Punch production to ensure the quality of stamping products precision, and the impact of stamping products precision for many reasons, such as punch die, punch, and punch automatic feed the stability of the whole production line equipment.Today we will talk about several factors that affect the precision of stamping parts by automatic feeder:
One. If the stamping parts are inaccurate due to feeding quantity error or feeding direction deviation of the automatic feeding machine, first check if there is metal or other foreign matter in the feeding roller or gear, and if there is interference in the starting and releasing of the feeding and the action sequence of the punch press.When the material is fed into the feeder, the roller will slip.To understand the cause of the failure, you just need to make adjustments for different problems.
Two. Automatic punch feeder transmits too fast and the amount of feed is too much. In this case, the equipment should be customized in time to check whether there is noise interference with the micro-switch and wire terminal of the automatic feeder.If there is noise interference, replace the wire between the microswitch and the terminal.And the use of metal mesh isolation line.
Three, relax frequently, automatic feeder roller is not smooth, the main reason is that the automatic feeder relax CAM micro switch SW direction of signal is not normal and feed migration phenomenon, air compressor parts doesn't work properly at the same time, this time only need to adjust air compressor parts properly or replace solenoid valve, cylinder, piping, etc., and check whether the wire fall off or replace micro switch or replace the relay electrical box.
Four, the automatic feeder has fixed direction is not correct, it may be the feeding roller pressure is not enough, or there is a foreign body in the rough edge of the mold, according to different circumstances should be timely checked and solved, increase the pressure, the width of the coil and the mold guide plate is appropriate?Or the touch and NC feeder are in a straight line, check the baffle and stripper.
Five, automatic feeder production time are not allowed to be suddenly occasionally happen, this kind of circumstance is NC feeder adjustment quantity of the material error of leveling machine and servo feeder whether match or leveling machine and NC feeder of middle distance and material arc height and punch turnover number whether appropriate, then there is between the roller and servo motor drive gap is larger.At this time will only need to tighten the belt pulley.
The above five situations are the five common situations that affect the accuracy of automatic feeder. Of course, there are also other reasons, which can only be solved according to the actual production of automatic feeder and the feedback information.
