When it is necessary to perform many +IIJ bending processes on a metal plate workpiece, such as when forming a reflector plate for lighting equipment, conventionally, when automating this process, the number of bending processes required is In addition to installing processing machines and distributing each bending process to each bending machine, workpieces were transferred between bending machines and equipment was installed to supply and retrieve workpieces to each bending machine. . Automation through line formation is highly effective when the target products are small in number and require the same number of bending processes. However, for products that require different numbers of bending processes, there may be an excess or deficiency in the number of bending machines on the line, making it inefficient to bend a wide variety of products. The current situation is that the government is relying on

Therefore, the present invention comprises a bending machine that can automatically change upper and lower molds into multiple types, a handling device that handles the workpiece, and a support device that holds the workpiece before and after bending. The support device is characterized by being capable of multi-axis control. The present invention will be described in detail below based on the illustrated embodiment. This automation device includes an NC (numerically controlled) die bending machine 1 that can automatically exchange an upper die 16 and a lower die 15 into a plurality of types. a support device 2, a pair of handling devices 3,
It is constructed by installing 3. In the bending process PIil shown here, as shown in FIGS. An upper mold 16 is attached to 12. As is clear from FIG. 3, the lower mold 15 has a square cross section, and has V-bending lower molds 15a and 1 at each corner.
5b, 15d and a reverse bending lower mold 15c are formed, and by rotation thereof, the lower mold 15a to be used is
~15d can be switched. As the upper mold 16, here, ■upper molds 16a and 16c for bending are used.
and 3 of the upper die 16b for inverted V bending! is selectively set in the ram 12. In the figure, 14 is a backage. Support equipment installed on the operator side of the bending machine 1! 12 and the pair of handling devices 3.3 will now be described. The positions and movements of these devices 2, 3.3 are also controlled by numerical control, and the support device 2 installed at the center of the front of the bending film is The three pieces are numerically controlled axes, and the rotation around the Z axis (l) is also numerically controlled, and the support unit 21 has a magnetic workpiece holder 20 rotatably provided at its tip. Handling devices 3 are installed on both sides of the front of the bending machine 1.
, 3 are each equipped with three sleeves of X, Y, and Z, and the rotation around Yil[l (θ) is numerically controlled, and each is equipped with a handling chuck 30 for gripping the workpiece 5. As shown in FIGS. 4 and 5, this handling chuck 30 grips a workpiece 5 with an upper jaw 31 and a lower jaw 32, but the lower jaw 32 is longer than the upper jaw 31. Next, the operation will be explained. Left and right handling device 3
.. The workpiece 5 held at both ends by the handling chucks 30 and 30 of No. 3 is set on the lower mold 15 and the support unit 21, and then the workpiece 5 is abutted against the backage 14, and then the upper mold 16 is lowered. The workpiece 5 is temporarily held between the upper mold 16 and the lower mold 15 by lowering the workpiece 5 until the distance between the mold 15 and the workpiece 5 becomes 7 mm thick. Then, after releasing the handling chuck 30, the upper mold 1G
By lowering it again, bending is performed. During this bending process, the support unit 21 and the handling chuck 30 are made to follow the workpiece 5, and when the bending process is completed, the magnetic workpiece holding section 20 of the support unit 21 is activated to hold the workpiece 5. After the workpiece 5 is chucked again using the left and right handling chucks 30 and 30, and the upper die 16 is raised,
Handling for the next bending process is performed by the handling device 3゜3''c1 or the support device 2. During this time, in the bending machine 1, the upper die 16 and the lower die 15 for the next bending process are The above operation is repeated until the entire bending process is completed. The upper jaw 31 of the handling chuck 30 is made shorter than the lower jaw 32 during the above-mentioned tracking, that is, the handling chuck 30 When the lower claw 32 moves following the workpiece 5, the fifth
As shown in Figure (a), the handling chuck 30 is
Once moved in the axial direction, the end of the workpiece 5 and the upper claw 31
This is to prevent interference with the When Chuck! @5 Both claws 3 in the position shown in Figure (b)
1. Place 32 and chuck workpiece 5. Figure 6 shows three types of upper molds 16a-16c and a 4Mi lower mold 1.
An example of the bending process performed by 5a to 15d is shown. In the opening between the opening and C and the opening between C and 2 in the figure, a small reversal is performed in which the work 5 is rotated around Y Tsumugi (θ). The reason why the upper mold 16b and the lower mold 15c for reverse bending are provided is to avoid the need for a large reversal of rotating the workpiece 5 around the Z-pongee (α). However, since a large reversal may be required depending on the product, the support device 2 is provided with this function as described above. When using the rotary lower mold 15, the lower mold 1 is attached to each corner.
5a to 15d are provided to reduce interference with the embossing process near the bending position of the warp 25, and at the same time, by providing the tapered portion 18 on the holder 11, the lower mold 15 is rotated and set. This is because centering is ensured.

As described above, in the present invention, for a bending machine that can automatically change the upper mold and lower mold into multiple types, the workpiece is handled by a handling device capable of multi-axis control, and the workpiece is also handled by a handling device capable of multi-axis control. Because the support device holds the workpiece before and after bending, it is possible to perform multiple bending processes independently and sequentially, and for this reason, it is difficult to change the content of the bending process or change the number of bending processes. It is flexible and highly efficient in high-mix, low-volume production. Not only does unmanned production reduce production time, but equipment costs are also lower than line automation.
