Description

[0002] Wind turbine tower is the tower of wind power generation, which plays a supporting role in wind turbine generator set. Wind turbine tower is mainly made of plate steel by plate rolling machine. However, traditional plate rolling machine is not convenient to adjust the angle of plate rolling, and it is not convenient to separate the roller from the steel structure product after the plate rolling is completed. Traditional equipment and steel structure products will cause damage to the plate rolling machine, reducing the service life of the plate rolling machine.

[0003] The publication (announcement) number is CN217990501U, which discloses a plate rolling machine for steel structure production, including a workbench, one side of the workbench is fixedly connected to a mounting frame, a plate rolling machine body is arranged inside the mounting frame, and the plate rolling machine includes a bending part, and a bending cavity is opened on one side of the bending part. The advantage of the utility model is that the utility model can reduce the damage of the steel body to the inner wall of the bending part through the auxiliary device provided, and the two clamping plates can be clamped on one side of the steel body. The wheels provided on one side of the two clamping plates can protect the inner wall of the bending part during the bending of the steel body, and can also play a role in assisting the bending. When the steel body is pushed forward under the action of the telescopic cylinder, the steel body enters the interior of the bending part, and the wheels will move along the inner wall of the bending part, so that the steel body can be bent more quickly, saving a lot of time.

[0004] Although the above scheme can install guide wheels on the end faces of the steel body that push the bending parts to assist the rolling process and perform multi-point positioning of the steel body, the position of the limit plates positioned on both sides of the steel body is fixed and difficult to adapt to the width of the steel body, and the baffle positioned on the top of the steel is also difficult to adapt to the thickness of the steel body through bolt fixation. The adjustment and adaptation range of the limit components of the equipment during the bending processing of wind turbine tower steel is limited and the practical effect is general. For this reason, we propose a steel bending device for wind turbine tower processing. Utility Model Content
