[0002] The spring wire surface treatment device is used to improve the surface finish and roughness control of the wire. It includes rough grinding and fine grinding processes, which use abrasive wheels or other grinding tools to remove surface roughness and unevenness to ensure surface flatness and consistency. This device not only improves the appearance of the spring wire, but also improves its corrosion resistance and mechanical properties.

[0003] The patent announcement number CN215942495U discloses a surface treatment device for oil-quenched spring steel wire, which belongs to the technical field of oil-quenched spring steel wire. The surface treatment device for oil-quenched spring steel wire includes a steel wire bundling device, a surface oxide peeling device, and a grinding device, which is characterized in that: a roller is arranged on one side of the surface oxide peeling device, and peeling wheels one, two, three, and four are arranged at the lower end of the surface oxide peeling device. The oxide on the surface of the spring steel wire is peeled off by rotating the four groups of peeling wheels. The grinding device is provided with a coarse grinding roller and a fine grinding roller. The spring steel wire is processed more finely by grinding with two rollers. An upper mold is arranged on the upper end of the steel wire straightening device, and a lower mold is arranged on the lower end of the steel wire straightening device. A steel wire through-hole is provided between the upper mold and the lower mold. The polished steel wire is straightened and bundled by the straightening device, thereby completing the treatment of the surface oxide of the oil-quenched spring steel wire without generating harmful substances.

[0004] However, the current surface treatment device has the following problems: the surface treatment device uses a rotating rolling method of a shelling wheel to perform preliminary treatment on the oxides on the surface of the spring steel wire, but the oxides on the surface of the spring steel wire may be unevenly distributed in shape and density, and some areas may be more difficult to treat than other areas. The simple rolling method of the shelling wheel cannot evenly remove the oxides, resulting in some oxides remaining, which will affect the effect and quality of subsequent treatment of the spring steel wire. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a spring steel wire surface treatment device, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a spring steel wire surface treatment device, including a device body, guide roller frames are fixed on both sides of the top of the device body, four annular frames are fixed on the top of the device body, and the four annular frames are staggered.

The elastic serrated plate is located inside the through groove of the hollow wheel, and two hinged rods are hinged on one side of the slide rod close to the inner wall of the hollow wheel. The ends of the two hinged rods away from the slide rod are respectively hinged to the inner walls of the two flowering slip rings. When the hollow wheel rotates, the cross rod will drive the rotation of the cross rod, and the slide rod will slide along the elliptical groove of the elliptical groove plate. The slide rod is driven by the elliptical groove of the elliptical groove plate to reciprocate along the outside of the cross rod toward the center of the hollow wheel. Each time the slide rod moves toward the center of the hollow wheel, the slide rod pulls the hinged rod to drive the flowering slip ring to move along the through groove of the hollow wheel toward the middle of the hollow wheel. The two flowering slip rings squeeze the elastic serrated plate, and the elastic serrated plate bulges and deforms and leans against the spring steel wire.

[0008] According to the above technical solution, a shaking-off device is arranged on the top of the hollow rotating wheel, and the shaking-off device includes a telescopic column, a T-shaped rod, and a knocking column. The telescopic column is fixed on the top of the elliptical groove plate, the T-shaped rod is fixed on the top of the telescopic end of the telescopic column, and the knocking column is fixed on the bottom of the side of the T-shaped rod away from the telescopic column.

The hemispherical shape of the knocking column is located on the movement trajectory of the convex ball block of the hollow rotating wheel. The bottom of the knocking column contacts the top of the hollow rotating wheel. When the hollow rotating wheel rotates, the convex ball block on it will be driven to rotate. The convex ball block of the hollow rotating wheel pushes the hemispherical shape of the knocking column to drive the knocking column to move upward. The knocking column drives the telescopic end of the telescopic column to stretch through the T-shaped rod. When the convex ball block of the hollow rotating wheel no longer pushes the hemispherical shape of the knocking column, under the elastic force of the telescopic column, the telescopic end of the telescopic column drives the knocking column to reset and move downward through the T-shaped rod. The knocking column knocks the hollow rotating wheel, the hollow rotating wheel vibrates and drives the spring steel wire to vibrate.

[0010] According to the above technical solution, stabilizing devices are arranged on both sides of the top of the device body, and the stabilizing devices include a U-shaped frame, a positioning rod, a pressing plate, and a friction plate.

[0011] According to the above technical scheme, the stabilizing device includes an L-shaped slot plate and a connecting column. The L-shaped slot plate is fixed to a side of the friction plate close to the annular frame, the connecting column is fixed to an eccentric bottom portion of the cross bar, and the connecting column is located at a hollow rotating wheel on a side away from the center of the device body. A strip groove is provided on the top of the side of the L-shaped slot plate away from the friction plate, and the connecting column is slidably installed inside the strip groove of the L-shaped slot plate.

[0012] The present invention provides a spring steel wire surface treatment device, which has the following beneficial effects:

[0013] (1) The present invention arranges a shelling device so that the hollow rotating wheel drives the sawtooth bar to roll the surface of the spring steel wire. The sawtooth bar can increase the contact area and cutting force between the hollow rotating wheel and the surface of the spring steel wire, so that the hollow rotating wheel can more effectively strip the oxide on the surface of the spring steel wire when rotating; at the same time, the hollow rotating wheel, the cross bar, the sliding bar, the elliptical groove plate, the hinged rod, and the flower slip ring cooperate to squeeze the elastic sawtooth plate, and the elastic sawtooth plate bulges and deforms and leans against the spring steel wire, so that the transverse saw teeth of the elastic sawtooth plate further roll the oxide layer on the surface of the spring steel wire, thereby further improving the efficiency of removing the oxide layer on the surface of the spring steel wire.

[0014] (2) The present invention provides a shaking-off device, so that the hollow rotating wheel, the knocking column, the T-shaped rod, and the telescopic column cooperate to drive the knocking column to knock on the hollow rotating wheel, and the hollow rotating wheel vibrates and drives the spring steel wire to vibrate, which is conducive to shaking off the oxide layer adhering to the surface of the spring steel wire, thereby indirectly improving the efficiency of removing the oxide layer on the surface of the spring steel wire; at the same time, the T-shaped rod, the L-shaped connecting rod, the fixed ring, and the conical ring cooperate to drive the scraper rod to scrape the gap between two adjacent sawtooth bars. The scraper rod scrapes the oxide layer impurities remaining between the two adjacent sawtooth bars away from the sawtooth bars, thereby avoiding the problem that when the sawtooth bars roll over the surface of the spring steel wire, the oxide layer impurities will affect the contact area between the sawtooth bars and the surface of the spring steel wire.

[0015] (3) The present invention sets a stabilizing device so that the pressing plate can press the spring steel wire on the top of the friction plate. Pressing the spring steel wire can help ensure the stable transmission and position of the spring steel wire in the processing equipment, thereby ensuring the stability of the spring steel wire processing process and the accuracy of the processing position; at the same time, the hollow rotating wheel, the cross bar, the connecting column, and the L-shaped groove plate cooperate to enable the friction plate to drive the spring steel wire to twist. By driving the spring steel wire to twist, the hollow rotating wheel can contact and process the entire surface of the spring steel wire more evenly, thereby avoiding the situation where the spring steel wire is locally under-processed.
