How to solve the problem of uneven trimming of automobile stamping dies?

Automobile stamping dies represent the generalization that can be included in the basic graphics. First, go to the stamping die library to search whether there is a stamping die that is completely consistent with the generalization and can be punched out of the generalization with one stamping action. If there is such a die, the stamping die set under "Select Stamping Die" will be ignored, and the found stamping die will be used directly.

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

1. For the outline that can be included in the basic graphics, first go to the die library to search whether there is a stamping die that is completely consistent with the outline and can be punched out of the outline with one stamping action. If there is such a die, the stamping die set under "Select Stamping Die" will be ignored, and the found stamping die will be used directly.

2. For the generalization of rectangles, when the long side is greater than or equal to 1.5 times the short side, it will automatically search for a square stamping die that is the same as the short side of the rectangle: for long round grooves or round grooves, search for a circle with the same groove width If there is a stamping die, use the die directly. When the punching die has not been determined through the above two steps, consider using a square punching die or a circular punching die to punch a straight line or an arc.

3. First consider the stamping die set under "Select Stamping Die", analyze whether the straight line to be stamped is greater than or equal to 1.5 times the side length of the stamping die for the set square die, and analyze the line to be stamped when the circular stamping die is inside the stamping curve Whether the arc diameter is larger than the die diameter. If so, use the set die.

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

There are many encounters in the production of stamping dies, and uneven trimming is one of them. What are the reasons for the uneven trimming of stamping dies?

One: The uneven cutting edge can be caused by positioning offset, we only need to adjust the positioning.

Two: The design is wrong, resulting in uneven knife connection, which needs to be solved by re-cutting the edge and edge inserts.

Three: It can also be caused by improper feeding, we only need to adjust the feeder.

Four: It may also be caused by incorrect calculation of the feeding step distance. At this time, we need to recalculate the step distance and re-set the knife position.

The uneven trimming of the stamping die can be caused by the above four reasons. We must find the right reason in the operation in order to solve it in time.
