Abstract
Description
technical field
[0001] The invention relates to the technical field of metal strip processing equipment, in particular to an automatic control system and a control method for the rolling force of a deburring roll. Background technique
[0002] Strip trimming disc shears are generally set on the finishing line. Because the blade is a rotating disc, it can continuously cut the moving strip. The strips that need to be trimmed include mild steel, high-strength steel, and stainless steel. For steel types such as silicon steel and tin plate, under reasonable shear conditions, the burr height is generally 5% of the plate thickness, and the burr requirement is less than 0.01 mm under the condition of using deburring rollers. When the strip is relatively thin, And when the yield limit of the strip is very low, the minimum limit of the rolling force required for deburring can be zero at this time, and once the pressure is too high, it will leave indentations on the finished strip, but...
