Изобретение относитс к деревообрабатывающему оборудованию и может быть использовано в деревообрабатывающей промыщленности .The invention relates to woodworking machinery and can be used in woodworking.
Известны способы повыщени точности распиловки на круглопильных станках 1 и 2.Known methods for improving the accuracy of sawing on circular saws 1 and 2.
Недостатком известных способов вл етс низка эффективность.A disadvantage of the known methods is low efficiency.
Цель изобретени - обеспечение нормативной точности и щероховатости поверхности распиловки при максимальной скорости подачи.The purpose of the invention is to provide regulatory accuracy and roughness of the sawing surface at the maximum feed rate.
Поставленна цель достигаетс тем, что лри отклонении диска пилы от плоскости вращени на величину, превышающую допустимую , снижают скорость вращени пилы до уменьшени отклонени пилы в пределах допустимой величины, причем отношение скорости подачи и скорости резани сохран ют посто нным.The goal is achieved by reducing the saw blade's deviation from the plane of rotation by an amount exceeding the allowable one, reducing the saw rotation speed to reduce the saw deviation within the allowable value, while the ratio of the feed speed and cutting speed is kept constant.
Пример. Пила диаметром 500 мм, толщиной 2,2 мм, установлена на ребровом станке. Распиливаютс сосновые пиломатериалы высотой ЮО мм. Начальна скорость подачи 30 м/мин, частота вращени пилы 2000 об/мин. Критическа частота вращени пилы 3200 об/мин. У выхода пилы из пролила против периферийной зоны диска установлен датчик, регистрирующий отклонени диска. Нормативна точность распиловки характеризуетс предельными отклонени ми +1 мм. Датчик настроен так,Example. Saw with a diameter of 500 mm, 2.2 mm thick, mounted on a rib machine. Pine sawn timber with a height of 100 mm is cut. The initial feed rate is 30 m / min, the blade rotation speed is 2000 rpm. Critical frequency of rotation of the saw 3200 rpm. A sensor is installed at the exit of the saw from the spill against the peripheral zone of the disk, which detects disc deviations. The standard accuracy of sawing is characterized by a maximum deviation of +1 mm. The sensor is configured so
что при отклонени х свыще + 0,9 мм он посылает сигнал на регулирование (уменьшение ) частоты отклонени пилы до +0,5 мм шение) частоты вращени привода пилы и Привода подачи. При уменьшении отклонени пилы до + 0,5 мм частота вращени that with deviations above + 0.9 mm, it sends a signal to regulate (decrease) the frequency of the saw deviation to +0.5 mm seeding) the frequency of rotation of the saw drive and the feed drive. When reducing the saw deflection to + 0.5 mm, the rotational speed
приводов пилы и подачи повышаетс . В начальный момент пилени (при отсутствии нагрева пилы) частота вращени пилы увеличиваетс до 3200 об/мин, а скорость подачи - до 48 м/мин. После непрерывной подачи пиломатериалов и стабилизации температурного перепада в диске пилы частота вращени снижаетс до 1600 об/.мин, а скорость подачи - до 24 м/мин. Точность пиломатериалов находитс в пределах + (0,5-0,9)ммsaw drive and feed increases. At the initial time of sawing (in the absence of heating of the saw), the frequency of rotation of the saw increases to 3200 rpm, and the feed speed to 48 m / min. After a continuous supply of sawn timber and stabilization of the temperature difference in the saw blade, the rotation speed decreases to 1600 rpm and the feed speed drops to 24 m / min. Lumber accuracy is within + (0.5-0.9) mm
Использование предлагаемого способа повышени точности распиловки на круглопильных станках позвол ет повысить надежность регулировани точности распиловки и шероховатости поверхности пропила; а также производительность круглопильного оборудовани при заданном качестве распиловки на 20-30%.The use of the proposed method for improving the accuracy of sawing on circular saws allows increasing the reliability of adjusting the accuracy of sawing and the surface roughness of the kerf; as well as the productivity of circular sawing equipment for a given sawing quality by 20-30%.
