S2 places dynamometer 20 in the location of workpiece, is fed vertically downward by the ram 1 of the lathe, make the rolling
Wheel 9 is contacted with the dynamometer 20, and keeps certain contact action power；
S3 reads the contact action power numerical value FNWith pressure value P measured by the pressure gaugeN, and calculate calibration system
Number KN:
S4 repeats step S3, repeatedly measures the calibration coefficient K under the conditions of the different contact action powerN, and count
It calculates and obtains average calibration coefficient K0:
S5 calculates the practical contact action power F of rolling operation:
F=p*K0；
Wherein, the actually measured real-time pressure value of p- measuring cell 7.
The spoke noise reducing plate pressure calibration method of the utility model introduces average calibration coefficient K0It is obtained by repeatedly measuring
The average value for taking calibration coefficient can effectively reduce the measurement of contact action power by this method and calculate error.

Novel further includes controller, wherein measuring cell 7 is preferably pressure transmitter, and the pressure transmitter is for measuring transmission medium
Pressure, and generate real-time pressure signal, controller is configured to obtain the real-time pressure from the pressure transmitter
Signal, and real-time contact directed force F, i.e. F=p*K are calculated according to real-time pressure p0；Then, the controller is by the reality
When contact action power compared with preset first threshold and second threshold, and the first threshold be less than the second threshold；
When the real-time contact active force is less than the first threshold, the controller controls the lathe and feeds to Z axis forward direction, increases
Add the real-time contact active force；When the real-time contact active force is greater than the second threshold, the controller controls institute
Lathe is stated to Z axis feed reversing, reduces the real-time contact active force, the utility model can control real-time contact active force
Within preset range, the crimp quality of spoke noise reducing plate is effectively controlled.
A kind of working principle of the spoke noise reducing plate Special pressing head of embodiment of the utility model is: the spoke of the utility model
Noise reducing plate Special pressing head is the special equipment designed for crimping motor-car and 18 spoke noise reducing plate of high-speed rail wheel, is mountable to
On the lathe of two-axle interlocking, the two-axle interlocking is horizontal feed X-axis and vertical feed Z axis, which for example can be numerical control
Vertical lathe.
When carrying out rolling operation, as shown in figure 8, first by 18 clamping of wheel on rotary table 19, cleaning wheel 18
The noise reducing plate mounting surface of spoke, then, the first brushing binder on the noise reducing plate mounting surface of 18 spoke of wheel, then noise reducing plate is put
It sets on 18 spoke of wheel.It is cut from spoke middle position, 1 vertical feed of ram to measuring cell 7 shows preset value, court
The rolling of 18 internal direction of wheel, the internal direction are that X-axis is positive in Fig. 8, are returned under spoke middle position continues after the completion
Knife completes entire press fitting process towards the rolling of 18 outside direction of wheel, which is along X-axis negative sense.
When cutting, contact rolling wheel 9 with noise reducing plate by 1 vertical feed Z axis of ram, continuing feeding compresses disc spring 12
Pressing force is generated, while by 11 power transmission of core to transmission medium, so that the glycerol 14 in accommodating cavity 2.1 is generated pressure, pass through behaviour
The measuring cell 7 made on panel reads pressure, and the pressure value of reading is substituted into above-mentioned F=p*K0In you can get it contact action
