[CN 202110564944.1] Pressure Pin Air Flotation System and Method for Die Adjustment of Hot Die Forging Press
[CN 202110564944.1] Pressure Pin Air Flotation System and Method for Die Adjustment of Hot Die Forging Press Title: Pressure Pin Air Flotation System and Method for Die Adjustment of Hot Die Forging Press Application Number: CN 202110564944.1 Applicant: Rongcheng East China Forging Machine Tool Co., Ltd.; Harbin Institute of Technology (Weihai); Central South University; Shandong University; Sun Jianhua Application Date: 2021-5-24 Patent Type: Invention Application This invention involves high-end equipment manufacturing industry, specifically, it relates to a pressure pin air floatation system for mold adjustment of a hot die forging press, including a locking cylinder to lock or loosen a clamping rod, and a sensor to detect the locking and loosening state of the clamping rod; By inputting high-pressure gas into the upper and lower pressure chambers of the pressure pin, the pressure pin reaches a closed suspension state, and then the slider molding height is adjusted. The PLC controller is fully utilized to realize the interlocking of the pressure pin rotation and lock loosening detection. It solves the serious problem that the rotation of the pressure pin needs to overcome the static friction state when the hot die forging adjusts the die height of the slider, and the torque is large, which causes the copper sleeve to be quickly worn and injured and even the bevel gear pair, worm pair and coupling spline are twisted and damaged. It also solves the problem that the pressure pin clamp lock of the hot touch forging press and its automatic production line is tightly loosened and the pressure pin clamp lock is driven without detection control, effectively improve the transmission accuracy, automatic control, reliability and production efficiency of the hot touch forging press and its automatic production line.
