(54) METHOD FOR STAMPING PARTS FROM ROLL BELT

one

The invention relates to the field of metal forming and molset to be used in stamping of the detail of the roll tape.

A known method of stamping parts from a roll tape in a sequential multi-position stamp, separating the part from the tape at the last stamping position, at which the tape is filled, stamps a batch of parts and separates the ribbon that has not been worked out in the stamp from the batch.

The disadvantage of this method is that during the stamping of subsequent batches of parts, it is required to fill the belt into the stamp each time and carry it out successively through all the positions of the stamping. In most cases, this operation is performed manually and requires a significant investment of working time and skilled labor.

The purpose of the invention is to reduce the time required to reload the tape during the secondary and subsequent use of a stamp.

For this, according to the proposed method, the incomplete part of the tape after the completion of the stamping of a batch of parts is left in the stamp at the stamping positions, stored together with the stamp and connected to the roll, for example, by welding before stamping on the stamp the following

batch details.

FIG. 1 shows the proposed press equipped with a feeder, cutting tools and connecting devices; in fig. 2 - press, plan view.

The proposed method is carried out as follows.

Tape 1 by the feed mechanism 2 is automatically fed into the multi-position die 4 mounted on the press 3, where the last

the punching position is separated from the belt and the finished part is unloaded.

At the end of the stamping of a batch of parts, the cutting mechanism 5 is moved to the position shown in FIG. 2 dotted line, cut the tape 1 from the roll (not shown in the diagram) and return mechanism 5 to its original position.

In this case, the incomplete portion 6 of the tape is left in the stamp at the stamping positions

between its upper and lower blocks.

The stamp is removed from the press and the IT warehouse is sent to the stamp warehouse. At this time, the press can be used to stamp other parts. In the case of secondary and subsequent use of the stamp 4, it is re-installed on the press 3, the connecting mechanism 7 and the strap, into the position indicated in FIG. 2 by a dotted line, the end of the incomplete portion 6 of the tape is joined and connected to the end of the roll tape, for example, butt welding or brazing.

The connecting mechanism 7 is then returned to its original position (shown in Fig. 2 by solid lines), the press and the feed mechanism are turned on, and the next batch of parts is stamped. Thereafter, the operations are repeated in the same sequence.
