Description

Изобретение относится к обработке материалов давлением, й частности к устройствам для ультразвуковой обработки материалов.The invention relates to the processing of materials by pressure, and in particular to devices for ultrasonic processing of materials.

Известно устройство для ультразвуковой прокатки материалов, включающее валки, излучатели ультразвуковых колебаний [1]. ^{5 * * * *} A device for ultrasonic rolling of materials is known, including rolls, emitters of ultrasonic vibrations [1]. ^{5 * * * *}

Недостатком известного устройства является большая потеря энергии.A disadvantage of the known device is a large loss of energy.

Цель изобретения — повышение эффективности передачи энергии ультразвуковых колебаний в зону деформации прокатываемого матери-^{10 * * * *}ала.The purpose of the invention is to increase the efficiency of energy transfer of ultrasonic vibrations to the deformation zone of the rolled material - ^{10 * * * *} ala.

Поставленная цель достигается тем, что излучатели предлагаемого устройства выполнены цилиндрическими и установлены внутри валков.This goal is achieved in that the emitters of the proposed device are cylindrical and installed inside the rolls.

На фиг. 1 изображено устройство, общий вид;¹⁵ на фиг. 2 — сечение А-А на фиг. 1.In FIG. 1 shows a device, a General view; ¹⁵ in FIG. 2 is a section AA in FIG. 1.

Внутри полых валков 1 запрессованы кольцевые магнитострикционные излучатели 2 с обмоткой 3. С торцов, излучатели 2 прижимаются опорными фланцами 4.Inside the hollow rolls 1, annular magnetostrictive emitters 2 with a winding 3 are pressed in. From the ends, the emitters 2 are pressed by the support flanges 4.

В процессе работы прокатываемый материал 5 пропускают через валки 1 с заданным зазором и скоростью, соответствующей времени ультразвуковой обработки, при этом ультразвуковые колебания подводятся : непосредственно в зону деформации, что позволит снизить усилие прокатки и равномерно распределить амплитуду колебаний по длине валка.In the process, the rolled material 5 is passed through the rolls 1 with a given gap and speed corresponding to the time of ultrasonic treatment, while the ultrasonic vibrations are fed directly to the deformation zone, which will reduce the rolling force and evenly distribute the vibration amplitude along the length of the roll.

Claims

The invention relates to the processing of materials by pressure, 6 particularly to devices for ultrasonic processing of materials. A device for ultrasonic rolling of materials is known, which includes rolls, emitters of ultrasonic vibrations. A disadvantage of the known device is a large loss of energy. The purpose of the invention is to increase the efficiency of energy transfer of ultrasonic vibrations to the deformation zone of the rolled material. This goal is achieved by the fact that the emitters of the proposed device are cylindrical and mounted inside the rolls. FIG. 1 shows the device, a general view; in fig. 2 is a section A-A in FIG. 1. Inside the hollow rolls 1, annular magnetostrictive emitters 2 are wound with a winding 3. From the ends, the emitters 2 are pressed by supporting flanges 4. During operation, the rolled material 5 is passed through the rolls 1 with a predetermined gap and a speed corresponding to the ultrasonic processing time, while the ultrasonic oscillations are supplied: directly into the deformation zone, which will reduce the rolling force and evenly distribute the amplitude of oscillations along the length of the roll. Apparatus of the invention for ultrasonic rolling of materials, including rolls and emitters of ultrasonic vibrations, characterized in that, in order to increase the efficiency of energy transfer of ultrasonic vibrations to the deformation zone of the rolled material, the emitters are cylindrical and mounted inside the rolls.
