Description

Technical Field

[0001] The utility model relates to the technical field of automobile trim strip processing devices, in particular to an automatic bending device for automobile trim strips. Background Art

[0002] Car trim is a common part on cars, generally divided into aluminum trim and rubber trim. When producing aluminum trim, its shape is first formed, and then it is sawed, stretched and bent according to the installation position on the car and design requirements. The bending operation of aluminum trim is generally performed by larger equipment such as three-dimensional bending machines. For irregular aluminum trim with three-dimensional distortion, this bending effect is better, but for aluminum trim whose bending direction is only on one plane, the processing cost of using a three-dimensional bending machine is higher, resulting in higher cost and time.

DETAILED DESCRIPTION

[0034] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0035] An automatic bending device for automobile trim strips comprises: a fixing member 1 having at least two support blocks 2 arranged side by side on the same side of the fixing member 1, the two support blocks 2 being rotatably arranged on the fixing member 1, and the rotation centers of the two support blocks 2 being located on the side away from each other; a positioning portion 3, the two support blocks 2 being provided with the positioning portion 3, the positioning portion 3 being integrally formed with the support blocks 2 or being separately arranged, the positioning portion 3 extending into the automobile trim strip 22 for positioning the automobile trim strip 22 to be bent; a pressing block 4, which is movably arranged above the fixing member 1, the pressing block 4 having an arc-shaped pressing portion 5 facing one side of the fixing member 1, the arc-shaped pressing portion 5 being used for bending the automobile trim strip 22; the automobile trim strip 22 to be bent can be fixed on the support block 2 because the positioning portion 3 penetrates into it, and the arc-shaped pressing portion 4 presses on it to drive the two support blocks 2 to rotate, thereby performing a bending operation.

[0036] Based on the above embodiments, an exemplary structure of this solution is as follows: Figures 1 to 6 As shown, two support blocks 2 are provided on both sides of the fixing part 1 along the horizontal direction, and there are also two pressing blocks 4, and one pressing block 4 corresponds to two support blocks 2. When working, the positioning part 3 is first inserted into the automobile trim 22 to fix the automobile trim 22, and then the two pressing blocks 4 are moved toward the direction of the fixing part 1. After the pressing block 4 is pressed on the automobile trim 22, the pressure is transmitted to the support block 2, so that the two support blocks 2 on the same side of the fixing part 1 rotate. During the rotation of the support blocks 2, the ends of the two support blocks 2 that are close to each other are farther away from the rotation center, so their rotation path is longer, and the closer the two support blocks 2 are to their respective rotation centers, the shorter their rotation path is. Therefore, under the action of the arc-shaped pressing part 5 of the pressing block 4, the automobile trim 22 gradually becomes curved until the bending operation of the automobile trim 22 is completed.

[0037] In the present solution, the support block 2 is rotatably set on the fixing member 1, and the automobile trim 22 is bent by a pressing block 4 having an arc-shaped pressing portion 5, thereby replacing the traditional three-dimensional bending machine, simplifying the bending operation of the automobile trim 22, and by arranging the pressing block 4 and the support block 2 on both sides of the fixing member 1, the automatic bending device of the present solution can process two automobile trims 22 at the same time, thereby improving the bending efficiency of the automobile trim 22 and reducing the manufacturing cost of the automobile trim 22.

[0038] The fixing member 1 is provided with a spring 6 corresponding one-to-one with the support block 2, and a first limit block 7 corresponding one-to-one with the support block 2. The spring 6 abuts against the lower end surface of the support block 2 away from the rotation center, and the first limit block 7 movably abuts against the upper end surface of the support block 2 away from the rotation center.

[0039] When the pressing block 4 drives the supporting block 2 to rotate by pressing the automobile trim 22, the end of the supporting block 2 away from the rotation center presses on the spring 6, causing the spring 6 to undergo elastic deformation. When the automobile trim 22 is bent and the pressing block 4 is reset, the spring 6 resumes its extended state and pushes the supporting block 2 to rotate toward its initial position (horizontal state). When the supporting block 2 rotates to abut against the first limit block 7, the supporting block 2 is reset.

[0040] The bending device of the present scheme also includes: a frame 8, which is arranged above the fixing member 1; a driving member 9, which is vertically arranged on the frame 8; a moving block 10, which is movably arranged on the frame 8, and the output end of the driving member 9 passes through the frame 8 and is connected to the moving block 10, and is used to drive the moving block 10 to move in the vertical direction; a connecting plate 11, which is arranged on the side of the moving block 10, and the pressing block 4 is connected to the connecting plate 11; a first supporting seat 12, which is arranged on one side of the fixing member 1; a second limiting block 13, which is connected to the first supporting seat 12 and movably abuts against the end of the automobile trim 22.

[0041] The driving member 9 can be a pneumatic cylinder, an oil cylinder or an electric cylinder. The driving member 9 drives the moving block 10 to move through the moving block 10 to realize the movement process of the pressing block 4. The connecting plate 11 is used to connect the pressing block 4 to the moving block 10. The car trim 22 is placed behind the fixing member 1, and its end rests on the second limit block 13, which is used to limit the car trim 22.

[0042] The connecting plate 11 is provided with a plurality of waist-shaped holes 14 , and the pressing block 4 is provided with threaded holes 15 corresponding to the waist-shaped holes 14 one by one. Bolts pass through the waist-shaped holes 14 and are connected to the threaded holes 15 .

[0043] The waist-shaped hole 14 is provided to adjust the height of the arc-shaped pressing portion 5 on the pressing block 4 relative to the moving block 10 , so as to meet the bending requirements of decorative strips with different bending degrees.

[0044] A guide channel 16 is provided on the fixing member 1 , and a guide plate 17 is connected to the side of the moving block 10 facing the fixing member 1 . The guide plate 17 is movably inserted in the guide channel 16 to provide guidance for the movement of the pressing block 4 , thereby ensuring the bending quality of the automobile trim 22 .

[0045] The fixing member 1 includes: a bottom plate 23; two vertical plates 18 vertically arranged on the bottom plate 23, the two vertical plates 18 are arranged at intervals, and the gap between the two vertical plates 18 is used to form a guide channel 16; a second support seat 19, which is connected to the bottom plate 23 and is located on the side of the vertical plate 18, and a rotating shaft 20 passing through the support block 2 is arranged between the vertical plate 18 and the second support seat 19, which is used to realize the rotation connection of the support block 2 on the fixing member 1; a third support seat 21, which is arranged between the vertical plate 18 and the second support seat 19, and one end of the spring 6 is fixed on the third support seat 21.
