(54) DEVICE FOR WINDING WIRES

I

The device for winding wire relates to the field of metal forming and, in particular, can be used in wire processing workshops.

A device is known which comprises a coil mounted on a frame rotating on a drive axis on which a wire is wound. To evenly distribute the wire along the length of the coil, there is a pickup mechanism moving reciprocating parallel to the axis of the coil, made in the form of a guide leash mounted on the slide, driven by a copier, made in the form of a rotating disk mounted on a drive axis parallel to the axis of the coil and kinematically associated with it 1.

Such a device is complicated in construction. Its complexity is caused by the necessity of strictly observing the Step of the turns of the wire on the coil depending on the diameter of the wire and matching with the established step of the speed of movement parallel to the axis of the pickup mechanism coil.

It is also known a wire winding device comprising a fixed rack, a drive axle with a reel, guide rollers, a spring-loaded clamp against the mechanism for laying the turns of the wire 2.

A disadvantage of this device is also its complexity.

J The purpose of the invention is to simplify the structure.

This is achieved by the fact that the mechanism for

laying the turns of wire is made in the form

freely mounted on the axis of the beam,

and adjusting screws in contact

10 with a yoke.

FIG. 1 shows a general view of the device with a cross-section along a reel; in fig. 2, view A in FIG. one.

The proposed wire winding machine comprises a rack 1, with a drive axis 2 mounted thereon, on which a bobbin 3 is fixed, on which a wire 4 is wound, which enters the bobbin through guide rollers 5.

On the rack 1, there is a hinged flat clamp 6, located between the shoulders of the reel 3 and pressed against the reel by the spring 7.

A support 8 is fastened on the support 1, on which an freely rocking arm 10 is mounted on the axis 9, on the lower plane of which the wire 4 is being wound reeling onto the reel 3. To limit the swing of the rocker arm 10, the adjusting screws 11 are fixed on the bracket 8. ZLii-. Installing the reel 4 on the axis 2 and removing it from the axis on the rack 1, a fixture 12 is fixed, which interacts with the shank 13 of the pressing 6. The device works as follows. For winding the wire on the reel 3, the last one is fixed on axis 2. To do this, manually press out the clamp 6 and the shank 13 is fixed by the latch 12. The reel 3 is put on axis 2, the end of the wire 4 is passed through the guide rollers 5, held under the yoke 10, is fixed on the reel 3 and the axis 2 is manually rotated one turn, winding one turn of the wire on the reel. Then the hook 12 is pressed out and, under the action of the spring 7, the clamp 6 presses the coil of the wire to the reel 3. Next, the axis 2 is driven and the wire under the action of the rotating reel 3 is wound tightly on its cylindrical part between the collars and the coil to the turn. The yoke 10 under the action of tensioning the wire will take an inclined position, resting its end on the adjusting screw. The inclined plane of the rocker arm 10 at the beginning of a row of wire being wound will prevent the coils from coming off the reel 3, after passing through the middle of the reel the rocker arm 10 will tilt in the opposite direction and force it onto the wire to allow it to be easily wound on the reel board

Fig. 1 The subsequent row of turns is formed by restricting the movement of the wire to the side of the reel 3. The wire will depress the clamp 6 and when navigating will be located in the recesses between the turns of the previous row. At the end of the winding, the clamp 6 is retracted from the reel 3 and the shank 13 is fixed in the retracted position by the latch 12. After that, the reel of wire is removed from axis 2 and an empty reel is installed instead. The angle of inclination of the rocker arm 10 is set using the adjusting screws 11, depending on the diameter of the winding wire and its elastic properties. The use of this device as a mechanism for laying turns of the rocker arm greatly simplifies the design of the device. An apparatus for winding a wire comprising a fixed rack, a drive axis with a reel, guide rollers, a spring-loaded clamp and a mechanism for laying the turns of wire, characterized in that, in order to simplify the design, the mechanism for laying the turns of the wire is designed as freely mounted on axis of the rocker arm, and adjustment screws in contact with the rocker arm.
