[CN 202110565058.0] Forging press lever type lower material adjustment device and method
[CN 202110565058.0] Title of Forging Press Lever Type Lower Top Material Adjustment Device and Method: Application Number of Forging Press Lever Type Lower Top Material Adjustment Device and Method: CN 202110565058.0 Applicant: Rongcheng East China Forging Machine Tool Co., Ltd.; Xu Lin; Sun Jianhua; Qiao aodong Application Date: 2021-5-24 Patent Type: Invention Application This invention relates to high-end equipment manufacturing industry, in particular to forging press lever type lower top material adjustment device and method, it includes a mold height adjustment mechanism and a lower top force automatic adjustment mechanism. The mold height adjustment mechanism includes an elastic pre-tightening anti-loosening nut. Axial and radial open grooves are respectively designed at both ends of the elastic pre-tightening anti-loosening nut. The locking part compresses the open groove to generate elastic deformation and continuous pre-tightening. The lower jacking force automatic adjustment mechanism includes a lever fulcrum seat and a guide rail to form a moving guide rail pair, the power unit drives the lever fulcrum seat to move accurately, and the locking unit locks the lever fulcrum seat. On the basis of the technical characteristics of good synchronization, symmetry and balance, large ejection force (more than 3 times higher than that of traditional technology), green energy saving and other technical characteristics, the efficiency and reliability are improved, the urgent requirements of precision forging extrusion or multi-station forging automatic production line and automatic control of precision die forging forming process are met, and the effect of automatic adjustment of forging extrusion force under precise control of forging press is achieved.
