Steel pipe stop and feed device

Abstract

A steel pipe stop and feed device comprise an inclined beam and a lifting stop mechanism, wherein the lifting stop mechanism comprises a base, an upright post, a guiding base, a stop bar, a movable connecting sleeve, a cylinder, a lug; the upright post is fixed on the base, the guiding base is mounted on the upper section of the upright post, the stop bar is sleeved in the guiding base, the lug is fixed on the upright post or the base, a telescopic bar of the cylinder is in movably hinged connection with the stop bar through the movable connecting sleeve, the cylinder body of the cylinder is in movably hinged connection with the lug. Due to the steel pipe stop and feed device, the finished and leveled steel pipe can roll down from the inclined beam only through one lifting and conveying, the lifting stop mechanism can control the steel pipe to roll down simultaneously dependent on deadweight without the other lifting and conveying, thereby not only saving conveying time of the steel pipe one by one, but also saving energy, increasing the daily output of steel pipe cutting process by about 15%, and having remarkable energy-saving effect with 8kw saved per hour.

Description

Technical field: [0001] The invention relates to a material retaining device in a seamless steel pipe finishing production line, in particular to a material retaining device used in the sawing process in the seamless steel pipe finishing production line. Background technique: [0002] In the seamless steel pipe finishing production line, according to the production process requirements of hot-rolled air-cooled steel pipes, after the steel pipes are finished and straightened, the pipe heads that do not meet the standards at both ends must be cut off, so a sawing process must be set. With the application of wide-band saws, Multiple steel pipes can be sawed at one time. At present, steel pipes must be transferred from the finishing process to the sawing process twice through roller tables, inclined beams, and two sets of rotary arm material shifting devices, such as figure 1 As shown, the first group of pivoting arm shifting device 21 is installed beside the finishing conveyin...

AI Technical Summary

Problems solved by technology

In this kind of steel pipe input device, it is necessary to set not only a peach-shaped material stopper, but also two sets of rotating arm pulling devices. Therefore, the wide-band saw needs to wait for a long time for each cutting, and the working efficiency of the wide-band saw cannot be fully utilized, which not only affects the daily output of the steel pipe production line, but also consumes high energy consumption for the transportation of steel pipes.
