[0045] Its working principle is as follows: the bottom of the second push rod is against the corresponding position of the upper surface of the upper roller, and the material strip passes through the gap between the upper roller and the lower roller. Since the position of the lower roller is fixed, when the material strip exceeds the allowable tolerance range of the material thickness, the lifting amplitude of the upper roller is too large, and the bottom of the detection hole contacts the detection end. The detection alarm issues an alarm that the material strip is too thick and feeds back to the punch press to stop. The top of the detection hole contacts the detection end, and the detection alarm issues an alarm that the material strip is too thin and feeds back to the punch press to stop. The gauge is on the top of the second push rod, and the material thickness deviation can be directly seen. It is set in front of the stamping station of the stamping die to ensure that the thickness of all material strips entering the stamping station is qualified, thereby ensuring the normal and reliable production of products.
