Steel pipe nozzle circle calibration mechanism

Abstract

The invention provides a steel pipe nozzle circle correction mechanism, which includes two main plates, two hydraulic cylinders with linear displacement sensors, one mandrel, two pin shafts, six pairs of clamping blocks, one limit slider, and one support base , using the pulling force of the hydraulic cylinder to change the ellipticity of the steel pipe under the control of the sensor, it is more convenient, quick and safe to match a pair of steel pipes. When correcting the circle, align a pair of steel pipes with the nozzles on both sides of the mandrel respectively, one side of the short axis of the steel pipe nozzle is clipped into the clamping block, and the other side is clamped into the limit slider; a total of six pairs of clamping blocks are arranged, which can be respectively aligned with six Different diameters of steel pipes are used for round calibration; the lifting lug of the piston rod of the hydraulic cylinder is connected to the limit slider, and the lifting lug of the cylinder tube is connected to the main plate through the pin shaft, and the stroke can be controlled by the displacement sensor; the circle calibration mechanism is installed on the support base, and the support base The height can be adjusted to change the height of the mechanism; the support base is fixed by anchor bolts, which ensures the safety of the project and improves the reliability of the project.

Description

technical field [0001] The invention relates to a butt joint mechanism of a steel pipe nozzle, in particular to a circular adjustment mechanism of a steel pipe nozzle. Background technique [0002] Our country is vast and rich in resources, but the distribution of resources is uneven, and a series of problems of different energy demands in different places are bothering us. Therefore, energy transportation has become the key to solving this problem. Oil and gas transportation pipelines have been greatly developed in the past 40 years. This development momentum will continue in the next few decades, so the utilization of steel pipes has increasingly become indispensable in people's lives. After investigation, it is found that most of the production work of steel pipe assembly in China is done manually by workers. The assembly principle is: put the steel pipe on the V-shaped guide rail, use two iron wires staggered by 90° as the busbar, and when the distance between the steel ...

Problems solved by technology

However, due to the large diameter range and inconsistent length of the steel pipes that need to be assembled, the straightening and centering methods of the steel pipe joints are complicated, the overall production efficiency is low, and the error of the finished product is random, which affects the overall quality of the product.
