The molds used in the precision stamping process are equipped with guide pins to correct the length of the material each time it is fed into the mold to ensure the accuracy of stamping production. In order to truly realize this correction, the feeder must be equipped with a relaxing device. With the realization, after the leading edge of the die guide pin enters the stamping material, the material of the feeder is just in a relaxed state. At this time, the guide pin can correct the error in time, and this relaxation time is the angle of the feeder.

Only in actual use, many operators are using the feeder for the first time. After replacing the new die for the press, they often only remember to adjust the height of the feeder (because the die height is different after the die change, the feed height needs to change This is very intuitive), but ignores the adjustment of the feeder's relaxation angle. At this time, the phenomenon of inaccurate feeding will occur. The operator is often unfamiliar with the feeder and often cannot think of the problem. At this time, the operator will complain about feeding. The machine is not good, can only be applied to a mold, in fact, this is because the feeding machine is not correctly adjusted due to the feeding angle is not correct. At this time, many stamping owners may have doubts. The feeder feeding angle is generally within the range of 270-350 degrees. Why should the angle of relaxation be so accurate? As a professional feeder manufacturer, JinZide Machinery provides answers for our customers here:

In fact, the reason for this problem is very simple, that is, the stamping process of each mold is different, so the mold thickness, guide pin length is not the same, the change in the positive guide pin length will make the guide pin insert material time is different, this If the time is changed, if the angle of relaxation is still according to the previous time, the clamping material is not correctly realized, so that the guiding function of the guiding pin cannot be truly realized, resulting in inaccurate feeding length. Therefore, after the mold is changed, the feed angle adjustment of the feeder is an indispensable step. The standard of adjustment is to relax after the mold guide pin enters the hole position of the material. When the mold rises, the guide pin feeds the material before the pin hole of the material is ejected. Clamping material is the basic guideline, so as to truly ensure the punch press production with high precision.
