Analysis of the instability of the bottom cover (thin plate) of the barrel
Text / Chen Dakui
Abstract: Mainly elaborated is the round thin plate (steel barrel bottom and cover) tensile parts. After a long time of stable stamping production, the quality of the product fluctuates, and the surrounding wrinkles appear, which is the phenomenon of instability. In this paper, by analyzing the stress change law of the blank deformation zone of the thin plate during the stamping process, looking for the factors that affect the tensile instability of the plate, and analyzing the reasons for the instability of the thin plate during the drawing process, it is helpful to determine the solution Problem approach.
Key words: stretching of thin plate; instability; stress analysis
