By the way, in press products for automobiles and press products for various devices, there are many post-processes for joining (assembling) by caulking, welding or the like after pressing.
In the conventional press working apparatus, in order to join and integrate the basic press-worked work by caulking or welding, the work must be temporarily stored in a stock pallet or the like, and the pallet is further transported to the joining apparatus. There must be.
For this reason, a place / space for stocking the pressed workpiece is required, and it takes time and labor to carry the workpiece. In addition, an external joining apparatus for joining such as caulking or welding has to be prepared separately.
And since the above-mentioned effort and time are taken, the speed and efficiency of the whole processing line will fall.

  Therefore, the present invention can perform a plurality of workpieces from a press process to a uniting / joining process without reducing the processing speed with a single press machine. An object of the present invention is to provide a press device that does not require a place and can save labor and increase work efficiency.

In FIG. 1, a first work 1 and a second work 2 are set in a basic processing unit 6 (on the most upstream side) of the press machine 3.
Then, as shown in FIG. 2, the upper die 4 is lowered as indicated by an arrow 36, and the basic work unit 6 performs basic press work in a state where the first work 1 and the second work 2 are arranged, and then the upper work As the mold 4 rises, the upper mold 6 a of the basic processing unit 6 rises in the direction opposite to the arrow 36.

Next, as shown in FIG. 3, the connected reciprocating body 18 of the connected work conveying means 19 operates inward as indicated by the arrow 21 (the connected reciprocating body 18 of the other connected work conveying means 19 not shown is also shown). At the same time, the first work 1 and the second work 2 on the lower die 6b of the basic processing unit 6 are gripped (gripped) by the grip unit K (as shown in FIG. 8B). .
Then, as shown in FIG. 4, the connected reciprocating body 18 is lifted as indicated by an arrow 22 and then moved as indicated by an arrow 23 so that the first work 1 and the second work 2 held by the grip unit K are adjacent to each other. It is transported to a position corresponding to the downstream basic processing unit 6.

Next, as shown in FIG. 5, the first work 1 and the second work 2 are conveyed onto the lower die 6 b of the basic processing unit 6 on the downstream side as the connected reciprocating body 18 is lowered as indicated by an arrow 24. And released from the grip unit K (see FIG. 8A).
Then, as shown in FIG. 6, the connected reciprocating body 18 operates outward as indicated by an arrow 25 (the other connected reciprocating body 18 (not shown) also operates outward at the same time). Moving to the upstream side, the grip unit K returns to the position corresponding to the original basic processing unit 6 as shown in FIG.
In accordance with the operations of the arrows 21 to 26 of the coupled reciprocating body 18 as described above, the grip unit K...

The first and second grips G ₁ and G _{2 are} released (see FIG. 8A).
At this time, the first work 1 is lowered until it comes into contact with the second work 2 (due to gravity).

Then, as shown in FIG. 6, the workpiece transfer means 9 corresponds to the most downstream unit 16 as the connected reciprocating body 18 moves outward as indicated by an arrow 25 and then moves upstream as indicated by an arrow 26. Return to the position to perform (see FIG. 2).
During the movement indicated by the arrow 26, the first and second screw shafts 31 and 32 (see FIG. 7) rotate in the opposite direction to the arrow 33 by the operation of the motor 13, and the first and second grips G ₁ and G ₂ is going away.
In FIG. 2, the upper mold 4 is lowered as indicated by an arrow 36, and the first work 1 and the second work 2 that are vertically stacked are crimped by the crimping processing unit 7.
As described above, the first work 1 and the second work 2 are sequentially conveyed from the most downstream unit 16 to the caulking processing unit 7.

Then, the crimped and combined work (as shown in FIGS. 9 and 10) is carried to the stock field by human power or a robot arm (not shown).
As described above, the first workpiece 1 and the second workpiece 2 are the basic processing units in accordance with the reciprocation of the connected reciprocating bodies 18 and 18 provided on both sides of the plurality of units in one press machine 3.

As described above, in the press working of the present invention, the first press 1 and the second work 2 are arranged in one press machine 3 and the basic press work is performed in a plurality of press processes. The one work 1 and the second work 2 are conveyed to the final process while being vertically stacked in one press machine 3, and the first work 1 and the second work 2 that are overlapped in the final process. Since a single press machine 3 combines them by caulking, a single press machine 3 can perform caulking processing on a plurality of workpieces simultaneously with basic press processing. There is no need to prepare a separate external joining device, etc., and there is no need to stock the workpiece after pressing, so there is no need to stock it. Can reduce It is possible to save humanized.
And since processing until a workpiece | work is integrated progresses, without reducing speed, labor saving, a raise of work efficiency, and working time reduction can be aimed at.
