Stamping part springback predicting and monitoring method and system and storage medium

Abstract

The invention discloses a stamping part springback predicting and monitoring method and system and a storage medium, and the stamping part springback predicting and monitoring method comprises the steps: obtaining first data corresponding to a target mold molded surface and second data corresponding to a single stamping molded surface, and determining a target compensation value according to the first data and the second data, based on the target compensation value, constructing a springback value prediction model and / or monitoring the plate state, obtaining second data of a single-time stamping molded surface in the actual stamping process of the stamping part, determining the target compensation value by combining the first data corresponding to the target mold molded surface with the second data, and guiding stamping part machining according to the springback value prediction model. In this way, the machining mode for guiding the stamping part better meets the actual machining requirement, and / or the machining quality of the stamping part can be guaranteed by monitoring the plate state.

Description

technical field [0001] The invention relates to the technical field of stamping, in particular to a springback prediction and monitoring method, system and storage medium of a stamping part. Background technique [0002] The springback prediction, compensation and monitoring of sheet metal stamping parts are research hotspots and difficulties in the field of mechanical manufacturing and processing. [0003] The springback prediction of existing stamping parts is mostly based on the finite element analysis method. By setting the relevant attribute parameters of the plate, simulating the real processing environment, calculating the difference between the stamped surface and the target mold surface, and obtaining the compensation amount, it is used to guide the actual Processing, but the efficiency of this method is low. The compensation amount obtained is based on simulation, which has a large deviation from the real environment. As a result, when the stamping force is large, ...

Problems solved by technology

[0004] The main purpose of the present invention is to propose a springback prediction and monitoring method for stamping parts, a detection system and a storage medium, aiming to solve the problem that the compensation amount obtained based on simulation in the existing method has a large deviation from the real environment, resulting in When the stamping force is large, the damage and fracture of the plate cannot be monitored in time, which makes the processing quality of stamping parts poor
