[0018] like Figure 1 As shown in FIG. 3 , a specific implementation of a sun visor flanging welding device is as follows:

[0019] It includes a base plate 1 and a fixing frame 3. A pair of fixing shafts 2 are arranged on the base plate 1. The fixing frame 3 is arranged on the fixing shafts 2. The upper part of the fixing frame 3 is in a square shape. The lower part of the fixing frame 3 is a fixing block fixed on the fixing shafts 2.

[0020] A pressing plate fixing plate 6 is fixedly provided at the front end of the top of the fixing frame 3, and a pair of front pressing plates 62 and rear pressing plates 61 are provided on the pressing plate fixing plate 6. The front pressing plates 62 and the rear pressing plates 61 are arranged adjacent to each other to form a 90° corner pressing plate, and the rear pressing plate 61 is T-shaped.

[0021] A pair of guide bearings 7 are provided on each group of front pressing plates 62 and rear pressing plates 61, and a guide waist hole corresponding to the guide bearings 7 is provided on the pressing plate fixing plate 6. The guide hole has a certain angle with the direction of the film pushing cylinder and faces the direction within the right angle of the corner pressing plate.

[0022] A separation bearing 9 is arranged in the middle position of a pair of the front pressing plates 62 and the rear pressing plates 61, a downward pressure cylinder 4 is arranged on the fixed frame 3, a film pushing cylinder 5 is arranged on both sides of the fixed frame 3, a pushing plate 31 is arranged in front of the output shafts of the two film pushing cylinders 5, a rear pressing plate contraction spring 10 is connected between the two rear pressing plates 61, a rear pressing plate guide block 1 8 and a rear pressing plate guide block 2 11 are arranged on both sides where the rear pressing plate 61 is fixed to the pressing plate fixing plate 6, a front pressing plate contraction spring 12 is connected between the two front pressing plates 62, a front pressing plate guide block 13 and a front pressing plate guide block 2 14 are arranged in front and behind the fixed sides where the front pressing plate 62 is fixed to the pressing plate fixing plate 6.

[0023] When working, the film-pushing cylinder 5 works, and the output shaft of the film-pushing cylinder 5 pushes a pair of front pressing plates 62 and rear pressing plates 61 forward. The front pressing plates 62 and rear pressing plates 61 are automatically separated under the action of the guide bearing 7 and the separation bearing 9, and the film is pushed inward. Due to the separation of the front pressing plates 62 and rear pressing plates 61, it is ensured that the film will not be wrinkled at the corners.

[0024] The film pushing cylinder 5 contracts the front pressing plate 62 and the rear pressing plate 61, and they return to their original positions under the action of the two contraction springs.
