Scope
Main technical content: 4. Measuring characteristics 4.1 Rolling pressure error: 9kN ± 5% 4.2 Temperature display error: ±2℃ 4.3 Number of rolling cycles: 12 cycles/min ± 1 cycle/min 4.4 Dimensions of the test mold: length 300mm ± 2mm, width 300mm ± 2mm, thickness (50 ± 2)mm to (100 ± 2)mm 6. Calibration methods 6.1 General appearance characteristics: Check by visual inspection. 6.2 Rolling pressure display error: Place the standard force gauge on the platform of the roller forming machine, lower the rolling wheel, and adjust the total load to 9kN (line load 300N/cm). After the roller forming machine has stabilized, record the force gauge reading and measure it three times consecutively, taking the average value. 6.3 Temperature display error: Heat the standard thermometer and the temperature sensor of the roller forming machine to 100℃ simultaneously. Record the thermometer reading and the temperature display value of the roller forming machine, and calculate the temperature indication error. Measure three times and take the average value. 6.4 Number of rolling cycles: Start the roller forming machine and use a stopwatch to measure the number of rolling cycles of the rolling wheel in 1 minute. Measure three times consecutively and take the average value. 6.5 Dimensions of the test mold: Use calipers and depth gauges to measure the length, width, and height of the test mold at the ends and center three times each, and take the average value.
