Spring factory is usually carried out in the hardware.com/spring' target='_blank'>stainless steel spring announced before the inspection, the bomb first yellow narrowed to the test load for many times, when the experimental load pressure and heavy load at the time, can carry out pressure and load as the experimental load, but the pressure and flow pressure and load of 1 can not exceed the mindset. 6 times. 2. For load test are prepared ahead of time: before the match with dividing the value of the third class standard about dynamometer or draw a precision standard weight to load test instrument for proofread and correct, ensure the tester hardware machinery is higher than 1%; Use block gauge with proofread and correct the length of the load tester read value deviation. Stainless steel spring pressure with certain height to width ratio of load test: will work with a specific aspect ratio the same gage block placed pressure plate load test apparatus of the central government, on the gauge block is loaded with the sample figure the principal values of load, then the clamping precision positioning screw or slightly, accurate positioning of the gage block in the measured yellow, mediation back to zero, remove shells yellow weight, will play the yellow pressure to certain height to width ratio, and write out the relative load, finally according to the calibration load tester deviation, the myopic degree to carry out the corresponding changes. To eliminate the pressure plate on inhibition play Huang Gang parts, load tester omen F0 value material 0. 05F; Account of load tests on the number of early reading to F0 value and its length, then load again, make accident warning value change over divided the shape of a variable.
