What are the factors that affect the accuracy of the width and size of the rewinder

In the process of long-term use of the rewinder, there may be some failure problems, such as unstable product width and size. Below, let's take a look at the factors that affect the accuracy of the width and size of the rewinder.

1. In the process of running the rewinder, if there is a problem of transverse oscillation of the tool, it will lead to size problems, such as the transverse oscillation and the outer diameter size are different, because the transverse oscillation value cannot be zero. Usually the lateral oscillation value of its load is about 0.03-0.05mm. The reason is the accuracy error of thickness, inner diameter, spacer sleeve width, etc., and the warpage caused by lateral stress when the thick plate is sheared.

2. During the production of the rewinder, due to the problem of transverse warping of the steel plate, the width size is not good. This is due to the fact that the sheared article in the transverse warping state is larger than the set value when measured.

3. Due to the production and operation of the equipment, there are corresponding matching errors in the spacer sleeve. When the number of tool pieces is large, the cumulative error becomes larger, which is due to the poor setting of the upper tolerance. It is important to know that the width of the product sheared by the rewinder is always slightly lower than the side size of the product. Therefore, it is necessary to consider the size of the time spacer for the tool on the product side.
