A head frame 30 is extended above, and a hydraulic cylinder 32 is installed vertically as a press drive means on the upper plate 28 fixed to the head frame 30, and a press head 33 is attached to the tip of the ram to pass through the upper plate 28 and press the press bed 27. It hangs above. 34 is a waste removal hole of the press bed, 34' is a waste box, and 35 is a stopper. 20' is each guide rail 20 mentioned above.
Tapered ends are formed at the front end of the U-shaped guide groove of . Figure 5).

The profile handling mechanism C grips the profile m with chucks 36, 36 in the front-rear direction, and in this state performs operations such as moving the profile in the front-rear direction and rotating the profile by a desired angle about the axis of the profile. .

This example is further equipped with a mechanism that adjusts the positions of the press mold storage mechanism A and the press drive mechanism B in the longitudinal direction according to the length of the shape m. In FIGS. 1 and 3, opposing guide grooves 2, 2 having a U-shaped cross section are formed on both left and right sides of the base frame 1, and guide grooves 2, 2 are formed in both the left and right sides of the bottom of the frame 3.

A male threaded rod 38 connected to the output shaft of the motor is rotatably supported by bearings 38 and 39 in the longitudinal direction, and a female threaded block 40 protruding from the lower surface of the frame 3 is screwed into the male threaded rod 38. ing. When the male threaded rod 38 is rotated by the rotation of the motor 37 and the female threaded block 40 screwed therewith is moved, the frame 3 is moved back and forth along the guide grooves 2, 2.

The operation of this device will be explained next along with an example of its use. As an example of use, first, a plurality of types of press molds, for example, four types of press molds necessary for a plurality of types of press working of one type of shape material m, are set on one movable shelf board 43, and similarly two other movable Four types of press dies for other types of shapes are also set on the shelf boards 43, 43, respectively. In this way, three movable shelf boards 43 are each set with four types of press dies 5 for three types of shapes.
are respectively set on the fixed shelves 41 in the storage case 6.

In operation, first, by operating the handling mechanism C, the end of the profile m is inserted between the press head 27 and the press head 33 of the press drive mechanism B as shown by the chain lines in FIGS.

Next, the index motor 18 is started to rotate the male screw rods 56, 56, and the storage case 6 is moved up or down a desired distance to place the desired press mold 5.
The movable shelf board 43 on which is placed is moved to the height of the transfer position P. The shelf plate 43 stopped at that height engages its rack 48 with the pinion 61.

Next, the transfer drive hydraulic cylinder 22 is driven forward to advance the locking portion 24 at the tip of the ram onto the movement track of the receiver 26 between the two intermediate press dies 5, 5, and then the index motor 60 is moved forward. Upon starting, the transfer position P is transferred via the pinion 61 and the rack 48.
The shelf board 43 at a height of is moved to the left or right, and the desired press mold 5 on the shelf board 43 is moved to the transfer position P. The press die 5 stopped at the transfer position P has its receiving portion 26 fitted into the locking portion 24 .

Next, the ram 23 is advanced forward by the advancement drive of the transfer drive hydraulic cylinder 22, thereby moving the press mold 5 at the transfer position P to the guide rail 2.
0, 20 on the shelf board 43 and place the guide rail 3 on the press bed 27 of the press drive mechanism B.
1, 31. The press die 5 comes into contact with the stopper 35 and reaches a predetermined press position.

Then, in this state, the press head 3 is moved forward by driving the press drive hydraulic cylinder 32.
3 is lowered to push down the upper plate 10 of the press mold 5, whereby a predetermined press work is performed on the profile m between the upper mold 12 and the lower mold 13.

When the machining is completed, the press head 33 is raised, and the ram 23 is moved backward by the backward drive of the transfer hydraulic cylinder 22, whereby the used press mold 5 is moved from above the bed 27 to the original shelf board 4.
3 on top of the guide rails 31, 31 and then 20, 20
Pull back along. The press die 5 has a stopper 21
and is stored in a predetermined storage position.

After the first pressing, if necessary, the shape material m is rotated by a desired angle by operating the handling mechanism C, and then the movable shelf board 43 used in the first pressing is moved in the left and right direction by the drive of the motor 60, so that the shelf The next desired press die 5 on the plate 43 is moved to the transfer position P. The locking portion 25 of the next press mold 5 that has reached the transfer position P is locked to the receiving portion 26 thereof. Next, a second press process is performed in the same manner as the first process, and thereafter, four types of press processes, such as a third and fourth press process, are performed in the same manner.

Shape m that has completed the specified press processing is marked 3.
6 and 36, replace it with a new same type of profile m, and repeat the same four types of press working.

Next, when applying the other four types of press working to another type of shape material m, first, the above-mentioned locking part 25 is connected to the receiving part 26.
The shelf board 43 is slightly moved left and right by the drive of the motor 60 so as to take a state in which it is detached from the lock, and then the locking part 24 is retreated to its original position by the backward drive of the hydraulic cylinder 22. The chucks 36, 36 are made to grip a new shape m of another type, and then the storage case 6 is moved vertically in the same way as described above, and the movable press die necessary for pressing the shape m is placed thereon. The shelf board 43 is moved to the height of the transfer position P, and four types of press working are performed using four new types of press molds 5 in the same manner as described above.

In the above usage example, if the type of shape material to be processed changes to something different from the three types in the above example, the multiple types of press molds required for it are changed to the movable shelf board 4.
All you have to do is replace all 3.

In addition, all the press dies 5 necessary for a plurality of planned workpiece materials are stored on each movable shelf board 43 of the storage case 6, and their lengths,
By setting the necessary press molds in a microcomputer or the like, automatic processing of a wide variety of materials in small lots becomes easy.

As another example of the use of this apparatus, a plurality of apparatuses of the present invention may be arranged in parallel along a processing line to perform a plurality of types of press working on each of a plurality of types of workpiece materials. In this case, each of the apparatuses may perform one type of press processing on each workpiece material, and a plurality of apparatuses may perform desired plurality of types of processing on each workpiece material.

As another embodiment of this device, the left and right length of the storage case 6 in the above example is increased appropriately, and each movable shelf board 43
There is also an example in which the press molds 5 can be moved left and right within the storage case 6 to match the left and right positions of the respective press molds 5 with the transfer position P.

In either example, in order to stop each press mold 5 at a predetermined storage position on the shelf board 43, as an example, a stop ball 62, which is constantly urged by a spring 63, is attached to the shelf board 43 as shown in FIG. It is preferable that the ball 62 is provided so that the ball 62 is elastically engaged with a recessed hole 64 provided in the lower plate 8 of the press mold 5.

According to the device for performing multiple types of press working of the present invention, multiple types of press dies can be stored in the storage case, thereby making it possible to perform multiple types of press working. The press is capable of automatically and accurately taking out a desired press die from many types of press dies, transferring it to a press drive mechanism, and automatically and accurately returning it to its original storage position. This has the advantage that it can be effectively used for processing automation and line formation.
