Problems solved by technology

[0004] For the above-mentioned related technologies, the inventor believes that there are the following defects: the alignment of the mandrel and the mandrel is all aligned by human inspection, and it is also necessary to manually push the mandrel to apply an axial force to the mandrel, so the work The strength is huge, which will take more time and reduce the efficiency of connecting the mandrel and the mandrel

Abstract

The invention relates to a large-diameter seamless tube core rod rapid mounting device and a using method. The large-diameter seamless tube core rod rapid mounting device comprises a base and an ejector rod, a mounting system is arranged on the base and comprises a first sliding seat, a clamping mechanism, a moving mechanism and a driving mechanism; the first sliding seat is arranged on the base in a sliding mode and is used for supporting a core rod; the clamping mechanism is arranged on the first sliding seat and is used for clamping the core rod; the moving mechanism is arranged on the baseand is connected with the first sliding seat; the driving mechanism is arranged on the base and is detachably connected with the ejector rod. According to the large-diameter seamless tube core rod rapid mounting device and the using method, the core rod is clamped through the clamping mechanism, the moving mechanism drives the core rod to get close to the ejector rod, the driving mechanism is started to enable the core rod to be in threaded connection to the ejector rod, so that the core rod and the ejector rod are connected together, whether the core rod is aligned with the ejector rod or not does not need to be judged manually, thus the core rod does not need to be pushed manually, therefore the working intensity of workers is relieved, time is saved, and the connecting efficiency of the core rod and the ejector rod is improved.

Description

technical field [0001] The present application relates to the technical field of mandrel installation, in particular to a large-diameter seamless tube mandrel quick installation device and a method of use. Background technique [0002] In the seamless steel pipe rolling process, the mandrel and the ejector are tooling that needs to be used, and the size of the mandrel and the ejector is large, and there are many types of specifications. In order to facilitate replacement, the mandrel and the ejector are threaded. For connection, the mandrel is provided with a threaded column, and the ejector rod is provided with a threaded groove, and the threaded column is threadedly connected with the threaded groove. [0003] In the related technology, the gravity of mandrel and ejector rod is relatively heavy, so for the convenience of connection, two cranes are currently used for connection, that is, one crane uses a sling to fix the mandrel and lift it to a certain height from the grou...
