Punch feeder step test method

     The accuracy of the feeder's feeding steps is one of its significant advantages over manual feeding. After the feeder is installed on the press, it is usually necessary to test its feeding step to check whether its performance is stable or not, and there are three kinds of test methods, which are explained in detail here.
      It should be noted during the test: the actual feeder of the punch press is not allowed to feed the material in steps, which may be the reason of the feeder, or the reason of the mould, or other external reasons, so it is necessary to use the step test without installing the mould and the step test after installing the mould in two ways to make a comprehensive judgment.

    Punch Press Feeder

     1, without the installation of the mould, a single stamping processing test, it is not suitable for high-speed roller feeder feeding. Test method: adjust the feeding step, single operation of the punch press, feeding a mark out of the position after feeding, single operation feeding ten times, cut the material belt, the 10 times the mark feeding values for testing, to see whether the punch feeder step is accurate.

    Note: Because the high-speed roller feeder is driven by the output shaft of the punch press, the output shaft basically has a certain gap, in the single feeding will be due to the output shaft has a gap also feed unstable, so high-speed roller feeder is not suitable for the use of a single feeding marking test, and need to be used many times to feed the comprehensive test.

    2、Not install the mould, many times stamping processing test, which is suitable for punch press feeder equipment. Test method: adjust the feeding step, make a mark on the material before the initial feeding, then make a second mark after using continuous stamping for ten times, and then return the material to the mark before the first feeding, and then reuse continuous feeding for ten times to re-mark for the 3rd time.
Punch Feeder Continuous Step Test
Check the gap value between the 3rd mark and the 2nd mark, if the two gap values are within the accuracy range of the feeder then the feeding is accurate; if the two gap values are greater than the accuracy range of the feeder then the feeding is not allowed.

      3、After installing the mould, check whether the product meets the requirement of accuracy after feeding several times.

Usually use 1 and 3 or 2 and 3 two kinds of combination to feed step determination, if 1, 2 accurate, 3 inaccurate, it shows that the problem is in the mould; if 1, 2, 3 are inaccurate, then the problem lies in the punch press feeder, need to check its air source, feeding relaxation angle.
