Technical Field

The utility model belongs to the field of special metallurgical manufacturing, and relates to a device for a cold-drawn bar lubrication process.

Background

In order to obtain better mechanical properties and higher-precision dimensions, the hot rolled bar needs to be subjected to cold drawing (cold drawing), namely, under the action of a pulling force, the bar passes through a die with gradually reduced diameter, so that the bar is subjected to plastic deformation, the internal crystal lattice of the bar slides, the tensile strength is greatly improved, the plasticity is reduced, and the hardness is improved.

In order to smooth and stabilize the cold drawing process and avoid cracks on the surface of the bar during the cold drawing process, the surface of the bar needs to be lubricated before cold drawing. One of the ways of lubrication is to submerge the rod in a lubricant using a surface to create a carrier carrying the lubrication factor.

The lubricant needs to be heated to a temperature to produce the best effect, e.g. a certain brand of lubricant requires that it be heated to 40 to 60 ℃ for use. The use temperatures of different brands have different requirements, the bars made of different materials have different soaking time and temperature requirements, and the temperature is difficult to control during manual operation in the prior art. In addition, to ensure uniformity of properties of the same batch and the same bar, uniformity of lubricant temperature needs to be ensured.

Meanwhile, the existing lubricating process for the surface of the bar is low in automation degree, more in manual operation, low in working efficiency and high in labor cost.
