HOT FORGING OF SEMIS FROM CYLINDRICAL BILLETS

摘要

FIELD: process engineering.SUBSTANCE: invention relates to blank production and can be used in press shop in production of semis. Blank is arranged in capsule with cylindrical wall and flat bottoms. Capsule is fitted in container pass through hole, container being mounted at press bed to displace axially thereat. Through hole length part features diameter corresponding to capsule wall OD. Bore features diameter corresponding to capsule wall ID on side facing the pressure male diameter. Axial force Pis applied by pressure male die with diameter corresponding to ID of capsule wall ID via one of capsule bottoms. Blank thrusts via second bottom on support male die. Force Pis applied to container in direction opposite that of force Papplication. Force Pis applied ion direction of force Papplication at termination of forging stage. Note here that P
