Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a forging press equipped with a transfer feed device for transferring outer material generated between press-operated dies.

In a conventional forging press equipped with a transfer feed device, the outer shell is gripped by two-pronged claws arranged opposite each other and fed sequentially, so when transferring the outer shell whose shape in the horizontal direction is not specified, it is possible to transfer the outer shell reliably. There were many inconveniences such as not being grasped and falling off during transportation.

A claw device that scoops out the outer edges could be considered as a means to improve this problem, but using scooping claws has the disadvantage that the inertia during transportation causes the product to shift relative to the claw, making it difficult to carry out the next process smoothly. there were.

The present invention was made to eliminate the above-mentioned drawbacks, and includes a forging press equipped with a transfer feed device that can scoop the outer material and clamp it from the top of the material at the same time to reliably feed the outer material sequentially. This is what we are trying to provide.

The embodiment will be explained below with reference to the drawings. In the drawing, 1 is a set of two feed bars each having a plurality of rake claws 2 on opposite sides, both ends of which are connected to a drive device 3.4. The structure is such that the rake claw 2 is moved in a three-dimensional direction along a locus shown in FIG. 3 by the operation of the drive devices 3 and 4.

Reference numerals 5 and 5' designate a mold 5'' which is a terminal mold, and 6 a press body frame.

A holder 9 is movably attached to the feed bar 1 and has a rake claw 2 and a side-view type rotary clamper 8 for clamping the upper surface of the outer material 7 placed on the claw 2 at the end thereof. ing.

10 is a spring that keeps the clamper 8 open when it is not in operation.

Reference numeral 11 denotes a spring that elastically urges the holder 9 toward the mold side, and its spring force is greater than that of the spring 10.

Next, the operation of the transfer feed device of the present invention will be explained. By the scooping action of the feed bar 1, the scooping claw 2 is inserted into the lower surface of the outer material 7 on the lower end mold 5''.

As a result of this insertion operation, the end of the outer pawl material comes into contact with the protrusion on the rake side of the clamper 8, and the clamper 8 rotates downward against the spring 10, and the clamper 8 cooperates with the rake pawl 2 to to clamp.

Thereafter, the outer material is scooped out from the end mold 5'' by the lifting operation of the feed bar 1, and then transported to the next process location by the subsequent feeding operation of the feed bar 1.

When the next process is reached, the outer material is placed on the floor by the reverse lifting motion of the feed bar 1, and then the rake claw 2 is pulled out by the separating motion, but at the same time, the clamper 8 is
rotates in the opposite direction and unclamps.

Therefore, the outer material can be reliably transferred to a predetermined position in a constant posture.

Furthermore, as shown in FIGS. 1 and 4 to 6, for example, a holder 9 equipped with a product gripping claw 12 and a scooping claw 2 with a clamper 8 is mounted on a rack shaft 13 that is not linked to the feed operation of the feed bar 1. If the ring-shaped product 14 and the outer barrier are rotated and discharged from the mold 5'' at the end, the outer barrier hits the product 14 from behind due to inertia, which is the so-called "back strike", which can be prevented. 14 and the outer barrier can be reliably dropped and discharged by the respective shoes 16 and 17.

As described above, according to the present invention, the outer burr can be scooped out from above the end mold while applying a clamping force from the upper surface of the burr, and can be reliably conveyed to the next process.
