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
The present invention relates to a kind of linkage, particularly a kind of novel press machine connection rod mechanism, belong to the metal forming machinery technical field.
Background technology
Connecting rod is the critical function parts of forcing press, they are by the cooperation transmission of pressure of both internal and external threads, simultaneously by the adjusting that realizes by the controllability between both screw threads forcing press operating mechanism, at present, the screw thread that usually occurs in the use procedure of reality between the two is difficult to regulate, the phenomenon that thread damage even occurs occurs, due to connecting rod at work the transmission of pressure be not always to carry out along both axis, so cause the stressed generation unbalance loading between screw thread, local pressure is excessive, even damages thereby cause deforming between screw thread.
Summary of the invention
The object of the invention is to: a kind of novel press machine connection rod mechanism is provided, overcomes the existing defects of existing linkage.
The technical solution adopted for the present invention to solve the technical problems is: a kind of novel press machine connection rod mechanism, it is arranged on locating flange above connecting rod with it with bolt, fastening bolt, be installed to leading screw in the screwed hole of connecting rod from the mider hole of locating flange, part at screw mandrel and silk axle, be provided with an axle sleeve, the external diameter free size of axle sleeve is identical with the free size of the center unthreaded hole of locating flange.
Beneficial effect: the axle center that can forcibly guarantee connecting rod due to locating flange is concentric with the axle center of himself, causes so the screw thread local pressure of having avoided connecting rod to cause due to stressed unbalance loading is excessive: the defective that deforms between screw thread and even damage.
