Embodiment Construction

[0077] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings, but the protection scope of the present invention should not be limited thereby.

[0078] refer to figure 1 , the generation method of the stamping die drawbead of the present embodiment may include the following steps:

[0079] Step S11, define the drawbead centerline, punching direction, binder surface, drawbead height and die fillet radius, and select from a variety of preset drawbead types, the preset multiple The drawbead type contains the following information: width, bead gap value, and root fillet radius;

[0080] Step S12, translating the binder surface along the stamping direction, and the translation distance is the height of the drawbead, so as to obtain the bottom surface of the concave bead;

[0081] Step S13, translating the bottom surface of the concave rib along the opposite direction of the stamping direction, and the translation ...

Abstract

The invention provides a generating method and system for a stamping die brake bead and a modification type brake bead. The generating method of the stamping die brake bead comprises the following steps: defining a center line of the brake bead, pressing direction, binder surface, height of the brake bead and die stripping corner radius, selecting from a plurality of preset brake bead types, translating the binder surface in the pressing direction to obtain a concave brake bead bottom surface, translating the concave brake bead bottom surface in the reverse direction of the pressing direction to obtain a convex brake bead top surface, stretching the center line of the brake bead, respectively shifting the stretched sheet to outside and inside to obtain two side wall surfaces, conducting circular bead operation to the two side wall surfaces, the convex brake bead top surface and the binder surface to obtain the convex brake bead molded surface, conducting the circular bead operation to the two side wall surfaces, the concave brake bead bottom surface and the binder surface to obtain the concave brake bead molded surface. The generating method disclosed by the invention can automatically finish modeling of the brake bead according to the related parameters inputted by a user, and is favorable to shorten the design cycle and lower the cost.

Description

technical field [0001] The invention relates to the design of drawbeads of stamping dies, in particular to a method and system for generating drawbeads of stamping dies and modified drawbeads. Background technique [0002] In the drawing process of stamping parts, in order to better control the material flow and sheet forming, it is necessary to set drawbeads in the stamping die used in the drawing process. [0003] Usually, in the design process, the parameters of the drawbead are standardized, and there are preset fixed parameter values ​​for the width of the drawbead and the fillet at the bottom. In the prior art, the modeling of the drawbead is mainly completed by manual modeling, for example, it is manually completed under the Catia platform. However, the manual modeling method takes a long time and has a large workload, resulting in a long mold design cycle and high cost. Contents of the invention [0004] The technical problem to be solved by the present invention...
