SU1225654A1 - Die for manufacturing parts from rolled stock - Google Patents

Description

The invention relates to the processing of metals by pressure and can be used in the manufacture of parts by cutting.

The purpose of the invention is to increase the accuracy of manufacturing the part by providing transverse fixation of the rolled metal in the die.

FIG. 1 shows the proposed stamp, cross section, in the initial position; in fig. 2 shows section A-A in FIG. one; on firm. 3 - stamp cross section in an intermediate position; FIG. A is a section BB in FIG. 3

The stamp contains an upper plate 1 with a knife 2 and punches 3 fixed on it. A puller 5 is fixed on the bottom plate 4, in which guides are made for the U-shaped carriage 6. The clamp 7 is fixed on the U-shaped carriage 6, and the ejector 8 is made console and also mounted on the carriage 6. An abutment 9 for the longitudinal base of the part produced in the die and the abutments 10 for its transverse base are mounted in the lower part of the punch.

A gear block 11 is also installed in the lower plate of the stamp. with U-shaped carriage 6.

The carriage feed mechanism 16 (for example, a strip) is hinged by means of an axis 17 and is spring-loaded to the top by a spring 18, because the lower plane of the strip in the feed mechanism is located above the part 19 located in the die.

The stamp works as follows. In the initial position, the strip is fed up to the stop 9 in the stamp (Fig. 2), the upper part of the stamp is located in the extreme upper position, U-shape

on the carriage 6 occupies the leftmost position (Fig. 1), and the ejector 8 is located under the strip.

During the course of the upper part of the stamp down the slats 12 and 15 and through the gear block 11, the carriage 6 is moved to the right and the ejector 8 leaves the strip. The knife 2 acts on the strip and lowers it onto the stamp mirror, tilting the feed mechanism 16 around the axis 17. Simultaneously moving together with the carriage 6, the clamp 7 presses the strip against the stops 10 and stops. Upon further movement of the upper part of the stamp downward, the spring 14 is compressed, the knife 2 cuts off part 19 from the strip, and the punches 3 pierce holes in it.

During the course of the upper part of the stamp, the knife 2 moves away from the strip and it restores its position under the influence of the spring 18. The tool 19 is removed from the punches by the puller 5 and falls onto the stamp mirror. After selecting the gap between the top plate 1 and the ring. 13 rail 12 through the gear unit 11 and the rail 15 moves the carriage 6 to the left, and the ejector 8 displaces the part

Plate 4 stamp (Fig. 3).

Simultaneously with the ejection of the part 19, the strip starts to be delivered, carried out in the plane located above the parts 19 and the ejector 8. By the time the upper part of the die arrives in the extreme upper position, the part 19 is completely ejected. stamp, and the band is fed until it stops 9. Next, the operation cycle of the stamp Repeats without stopping.

Thus, the proposed die design, along with pushing the part from the die in the transverse direction, ensures its pressing against the longitudinal and transverse base stops, which increases the accuracy of the part manufacture.
