Problems solved by technology

All of these increase the cost of equipment and limit the large-scale application of aluminum alloy hot forming.
[0004] Second, when forming deep-drawn parts, the area of ​​the sheet that first contacts the mold will cool rapidly, forming a hardened area that restricts the flow of the material, causing uneven deformation of the sheet, prone to stamping defects such as cracks and wrinkles, and reducing the material Formability
[0005] Third, after the aluminum alloy sheet is stamped, the parts will be subjected to pressure-holding and quenching treatment, which requires a long time (10-18 seconds) and a large pressure-holding power of the press
The general aging heat treatment time is 4-48 hours, which seriously reduces the production efficiency

Abstract

The invention discloses a light alloy plate stamping forming process and stamping device. The light alloy plate stamping forming process comprises the following steps that 1, a light alloy material isheated to the solid solution temperature of the light alloy material or above; 2, the heated light alloy material is placed between a female die and a male die; 3. the detection temperature of each area of the light alloy material is obtained; and 4, when the female die and the male die are closed for stamping, electric pulse treatment is carried out on the areas according to the detected temperature. According to the technical scheme, the production quality, the production energy efficiency and the production efficiency can be favorably improved.

Description

technical field [0001] The invention relates to the technical field of stamping and forming, in particular to a stamping and forming process and a stamping device for a light alloy plate. Background technique [0002] Aluminum alloy hot forming is an important technology to improve the lightweight level of automobiles. Its application in the stamping field of automotive sheet metal can make high-strength aluminum alloys that are difficult to process in the traditional sense, such as 2-series, 6-series, and 7-series, to be formed more quickly and have high strength. However, the current aluminum alloy thermoforming technology faces three major technical difficulties, which limit its application in the field of automotive sheet stamping. [0003] First, the temperature of the aluminum alloy sheet drops rapidly in the air and after contact with the mold, and the formability decreases. In order to solve this problem, a fast transfer mechanism must be used (for example, in some...
