When the 2a reciprocates in the longitudinal direction, the clamp portion 23 swings as shown by arrows I and J in FIG. 6, and when the clamp portion 23 swings as shown by the arrow J, the pressing piece 25 of the clamp portion 23 moves the pressing piece 25 of the frame body. 21
The work W can be inserted between the pressing piece 25 and the frame body 21, and when the workpiece W is swung as indicated by the arrow I, the space between the pressing piece 25 and the frame body 21 can be increased. It is possible to hold the work W that has entered the.

The clamp mechanism 10 includes a cylinder 20.
If the piston rod 20a of FIG.
As shown in FIG.

Therefore, the clan attached to the main bar 2
Each of the push mechanisms 10 has a main bar 2 as shown in FIG.
Constant feed stroke of arrow E in a separate arrow G and reciprocation of F, it is possible to reciprocate in the longitudinal direction of the small sub-feed stroke of H, also a certain lateral main inverter 2 (arrow The reciprocating movement of the lateral arrows K and L can be performed separately from the clamp stroke in the A and B directions).

The sub-unit 3 having the work clamp mechanism 10 is detachably attached to the main bar 2. That is, the legs 19 of the guide member 12 are detachably attached to the main bar 2 via attachments such as bolts.
Therefore, the small sub feed stroke and the small sub clamp stroke can be freely changed by changing the entire subunit 3.

Next, a method of pressing the work W by using the work transfer device configured as described above will be described.

That is, as shown in FIG. 8, the arrangement pitch between the workpiece mounting stage 8 and the upstream die 1 is set to P ₁ .
The arrangement pitch between the upstream mold 1 and the downstream mold 1 is set to P ₂
Then, the case where the stage 8, the molds 1, 1 and the conveyor are arranged with the arrangement pitch of the downstream mold 1 and the work W transport conveyor being P ₃ will be described.

Further, in FIG. 8, reference numeral 26 is a cutter device for cutting a long work forming material 28 wound around a drum 27 to form a work W having a predetermined size.

The work W cut and formed by the cutter device 26 is first conveyed to the stage 8.

When the work W is conveyed to the stage 8, the main bar 2 moves laterally as shown by arrow A as shown in FIG. 10, and the clamp mechanism 10 moves laterally as shown by arrow K, The clamp mechanism 10 holds the work W on the stage 8.

Next, main bars 2 is increased as indicated by arrow C, after separating the workpiece W from the stage 8, the main bar 2 advances in the longitudinal direction as indicated by the arrow E, the longitudinal direction
Countercurrent forward backward member 9 is advanced in the longitudinal direction as indicated by arrow G.

As a result, the work W is conveyed to the die 1 on the upstream side, and then the main bar 2 descends as shown by the arrow D, and the gripping of the work W by the clamp mechanism 10 is released. Set in mold 1.

Next, when the main bar 2 moves laterally as indicated by arrow B and the clamp mechanism 10 moves laterally,
The lateral reciprocating mechanism 20 allows the clamp mechanism 10 to
Further , the clamp mechanism 10 is moved laterally as indicated by an arrow L.
But the work W is extended and the mold 1 is separated.

Thereafter, the main bar 2 retracts in the longitudinal direction as indicated by the arrow F, and the longitudinal reciprocating member 9 retracts in the longitudinal direction as indicated by the arrow H to return to the original state.

At this time (when the clamp mechanism 10 is separated from the work W and the subunit 3 is retracted in the longitudinal direction), the upper die 1a is lowered by the press machine, and a molding process (for example, drawing) by the die 1 is performed. Processing) is performed.

As shown in FIG. 10, the workpiece W machined by the upstream die 1 is swung by the main bar 2, the subunit 3, and the clamp mechanism 10 of the subunit 3. While being discharged from the mold 1, it is conveyed to the next mold 1.

The work W conveyed to the next mold 1 is subjected to molding processing (for example, edging processing) in this mold 1.

The work W processed by the die 1 on the downstream side is similarly discharged from the die 1 and conveyed to the conveyor device.

Therefore, work transfer from the stage 8 to the upstream mold 1, work transfer from the upstream mold 1 to the downstream mold 1, work transfer from the downstream mold 1 to the conveyor device. Can be done at the same time.

Moreover, as shown in FIG. 8, when the constant feed stroke is P, the small sub-feed stroke of the most upstream subunit 3 is P _4, and the small sub-feed stroke of the next subunit 3 is P ₅ and the small sub-feed stroke of the next subunit 3 as P ₆ , P ₁ = P + P ₄ , P ₂ = P + P ₅ , P ₃ =
Since P + P ₆ is set, each work W can be sequentially supplied / discharged in accordance with the arrangement pitch of the stage 8, the molds 1, 1 and the conveyor device.

[0054] Further, as shown in FIG. 9, 'if it is, the small sub-clamping stroke of the clamping mechanism 10 _{P 2'} constant clamping stroke P _as, P 1 '(P'
Since the clamp mechanism 10 is set to move in the lateral direction with a stroke of + P ₂ ′), the total amount of lateral movement of the clamp mechanism 10 can be adjusted, and the clamp mechanism 10 can be adjusted to correspond to the lateral length of the work W. It is possible to move the clamp mechanism 10 by moving.

In other words, each work W is securely clamped by the clamp mechanism 1.
It can be clamped at zero.

The present invention is not limited to the above-described embodiments, and the design can be freely changed without departing from the gist of the present invention. For example, the number, size, shape, etc. of the dies 1 arranged in a row can be changed. In addition to being able to freely change the arrangement pitch, the small sub-feed stroke and small sub-clamp stroke can be freely changed according to them, and the small sub-stroke can be changed. The feed stroke amount and the small sub-clamp stroke amount may not be constant and may be changed. Of course, the constant feed stroke or clamp stroke is not limited to the pitch shown in the figure.

Further, in the embodiment, the small sub-clamp stroke pitches of the work clamp mechanism 10 of each unit 3 are the same, but of course they may be different.

Furthermore, in the embodiment, when the main bar 2 moves (that is, moves forward) in the direction of arrow E, the subunit 3 similarly advances as indicated by arrow G, and the main bar 2 moves in the direction of arrow F.
Similarly, when the main bar 2 moves forward (that is, moves backward), the sub-unit 3 moves backward when the main bar 2 moves forward. It is also free to set the subunit 3 to move forward when is moved backward.

Similarly, also in the clamp mechanism 10, when the main bar 2 moves in the direction of arrow A, it moves as shown by arrow L, and when the main bar 2 moves in the direction of arrow B, it moves as shown by arrow K. It is also free to set to do. Also,
The number of the clamp mechanisms 10 does not have to be two per one unit 3, and the number can be freely increased or decreased.
