In this kind of sheet material bending machine using a bend blade, a forward bending method for bending a sheet metal sandwiched between upper and lower molds upward and a lower bending method. When performing reverse bending, the blade applies not only the vertical force but also the lateral force to the plate, which is accompanied by the elastic deformation of the main frame (but the main frame is deformed. If the rigidity is high, the cost increases), and the mold is likely to be distorted in a curved shape that slightly escapes forward. When the sheet metal is bent in this state, the bending becomes insufficient as it goes to the center, and the bending becomes uneven, so that the blade is previously intentionally bent so as to be curved parallel to the distorted bending through of the mold. Was deformed and corrected, and bending was performed in the corrected state.

However, this requires trial and error, resulting in poor workability, and the thickness and bending length of the sheet metal. Therefore, it is difficult to cope with each case even if the correction amount is different, which makes it difficult to switch the correction for each type of plate material and accuracy cannot be obtained.Therefore, a correction method in which numerical data is easily obtained by a computer is adopted. Can be 4 and 5 show a conventional example thereof.

た。In the plate bending machine shown in both figures, the driving devices B1 and B1 on both sides and one driving device B2 between them are arranged with a blade holder 59 in common. The arm 63 and the longitudinal drive arm 64 are moved by crank mechanisms 67 and 69, respectively, and drive the blade holder 59 as a combination of the movements. The three transverse drive arms 63 and 6 are arranged in parallel.
One crankshaft 71 rotated by one servomotor 70 was provided for driving the motors 3 and 63. And
Regarding the blade penetrating correction device, each driving device B1,
Regarding B1 and B2, the individual crank mechanisms 60, 60, and 60 with the servomotor 74 are interposed between the horizontal driving arm 63 and the blade holder 59, so that the center and both ends of the blade holder 59 can enter and exit. By making them relatively different, the blade holder 59 is curved as shown in FIG. 4, and the curvature of the blade 53 is corrected.

適しなかった。The plate bending machine shown in FIG. 5 shows a case where the blade holder 59 is integrally supported on the longitudinal driving arm 64. In this case, If a correction device is not provided unlike the illustration, even if the horizontal axis driving arm 63 is directly connected to the blade holder 59 with a pin, a link mechanism is configured, and the blade 53 is combined with the vertical and horizontal axes. It can be moved as desired. However, as described above, since the unstable crank mechanism 60 that breaks the link mechanism is interposed as described above, it is necessary to support it as a part of the horizontal axis. An axis slider 64 was provided, and a crank mechanism 60 was provided thereon. Further, it is necessary to move the blade holder 59 up and down without being restricted by the regulation.
It was necessary to interpose the vertical slide block 72 by the LM guide between the eccentric shaft 68 and the blade holder 59, so that the number of parts became very large, which was not suitable for cost reduction.

Since the dimension L between the eccentric shaft of the crank mechanism 67 that drives the horizontal driving arm 63 in a continuous manner and the dies 55 and 56 becomes very long and the rigidity becomes poor, the bending force by the blade 53 is reduced. The main body frame 5
1, the amount of change in the dimension L is large,
Since such complicated elements are added, there is a problem that it is difficult to numerically control the computer, and that bending is not clear due to lack of rigidity.

In order to achieve the above object, a bend blade drive device that applies a bending force to a plate material tightened by an upper mold to a lower mold, a horizontal shaft driving member mainly responsible for lateral force,
As the blade holder is driven as a composite of the movement with the vertical driving member, which mainly bears the vertical force, three or more individual drives controlled by a computer are arranged side by side, and for each individual drive, Of the horizontal driving member and the vertical driving member, at least a driving mechanism for driving the horizontal driving member is provided with a crank mechanism rotated by a separate servo motor, and the horizontal driving member and the blade holder are connected. Means that the blade holder can be bent back and forth with the bend blade by the relative position of the independent positions of the eccentric shafts controlling the crank mechanism of each horizontal shaft drive in parallel with the individual drive devices by means of parallel A bend blade threading correction device in a plate material bending machine characterized by the following.

Among the parallel individual driving devices, the eccentric shaft of the crank mechanism for driving the horizontal driving member is compared for the intermediate individual driving device. Position it in front of you, and take a posture to bend as a curved shape that projects the blade with the blade holder to the center. Further, by recording this consistency in a computer, numerical data is accumulated, and based on that, an accurate set amount for each product type can be obtained. Further, since no correction means is provided in the middle of the horizontal axis, the number of parts is significantly reduced, thereby reducing the amount of correction and at the same time making the correction accurate.

In addition, while there is almost no change in the dimension from the eccentric shaft 25 as the driving source to the blade 3 on the horizontal axis, the dimension M from the eccentric shaft 25 to the dies 5 and 6 in the main body frame 1 is greatly reduced. In this case, the rigidity is given and the deformation amount of the main body frame 1 is reduced. As a result, the correction amount is reduced, and the correction by the computer control becomes accurate due to the reduction of the unstable element.

This forms a link mechanism, and the movement of the horizontal driving member 13 and the vertical driving member 14 can be combined as the movement of the blade 3. In the same sense, the horizontal driving member 13 is connected to the vertical driving member 14. Even if the pin is connected to the upper end of the
It shall not violate the spirit of the present invention.

2 can be made into a very short block shape as shown in FIG.
Since the up-and-down movement accompanying the drive of No. 7 is allowed and there is no need to use a long arm, the dimension M is also significantly reduced. Further, since the vertical movement of the blade holder 9 accompanying the driving of the longitudinal driving member 14 can be largely taken,
As shown in the embodiment, the blade holder 9 may be formed into a U-shape, and the blade holder 3 may be attached to the upper and lower sides so that the blade holder 9 can be bent forward and backward. In the conventional example, the blade holder 59 has a U-shape (FIG. 5), but there is a disadvantage that the blade holder 59 becomes unstable if it is enlarged vertically, but in the present invention, the horizontal driving member 13 directly supports the blade holder 9. To improve stability.

Not only the amount of correction is small and the correction is accurate, but also the bending can be sharpened, so that there is an excellent effect that it is suitable for bending as a non-defective product.
