Description

Technical Field

[0001] This utility model relates to the technical field of electrical discharge texturing gap control devices, specifically, to an electrical discharge texturing gap control device for the work rolls of a finishing machine. Background Technology

[0002] Electrical discharge machining (EDM) texturing of work rolls in finishing mills is a process that utilizes the principle of electrical discharge machining to texturize the surface of work rolls, creating a surface roughness to a specific degree. The basic principle involves immersing the electrode and work roll together in a working fluid such as insulating oil. A generator unit applies a pulsed voltage to the electrode and roll. When the gap between the electrode and roll surfaces decreases to 0.02mm-0.002mm, a discharge channel is created at the gap. The electrical energy generated by the discharge causes the localized metal on the roll surface to melt or even vaporize instantaneously. The bursting of the vaporized bubbles ejects the molten metal, which is carried away by the working fluid, thus forming discharge pits on the roll surface, achieving texturing.

[0003] The EDM texturing gap control device for the work roll of the finishing machine is a component used to precisely regulate the discharge gap between the electrode and the work roll to ensure stable and high-quality texturing processing.

[0004] In the prior art, the control of the texturing gap in electrical discharge machining mainly involves placing the work roll on top of the texturing chamber and driving the work roll to rotate. At the same time, the position of the electrode is adjusted by mechanical rigidity adjustment, thereby adjusting the gap between the electrode and the work roll. However, the work roll is easily affected by external forces and shakes during its rotation on the surface of the texturing chamber, which in turn affects the gap between the work roll and the electrode.
