Roller Feeder Leveling Feed Decoiler And Straightener For Metal Plate Roller


The roller feeder sometimes has a biasing phenomenon during the actual feeding process of the punching machine. The so-called biasing phenomenon is that when the roller feeder conveys the material, the material does not move along the parallel line with the feeder and the mold, but The phenomenon of skew between the feeder and the mold.


When the roller feeder is used with the punching machine, the quality of the finished product will not only be affected, but also the punching machine may be damaged and the stamping die may be damaged.


Therefore, once the biasing phenomenon occurs, the roller feeder operator needs to solve it in time, and the solution is to find the cause of the biasing phenomenon, so that normal production can be restored in time.


Ruihui machinery professional and technical personnel will explain the three reasons of the roller feeder biasing materials in detail:


1. The pressing force of the two left and right pressure adjusting springs on the top left and right of the roller feeder is relatively large, resulting in material deflection.


When the roller feeder is commissioned, the two pressing springs at the top need to be locked after the feeding, so that the material does not slip during the feeding process.


If the pressing force applied by the left and right pressing springs is large when the actual operation is performed, the material will move to the side of the roller with a relatively large pressure during the feeding process of the roller feeder, and this will cause our common deflection phenomenon.


The solution is very simple, just re-adjust the pressing force of the two-side pressing springs, so that the pressing force on both sides tends to be the same. Note that the pressing force should not be too large or too small, too much pressure on the material, too small will make the material slip. The pressing force is based on the fact that the material does not slip.


2. the mold is not installed positive, so that the roller feeder and the mold are not 90 degrees, resulting in skew phenomenon. In many cases, small molds are required on large tonnage punch presses, and small molds are easily skewed.


As a result, the feeder is not in the same line as the mold. At this time, the feeding is sure to be skewed. The solution is to re-adjust the mold installation position.


3. The material used in stamping production itself is not flat or has too many burrs, resulting in skewing.

The two rollers of the roller feeder are arranged in parallel, and they do not have the leveling function. If the material is not bent evenly, the feeding will be skewed.


At this time, the qualified material roll can be replaced or the leveling machine can be added in front of the feeder to level the raw material to the internal stress; if the material is too thick, the qualified new material roll must be replaced.
