Next, each processing operation of the work by the steel plate processing apparatus 20 is divided into a corrugated sheet forming operation and a frame rivet setting operation, and will be mainly described with reference to FIG. 1 and FIG. (1) Corrugated Sheet Forming Operation The corrugated sheet forming operation is performed by pressing a steel sheet material 91 (work Wa) shown in FIG. 9 (A) to form a corrugated sheet 92 shown in FIG. 9 (B).
(Work Wb) is formed by using the press machine 30 of the steel plate processing apparatus 20.

First, the interval between the roller conveyors 22 and 24 is set in accordance with the shape of the work Wa as the steel sheet material 91, and the transporter 50 is moved to a predetermined original position on the roller conveyor 22 side. The original position is a position where the transfer device 50 waits for a next step after a series of processing steps by the steel sheet processing apparatus 20 is completed.

Next, the work Wa is carried into the transport path on the roller conveyor 22 side, and the work Wa is positioned in the width direction and the work flow direction. That is, the positioning of the workpiece Wa in the width direction is performed by the positioning guide 23 of the roller conveyor 22, and the positioning of the workpiece Wa in the workpiece flowing direction is performed by the stopper 68 of the plate clamp 60 (see FIG. 7). When the positioning is confirmed, the end of the work Wa is gripped by the plate clamp 60, and the setting of the work Wa on the steel plate processing apparatus 20 is completed. The loading of the work Wa is set such that the longitudinal direction of the work Wa is the flow direction of the work.

Subsequently, the operation panel 82 of the control panel 80
After a predetermined control program corresponding to the work Wa is selected, turning on the start switch causes the control unit 83 to control the processing of the transfer device 50 and the press machine 30.
That is, the transfer device 50 gripping the work Wa gradually moves in the flow direction of the work, that is, in the direction of the roller conveyor 24, so that the work Wa is placed in the forming die (the upper die 35 and the lower die 36) of the press machine 30. Be gradually drawn in. on the other hand,
Since the press machine 30 repeats the vertical movement of the slide frame 34 in synchronization with the movement of the work Wa, the press working by the upper mold 35 and the lower mold 36 is performed at predetermined intervals in the work flow direction of the work Wa. Thus, for example, FIG.
The bead portions 92a are formed at predetermined intervals as shown in FIG.

When the formation of the corrugated sheet 92 is completed, the carrier 50 is returned to the original position in order to carry out the work Wb from the carry-in position on the roller conveyor 22 side. Then, when the work Wb is released from the plate clamp 60 of the transfer device 50 and the work Wb is carried out from the roller conveyor 22, a series of press working by the press machine 30 of the steel plate processing device 20, that is, a corrugated sheet forming operation is completed. .

(2) Frame rivet setting operation The frame rivet setting operation is performed by arranging a plurality of corrugated sheets 92 (work pieces Wb) formed by the above-described corrugated sheet forming operation in a rectangular frame member 93 to form a work piece Wc (see FIG. 9 (C)), and caulking rivets 94 to fix the corrugated plates 92 together or between the corrugated plates 92 and the frame member 93, and is performed using the pressing machine 40 of the steel plate processing apparatus 20.

First, the interval between the roller conveyors 22 and 24 is set according to the shape of the work Wc described above.
The transfer device 50 is moved to a predetermined original position on the roller conveyor 22 side. Then, the lower mold 36 of the press machine 30 is
After bolting to the upper mold 35 via the suspender 39,
The slide frame 34 is raised to a predetermined position (FIG. 3
reference). As a result, the work Wc processed by the pressing machine 40 does not come into contact with the lower
1 can be passed.

Next, the work Wc is carried into the transport path on the roller conveyor 22 side, and the work Wc is positioned in the width direction and the work flow direction. That is, the positioning of the workpiece Wc in the width direction is performed by the positioning guide 23 of the roller conveyor 22, and the positioning of the workpiece Wc in the workpiece flowing direction is performed by the lower claws 73 (see FIG. 8) of the frame clamp 70. Then, when these positionings are confirmed, the frame material 93 of the work Wc is gripped by the frame clamp 70, and the setting of the work Wc on the steel plate processing apparatus 20 is completed. The work Wc is set so that the longitudinal direction of the work Wb constituting the work Wc is in the width direction of the work.

Subsequently, the operation panel 82 of the control panel 80
After a predetermined control program corresponding to the work Wc is selected, the processing of the transfer device 50 and the pressing device 40 is controlled by the control unit 83 by turning on the start switch. In other words, the transfer device 50 gripping the work Wc gradually moves in the flow direction of the work, that is, in the direction of the roller conveyor 24, whereby the work Wc is gradually drawn into the movable range of the pressing machine 40. On the other hand, the pressing machine 40
Is moved into the predetermined range, the sliders 44 and 47 are moved in the width direction of the work Wc in accordance with the time when the movement of the transfer device 50 is interrupted, and the drill 45 is moved at predetermined intervals.
And the vertical movement of the riveting machine 46 is repeated. Therefore, rivet holes 92b are drilled at predetermined intervals in the width direction of the work Wc by the drill 45, and the rivets 94 passed through the rivet holes 92b are swaged by the rivet swaging machine 46 (see FIG. 1).

When drilling of the rivet hole 92b and caulking of the rivet 94 by the pressing machine 40 are completed,
In order to carry out the work Wd from the carry-in position on the roller conveyor 22 side, the transporter 50 is returned to the original position. And
When the work Wd is released from the frame clamp 70 of the transfer device 50 and the work Wd is unloaded from the roller conveyor 22,
A series of pressing by the pressing machine 40 of the steel plate processing apparatus 20,
That is, the frame rivet setting operation is completed.

As described above, according to the steel plate processing apparatus 20 of this embodiment, the press machine 30 provided in the middle of the work transfer path moves the upper die 35 up and down on the frame 31 positioned so as to straddle this transfer path. The press 31 is movably supported by the frame 31, and is supported movably in the cross direction of the transport path. The transfer device 50 that transfers the work along the transfer path is commonly used in both the processing by the press 30 and the processing by the press 40. Thereby, since the press working and the press working are performed on the same transport path, the equipment length in the transport path direction can be shortened as compared with the case where the press machine 30 and the press machine 40 are separately configured. Therefore, the equipment cost can be reduced because the transfer device 50 can be shared, and the equipment length in the direction of the transfer path can be reduced, so that the equipment space can be reduced, that is, the space of the equipment can be saved.

Further, according to the steel plate processing apparatus 20 of the present embodiment, while the work Wa, Wb is held by the plate clamp 60 when the press processing is performed by the press machine 30,
The frame clamp 70 not used during the press working is located outside the moving range of the press 30. Further, when the pressing is performed by the pressing machine 40, the work Wc is held by the frame clamp 70, while the plate clamp 60 that is not used during the pressing is located outside the moving range of the pressing machine 40. In this way, the plate clamp 60 or the frame clamp 70, which is not used in that step, does not interfere with the press machine 30 or the press machine 40 in any of the processing by the press machine 30 and the processing by the press machine 40. The transfer device 50 can be efficiently shared and used for the transfer. In this embodiment, after the press working or the riveting work is completed, the work is transferred to the roller conveyor 22 by the transfer means.
Although it has been described that the work is taken out after returning to the side, the work may be taken out at the processing end position, that is, at the roller conveyor 24 side.

According to the first aspect of the present invention, the pressing machine is supported on the frame of the pressing machine provided in the middle of the conveying route of the steel plate so as to be movable in the cross direction of the conveying route, and the processing by the pressing machine and the processing by the pressing machine are performed. In each case, a common transporter is used for transporting the steel sheet. Thereby, since the press working and the press working are performed in the same transport path,
Compared with the case where the press machine and the press machine are separately configured, the equipment length in the transport path direction can be shortened. Therefore, the equipment cost can be reduced because the transfer device can be shared, and the equipment length can be reduced in the direction of the transfer route, so that the equipment space can be reduced, that is, the equipment can be saved in space.

According to the second aspect of the present invention, the steel sheet is held by the first holding means when the pressing is performed by the press machine, while the second holding means not used during the pressing is moved out of the moving range of the press machine. To position. Further, when pressing is performed by the pressing machine, the steel sheet is held by the second holding means, while the first holding means not used during the pressing is located outside the moving range of the pressing machine. Thereby, in any of the processing by the press machine and the processing by the press machine,
Since the first or second holding means not used in the process does not interfere with the press or the press,
It is possible to efficiently share and use a transfer machine for transferring a steel sheet. Therefore, because the transfer machine can be shared efficiently,
Since the equipment cost can be further reduced and the equipment length in the transport path direction can be shortened, there is an effect that the space of the equipment can be saved.

According to the third aspect of the present invention, since the steel plate processed by the pressing machine is connected to each other by the rivet joint, the plurality of pressed steel plates are arranged and sequentially connected by the rivet joint. Can be applied in case. Thereby, it can be used suitably when performing a series of plastic working to a steel plate, such as arranging a plurality of pressed steel plates and joining them with a rivet joint. Therefore, even when such a series of plastic working is performed on a steel plate, there is an effect that the equipment cost can be reduced and the space of the equipment can be saved.
