The various embodiments listed in the utility model are only used to illustrate the utility model, and are not used to limit the scope of the utility model. Any obvious modifications or changes made to the utility model do not depart from the spirit and scope of the utility model.

[0023] See also Figure 1-5 As shown, a wire feeding mechanism of a cold heading machine proposed by the utility model comprises a frame assembly 1 and a feeding assembly 3 assembled on the frame assembly 1, the frame assembly 1 comprises a base 101 and a protective cover 102 hingedly mounted on the front end of the base 101 and wrapped around the outside of the feeding assembly 3, the feeding assembly 3 comprises a fixed plate 301 fixedly mounted on the top of the base 101, two symmetrically distributed pressing wheels 303 are rotatably mounted on the front end of the fixed plate 301, and the front end of the fixed plate 301 and located at A traction wheel 4 is rotatably installed at the bottom of the two pressure wheels 303. The pressure wheel 303 extends into the groove of the traction wheel 4 in the shape of an annular protrusion. Anti-slip strips 304 are distributed in an annular array on the surface layer of the pressure wheel 303. Movable grooves 401 distributed in an annular array are provided on the inner side of the traction wheel 4. An extended movable seat 402 is slidably installed inside the movable groove 401. A buffer spring 405 is fixedly installed between the movable seat 402 and the movable groove 401, and a rubber pad 403 is adhered to the surface of the movable seat 402.

[0024] Based on the above-mentioned structural setting, the wire feeding mechanism of the cold heading machine is composed of a frame assembly 1 and a feeding assembly 3, wherein the frame assembly 1 can support the feeding assembly 3, and the feeding assembly 3 can be used to flexibly convey the wire without slipping, and can avoid the concavity of the wire surface caused by strong squeezing of the wire, so that the wire can maintain a good appearance state, and effectively improve the production quality of the product. Specifically, in the working process, by placing the wire between the pressure wheel 303 and the traction wheel 4, the convex part of the pressure wheel 303 can press the wire into the movable seat 402, and the movable seat 402 can be telescopically movable in the movable groove 401, and the movable seat 402 can be automatically adjusted according to the thickness of the wire, and the elastic action of the buffer spring 405 can make the movable seat 402 flexibly squeeze the wire, so as to avoid strong squeezing of the wire. The force extrusion causes the surface of the wire to be dented. When the wire is extruded by the movable seat 402, the rubber pad 403 can be in close contact with the wire. At the same time, the rubber pad 403 can be deformed when being extruded, so that the rubber pad 403 can wrap the wire, increase the friction between the wire and the rubber pad, and can flexibly extrude the wire without slipping. By driving the traction wheel 4 to rotate, the pressure wheel 303 can be driven to rotate synchronously, and the wire can be driven to be transported more conveniently, so that the wire can be transported to the processing area of ​​the cold heading machine for processing. The protective cover 102 can conveniently protect the pressure wheel 303 and the traction wheel 4 to avoid safety hazards caused by accidental touch by personnel, thereby improving the safety effect when feeding the wire. At the same time, by flipping the protective cover 102 outward to open it, it is convenient for staff to perform maintenance operations on the feeding component 3, thereby improving the use effect.

[0025] Furthermore, a fixing frame 107 is fixedly installed on one side of the base 101, a guide cylinder 105 is fixedly installed on the top of the fixing frame 107, and a horn cover 106 is fixedly installed on the side of the guide cylinder 105 away from the base 101. The fixing frame 107 can support the guide cylinder 105, so that the guide cylinder 105 can correspond to the pressure wheel 303 and the traction wheel 4. By passing the wire through the guide cylinder 105, the guide cylinder 105 can be conveniently used to position the wire, so that the wire can enter between the pressure wheel 303 and the traction wheel 4 horizontally, thereby improving the stability effect during feeding. The horn cover 106 can be used to limit the wire into the guide cylinder 105 to avoid bending and being unable to pass through the guide cylinder 105.

[0026] Further, the bottom of the base 101 is equipped with a support assembly 2, and the support assembly 2 includes a support leg 201 fixedly installed at the bottom of the base 101. Among them, the support leg 201 can conveniently support the frame assembly 1, so that the device can be conveniently placed at the feed port of the cold heading machine for use.

[0027] Furthermore, an observation window 103 is provided on the surface of the protective cover 102, and the protective cover 102 is fixed to the fixing plate 301 by a fixing bolt 104. The observation window 103 can facilitate the staff to observe the running state of the feeding assembly 3 during the feeding of the wire, so that when a fault occurs, it is convenient to check and perform maintenance operations in time, and the fixing bolt 104 can facilitate the fixing of the protective cover 102 to the fixing plate 301, so as to prevent the protective cover 102 from turning over and falling off.

[0028] Furthermore, a servo motor 302 is fixedly installed at the rear end of the fixed plate 301, and the output shaft of the servo motor 302 passes through the fixed plate 301 and is fixedly connected to the traction wheel 4. The servo motor 302 can conveniently and accurately control the rotation of the traction wheel 4, and can effectively realize the accurate feeding operation of the wire.

[0029] Furthermore, the pressing wheel 303 and the traction wheel 4 are installed in a transmission manner through a transmission gear 305, and the surface of the rubber pad 403 is provided with anti-skid convex particles 404 in a circular array. The transmission gear 305 can make the traction wheel 4 rotate while driving the pressing wheel 303 to rotate in the opposite direction, so as to form a traction operation for the wire, and facilitate the transportation of the wire. The anti-skid convex particles 404 can increase the friction between the rubber pad 403 and the wire, and reduce the occurrence of slipping.
