20230092104 · 2023-03-23 ·

A structure to apply flexing to an object to test resilience to being bent has a first portion and a second portion. The structure includes a base, a rotating member, a pressing plate, and an adjusting assembly. The base defines first and second receiving grooves, and the second receiving groove receives the first portion. The rotating member on the base is partially received in the first receiving groove. An abutting surface of the rotating member is recessed to form a third receiving groove which receives the second portion. The pressing plate on the base presses against the first portion. The adjusting assembly controls the rotating member to rotate towards the base about a desired angle, thereby causing the second portion to be bent with respect to the first portion.

Deformation limit evaluation method for sheared surface of metal sheet, crack prediction method, and press die designing method

There are provided an evaluation method and a prediction method for a technology to be reflected in a press die designing method. A deformation limit evaluation method includes evaluating the deformation limit on a sheared surface of a metal sheet in press-forming the sheared metal sheet. The deformation limit is evaluated and a crack in the sheared surface is predicted based on the relationship between an index value determined from two surface strain distribution gradients of a surface strain distribution gradient in a sheet thickness direction in the sheared surface and a surface strain distribution gradient in a bending ridge line direction by bending in a direction away from the sheared surface at an evaluation position among distributions of strains generated near the boundary between a bending outside surface and the sheared surface of the metal sheet to be bent and a tension generated in the sheared surface.
