 Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. First, the overall structure of the turret punch press will be described with reference to FIGS. 1 and 2. A frame 3 is integrally formed on a base 1 in a gate shape. Upper and lower turrets 5 and 7 are rotatably arranged on one side inside the frame 3. A large number of metal molds 9 are attached to the upper and lower turrets 5 and 7 in a pair. The upper and lower turrets 5 and 7 are synchronously rotated by a turret drive motor 11, so that a desired die 9 can be positioned at a position directly below the striker 13 which is a processing position.

In FIG. 1, the carriage 23 is reciprocally driven in the Y-axis direction, which is the front-rear direction. A clamp 25 is attached to the carriage 23, and the work W is gripped by the clamp 25.

In order to support the work W, as shown in detail in FIG. 2, a fixing table 27 is provided in the center of the inside of the frame 3 so as to be fixed on the base 1, and on both sides of the fixing table 27. A movable table 29 that reciprocates in the X-axis direction is also provided. A repositioning table 31 is provided near the turrets 5 and 7.

In the turret punch press having such a configuration, the upper and lower turrets 5 and 7 are fitted with a large number of a pair of upper and lower molds 9 properly combined, and the mold 9 having a shape to be formed at the processing position P. In order to index the position directly below a certain striker 13, the turret drive motor 11 is rotated by a predetermined angle, whereby the upper and lower turrets 5, 7 are rotated by a predetermined angle, and the desired die 9 is positioned at the processing position P. Further, the work W is gripped by the clamp 25 and the base drive motor 17 is driven to move the carriage base 19 in the X-axis direction, and the carriage drive motor 21 is driven with respect to the carriage base 19 to move the carriage 23. The clamp 25 is moved in the Y-axis direction, and the XY two-dimensional movement of the clamp 25 positions the portion of the workpiece W to be machined at the machining position P. After that, the striker 13 is driven by a ram mechanism (not shown) to press the head portion of the upper mold, thereby punching a desired shape between the upper and lower molds. In the case of the punch / laser composite processing machine, a predetermined portion of the work W is positioned at the position of the laser processing head 14 and laser processing is performed.

In such a general turret punch press, the characteristic part of the embodiment of the invention of claim 1 will be described with reference to FIG. 3, in which the index device 35 is vertically moved through the bearing 33 in the upper turret 5. It is attached so that it penetrates through, and the press bending die 37 necessary for bending of a predetermined shape is inserted into the index device 35, and it can slide up and down but rotate with respect to the upper index device 35. It is guided by the key 39 not to do so. Worm teeth 41 are engraved on the upper circumference of the upper index device 35, and the worm teeth 41 are meshed with the worm gear 43. The rotation of the worm gear 43 causes the upper index device 35 to rotate by a desired angle. Then, the pressing and bending die 37 inside is co-rotated by the key 39 to be positioned in a predetermined direction as shown in FIG.

On the other hand, a lower index device 47 is attached to the lower turret 7 via a bearing 45 so as to rotate together with the upper index device 35 of the upper turret 5 by appropriate means. Inside the lower index device 47, a plurality of selection cylinders 49 that operate in the horizontal direction are arranged, and the inclined piston heads 51 of the respective selection cylinders 49 come into contact with the lower parts, and the piston heads 51 move forward and backward. A plurality of backup blocks 53 are installed in the lower index device 47 so as to move up and down.

A lifter 57 biased upward by a spring 55 is provided on the upper part of the lower index device 47, and the work W is pushed up from the upper surface of the lower index device 47 by the lifter 57.

Next, a bending operation by the turret punch press having the above structure will be described. First, in order to punch a semi-finished product 63 having a predetermined shape with respect to the work W while leaving the micro joint 61 as shown in FIG. 6, the micro-joint portion 61 is provided in predetermined mounting holes of the upper and lower turrets 5, 7. A mold 9 having a shape capable of leaving is placed, and the upper and lower turrets 5 and 7 are rotated at a predetermined angle to be positioned at the processing position P. Further, the work W is gripped by the clamp 25, and the carriage device 15 is XY two-dimensionally moved and operated so that a predetermined processing portion comes to the processing position P.

When the die 9 having the predetermined shape and the processing portion of the work W are positioned at the processing position P in this way, the striker 13 is then driven to press the head portion of the upper die to predetermined the work W 1. Punch the part to be processed. In this case, since a die capable of punching leaving the micro joint 61 is used, a semi-finished product 63 is obtained which is slightly connected to the work W main body side by the micro joint 61 as shown in FIG. To be

Subsequently, the semi-finished product 63 is to be bent along the bending line 65. The upper and lower turrets 5 and 7 are rotated to be preliminarily attached to the upper and lower turrets 5 and 7, respectively. The upper and lower indexing devices 35 and 47 are positioned at the processing position P. Then, the workpiece W is repositioned by the carriage device 15 in order to align the bending line portion of the bending press die 37 with the position of the bending line 65, and the index devices 35 and 47 are rotated by a required angle. For example, in FIG. 6, the bending lines a and b parallel to the X axis in the semifinished product 63 shown by A and the bending lines e, f and g parallel to the X axis in the semifinished product 63 of B are If it is not necessary to rotate the index devices 35 and 47, the folding lines c and d parallel to the Y axis in the A semifinished product 63 and the Y axis of the B semifinished product 63 are parallel to this. For the bending lines g and h, the indexing devices 35 and 47 are rotated by 90 degrees. Further, for the oblique bending line k in the B semifinished product 63, the indexing devices 35 and 47 are rotated by 45 degrees.

Further, according to the length of each of the bending lines a, b, c, ..., the number of the backup blocks 53 is set to be three as shown in FIG. 4, for example. The selection cylinder 49 is operated to push out the piston head 51, whereby the three backup blocks 53 are set so that their upper ends project above the upper surface of the lower index device 47.

After that, the striker 13 is lowered by a conventionally known method, and the head portion of the bending press die 37 attached to the upper index device 35 is pressed. As a result, the bending press die 37 is lowered until its head portion comes into contact with the upper end surface of the index device 35.

In this manner, the angle adjustment by the rotation of the index devices 35 and 47 and the position adjustment of the processing portion by the carriage device 15 bends an arbitrary edge portion of the semi-finished product 63 from the bending line, and finally, The last remaining micro joint 61 is separated from the work W and bent, so that punching and bending can be performed continuously by one processing machine, and the flat work W is bent together with punching. You will be able to take out the finished product.

In FIG. 6, in the semi-finished product 63 of A, m is provided in parallel with the bending line a, and it is necessary to bend this end portion by 2 times, but the working mode in this case is As shown in FIGS. 3 and 4, first, bending is performed from the outer bending line a, and the carriage device 15 is actuated to move the work W slightly in the Y-axis direction to move the bending line m. Repositioning so that the bending edge of the bending press die 37 of the upper index device 35 is positioned at the position, and then the striker 13 is driven to bend the bending press die 37 from the bending line m. It will be processed. By this two-step bending process, the bending part 65 having a C-shaped cross section is obtained.

In the above embodiment, in the turret punch press, a punching die is prepared so that punching can be performed while leaving the micro joint, and after punching by this, the micro joint remains connected to the work side. The case where the semi-finished product was subjected to bending from a predetermined bending line portion to cut the micro-joint and to perform the bending process to obtain the final product was explained. However, the present invention is not limited to the above-mentioned embodiment, and can be applied to a punch / laser combined machining machine. In that case, the laser machining head 14 slightly connects the workpiece to the workpiece side with a micro joint. First, laser cutting of a predetermined shape is performed so that the laser cutting portion is bent by a suitable pressing bending die attached to the turret indexing device as in the above embodiment. You can also do it.
