ДИСКОВАЯПИЛАДЛЯРЕЗКИПРОКАТА DISC SAWS FOR CUTTING
Область примененияApplication area
Изобретение относится к прокатному производству, а точнее к устройствам для разделения проката на мерные длины.The invention relates to rolling production, and more specifically to devices for dividing rolled products into measured lengths.
Предшествующий уровень техникиState of the art
Известна пила для резки проката, содержащая станину и установленный на ней механизм возвратно-поступательного перемещения протяжки с выполненными на ней под углом к горизонтали рядом зубьев (см. авторское свидетельство SU JVs 127555, кл. B23D43/02, 01.01.1960).Known saw for cutting, containing a frame and mounted on it a mechanism for reciprocating movement of the broach with a number of teeth made on it at an angle to the horizontal (see copyright certificate SU JVs 127555, class B23D43 / 02, 01.01.1960).
Однако данная конструкция пилы имеет большую металлоемкость из-за необходимости выполнения протяжки большой длины.However, this design of the saw has a large metal consumption due to the need to perform broaching long lengths.
Наиболее близкой к изобретению по решаемой задаче и достигаемому техническому результату является дисковая пила для резки проката, содержащая станину и установленные на ней механизм возвратно-поступательного перемещения пильного диска и привод вращения пильного диска (см. авторское свидетельство SU JMs 132042, кл. B23D47/02, 1960.01.01). В данной дисковой пиле для резки проката производится непрерывная подача пильного диска в разрезаемый прокат, что приводит к образованию длинных и тонких стружек, которые трудно удаляются из разрезаемого материала. Зубья пилы испытывают большое трение, что с учетом высокой скорости вращения пильного диска приводит к преждевременному его выходу из строя. Кроме того, при резке в виду большой скорости вращения пильный диск испытывает большое сопротивление, что снижает скорость его подачи и, как следствие, приводит к увеличению времени, которое необходимо для разрезания проката на мерные длины.Closest to the invention in terms of the problem to be solved and the technical result achieved is a circular saw for cutting, containing a bed and a mechanism for reciprocating movement of the saw blade and a drive for rotating the saw blade mounted on it (see copyright certificate SU JMs 132042, class B23D47 / 02 , 1960.01.01). In this circular saw for cutting rolled products, the saw blade is continuously fed into the cut steel, which leads to the formation of long and thin shavings that are difficult to remove from the cut material. The saw teeth experience a lot of friction, which, given the high speed of rotation of the saw blade, leads to its premature failure. In addition, when cutting due to the high speed of rotation, the saw blade experiences a lot of resistance, which reduces its feed rate and, as a result, leads to an increase in the time required to cut the rolled product into measured lengths.
Раскрытие изобретенияDisclosure of invention
Задачей, на решение которой направлено настоящее изобретение, является увеличение подачи пильного диска в разрезаемый прокат и снижение трения при резке проката.The problem to which the present invention is directed, is to increase the feed of the saw blade to cut steel and reduce friction when cutting steel.
Техническим результатом, достигаемым при реализации изобретения, является повышение производительности при резке проката и уменьшение износа пильного диска. Указанная задача решается, а технический результат достигается за счет того, что дисковая пила для резки проката содержит станину и установленные на ней механизм возвратно-поступательного перемещения пильного диска и привод вращения пильного диска, при этом станина снабжена зажимным устройством для фиксации разрезаемого проката, а механизм возвратно-поступательного перемещения пильного диска выполнен с возможностью прерывистой подачи пильного диска для периодического вдавливания зубьев пильного диска в разрезаемый прокат в виде гидроцилиндра, подключенного последовательно через гидрораспределитель и сервопривод к маслонасосу, который вместе с приводным электродвигателем размещен на маслобаке.The technical result achieved by the implementation of the invention is to increase productivity when cutting steel and reduce wear of the saw blade. This problem is solved, and the technical result is achieved due to the fact that the circular saw for cutting rolled products contains a bed and a mechanism for reciprocating movement of the saw blade and a drive for rotating the saw blade mounted on it, while the bed is equipped with a clamping device for fixing the cut steel, and the mechanism reciprocating movement of the saw blade is made with the possibility of intermittent feed of the saw blade for periodic indentation of the teeth of the saw blade in the cut steel in the form of a cylinder, connected in series through a hydraulic distributor and a servo drive to the oil pump, which, together with a drive motor, is located on the oil tank.
В ходе проведенного исследования было выявлено, что можно резко повысить производительность дисковой пилы при резке проката за счет снабжения дисковой пилы механизмом прерывистой подачи пильного диска в разрезаемый прокат. При этом было установлено, что наиболее предпочтительно, чтобы время между прерывистыми подачами пильного диска в разрезаемый прокат было равно времени поворота пильного диска, за которое вершины зубьев пильного диска пройдут расстояние, равное расстоянию между вершинами соседних зубьев пильного диска плюс 1-5 мм. Это связано с тем, что при прерывистой подаче пильного диска срезаемый материал остается в пространстве между зубьями пильного диска и величина стружки, образуемой при каждом углублении зуба пильного диска в металл, а точнее ее длина будет составлять длину пути, который проходит каждый зуб пильного диска после его углубления в металл разрезаемого проката. Учитывая неточность поворота пильного диска и необходимость перекрытия для срезания образовавшейся в результате надреза металла стружки, величину поворота пильного диска увеличивают в зависимости от диаметра пильного диска на 1-5 мм.In the course of the study, it was found that it is possible to sharply increase the performance of a circular saw during cutting by supplying a circular saw with a mechanism for intermittent feeding of a circular saw blade to cut steel. It was found that it is most preferable that the time between intermittent feeds of the saw blade into cut steel be equal to the time of rotation of the saw blade, over which the tops of the teeth of the saw blade will cover a distance equal to the distance between the vertices of the adjacent teeth of the saw blade plus 1-5 mm. This is due to the fact that during intermittent feeding of the saw blade, the material to be cut remains in the space between the teeth of the saw blade and the amount of chips formed at each recess of the tooth of the saw blade into the metal, or rather its length will be the length of the path that each tooth of the saw blade passes after its recesses in the metal of the rolled metal. Given the inaccuracy of the rotation of the saw blade and the need for overlapping to cut off the chips formed as a result of the metal notch, the rotation of the saw blade is increased by 1-5 mm depending on the diameter of the saw blade.

На фиг.l представлена схематически дисковая пила для резки проката.Figure l shows a schematic diagram of a circular saw for cutting.
Лучший вариант осуществления изобретения Дисковая пила для резки проката содержит станину 1 и установленные на ней механизм 2 возвратно-поступательного перемещения пильного диска 3 в виде гидроцилиндра и привод вращения (не показан на чертеже) пильного диска 3. Механизм 2 возвратно- поступательного перемещения соединен с пильным диском 3 посредством суппорта 4. Станина 1 снабжена зажимным устройством 5 для фиксации разрезаемого проката 6. Механизм 2 возвратно- поступательного перемещения пильного диска 3 выполнен с возможностью прерывистой подачи пильного диска 3 для периодического вдавливания зубьев пильного диска 3 в разрезаемый прокат 6 в виде гидроцилиндра подключенного последовательно через гидрораспределитель 7 и сервопривод 8 к маслонасосу 9, который вместе с приводным электродвигателем 10 размещен на маслобаке 11.BEST MODE FOR CARRYING OUT THE INVENTION A circular saw for cutting rolled products comprises a frame 1 and a reciprocating mechanism 2 of the saw blade 3 in the form of a hydraulic cylinder and a rotation drive (not shown in the drawing) of the saw blade 3. The reciprocating mechanism 2 is connected to the saw the disk 3 by means of a support 4. The bed 1 is equipped with a clamping device 5 for fixing the cut hire 6. The mechanism 2 of the reciprocating movement of the saw blade 3 is made intermittently feeding the saw blade 3 for periodically pressing the teeth of the saw blade 3 into the cut steel 6 in the form of a hydraulic cylinder connected in series through a control valve 7 and a servo drive 8 to the oil pump 9, which together with a drive motor 10 is placed on the oil tank 11.
Посредством гидрораспределителя 7 меняют направление перемещения суппорта 4 с пильным диском 3 относительно разрезаемого проката 6, а посредством сервопривода 8 задают время, через которое происходит периодическое вдавливание зубьев 12 пильного диска 3 в разрезаемый прокат 6. С помощью маслонасоса 9 и гидроцилиндра создается требуемое усилие для вдавливания зубьев 12 пильного диска 3 в разрезаемый прокат 6.Using the valve 7, the direction of movement of the caliper 4 with the saw blade 3 relative to the cut steel 6 is changed, and by means of the servo drive 8, the time after which the teeth 12 of the saw blade 3 are periodically pressed into the cut steel 6 is set. Using the oil pump 9 and the hydraulic cylinder, the required pressure is created teeth 12 of the saw blade 3 in the cut steel 6.
Время между прерывистыми подачами пильного диска 3 в разрезаемый прокат 6 равно времени поворота пильного диска 3, за которое вершины зубьев 12 пильного диска 3 пройдут расстояние, равное расстоянию «k» между вершинами соседних зубьев 12 пильного диска плюс Δ = 1-5 мм.The time between intermittent feeds of the saw blade 3 into the cut steel 6 is equal to the rotation time of the saw blade 3, during which the vertices of the teeth 12 of the saw blade 3 will pass the distance equal to the distance "k" between the vertices of the adjacent teeth 12 of the saw blade plus Δ = 1-5 mm.
Разрезаемый прокат 6 фиксируют в зажимном устройстве 5. Пильный диск 3 подводят к разрезаемому прокату 6. Далее маслонасос 9 подает масло из бака 11 через сервопривод 8 и гидрораспределитель 7 в гидроцилиндр, причем посредством сервопривода 8 обеспечивают прерывистое перемещение пильного диска 3. При каждом перемещении пильного диска 3 его зубья вдавливаются в металл проката 6 на заданную глубину и затем эти зубья 12 во время поворота пильного диска 3 срезают металл проката 6, после чего при следующем вдавливании зубьев 12 в металл проката 6 зубья 12 пильного диска 3 обрезают образовавшуюся стружку, которая остается между зубьями 12 пильного диска 3 до момента выхода зубьев 12 из разрезаемого проката 6. После выхода зубьев 12 из разрезаемого проката 6 стружка в виде мелких чешуек высыпается из межзубного пространства. Промышленная применимостьThe cut steel 6 is fixed in the clamping device 5. The saw blade 3 is led to the cut steel 6. Next, the oil pump 9 delivers oil from the tank 11 through the actuator 8 and the control valve 7 to the hydraulic cylinder, and by means of the servodrive 8, the saw blade 3 is intermittently moved. Each time the saw blade is moved. the disk 3 its teeth are pressed into the rolled metal 6 to a predetermined depth and then these teeth 12 during the rotation of the saw blade 3 cut the rolled metal 6, after which the next pressing of the teeth 12 into the rolled metal 6 teeth 12 the saw blade 3 cut off the formed chips, which remains between the teeth 12 of the saw blade 3 until the teeth 12 exit the cut steel 6. After the teeth 12 exit the cut steel 6, the chips in the form of small flakes fall out of the interdental space. Industrial applicability
