The solution of necking and pulling cracking of aluminum alloy stamping parts


1. Sheet aging control: The aluminum sheet has the characteristics of aging, with the increase of time, the strength and hardness increase, and the plasticity and toughness decrease. Due to the difference in the sheet metal manufacturing process, the state of delivery after heat treatment, transportation, temperature and other conditions, the mechanical properties of the aluminum sheet before stamping production are very different, which has a great impact on the production adjustment of the mold, and also causes frequent production during continuous production. There are problems such as necking and pulling. In order to solve this problem, we can first accumulate the range of mechanical properties that the mold can produce stably, and then use the aging characteristics of aluminum materials to master the aging rules, and place them out of use for aluminum materials with low yield strength to make them naturally age and increase the yield strength. To the expected range before production. 2. Early warning and interval supply of aluminum sheet mechanical properties By reforming the sheet material card, all the information of the sheet material is printed on the material card, which is convenient for quick comparison and analysis of material properties after production problems occur. In addition, the performance data of production problems are summarized and summarized to form its own performance warning range for each aluminum alloy stamping part. The use of blue card materials beyond the range plays a role in early warning of defects.
