Stamping mould is in the process of cold stamping material (metal or non-metal) processing into parts (or semi-finished products), a special process equipment, known as cold stamping mould (commonly known as cold stamping mould). Stamping is a kind of pressure processing method, it uses the mold installed on the press to exert pressure on the material at room temperature, so that the material produces separation or plastic deformation, so as to obtain the required parts. Metal stamping factory tell you stamping mould maintenance skills are what?
 
mould loosening: movement of punch or mould exceeds unilateral clearance. Adjust the combination clearance.
 
Mold tilt: the mold or mold flatness is not correct, or there is a foreign body between the formwork, so that the formwork can not be smooth. Reassemble or grind to correct errors.
 
Formwork deformation: the hardness or thickness of the formwork is not enough, or the formwork is deformed by the impact of external force. Replace new template or correct disassembly method.
 
mould base deformation: mould base thickness or uneven force, guide post, guide sleeve straightness changes. Grind and correct or fill plastic steel or replace mold base or force average.
 
Mold interference: whether the size and position of the mold is correct, whether the positioning of the upper and lower mould is deviated, whether the assembly is loose, the accuracy of the punch, and whether the frame mold is correct.
 
Punching deformation: insufficient punch strength, large and small punch distance is too close, transverse force imbalance, punching half tilt. Strengthen the guide and protection of the peeled slant plate, or increase the punch, shorten the small punch, increase the heel and heel length, support and guide in advance, pay attention to the feed length.
