Conventional technology Conventionally, for panel-shaped workpieces that require different types of processing such as cutting, bending, drilling, seat formation, and hemming, such as the inner side panel inside a truck loading platform, each processing is performed separately. Because the work was done individually on each machine, it took a lot of time and equipment to attach and remove the workpiece to and from each machine, and to transport the workpiece between each machine.Also, since the processing content differs depending on the car model, The press molds and jigs are different for each type of press, and not only are these production costs expensive, but they also require space and transportation work to place them within the factory.
This resulted in an increase in storage space for pressed products and an increase in transportation costs.

Purpose The present invention has been made in order to eliminate the drawbacks of the above-mentioned prior art, and its purpose is to cut, bend, punch holes, and form seats on a panel-shaped work in a single process. By providing multiple press heads, a hemming mechanism, and a workpiece conveyance device so that they can be completed at the same time, it is possible to eliminate the need to separate presses using separate press machines, and to process panels with a single machine. The purpose of the present invention is to enable various types of processing to be performed on shaped workpieces, and thereby eliminate the need for equipment for transporting workpieces between machines and the number of man-hours required for transporting the workpieces. Another purpose is to enable one machine to handle panel-shaped workpieces with different specifications, to significantly reduce the number of pressed products and the storage space required, and to facilitate the management and transportation of pressed products. The aim is to reduce losses on work in progress.

It is also possible to provide a device configured to be able to perform cutting and bending of complex shapes including.

The hemming mechanism 4 is connected to an initial workpiece 5 in which a flange 5f is bent in a direction perpendicular to the paper surface on the entire circumference as shown in FIG. It has a rotary punch 20 for processing a hemming 5i on a flange 5f,
As shown in FIGS. 1 and 10, the rotary punch 20 is provided over the entire width of the press processing apparatus 1, and is rotated by at least 90 degrees by a rotating shaft 22 rotatably supported on a base 21. By rotating as shown by arrow F in FIG. 10, the flange 5f of the panel-shaped workpiece 5 can be hemmed.

In the press working apparatus 1 according to the present invention, the conveying device 3, the plurality of press working heads 2A, 2B, and 2C, and the hemming mechanism 4 are constructed as one machine.

Function In the press working apparatus 1 according to the present invention, a large panel workpiece 5 having a flange 5f formed on the entire circumference as shown in FIG. This machine is designed to perform various types of processing on four types of panel-shaped workpieces 5. For example, the panel-shaped workpiece 5 shown in FIG. When processing, the panel-shaped workpiece 5 is temporarily held by the workpiece holder 9,
It is conveyed upward by the conveyor belt 6 of the conveyor 3 and delivered to the internal conveyor, and the rotary punch 20 is operated to process the hemming 5i of the upper flange 5f in the figure.

Next, for a panel-shaped workpiece 5 as shown in FIG. 4, that is, a side panel used for a long body of a two-wheel drive vehicle, only the press working head 2B is operated to cut the concave portion G corresponding to the tire house and form the flange. 5f bending is performed, but since the depth of the recess G is deeper than that of a four-wheel drive vehicle, the recess G is cut and bent as deep as the portion B shown in Figure 4, and Similarly, a hemming 5i is formed on the upper flange 5f in the figure.

Next, in machining the panel-shaped workpiece 5 shown in FIG.
Since the hatched parts A and C are cut instead of being formed shallowly as shown in the figure, the press working heads 2A and 2C are activated.
Cutting these and bending the flange 5f are performed simultaneously, and then the upper flange 5f in the figure
Processing of hemming 5i of f is performed.

Next, a panel-shaped workpiece 5 as shown in FIG.
That is, when processing the workpiece 5 as a side panel inner for a short body of a two-wheel drive vehicle, the hatched portions A and C are cut, and the recess G is formed to be as deep as the hatched portion B. All press working heads 2A,
2B and 2C are operated, and cutting, bending of the flange 5f, processing of the hole 5g, and formation of the seat 14h are performed simultaneously.

In addition, in the above-mentioned processing step, the press processing head 2C has a punch 1 as shown in FIG.
2 and the recesses 14g and 14h of the die 14 to form a hole 5g and a seat 5h in the workpiece 5, and the punch 13 and the recess 14f of the die 14 to bend the flange 5f. Further, as the rotary punch 20 rotates as shown by arrow F in FIG. 10, the upper flange 5f in the figure
Hemming processing is applied to each.

Further, the cutting and bending of the flange 5f will be explained with reference to FIGS. 8 and 9. After the punch 10 is lowered to cut the workpiece 5 at its tip 10b as shown in FIG. By pressing the cut end of the workpiece 5, the flange 5f can be bent at right angles as shown in FIG.

In addition, when a punch 15 as shown in FIG. 11 is used, cutting and bending of a panel-like workpiece 5 into a complicated shape, mainly relief machining of a flange 5f at a corner part as shown in FIG. 12, can be performed. It is possible to do so. That is, the first punch 15
The relief portion 5a of the flange 5f of the workpiece 5 is cut by the blade portion 15a of the punch 15, and the curved blade portion 1 of the punch 15 is cut.
5b to form a relief portion 5b of the flange 5f of the workpiece 5, and the inclined blade portion 15c of the punch 15 to cut the sloped surface 5c of the flange 5f of the workpiece 5 in the air where no die exists, and further cut the sloped surface 5c of the flange 5f of the workpiece 5 in a straight line. The flange 5f of the workpiece 5 is cut by the shaped blade portion 15d.
Cut the straight part 5d of the punch 15, and cut the slope part 15 of the punch
By e, the flange 5f can be bent at 90 degrees along the bent portion 5e of the flange 5f with a width of l. In this case die 16
and 18 are used, and the cutting of the slope 5c is performed at an angle α, and this part is cut in the air without the presence of a die. However, as a result of the test, it was possible to cut with a sufficiently clean cut. has been proven.

The panel-shaped workpiece 5, on which the hemming process has been completed by the rotary punch 20, is carried out from inside by the conveyor belt 6 of the conveyance device 3 rotating in the opposite direction to the carrying-in of the workpiece, and sent downward. Then, the worker carries out the work to the next process.

According to the press working apparatus 1 of the present invention as described above, the workpiece 5 as shown in FIG.
When manufacturing panel-like workpieces 5 of different shapes, for example, four types as shown in FIGS.
By properly using a plurality of press working heads 2A, 2B, and 2C, it becomes possible to perform these four types of processing with one press working apparatus 1. As a result of the test, according to the present invention, the cost for the press die is approximately 50% of that of the conventional example, and the press processing equipment 1
It has been confirmed that the space required is reduced by approximately 40% compared to the conventional example.

Effects Since the present invention is configured and operates as described above, it is possible to simultaneously complete multiple processes of cutting, bending, drilling, and forming seats on a panel-shaped workpiece in one operation. Since a press processing head, hemming mechanism, workpiece conveyance device, etc. are installed, it is possible to eliminate the need for separate presses using separate press machines, and it is now possible to perform various types of processing on panel-shaped workpieces with one machine. This has the effect of eliminating the need for equipment for transporting workpieces between machines and the number of man-hours for transporting the workpieces. In addition, one machine can handle panel-shaped workpieces with different specifications, making it possible to significantly reduce the number of pressed products and the space required to store them.This also simplifies the management and transportation of pressed products, and allows for more work-in-progress. This has the effect of reducing losses.
