technical field

The invention relates to the technical field of steel pipe forming, in particular to a steel pipe forming device with the function of correcting and positioning.

Background technique

Steel pipes are divided into seamless steel pipes and seamed steel pipes. Most of the seamed steel pipes are processed by steel pipe forming devices. The specific steps are as follows: first, leveling, then rolling, welding, and finally through trimming, cooling and Steel pipes are cut to form specific dimensions.

The technical solutions adopted by the steel pipe forming devices currently on the market are roughly similar to the technical solutions in the following patents "CN113695433A steel pipe forming equipment (disclosure date 2021.11. 26)", "CN215355520U steel pipe forming die (disclosure date 2021.12. 31)" , but in actual work, the following problems are often encountered: first, the steel belt sometimes deviates due to external factors or the factors of the machine itself during the movement, and the existing steel pipe forming device usually does not have Correct the positioning function, and then affect the subsequent processing; second, according to the national standard, the width of the steel strip has a certain allowable deviation. As the width of the steel strip increases, the allowable deviation will also increase. The belt is used directly without treatment, which causes the quality of the product to be unstable, and is not conducive to improving the quality of the product; third, the steel belt will form a tube blank after being rolled, and the tube blank will be formed into a steel pipe when it passes through a high-frequency welding mechanism At this time, the surface of the steel pipe will carry welding lumps. At present, the steel pipe forming device usually directly uses a scraper to remove the welding lumps.
