Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] Please see Figure 1-4 The present invention provides the following technical solution: a car bumper bending device, including a housing 1, a drive mechanism 3 is provided on one side of the housing 1, a connecting seat 4 is provided at one end of the drive mechanism 3, a bending pressure roller 6 is provided on the side wall of the connecting seat 4, a conveying mechanism 5 is provided on the side wall of the housing 1 and below the bending pressure roller 6, a fixed placement component 2 is provided on the side wall of the housing 1, and an installation component 7 is provided between the connecting seat 4 and the bending pressure roller 6.

[0022] Specifically, the mounting assembly 7 also includes a storage component 71, a mounting plate 72, a mounting groove 73, an arc-shaped groove 74, a clamping block 75, a fixing screw 76, an external threaded cylinder 77, and a mounting disc 78. The mounting plate 72 is fixedly connected to the side wall of the connecting seat 4. The mounting plate 72 has a mounting groove 73 inside. The end of the bending roller 6 near the mounting groove 73 is fixedly connected to the mounting disc 78. The side wall of the mounting groove 73 has an arc-shaped groove 74. The fixing screw 76 is fixedly connected inside the arc-shaped groove 74. A clamping block 75 is located inside the arc-shaped groove 74 and above the mounting disc 78. A round hole is opened on the clamping block 75 at the position corresponding to the fixing screw 76. An external threaded cylinder 77 is threadedly connected to the outer side wall of the fixing screw 76 and above the clamping block 75. The storage component 71 is located on the side wall of the housing 1.

[0023] By adopting the above technical solution, according to the bending curvature of the car bumper to be processed, a bending component of appropriate size is taken out from the storage part 71 and inserted into the mounting groove 73 on the mounting plate 72. The mounting plate 78 moves to fit against the inner side wall of the mounting groove 73. Then, the clamping block 75 is placed into the arc groove 74, and the fixing screw 76 passes through the round hole through the clamping block 75. Then, the external threaded cylinder 77 is rotated and screwed onto the fixing screw 76 and made to fit against the clamping block 75. The clamping block 75 can be used to clamp and fix the mounting plate 78, which facilitates the disassembly and assembly of the bending component and the connecting seat 4. This also facilitates the replacement of bending components of different diameters. Bending components of different diameters can be used to perform bending operations of different curvatures on the car bumper.

[0024] Specifically, the storage component 71 includes a placement frame 711, a movable base plate 712, spare bending rollers 713, an opening 714, and side rods 715. The placement frame 711 is fixedly connected to the side wall of the housing 1. The movable base plate 712 is slidably connected inside the placement frame 711. The side rods 715 are fixedly connected to the side wall of the movable base plate 712. An opening 714 is provided on the placement frame 711 at the position corresponding to the side rods 715. Several spare bending rollers 713 are arranged above the movable base plate 712.

[0025] By adopting the above technical solution, when it is necessary to take out bending parts of different diameters, the side rod 715 is moved along the opening 714. The movement of the side rod 715 drives the movement of the moving base plate 712. The movement of the moving base plate 712 drives the spare bending pressure roller 713 to move out of the placement frame 711. Then, the spare bending pressure roller 713 of the appropriate diameter is taken out from the inside of the placement frame 711 for use, which facilitates the storage and placement of the spare bending pressure roller 713 and the bending pressure roller 6.

[0026] Specifically, a guide slider is fixedly connected to the end of the movable base plate 712 away from the side rod 715, and a guide groove is provided on the inner side wall of the placement frame 711 at the position corresponding to the guide slider.

[0027] By adopting the above technical solution, the moving base plate 712 moves and drives the guide slider to move inside the guide groove. With the cooperation of the guide slider and the guide groove, the movement of the moving base plate 712 can be guided, thereby improving the stability of the movement of the moving base plate 712.

[0028] In this embodiment, the operator moves the side rod 715 along the opening 714. The movement of the side rod 715 causes the moving base plate 712 to move, which in turn causes the spare bending roller 713 and bending roller 6 to move and protrude from the placement frame 711. Then, a spare bending roller 713 or bending roller 6 of suitable diameter is taken out from inside the placement frame 711. The spare bending roller 713 or bending roller 6 is then inserted into the mounting groove 73 on the mounting plate 72. The mounting plate 78 moves accordingly to fit against the inner wall of the mounting groove 73. Then, the clamping block 75 is placed inside the arc-shaped groove 74, and the fixing screw 76 passes through the round hole. The clamping block 75 is used to tighten and fix the external threaded cylinder 77 onto the fixing screw 76, and make it fit against the clamping block 75. The clamping block 75 can be used to clamp and fix the mounting plate 78, which facilitates the disassembly and assembly of the bending component and the connecting seat 4, and facilitates the replacement of bending components of different diameters. Bending components of different diameters can be used to bend the car bumper with different curvatures. Then, the conveying mechanism 5 is used to move the car bumper to below the spare bending roller 713 or bending roller 6. Then, the driving mechanism 3 is used to move the spare bending roller 713 or bending roller 6 down to bend the car bumper.

[0029] Example 2

[0030] The difference between this embodiment and embodiment 1 is that the fixed placement assembly 2 includes a side plate 21 and a retaining rod 22. The side plate 21 is fixedly connected to the side wall of the chassis 1, and the retaining rod 22 is provided above the side plate 21. A rubber pad is fixedly connected to one end of the retaining rod 22.

[0031] Specifically, the fixed placement component 2 also includes a base block 23, a connecting rod 24, a connecting spring 25, a U-shaped frame 26, and a connecting groove 27. The end of the clamping rod 22 near the side plate 21 is fixedly connected to the base block 23. A connecting groove 27 is provided inside the side plate 21 at the position corresponding to the base block 23. The connecting rod 24 is fixedly connected to the side wall of the base block 23. A U-shaped frame 26 is fixedly connected to the side wall of the side plate 21 around the connecting rod 24. A connecting spring 25 is fixedly connected between the connecting rod 24 and the U-shaped frame 26.

[0032] By adopting the above technical solution, after the bent car bumper is placed on the side plate 21, the clamping rod 22 moves under the squeezing action of the car bumper. The movement of the clamping rod 22 causes the bottom block 23 to move inside the connecting groove 27. The movement of the bottom block 23 causes the connecting rod 24 to move inside the U-shaped frame 26. The movement of the connecting rod 24 squeezes the connecting spring 25, ensuring the clamping effect of the clamping rod 22 on the car bumper.

[0033] In this embodiment, after the car bumper is bent, it is removed from the conveying mechanism 5 and placed on the side plate 21. The clamping rod 22 moves under the pressure of the car bumper. The movement of the clamping rod 22 causes the bottom block 23 to move inside the connecting groove 27. The movement of the bottom block 23 causes the connecting rod 24 to move inside the U-shaped frame 26. The movement of the connecting rod 24 compresses the connecting spring 25, ensuring the clamping effect of the clamping rod 22 on the car bumper. This ensures the stability of the car bumper and prevents friction between the car bumper and objects in the surrounding environment, thus avoiding scratches on the car bumper, ensuring the aesthetics of the car bumper surface, and improving the performance of the car bumper.

[0034] The structure and principle of the drive mechanism 3, which consists of a movable groove, a connecting slide, a spring telescopic strut, a connecting support, a hydraulic cylinder, and a hydraulic rod, have been disclosed in a bending device for processing car bumpers in Chinese patent application number 202420498769.X. Its working principle is as follows: A movable groove is provided on the side wall of the housing 1, and a connecting slide is correspondingly provided on both sides of the movable groove. A spring telescopic strut is connected to the inner bottom wall of the movable groove. A connecting seat 4 is slidably connected inside the movable groove. A connecting support is fixedly connected to the top of the housing 1, and a hydraulic cylinder is connected to the top of the connecting support. A hydraulic rod is connected to the output end of the hydraulic cylinder, and the end of the hydraulic rod away from the hydraulic cylinder is fixedly connected to the connecting seat 4. In use, the hydraulic cylinder is started, which drives the hydraulic rod to move downward. The downward movement of the hydraulic rod drives the connecting seat 4 to move downward, and the downward movement of the connecting seat 4 drives the bending roller 6 to move downward to perform a bending operation on the car bumper.

[0035] The structure and principle of the conveying mechanism 5, composed of a first conveying roller, a second conveying roller, a first drive shaft, rollers, a belt, a drive motor, a second drive shaft, a connecting roller, a fixed support plate, a connecting spring, a movable shell plate, and a rotating roller, have been disclosed in a bending device for processing automobile bumpers in Chinese patent application number 202420498769.X. Its working principle is as follows: A drive motor is fixedly connected to the inner wall of the housing 1. Two rollers are connected to the output end of the drive motor. A belt is fitted onto the outer wall of each roller. A second drive shaft is connected to the side of the roller furthest from the drive motor. A second conveying roller is connected to the second drive shaft. Through the action of the belt and another roller, the side of the roller furthest from the drive motor is connected to the first drive shaft. A connecting roller is connected to the first drive shaft. The first conveyor roller is connected to the side wall of the housing 1 at equal intervals. A fixed support plate is fixedly connected to the side wall of the housing 1 above the connecting roller. A connecting spring is connected to the bottom of the fixed support plate. A movable shell plate is connected to the end of the connecting spring away from the fixed support plate. A rotating roller is rotatably connected to the bottom inner side of the movable shell plate. In use, the bumper to be bent is placed on the connecting roller, and the bottom wall of one end of the bumper contacts the outer wall of the first conveyor roller. Then, the drive motor drives the roller to drive the first drive shaft and the first conveyor roller on it to rotate. Through the action of the shaft belt and another roller, the second drive shaft and the second conveyor roller on it are driven to rotate to convey the bumper that is in contact with the outer wall of the first conveyor roller. The bumper is then sandwiched between the first conveyor roller and the second conveyor roller.

[0036] The working principle and usage process of this utility model are as follows: The operator moves the side rod 715 along the opening 714. The movement of the side rod 715 drives the movement of the moving base plate 712. The movement of the moving base plate 712 drives the spare bending roller 713 and bending roller 6 to move out of the placement frame 711. Then, a spare bending roller 713 or bending roller 6 of appropriate diameter is taken out from inside the placement frame 711. Finally, the spare bending roller 713 or bending roller 6 is inserted into the mounting groove 73 on the mounting plate 72. The mounting plate 78 moves to fit against the inner wall of the mounting groove 73, and then the clamping block 75 is placed inside the arc-shaped groove 74. The fixing screw 76 passes through the round hole and through the clamping block 75. Then, the external threaded cylinder 77 is rotated and screwed onto the fixing screw 76, making it fit against the clamping block 75. The clamping block 75 can be used to clamp and fix the mounting plate 78, which facilitates the disassembly and assembly of the bending component and the connecting seat 4, and facilitates the replacement of bending components of different diameters. The bending components of different diameters can be used to... The car bumper undergoes bending operations at different curvatures. Then, the conveying mechanism 5 moves the car bumper to below the spare bending roller 713 or bending roller 6. Next, the driving mechanism 3 moves the spare bending roller 713 or bending roller 6 downwards to perform the bending operation. After bending, the car bumper is removed from the conveying mechanism 5 and placed on the side panel 21. The clamping rod 22 moves under the pressure of the car bumper. This movement of the clamping rod 22 causes the bottom block 23 to move inside the connecting groove 27. The movement of the bottom block 23 causes the connecting rod 24 to move inside the U-shaped frame 26. The moving connecting rod 24 presses against the connecting spring 25, ensuring the clamping effect of the clamping rod 22 on the car bumper. This ensures the stability of the car bumper, prevents friction between the car bumper and objects in the surrounding environment, avoids scratches on the car bumper, maintains the aesthetic appearance of the car bumper surface, and improves the overall performance of the car bumper.
