s4: after the small-sized primary processing die steel is clamped by the four detection plates (14), the servo motor (4) is closed, lines drawn by the marking pen (22) on the detection ruler (15) are checked, if the lengths of the lines on the two detection rulers (15) on one side are different, the fact that the area on one side of the small-sized primary processing die steel corresponding to the detection plate (14) on the side is uneven is shown, if the lengths of the lines on the two detection rulers (15) on one side are the same, the fact that the area on one side of the small-sized primary processing die steel corresponding to the detection plate (14) on the side is flat is shown, and at the moment, only a certain area on one side of the;
s5: when the whole side of the small-sized primary processing die steel is to be detected, a magnet is arranged on a push plate (20) corresponding to a cylinder (18) on one side, then the cylinder (18) is started to extend an expansion rod (19), so that the magnet on the push plate (20) absorbs the top end or the side of the small-sized primary processing die steel, then the cylinder (18) is continuously started to start intermittently, namely the expansion rod (19) extends a small section at intervals, at the moment, the small-sized primary processing die steel moves towards the direction, so that different areas on the side of the small-sized primary processing die steel are in contact with detection plates (14) on two adjacent sides of the started cylinder (18), and further, the flatness detection is carried out on the different areas on the two sides of the small-sized primary processing die steel;
s6: starting another air cylinder (18), detecting the flatness of different areas of the side surfaces of the other two sides of the small-sized primary processing die steel according to the step S5, and repeating the steps to detect the flatness of four side surfaces of the small-sized primary processing die steel in the horizontal direction;
s7: turning the small-sized steel bar of the primary processing die to enable the top end and the bottom end of the small-sized steel bar of the primary processing die to be turned to be parallel to the detection plate (14), and then detecting the flatness of the top end and the bottom end of the small-sized steel bar of the primary processing die according to the method;
and S8, after all six surfaces of the small-sized primary processing die steel are detected, starting the servo motor (4) to reversely rotate so that the four detection mechanisms move towards the outer side, taking out the small-sized primary processing die steel, and closing the servo motor (4).
