Abstract

The invention relates to the manufacture of locking rings of tape and allows you to simplify the design and expand the technological capabilities of the machine. During the forward run of the field 27 of the zuna 2, the feed mechanism 3 rigidly connected with it feeds the belt 32 and feeds it into the bending roller head 4, where it is bent into the ring. During the return stroke of the slider 2, the mechanism of segments 5 which is kinematically connected to it through the pusher 1, which, with its block of type 3 anchor matrix 10, cuts off the already finished ring from the belt 32. Mening the blocks 10, adjusting the position of the roller 27, moving with the help of the screw 29 the position of the block 10 relative to the bending head 4, as well as changing the stroke length of the slide 2, the machine quickly rearranges to a different size of rings. 12 il. a (L oo with so

The invention relates to the processing of metals by pressure and can be used in the manufacture of circlips from a tape by plastic deformation.

The purpose of the invention is to simplify the design and expand the technological capabilities.

FIG. 1 shows an automaton, a general view; in fig. 2 and 3 - the same plan view; in fig. 4 is a section A-A in FIG. 3; FIGS. 5 and 6 are section BB in FIG. 2; in Fig. 7 — a quick-detachable punch block — a matrix; in fig. 8 is a sectional view BB in FIG. 7; FIG. 9 shows the retaining ring in FIG. 10 - quick release unit; in fig. 11 - section GG in FIG. ten; FIG. 12 shows a retaining ring with a different direction of the ends of the cut.

The machine includes a reciprocating drive, made in the form of a pusher 1 connected with a slider 2, a belt-falling mechanism 3, a bending roller head 4

and mechanism 5 segments.

The mechanism 5 is cut kinematically connected with the drive of the reciprocating movement by means of the wedge mechanism 6 with the wedge-dog-dog 7 and the latching spring 8, which is connected directly with the pusher 1.

The mechanism 5 is provided with spacer blocks 9 and 10 of the punch-matrix type (Fig. 7, 8, 10 and 11), which can be adjusted in the guides of the bending head 4. Blocks 9 and 10 contain a punch 11, a matrix 12, a connecting pin 13, a return spring 14. The block 9 is further provided with a pusher .15 with a spring 16. The blocks 9 and 10 have grooves 17, by means of which they are mounted in the guides 18 of the bending head 4. The punches 11 of the blocks 9 and 10 can be made composite (Fig. 10), They are equipped with a safety pin 19,

Blocks 9 and 10 communicate with the pusher-1 by means of a rod 20 equipped with a return spring 21 and a rotary roller 22 in contact with a wedge-pawl 7 “The rod 20 is movably mounted in the housing 23 of the mechanism 5. The housing 23 is provided with supporting rollers 24 in contact with the pusher 1,

The bending head 4 has bending rollers 25 fixed to fixed axles 26 and an adjustable roller 27 with an adjustment mechanism 28, as well as a screw 29 for moving the blocks 9 and 10 along the guides 18.

The adjustment mechanism 28 is provided with screws 30 for adjusting the flatness of the snap rings made on the car. Washers 31 mounted on rollers 25 o serve the same purpose.

The feed mechanism 3 of the tape 32 is made in the form of a system of spring-loaded rollers 33 and a wedge 35 placed opposite them in the holder 34, both the rollers and the wedge being installed in the case 34 with the possibility of reciprocating movement, and the case 34 provided with mutually inclined working surfaces mi 36 and 37 about

The machine is also equipped with a stand 38 (Figs. 3 and 6) and guides 39 for feeding the tape, as well as a brake 40.

The machine works as follows.

The tape 32 from the drum (not shown) is passed through the correct device (not shown), then between the guides 39 and tucked between the rollers 33 and the wedge 35 of the feed mechanism 3. At. the forward movement of the slider 2, the feeder 3 which is rigidly connected with it, picks up the belt 32 and moves it inside the wiring formed by the guide 39, brake 40 and rollers 25 and 27 of the bending head 4. At the same time, the belt 32, the passage between the rollers 25 and 27, is bent in ring.

During the forward movement of the slider 2, the pusher 1 associated with it moves, while the stop-pawl 7 rotates around its axis under the action of the roller 22 and passes into the groove of the pusher 1, stretching the spring 8. The piece mechanism 5 does not work.

When the reciprocating movement of the drive (slider 2 and pusher 1) is applied, the brake 40 clamps the belt 32, fixing its position, and the rollers 33 and the wedge 35 of the feed mechanism 3 open, allowing the mechanism 3 to return to its original position with the slide 2 on tape 32,

Simultaneously, the stop-pawl 7 acts on the roller 22, moving the rod 20 of the mechanism 5 segments, which in turn interacts with the punch-matrix block (9 or 10), which carries out a piece of tape 32 with the simultaneous formation of both edges of the cut. ring that does not require additional machining.

The finished rings roll down along the guide to the container (not shown), and then the cycle repeats.

The transition to the manufacture of rings of other diameters is carried out by changing the roller 27 using the adjustment mechanism 28, as well as shifting along the block guides 18 of the segment (9 or 10), which is carried out with the help of a screw 29.

The transition to the manufacture of rings with a different shape of the slice (Fig. 9 and 12) is carried out by replacing the block with an S matrix.

The machine is also equipped with a mouthpiece. A device for straightening the tape 32, reeled off the drum, and a device for cleaning it of grease.

The proposed device is characterized by simplicity of design, reliability in operation, small dimensions and metal content.
