某产品拉伸件内膛重皮疵病的克服
Analysis and Solution to the Lap Defect in the Bore of a Draw Part
The causes of the lap defect in the bore of a draw part is introduced. By decreasing the lubricant concentration, adjusting the ability of water under high pressure to remove scale and optimizing the punch structure, the lap defect in the bore is completely overcomed. The economic and social benefits are produced. It provides reference for heavy calibre projectile draw part production.
