Feeders are used in heavy industry and light industry as a machine for conveying materials. Feeder has a high degree of accuracy, and is environmentally friendly, time-saving, and labor-reducing. Such a precision hardware brings efficiency to the enterprise. Then, when using a feeder, there is a problem of inaccurate feeding, and the root cause of this problem is. what is it then? Let me analyze the reasons for this problem and why:

Only in actual use, many operators are using the press feeder for the first time. After replacing a new one for the press, they often only remember that the press adjusts the height of the feeder (because the mold height is different after the mold is changed, the feed height Need to change this is very intuitive), but ignored the adjustment of the feeder to relax the angle, then there will be the phenomenon of inaccurate feeding, the operator is not familiar with the feeder is often not think of the problem, at this time the operator will complain Said feeder is not good, can only apply to a kind of 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. Feeder feeding angle is generally within the range of 270 degrees to 350 degrees. Why should the angle of relaxation be so accurate? In fact, the reason for this problem is very simple, that is, each mold The stamping process is different, so the mold thickness, guide pin length is not the same, the change in the guide pin length will make the guide pin insert the material different time.

This time has changed. If the angle of relaxation is still according to the previous time, the clip loosening has not been correctly achieved, so that the guiding function of the pilot pin has not been 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.

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 achieve this correction, the feeder must be equipped with a relaxing device. With the realization, after the die guide pin tip enters into the stamping material, the feeder drum jamming material is just in a state of relaxation. At this time, the guide pin can correct the error in time, and this relaxation time is the angle of the feeder.
