Analysis of the factors that interfere with the accuracy of the width of the rewinder
1. During the operation of the rewinder equipment, if the tool has a problem of lateral swing, it will cause a bad size, such as the lateral swing of the tool and the difference in the outer diameter of the tool. Because the tool's lateral oscillation value cannot be zero. Generally, the lateral swing value of its load is about 0.03-0.05mm. The reason is the accuracy error of knife thickness, inner diameter, spacer width, etc., and the warpage caused by the lateral stress when the thick plate is sheared.
2. During the production of the rewinder equipment, due to the problem of lateral warpage of the steel plate, the width dimension is not good. This is because the product cut under the lateral warping state is larger than the set value of the knife.
3. Due to the production and operation of the rewinder equipment, there are corresponding matching errors in the spacer sleeves and cutters. Normally, the thickness accuracy of spacer sleeves and cutters is 0.005. When the number of blades is large, the accumulated error becomes larger. This is because the upper tolerance setting is not good. It should be understood that the width of the product cut by the rewinder is always slightly lower than the size of the product side with the knife. Therefore, it is necessary to predict the degree of this drop in advance. When arranging the knife on the product side, refer to the size of the spacer sleeve when confirming it.
