(Ii) Processing standards are always required for processing, but since the processing systems are separate and independent, it is necessary to match the processing standards of the previous process with those of the subsequent process. It is complicated and causes a reduction in dimensional accuracy of the final product due to a mismatch in the processing standard.

[0008] The present invention solves the above-mentioned problems in the prior art, and provides a multi-tasking machine capable of high-mix low-volume production, ensuring high dimensional accuracy, and performing complex precision machining at low cost. The task is to provide.

In the above-mentioned forging and half blanking, the bottom dead center position of each punch is set in advance in the mode shown in FIG. 5, and a pair of punches and dies corresponding to each processing step is set. It only has to be selected and activated. These controls can be easily performed by the computer 60 as described with reference to FIG.

Next, in the processing step (d), the outer edge of the second flat portion 92 is cut into a cylindrical surface having a diameter of 0.9 mm. In this case, for example, the ball end mill 53 having an outer diameter of 1 mm and a radius of 0.5 mm is rotated at a rotation speed of 15,000 rpm. That is, in FIG. 1, the workpiece 9 is inserted into the cutting device 4 by the material support device 8, the support means 25 in FIG. 2 is rotated, and the cutting process is performed while the workpiece 9 is fed in the longitudinal direction.

Is detachably mounted.

First, a workpiece (not shown) is inserted between the punch 33 and the die 34 (if necessary, by the first forging device 2 shown in FIG. 2 for example, flattening as shown in FIG. 9). After forming the part 95), the punch 33 is lowered to perform punching. This punching process forms a square hole 98 as shown in FIG.

Next, in FIG. 10 (a), the punch 33 and the die 43 are rotated by 22.5 ° in the direction of the arrow while holding the workpiece in the above-mentioned position, and the punching and punching are performed in the hole 98. After processing, punch 33 and die 4
3 is rotated 45 ° in the direction of the arrow to perform the same overlapping punching. By such processing, a star-shaped hole 99 having 16 concave portions and convex portions as shown in FIG.
Can be molded.

In this case, the punch 33 and the die 43
As described with reference to FIG. 3, the concave portions and the convex portions are arranged at equal intervals in the circumferential direction because they are formed so as to be synchronously rotated and indexable so that relative rotation does not occur between them. The hole 99 can be formed with high dimensional accuracy because it is formed by the same punch 33 and die 43.

FIG. 11 shows a fourth embodiment according to the present invention.
It is a principal part enlarged plan view which shows the processing example of (a)-(c).
Indicate the respective processing steps, and the same parts are indicated by the same reference numerals as in FIG. In this case, the work material 9 is the same as that in the above-described working example, a dummy plate material 69 made of an aluminum plate is used on both sides of the work material 9, and the cross-sectional shape is a square shape having a side of 1 mm. Punching was performed using a punch and a die. As the processing device, a second forging device 3 shown in FIGS. 1 and 3 was used.

That is, in a state where each side of each cross section of the punch and the die is positioned so as to form 45 ° with the longitudinal direction of the workpiece 9, the punch (not shown) is operated to perform the first punching. Then, the workpiece 9 is fed in a predetermined pitch Y direction (forward direction) to perform a second punching process. In this case, although the center of the first crocodile portion 90a is off the center of the workpiece 9, the dummy plate 69 is sandwiched on both sides of the workpiece 9, so that the punch escapes in the left-right direction. Can be prevented.

Next, in the processing step (b), the second crocodile portion 90b is formed. That is, each side of each cross section of the punch and the die is 30 ° with respect to the longitudinal direction of the workpiece 9.
The punch and the die are positioned in such a manner that they are turned, for example, 15 ° clockwise so as to form an angle of 60 °, and the workpiece 9 is fed at a predetermined pitch in the longitudinal direction, and the punching is performed as described above. .

Further, in the processing step (c), the punch and the die are further rotated clockwise by 15 ° so that each side of each cross section of the punch and the die is 15 ° with respect to the longitudinal direction of the workpiece 9. The third crocodile mouth portion 90c is formed by punching at an angle of 75 °. By performing such a series of punching, a product having a plurality of crocodile portions 90a, 90b, 90c having different inclination angles can be formed.

In the above embodiment of the present invention, the first
Although the example in which the forging device and the second forging device are separately and independently provided has been described, at least one pair of punches and dies constituting the first forging device are formed so as to be synchronously rotated and indexable. The second forging device may be omitted. Further, the plurality of pairs of punches and dies may be provided not along the circumferential direction but along the feed direction of the material supporting device. In short, the plurality of pairs of punches and dies can be moved synchronously. It is sufficient if only the selected punch is operated by the striker.

The above-mentioned punches and dies need only be capable of so-called plastic working such as shearing, bending, forging or drawing. Further, a plurality of rotary cutting means constituting the cutting apparatus may be provided, for example, in the circumferential direction of a disk-shaped holder, and may be a so-called turret type. In short, the material to be processed is selected from the above by the material supporting device. What is necessary is just to be able to insert and remove the rotary cutting means. These rotary cutting means can perform not only ordinary internal and external surface turning but also processing of a flat surface or a curved surface by an end mill, and can also process a thread-like product by using the feed control in a material supporting device.

The drive system of each component device is most commonly an electric system represented by a rotary motor, but may be a hydraulic system such as a hydraulic system or a pneumatic system. Any of the molds can be used, and they can be computer controlled.

Further, as a material to be processed, a wire having a geometric shape other than a wire having a circular cross section can be naturally applied, and a short bar or a strip which is cut to a predetermined length can be used. This is also applicable as long as it can be attached and detached and supported by using a robot or the like.
