Floating dies can be used as the processing dies 1a, lb...-1f, which are mounted on a rotary table 3 as shown in FIG. 3 to facilitate exchange with other types of dies.
It is preferable to position and lock the die base plate 11 with a pair of left and right die guides 31 attached to the plate surface of the plate, and to fix the die base plate 11 with a plurality of rotation stoppers 32.

As shown in FIG. 4, this floating die 1a includes a fixed die 13a and a movable die 13b on a die plate 12, among which a long member W is fixed during the operation of the processing die, and the movable die 13b is opened after the operation. An actuator 14, such as a cylinder, is detachably attached with a one-touch connector so as to be in close proximity to the fixed die 13a when holding a long member.
is equipped with a connection. Further, a plurality of guide posts 15 are implanted in the die plate 12, and a punch 17 is attached to a punch plate 16 that is supported by the guide posts 15 so as to be movable up and down. The punch 17, the fixed die 13a, and the movable die 13b work together to cut a long member into predetermined notches, punch holes, etc. by the pressure of the press machine 5, and each process is performed according to the processing. Type 1a, lb

It can be attached and detached with one touch.

The gear 6 meshing with the inner peripheral edge of the rotary table 3 can be configured to be driven intermittently using a drive motor 60 as shown in FIG. The drive motor 60 is preferably equipped with a speed reducer to increase rotational torque. The drive mechanism is a rotating shaft 6 of a drive motor 60 as shown in FIGS. 7 to 9.
A rotary plate 61 is mounted on the shaft 0a, and a pin 62 protruding from the eccentric position of the rotary plate 61 is fitted into a cam groove 63a provided on the plate surface of the horizontal movable plate 63. A rack bar 65 supported in parallel by a holding part 64 on the left and right ends is arranged to mesh with a pinion 66, and this pinion 66
can be constructed by attaching it to the drive shaft 68 of the one-way clutch 67 that is integrally attached to the gear 6. Incidentally, an internal gear 33 with which the gear 6 meshes is mounted on the inner peripheral edge of the rotary table 3, as shown in FIG.
Further, it is preferable to form a perfect circular arc surface 34 on a part thereof so as to be arranged in sliding contact with a guide plate 35 fixedly installed inside the rotary table 3.

The lifting mechanism 9 attached around the outer circumference of the rotary table 3 is constructed by attaching support plates 91 to appropriate locations on the base frame 4 as shown in FIG.
A piston part 94, which is prevented from rotating by a guide pin 93, is disposed between the cylinder part 92 combined with the piston part 92, and a supply nozzle 95 that applies air pressure or the like to the piston part 94 is connected to the cylinder part 92. It can be constructed by equipping the tip side of the roller 94 with a roller 96 such as a ball or a cylindrical radial bearing. In this lifting mechanism, when fluid pressure is applied to the piston part 94 from the supply nozzle 95 during intermittent rotation of the rotary table 3, the piston part 94 floats inside the cylinder part 92 and presses the roller 96 against the bottom surface of the rotary table 3. As a result, as shown in FIG. 12, the rotary table 3 can be lifted up by a small amount, so that the rotary table 3 can be rotated with less resistance simply by contacting only the rollers 96. Also,
The above-mentioned processing molds 1a, lb...1f and position detection tool 19
The energy receiving parts 10a, 10b...10f are the first
As shown in FIG. 3, a socket holder 100 is mounted on the rotary table 3, and this holder 100 connects the connection passage 1 between the electrical socket side contact 101 and the air tube 102.
03. On the other hand, energy supply paths 71 and 72 derived from the controller 7
On the side connected to the base frame 4, an air cylinder 74 is fixed with a support bracket 73 attached to an appropriate position on the base frame 4, preferably at a corresponding vicinity of the vertically movable pressing part 51 of the press machine 5 as shown in FIG. Connect the plug holder 5 to the tip of the rond 74, and insert it into the plug holder 75.

It can be constructed by equipping a plug-side contact 77 energized by a ring 76 and a cylindrical air supply connector 78 made of urethane or the like with good sealing properties. These energy receiving parts 1
As shown in FIG. 14, when the rotation of the rotary table 3 stops, the air cylinder 74 is moved to extend its stroke, and the contacts 101.77 and the passage 103 on the socket side and the plug side are connected to the energy supply paths 71 and 72, as shown in FIG.゛8
By connecting these, the processing molds 1a, lb, . . . 1f can perform predetermined operations and detection, that is, confirm the presence of the end of the elongated member and fix it to the processing mold.

In the rotary press device configured in this way, the processing dies 1a, l are moved intermittently by the rotation of the rotary table 3 while the long member W is held in a fixed position without being moved.
It is only necessary to insert and remove the terminal end of the elongated member W from b...1f and rotate it, and processing as shown in FIG. 15 can be sequentially applied to the end of the elongated member W in accordance with the insertion and removal. Note that in the figures (15a to 15f), the elongated member W is shown always maintaining the same posture, but in this embodiment, the elongated member W is rotated about its axis to perform a predetermined processing die. Since it is inserted into &)2+, the vertical movement of the pressing part 51 of the press machine 5 can be directly used as it is, and the structure of the processing die can therefore be further simplified. This molding process is performed by, for example, a long member W in which a synthetic resin is integrally extruded on the surface of a metal core material by composite extrusion molding or the like as shown in FIG. 15a. Trim processing t2+cutting processing C, trim processing t3. Earring processing P
can be applied as shown in the order of each figure. Each processing die 1a moves toward or away from a predetermined position where the elongated member W is taken in and taken out in accordance with this processing order.

1b...1f may be moved intermittently, and the movement control can be easily performed using the rotary table 3 described above.

This rotary table 3 is configured such that when one pulse of current is passed through the drive motor 60 according to a command from the controller 7, the drive motor 6
When the rotation shaft 60a of 0 rotates once, it rotates by a predetermined angle. That is, as the rotating shaft 60a of the drive motor 60 rotates once, the rotating plate 61 also rotates once, but on the way, the pin 62 is inserted into the cam groove 63a of the horizontally moving plate 63 as shown in FIG.
The horizontal moving plate 63 is moved to the left by continuously moving half a turn from near the middle of the cloth to above and from above to near the middle of the cloth, and this movement also causes the rack bar 65 to move leftward. From there, the clutch 67 is rotated clockwise together with the pinion 66. At that time, the clutch 67 is connected to the drive shaft 68
The gear 6 rotates by meshing between the bearing side of the rotary table 3 and the mounting side of the gear 6, thereby rotating the rotary table 3 at a predetermined angle. Detecting this point, the brake 8 is activated to stop the rotation of the rotary table, but the drive motor 60 rotates another half turn, and the pin 62 continues to move along the cam groove 63a of the horizontally moving plate 63. When the horizontal moving plate 6 is rotated half a turn downward from near the middle of the cloth and from below to near the middle of the cloth.
3 moves to the right and the rack bar 65 also moves to the right, causing the pinion 66. Rotate the clutch 67 counterclockwise. At that time, the clutch 67 disengages the shaft bearing side of the drive shaft 68 and the mounting side of the gear 6, thereby idling in the opposite direction, and does not transmit the driving force to the rotary table 3 from where the gear 6 is not rotated. Therefore, in this drive mechanism, if the operation of each mechanical part is represented by a diagram, even if the rotation angle of the motor drive shaft is continuously rotated in one rotation as shown in FIG. The moving speed of the rack bar 65 is '! Since the state shown in Fig. J117 is reached and the circumferential speed of the rotary table 3 becomes slower at the start and stop of rotation as shown in Fig. 18, less torque is required when starting the motor rotation shaft 60a, and the drive motor This is preferable because no overload is applied to the brake 60 and no strong pressing force is required on the brake 7 for stopping the rotary table.

In addition, although this example has been described as having six processing dies, if the molding process is completed with 5 or 4 processing dies, the 5th or 4.5th processing die may be used. It is also possible to electrically control the rotary table so that it skips instead of stopping at the position of the mold.

Effects of the Invention As described above, the rotary press device according to the present invention not only greatly reduces the burden on workers, but also supports automation and enables efficient end processing of long members. It is something to do.
