(54) УСТРОЙСТВО ДЛЯ ПРАВКИ ПОЛОСЫ(54) DEVICE FOR EDITING STRIPS

1one

Изобретение относитс к металлеобработке и различным техническим процессам, используемым при восстановлении провода электрических машин и аппаратов.The invention relates to metalworking and various technical processes used in the recovery of the wire of electrical machines and apparatus.

Известно устройство дл правки полосы, содержащее установленные на станине подпружиненный перпендикул рно оси подачи полосы опорный башмак, размещенный на эксцентрике приводного вала, и .расположенный над баимаком ложемент, подпружиненный параллельно оси подачи полосы Г .There is a device for straightening a strip, which has a support shoe mounted on a frame that is spring-loaded perpendicularly to the strip feeding axis, located on the eccentric of the drive shaft, and a cradle that is spring-loaded above the baimuck and is spring-loaded parallel to the strip feeding axis G.

Недостатком этого устройства вл етс невысокое качество полосы.A disadvantage of this device is the low quality of the band.

Цель изобретени - повышение качества при обработке различных по сечению материалов.The purpose of the invention is to improve the quality when processing materials of different cross section.

Поставленна цель достигаетс тем что устройство снабжено двум смонтированными на приводном валу по обе стороны от баамака кулачками и двум шарнирно закрепленны ш на башмаке с противоположньах сторон от оси подачи полосы правильными элементами , подпружиненными относительно дру друга и взаимодействующими с кулачКё1МИ ,The goal is achieved by the fact that the device is equipped with two cams mounted on the drive shaft on both sides of the baamak and two articulated wedges on the shoe on opposite sides of the strip feed axis with regular elements, spring-loaded relative to each other and interacting with the camCy1MI,

На фиг, 1 изображено предлагаемое устройство , общий вид; на фиг. 2 разрез А-А на фиг, 1; на фиг, 3 вид Б на фиг 1 (ложемент условно не показан)на фиг. 4 - вид устройства в плане при разведенном положении правильных элементов(ложемент условно не показан),Fig, 1 shows the proposed device, a general view; in fig. 2 section A-A in FIG. 1; FIG. 3, view B in FIG. 1 (the lodgement is conventionally not shown) in FIG. 4 - view of the device in the plan when the correct elements are in the divorced position (the lodgement is conventionally not shown),

Устройство дл правки содержит установленный на станине в направл ющих 1 подпружиненный по ходу движе0 ни обрабатываемой полосы 2 ложемент 3 на роликах 4 и две опоры 5 приводного вала 6, На валу б жестко закреплены эксцентрик 7 и по обе стороны от эксцентрика - два кулачка 8,The dressing device contains mounted on the frame in the guides 1 spring-loaded along the movement of the treated strip 2, the lodgement 3 on the rollers 4 and the two supports 5 of the drive shaft 6, the eccentric 7 is rigidly fixed on the shaft b and two cams 8 on both sides of the eccentric are

На эксцентрик 7 посажен башмак 9, On the eccentric 7 put the shoe 9,

5 у которого сверху и спереди со стороны движени материала 2 имеетс прилив 10, а снизу - выемки дл пружин 11 сжати , установленных дл плавности работы устройства на станине. 5 which has a tide 10 on the top and front of the movement of the material 2, and on the bottom are recesses for compression springs 11 installed for smooth operation of the device on the frame.

Claims

0 In the tide of 10 shoes 9 pivotally on the axis 12 along the edges of the treated strip there are guide elements 13, the free ends of which are spring-loaded with a compression spring 14. In the middle part of the regular elements 13, the rollers 15 are installed above the drive shaft 6, interacting with the working surface B, The regular elements 13 are mounted on the shoe without the possibility of a skew in the straightening plane. To prevent the processed strip 2 from stretching, the speed of its passage through the device is synchronized with the angular speed of rotation of the drive shaft 6, and the gap between the working surfaces of the basement and the shoe in its upper position, as well as the distance between the working surfaces of the correct elements in their reduced cams 8 states are equal respectively to the width and thickness of the non-processed strip. When the drive shaft 6 is rotated, the strip is forced into the processing area in two mutually perpendicular planes by pressing it with the shoe 9 on the bed 3, and along the edges - by compressing the guide elements 13. Due to the offset processing of the strip on two mutually perpendicular planes, high device performance. High quality straightening is achieved so that when the shaft 6 rotates, all points of the working surface of the shoe 9 are made under the action of an eccentric 7 mounted on the shaft 6 in a circular motion, ensuring a smooth reduction of the strip to its nominal dimensions over the section between the shoe and the lodgment , and in the other plane Y ////// / 77 / L / // /////// 77 by smoothly compressing the strip with regular elements 13, driven by the cams 8. Since the lodgement 3 is set in the direction 1 on rollers 4 and spring-loaded along the movement of lane 2, wedging strip 2 between the bed entom shoe 3 and 9 in its upper state is possible. The invention of a strip straightening device comprising a support shoe mounted on a frame spring-loaded perpendicular to the feed axis of the strip, placed on the eccentric of the drive shaft, and a cradle located above the shoe, spring-loaded parallel to the strip feeding axis, different from that of PT9 equipped with two cams mounted on the drive shaft on both sides of the shoe and two regular elements hinged on the shoe on opposite sides of the strip feed axis E, spring-loaded relative to one another and interacting with the cams.
