Description

Изобретение относитс  к обработке строительных материалов, в частности к инструментам дл  комбинированной обработки путем резани  и скалывани .The invention relates to the processing of building materials, in particular to tools for combined processing by cutting and chipping.

Целью изобретени   вл етс  улучшение качества обрабатываемой поверхности.The aim of the invention is to improve the quality of the treated surface.

На чертеже изображен инструмент, общий Вид, со схемой обработки.The drawing shows the tool, a General View, with a processing scheme.

Инструмент состоит из режущего диска 1 и установленного соосно с ним скалывател  2. Угол наклона образующей рабочей поверхности скалывател  а имеет переменное значение, которое плавно симметрично возрастает в противоположные стороны от одного конца диаметра D к другому.The tool consists of a cutting disc 1 and a cleaver 2 installed coaxially with it. The angle of inclination of the generator of the working surface of the cleaver a has a variable value that smoothly symmetrically increases in opposite directions from one end of the diameter D to the other.

Инструмент работает следующим образом .The tool works as follows.

Обрабатываемый материал 3 под действием усили  подачи стола 4 подаетс  на вращающийс  с заданной скоростью режущий диск 1, который прорезает в материале 3 щель. По мере подачи обрабатываемого материала на режущий диск 1 длина щели увеличиваетс  и кромка материала приходит в соприкосновение со скалывателем 2. За счет измен ющегос  (переменного) значени  угла наклона образующей рабочей поверхности скалывател  происходит постепенное расшатывание отдел емой части материала. При этом в зоне А образуютс  микротрещины,The material to be processed 3 is fed by the force of supplying the table 4 to a cutting disk 1 rotating at a predetermined speed, which cuts a slit in the material 3. As the processed material is fed to the cutting disk 1, the slot length increases and the material edge comes in contact with the cleaver 2. Due to the changing (variable) value of the angle of inclination of the working surface of the cleaver, the separated part of the material is gradually loosened. In this case, microcracks are formed in zone A,

которые развиваютс  в макротрещины, далее в глобальные трещины, и наступает момент, когда отдел ема  часть материала отваливаетс . Здесь максимальный импульс в момент скола отсутствует.which develop into macrocracks, further into global cracks, and there comes a moment when the separated part of the material falls off. Here, the maximum impulse at the moment of cleaving is absent.

Таким образом, незначительное скалывающее усилие имеет место только в начальный момент контакта скалывател  с материалом с последующим плавным убыванием , что оказывает значительное вли ние на качество обработанной поверхности .Thus, a slight shearing force takes place only at the initial moment of contact of the cleaver with the material, followed by a smooth decrease, which has a significant effect on the quality of the treated surface.
