This study provides a basis for optimal V-shaped clamp mold surface design to enhance forming quality. By simulating the stamping process and optimizing the mold surface friction coefficient, the material flow velocity is improved. The results show significant regional characteristics in mold surface friction properties, with optimization leading to better quality of V-shaped clamp molding.
To improve the forming quality of V-shaped clamps, a basis for optimal V-shaped clamp mold surface design is provided. In this paper, the V-shaped clamp stamping process is simulated using Abaqus and the influence of the mold's friction coefficient on the V-shaped clamp stamping parameters is revealed. The regional friction coefficient of the V-shaped clamp mold surface is optimized using an equal horizontal design scheme and the optimal friction coefficient combination for the mold surface is obtained, along with comparison and analysis of the molding parameters before and after optimization. Results show that the mold's surface friction properties have significant regional characteristics. Increasing the friction coefficient of the bottom, the rounded section of the punch's V-shaped groove and the bulge filleted corner of the punch while reducing the friction coefficient of the bulge filleted corner and crimping area of the die head contributes to the material flow. Mold surface optimization makes the material flow velocity more uniform, disperses stress on the part's surface, reduces strain and thickness reduction of the key parts, and improves overall quality. Measurements show that the V-shaped clamp mold's surface friction characteristics affect the molding parameters significantly and mold optimization improves the V-shaped clamp's molding quality.
