Description

[Detailed description of the device]

[0001]

[Industrial applications]

  The present invention uses a mechanical press such as a turret punch press for slotting. Slotting in a mechanical press to perform machining (passing) The present invention relates to a punch rotating device for processing.

[0002]

[Prior art]

  Conventionally, for example, a mechanical press such as a turret punch press slats the plate material. When performing the cutting process, change the shape of the punch edge that is the die It was formed into a single shot, and single shots were continuously performed. The punch cooperates with the die to slot the plate. During the cutting process, the scraps of the plate become roll-shaped and hang down from the plate. In the final process, change the press stroke of the punch to make it bigger, The method used was to cut the scraps that had been removed.

[0003]

[Problems to be solved by the device]

  By the way, it is hydraulic type to adjust the press stroke as needed. It is easy with a press, but difficult with a mechanical press. Also press Instead of adjusting the stroke, there are dregs hanging inside the die. Rotate only the punch 180 degrees without rotating the die to cut the dregs. You could think so. However, the conventionally used mold rotating device (auto index Is designed so that the upper and lower dies (punch and die) always rotate in the same phase at the same time. It was impossible to rotate only the punch.

[0004]   The object of the present invention is to simplify the construction and to improve the above problems. Slotting even in mechanical presses where it is difficult to adjust the stroke Slotting in a mechanical press that facilitates the removal of scraps during cutting An object is to provide an industrial punch rotating device.

【Example】

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0009]   FIG. 1 is a schematic configuration diagram of an embodiment of a punch rotating device according to the present invention. In the figure The punch rotating device 1 mainly rotates the worm gear 3 and the worm gear 3. In this embodiment, the rotation comprises a worm 5 and a worm rotation drive motor 7. And drive means. The worm gear 3 is used to punch the upper turret 9. The punch 13 is rotatably attached to the attachment position by the bearing 6. Worm 5 The worm gear 3 is meshed with the worm gear 3 and is rotatably driven by the rotary drive motor 7. The gear 3 is driven to rotate 180 degrees.

[0010]   The rotatably provided punch 13 moves vertically with a constant stroke length. Provided on the die holder 15A on the lower turret 11 by a striker 17 In cooperation with the die 15, the required number of slotting processes ((1) Repeat step (3).

[0011]   At this time, as shown in FIG. 3, the part A of the punch 13 remains in contact with the die 15 even at the bottom dead center. The stroke amount is set so that it does not wrap, so the scrap 19 is a plate material. It is hanging down while being connected to W. Punch at final slotting ((4) step) Only 13 is rotated 180 degrees by the punch rotating device 1 and roll-shaped scraps 19 Are completely separated from the plate material W.

[0012]   Next, FIG. 4 is a schematic configuration diagram of another embodiment of the punch rotating device according to the present invention. . In the figure, the punch rotation device 51 is mainly composed of the upper and lower turrets 9 and 11. And the worm gears 23, 23A, 25, 25A respectively provided in the In the present embodiment in which the gears 23, 23A, 25, 25A are respectively rotated, a worm is used. 27, 27A, 29, 29A and a worm rotary drive motor 31 Moving means and worms 27, 27A, 29, 29A, and worm rotation drive motor The separating / connecting means, such as the point shafts 33 and 33A, interposed between the It is composed of operation cylinders 35 and 35A for separating and connecting the point shafts 33 and 33A. Is made.

[0013]   The worm gears 23, 23A are mounted on the upper turret 9 at the punch mounting position. 3, 13A are rotatably mounted by bearings 26, 26A. Also, the worm The gears 25 and 25A have the dies 15 and 15A at the die mounting position of the lower turret 11. It is attached so that it can rotate freely. The worms 27, 27A are the worm gears 23, 2 3A and the worm gears 23 and 2 are driven to rotate by the rotary drive motor 31. 3A is rotated 180 degrees.

[0014]   Similarly, the worms 29, 29A mesh with the worm gears 25, 25A. Rotated by the rotary drive motor 31, the worm gears 25 and 25A are rotated 180 degrees. It is driven to rotate.

[0015]   Incidentally, 37, 37A and 39, 39A are shafts, and 41, 43 are rotationally driven. Gears for transmitting the rotation of the motor 31, 45 and 47 are rotations of the rotary drive motor 31. With a pulley and a timing belt for transmitting each to the shafts 37 and 37A. , 49A are solenoid valves for operating the operating cylinders 35, 35A.

[0016]   As shown in FIG. 5, the punch rotation device 21 configured as described above is a conventional die. The operating cylinders 35 and 35A are the same at the same time as a rotating device (auto index). The shafts 33, 33A and the shafts 37, 37A and the shafts 33, 33A. The operation cylinder 35 can be separated and connected with the YAFT 39, 39A. Only the shafts 37 and 37A are connected to operate the rotary drive motor. The driving force of the motor 31 can be transmitted to the punches 13 and 13A to rotate the punches. Therefore, if the point shafts 33 and 33A are connected together, the porosity of the conventional mold rotating device is increased. If only the front shaft 33 is connected, one of the punches 13 in the final slotting punch is It is rotated by 80 degrees.

[0017]   In addition, as shown in FIG. 6, the point shafts 33 and 33A are separated and joined at the same time. It is assumed that the front shaft 33B is independently separated and connected. Therefore, the point axes 33, 3 If 3A and 33B are connected together, it operates as a conventional mold rotating device, and the point shaft 3 If you connect 3, 33A and separate the point axis 33B, the final slotting slot When punching, the punches 13 and 13A are rotated by 180 degrees.

[0018]   As mentioned above, in the mechanical press where the press stroke cannot be adjusted. Also, the slotting process can be easily performed, and the conventional mold rotating device can be used for punch rotation. As the device, the punch 13 alone is configured to rotate 180 degrees independently. is there.

[0019]   It should be noted that the present invention should not be limited to the above-mentioned embodiment, and appropriate design changes may be made. It can also be carried out in other embodiments by further modification, for example, barley. A bevel gear or the like may be used instead of the ya, and simply the upper and lower turrets. Separate drive sources for driving the worm gears may be provided.

[0020]

[Effect of device]

  As is clear from the above description, the mechanical press of the present invention has a The punch rotator for the rotting process is the punch mounting position of the upper turret. A worm gear for mounting the punch is provided, and the worm gear is rotatably driven to move the punch. By providing a rotation drive means for rotating the upper part by 180 degrees, or by Each turret is provided with a worm gear, and the worm gear is driven to drive the worm gear. The worm is provided with a rotation driving means for rotating the punch and the die simultaneously in the same phase. The worm gear and the rotary driving means are separately provided between the gear and the rotary driving means. The problem of the prior art by providing a separate coupling means for separating or coupling Is effectively solved, its configuration is simple, and the press stroke is difficult to adjust. Even mechanical presses can easily handle scraps during slotting. Become.
