For has 18 years experience in stamping processing industry, if you want to do a good job in stamping processing this will understand the importance of mold, and mold manufacturing, we early also speak more for mould maintenance less instead, authors and today we popularize knowledge of some simple stamping processing die maintenance!
Stamping processing die is usually used after a certain time to mold maintenance, so-called mold maintenance, usually if the punch material biting, take not to come out, please click the following project inspection.
1, stamping processing punch and die grinding again.
Sharp edge of the mould can work out a beautiful cut surface, the blade is blunt, requires additional pressure, and rough workpiece cross section, produce very big resistance, grabbed the punch was stuff.
2, stamping processing and die clearance.
Die clearance if relative thickness is not suitable, punch takes a lot of ejection force when out of the material.
If it is for this reason the punch is material biting, please replace the reasonable gap lower die.
3, stamping processing material status.
Material stained, or dirt, dirt attached to the mould, make the punch was biting and will not be able to process the material.
4 a deformation of the material, stamping parts.
After warping of the material in the hole, can clamp the punch, punch was biting.
Materials have a warp, please flat after processing.
5, the overuse of spring.
Will make the spring fatigue.
Please always pay attention to check the performance of the spring.
