Problems solved by technology

[0003] For this reason, first, there must be good lubrication and sufficient cooling during wire drawing; second, if a smaller pass area reduction rate is used, multi-pass drawing, each deformation is small, and the speed of each drawing mechanism is required to be constant. Waiting and increasing sequentially, there is a problem that it is difficult to realize; thirdly, if the wire drawing speed is reduced, although it helps to reduce the temperature rise of the steel wire, there is a problem of low wire feeding speed and slow production efficiency.

Abstract

The invention discloses a wire drawing and lubrication cooling device for a carbon spring steel wire. The wire drawing and lubrication cooling device is characterized by comprising a lubrication cooling box, a heat exchange tube, a cooling water tower, a first pipeline, a second pipeline, a frequency-variable pump, a temperature sensor, a transducer and a controller, the lubrication cooling box isinternally provided with a wire drawing working chamber, a wire drawing lubrication agent is loaded in the wire drawing working chamber, the heat exchange tube is located in the lubrication cooling box, the cooling water tower comprises a tower body, a water spraying assembly and a filtration layer, the temperature sensor is arranged in the lubrication cooling box and used for the real-time detection of the temperature of the wire drawing lubrication agent, the temperature sensor is electrically connected to the controller, and the controller, the transducer and the frequency-variable pump are electrically connected in sequence. The wire drawing and lubrication cooling device can be used for lubrication and adequate cooling control during wire drawing, and the temperature of the steel wire is prevented from being raised during wire drawing so as to avoid the twisting crack due to the strain aging produced by the carbon spring steel wire. The invention further discloses a wire drawingproduction line.

Description

technical field [0001] The invention belongs to the technical field of carbon spring steel wire production equipment, and in particular relates to a carbon spring steel wire drawing lubricating cooling device and a drawing production line. Background technique [0002] Commonly used carbon spring steel wire manufacturing methods include: surface treatment, wire drawing, heat treatment. In order to improve the drawing process and obtain carbon spring steel wire of smaller size, a larger total area reduction rate of about 60% and a smaller pass area reduction rate can be used to ensure the toughness of the product. For carbon spring steel wire, the outlet temperature of each pass of the steel wire should be controlled below 150°C during drawing to prevent torsional cracks in the steel wire due to strain aging, which is the main defect that causes the steel wire to be scrapped. [0003] For this reason, first, there must be good lubrication and sufficient cooling during wire d...
