DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Example 1

[0022] Reference Figure 2 , 3 , 4 and 6, a door shell window bending and forming equipment, including a base 4, a first fixing frame 5 and an operating table 6, the first fixing frame 5 is fixed on the base 4 and the operating table 6, a groove is provided at the center of the operating table 6, the groove is used to place the door shell window to be bent, the groove is used to limit the position of the door shell window to be bent on the operating table 6, to ensure the accuracy of the position of the door shell window to be bent during bending, a hole 7 is penetrated on the operating table 6 in the groove, a second electric telescopic rod 12 is fixed on the base 4 directly below the hole 7, a push plate 13 is fixed on the second electric telescopic rod 12, the hole 7 is for the push plate 13 to pass through, and the size of the push plate 13 is smaller than the size of the window 2, providing bending space for the bending of multiple protruding blocks 3, to ensure the smooth bending of multiple protruding blocks 3;

[0023] A positioning mechanism is fixed on the operating table 6, and the positioning mechanism includes a second fixing frame 8, a first electric telescopic rod 9 is fixed on the second fixing frame 8, a third fixing frame 10 is fixed on the first electric telescopic rod 9, and a lower pressing frame 11 is fixed on the third fixing frame 10. The lower pressing frame 11 is arranged just above the groove, and the first electric telescopic rod 9 is used to drive the lower pressing frame 11 to move downward until the lower pressing frame 11 is pressed on the door shell window that needs to be bent in the groove. When the multiple protruding blocks 3 are pushed and bent by the push plate 13, the multiple bent protruding blocks 3 will be attached to the inner side wall of the lower pressing frame 11. The restriction of the lower pressing frame 11 is used to limit the bending amplitude of the multiple protruding blocks 3. At the same time, the bending amplitude of the multiple protruding blocks 3 is kept consistent, thereby ensuring the smooth installation of the display screen in the window 2 and ensuring the firmness of the display screen in the window 2.

[0024] When in use, the door shell window to be bent is placed in the groove, the first electric telescopic rod 9 is started, and the lower pressing frame 11 is driven to move downward through the third fixing frame 10 until the lower pressing frame 11 is pressed on the door shell window to be bent, and then the second electric telescopic rod 12 is started, and the push plate 13 is driven to move upward by the second electric telescopic rod 12. The push plate 13 passes through the hole 7, and then pushes up the multiple protruding blocks 3 on the window 2 of the door shell 1 pressed by the lower pressing frame 11, and combined with the restriction of the lower pressing frame 11, the multiple protruding blocks 3 are all bent to the same amplitude at one time.

[0025] Example 2

[0026] In Embodiment 1, when the upwardly moving push plate 13 pushes the plurality of protruding blocks 3 upward for bending, the push plate 13 and the plurality of protruding blocks 3 will be easily scratched due to friction, which is not conducive to the aesthetics of the plurality of protruding blocks 3 after bending, nor is it conducive to extending the service life of the push plate 13, and will increase the pressure on the second electric telescopic rod 12, which is not conducive to extending the service life of the second electric telescopic rod 12. Figure 2 , 5 and 6, as another preferred embodiment of the utility model, the difference from embodiment 1 is that a lubrication mechanism is fixed on the base 4, the lubrication mechanism includes four guide rollers 16, each guide roller 16 is rotatably arranged on the base 4, each guide roller 16 is fitted with a cloth sleeve 17, and the four cloth sleeves 17 are distributed around the push plate 13. The push plate 13 will contact the four cloth sleeves 17 during the upward movement, and the lubricating oil in the four cloth sleeves 17 will be smeared on the push plate 13. With the assistance of the lubricating oil, the friction between the push plate 13 and the multiple protruding blocks 3 can be reduced. At the same time, it will not affect the effect of the multiple protruding blocks 3 being bent. Since the friction force is reduced, the surfaces of the push plate 13 and the multiple protruding blocks 3 are not prone to scratches, which can ensure the beauty of the surfaces of the multiple protruding blocks 3 and help to extend the service life of the push plate 13 and the second electric telescopic rod 12.

[0027] An automatic oiling mechanism is commonly provided on the first fixed frame 5 and the plurality of cloth sleeves 17. The automatic oiling mechanism comprises a lubricating oil storage box 14. The lubricating oil storage box 14 is fixed on the first fixed frame 5 and mounted on the push plate 13. A plurality of oil guide pipes 15 are connected and fixed on the inner side walls around the lubricating oil storage box 14. The plurality of oil guide pipes 15 on the same side of the lubricating oil storage box 14 are in contact with one of the cloth sleeves 17. The push plate 13 will contact with the plurality of cloth sleeves 17 when it moves up or down. Since the plurality of cloth sleeves 17 will rotate with the plurality of guide rollers 16, the contact area between the plurality of oil guide pipes 15 and the plurality of cloth sleeves 17 can be changed during the rotation of the plurality of cloth sleeves 17. Since the cloth sleeves 17 can absorb the lubricating oil in the oil guide pipes 15, the purpose of automatically oiling the plurality of cloth sleeves 17 is achieved.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
