Abstract

The present application belongs to the technical field of stainless steel processing, and provides a method for solving the leveling pad paper printing defects of 430 stainless steel cold plate thin material, which comprises the following steps: the actual paper tension during the acceleration and deceleration of the motor of the leveling machine is 80% of the given paper tension; during the threading process, two machine front workers use a crowbar to pry the strip head in cooperation with the main operator to ensure that the strip head does not deviate; the use of corrugated paper is controlled at 1-2 sheets; and the operation process of the leveling machine is optimized; through the improvement of the equipment and process parameters, the functional accuracy of the leveling machine group of the company is improved, the one-time unqualified rate of the leveling pad paper printing of the 430 stainless steel cold plate thin material is obviously reduced, the operation efficiency of the leveling machine group is improved, the production cost is saved, the customer objection rate is reduced, and the customer satisfaction is improved.
