1. Dimensional inspection
(1) The first piece of the product manufactured by the angle saw and the cold-turning operator is used as a sample to verify the external dimensions. The length dimension is not allowed to be negative tolerance, the positive tolerance is +5mm, the width tolerance is ±2mm, and the diagonal deviation is not allowed. More than ±3mm. According to the test results, the size parameters of the edge saw and the diagonal saw are corrected in time.
(2) The angle saw and the cold-turn operator check the outer dimensions of the first plate of each turn to ensure that the dimensional tolerances are not exceeded, and at the same time check whether the appearance of each wool plate is stratified, foamed, polluted or soft. Especially when producing calender, check the surface of the board at any time. If there are any defects mentioned above, notify the press operator and technician to adjust the process parameters.
2. Mechanical property test
(1) Sampling method
a. For the specifications produced, the press operator should saw the test sample 10 minutes after the production is basically normal, carry out the routine test, and determine the test item of the second sample according to the test result. If the test result is ideal, every 6 afterwards Do routine testing for hours.
b. Laboratory personnel can sample and test at any time according to the production situation, and inform the press operator to provide relevant process parameters. The test results will serve as the main basis for internal assessment of product quality and technical skills.
(2) Testing procedures
a. The press operator saws the test sample and provides process parameters to the laboratory personnel.
b. After the laboratory personnel obtain the sample, first cut the density curve of the test piece and request that the density curve be fed back to the craftsman within 30 minutes.
c. Sawing the test pieces required for other performance indicators and testing them, and feedback the test results to the craftsman or squad leader within 2 hours.
