' *Also known installation for breaking bars on measured billets, containing retractable beam, carrying scraptel4, base, support, clamp clamp mechanism, knife mounted on the base. '*

Недостатком этой установки является сложность ее Конструкции, а также и то, что точное совмещение плоскости надреза с осью опоры затруднено, так 25 как надрез осуществляется на некотором расстоянии от опоры и затем прокат перемещают до совпадения плоскости надреза с осью опоры. Несовпадение плоскости надреза с осью опоры при- · 30 водит к снижению качества получаемых заготовок. Кроме этого, при ломке проката на известном устройстве получаются концевые отходы, длина которых превышает длину заготовки, так как механизм зажима расположен на расстоянии от опоры, превышающем длину мерной получаемой заготовки.The disadvantage of this installation is the complexity of its design, as well as the fact that the exact alignment of the notch plane with the axis of the support is difficult, since 25 the notch is carried out at a certain distance from the support and then the rolling is moved until the notch plane coincides with the axis of the support. The mismatch of the notch plane with the axis of the support leads to a decrease in the quality of the obtained workpieces. In addition, when breaking the rolled products on the known device, end waste is obtained, the length of which exceeds the length of the workpiece, since the clamping mechanism is located at a distance from the support exceeding the length of the measured obtained workpiece.

_п Цель изобретения — упрощение конструкции, повышение качества получаемых заготовок за счет обеспечения точного совмещения надреза с осью опоры, а также уменьшение концевых отходов.The purpose of the invention _n - simplification of the design, enhancing the quality of the preforms by providing precise alignment of the notch with the axis of the support, as well as reducing waste end.

С этой целью механизм зажима и над 15 резки выполнен в виде корпуса с отверстием и'рычага, шарнирно установленного в нем, а нож закреплен на конце рычага соосно с опорой.To this end, the clamping mechanism and over 15 cutting is made in the form of a housing with a hole and a lever pivotally mounted in it, and the knife is fixed at the end of the lever coaxially with the support.

Свободный, проход' проката отверстий 7 корпуса 6 обеспечивается благодаря тому, что расстояние между нижней поверхностью отверстия 7 и рабочей поверхностью 12 jq рычага 8 превышает (незначительно) диаметр проката 13. Затем перемещением траверсы 1 силового устройства ломатель 2 нажимает на консольно выдвинутую часть проката. Прокат 13, __ стремясь под действием нагрузки опро- кинуться на опоре 4, надавливает на· рычаг 8, который благодаря наличию скоса 11, начинает поворачиваться, и клиновой нож дополнительно зажимает пруток и врезается в него, производя 30 надрез, точно расположенный над осью опоры 4. В Определенный момент перемещения ломателя 2 вниз происходит отделение заготовки, падающей на склиз 16. После этого траверса 1 с ломателем 2 поднимаются вверх (в исходное положение), а рычаг 8, поворачиваясь на оси 9, благодаря тому, что вес левой его части меньше правой, также возвращается в исходное положение . Установка готова к совершению очередного цикла.Rolled 13 roller table 14 is fed to the stop 15, set to size 15 of the length of the detachable workpieces. The free passage of the rolled holes 7 of the housing 6 is ensured by the fact that the distance between the lower surface of the hole 7 and the working surface 12 jq of the lever 8 exceeds (slightly) the diameter of the rolled 13. Then, by moving the beam 1 of the power device, the breaker 2 presses the console extended part of the rolled. Rolling 13, __ tending to fall over the support 4 under the action of the load, presses on the lever 8, which, due to the presence of the bevel 11, starts to turn, and the wedge knife additionally clamps the bar and cuts into it, making a 30 cut, exactly located above the axis of the support 4. At a certain moment of moving the breaker 2 downward, the workpiece falling on the slope 16 is separated. After this, the crosshead 1 with the breaker 2 rise up (to the initial position), and the lever 8, turning on the axis 9, due to the weight of its left part smaller right also e returns to its original position. Installation is ready for the next cycle.
