Description

Technical Field

[0001] The utility model relates to the technical field of finishing rolling bending roll straightening, in particular to a finishing rolling bending roll straightening device. Background Art

[0002] Finished steel pipe, also known as cold-rolled precision steel pipe, is a production process for seamless steel pipe. It is one of the higher-end varieties of seamless steel pipe and is characterized by high precision and surface finish requirements. This is especially true for seamless steel pipes used in oil cylinders, which have even higher quality requirements. This type of steel pipe can withstand high pressure and does not crack or wrinkle during deformation processes such as cold bending, flaring, and flattening. It can undergo various complex deformation and machining processes. Straightening is generally required during the production process.

[0003] Patent No. CN221246547U discloses a finishing bending roll straightening device, comprising a cabinet with a support plate fixedly provided on the top of the cabinet. The device is equipped with a feeding mechanism. When in use, a first electric telescopic rod drives the first housing to move downward, and a first gear and a second gear drive the first rotating rod and the second rotating rod to rotate via a first chain and a second chain, thereby causing the first pressure roller and the second pressure roller to drive the finishing tube into the straightening mechanism. The device is also equipped with a discharging mechanism. When in use, a third gear and a fourth gear drive the third rotating rod and the fourth rotating rod to rotate via a second chain and a third chain, thereby causing the third pressure roller and the fourth pressure roller to drive the finishing tube out of the straightening mechanism. The device is also equipped with a straightening mechanism. When in use, a first cylinder drives the first baffle to move toward the second baffle, and a second cylinder drives the second baffle to move toward the first baffle, thereby clamping the finishing tube and straightening it.

[0004] But the following problems still exist:

[0005] When the first baffle and the second baffle of the above-mentioned device clamp the finished rolled tube for straightening, the force generated during clamping and straightening may cause certain obstructions to the first pressing roller, the second pressing roller, the third pressing roller and the fourth pressing roller in conveying the finished rolled tube, and then the finished rolled tube may stagnate on one side of the straightening device and cannot smoothly leave the straightening mechanism, which is quite inconvenient.
