Technical Field

The invention relates to the technical field of metal drawing equipment, in particular to a guide wheel mechanism of a wire drawing machine.

Background

Wire drawing machines are commonly used to subject a wire-like material to a drawing process to wind it around a particular workpiece to form a coil. The husking wheel is an important part of the wire drawing machine, and is used for drawing wires and guiding the wires to be transmitted in order to keep a walking path of the steel wires smooth and not to interfere with equipment; in addition, in the process of the steel wire moving on the shelling wheel set, the rust layer of the steel wire falls off through repeated bending and friction, so that the steel wire has more uniform texture, smoother surface and better bearing performance. The steel wire has friction with the guide wheel in the walking process, so the service life of the guide wheel is limited, and the guide wheel needs to be replaced after being worn. The existing guide wheel is mostly of an integrated structure, the requirement on the material is high in order to guarantee the wear resistance, and the hardness and the wear resistance are increased through a local spray welding or integral quenching process after the guide wheel is machined and formed. The guide wheel is high in manufacturing cost, and the whole guide wheel needs to be scrapped after being worn, so that material and process waste is serious. Chinese patent publication No. CN107316741A discloses a drawing guide wheel and a wire drawing machine, the guide wheel includes a wheel body, two peripheral edges of the wheel body extend outwards, a circle of V-shaped wheel groove structure is provided, lightening holes are provided on the wheel body, and a fixing ring is provided in the middle of the wheel body. The wheel body reduces the material usage amount of the wheel body through the spoke structure, and achieves the purposes of increasing the outer diameter, reducing the rotating speed and reducing the material usage amount. However, the wheel body needs to be processed and molded through complex machining, and can only be integrally scrapped after being worn, so that cost waste is caused, and the problems cannot be solved; and the whole thinning of wheel body can influence rigidity, at the in-process of traction wire, produces mechanical vibration easily when traction force is great, has increased the alternating stress of steel wire, probably leads to the steel wire to drop when serious, influences wire drawing effect and steel wire intensity.

Detailed Description

The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.

Fig. 1 shows a schematic structural diagram of the present invention:

the invention provides a high-strength wire drawing machine peeling wheel which comprises a threaded wheel disc 1, a through hole wheel disc 2 and a rotating shaft 4, wherein the small end of the threaded wheel disc 1 faces the small end of the through hole wheel disc 2, the threaded wheel disc 1 is connected with the through hole wheel disc 2 through screws, the rotating shaft 4 is respectively connected with the threaded wheel disc 1 and the through hole wheel disc 2 through a bearing 6, a wheel groove 7 structure is formed between the threaded wheel disc 1 and the through hole wheel disc 2, a wheel core 3 is arranged at the bottom of the wheel groove 7, and a groove is formed in the outer ring surface of the wheel core 3.

When the wire drawing machine is used, the husking wheel is arranged on a support corresponding to the wire drawing machine, a wire rod passes through the groove in the outer annular surface of the wheel core 3, and the threaded wheel disc 1, the through hole wheel disc 2 and the wheel core 3 rotating shaft 4 rotate under the action of friction force to complete the guiding of the wire rod.

Because the wire rod generally only rubs with the wheel core 3, the material requirements on parts such as the threaded wheel disc 1, the through hole wheel disc 2 and the like are reduced, and the material cost and the manufacturing process difficulty are reduced; when the abrasion occurs, only the wheel core 3 needs to be replaced, and the whole mechanism does not need to be scrapped; and the wheel core 3 is small in size and simple in shape, and can be completed only by being matched with simple machining after preliminary molding, so that the waste of materials and processes is greatly reduced. In addition, the invention is convenient for carrying out large-batch heat treatment on the wheel core, improves the surface mechanical property and reduces the process cost; when the original integral husking wheel is adopted, the influence of wing-shaped structures at two ends of the wheel groove is received due to the lower position of the wheel groove structure, the cooling speed is reduced during heat treatment, and the wear resistance of the wheel groove is influenced. The invention thus also improves the durability of the peeling wheel. In addition, when the invention is used, the mechanical vibration can be effectively avoided, and the conditions of increasing the alternating stress of the steel wire and the vibration and falling of the steel wire are avoided.

The tip of screw wheel dish 1 is equipped with columniform boss A9, and the tip of through-hole rim plate 2 is equipped with columniform boss B10, and boss A9, boss B10's outer anchor ring and the cooperation of wheel core 3, a plurality of screw holes have been arranged along the annular to boss A9 terminal surface, and boss B10 has arranged the through-hole corresponding to the screw hole.
