The molds used in the field of precision stamping are equipped with guide pins to correct the length of each material fed into the mold to ensure the precision of the stamping process. For this correction, the press feeder must be equipped with relaxation. The device is matched and realized. After the tip of the mold guide pin enters the stamping material, the punch feeder is just in a relaxed state, and the guide pin can correct the error in time, and the relaxation time is the relaxation angle of the punch feeder.
However, in actual use, many operators use the punch feeder for the first time. After replacing the new mold for the punch, it is often only necessary to adjust the height of the punch feeder (because the mold height is different after changing the mold, the feed height is high. It is very intuitive to change, but it ignores the adjustment of the relaxation angle of the punch feeder. At this time, the phenomenon of inaccurate feeding will occur. The operator is not familiar with the punch feeder and often cannot think of the problem. At this time, the operator Will complain that the punch feeder is not good, can only be applied to a mold, in fact, this is because the feeding angle of the punch feeder is not properly adjusted to bring the feed is not accurate. At this time, many stamping owners may have doubts. The feeding angle of the punch feeder is generally within the range of 270-350 degrees. Why is the angle of relaxation so precise? The following professional punch feeder manufacturers are here to answer your questions:
In fact, the reason for this problem is very simple, that is, the stamping process of each set of molds is different, so the thickness of the mold and the length of the guide pin are different. The change of the length of the guide pin will make the time for inserting the guide pin into the material differently. The time has changed. If the time of relaxing the angle is still not properly realized by the previous one, the guiding function of the guiding pin can not be realized, which ultimately leads to the inaccuracy of the feeding length. Therefore, the adjustment of the feeding angle of the punch feeder after replacing the mold is an indispensable part. The adjustment standard is to relax the mold lead pin after entering the material hole position. When the mold rises, the guide needle punches before the needle hole of the material is not released. Feeder clamping material is the basic principle, so as to truly ensure the high precision of punch press production.
