Abstract

The invention relates to the technical field of groove profile rolling, in particular to an ultrasonic and pulse current mixing auxiliary wedge-shaped cavity profile rolling line and a rolling process. The ultrasonic and pulse current mixing auxiliary wedge-shaped cavity profile rolling line is characterized in that a left horizontal alignment roller, a pre-rolling roller, a left ultrasonic vibration roller, a left electric brush, a roller set, a right electric brush, a right ultrasonic vibration roller, a right height alignment roller and a right horizontal alignment carrier roller are sequentially arranged along the rolling line, the left horizontal alignment roller and a right horizontal alignment roller are composed of a left roller and a right roller which are horizontally arranged, the pre-rolling roller and the right height alignment roller are composed of an upper roller and a lower roller which are vertically arranged, the left ultrasonic vibration roller and a right ultrasonic vibration roller are composed of an upper roller and a lower roller which are vertically arranged, and the roller set is composed of an upper roller and a lower roller which are vertical arranged; the ultrasonic vibration module is connected with the left ultrasonic vibration roller and the right ultrasonic vibration roller, and drives the left ultrasonic vibration roller and the right ultrasonic vibration roller to vibrate ultrasonically; and the left electric brush and the right electric brush are connected with a pulse current source. The rolling difficulty of a wedge-shaped cavity profile is reduced, the rolling efficiency is improved, and the size precision and the surface finish of the wedge-shaped cavity profile are improved.

Description

technical field [0001] The invention relates to the technical field of groove profile rolling, in particular to an ultrasonic wave and pulse current mixed-assisted wedge-shaped cavity profile rolling line and a rolling process. Background technique [0002] The available preparation processes for thin-necked wedge-shaped cavity profiles made of metal mainly include cold / warm / hot extrusion molding, cold / warm / hot drawing, milling, and wire EDM. Common thin-necked wedge cavity profiles made of metal are mainly made of metal materials with low yield strength and low deformation resistance, such as aluminum alloy, copper alloy and low carbon steel. This kind of narrow-necked wedge-shaped cavity profile is mainly prepared by cold / warm / hot extrusion or cold / warm / hot drawing. However, if a thin-necked wedge-shaped cavity made of metal material with high yield strength, deformation resistance and hardness, and low forming strain limit is prepared, there will be excessive wear of the...

Problems solved by technology

Under the condition of fluid / liquid with lubricating and cooling functions on the surface of the blank strip during the rolling of the blank strip, if the liquid / fluid has low resistivity and poor contact, this usually leads to deterioration of the insulation performance of the energized system, Improve the insulation difficulty of the system, and the continuous electric field excitation in the energized state will also affect the stability of the fluid / liquid chemical composition and the stability of the physical function of the lubricating and cooling functions; on the other hand, if the liquid / fluid resistivity Higher, which will inevitably increase the total contact resistance of the surface of the roll and the blank strip material, degrade the electrification efficiency and effect, increase the calorific value and temperature rise of the contact surface between the blank strip material, the roll and the forming profile, and increase the roll and The risk of thermal load, thermal deformation and corrosion of blank strips increases the energy loss of power-on
