Test Results of Forging Medium and High-pressure Valve Bonnets
4. Analysis of test results (1) The problem of thin forging at the top: When the thickness of the blank is certain, it is possible to make the top size of the workpiece thinner by forging. Under our experimental conditions, when the thickness of the blank is less than 6 to 7mm, thin forging will be difficult. For the pre-forged thin bad material, place it on the forming die. On the one hand, the workpiece is thin and heats up quickly; on the other hand, it is in contact with the mold at a lower...
