However, in such a long material processing machine, in order to process a long material, a plate material feeding amount corresponding to the length of the long material is required. As a result, it is necessary to increase the length of the entire machine in accordance with the length of the plate material, and the installation space for the machine increases accordingly,
There is a problem that it becomes difficult to maintain the processing accuracy as the product feed amount increases.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and to provide a long material processing machine capable of processing an arbitrary position of a plate material with a plate material feed amount shorter than the length of the long material plate and reducing an installation space. With the goal.

SUMMARY OF THE INVENTION A long material processing machine according to the present invention includes a plate material feeding means for feeding a long material plate material in one direction along a longitudinal direction, and a plate material feeding area provided by the plate material feeding means. First and second processing means installed at predetermined intervals in the one direction. These first and second
Has a tool block for holding a tool, a block moving means for moving the tool block in a direction orthogonal to the one direction, and a tool driving means for driving a tool held by the tool block. . According to this configuration, the first and second processing means can share and process a part of the plate material in the longitudinal direction. for that reason,
The feed amount of the plate material by the plate material feeding means may be shorter than the length of the plate material, and the plate material feed area is shortened accordingly. Therefore, the installation space for the machine can be reduced. Further, since the feed amount of the long material product in the processing feed region can be shortened, the processing accuracy can be maintained.

In the long material processing machine according to the present invention, the first and second processing means may be supported by a frame having one opening in the orthogonal direction. In the case of this configuration, when carrying the plate material into the plate material feeding area, the plate material can be carried in the direction orthogonal to the longitudinal direction without being hindered by the frame supporting the processing means. Therefore, there is no need to secure an extra space for carrying in the plate material at a position extended in the plate material feed direction from the plate material feed region of the machine, and the installation space of the machine can be further reduced.
Further, in the long material processing machine according to the present invention, the predetermined interval is a distance corresponding to a length of approximately 1/3 of a table supporting a plate material fed by the plate material feeding means, and
May be arranged at equally divided positions obtained by substantially dividing the length of the table into three. In the case of this configuration, it is possible to process a plate material having a length of about ２ of the table length. That is, when the plate material is fed in one direction so that the plate material does not protrude from the length range of the table, the range of the plate material that can be processed by the first processing means on the upper side in the feeding direction is the highest range of the plate material on the table. Side is a part that is on the better side than the first processing means when it is on the side. Further, the range of the plate material that can be processed by the second processing means is a portion that is on the lower side of the second processing means when the plate material is on the lowermost side. Therefore, by arranging the first and second processing means at the equally divided positions where the length of the table is substantially equal to three as described above, the plate material feeding direction of the machine can be used for processing the same length of plate material. Can be minimized and the installation space of the machine can be minimized.

First and second processing means 4 and 5 are provided at each equally divided position.
Is installed. Therefore, assuming that the length of the table 6 is L, the two processing means 4 and 5 are installed at an interval of (１ ／) L in the longitudinal direction of the table 6. The three sets of feed means 1, 2, 3 are arranged on the upper side of the first processing means 4, between the two processing means 4, 5 and on the lower side of the second processing means 5, respectively. I have.

Each of the machining means 4 and 5 includes upper and lower tool blocks 15 and 16 and these tool blocks 15 and 16
Block moving means 21 for moving in a direction (Y direction) orthogonal to the feed direction (X direction) of the tool, and tool driving means 14 for driving the tool 17 held by the tool block 15. As shown in FIGS. 2 and 3, the upper and lower tool blocks 15 and 16 respectively hold a plurality of punch tools 17 and die tools 18 facing each other. These tool blocks 15 and 16 are installed on the frame 13 via a guide so as to be movable in the Y direction.
And a block moving means 21 having a motor 20. Tool blocks 15 and 16 in frame 13
Can be replaced by another tool block 15, 16 stored in a tool block magazine 24 outside the machine by a tool changing device 23.

The first and second tool changers 23
Tool blocks 15, 16 supplied to the machining means 4, 5
May be of the same type. That is, the first
Tool blocks 15 and 16 installed in the machining means 15
And the tool block 1 installed in the second processing means 16
The tool blocks 15, 16 are provided with the same type of punch tool 17 and die tool 18 at all times.

The tool driving means 14 raises and lowers the ram 22 which hits the punch tool 17 with a punch driving source such as a hydraulic cylinder or a motor, and is driven forward and backward by a head moving device 27 comprising a ball screw and a motor. .

The frame 1 supporting the processing means 4 and 5
3 facing the Y direction (the side opposite to the tool change side)
Has an opening 25 for inserting a plate material so that the plate material W can be carried in a direction orthogonal to the longitudinal direction, and the frame 13 has a C-shaped side surface.

An example of the processing operation of the plate material W by the long material processing machine will be described below with reference to FIG. The length of the plate material W is set to be approximately １ ／ or less of the length L of the table 6.
Here, the left half of the plate material W is processed first, and then the right half is processed. In FIG. 5, of the plate material feeding means 1, 2, and 3, those holding the plate material W are indicated by oblique lines. The plate material W is carried on the table 6 while being deflected to the left side of the figure, as shown in FIG.
At the time of loading, each frame 13 supporting the processing means 4 and 5 has the opening 25 formed on one side in the Y direction, so that the frames 13 are not hindered by the processing means 4 and 5.
The plate material W can be carried in a direction orthogonal to the longitudinal direction. Therefore, a space for carrying in the plate material is not required in the direction in which the table 6 extends, and the installation space for the long material processing machine can be reduced accordingly.

In the state shown in FIG. 5A, the sheet feeding means 1 on the left side of the figure grips the left end portion of the sheet W and moves the sheet W toward the right side of the figure. When the intended processing portion in the left half of the plate material W comes under the first processing means 4, the plate material W
Stop feeding. Thus, the first processing means 4 is aligned with respect to the X coordinate of the processing portion. Next, the tool blocks 15 and 16 of the processing means 4 are moved in the Y direction by the block moving means 21. As a result, the selected punch tool 17 and die tool 1
8 is aligned with the Y coordinate of the processing part. In parallel with this, the tool driving means 14 is also provided with the head moving device 27.
Is positioned on the selected punch tool 17, and the processing portion of the plate material W is punched by the driving of the tool driving unit 14. With respect to other processing parts, punching is similarly performed by repeatedly feeding the plate material W to the right side by the plate material feeding means 1.

When the feed to the right side of the drawing by the plate feeding means 1 reaches the limit position limited by the first processing means 4, as shown in FIG. 5B, the plate W is fed to the intermediate position. The plate material W is further transferred to the right side in the drawing by this plate material feeding means 2 and punching is performed on the remaining processing portions by the same operation as described above. In this manner, as shown by hatching in FIG. 5B, all punching is performed on the substantially left half of the plate material W.

Next, as shown in FIG. 5C, the plate feeding means 2 at the intermediate position holding the plate W is moved to the limit position where the movement is restricted by the first processing means 4 as shown in FIG. The plate W is moved backward to the left, and the plate W is moved backward to the left until the right end thereof is substantially below the second processing means 5. In this state,
While the sheet material feeding means 2 at the intermediate position sequentially feeds the sheet material W to the right side in the drawing, the right half of the sheet material W is punched by the same operation as described above.

When the feed to the right side of the drawing by the plate feeding means 2 at the intermediate position reaches the limit position limited by the second processing means 5, as shown in FIG. The sheet material W is transferred to the right sheet material feeding means 3, and the sheet material W is further sent to the right side in the figure by the sheet material feeding means 3, and the remaining processing portions are punched by the same operation as the above case. In this way, the punching is also performed for the substantially right half of the plate material W.

As described above, in this long material processing machine, the first and second processing means 4 and 5 are provided at intervals in the longitudinal direction (X direction) of the table 6 which is the plate material feeding area. As described above, the left half and the right half of the plate material W can be processed by sharing the two processing means 4 and 5. Therefore, even when processing a plate material W of the same length, the feed amount of the plate material W by the plate material feeding means 1, 2, 3 can be smaller than in the case of one processing means, and the length of the table 6 can be reduced accordingly. Can be shortened. As a result, the length of the long material processing machine in the X direction is reduced, and the installation space for the long material processing machine can be reduced accordingly.

In particular, in this embodiment, the first and second
Are arranged at intervals of 1/3 of the length L in the longitudinal direction X of the table 6, so that the processing means 4 and 5 are (2/3) L of the length L of the table 6 at the maximum. Length of plate material W
Can be sent without protruding from the table 6 to process an arbitrary position in the entire area of the plate material W.
