Formed punch design checking system and method

Abstract

The invention provides a punch design checking method, comprising the following steps: graphic elements to be checked are selected from die design drawing archives; whether the graphic elements have punch attributes: if the graphic elements have no punch attributes, the graphic elements which are going to be defined as punches are selected; a searching algorithm for the outer contour of a part isused for calculating outer contours of parts which are required to be designed with punches in the die drawing archives; when the graphic elements which are going to be defined as punches are not a plurality of closed polylines or concentric circles, whether an inclusion exists between the graphic elements and the outer contours of the parts is decided. The inclusion relation comprises coincidence. If no inclusion exists, the graphic elements are not designed into punches. If the graphic elements are a plurality of closed polylines or concentric circles, whether the outer contour of one part includes the central point of the graphic element is decided. If not, the graphic element is not designed into punch. A punch design checking system is also provided by the invention.

Description

technical field [0001] The invention relates to an inspection system and method, in particular to a punch design inspection system and method. Background technique [0002] In the field of stamping die design, a complete set of dies contains hundreds of parts, and each part contains a different number of punches. Designers often miss a few punches in the process of designing parts. There is no design, and it is almost impossible to find out whether there is a punch that has missed the design with the naked eye, and the size of the punch is also different, and it is difficult to find the small punches that have been missed. These situations can be roughly divided into two considerations: one situation is that a part includes multiple punches, and at this time, the designer may miss the design of relatively small punches, because the punches on some parts are very small, So that it is difficult to accurately judge whether there is a punch at this position with the naked eye; ...

[0002] In the field of stamping die design, a complete set of dies contains hundreds of parts, and each part contains a different number of punches. Designers often miss a few punches in the process of designing parts. There is no design, and it is almost impossible to find out whether there is a punch that has missed the design with the naked eye, and the size of the punch is also different, and it is difficult to find the small punches that have been missed.

These situations can be roughly divided into two considerations: one situation is that a part includes multiple punches, and at this time, the designer may miss the design of relatively small punches, because the punches on some parts are very small, So that it is difficult to accurately judge whether there is a punch at this position with the naked eye; another situation is that the design file contains many parts, but the parts are of different sizes, and the punch is even smaller for the smaller parts. , so that we cannot make accurate judgments with the naked eye
