There are many problems in the production of automobile stamping parts

The automobile stamping die represents the generalization that can be classified into the basic figure. First, search whether there is a stamping die that is completely common with the generalization and can be rushed out with a stamping action in the stamping die library. If there is such a die, the stamping die set under "select stamping die" will be neglected, and the searched stamping die will be directly used.

The system will select stamping dies according to the following criteria:

1For the generalization that can be classified into the basic figure, first search whether there is a stamping die that is completely common with the generalization and can be produced by a stamping action in the stamping die library. If there is such a die, the stamping die set under "select stamping die" will be neglected, and the searched stamping die will be directly used.

2. For rectangle generalization, when the long side is greater than or equal to 1.5 times of the short side, it will actively search whether there is a square stamping die common with the short side of the rectangle; for long circular groove or circular groove, it will search whether there is a circular stamping die with the same groove width, if there is one, it will be directly used. If the above two steps do not determine the stamping die, then consider using square or circular stamping die to step the straight line or arc.

3. First, consider the die set under "select stamping die", analyze whether the straight line to be punched is greater than or equal to 1.5 times of the side length of the die for the set square die, and analyze whether the diameter of the arc to be punched is greater than the diameter of the die for the inner side of the stamping curve of the circular die. If so, use the set die.

4. If the set die is not suitable, the system will search for square or circular die from small to large in the stamping die library, and use the straight line satisfying to be pressed to be greater than or equal to 1.5 times the side length of the die.

There are many problems encountered in the production of stamping die, one of which is the uneven cutting edge. What causes the uneven cutting edge of stamping die?

One: uneven trimming can be caused by positioning offset. We just need to adjust the positioning.

Two: planning fault, forming uneven connection, need to cut edge inserts from scratch to deal with.

Three: it can also be caused by forbidden feeding. We just need to adjust the feeder.

Fourth: it can also be caused by the wrong calculation of the feeding step. At this time, we need to check the step from the beginning and reset the tool position.

The uneven cutting edge of stamping die can be formed by the above four reasons. We must find the right reason in the operation to deal with it in time.
