The invention relates to the processing of wire and the manufacture of parts from it and can be used to obtain frames from wire rod used for wrapping bags, for example, aluminum ingots.

The purpose of the invention is to increase the productivity of the device by ensuring the continuity of the process of manufacturing parts.

FIG. 1 shows a device for the manufacture of wire parts, a side view; in fig. 2 shows a kinematic diagram of the device (the mechanisms for cutting and intercepting are shown on opposite sides of the bending mandrel); in fig. 3 is a view A of FIG. 2; in fig. 4 shows a section in FIG. 3.

The device has a frame 1, on which a holder 2 for a coil with wire 3 is installed, straightening and tensioning units 4, a winding mechanism 5 and an actuator 6. The swiveling bending mandrel 7 is rigidly connected to the bevel wheel 8 and gear 9 with the possibility of rotation around the stationary axis 10, on which the central gear 11 is rigidly fixed.

The winding mechanism 5 consists of a movable hinge 12 connecting the rod 13 to the guide rollers 14 and the rocking arm 15, a spring-loaded pusher 16S interacting with the cam 17 rigidly connected to the gear 18, which is in engagement with the gear 9 and able to rotate around the stationary axles 19.

The cutting mechanism 20, made in the form of scissors, is mounted on a bending mandrel 7 and a spring-loaded pusher 21 interacts with a cam 22 rigidly connected to a gear wheel 23 engaged in gear with a gear 119 and rotating around an axis 24 rigidly fixed on the mandrel 7 .

On the rotary bending mandrel 7 (Fig. 3), on the side opposite to the cutting mechanism 20, two single-arm rotary bending arms 25 pivotally connected by means of rods 26 with a spring-loaded pusher 27, interacting with a cam 28 rigidly connected with a gear, are installed in the bend corners. wheel 29 engaged with gear 11 and having the ability to rotate around axis 30,

rigidly connected to the swivel mandrel 7.

The interception mechanism 31 consists of a cylinder 32 swinging about axis 33, two bearings 34 mounted on a mandrel 7, a through spring rod 35, one end of which is connected to the axis 36 of the clamping jaws 37, and the other end interacting with the mortise cam 38 connected with gear wheel 11 and having rotation about axis 40 rigidly connected with mandrel 7. Shanks 41 of jaws 37 enter into grooves 42 of stops 43 of cylinder 32.. The slot cam 38 has two face workers, surfaces 44 and a radial work surface 45. The bevel gear 8 is engaged with the bevel gear 46 of the drive 6.

The device works as follows.

At the initial moment, when the axis 36 of the clamping jaws 37 of the interception mechanism 31 is in position a (FIG. 2), the end of the wire of the coil 3 is clamped and the drive 6 is activated. Through the bevel gear 46 and the wheel 8, the drive rotates the rotary bending mandrel 7, This rod 13 of the mechanism 5 winding roller 14 raises with

: given step on the mandrel wire. i The intercept mechanism 31 locks the axis

36 clamped jaws 37 in position. and for 1.5 turns (with a two-legged frame). Then, under the action of the cam 38 (its surfaces 44 and 45), the rod 35 first moves the axis 36 of the tufts 37 to position b, while the jaws 37, abutted by the shanks 41 into the stops 43, expand, then the rod 35 rotates the cylinder 32 around the axis 33 of the supports 34 and accordingly moves the axis 36 of the jaws 37 to the position in, after which the rod 35 moves the axis 36 of the jaws 37 to the position g, in which the jaws 37 clamp the winding wire branch. At this point, the mandrel 7 makes two turns. After clamping the cutting mechanism, the principle of operation of the cutting shears of which is similar to the action of the clamping jaws of the intercept mechanism cuts the wire. Then, the spring-loaded pusher 27 falls into the trough of the cam 28 and with the help of the t 26 turns the turn, 7
