BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite processing machine capable of punching, V-grooving and bending plate materials.

[0002]

2. Description of the Related Art Conventionally, in order to form a flat plate material into a box-shaped product, first, punching is performed on the flat plate material by a punch press to develop the flat plate material into a box-shaped product. It is formed into the shape of the state. Next, a V-shaped groove is machined on the bent portion of the plate material by the V-shaped groove machine. Then, the plate material is bent from the bent portion by a bending machine to form a flat plate material into a box-shaped product. The V-shaped groove is formed in the bent portion of the plate material in order to minimize the radius of curvature of the bent portion when the plate material is bent from the bent portion.

[0003]

However, the processing form of the plate material (punching, V-shaped groove, bending)
Each time, the plate material needs to be carried into a machine corresponding to the processing form, and there is a problem that the work becomes complicated.
In particular, when a large number of plate materials are formed in a box shape, the above problem becomes more remarkable.

[0004]

In order to solve the above-mentioned conventional problems, in the present invention, a punching device for punching a plate material to form the plate material into a desired shape, and a plate material A combination of a groove processing device for processing a V-shaped groove in the bent part and a bending device for processing the V groove in the bent part of the plate material and then bending the plate material from the bent part. It is characterized by

[0005]

In the above structure, in order to form a flat plate material into a box-shaped product, after the plate material is carried into the multi-tasking machine, first the punching device is appropriately operated to punch the plate material. Then, the plate material is formed into a desired shape (a shape in which a box-shaped product is developed). Next, the groove forming device is appropriately operated to form a V-shaped groove on the bent portion of the plate material. Then, the plate material can be bent from the bending portion by appropriately operating the bending device. As a result, a flat plate material can be formed into a box shape. It should be noted that a V-shaped groove may be formed in the bent portion of the plate material before forming the plate material into a desired shape.

Further, when the plate material W is bent downward from the bent portion, as shown in FIG. 5, a predetermined suitable number of upper split bending dies 121 corresponding to the length of the bent portion are used. It is lowered by the operation of a number of folding cylinders 127.

The operation of this embodiment will be described based on the above-mentioned configuration.

A flat plate material W as shown in FIG.
In order to form a box-shaped product WA as shown in FIG. 1, first, after the plate material W is carried into the multi-tasking machine 1, the clamp device 17 holding the plate material W is moved and positioned in the front-rear direction and the left-right direction, and punched. The processing device 21 is appropriately operated as described above to perform punching on the plate material W,
The plate material W is formed into a desired shape (shape in which a box-shaped product WA is developed).

Next, the upper and lower groove processing stations 5
After positioning 5, 5 in the vertical lower position of the striker 53, the groove processing device 33 is appropriately operated as described above to press the plate material W with the plate retainer 63, and the V groove bite by an amount corresponding to the cutting amount. Lower 75. Then, for example, by moving the clamp device 17 holding the plate material W in the rearward direction, a V-shaped groove is formed in the bent portion of the plate material W (in this case, the bent portion extending in the front-rear direction). You can

After the V-shaped groove is formed in the bent portion of the plate material W, the clamp device 17 holding the plate material W is appropriately moved and positioned to a predetermined position of the bending device 35 and bent as described above. The plate material W can be bent from the bent portion by appropriately operating the processing device 35.

With the above operation, the flat plate material W can be formed into the box-shaped product WA. When the plate material W needs to be rotated during the above operation, the center of rotation of the plate material W is positioned between the work support member 93 and the plate retainer 63, and the plate material is collaborated by the work support member 93 and the plate retainer 63. Under the state where W is pressed and grasped, the rotating device is appropriately operated to operate the work pressing member 93 and the plate pressing 63.
Is to rotate.

According to the present embodiment as described above, the plate material W is once loaded into the multi-tasking machine 1 and then the punching machine 31, the groove machine 33, and the bending machine 35 are appropriately operated to obtain a flat plate. Since a plate-shaped plate material W can be formed into a box-shaped product WA, each time the processing form changes,
It is not necessary to carry in the plate material W, and the working efficiency is improved.

The present invention is not limited to the above description of the embodiments, but can be implemented in various other modes by making appropriate changes.

[0029]

As will be understood from the above description of the embodiments, according to the present invention, the punching device, the groove processing device, and the bending device are appropriately installed after the plate material is once loaded into the multi-tasking machine. Since the flat plate material can be formed into a box-shaped product by performing the above operation, it is not necessary to carry in the plate material every time the processing form is changed, and the working efficiency is improved.
