Известен способ снижени идума на деревообрабатывающих станках, путем закрыти нерабочей зоны вращающегос режущего инструмента приемником и создани вокруг него воздущпого потока.There is a known method of reducing idling on woodworking machines by closing the non-working zone of a rotating cutting tool with a receiver and creating an air flow around it.
Цель изобретени - улучщить услови труда .The purpose of the invention is to improve the working conditions.
Достигаетс это тем, что воздущный поток подают со скоростью, равной окружной скорости инструмента.This is achieved by the fact that the air flow is supplied with a speed equal to the peripheral speed of the tool.
Дл этого нерабочую зону режущего инструмента закрывают приемником, который подключают к сети эксгаустерной установки. Напор в сети эксгаустерной установки и сечепие приемника устанавливают таким, чтобы скорость воздушного потока, движущегос в приемнике вокруг режущего инструмента, была равной окружной скорости вращающегос инструмента . При выполнении этого услови скорость обтекани фрезы воздушным потоком будет равной нулю. Давление в пазухе, образованной передней гранью зуба и корпусом фрезы, тоже будет равным нулю. В таких услови х фреза не может создавать вихри в воздушном потоке. Все это приводит к снижению вихревого аэродинамического щума.For this, the non-working area of the cutting tool is covered by a receiver that is connected to the network of the exhauster unit. The pressure in the network of the exhauster unit and the receiver section are set such that the speed of the air flow moving in the receiver around the cutting tool is equal to the peripheral speed of the rotating tool. When this condition is met, the airflow around the cutter will be zero. The pressure in the sinus formed by the front face of the tooth and the body of the cutter will also be equal to zero. Under these conditions, the milling cutter cannot create eddies in the air flow. All this leads to a decrease in the vortex aerodynamic sound.
