Abstract

The invention provides a hanging expansion rod structure and a pipe expansion machine with the same. The hanging expansion rod structure comprises an upper expansion rod fixing part, a lower expansionrod fixing part and a guide part; the upper expansion rod fixing part is provided with a first opening; the lower expansion rod fixing part is provided with a second opening; the upper expansion rodfixing part and the lower expansion rod fixing part are arranged at intervals; the guide part is arranged between the upper expansion rod fixing part and the lower expansion rod fixing part, and is provided with a third opening; the lower expansion rod fixing part is connected with the guide part; the upper expansion rod fixing part is movably arranged in the vertical direction; when the hanging expansion rod structure is in the hanging expansion rod state, the upper expansion rod fixing part is in contact with the guide part; and / or the upper expansion rod fixing part is connected with the guide part, the lower expansion rod fixing part is movably arranged in the vertical direction, and when the hanging expansion rod structure is in the hanging expansion rod state, the lower expansion rodfixing part is in contact with the guide part. The hanging expansion rod structure solves the problem of troublesome operation of a hanging expansion rod of a pipe expansion machine in the prior art.

Description

technical field [0001] The present invention relates to the technical field of tube expanders, in particular to an expansion rod hanging structure and a tube expander having the same. Background technique [0002] Tube expanders are widely used in the field of machinery manufacturing. They are mainly used to expand the diameter of the end area of ​​metal pipes. For tube expanders with different expansion rod suspension heights, when replacing the expansion rods, it is often necessary to replace the expansion rods Passing through the through holes on different boards, due to the gaps between the boards, it is difficult to align the expansion rods, making it difficult to hang the expansion rods. Usually, the operator needs to climb to the tube expander to perform the alignment operation of the expansion rods. Not only the operation is cumbersome, the speed of replacing the expansion rod is slow, but also there is a greater safety risk. Contents of the invention [0003] The...
