Embodiment Construction

[0039] The device shown in the drawing for coating scaled deformed parts 1 contains a (only partly shown) pressure chamber 2 which is filled with a solid lubricant 3 under pressure P. FIG. This device is arranged on a drawing machine, not shown in the figures, before the drawing section for the deformation. The deformation part 1 is drawn in the drawing direction Z by means of the device. At the outlet of the pressure chamber 2 is arranged a drawing die 4 with which the deformation part 1 is deformed with a degree of deformation of ε=5%. In this case, the scale flakes 5 located on the deformed part 1 are broken into small scale particles and separated from the metal matrix of the deformed part. Together with the lubricant on the deformed part 1, the oxide scale particles are conveyed into the subsequently arranged accumulator element 6, which has a cylindrically running wire channel 7 whose inner diameter is 0.04 mm larger than that of the deformed part. Intense mixing of sc...

Abstract

The object of the present invention is to develop a method and a device by which scaled metal rod-shaped deformations (1) can be coated with a solid lubricant (3) for use in downstream drawing processes Avoid removing existing scale layers or solid layers containing scale from metal deformed parts while the deformation process is in progress. At the same time the precondition of substantially improving the stability of the downstream drawing process and the quality of the manufactured product should be met. In the method according to the invention, the scaled deformed part (1) is coated with a solid lubricant (3) prior to the downstream drawing process and deformed with a degree of deformation of more than 3%, and thereafter passed through at least An accumulation chamber ( 6 ) is drawn in order to mix the scale particles formed from the scale layer as a result of the deformation process with the lubricant present on the deformed part after the deformation process.

Description

technical field [0001] The invention relates to the field of metallurgy and relates to a method and a device for coating bar-shaped deformations of scaled metal with a lubricant for deformation in a downstream drawing process. Background technique [0002] When deforming scaled metal rod-shaped deformation parts, a prior cleaning process of the deformation part, commonly referred to as wire rod, plays a decisive role. It is generally known to cover wire rods with oxide layers, hydroxide layers, scale layers or the like. These surface layers, which are especially caused by the thermal deformation process, have to be carefully removed before drawing, because their presence not only leads to significantly higher wear of the drawing tool and a significant reduction in the possible drawing speed , but also cause a strong quality degradation of the wire to be drawn. In many cases deformation processes under such conditions are not even feasible at all. [0003] For the removal ...
