Related standards and product drawings.
4 Inspection of general items
The following inspection purposes and inspection instruments shall be in accordance with the relevant provisions of 10231.1-2001: a) Marking, packaging:
b) Appearance, surface roughness:
c) Material, hardness, surface treatment.
5 Inspection of the outer diameter and thickness of round die
5.1 Inspection instrument
The value of the outer diameter micrometer is 0.01mm. 5.2 Inspection method
Use an outside diameter micrometer to measure one point at any position on the outer and outer surfaces of the plate, and then measure another point. The values ​​shall all conform to the provisions of the standard.
JB/T10231.8—2002
6 Inspection of the opposite side dimensions of hexagonal die
6.1 Inspection measuring tool
Outer diameter micrometer with a graduation value of 0.0mm
6.2 Inspection method
Use an outside diameter micrometer to measure the middle part of the three positions of the hexagon respectively. The measured values ​​shall conform to the provisions of the standard. 7 Radial runout of the outer circle of the circular die to the axis of the explosion 7.1 Testing equipment
Indicator with a graduation value of 0.0m, pin-shaped threaded mandrel, motion tester, magnetic table stand: 7.2 Testing method
Put the drawing die on the corresponding threaded mandrel (the mandrel with the tightest fit), so that the indicator probe directly touches the outer circle of the die (any part can be), the center of rotation, the plate does not rotate one circle, the maximum change in the indicated value of the indicator is the radial runout, see Figure 1. Figure 1 Testing radial runout and end face runout indicator diagram of the end face runout of the die facing the thread drawing B.1 Testing equipment
Connected. 1.
B.2 Inspection method
Put the die on the male thread core (with the most suitable mandrel), make the indicator probe vertically contact the outer surface of the thread, rotate the mandrel to make the die rotate a circle, the maximum change in the indicator value is the end face circular runout, see Figure 1, 9. The circular runout of the die cutting edge to the outer circle 9.1 Inspection equipment
A lever indicator with a graduation value of 0.01um, a magnetic table stand, a V-shaped iron and a positioning baffle or a special inspection fixture. 9.2 Inspection location
Inspect at the outer edge of the cutting cone.
9.3 Inspection method
Place the round die in a V-shaped iron and lean against the fixed baffle, the indicator probe vertically contacts the outer edge of the cutting edge, rotate the die for one circle, the maximum change of the indicator value is the maximum possible change, see Figure 210. The oblique diagram of the hexagonal die cutting edge to the screw shaft is shown in Figure 210. 10.1 Inspection equipment
Red indicator with a stiffness value of 0.01m, chain screw core shaft, dynamic inspection, magnetic table stand. 2

According to 9.2.
10.3 Inspection method
Figure 2 Schematic diagram of the oblique circular runout of the cutting edge of the circular die for inspection JR/T10231.B—20Q2
Screw the six-die plate into the end of the most suitable (poor matching) mandrel of the corresponding conical screw effect mandrel, so that the end face of the mandrel is close to the starting point of the extreme tooth control part, but not allowed to enter the cutting part, and the right side is supported with a semicircular tip. The indicating probe touches the outer edge of the cutting blade vertically, and the mandrel is rotated to make the die rotate one circle. The maximum change in the indication of the indicator is the oblique circular runout ...
