  However, in the press working apparatus described in the background art, when a press unit for the car type D as well as the car type A, the car type B, and the car type C is added, if the installation space cannot be secured on the bed, a new press working apparatus is provided. There is a problem that a new installation space is required in the factory.

  In the turret punch press described in the background art, since the opposing surfaces of the upper turret 100 and the lower turret 200 are provided in parallel with each other, a press panel having a three-dimensional shape as shown in FIG. In the case of P10, after the three-dimensional shape press panel P10 is moved to the punching processing position PP or the three-dimensional shape press panel P10 is set at the punching processing position PP, the three-dimensional shape press panel P10 is applied to a plurality of locations. When the upper turret 100 and the lower turret 200 are indexed and rotated in order to punch holes of different shapes and sizes, the portion A of the three-dimensional shape press panel P10 (the circle of the two-dot chain line indicated by A) ) And the location of location B (the location of the circle indicated by the two-dot chain line indicated by B) protrudes, The three-dimensional shape press panel P10 in the punch unit 110 and the die unit 210 except the PP had difficulties may interfere.

When the three-dimensional shaped press panel P10 interferes with the punch unit 110 or the die unit 210, there is a difficulty in that the three-dimensional shaped press panel P10 is damaged or misaligned, resulting in a decrease in punching accuracy.
Therefore, since a new turret punch press corresponding to the three-dimensional shape of the press panel P10 has to be provided, a new installation space is required in the factory.

The present invention has been made in order to solve such a conventional problem, and in addition to a press panel having a planar shape, a press panel having a three-dimensional shape, a hole or a bending having a different shape or size. It is an object of the present invention to provide a turret punch press capable of performing the above-described press working with a single machine.
Another object of the present invention is to provide a turret punch press that can also ensure the accuracy of press processing of a press panel.

A turret punch press according to a first aspect of the present invention that achieves the above-described object is an upper turret formed in a disc shape and mounted with a plurality of upper die units for pressing at predetermined intervals in the circumferential direction on the outer peripheral side. A lower turret formed in a disk shape and having a plurality of lower die units for press working corresponding to the upper die units for press working, and the upper turret and the lower turret are rotated to the press working position. A hammer driving device for striking a striking pressure portion of one indexing upper mold unit with a hammer member, and one press working lower mold unit indexed and positioned at the pressing position. A lower mold receiver located below one press working lower mold unit, an upper turret are rotatably provided, and a hammer driving device is provided above the upper turret. A frame having a frame upper part, a lower turret provided rotatably, and a lower mold receiver provided below the lower turret, and a frame pedestal for connecting the frame upper part and the frame lower part rearward In the turret punch press equipped with the upper turret, the upper turret and the lower turret are spaced so that the distance between the upper turret and the lower turret is set at the front of the upper part of the frame and the lower part of the frame and becomes wider toward the frame pedestal. The rotating shaft of the lower turret and the rotating shaft of the lower turret are inclined, and the upper die unit for press processing mounted on the upper turret and the lower mold unit for press processing mounted on the lower turret are opposed to each other at the press processing position. When the lower turret is rotating, the upper surface of the lower mold receiver is arranged to perform the pressing process. A first inclined surface portion that gradually raises the one press working lower die unit as the die unit approaches the pressing position, and the one press working lower die unit that gradually rises at the first inclined surface portion. A horizontal plane part held at the height position at the press working position, and a second inclined surface part that gradually lowers the one press working lower mold unit from the height position of the horizontal plane part as the distance from the press working position increases. A material handling robot that has a suction pad that can absorb the press panel formed and pressed at the press processing position and moves the press panel sucked by the suction pad and the press panel are set and positioned at the press processing position. And a material handling frame provided with a positioning plate with perforated holes. Is formed with a flange for fitting the hole of the positioning plate and setting the press panel at the press working position via the material handling frame .

  According to the turret punch press as the first aspect as described above, the distance between the upper turret and the lower turret is the narrowest at the set pressing position in front of the upper part of the frame and the lower part of the frame. The rotation axis of the upper turret and the rotation axis of the lower turret are inclined so that the space between the upper turret and the lower turret can be increased on the frame leg pillar side of the frame. When the lower turret is rotating on the upper surface of the lower mold receiver positioned below the one lower pressing unit positioned and positioned at the pressing position, one lower pressing unit is at the pressing position. As it approaches, the first inclined surface portion that gradually raises the one press working lower die unit and the first inclined surface portion gradually rises. The one lower die unit for press processing is held at the height position at the press processing position, and the one lower press unit for press processing is gradually increased from the height position of the horizontal surface portion as the distance from the press processing position is increased. Since the second inclined surface portion to be lowered is formed, one lower press working unit located at the press working position can perform press working with the corresponding upper working die unit. The plurality of other lower die units for press working that are located at positions other than the press working position can be lowered from one lower die unit for press working located at the press working position.

  Therefore, after moving the 3D-shaped press panel to the pressing position or setting the 3D-shaped press panel to the pressing position, holes or Even if the upper turret and the lower turret are indexed and rotated to perform press processing such as bending, the three-dimensional shape press panel is placed on the upper mold unit for press processing and the lower mold unit for press processing at positions other than the press processing position. Interference can be prevented.

Further, since one press working lower die unit can be protruded so as to be able to be pressed with the corresponding press working upper die unit at the press working position, In order to form a flange and use this flange for positioning the material handling frame, a positioning plate with a hole that fits into the flange of the lower die unit for press processing is provided on the material handling frame to ensure the accuracy of press processing. Can also be achieved.
In addition, a punch unit and a die unit are applied to the upper die unit for pressing and the lower die unit for pressing when the pressing is punching.

  The punch guide 71 has a flange 71a formed on the upper portion thereof, and functions as a stopper serving as a lower limit of insertion when the punch guide 71 is inserted into the upper turret hole 21 of the upper turret 2. The punch 72 includes punch bodies 72a and 72b serving as blades, a flange 72c serving as a punch head, and a punch driver 72d provided with punch bodies 72a and 72b at a lower portion and a flange 72c at an upper portion. The return spring 73 is fitted so as to cover the punch driver 72 d of the punch 72 and is interposed between the flange 72 c of the punch 72 and the flange 71 a of the punch guide 71. Further, the punch guide 71 has holes for projecting the punch bodies 72a and 72b of the punch 72. In FIG. 1B, the punch bodies 72a and 72b are composed of three pins, the center pin 72a is large and the other two pins 72b and 72b are small, but the shape is other shapes. Needless to say, it may be.

  In such a configuration, when the hammer driving device 4 described later lowers the hammer member 41 and hits the flange 72c of the punch 72, the punch 72 descends against the elastic force of the return spring 73. When 4 raises the hammer member 41, the punch 72 is raised by the elastic force of the return spring 73.

  As shown in FIG. 1A, the lower turret 3 is formed in a disc shape and is a plurality of lower die units for press working at predetermined intervals in the circumferential direction at the outer peripheral portion, for example, a die 8 is mounted so as to be movable up and down. Yes. Specifically, the die unit 8 is mounted in the outer turret 3 in a plurality of lower turret holes 31 (see FIGS. 3 and 4) provided at predetermined intervals in the circumferential direction so as to be movable up and down. When the punch unit 7 is configured as shown in FIG. 1B, the die unit 8 has a flange 81 formed at the upper portion and is inserted into the lower turret hole 31 of the lower turret 3 as shown in FIG. It functions as a stopper that becomes the lower limit of insertion when The die unit 8 is provided with die holes 82a and 82b at positions corresponding to the punch bodies 72a and 72b in the die unit 8. The punch body 72a is formed in the die hole 82a, and the punch body 72b is formed in the die hole 82b. By inserting, punching processing (press processing) can be performed on the three-dimensional press panel P (see FIGS. 5A and 5B).

  It should be noted that a side surface that fits into the upper turret hole 21 of the punch guide 71 of the punch unit 7 and a side surface that fits into the lower turret hole 31 of the die unit 8 are cut out to surround the punch unit 7 and the die unit 8. By using the stopper, the punching shape can be made into a square hole other than a round hole, or various types of pressing such as burring and bending.

  As shown in FIG. 4, the upper turret 2 and the lower turret 3 are indexed and rotated in synchronization with each other by drive mechanisms 22 and 32 that rotate a rotating shaft by a servo motor, and the upper turret according to the index number. A hole 21 and a lower turret hole 31 are provided.

  Further, as shown in FIGS. 1, 4, 5, and 6A, the upper turret 2 and the lower turret 3 are connected to the frame upper portion 61 and the frame via the drive mechanisms 22 and 32 so that the opposing surfaces are inclined. It is provided in the lower part 62. Specifically, the distance between the upper turret 2 and the lower turret 3 is such that the punching position set in front of the frame upper portion 61 and the frame lower portion 62 is the narrowest and becomes wider toward the frame leg portion 63. The rotation shaft 22a of the upper turret 2 and the rotation shaft 32a (see FIG. 4) of the lower turret 3 are inclined.

  As described above, when the upper turret 2 and the lower turret 3 are provided on the upper frame portion 61 and the lower frame portion 62 so that the opposing surfaces are inclined, the punch units 7 and the lower turret mounted on the upper turret 2 are provided. Each die unit 8 mounted on 3 is disposed so as to face the punching position PP set in front of the frame upper part 61 and the frame lower part 62 and perform the punching process. As a result, the punch 72 of the punch unit 7 of the upper turret 2 is struck by the hammer member 41 of the hammer driving device 4 at the punching processing position PP, and performs punching in cooperation with the die unit 8 at the opposing position. Will be able to.

  As shown in FIGS. 1A, 3, and 4, the hammer driving device 4 rotates the upper turret 2 and the lower turret 3 so that the punch 72 of one punch unit 7 is indexed and positioned at the punching processing position PP. Is hammered by the hammer member 41. Specifically, the hammer member 41 is fixed to the tip of the piston rod 42a of the flange-type cylinder 42 provided on the upper surface of the frame upper portion 61, and the hammer member 41 operates the punch unit by the stroke operation of the piston rod 42a of the flange-type cylinder 42. 7 punches 72 can be pressed.

  When the upper die unit for press working and the lower die unit for press working are the punch unit 7 and the die unit 8, the lower die receiver 5 becomes the die receiver 5, and FIG. 1, FIG. 2, FIG. 3, FIG. 6 (A) and 6 (B), it is located below one die unit 8 so as to abut on one die unit 8 indexed and positioned at the punching processing position PP. Specifically, it is located below the lower turret 3 and is provided on the upper surface of the frame lower part 62. When the lower turret 3 rotates, the upper surface of the die receiver 5 has a first inclined surface portion 5a that gradually raises the one die unit 8 as the one die unit 8 approaches the punching position PP, The one die unit 8 gradually rising at the first inclined surface portion 5a is held at the height position at the punching processing position PP, and the one die unit 8 is moved away from the punching processing position PP. The second inclined surface portion 5c is gradually lowered from the height position of the horizontal surface portion 5b. When the rotation direction of the lower turret 3 is reversed, the second inclined surface portion 5c gradually raises one die unit 8, and the first inclined surface portion 5a gradually lowers one die unit 8. I will let you.

  Further, the turret punch press 1 of the present invention is a three-dimensional punching process at a punching position PP as shown in FIGS. 1 (A), 2, 3, 4, 5, 5 (A) and 5 (B). A material handling robot (not shown, hereinafter referred to as a material handling robot) having a suction pad (not shown) capable of sucking the shape press panel P and moving the three-dimensional shape press panel P sucked by the suction pad. And a material handling frame 9 provided with a positioning plate 91 in which a three-dimensional press panel P is set and a hole 91a for positioning at a punching position PP is provided. As this material handling robot, for example, a multi-joint type material handling robot in which a plurality of arms are respectively connected at joints and a suction pad is provided at the tip arm is applied. Further, as shown in FIGS. 1C and 4, the die unit 8 is fitted with the hole 91a of the positioning plate 91, and the three-dimensional press panel P is set at the punching processing position PP through the material handling frame 9. A flange 81 is formed. As described above, the flange 81 also functions as a stopper serving as a lower limit of insertion when the flange 81 is inserted into the lower turret hole 31 of the lower turret 3. The material handling frame 9 is provided with positioning pins 92 and 93 for setting the three-dimensional press panel P on the frame.

The operation of the turret punch press 1 configured as described above will be described below.
First, a necessary number of punch units 7 are mounted in a plurality of upper turret holes 21 of the upper turret 2 on a three-dimensional press panel P to be punched, and each punch is inserted into a plurality of lower turret holes 31 of the lower turret 3. A die unit 8 corresponding to the unit 7 is mounted. Further, the material handling frame 9 on which the three-dimensional shape press panel P before punching is set is placed on a work table (not shown).

  In order to punch the three-dimensional shaped press panel P with the upper turret 2 and the lower turret 3 on which a predetermined number of punch units 7 and die units 8 are mounted, a three-dimensional shape that performs a predetermined punching process at the punching position PP. A pair of punch units 7 and a die unit 8 corresponding to the press panel P is selected from the upper turret 2 and the lower turret 3, and the pair of punch units 7 and the die unit 8 are set in front of the frame upper part 61 and the frame lower part 62. The drive mechanisms 22 and 32 of the upper turret 2 and the lower turret 3 are indexed and rotated so as to move to the punching processing position PP. At this time, when the lower turret 3 rotates and the corresponding die unit 8 approaches the punching position PP, the die unit 8 is inserted into the lower turret hole 31 so as to be movable up and down. Since the lower surface of the die gradually rises up the first inclined surface portion 5a of the die receiver 5 and is placed on the horizontal surface portion 5b at the punching processing position PP, the die unit 8 is held at the height position. Accordingly, since the corresponding punch unit 7 mounted on the upper turret 2 and the corresponding die unit 8 mounted on the lower turret 3 are arranged to face each other at the punching processing position PP, the pair of punch units 7 and the die unit Since the center lines of 8 coincide, punching can be performed.

  In this state, the three-dimensional press panel P set on the material handling frame 9 placed on the work table is sucked by the material handling robot with the suction pad and moved between the upper turret 2 and the lower turret 3. At this time, since the die unit 8 is raised by the die receiver 5 at the punching position PP of the lower turret 3, the hole 91 a of the positioning plate 91 provided in the material handling frame 9 is fitted into the flange 81 of the die unit 8. Thus, the three-dimensional press panel P can be accurately set at the punching position PP.

  When the hammer driving device 4 is driven, the hammer member 41 descends and presses the punches 72a and 72b of the punch unit 7, so that a punching process is performed on the three-dimensional press panel P between the pair of punch units 7 and the die unit 8. Can be applied.

  In this state, in order to move the pair of punch units 7 and die unit 8 different from the pair of punch units 7 and die unit 8 to the punching processing position PP, the drive mechanisms of the upper turret 2 and lower turret 3 are moved. Synchronize and rotate the index. At this time, the lower surface of the die unit 8 positioned at the punching processing position PP gradually descends the second inclined surface portion 5c of the die receiver 5 and comes out of the second inclined surface portion 5c, so that it is positioned at the punching processing position PP. It can be lowered from the die unit 8. Further, in the die unit 8 for performing punching processing, when the lower turret 3 rotates and approaches the punching processing position PP, the lower surface gradually rises the first inclined surface portion 5a of the die receiver 5 and punching processing is performed. Since it is placed on the horizontal surface portion 5b at the position PP, the die unit 8 can be held at the height position. Therefore, the punching process can be performed.

The material handling frame 9 on which the punched three-dimensional shape press panel P is set is placed at a predetermined position of a shooter (not shown) for conveying from the turret punch press 1 by the material handling robot.
Such operations of the turret punch press 1 and the material handling robot are performed by control by a control system.

  In this way, the interval between the upper turret 2 and the lower turret 3 is such that the punching processing position PP set in front of the frame upper part 61 and the frame lower part 62 is the narrowest and becomes wider toward the frame leg part 63. Since the rotation shaft 22a of the upper turret 2 and the rotation shaft 32a of the lower turret 3 are inclined, the space between the upper turret 2 and the lower turret 3 on the frame leg post 63 side of the frame 6 can be increased. When the lower turret 3 is rotating on the upper surface of the die receiver 5 positioned below the one die unit 8 indexed and positioned at the punching processing position PP, one die unit 8 approaches the punching processing position PP. As the first die unit 8 gradually rises, the first inclined surface portion 5a and the first inclined surface portion 5a gradually move upward. The horizontal unit 5b that holds the one die unit 8 at the height position at the punching processing position PP, and the one die unit 8 gradually from the height position of the horizontal plane unit 5b as the distance from the punching processing position PP increases. Since the second inclined surface portion 5c to be lowered is formed, one die unit 8 located at the punching processing position PP can be projected so as to be able to perform punching processing with the corresponding punch unit 7. A plurality of other die units 8 positioned other than the punching position PP can be lowered from one die unit 8 positioned at the punching position PP.

  Therefore, after moving the three-dimensional shape press panel P to the punching processing position PP or setting the three-dimensional shape press panel P to the punching processing position PP, different shapes or Even if the upper turret 2 and the lower turret 3 are indexed and rotated to perform punching of a hole having a large size, the three-dimensional shape press panel P is applied to the punch unit 7 or the die unit 8 at a position other than the punching processing position PP. Interference can be prevented.

  Therefore, as shown in FIG. 6 (A), since a plurality of types of large press panels P, P1 having a three-dimensional shape can be punched with one turret punch press 1, The equipment can be reduced and space saving can be realized. Accordingly, it is possible to increase product variations at a lower cost than before.

  Further, at the punching position PP, one die unit 8 can be projected so as to be punched with the corresponding punch unit 7, so that a flange 81 is formed on the die unit 8, and this flange is formed. In order to use 81 for positioning the material handling frame 9, the positioning plate 91 provided with a hole 91a that fits into the flange 81 of the die unit 8 is provided in the material handling frame 9, so that the accuracy of punching can be ensured. It becomes like this.

In addition, the punch unit 7 and the die unit 8 are not limited to those having the configurations shown in FIGS. 1B and 1C, but are arranged to face each other at the punching processing position so that the center lines of the punch unit and the die unit coincide with each other. Any configuration can be used as long as punching can be performed. The upper die unit for press working and the lower die unit for press working are not limited to punching units and die units for punching, and can be configured to perform shearing and bending such as punching and edge cutting, which are press working. It may be.
Needless to say, the turret punch press 1 is not limited to a three-dimensional press panel, and can be pressed by a flat press panel.

  Although the present invention has been described with the specific embodiments shown in the drawings, the present invention is not limited to the embodiments shown in the drawings, and is known so far as long as the effects of the present invention are achieved. It goes without saying that any configuration can be adopted.
