[0024] A guide side plate is provided on one side (the right side in FIG. 2) of such a lower frame 19. 129 is provided, and the side surfaces located above this guide side plate 129 have Y-axis Die holder moving support members 131 are fixed in parallel in the direction. This Daiho A die holder sliding support member 133 is attached to the die holder moving support member 131. The die holder moving support member 133 has a ball for moving the die holder in the Y-axis direction. A movable member 135 is provided which is screwed into the screw 33. This movable member 135 has a A support shaft 139 is protruded from the upper surface of the protrusion plate 137 that protrudes laterally at the center. A die holder arm 143 is attached to the support shaft 139 via a coil spring 141. It is. The die holder 25 is stored at the tip of this die holder arm 143. A die holder storage section 145 is provided, and the die holder 25 is It is rotatably stored in the storage section 145.

[0025] The die holder 25 is a cylinder that is rotatably stored in the die holder storage section 145. It consists of a body part 147 and a flange member 149 incorporated into this cylindrical body part 147. A worm wheel 151 is provided on the end face of the flange portion of the flange member 149. Ru. In addition, a die 153 serving as a lower mold is provided at the center of the upper surface of this flange member 149. is attached, and the flange member 149 covers from the periphery of the die 153. A die holder cover 155 is attached. This die holder cover 155 has a The die holder rotation motor 157 provided on the die holder arm 143 is A notch 161 is formed into which the arm gear 159 is inserted.

[0026] The die holder 25 configured in this way is connected to the die of the die holder driving device 27. Y along the die holder moving support member 131 by the holder moving ball screw 33 The die holder rotation motor 157 of the die holder rotation device 163 is moved in the axial direction. and operates the worm wheel 151 via the worm gear 159 to rotate it. It will be done. Therefore, the punch holder arm 75 (see FIG. 1) and the die holder arm 143, punch holder movement motor 31 and die holder movement motor 3. 5, the punch holder 21 and the die holder 25 are synchronized at the same time. It can be moved the same distance in any direction. Also, the punch holder arm 75 is A ram cylinder moving device that engages a shot pin 57 with a ram cylinder mounting base 49 87, the ram cylinder 51 is moved together on the punch holder 21. Therefore, the punching process on the workpiece W can be performed at any position in the Y-axis direction. can also be done.

[0027] The punch 101 housed in the punch holder 21 is generally used. Out of 5 types from 1/2" to 4 1/2", there is no one with the maximum size 4 1/2". They are housed in groups of 4 to 5. The one shown in Figure 3 is 5 pieces of 1/2″ size, The one shown in Figure 4 accommodates four 4 1/4" size pieces. This enables a wide variety of punching processes. In addition, for this, the lower mold Needless to say, the die 153 is assembled in the same manner.

[0028] Each of these punches includes a pan having a pressure receiving part 104 inside the housing 105. If the outer diameter dimensions of the housing 105 are unified, Replacement and insertion into the holder is also possible.

[0029] Below, the punch holder 21 shown in Fig. 3 is attached to the punch press 1 shown in Fig. 1. We will explain the operation when

[0030] When the pressure receiving part 104 is set in alignment with the X-axis direction of the punch holder 21, the center Align the center punch position and the shot pin 57 on the punch holder arm 75 in a straight line. and move the ram cylinder mounting base 49 using this shot pin 57. Then, the striker 63 is located on either of the pressure receiving parts 104. There, I Position the workpiece W in the X-axis direction and perform the specified punching process, then move the shift cylinder If the striker 63 is shifted by the driver 67, the striker 63 will move to the next pressure receiving part 1. 04 and punching is performed. Y-axis direction inside punch holder 25 In order to punch the punches arranged in the punch holder rotation device 83, By rotating the punch holder 25 by 90 degrees by the motor 85, The pressure receiving part 104, which was placed in the Y-axis direction, is rotated in the X-axis direction, so the following is a Punching can be performed by the Leica shift device 61. At this time, die holder 2 5 may be rotated at the same time.

[0031] FIG. 6 shows another embodiment of the present invention. The punch press 171 of this embodiment is For the punch press 1 in the example, the punch holder 21 and die are used instead of the mold magazine 37. The holder 25 is attached to the endless chain 173 in two stages, upper and lower. One stage of the tubes 173 is circulated along the frame 5. Therefore, the real truth In the example, a ball screw for moving the punch holder and a ball screw for moving the die holder are used. The punch holder moving support portion of the guide side plate 69 of the upper frame 17 shown in FIG. Slide the supporter of the punch holder 21 onto the material 71 and move it to the lower side of the upper frame 17. Just send it. Be sure to install one shot pin 57 on this punch holder 21 side. Then, the ram cylinder mounting base 49 is engaged with the shot pin 57.

[0032] On the other hand, the die holder 25 engages with the die holder moving support member 131 shown in FIG. The supporter is moved on the upper side plate 127 of the lower frame 19. Therefore, punching processing can be performed.

[0033] As explained above, the punch presses 1 and 171 of this embodiment have multiple types of punch presses. A punch holder 21 provided with a punch 101 and a die holder provided with a plurality of types of dies 133. 25, move the ram cylinder mounting base 49 together with the pan holder 21, By shifting the striker 63 of the ram cylinder 51 in the X-axis direction, It has the characteristic that punching processing can be performed easily.

[0034] Note that the present invention is not limited to the embodiments described above, and may be modified as appropriate. Accordingly, other embodiments may also be implemented.

[0035]
