Description
Изобретение может найти применение дл зачистки прессованных изделий, например проволоки, прутков или труб.The invention may find use for stripping pressed articles, such as wire, rods or pipes.
Известны способы подобного назначени , когда зачищаемые заготовки перемещаютс поступательно через вращающуюс резцовую головку.Methods are known for this purpose when the blanks to be scraped are moved progressively through a rotating cutting tool.
Недостатком этих способов вл етс то, что при каждом пуске скорость резани должна измен тьс от нул до номинального значени . Возникающее при этом большое давление резани на инструмент приводит к поломке его режущих кромок.The disadvantage of these methods is that at every start-up, the cutting speed must change from zero to the nominal value. The resulting high cutting pressure on the tool leads to breakage of its cutting edges.
Чтобы устранить эти недостатки, в процессе обработки окружную скорость резцов непрерывно снижают, а скорость подачи издели бесступенчато повышают.To eliminate these disadvantages, during processing, the peripheral speed of the cutters is continuously reduced, and the feed rate of the product is continuously increased.
На фиг. 1 показана схема взаимодействи резцов и заготовки в начале обработки; на фиг. 2 - то же, в конце обработки.FIG. 1 shows the interaction between the incisors and the workpiece at the beginning of processing; in fig. 2 - the same at the end of processing.
В начале обработки ножева головка проводитс во вращение с максимальным числом оборотов так, чтобы резцы 1 вращались с высокой окружной скоростью (показана вектором 2). Одновременно зачищаемый материал 3 проходит через резцовую головку по направлению стрелки 4 с малой скоростью подачи, показанной на фиг. 1 вектором 5, при этом возникает скорость резани , изображенна на фиг. 1 вектором 6. Направление вектора скорости резани в начале обработки приближаетс к направлению радиуса режущей головки .At the beginning of machining, the knife head is rotated at a maximum number of revolutions so that the cutters 1 rotate at a high peripheral speed (shown by vector 2). At the same time, the scraped material 3 passes through the cutting head in the direction of arrow 4 at a low feed rate shown in FIG. 1 by vector 5, and a cutting speed is produced, as shown in FIG. 1 by the vector 6. The direction of the cutting speed vector at the start of machining approaches the direction of the radius of the cutting head.
В течение периода запуска скорость подачи издели непрерывно увеличивают, в то врем , 5 как посредством какого-либо известного в технике управл ющего устройства окружную скорость резцов измен ют таким образом, чтобы скорость резани хот бы и сохран лась по своей величине, но приближалась по направлению к направлению прохождени зачищаемого материала.During the start-up period, the feed rate of the product is continuously increased, while, 5, by means of a control device known in the art, the peripheral speed of the cutters is changed so that the cutting speed is at least maintained in its magnitude, but approaches in the direction of to the direction of passage of the cleaned material.
В течение процесса обработки окружна скорость резцов, показанна вектором 2, имеет такую величину, чтобы обеспечивалось не5 рекрытие режущих кромок. Скорость подачи издели достигает своего максимального значени и примерно соответствует по величине скорости резани ;.During the machining process, the circumferential speed of the incisors, shown by vector 2, is of such magnitude as to ensure some 5 cutting of the cutting edges. The product feed rate reaches its maximum value and approximately corresponds to the magnitude of the cutting speed;
Направление векторов 6 скорости резани 0 теперь примерно соответствует направлению вектора 4, изображающего подачу.The direction of the cutting velocity vectors 6 is now approximately the direction of vector 4, representing the feed.
Нредмет изобретени Nredmet of the invention
Способ зачистки изделий, например прово5 локи, прутков или труб вращающейс резцовой головкой при продольном перемещении издели , отличающийс тем, что, с целью предотвращени поломок инструмента, в процессе обработки окружную скорость рез0 цов непрерывно снижают, а скорость подачи издели бесступенчато повышают.A method of stripping products, such as wire, rods, rods, or tubes with a rotating cutting head during longitudinal movement of the product, characterized in that, in order to prevent tool breakage, during processing, the circumferential speed of the cutters is continuously reduced and the product feed rate is continuously increased.
