Description

Technical Field

[0001] This invention relates to the field of plastic circular cross-section correction technology, specifically to a circular correction device for a large-diameter circular cross-section. Background Technology

[0002] With the upgrading of my country's production technology and the reform and development of the construction industry, many professions and fields have adopted large-diameter circular cross-section steel pipes. Compared with other cross-sections, circular steel pipes have better stability, and under the same strength and route conditions, circular cross-section steel pipes require less steel.

[0003] Because some large-sized pipes cannot be transported as a whole, they are assembled and welded at the point of use during production. The roundness of these large-diameter pipes, which are directly manufactured and welded, cannot meet the specifications, so they need to be rounded. However, the existing rounding devices cannot achieve multi-point correction, which not only reduces the correction accuracy but also increases the correction time, which is not in the best interest of the company. Summary of the Invention

[0004] The purpose of this invention is to provide a large-diameter circular cross-section straightening device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a large-diameter circular cross-section calibration device, comprising a fixed plate, a driven plate, an active plate, a lower slide rail for the calibration pin, an upper slide rail for the calibration pin, a calibration pin, a drive connecting rod, a right slide rail, a left slide rail, a combined support upright, a combined support crossbar, a combined support adjusting rod, a steering moving wheel slide rail, a steering pulley support, a steering auxiliary rod, a wheel, fasteners, a drive connecting rod connecting shaft, a driven plate shaft nut, a moving wheel slide rail, a pulley support, a hydraulic cylinder support, a hydraulic base fixing plate, and a hydraulic push rod. The fasteners include a first bolt, a second bolt, a third bolt, a fourth bolt, and a fifth bolt. The driven plate connects the drive connecting rod connecting shaft to one end of the drive connecting rod via the second bolt. The other end of the drive connecting rod connects the drive connecting rod connecting shaft to one end of the calibration pin via the second bolt. The lower slide rail and the upper slide rail of the calibration pin are fastened to the fixed plate by the first bolt.

[0006] Preferably, the steering wheel slide, steering pulley support, steering auxiliary rod, and wheel are connected to the crossbar of the combined support via a fourth bolt.

[0007] Preferably, the crossbar of the combined support is connected to the upright of the combined support and the adjusting rod of the combined support by a fourth bolt, and the upright of the combined support and the adjusting rod of the combined support are connected by the fourth bolt.

[0008] Preferably, the hydraulic cylinder support is welded to the fixed plate, and the hydraulic base fixing plate fixes the hydraulic push rod to the active drive plate by the fifth bolt.

[0009] Preferably, the right slide rail and the left slide rail are used to fasten the combined support column onto the fixed plate by a third bolt.

[0010] Preferably, the two sides of the fixed disk are respectively connected to a driven drive disk and an active drive disk via a driven drive disk shaft nut, and the active drive disk is connected to one end of the drive linkage via a drive linkage connecting shaft.

[0011] Preferably, the other end of the drive linkage is connected to a movable wheel slide via a drive linkage connecting shaft. One end of the movable wheel slide is secured to the right and left slides on the fixed plate by a third bolt, and the other end of the movable wheel slide is mounted on the pulley support by a fourth bolt.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] This invention moves the device to the position requiring correction, adjusts the height of the steering pulley support and pulley support according to the center height of the large-diameter cross-section, and uses the combined bracket adjustment rod to adjust the center of the fixed plate to be the same as the center height of the large-diameter circular cross-section steel pipe, with the fixed plate and the large-diameter circular cross-section steel pipe forming a 90-degree angle. Through the active drive plate, driven drive plate, drive connecting rod, and correction dowel rod, force is transmitted, so that the correction dowel rod is aligned with the large-diameter circular cross-section steel pipe. For local adjustments, the internal thread device of the correction dowel rod is used for adjustment, thereby completing multi-point correction. The correction of the required circular cross-section can be completed in one go, which can significantly shorten the correction time, reduce the difficulty of operation, and improve the safety of operation.
