Abstract
The invention discloses a method for scratch forming by using an automatic scratch forming device for coating corrosion resistance testing. The method includes the steps that a scratch cutter clamping block is jacked up through an air cylinder to drive a scratch cutter to move upwards, and at the moment, a spring is stretched; a workpiece with a coating is placed below the scratch cutter, a piston rod of the air cylinder shrinks to drive the scratch cutter clamping block to descend so as to drive the scratch cutter to press downward to the surface of the workpiece to press a scratch; the scratch cutter is raised, a rotating disc is rotated, the rotating angle of the scratch cutter can be seen through scales on an annular scaleplate, when the scratch cutter is rotated to the needed angle, the scratch cutter clamping block is descended, and the scratch cutter presses downwards to form a scratch on the surface of the workpiece again so that the intersecting scratches can be formed. The method has the following advantages that the cross intersecting scratches are automatically formed in the coating on the surface of the workpiece, the intersecting angle of the scratches can be adjusted according to needs, and the angles and the depths of the intersecting scratches are accurate; the lengths, widths, depths and angles of the different coating scratches can be kept highly uniform; the width, the depth and the angle can be adjusted according to needs. The problems that manual scratch forming wastes time and labor, and the scratches are not uniform are solved, and the working efficiency is improved.
