIMUM TUBE INSERTION FIGURE 3 SAE INTERNATIONAL AS5959B Page 5 of 11 5.1.2 End Fittings In general, end fittings have a tube stop and do not have as much positioning allowance
25、 (see Figure 4). Even with this condition, the tube end shall be marked for inspection purposes to verify that the tube was inserted to at least the minimum insertion depth. FIGURE 4 - END FITTINGS TUBE POSITIONING(NOTE: TUBE IS BOTTOMED INTO THE FITTING) 5.1.3 Shared Insertion In the case of unions
26、, the tube insertion allowance is shared by each leg of the union. If one tube end is inserted to maximum depth, then the opposite tube end can only be inserted to a minimum depth as shown in Figure 5. This shared insertion condition is only applicable to unions, which have a through bore to allow p
27、lacement onto cut lines during repair. NOTE: Under maximum insertion conditions, it will not be possible to see the Inspection mark until after swaging. FIGURE 5 - EXAMPLES OF ACCEPTABLE SHARED TUBE INSERTION CONDITIONS FOR UNIONS BEFORE SWAGING SAE INTERNATIONAL AS5959B Page 6 of 11 5.2 Fitting Ass

32、ng interchangeability in accordance with 3.1 of this standard. SAE INTERNATIONAL AS5959B Page 7 of 11 5.3 Fitting Installation With the fitting positioned onto the tube as described in 5.1, select the proper tool for the application. The ring “forward/push“ motion tool is the preferred tool for most
33、 applications, however, a ring “reverse/pull“ motion is required for some applications where there is a lack of tooling space. For the forward/push motion, align the swage tool to one leg of the fitting so that the “ring“ is nested into the movable jaw of the tool and the front opening of the tool i
34、s bottomed into the “fitting body“ as shown in Figure 7B. For the reverse/pull motion, align the swage tool to one leg of the fitting so that the “fitting body“ is bottomed in the movable jaw and the “ring“ is nested into the tooling body as shown in Figure 7A. However, not all shared fittings can b
35、e swaged in the reverse/pull position. See Figure 7C for an example. 5.3.1 Tool Pressurization The hydraulic pressure sources are available from the suppliers listed in Table 4. Apply hydraulic pressure (10 000 psi ) to the tool to advance the fitting ring or fitting body to complete the assembly pr
36、ocess as shown in Figure 8. The swage is complete when the ring has advanced enough to meet the inspection gage length as listed in Table 5. WARNING: Assembly tools operate under high-pressure hydraulic loads. The tools have moveable jaw and extreme loads can be applied to close the jaw relative to
37、the tool body. Operate with care to avoid “pinch points” that could result in injury to the hand or fingers. CAUTION: Fitting must always be fully nested into tool to maximize tool life. Failure to seat the fitting into the bottom of the tool jaw will cause excessive loading of the tool flanges and
38、could result in damaging the fitting and/or premature failure of the tooling jaw.

40、iers may be added after demonstrating interchangeability in accordance with 3.1 of this standard. 5.3.2 Re-Engagement of Tooling (if necessary) If it is determined that the ring has not been fully advanced in the initial swage process, the fitting can be reinserted into the tool jaw and the swage pr
41、ocess can be repeated. The fitting should be fully nested into the tool jaw, and if possible, it is recommended that the tool be rotated to the opposite side of the initial tool placement. This will help to distribute the tool pressure about the contact surfaces on the fitting. Input the pump pressu
42、re at 10 000 psi, to fully advance the ring.

ASSEMBLED FITTING INSPECTION 6.1 Ring Advancement Inspection After fitting installation, ring advancement must be verified using the inspection gage at least at three different locations onthe swaged fittings, when usin

If an inspection gage is not available, dimension Z, as shown in Figures 8A and 8C and Table 5 must be verified at lea
45、st at three different locations on the swaged fittings.
