Visually inspect the quality of the product.
5.3 Machine performance
5.3.1 Test methods in 4.3.1 of this standard
Start the motor and move the punch up and down 30 times continuously, visually inspect the quality of the product. 5.3.2 Test method in Article 4.3.2 of this standard
5.3.2.1 Test conditions
Fill with lubricating oil and run at no load for 2 minutes;
The distance between the nailing machine and the surrounding objects is not less than 1m. The nailing machine is in the state of up and down movement of the punch; The sound pressure level of the background interference noise should be at least 10dB(A) lower than the sound pressure level of the machine noise; The microphone is 1.0m above the ground and parallel to the horizontal plane. The measurement point position is shown in Figure 1. 39
Machine (looking down)
5.3.2.2 Test instrument
A sound level meter with an accuracy of ±0.7dB(A).
5.3.2.3 Test value
QB/T1481—1992
The noise value measured at the four measurement points shall be the maximum value. 5.3.3 Test method in clause 4.3.3 of this standard
Measuring points (4 places)
When the punch is at the lower limit point, push one side of the slider by hand and measure the gap on the other side with a feeler gauge. Then, push the slider in the opposite direction and measure the gap on the other side. Take the larger value of the two measured values. 5.3.4 Test method in clause 4.3.4 of this standard
Use a special coaxiality measuring mandrel to measure. First, move the punch up to the upper limit point, then insert the upper end of the mandrel into the upper die positioning hole, then turn the pulley to move the mandrel down and slowly insert it into the lower die positioning hole.
