Abstract

The present invention provides a shaping rate deciding method capable of deciding the shaping rate of a pressing apparatus properly and promptly. In the shaping rate deciding method for deciding the shaping rate of the pressing apparatus, a plate material is provided with a plurality of measurement points, and is pressed at a predetermined shaping rate by the pressing apparatus. Next, the distorted states (at points Q1 - QN) at the individual measurement points thus pressed are plotted in a shaping limit diagram containing a shaping limit line (FL) of the plate material, thereby to form a distortion distribution diagram. Of the points (Q1 - QN) plotted in the distortion distribution diagram, the point the closest to the shaping limit line (FL) is adopted as a specific measurement point. The shaping rate of the pressing apparatus is made lower than the predetermined shaping rate, in case the specific measurement point is located in an extended region (Epsilon2 > 0), but is made higher than the predetermined rate, in case the specific measurement point is located in a drawn region (Epsilon2 = 0).

Description

technical field [0001] The present invention relates to a forming condition determination method and a forming condition determination system for determining forming conditions of a press machine. Background technique [0002] Conventionally, it is known that in press working, the forming speed has a great influence on the quality of formed parts. Therefore, a pressing method and a pressing apparatus have been proposed which control the forming speed to prevent cracks, wrinkles, dimensional defects, etc. occurring in the formed product (for example, refer to Patent Document 1). According to the method and the press apparatus disclosed in this patent document 1, the forming speed is controlled so that the ratio of the movement amount of the upper die to the inflow amount of the material falls within a predetermined appropriate range. [0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-125355. [0004] However, a molded product having a complex shape ...
