AI Technical Summary
In the flange plate coiler, the steel may be offset during the curling process due to different front and rear friction forces or the lifting deviation of the lower pressing roller, which will hit the frame of the plate coiler, causing damage to the frame.
A flange rolling machine anti-collision structure is designed, including setting up a press roller and an anti-collision roller group on the frame. The anti-collision roller group consists of an anti-collision frame, an anti-collision roller, an upper oil cylinder and a lower oil cylinder to prevent collision. The rollers and the press rollers are perpendicular to each other. The position of the anti-collision rollers is adjusted through the oil cylinder to adapt to steel of different widths, and a buffer plate is provided on the back of the anti-collision frame to prevent shock.
It effectively avoids direct collision between steel and frame, reduces friction with steel, prevents steel from getting stuck, and adapts to steel of different cross-sectional shapes by adjusting the position of the anti-collision roller, extending the service life of the frame.

Technical Field
[0001] The utility model relates to an anti-collision structure of a plate rolling machine, in particular to an anti-collision structure of a flange plate rolling machine. Background Art
[0002] The flange ring structure used in large offshore wind turbines is huge. Steel with a thickness of about 300 mm needs to be rolled by a plate rolling machine to be bent into a ring shape and then welded. During the rolling and curling process, the steel enters between the upper roller and the lower roller. The lower roller is continuously raised and lowered to bend the steel a little bit. During the adjustment process, the steel may be offset due to different front and rear friction forces or the lifting deviation of the lower roller, and hit the frame of the plate rolling machine, causing damage to the frame. Therefore, the frame of the plate rolling machine needs to be equipped with an anti-collision structure to avoid direct collision between the steel and the frame. Utility Model Content
[0003] In order to overcome the above-mentioned deficiencies, the utility model provides an anti-collision structure of a flange plate rolling machine to solve the above-mentioned problems.
[0004] To achieve this purpose, the structure adopted by the utility model is: the anti-collision structure of the flange rolling machine includes a frame, a pressure roller is arranged on the frame, a group of anti-collision roller groups are respectively arranged on both sides of the pressure roller, the pressure roller includes a group of upper pressure rollers and two groups of lower pressure rollers, the upper pressure roller is arranged above the lower pressure roller, the anti-collision roller group is arranged between the upper pressure roller and the lower pressure roller, the anti-collision roller group includes an anti-collision frame, the anti-collision roller is connected to the anti-collision frame, the anti-collision roller and the pressure roller are perpendicular to each other, and the anti-collision frame is connected to the frame.
[0005] An upper oil cylinder and a lower oil cylinder are respectively arranged on the upper and lower sides of the anti-collision frame, and the upper oil cylinder and the lower oil cylinder are respectively connected to the anti-collision frame through a connecting plate.
[0006] The back of the anti-collision frame is connected to the frame through bolts and nuts.
[0007] A buffer plate is arranged at the back of the anti-collision frame.
[0008] The beneficial effects are: the structural design of the utility model is reasonable and ingenious. During the feeding process of steel, the anti-collision roller on one side of the frame can prevent the steel from directly colliding with the frame, and the rolling anti-collision roller can reduce the friction between the steel and the frame to prevent the steel from being stuck after the collision. At the same time, the setting of the oil cylinder can adjust the front and rear positions of the anti-collision roller to adapt to the use of steel of different widths.

The anti-collision roller 35 and the pressure roller are perpendicular to each other. The anti-collision frame 33 is connected to the frame 1. The anti-collision roller group fills the contact gap between the steel feeding point and the frame. When the steel is offset when feeding between the upper pressure roller and the lower pressure roller, the anti-collision roller 35 can avoid direct collision between the steel and the frame 1 and reduce the friction between the steel and the steel, so that the steel continues to move forward smoothly.
