Novel press machine link mechanism

Abstract

Disclosed is a novel press machine link mechanism. A positioning flange is installed on a connecting link through bolts and fastening bolts. A lead screw is installed from the inside of a middle part hole of the positioning flange to the inside of a threaded hole of the connecting link. A shaft sleeve is arranged in the parts of the lead screw and a screw shaft, and the free size of the external diameter of the shaft sleeve is the same as the free size of a center unthreaded hole of the positioning flange. Due to the fact that the positioning flange can compulsorily ensure that the axis of the connecting link and the axis of the positioning flange are concentric, and thereby the defect that deformation occurs or even damage occurs among threads caused by the fact that the partial stress of the threads is excessive due to unbalance loading of stress of the connecting link is overcome.

Description

technical field [0001] The invention relates to a connecting rod mechanism, in particular to a novel press connecting rod mechanism, which belongs to the technical field of forging machinery. Background technique [0002] The connecting rod is an important functional part of the press. They transmit pressure by the cooperation of the internal and external threads of the two. At the same time, the adjustment of the working mechanism of the press is realized by the adjustability between the two threads. At present, in actual use During the process, it often happens that the thread between the two is difficult to adjust, and even the thread is damaged. Since the pressure transmission of the connecting rod is not always along the axis of the two, the stress between the threads occurs. Partial load, excessive local force, resulting in deformation or even damage between threads. Contents of the invention [0003] The object of the present invention is to provide a novel press l...
