DETAILED DESCRIPTION

[0019] 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.

[0020] like Figures 1 to 6 As shown, the automobile trim flanging device comprises an upper template 1 and a lower template 2 which are arranged correspondingly in the upper and lower directions. The lower template 2 is provided with a lower flanging block 3 for placing the trim. The lower template 2 is connected with a connecting plate 4 which is provided with a movable hole 5. The connecting plate 4 is located above the lower flanging block 3. The upper template 1 is movably connected with an upper flanging block 6 which is obliquely and movably inserted in the movable hole 5. When the upper template 1 moves downward, it can drive the upper flanging block 6 to move downward in the movable hole 5.

[0021] The lower template 2 is provided with a lower flange block 3 for placing the decorative strip, and the upper flange block 6 is movably inserted in the movable hole 5 and movably connected with the upper template 1. When the upper template 1 moves downward, it can drive the upper flange block 6 to move downward, and then the lower end of the upper flange block 6 can gradually move toward the direction close to the decorative strip and contact with the decorative strip. When the lower end of the upper flange block 6 contacts with the decorative strip, it can drive the end of the decorative strip to flip downward to achieve the purpose of flanging the decorative strip. Because the upper flange block 6 is arranged in the movable hole 5, the upper flange block 6 is always restricted by the movable hole 5 during the movement. Even if the upper flange block 6 is subjected to the reaction force of the decorative strip, it will not shift in position, thereby ensuring the flanging accuracy.

[0022] An adjusting block 7 is arranged in the movable hole 5 , and the upper flange block 6 is movably inserted in the adjusting block 7 . A first limiting inclined surface 8 is arranged on the adjusting block 7 , and a second limiting inclined surface 9 is arranged on the upper flange block 6 . The second limiting inclined surface 9 movably abuts against the first limiting inclined surface 8 .

[0023] The upper flanging block 6 is movably inserted in the adjusting block 7, and the first limiting slope 8 and the second limiting slope 9 are movably abutted against each other. When the upper flanging block 6 is driven to move downward by the upper template 1, the upper flanging block 6 can only move along the path limited by the first limiting slope 8, that is, when the upper flanging block 6 moves downward, its path has been restricted, and even if the upper flanging block 6 is subjected to forces in other directions except the upper template 1, it will not shift in position, thereby improving the flanging accuracy and flanging quality.

[0024] A first flange slope 10 is provided at the lower end of the upper template, and a second flange slope 11 is provided at the end of the lower template. The first flange slope 10 is located above the second flange slope 11 and the two are parallel to each other. When the upper template moves downward to a preset position, the first flange slope 10 can abut against the second flange slope 11.

[0025] The first flange bevel 10 and the second flange bevel 11 are parallel to each other, so during the downward movement of the first flange bevel 10, it first contacts with the decorative strip and drives the decorative strip to flip, and the first flange bevel 10 gradually moves downward and approaches the second flange bevel 11. When the first flange bevel 10 moves downward to a predetermined distance, the first flange bevel 10 can abut against the upper end surface of the decorative strip, and the second flange bevel 11 can abut against the lower end surface of the decorative strip, that is, the purpose of flanging the decorative strip is completed and the upper flange block 6 is stopped from moving further. In this process, the second flange bevel 11 can abut against the lower end surface of the decorative strip only after the first flange bevel 10 moves to a preset distance (that is, the flanging of the decorative strip is completed), that is, during the flanging process of the decorative strip, the decorative strip is only subjected to the downward force of the first flange bevel 10, and the second flange bevel 11 is not in contact with the lower end surface of the decorative strip. This can prevent the decorative strip from being stretched by the pulling force, thereby improving the flanging accuracy of the decorative strip and avoiding damage to the decorative strip.

[0026] An adjusting piece 12 is provided on the connecting plate 4, and a first adjusting bolt 13 is inserted into the adjusting piece 12. One end of the first adjusting bolt 13 passes through the connecting plate 4 and is threadedly connected to the adjusting block 7. Adjustment holes 14 are opened on the two opposite sides of the connecting plate 4. A second adjusting bolt 15 is movably inserted in each adjusting hole 14, and one end of the second adjusting bolt 15 is threadedly connected to the adjusting block 7.

[0027] The first adjusting bolt 13 is inserted on the adjusting member 12 and passes through the connecting plate 4 to be connected with the adjusting block 7. When gaskets of different thicknesses are sleeved on the first adjusting bolt 13, the front and rear positions of the adjusting block 7 in the moving hole 5 can be changed, which is equivalent to adjusting the front and rear positions of the upper flanging block 6. Similarly, setting gaskets of different thicknesses on the second adjusting bolt 15 can change the left and right positions of the adjusting block 7 in the moving hole 5, thereby realizing flanging of different decorative strips and decorative strips at different angles.

[0028] The upper flanging block 6 is provided with a connecting block 16 , and the connecting block 16 is provided with a downward pressing inclined groove 17 . The downward pressing inclined groove 17 and the upper template 1 are provided with a downward pressing roller 18 , and the downward pressing roller 18 is movably inserted in the downward pressing inclined groove 17 .

[0029] When the upper template 1 moves downward, the lower pressure roller 18 can move in the lower pressure inclined groove 17 and give the upper flange block 6 a downward force, thereby driving the upper flange block 6 to move downward. In the process of the upper template 1 and the upper flange block 6 moving downward, under the action of the lower pressure inclined groove 17, the vertical downward force of the lower pressure roller 18 is converted into a force parallel to the upper flange block 6, thereby preventing the vertical force of the upper flange block 6 from causing excessive friction between the adjusting block 7 during oblique movement, reducing the wear of the lower flange block 3, and the lower pressure roller 18 itself rotates and changes its relative position with the lower pressure inclined groove 17, so that the force of the lower pressure roller 18 on the lower pressure inclined groove 17 is smoother, and there will be no jamming phenomenon, thereby improving the smoothness of the movement of the lower flange block 3.

[0030] A pressing cylinder 19 is provided on the upper template 1, and the lower end of the pressing cylinder 19 is connected to the connecting plate 4. When the pressing cylinder 19 is working, it can drive the pressing roller 18 to move downward or upward.

[0031] A nitrogen spring 20 is provided on the adjusting block 7 and is inserted in the upper flanging block 6. When the upper flanging block 6 moves downward, the nitrogen spring 20 is squeezed to generate a rebound force. When the flanging work is completed, the upper template 1 is driven by the downward pressure cylinder 19 to move upward. At this time, the upper flanging block 6 is no longer subjected to the downward squeezing force. The elastic force of the nitrogen spring 20 itself can drive the upper flanging block 6 to move upward to prepare for the next flanging work.

[0032] A supporting block 21 is disposed at the upper end of the adjusting block 7 , and a supporting surface 22 is disposed on the upper flange block 6 . The lower end surface of the supporting block 21 movably supports the supporting surface 22 .

[0033] When the upper flange block 6 is driven by the nitrogen spring 20 to move upward to a certain distance, the abutment surface 22 can abut against the lower end surface of the abutment block 21, and then stop moving upward, preventing the elastic force of the nitrogen spring 20 from driving the upper flange block 6 to separate from the adjustment block 7.

[0034] Two limiting posts 23 are oppositely arranged on the lower flange block 3, and a placement gap 24 is formed between the two limiting posts 23 to prevent one end of the decorative strip from being located in the placement gap 24 when the decorative strip is on the lower flange block 3, thereby positioning the position of the decorative strip.

[0035] A pressing oil cylinder 25 is provided on the lower mold plate 2, and the upper end of the pressing oil cylinder 25 is connected to the connecting plate 4. The lower end surface of the connecting plate 4 is provided with a pressing groove 26 having the same shape as the lower flange block.

[0036] The pressing cylinder 25 can drive the connecting plate 4 to move downward. At this time, the pressing groove 26 can gradually approach the decorative strip until the pressing groove 26 abuts against the upper end surface of the decorative strip. Because the decorative strip is placed on the lower flange block 3, the decorative strip is clamped under the joint action of the lower flange block 3 and the pressing groove 26 to prevent the decorative strip from shaking during flanging.

[0037] The working process is as follows: the decorative strip is initially positioned horizontally in the placement gap 24, and then the decorative strip falls onto the lower flange block 3. At this time, the pressing cylinder 25 drives the connecting plate 4 to move downward, and then the pressing groove 26 fixes the decorative strip on the lower flange block 3. Then the pressing cylinder 19 works to drive the upper template 1 to move downward, and then the pressing roller 18 can move in the pressing inclined groove 17 and provide downward pressure to the pressing inclined groove 17. After the upper flange block 6 is subjected to the downward pressure, it moves downward in the adjusting block 7, and then the decorative strip is flanged until the lower end face of the decorative strip rests on the second flange inclined surface 11.

[0038] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways without departing from the scope defined by the spirit of the present invention.
