The figure which shows the cross section of the part shape | molded by the left correction unit.

First, the vehicle component 10 is processed into a two-dimensional structure by a roller bending machine or the like, and then the two-dimensional vehicle component 10 is mounted in the torsion processing apparatus 1.

That is, the vehicle component 10 is mounted on the fixed portion 40 installed in the left calibration unit 4, the right calibration unit 6, and the intermediate calibration unit 8 of the torsion processing apparatus 1, and the vehicle component 10. One end of the part 10 is joined to the positioning part 12 to adjust the machining position of the part, and the left part, the right part and the middle part of the vehicle part 10 are fixed by the fixing part 40, respectively.

At this time, the fixing part 40 is the clamping member 44 when the vehicle component 10 is inserted between the clamping member 44 and the fixing block 46 and then seated and fixed on the upper surface of the seating member 45. The second hydraulic cylinder 42 is moved toward the fixing block 46 to fix the vehicle component 10 between the clamping member 44 and the fixing block 46.

As described above, when the left part, the right part, and the middle part of the vehicle component 10 are fixed by the fixing part 40 of the left and right calibration unit 4, the right calibration unit 6, and the intermediate calibration unit 8, the left side The rotary part 20 of the calibration unit 4 is rotated clockwise so that the left side of the vehicle component 10 is twisted clockwise, and the rotary part 20 of the right calibration unit 6 is rotated counterclockwise. As a result, the right side of the vehicle component 10 is twisted in the counterclockwise direction, and the intermediate portion of the vehicle component 10 is maintained without being rotated by the intermediate calibration unit 8.

That is, the left calibration unit 4 and the right calibration unit 6 are mounted to the mounting plate 22 in which the fixing part 40 is installed by the first hydraulic cylinder 30 in the clockwise and counterclockwise directions, respectively. The guide protrusion 25 of the mounting plate 22 is rotated along the guide groove 23 formed on the side surface of the mounting bracket 24, and the first piston rod 31 of the first hydraulic cylinder 30 is rotated. Since the pinion gear 34 is rotated by the rack rod 32 which moves together with the rotary rod 36, the rotation angle of the rotating unit 20 can be measured by the rotary encoder 36.

Therefore, the vehicle component 10 of the two-dimensional structure is processed and molded into a three-dimensional structure while the left side and the right side are twisted by a predetermined angle in the opposite direction by the torsion processing apparatus 1.

For example, in the case of the pillar door frame of the vehicle component 10, the right side of the vehicle component 10 is narrowed to 105 degrees by the right correction unit 6 as shown in FIG. 7. As shown in FIG. 8, the intermediate part of the vehicle part 10 is not changed by the intermediate calibration unit 8 with the separation angle of the part 123 degrees, and as shown in FIG. 9, the vehicle part ( The left side of 10) is machined by the right calibration unit 6 so as to widen the separation angle of the parts to 134 degrees.

As described above, in the torsion processing apparatus 1, the vehicle component 10 is twisted at various angles by adjusting an angle of rotating the rotating unit 20 of the left and right calibration units 4 and 6. .

In addition, since the vehicle parts 10 of various sizes and shapes can be fixed to the fixing part 40, the vehicle parts 10 can be used regardless of the vehicle type.

As described above, the torsion processing apparatus for a vehicle component according to the present invention has been described with reference to the illustrated drawings. Of course, variations may be possible.

Since it is directly twisted by the unit, the right calibration unit, and the intermediate calibration unit to be processed into a three-dimensional structure, there is an advantage that the vehicle parts are processed into a three-dimensional structure in a single device, thereby reducing the number of processing devices and the number of processing steps.

In addition, since the torsion processing is performed at various angles while vehicle parts of various sizes and shapes are fixed to the left calibration unit, the right calibration unit, and the intermediate calibration unit, common use is realized for various vehicles, thereby reducing the installation cost. There is an advantage.

In addition, since the torsion processing apparatus of the present invention is processed into a three-dimensional structure by directly twisting a two-dimensional vehicle parts, the torsion processing apparatus is not only excellent in processing accuracy compared to the three-dimensional processing with a roller as in the prior art, but also the processing generated during long time use There is an advantage that the error is reduced.
