Production deal with specific issues common
time2012/09/19
Encounter in the day-to-day production, punching is too large or too small (size may exceed the specification requirements) as well as the larger case, in addition to considering forming convex, die design, machining accuracy and punching punch size differenceclearance and other factors should also be considered from the following aspects to resolve.
⑴. The punching edge wear, the material suffered tensile stress increases stampings turned material distort the trend of increase. Produce material tumbling, punching size will tend to be small.
⑵. The extreme pressure of the material, so that the material is plastically deformed to cause punching increasingly large in size. Alleviate extreme pressure, punching size will tend to be small.
⑶ punch blade shape of the end. The end repair a slant or curved, blanking force slowing Stamping is not easy to produce material tumbling, twist, therefore, punching size increasingly large. The punch ends for the plane (no slant or curved), punching size relative will tend to be small.
Specific production practices for specific analysis should focus on specific issues, and to find a solution to the problem.
The above introduces punching, stamping material tumbling, twisted and Solutions.
