Description

A semiautomatic incision machine is known; 1 H11 rivet ends. ; CL Achieving frame, drive, hopper with a disk for feeding rivets into an inclined channel, equipped with a cut-off device for issuing rivets one by one in K.TcmJi sled, feeding their rivets to the device for cutting its end.

The device for cutting the ends of the rivets has a complex structure in the form of a rotating, vertical plane of the disk with a saw-tooth crest.

In the described semiautomatic device for the purpose of simplifying the hygroscopic structure, the device for cutting the end of the rivet is made in the form of a double-pointed blade. a vertical plane carrying a knife-pua -1son at the end but a cut shape at the end of the rivet; NOL: - Cuatson enters periodically into the rectangular opening of the compacting matrix, which has a through horizontal opening for a single rifle end punch on one side and a rivet end punch on the other side, and to enter the ejector of a cut shank on the other side. The ejector is mounted on a sled, which feeds the rivets into the matrix and is moved back and forth displaceably along the bed guides with two wedges, which are easily connected to the punch knife.

FIG. 1 shows a diagram of a semiautomatic device; in fig. 2-rivet with cut end.

The semiautomatic device includes a stanchion / and, made in the form of a pulley 2, mounted on the shaft 3 and receiving a rotation from the electric motor (shown on the drawing). Ka end of va.la 3 naglu.ho fixed eccentric, which reports the swinging movement through t gu 5 fork 6, mounted on the end of the two shoulders lever 7; the other arm of the lever carries a spring-loaded dog 8, which informs the movement of the hrygyuk 9; Prisoner V11utri bun # 128736 was planted on a single shaft with a ratchet

Kerra 10 for Zack 1E1; drive J /, feeding rivets from bsnker 10 into inclined channel 1§, ъ a cutter 13 is installed to dispense rivets 14 all the way into the pliers 15 of the slide 16, which feed the rivets into the stationary: lis-matrix 17. The slide 16 moves reciprocatingly along .. Lravl 7S of the bed 1, two wedges 19, rigidly connected 1and with a rod, m 2.0., hinged on the eccentric 4 at point 21. The connecting rod 20 communicates movement through the connecting arm 22 attached to it 22 double arm 23, one arm of the lever is under by the action of the spring 24, and the second shoulder is connected to the cutter 13 dl when keeping it in action when issuing rivets J4 in bream 15. Shatzn 20 carries at its end a knife-punch 25. made in the form of a cut at the end of rivet 14; the knife-punch periodically enters the rectangular hole 26 of the sliding matrix 17, which has a through horizontal hole 27 for the rivet 14 end, which is inserted into it from one side of the knife-cutter 25, and from the other side to enter the ejector 28 of the cut rivet. The ejector 28 is installed on the slide 16, which feeds the rivets into the matrix 17, and pushes the rivet out of the die hole 27 during the return stroke of the slide M, which MI is informed of by the springs 29.

The cutting of the ends of the rivets on the crawling machine is as follows.

The uncut rivets 14 fall asleep into the hopper 10, from where they are driven by the disk rotating from the eccentric 4 through the pull 5 and the ratchet gear 8-9, are fed into the inclined channel 12; the rivets 14 roll down on it under the action of their own weight to the trimmer 13, which, when it is deflected by the thrust of 22, the two shoulders of the lever 23, outputs the rivets 14 one by one into the tongs 15 of the sled 16. The sled 16, moving along the guides 18, serves the rivets into the horizontal opening 27 dies 17 for a knife-punch 25 moving in a vertical plane from the eccentric 4 with the aid of a crank 20. Knife-punch 25 cuts the end of the rivet 14 fed under it, after which the slide 16 under the influence of the spring 29 returns to its original position; at the same time, the ejector 28 mounted on them creates a rivet cut FROM the matrix 17, and in its place a new rivet is fed from the inclined channel 12 into the tongs 15 of the slide 16.

Claims (2)

1. A crawler for cutting the ends of rivets, including a frame, a drive, a cylinder with a disk for feeding rivets into an inclined channel equipped with a cut-off device for issuing rivets one at a time in a flare, and a sled feeding the rivets to a device for cutting its end, characterized in that In order to improve the construction of the semiautomatic device, the device for cutting the end of the rivet is made in the form of a rod moving in the vertical plane carrying The end of the knife-punch is in the form of a cut at the end of the rivet, which periodically enters the rectangular hole of the fixed matrix, which has a through horizontal opening for the rivet end to be inserted into it from one side under the punch knife and on the other side to enter the ejector of the cut rivet. 2. Semi-automatic pop. 1, characterized in that the ejector of the cut rivet is mounted on a sled, which feeds the rivets into the matrix, displaced reciprocally along the base plates with two wedges rigidly connected to the scapular.
