BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a front stand for a folding machine, which is set in front of the folding machine and on which a metal plate to be bent is placed.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 5, a plurality of L-shaped receivers 10 each comprising a receiving plate portion 8 and a mounting shaft portion 9 are provided, and the upper and lower portions are provided at a plurality of positions on a front wall B of a folding machine. Provided with a support portion 11 having a through hole in the direction, and the mounting shaft portion 9 of the receiving tool 10 is rotatably and slidably inserted in the through hole of the support portion 11 in the vertical direction, and a screw attached to the support portion 11 The receiver 10 is fixed by tightening the mounting shaft portion 9 with 12, and the fixed receiver 1
A metal plate to be bent was placed on the receiving plate 8 of No. 0.

In the above-mentioned conventional example, when the height of the receiving tool 10 is adjusted, the screw 12 is loosened and the mounting shaft 9 is supported by the support 11.
On the other hand, the work needs to be slid in the vertical direction, and moreover, all of the plurality of receivers 10 need to be adjusted to the same height, so that the work is extremely troublesome. Further, when not in use, the receiving plate portion 8 is an obstacle in a state where the receiving plate portion 8 projects in front of the front wall B of the folding machine B.
Needs to be rotated with respect to the support portion 11 so that the receiving plate portion 8 is in a posture parallel to the front wall opening of the folding machine B, and furthermore, it is necessary to perform the work for all of the plurality of receiving members 10. Therefore, the work was extremely troublesome also in this case.

[0004]

SUMMARY OF THE INVENTION Therefore, the present invention aims to provide a front stand for a folding machine, in which the height can be easily adjusted and the front of the folding machine can be opened so as not to get in the way when not in use. And

[0005]

In order to achieve the above object, the folding machine front support of the present invention has a movable base 2 with wheels 1 and a metal plate to be bent. For supporting the table 3 and two legs 4 are crossed in an X shape and the crossing points are rotatably connected to each other, and the table is interposed between the base 2 and the table 3. Body 5 and base 2
The lower ends of the one leg 4 of the table support 5 are rotatably connected to each other and moved relative to the base 2 to narrow the gap between the lower ends of both legs 4, or It is provided with a table support body adjusting portion 6 for enlarging and a drive portion 7 for the table support body adjusting portion 6.

[0006]

When the table supporting member adjusting unit 6 is moved by the driving unit 7 to narrow or increase the distance between the lower ends of both legs 4 of the table supporting member 5, the table supporting member 5 expands and contracts in the vertical direction. The table 3 moves up and down. Further, when not in use, the wheels 1 mounted on the base 2 can be moved from the front of the folding machine to another place.

[0007]

Embodiments will be described below in detail with reference to the drawings. First, the base 2 has a rectangular hollow frame shape that is long in the lateral direction, and the wheels 1 are attached to the four corners thereof. As shown in FIG. 3, the front frame 13 of the base 2 and the rear frame 1 parallel to the front frame 13
4 is provided with guide grooves 15 and 16 on the inner surface side. A motor 18 is fixed as a drive unit 7 on a base plate 17 installed between a front frame portion 13 and a rear frame portion 14 in a substantially central portion of the base 2, and a tip of a rotation shaft of the motor 18 is fixed. A screw shaft 19 that rotates integrally is connected to the. A table support adjusting section 6 is arranged at a position near the side edge of the base 2. The table support body adjusting portion 6 has a nut 20 which is screwed with the screw shaft 19 at the central portion, and has guide grooves 15 of the front frame portion 13 and the rear frame portion 14 of the base 2 at both ends. It has rollers 21 and 22 which are fitted in 16 respectively. In the table support adjusting section 6, the motor 18 rotates and the nut 20 is screw-fed by the screw shaft 19 so that the rollers 21 and 22 roll in the guide grooves 15 and 16 and move with respect to the base 2. You can do it. Next, as shown in FIG. 2, the table support 5 has a structure in which two plate-shaped legs 4 of the same length are crossed in an X shape and the crossing points are rotatably connected. ing. Two table supports 5 are formed, and as shown in FIG. 3, they are arranged in a standing posture near the insides of the front frame portion 13 and the rear frame portion 14 of the base 2, respectively. Each table support 5 has a lower end of one leg 4 rotatably connected to the vicinity of both ends of the table support adjuster 6, and a lower end of the other leg 4 is a base. 2 front frame part 13 and rear frame part 1
4 is rotatably connected to a fixed position (see FIG. 2). Therefore, when the table support body adjusting unit 6 moves with respect to the base 2, the table support body 5 is provided on both legs 4.
By narrowing the interval at the lower end of the or expanding it in the opposite direction, the overall shape expands and contracts in the vertical direction accordingly. As shown in FIG. 4, rollers 23, 2 are provided at the upper end of the leg 4 to which the lower end of the table support 5 is fixed.
4 is attached. Next, as shown in FIG. 4, the table 3 on which the metal plate to be bent is placed is composed of a table plate 25 and a frame body 26 abutted along the peripheral edge of the lower surface thereof. Further, the rear frame portion 27 of the frame body 26
An auxiliary frame 28 parallel to the rear frame 27 is provided at a position slightly inward of the front frame 29, and guide grooves 30 and 31 are provided on the inner surfaces of the front frame 29 and the auxiliary frame 28 of the frame 26, respectively.
Auxiliary tables 32 and 33 can be attached to and detached from both ends of the table 3 in the longitudinal direction (see FIG. 1) so that the length can be adjusted according to folding machines of different sizes. The rollers 23, 24 attached to the upper ends of the legs 4 of the pair of table supports 5 are the front frame 29 of the frame 26 on the lower surface of the table 3 and the guide grooves 30 of the auxiliary frame 28. 31 are rotatably fitted into each other (see FIG. 4), and the upper ends of the other legs 4 of the table support 5 are rotatably connected to the front frame 29 and the auxiliary frame 28 at fixed positions. (See FIG. 2). Therefore, the table 3 moves up and down as the table support 5 expands and contracts in the vertical direction.

[0008]

The present invention is as described above, and the driving unit 7
Since the table 3 can be freely moved up and down by the action of the table support adjusting section 6 and the table support 5, there is an effect that the height adjustment is significantly simplified as compared with the above-mentioned conventional example.
Further, when not in use, the wheels 1 mounted on the base 2 can easily move from the front of the folding machine to another place, so that it is troublesome to rotate the receiving tool 10 out of the way as in the conventional example. There is an effect that work can be canceled. Also,
In the present invention, since the metal plate to be bent is placed on the table 3, the metal plate is more stably supported and the load is larger than that on the receiving plate portion 8 of the conventional receiving device 10. However, there is an advantage that it can be supported.
