Description

Technical Field

[0001] The present invention belongs to the technical field of micro-texture processing, and in particular relates to a design system, terminal, equipment and medium for micro-texture on the surface of a stamping die. Background Art

[0002] Currently, stamping dies are essential tools for plastically deforming sheet metal during the stamping process. The surface treatment technology used in these dies determines the quality of the formed workpiece. During the stamping process, the die has a large contact area. Furthermore, the deformation of the sheet metal during flanging is accompanied by enormous deformation forces, which makes it easy for intense friction to occur between the concave and convex dies and the sheet metal. Prolonged friction can easily lead to die wear and reduce die life. Microtexturing the surface of stamping dies can improve the friction and wear properties of the die surface, thereby increasing die life and workpiece forming quality. Laser surface microtexturing is currently the most widely used surface microtexturing technology. It offers advantages such as ease of processing, high processing efficiency, high precision, a wide range of processing targets, and controllable texture geometry and morphology. However, improperly designed surface microtextures can also have negative effects. Therefore, optimizing the design of surface microtextures is key to improving friction and wear properties.

[0003] There is no method in the existing technology that can realize micro-texture simulation, and the quality and effect of existing micro-texture design cannot be guaranteed.
