Embodiment

[0038] The key of the present invention is to establish a mold temperature database, including the temperature on the mold surface under combined conditions such as sheet metal geometric parameters, mold geometric parameters, water channel geometric parameters, and water channel flow velocity.

[0039] The present invention illustrates the implementation method of this invention through the analysis of the mold temperature on the section of an actual mold. Such as figure 2 As shown, for the whole part, using the same idea, more cross-sections can be taken, so that the mold temperature distribution of the whole part can be obtained.

[0040] Such as image 3 As shown, it is a section taken from a pair of molds, and the distribution of water pipes, plate thickness and other information can be seen.

[0041] Segment the section taken, and extract the information of each segment, including the diameter of the water channel, the distance between the water pipes, the distance bet...

Abstract

The invention relates to the technical field of hot stamping, in particular to a die profile temperature analysis method based on a database. The invention discloses a database-based mold surface temperature analysis method. The method is characterized in that the method comprises the following specific steps: S1, establishing a mold temperature database; S2, carrying out partitioning and geometric feature analysis on the actual molded surface; S3, calculating the temperature of each block; S4, displaying the temperature of each block; S5, determining the temperature change process and the pressure maintaining time. Compared with the prior art, the die surface temperature analysis method based on the database has the advantages that the die surface temperature database is utilized, the hot stamping die surface temperature can be rapidly analyzed, the dwell time needed under various cooling water channel designs can be determined, and a user can optimize the cooling water channel design of the hot stamping die according to the analysis result.

Description

technical field [0001] The invention relates to the technical field of hot stamping, in particular to a method for analyzing the mold surface temperature based on a database. Background technique [0002] Automated production lines are generally used to improve production efficiency for automotive hot stamping parts. Each punching process includes feeding, stamping, pressure cooling, and pick-up. Among them, pressure cooling is a quenching process, and the plate is taken away by cooling water on the mold. The heat on the material and mold. The holding cooling time has a decisive effect on the efficiency of hot stamping parts and the material after forming. The design of the cooling water channel on the mold, the flow rate of the cooling water channel, and the temperature and thickness of the sheet itself have an important impact on the time required for the mold to cool to a specific temperature. The analysis method of mold surface temperature is very important to the desi...
