[CN 202110564978.0] Locking Device and Method for Adjusting Die Height of Forging Press
[CN 202110564978.0] Title of Locking Device and Method for Adjusting Die Height of Forging Press: Locking Device and Method for Adjusting Die Height of Forging Press Application Number: CN 202110564978.0 Applicant: Rongcheng East China Forging Machine Tool Co., Ltd.; Central South University; Harbin Institute of Technology (Weihai); Shandong University; Xu Lin Application Date: 2021-5-24 Patent Type: Invention Application This invention relates to high-end equipment manufacturing industry, it specifically relates to a forging press die height adjustment locking device and method. The die height adjustment locking device includes a pre-tightening anti-loosening nut. Both ends of the pre-tightening anti-loosening nut are respectively provided with threaded holes, and both ends of the pre-tightening anti-loosening nut The side walls are respectively provided with locking parts, the locking part is provided with an axial open groove A, the open groove A communicates with the threaded hole, and the locking part is provided with a locking mechanism, the side walls at both ends of the pre-tightening anti-loosening nut are respectively provided with radial open grooves B, and the open grooves B are located inside the locking part and connected with it. The present invention makes full use of the metal elastic deformation theory and the above structure to realize the pre-tightening of the threaded connection in the axial and radial directions, and well solves the mechanical jacking technology of the mechanical press under the action of heavy load impact. The key technical problem that the lock nut structure used for adjustment between the upper pull rod and the lower pull rod is easy to loosen, which significantly improves the anti-loosening effect of the threaded connection and improves the reliability and stability of the mechanical jacking device.
