The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The embodiments of this utility model will be described below based on its overall structure.

[0034] Example 1

[0035] A spring steel wire production equipment with excellent winding and corrosion resistance, such as Figures 1-4 As shown, the system includes a water quenching tank 1.

The operator pulls the heat-conducting plate 13 upwards to remove the heat-conducting plate 13, heat dissipation fins 14, and cover plate 15 together. Then, the operator can pass the spring steel wire with excellent winding and corrosion resistance, which needs to be quenched, through the wire threader. After the wire threading is completed, the worker places the heat-conducting plate 13 back onto the top of the bracket 9.

Fans 12 are installed inside both the air inlet shroud 10 and the air outlet shroud 11. Multiple fans 12 and heat dissipation fins 14 are provided, and the multiple fans 12 and heat dissipation fins 14 are equidistantly distributed. An air duct is formed by the heat-conducting plate 13, the heat dissipation fins 14, and the cover plate 15. Water vapor rises after being generated and adheres to the bottom of the heat-conducting plate 13. Since both the heat-conducting plate 13 and the heat dissipation fins 14 are made of aluminum...

[0040] The implementation principle of the utility model is as follows: first, the staff pulls up the heat conduction plate 13 to disassemble the heat conduction plate 13, the heat dissipation fin 14 and the cover plate 15 together, then the staff can draw the spring steel wire with excellent winding and corrosion resistance to be quenched through the wire holder 8, after the wire drawing is completed, the staff puts the heat conduction plate 13 back to the top of the support 9, at this time, the plug-in plate 17 is inserted into the plug-in groove 16 to avoid the heat conduction plate 13, the heat dissipation fin 14 and the cover plate 15 from sliding randomly.

[0042] The air duct is formed by the heat-conducting plate 13, the heat-dissipating fins 14 and the cover plate 15, and the water vapor rises and adheres to the bottom of the heat-conducting plate 13 after being generated; since the heat-conducting plate 13 and the heat-dissipating fins 14 are both made of aluminum alloy, the heat-conducting plate 13 has good heat conductivity and can avoid water vapor corrosion; at this time, the fan 12 generates airflow, the airflow starts from the air inlet cover 10, passes through the gaps between the heat-conducting plates 13, the heat-dissipating fins 14 and the cover plate 15, enters the air outlet cover 11 and is discharged, thereby taking away the heat of the water vapor, making the water vapor recondense into water, and since the bottom of the heat-conducting plate 13 is inclined on both sides, the condensed water flows to the sides of the bracket 9 and then drips back into the water quenching tank 1, thereby avoiding the contact between the condensed water and the spring wire.
