Embodiment 1

[0031] Such as Figure 1-3 As shown, the present embodiment provides a cold and hot rapid cycle aging forming method for sheet metal, which includes the following steps:

[0032] Step 1. Put the solid solution treated sheet into the die horizontally, and then press the punch on the sheet;

[0033] Step 2, put the forming die 1 into the pressure device to apply pressure, so that the sheet material is tightly attached to the profile surface of the forming die 1, tighten the pressure-holding nut, and maintain the pressure of the forming die 1 on the sheet material;

[0034] Step 3, start the temperature control system, and enter the cooling and heating cycle aging forming process: at this time, the forming mold 1 is at room temperature, and the heating device is activated, so that the forming mold 1 is heated to a temperature slightly higher than the aging temperature;

[0035] Step 4. After reaching the set temperature, the temperature control system will turn off the heating d...

Abstract

The invention discloses a sheet metal cooling and heating rapid cycle aging forming method and device, relates to the technical field of sheet metal forming, comprising the following steps: horizontally put the sheet material after solid solution treatment into a concave die, and then press the male die on the sheet metal Put the forming mold on the pressure device to apply pressure, tighten the pressure-holding nut to maintain the pressure of the forming mold on the sheet; start the temperature control system and enter the cooling and heating cycle aging forming process: At this time, the forming mold is at room temperature, and the heating device Start to make the forming mold heat up to a temperature slightly higher than the aging temperature; after reaching the set temperature, the temperature control system will turn off the heating device and start the cooling device to cool the forming mold to room temperature; after the first cycle process is completed, it will enter a continuous cycle In the aging process, after the last cycle process is completed, the sheet can be taken out after cooling to room temperature, and the formed parts can be obtained. The invention reduces aging forming time, improves forming performance and has better forming effect.

Description

technical field [0001] The invention relates to the technical field of sheet material forming, in particular to a method and device for sheet material cooling and heating rapid cycle aging forming. Background technique [0002] Aluminum alloy sheets are processed into large curvature components through aging forming. As a key factor, the temperature in the aging process has an important impact on the quality of forming. The current research direction is mainly to increase the dislocation activation energy, increase the dislocation density, and improve the conversion rate from elastic deformation to plastic deformation by applying external energy and pre-deformation during the aging process. [0003] However, the existing aging forming requires a long forming time mainly due to the slow reduction process of the elastic stress of the material. [0004] Therefore, there is an urgent need to provide a new cold-heating rapid cycle aging forming method and device to solve the abo...
