SU1454564A1 - Die for forming parts from tubular billets - Google Patents

Abstract

The invention relates to a technique for metal forming, namely, dies for stamping parts from tubular blanks. The purpose of the invention is to expand technological capabilities and reduce the cost of manufactured products. The stamp has a calibrating rod consisting of two parts, one of which is movably mounted on the upper half, and the other is rigidly fixed on the lower half of the stamp. An annular ejector is provided for pushing out products. The design of the stamp allows reducing the required stroke of the ejector and increasing the clearance between the upper and lower halves of the stamp. This makes it possible to load higher blanks. 2 Il.

The invention relates to pressure treatment, in particular, to the design of dies for stamping parts from tubular blanks.

The aim of the invention is to expand the technological capabilities and reduce the cost of manufactured products.

FIG. 1 shows a stamp for stamping parts from tubular blanks at the beginning (left) and at the end (right) of deformation of the workpiece; in fig. 2 - stamp at the moment of the beginning of force contact between the ends of the parts of the gage rod (left) and at the moment of the beginning of deformation of the tubular powder billet (right).

The stamp for hot stamping of details from tubular blanks consists of the upper 1 and lower 2 halves,. rigidly fixed in the lower half of part 2 of 3. calibrating rod and

the upper part 4 of the gauge rod installed in the upper half 1 with the possibility of relative axial movement and a spring-loaded elastic element 5 dp of providing force contact between the ends of the parts 3 and 4 of the gage rod during the stamping process, as well as the ring ejector 6 fixed to

15 mobile half stamp. Position 9 marked tubular billet, and position 10 - forging.

The stamp works as follows. In the upper position of the upper half of the 1 punch, the upper part 4 of the gage rod is pressed by the elastic element 5 and is located at the extreme bottom; ate

In this position, relative to this half of the stamp, at this moment the ring ejector 6, together with the beam 7, which hangs on the arms 8 connected to the upper half of the stamp 1, is in the extreme upper position relative to the lower half; we are 2 stamps (Fig. 1) .

At the end of the annular ejector 6, a tubular billet 9 is installed and stamped. During the course of the upper half of the punch down, the annular ejector 6, together with the rocker 7, is lowered all the way down into the sub-stamping plate of the lower half of the punch. In this case, the workpiece 9, moving together with the ring ejector 6, goes to the bottom part 3.

the calibrating rod returns to its original position under the action of the elastic element 5. Then, after the heads are hooked, the claws 8 with the protrusions of the upper half of the punch rod 8 move the yoke 7 and the ring ejector 6 upwardly relative to the lower half of the 2 punch and the forging 10 is pushed out of the lower half of the stamp and eat it from the bottom of the gage rod, after which the cycle repeats.

Such a punch design allows to reduce the required stroke of the ejector body and increase the clearance between the upper and lower halves of the punch, which provides the ability to load

I feel the cavity of the lower half of the 2 punch (Fig. 2). The upper part 4 of the gauge rod, moving down along with the upper half of the stamp 1, enters the opening of the tubular billet 9 until it stops at the end of the lower part 3 of the gage rod, part 4 of the gage rod stands and compresses the elastic element 5, and this creates a force the closure of parts 3 and 4 of the calibrating rod. Subsequently, the workpiece is deformed 9. and the design of the forging 10 in the working cavities of the upper 1 and lower 2 halves of the stamp with an increasing force closure of the parts of the calibrating rod.

Invention Formula A punch for stamping parts from tubular blanks containing a movable moving and lower stationary halves, an annular ejector and a calibrating rod, differing in that, in order to expand technological capabilities and reduce the cost of production products, the calibrating rod is made of two separate parts, moreover, the upper part is set in the upper half of the punch with a possibility of relative axial n displacement and is spring loaded with an elastic element. the calibrating rod returns to its original position under the action of the elastic element 5. Then, after the heads, 8 and 8, are engaged with the protrusions of the upper half of the punch, the connecting rods 8 and the annular ejector 6 move upwardly relative to the lower half of the punch 8 and the forging 10 is pushed out of the lower half. stamp and eat it from the bottom of the calibrating rod, after which the cycle repeats. Such a punch design allows you to reduce the required pusher stroke and increase the clearance between the upper and lower halves of the punch, which makes it possible to load more than one pitch of the bottom of the punch. five 0 35 expended energy.
