I yes in the groove of the mandrel; nafig.2v- clamp and bending output; in fig. 2d - formation of spiral contact; in fig. 2d - formed output before serving for the next operation); in fig. 3 — mandrel of the mechanism for forming a short lead, cross section; in fig. 4-6 are views A, B and C in FIG. 3, respectively; in fig. 7 is a short lead generation circuit; in fig. 8 - wire feed rollers; in fig. 9 - section G-Y in FIG. Bf in FIG. 10 - capacitor section with soldered leads from the contact part of the long lead; in fig. 11 - the same, from the side of the contact part of the short you-b water.

A device for making and soldering wire leads includes a vibrating hopper 1 for feeding sections 2 of capacitors, a transporting mechanism, 3, wire feed mechanisms 4 and 5, a long lead section b mechanism, a long lead forming mechanism 7, a short terminal forming mechanism 8, mechanisms 9 and 10 soldering and drive 11.

The transporting mechanism 3 contains a movable 12 and a fixed 13 slats. The slide rail 12 is associated with the eccentrics 14 cooperating with the gear wheel 15 mounted on the shaft 16 of the drive 11.

The wire feed mechanisms 4 and 5 comprise cranks 17, connecting rods 18 connected to gears 19. Feed rollers 20-22 are mounted on gears 19 axes. On the upper roller 22 of the mechanism for feeding the short pin. longitudinal grooves 23 are made, the distance between which along the periphery is equal to the length of the output terminal.

The long run mechanism b is composed of directions of the sleeve 24 and the knife 25 with the ability to interact with the cam 26 mounted on the camshaft 27 of the drive 11.

The long lead formation mechanism 7 has clamping jaws 28 and 29, on which gears 30 and 31, a mandrel 32 and a lever 33, controlled by a cam 34, are fixed. 28, a groove 38 is provided for forming a lead. The mandrel 32 is provided with a groove 39, a protrusion 40 and a gear 41 interacting with the toothed sector 42 of the cam 43. To move the mandrel 32, the lever 44 serves to interact with the cam 45.

The short output mechanism 8 includes a rotating mandrel 46 and a rocking lever 47. On the mandrel 46, a knife 48 of the short-end cutting mechanism is mounted, spring-loaded 49, and a protrusion 50 is made on the front end of the mandrel 46 offset from the central

holes 51, designed by dp passage of the wire .- The lever 47 is connected through tgu 52 and the lever 53 with the cam 54. The lever 47 is equipped with a stop 55, spring-loaded spring 56, and a protrusion

0 57. Stop 55 has three working surfaces 58-60.

The mechanisms 9 and 10 of the soldering contain 61 mounted contact devices 62 with contacts 63. Rods

The 5 61 are designed to interact with the cams 64 receiving rotation from the shaft 16 through a gear system. The mechanism 10 soldering short output also contains the safety device 65,

n installed on the contact device 62.

The machine works as follows.

Section 2 of the capacitor from the vibrator coil 1 enters the fixed rail 13 of the mechanism 3. When the eccentrics 14 are rotated, the movable rail 12, lifting, carries the section to the next working position. Rollers 20 to 21

0 of the mechanism 4, driven in rotation by means of the crank 17 and the connecting rod 18 through the gears 19, serves to feed the wire into the central hole of the section (Fig. 2a). Then knife 25 mechanism

5 6, driven from the cam 26, cuts the output, and the transporting mechanism 3 transfers the section with the output to the next position, where the mechanism .7 forms a spiral contact

0 long output. The wire is clamped with the jaws 28 and 29 under the action of the spring 36. The front part of the wire falls into the groove 39 of the mandrel 32 (Fig. 26), where it is centered.

5 The lever 33 under the action of the cam 34 bends the wire, which falls into the guide groove 38 of the jaw 28 (Fig. 2c). The mandrel 32, having received a horizontal movement from the cam 45 through the lever 44, fits close to the plane formed by the compressed jaws 28 and 29. The place of the output bending is in the end portion of the projection 40 of the mandrel 32 opposite the groove 39. After

This mandrel 32 receives a turn from the cam 43 through sector 42 and gear 41, while the wire carried by the projection 40 of the mandrel 32 bends in the guide groove 38 (Fig. 2d). Then the jaws 28 and 29 are opened and the section 2 with the formed output is moved to the soldering position (Fig. 2d). At the short lead-out position, the wire is fed by the rollers 21 and 22 of the mechanism 5 to the central 65 hole 51 which is constantly rotating.

the mandrel 46. Then, the lever 47 from the cam 54 through tgu 52 and the lever 53 raises the spring-loaded stop 55. The upper working surface 53 of the stop 55 bends the wire. Then, the bottom surface 60 of the anvil 55, under;

The rollers 21 and 22 of the mechanism 5 push the lead out of the Olravka 46, after which the feed of the output stops, despite the rotation of the rollers 21 and 22, due to the presence of grooves 23 on the roller 22. At the moment of stopping the feed, the protrusion 57 of the lever 47 presses the knife 48, which cuts the lead . The cut-off pin falls on the safety device 65, mounted 1 on the block of the contact device 62 The rods 61, receiving movement from the cams 64, move the contact devices 62, which lift the spiral contacts of the terminals to the ends of the section, then voltage is applied to the floating contacts 63 and the terminals are soldered to the section.

The introduction of the proposed device will expand the scope of application and increase labor productivity by 1.5-2 times.
