The total amount of its alloying elements reaches about 10% - 25%. It has the characteristics of high hardness, high wear resistance and high heat resistance. In order to facilitate the production of high-speed steel wire with a relatively small diameter under specific conditions, usually, the thick high-speed steel wire is drawn by continuous external force, so that the high-speed steel wire undergoes necking, and thus the thick high-speed steel wire is processed into thin high-speed steel wire.

At the same time, after the plating operation, the curing between the high-speed steel wire and the plating can be accelerated, thereby improving the plating efficiency and the anti-shedding effect.
[0027] Embodiment 2: As Figure 2 and Figure 3 , legs 110 are fixedly installed at the four corners of the bottom of the plating chamber 100. A viewing window 120 is fixedly installed on the front outer wall of the plating chamber 100. A ramp is provided on the inner wall of the bottom of the plating chamber 100.

An electric heating plate (not marked in the figure) is fixedly installed on the inner wall of the plating chamber 100.
[0028] The specific usage scenario of this embodiment is as follows: By setting the electric heating plate to heat the zinc-aluminum alloy solution inside the plating chamber 100, the zinc-aluminum alloy solution can be kept in a liquid state, facilitating the contact between the zinc-aluminum alloy solution and the surface of the high-speed steel wire to form a plating, thereby improving the protection effect on the surface of the high-speed steel wire. By setting a ramp at the bottom of the plating chamber 100, the zinc-aluminum alloy solution can flow to the central position at the bottom of the plating chamber 100 under the action of gravity, thereby improving the utilization rate of the zinc-aluminum alloy solution.
[0029] Embodiment 3: As Figure 3 , the high-speed steel wire downward pressing and guiding assembly includes vertical rods 300. There are four vertical rods 300. A top plate 310 is fixedly installed at the top of the four vertical rods 300.

[0030] The specific usage scenario of this embodiment is as follows: By setting the top plate 310 and cooperating with the vertical rod 300 for installing the synchronous cylinder 320, it is convenient to use the synchronous cylinder 320 to push the downward pressure roller 350 to cooperate with and limit the top of the thin high-speed steel wire, so as to facilitate the full contact of the thin high-speed steel wire with the zinc-aluminum alloy solution inside the plating bin 100.
[0031] Embodiment 4: As Figure 1 and Figure 2 , a synchronous cylinder 320 is fixedly installed on the outer wall of the bottom of the support frame 170. There are several synchronous cylinders 320.

A second bearing seat 340 is fixedly installed on the outer wall of the bottom of the push plate 330. The inner wall of the second bearing seat 340 is rotationally connected to the downward pressure roller 350 through a bearing and a rotating shaft. The outer wall of the bottom of the downward pressure roller 350 is in rotational contact with the outer wall of the high-speed steel wire.
[0032] The specific usage scenario of this embodiment is as follows: By driving the synchronous cylinder 320 to push the push plate 330 downward, the push plate 330 drives the downward pressure roller 350 to press down on the outer wall of the top of the thin high-speed steel wire, so that the thin high-speed steel wire can be in full contact with the zinc-aluminum alloy solution inside the plating bin 100.
[0033] Embodiment 5: As Figure 5 , the right opening is the output end of the high-speed steel wire. Both openings are rectangular inside. Wire guides are evenly fixedly installed inside the two openings. The wire guide includes a first bearing seat 160. There are two first bearing seats 160 symmetrically arranged up and down. A second guide wheel 161 is rotationally connected inside both first bearing seats 160. A folded support frame 150 is fixedly installed at the left opening. A first guide wheel 151 is rotationally connected inside the folded support frame 150 through a rotating shaft.
[0034] The working principle of the present utility model is as follows: By setting the folded support frame 150 and the first guide wheel 151 in cooperation, the thin high-speed steel wire formed after continuous multiple drawing is conveyed into the plating bin 100 to complete the surface plating re-treatment work of the thin high-speed steel wire. By setting two groups of first bearing seats 160 and second guide wheels 161 in cooperation, it is convenient to avoid rigid friction with the inside of the plating bin 100 during the process of conveying and outputting the thin high-speed steel wire from the plating bin 100, which improves the protection of the surface of the plating bin 100 and the thin high-speed steel wire, thus avoiding the phenomenon that the surface of the thin high-speed steel wire is worn or broken due to excessive friction.
[0035] Embodiment 6: As Figure 1 and Figure 4, the drying cylinder 200 is fixedly installed on the outer wall of the plating bin 100. Third bearing seats 210 are fixedly installed on the inner walls of the top and bottom at both the left and right ends of the drying cylinder 200. Third guide wheels 220 are rotatably connected to the inner walls of the third bearing seats 210. The output end of the drying cylinder 200 is fixedly connected to a reduced-diameter cap 270. A hollow plate 240 is fixedly installed at the top of the air supply pipe 230. A blower 250 is fixedly installed on the outer wall of the bottom of the hollow plate 240. A fan blade 251 is fixedly installed on the outer wall of the output shaft of the blower 250.
[0036] The working principle of the present utility model is as follows: After those skilled in the art form a thin high-speed steel wire by externally drawing a thick reinforcing bar through a thick high-speed steel wire continuous drawing machine, by inserting the starting end of the thin high-speed steel wire into the opening inside the left side of the plating bin 100, the outer wall of the thin high-speed steel wire is rotatably connected to the outer wall of the top of the first guide wheel 151. By threading the outer wall of the thin high-speed steel wire into the input end on the left side of the plating bin 100, the thin high-speed steel wire is rollingly limited between the two second guide wheels 161 on the left side. Subsequently, the thin high-speed steel wire is passed through between the two second guide wheels 161 on the right side for rolling limit, and then the thin high-speed steel wire is passed through between the outer walls of the upper and lower third guide wheels 220 for guiding, so that the thin high-speed steel wire can pass through the drying cylinder 200, and then pass through the reduced-diameter cap 270 and be led out of the plating bin 100. By driving the synchronous cylinder 320 to push the push plate 330 downward, the push plate 330 drives the downward pressure roller 350 to press down on the outer wall of the top of the thin high-speed steel wire, so that the thin high-speed steel wire can be in full contact with the zinc-aluminum alloy solution inside the plating bin 100, thereby completing the formation of a protective layer on the surface of the thin high-speed steel wire, improving the corrosion resistance effect on the surface of the thin high-speed steel wire, improving the smoothness, and at the same time being able to remove impurities such as residual iron filings on the surface of the thin high-speed steel wire, facilitating the improvement of the quality of the thin high-speed steel wire. The blower 250 and the heating wire 260 are simultaneously turned on and energized, so that the blower 250 drives the fan blade 251 to rotate, and the blower 250 generates flowing air inside the drying cylinder 200, taking the heat generated by the heating wire 260, thereby accelerating the adsorption of the zinc-aluminum alloy solution adsorbed on the surface of the thin high-speed steel wire onto the surface of the thin high-speed steel wire, thereby improving the protective effect on the surface of the thin high-speed steel wire.
[0037] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
