The process for manufacturing the common carbon spring steel wire comprises the following steps: surface treatment, wire drawing and heat treatment. In order to improve the wire drawing process and obtain the carbon spring steel wire with smaller size, a larger total surface reduction rate and a smaller pass surface reduction rate of about 60 percent can be adopted to ensure the toughness of the product.

Detailed Description
The invention is further illustrated by the following examples in conjunction with the accompanying drawings:
the first embodiment is as follows: referring to fig. 1-2, a carbon spring steel wire multi-pass wire drawing device comprises a rack 2, a lubricating and cooling box 1-1, an inner wire winding wheel 4, a wire drawing mechanism 5, a driving mechanism, a heat exchange pipe 1-2, a cooling water tower 1-3, a first pipeline 1-4, a second pipeline 1-5, a variable frequency pump 1-6, a temperature sensor 1-7, a frequency converter and a controller.
The lubricating and cooling box 1-1 is fixedly arranged on the rack 2, a wire drawing working chamber 1-11 is arranged in the lubricating and cooling box 1-1, and a wire drawing lubricant N is filled in the wire drawing working chamber 1-11.

When the temperature sensor 1-7 detects that the temperature of the wiredrawing lubricant N in the lubricating and cooling tank 1-1 is not higher than the temperature threshold (such as 150 ℃), the controller can control the output voltage or/and frequency of the frequency converter 11 to be constant, and the driving motor of the frequency conversion pump 1-6 to work at a constant speed and maintain a constant and stable flow rate. Therefore, the maximum value of the N temperature of the wire drawing lubricant can be automatically controlled, the overtemperature can be prevented, and the torsion crack of the carbon spring steel wire caused by the strain aging of the steel wire during wire drawing can be prevented.
