Description

Technical Field

[0001] The invention relates to the technical field of steel pipe alignment devices, in particular to a stainless steel pipe alignment device. Background Art

[0002] Stainless steel pipe is a hollow long steel pipe. If the cross section is square, it is called square pipe. It is widely used as a pipeline for conveying fluids, such as oil, natural gas, water, coal gas, steam, etc. In addition, when the bending and torsional strengths are the same, the weight is light, so it is also widely used in the manufacture of mechanical parts and engineering structures. After cutting and trimming in production, the steel pipe needs to be sorted and bundled. The protruding steel pipe is easy to bump during transportation, which will cause damage to the steel pipe itself, and also cause damage to external people or objects. Therefore, the ends of the stainless steel pipe need to be aligned before bundling and packaging to avoid uneven steel pipes.

[0003] However, when the steel pipe is processed and transferred to the bundling equipment, it needs to be transported by a conveyor belt. Since the outer surface of the steel pipe is a cylinder, the steel pipe is easy to deviate on the conveyor belt, causing the steel pipe to tilt. The end of the steel pipe tilts when it contacts the alignment device, resulting in poor alignment of the steel pipe, affecting the subsequent bundling and packaging of the steel pipe; at the same time, the types of steel pipes are diverse, and the traditional alignment device is not equipped with a limit component to limit the position of different steel pipes, resulting in the steel pipes being transported scattered on the conveyor belt, requiring manual sorting, and the applicability of the device is poor; due to the different steel pipe processing equipment, the angle of conveying the steel pipe is also different. When some steel pipes are transported to the conveyor belt, the end of the steel pipe will scratch the conveyor belt, causing damage to the conveyor belt, affecting the service life of the conveyor belt. At the same time, the end of the steel pipe is easily damaged, affecting the quality of the product processed by the steel pipe. Summary of the invention

The card block 604 then The slider 601 is no longer engaged with the slot 605 on the connecting plate 405, and the slider 601 drives the plug plate 607 to slide. The fourth spring 610 contracts, and the plug plate 607 is no longer engaged with the slot 608 on the limiting plate 406. Then, the button 602 is released, and the third spring 606 is reset to drive the block 604 to engage in another slot 605. At this time, the slider 601 on the other connecting plate 405 can be slid down according to the same operation. After the two plug plates 607 are restricted on the limiting plate 406, the The limit plate 406 is pulled out from between the two connecting plates 405, and then a new limit plate 406 is replaced. Then, the pressing block 602 on the slide bar 601 is pressed, and the clamping block 604 is not engaged with the clamping slot 605. The fourth spring 610 is reset, driving the plug plate 607 to be inserted into the slot 608 on the new limit plate 406. Then, different limit plates 406 are replaced, which is convenient for limiting and separating steel pipes of different diameters. The setting of the guide shaft 609 improves the sliding stability of the plug plate 607 and prevents the fourth spring 610 from running off.

[0048] Secondly, when the angle of the guide plate 303 needs to be adjusted according to different transportation equipment, the pull ring 306 can be pulled, and the pull ring 306 drives the connecting rod 305 to slide, and the sliding of the connecting rod 305 drives the limit plate 307 to move, the first spring 311 is compressed, the limit plate 307 is separated from the guide plate 303, and the limit hole 308 on the limit plate 307 is separated from the limit column 309 inside the guide plate 303. At this time, the guide plate 303 can be rotated, and the guide plate 303 drives the rotating shaft 302 to rotate on the fixing bar 301. After rotating to a suitable feeding angle, the pull ring 306 can be released, and the first spring 311 is compressed. 11 resets and then drives the limit plate 307 to slide into the inside of the guide plate 303, and the limit column 309 is re-engaged in another limit hole 308. The setting of the guide bar 310 improves the sliding stability of the limit plate 307 and prevents the limit plate 307 from rotating. When it is necessary to replace different guide plates 303 according to steel pipes of different diameters, the pull ring 306 can be pulled to separate the limit plate 307 from the guide plate 303, and then the guide plate 303 is removed. The rotating shaft 302 can slide out from the notch set on the fixing bar 301. The setting of the first roller 304 makes the steel pipe transmission smoother.

[0049] Finally, after the steel pipe is transported on the conveyor belt 2, one end is under the limit plate 406, and the other end will conflict with the stop plate 705 inside the installation plate 702. The conveyor belt 2 continues to work until the steel pipes of the same batch evenly conflict with the stop plate 705, and then the second hydraulic rod 706 is started. After the second hydraulic rod 706 contracts, it will drive the stop plate 705 to rise, and the stop plate 705 slides in the slide groove 704, and the through-port 703 is exposed. At this time, the steel pipe will continue to be transported from the through-port 703 to the steel pipe bundling equipment. The setting of multiple through-ports 703 can also effectively separate and limit the steel pipes, thereby facilitating the subsequent transportation and bundling of the steel pipes, so that the same The ends of the steel pipes in the batch are always kept aligned. The setting of the fixed column 707 improves the sliding stability of the cut-off plate 705. When the mounting plate 702 needs to be replaced according to the diameter of the steel pipe, the driving block 802 on the handle 801 can be pressed, thereby driving the slide plate 803 to slide, and the fifth spring 807 contracts. The limit block 804 is no longer engaged with the limit groove 805 on the mounting frame 701. At this time, the handle 801 can be pulled to pull the mounting plate 702 out of the mounting frame 701, and then a new mounting plate 702 can be replaced. The setting of the fixed rod 806 improves the sliding stability of the slide plate 803 and prevents the fifth spring 807 from running off.
