Setting Force Adjustment; Adjustment For Standard Pop Nuts - Stanley POP PNT1000L-PC Bedienungsanleitung

Setting Force Adjustment

• Verify the proper Valve Spring is selected – See "Setting Force Valve Spring Selection"
• Adjust the setting force of the tool according to insert size and thickness of work piece as indicated in the instructions
below.
• Test 5 pieces before beginning production work to ensure proper setting of the POP NUT™.
• Proper setting force is critical:
• Low setting Force results in insuffi cient stroke and clamping of the insert, leading to a Spin Out failure in the
application
• High setting force results in excess stroke and possible insert threads stripping and Mandrel damage

Adjustment for Standard POP NUTs™

Use the following procedure to determine the proper setting requirments for the SPH, SFH, APH, AFH, SPS, SFS, APS, AFS
& SRH Series of POP NUTs™:
1. Determine minimum stroke, "S
2. Set the insert in a test piece with the proper thickness
3. Measure the value of S
Table 8: Stroke Formula for Standard POP NUTs™
Thread Size Stroke (S
M6X1.0 2.4+(N-t)-0.4
M8X1.25 RLT 2.4+(N-t)-0.4
M8X1.25 2.8+(N-t)-0.4
M10X1.5 3.0+(N-t)-0.4
M12X1.75 3.2+(N-t)-0.4
Example: SPH625 POP NUT™ with a 1.5mm thick work piece
t = Workpiece thickness, N = 1 value of last 2 digits of POP Nut number
t = 1.5mm, N = 1 (25)= 2.5
Min
S = 2.4 + (N – t)–0.4
Min
S = 2.4 + (2.5 – 1.5)–0.4

Check POP Nut threads for damage or sticking to Mandrel for 5 test pieces
• If okay, setup of tool is complete
• If damaged, Decrease setting load - See "Adjustment of Setting Force"
