Abstract

The invention provides an automatic control system used for a rolling force of a burring roller and a control method thereof. The automatic control system comprises a left burring device and a right burring device, wherein the right burring device comprise a second cylinder; the left burring device comprises a first cylinder; a pneumatic control unit is connected with the first cylinder and the second cylinder in a controlling manner; an electric control unit is connected with the pneumatic control unit in the controlling manner. The automatic control method comprises the following steps of: A, obtaining and recording thickness, yield strength, size, plastic deformation coefficient and hardness of a processed work-piece; B, inputting results obtained in the step A into the electric control unit; C, starting up the automatic control system, and starting controlling the automatic control unit after an electrical control reducing valve receives an electric control signal; D, adjusting the size of the rolling force between a movable pressing roller of the debugging device and a processing belt material based on the control result obtained in the step B, and displaying in a display screen. According to the scheme, the adjusted rolling force of the burring device is high in precision, the processing materials to be used are wide in range, and the rate of finished products in the processing process is extremely high; the automatic control system used for the rolling force of the burring roller and the control method thereof can be widely applied to the belt material processing field.

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...
