Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a plate-like work cutting machine such as a cutter machine for cutting a disk from a metal plate.

[0002]

[Prior art]

 In a conventional plate-shaped workpiece cutting machine, as shown in FIG. 4, a horizontal U-shaped portion 22 (bow-shaped portion) having a work escape space 21 inside is formed in the machine body b.

A work holding body 24A is provided at an upper end portion 22A of an arcuate portion 22 of the machine body b so as to be able to move up and down, and a support rotary table 24B is provided at a lower end portion 22B. The work 23 is supported and held by the lowered work pressing body 24A, and a part of the work 3 is placed in the work escape space 21. It is a structure that supports and fixes between 22B.

By rotating the support plate 24B, a cutter blade portion (cutting mechanism) 25 provided in the machine body b cuts a circular plate, for example, in a circular shape to cut out a disc from the plate-shaped work 23.

[0005]

[Problems to be solved by the device]

 However, since the conventional plate-shaped workpiece cutting machine has a configuration in which the cutting mechanism 25 including a cutter blade portion is provided outside the bow-shaped portion 22, that is, at a position facing the workpiece escape space portion 21 on the inside, When positioning 23, the bow-shaped part 22 of the machine body b and the cutting mechanism 25 must be positioned so that they can be seen while looking into it from the side, which makes positioning very difficult and the work efficiency is poor. .

The present invention solves such problems and makes it possible to construct the apparatus compactly, and at the same time, the work operations such as setting, positioning, and taking out of the work become easy, and the work efficiency is improved. The purpose is to provide an excellent plate cutting machine.

[0007]

[Means for Solving the Problems]

 The gist of the present invention will be described with reference to the accompanying drawings.

The horizontal U-shaped part 2 having the work escape space 1 inside is provided on the machine body a, and the upper tip 2A and the lower tip 2B of the horizontal U-shaped part 2 are pressed against the work 3 to rotate. A work rotation mechanism 4 is provided to allow a part of the work 3 to be inserted into the work escape space 1 between the upper tip 2A and the lower tip 2B of the horizontal U-shaped portion 2 by the work rotation mechanism 4. In the cutting machine for plate-like workpieces, in which the workpiece 3 is arranged in the arranged support state, and the workpiece rotating mechanism 4 cuts the workpiece 3 which rotates horizontally into a predetermined shape in the machine body a, The cutting mechanism 5 is arranged on the side of the work escape space 1 inside the U-shaped portion 2, and the work 3 is extended from between the upper tip 2A and the lower tip 2B of the lateral U-shaped portion 2 to the outside thereof. Place the work table 6 that is horizontally supported outside the horizontal U-shaped part 2. The present invention relates to a plate-shaped workpiece cutting machine characterized by being horizontally projected toward the side.

[0009]

[Action]

 The work table 6 is used to rotate the work while a part of the work 3 is placed in the work escape space 1 between the upper tip 2A and the lower tip 2B of the horizontal U-shaped portion 2 (bow-shaped portion). The work 3 is positioned and fixed by the mechanism 4.

In this state, the work 3 is placed on the work rotating mechanism 4 via the work table 6, and the work 3 supported by the work rotating mechanism 4 is rotated by the work rotating mechanism 4 and cut by the cutting mechanism 5.

[0011]

【Example】

 In this embodiment, the machine body a has a horizontal U-shaped portion 2 (bow-shaped portion) in which a work escape space portion 1 is formed toward the back side (inner side), and an upper portion of the horizontal U-shaped portion 2 is formed. A work rotating mechanism 4 for pressing and rotating the plate-like work 3 is provided between the tip 2A and the lower tip 2B.

In this work rotating mechanism 4, a work holding portion 4A is provided at an upper tip portion 2A so as to be able to move up and down, a support rotation portion 4B is provided at a lower tip portion 2B, and the work holding portion 4A is lowered to move the work rotation portion 4B above. The work 3 arranged in the above is pressed down to rotate the bearing rotating portion 4B to rotate the work 3.

A cutting mechanism 5 that cuts out and cuts the rotating work 3 into a circular shape is arranged on the bow portion 2 side (the inner work escape space portion 1 side) of the machine body a. By accommodating it on the side, the machine body a itself is made compact, and the outer side of the bow-shaped part 2 on the front side of the work is opened.

In this embodiment, a work table 6 for work that horizontally projects outward from between the upper tip portion 2A and the lower tip portion 2B is arranged on the open front side (front side). At a predetermined position of the work table 6, an escape window hole 7 for arranging the bearing rotating portion 4B is formed.

Therefore, in the present embodiment, in the manual operation, it is possible to easily set the work 3 between the upper tip portion 2A and the lower tip portion 2B by using the work table 6 provided on the front side where the worker stands. Moreover, since the outside is opened from between the upper tip 2A and the lower tip 2B, the positioning set by the work rotating mechanism 4 can be set accurately by visual observation from the front, and the work efficiency is remarkably improved. .

Further, in the present embodiment, a work moving arm 8 for loading and unloading a work is provided on the left side of the work table 6 in the drawing, and a cutting plate after cutting a disc from the work 3 is provided on the right side. A notch removing arm 9 for removing the notch is provided.

Therefore, the work moving arm 8 swivels to set the work 3 that has been sucked and held on the bearing rotating portion 4B of the work table 6 apart from the work moving arm 8 and is retracted again after cutting. The arm 8 swivels to adsorb the disc that has been cut, and retreats by swiveling to take out the workpiece 3 (disc) after cutting.

On the other hand, for the cut after cutting, the cut removal arm 9 that has been retracted is swung, and the cut removal arm 9 is retracted with the catch hooked at the lower end of the cut removal arm 9 being hooked. It is possible to swivel and remove the cut from the work table 6.

As described above, the work moving arm 8 and the notch removing arm 9 are easily attached by being configured to be open outward from between the upper tip 2A and the lower tip 2B. As a result, it becomes a plate-shaped workpiece cutting machine that can easily automate the supply and removal of workpieces.

In the cutting mechanism 5 of this embodiment, the movable rotary blade portion 5B is provided so as to be movable up and down with respect to the rotary blade portion 5A, and the movable rotary blade portion 5B is temporarily lowered to a position where it contacts the work 3 with a constant pressure. After the work 3 is rotated several times, the work 3 is further lowered to rotate the work 3 into a circular shape.

As compared with the method of gradually lowering the rotary movable blade portion 5B, even a thick work can be favorably cut without distortion.

In the figure, reference numeral 10 is a workpiece positioning claw, 11 is a groove in which a lateral positioning claw (not shown) projects, 12 is an adjustment handle for moving and adjusting the work table 6, and 13 is a bearing rotating portion 4B. It is an adjustment handle that adjusts up and down.

[0023]

[Effect of device]

 Since the present invention is configured as described above, by disposing the cutting mechanism on the side of the horizontal U-shaped portion (bow-shaped portion) having the work escape space, the entire device can be made compact and the bow-shaped portion Since the outer side of the work escape space is open, positioning of the work is facilitated, and an automatic feeder and an automatic ejector as in the embodiment are easily attached.

Further, since the work table is provided on the outer side of the open bow-shaped portion, the workability is further improved, and the plate-like work cutting machine is extremely practical.
