Bảo trì Phương pháp Of Dập Chết

(1) Loose mold: the movement of the punch or die exceeds the unilateral clearance. Adjust the combination gap.
(2) Die tilt: The straightness of the punch or die is not correct, or there are foreign objects between the templates, so that the templates cannot be flattened. Rebuild or grind for correction.
(3) Biến dạng of the template: the hardness or thickness of the template is not enough, or it is deformed by external force. Replace with a new template or correct the disassembly method.
(4) Biến dạng của the khuôn base: the thickness of the mold base is inenough or the force is uneven, and the straightness of the guide post and guide sleeve varies. Grinding and correcting or refilling plastic steel or repplaceing the mold base or making the force equal.
(5) Die interference: whether the size and position of the die are correct, whether there is any deviation in the positioning of the upper and lower dies, whether they will loosen after assembly, the precision of the punching machine is not good, and the frame is not correct.
(6) Punching and shearing deflection: the strength of the punch is not enough, the size of the punch is too close, the lateral force is not balanced, and the punch is half-slanted. Strengthen the guiding and protecting effect of the stripping slant plate or enlarge the punch, shorten the small punch, increase the heel and heel length, support and guide early, and pay attention to the feeding length.
