Description

Ultrasonic Cutting Device for Center Panel of Door Trim of Vehicle

The present invention relates to a cutting device for cutting a center panel of a door trim of a vehicle, and more particularly, to a cutting device using a knife vibrating with ultrasonic waves.

The center panel of the door trim, which is mounted inside the vehicle door, must be cut after molding. In the past, it was generally cut by a waterjet device or a press device. The waterjet method is a method in which a robot is cut by mounting a high-pressure water injector, and the work speed is slow, there is a high possibility of damage to the base metal, and a safety cover is required as a safety problem. The press method is a method of cutting a product with a blade or a mold by placing a base material to be cut on the die and applying pressure from the upper part, but there is a problem of changing the press mold itself when the product is changed quickly, There was a problem that safety measures were required because it was low.

The present invention aims to provide a cutting device that solves the problems of the prior art and has a high work speed, low possibility of product damage, high stability, and low additional cost in product change.

The cutting device for cutting the center panel of the door trim according to the present invention includes a base 10, a support 20 fixed to the base 10, and a rotatably mounted relative to the support 20. A first arm including a first rotating part 30, a sliding part 40 sliding with respect to the first rotating part 30, and a second rotating part rotatably mounted on an end side of the sliding part 40 ( A second arm including a third rotating part 90 rotatably mounted about a longitudinal axis of the second rotating part 50 at an end side of the second rotating part 50;

And a third arm rotatably mounted at an end of the third rotating part 90 and provided with a cutting knife at an end thereof, and an ultrasonic vibration generator 200 for ultrasonically vibrating the cutting knife.

According to the present invention, there is provided a door trim center panel cutting device having a high working speed, low probability of product damage, high stability, and low additional cost of product change.

1 is a perspective view of a cutting device according to the present invention.
Figure 2 is a perspective view after the center panel base material is cut.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

1 shows a perspective view of a cutting device 1 according to the invention. As shown in FIG. 1, the cutting device 1 according to the present invention includes a base 10, a support 20 fixed to the base 10, a first arm, a second arm, And a third arm and an ultrasonic vibration generator 200.

The 1st arm includes the 1st rotation part 30 rotatably mounted with respect to the support part 20, and the sliding part 40 which slides with respect to the rotation part 30. As shown in FIG. The second arm is rotatable about the longitudinal axis of the second rotating part 50 and the second rotating part 50 which is rotatably mounted on the end side of the sliding part 40 and the end of the second rotating part 50. It includes a third rotary unit 90 is mounted. The third arm is rotatably mounted at the end of the third rotating part 90 and is provided with a cutting knife 60 at the end. The ultrasonic vibration generator 200 functions to ultrasonically vibrate the cutting knife.

The die 150 is placed on an upper portion of the base 10, and a jig 160 is disposed on the center panel base 100 of the door trim. The upper side of the jig 160 is provided with jig parts 110 and 130 complementary to the shape of the center panel.

The first rotation part 30 is rotatably mounted about the support shaft 20 about the rotation shaft 25. And the sliding part 40 is inserted into the inside of the first rotating part 30 is provided with a slidable perturbation part 80. The perturbation part 80 may be fixed to the first rotating part 30 side and the perturbation part 80 may be provided inside the sliding part 40 to slide the sliding part 40 itself.

The second rotating part 50 is provided rotatably on the end side of the sliding part 40. In addition, an end portion of the second rotation part 50 is provided with a third rotation part 90 rotatably mounted about a longitudinal axis of the second rotation part 50. Since the 3rd rotating part 90 is provided rotatably about the longitudinal axis of the 2nd rotating part 50, when the cutting knife 60 cut | disconnects the center panel base material 100, it becomes possible to cut | disconnect to the side.

The cutting knife 60 cuts the center panel 100 while performing ultrasonic vibration by the ultrasonic vibration generator 200. A perspective view of the cutting knife 60 after ultrasonic vibration and cutting the center panel base material 100 is shown in FIG. 2. As described above, since the third rotating unit 90 rotates about the longitudinal axis of the second rotating unit 50, the third rotating unit 90 may also cut at the side when cutting the base material 100.

Although the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, the scope of the present invention is determined by the claims below and should not be construed as limited to the embodiments and / or drawings described above. And it should be clearly understood that improvements, modifications and / or modifications apparent to those skilled in the art of the invention described in the claims are included in the scope of the present invention.
