Automatic generation system and method of cut edge parts

Abstract

A method for automatically generating an edge cutting part comprises the following steps: selecting an outer contour line of a front view of an edge cutting part from a mold design drawing, and duplicating the outer contour line at the layer of the outer contour line; selecting a guide edge on the duplicated outer contour line; computing an straightening angle and a straightening center of the selected guide edge based on a coordinate system of the mould drawing when the selected guide edge tilts; computing a straightened rotation direction of the edge cutting part according to the computed straightening angle and the straightening center; straightening the contour line according to the computed straightening angle, the straightening center and the rotation direction; drawing a right viewand a bottom view of the outer contour line of the edge cutting part; drawing a fixation mode of the edge cutting part at an upper template in a 3D view of the edge cutting part; and drawing a concession hole on a lower template in the 3D view of the edge cutting part. In addition, the invention further provides an automatic generation system of the edge cutting part.

Description

technical field [0001] The invention relates to a system and method for automatically generating trimming parts. Background technique [0002] In the design of stamping dies, there are not only various types of trimming parts, but also each has its specific technical parameters and methods. It can be said that the design of trimming parts is a very complicated process. In the design process of trimming parts, the accuracy of parameters is difficult for the designer to control. For example, it is difficult for the designer to control the parameters with high precision such as the straight wall of the cutting edge. After the parameters are set, the compatibility between the parameters is almost impossible. Check it out manually; the design of interference algorithm and alignment algorithm involves a lot of mathematical knowledge and rules, and the probability of error is very high in practical applications. In the past, mold designers could only manually calculate and check t...

In the design process of trimming parts, the accuracy of parameters is difficult for the designer to control. For example, it is difficult for the designer to control the parameters with high precision such as the straight wall of the cutting edge. After the parameters are set, the compatibility between the parameters is almost impossible. Check it out manually; the design of interference algorithm and alignment algorithm involves a lot of mathematical knowledge and rules, and the probability of error is very high in practical applications

In the past, mold designers could only manually calculate and check the entire design process during the design process of trimming parts, resulting in waste of time, low precision, high error rate, and poor rationality.
