Rod connection structure in multi-section activities

Abstract

The invention provides a multi-section movable medium rod connecting structure. The multi-section movable medium rod connecting structure comprises a medium rod, a first medium rod connecting bar anda second medium rod connecting bar from top to bottom, wherein the medium rod, the first medium rod connecting bar and the second medium rod connecting bar are connected with each other; the bottom end of the medium rod is provided with a medium rod base; the top end of the first medium rod connecting bar is provided with a first connecting structure; the medium rod base is movably arranged in thefirst connecting structure; the bottom end of the first medium rod connecting bar is provided with a connecting bar base; the top end of the second medium rod connecting bar is provided with a secondconnecting structure; and the connecting bar base is movably arranged in the second connecting structure. According to the multi-section movable medium rod connecting structure provided by the invention, by employing a structure of multi-section movable connection, the concentricity error of the medium rod and a die frame is eliminated, the medium rod is prevented from being broken by restraint,and the vertical concentricity error of the die frame meets the use requirement.

Description

technical field [0001] The invention relates to the technical field of powder compression molding, in particular to a multi-section movable middle rod connection structure. Background technique [0002] At present, when the existing powder compacting machine presses the product, there is a concentricity error in the upper and lower mold bases of the powder compacting machine. Before the powder compacting machine compacts the product, the concentricity error needs to be minimized. During use, it cannot be borrowed, and the concentricity error is large, and the middle rod is often broken, resulting in product pressing failure, increased production costs, and reduced production efficiency. Moreover, the existing middle stick cannot be shaken, which may easily cause the middle stick to be broken during use. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a multi-section movable middle rod connection structure, ...

Problems solved by technology

[0002] At present, when the existing powder compacting machine presses the product, there is a concentricity error in the upper and lower mold bases of the powder compacting machine. Before the powder compacting machine compacts the product, the concentricity error needs to be minimized. In the process of use, the position cannot be borrowed, the concentricity error is large, and the middle rod is often broken, resulting in product pressing failure, increased production costs, and reduced production efficiency.

Moreover, the existing middle stick cannot be shaken, which may easily cause the middle stick to break when used
