Abstract
Изобретение относитс к механическому производству, в частности к пневмомолотам. Цель изобретени - повышение энергоемкости за счет увеличени энергии удара. Пневмомолот содержит сопр женные между собой корпус с бойком 3 и пневматический цилиндр 1 с поршнем-ударником 2 и ресивером. В корпусе выполнены выхлопные окна 19 дл стравливани воздуха из предбойковой полости 21 в атмосферу. Суммарна площадь выхлопных окон равна площади поперечного сечени поршн -ударника 2. При увеличении давлени в полости ресивера поршень-ударник перемещаетс по направлению к бойку 3. Втулка сдвигаетс и открывает выхлопные окна 19, через которые воздух свободно вытесн етс из предбойковой полости без дросселировани . Тем самым исключаетс преп тствие перемещению поршн -ударника. 6 ил.The invention relates to mechanical production, in particular to pneumatic hammers. The purpose of the invention is to increase energy intensity by increasing the impact energy. The pneumatic hammer contains a housing interconnected with a striker 3 and a pneumatic cylinder 1 with a piston-hammer 2 and a receiver. In the casing, exhaust ports 19 are made to vent air from the pre-cavity 21 into the atmosphere. The total area of the exhaust ports is equal to the cross-sectional area of the piston of the impactor 2. As the pressure in the cavity of the receiver increases, the impacting piston moves towards the striker 3. The sleeve moves and opens the exhaust openings 19, through which air is freely expelled from the casing without throttling. Thereby preventing the movement of the impact piston. 6 Il.
