Позицией 50 обозначен штампуемый материал, а позицией 51 - готовая деталь. 3050 denotes the stamped material, and 51 denotes the finished part. thirty

Устройство работает следующим образом.The device operates as follows.

Листовой рулонный материал 50 сматывается с барабана 15 и пропускается между подающими роликами 16, между боковыми ребрами ротора 6 и внутренней поверхностью корпуса 1, между направляющими роликами 20 и ножами летучих ножниц 21. Регулировкой приводов барабана 15 и направляющих ро- ₄₀ликов 20 создают требуемое натяжение обрабатываемого материала 50 так, что лента 50 плотно прилегает к боковой поверхности ротора 6. Включают насос 24 и карбюратор 25 заполняется ₄$ рабочей средой - смесью воздуха и топлива из бака 22. В полости 36 подают охлаждающую жидкость. При необходимости ребра 37 обдувают воздухом из вентилятора (не показан). На прерыватель 30 подают электрическое напряжение. От пускового электродвигателя (не показан) через эксцентриковый вал 9 ротор 6 приводится во вращение (по часовой стрелке).The sheet material roll 50 is unwound from drum 15 and passes between the feed rollers 16, between the side edges of the rotor 6 and the inner surface of the housing 1, between the guide rollers 20 and flying shear blades of the drum 21. By adjusting the actuators 15 and ₄₀ Po- guide faces 20 provide the desired tension processed material 50 so that the tape 50 fits snugly on the side surface of the rotor 6. Turn on the pump 24 and the carburetor 25 is filled with $ ₄ working medium - a mixture of air and fuel from the tank 22. Coolant is supplied to the cavity 36. If necessary, the fins 37 are blown with air from a fan (not shown). The breaker 30 is supplied with electrical voltage. From the starting motor (not shown) through the eccentric shaft 9, the rotor 6 is rotated (clockwise).

Карбюрированная рабочая смесь через канал 2 подается в камеру переменного объема, образованную внут ренней поверхностью корпуса 1, боковыми крышками 4 и 5 и наружной поверхностью обрабатываемого металла 50, охватывающего ротор 6.The carbured working mixture through the channel 2 is fed into a chamber of variable volume formed by the inner surface of the housing 1, side covers 4 and 5 and the outer surface of the metal to be treated 50, covering the rotor 6.

В месте расположения канала 2 при вращении ротора 6 по часовой стрелке объем рабочей камеры увеличивается и заполняется рабочей средой. Затем рабочая камера изолируется от канала 2,ее объем уменьшается и происходит процесс сжатия рабочей среды (процесс^ас на фиг.5 и 6). В конце процесса сжатия прерыватель 30 подает напряжение на свечу 29 зажигания и происходит воспламенение рабочей среды - начинается процесс сгорания (процесс Cz' на фиг.5 и 6). Продукты сгорания рабочей среды при давлении до 50 МПа и температуре порядка 1000°С осуществляют штамповку: материал 50 продавливается в матрицу 13 и в ней формируется деталь 51. Одновременно с продавливанием материала 50 в матрицу 13 кулачок 34 выступом наезжает на тарелку 41 штока 33, поршень 32 выдвигается из цилиндра 31 и внедряется в рабочую полость, вследствие чего процесс сгорания протекает изохорно, т.е. при постоянном объеме (линия сг' на фиг.5 вертикальна). Далее продукты сгорания расширяются в изоэнропном процессе (процесс z'b на фиг.5 и 6) и совершают работу, обеспечивающую самовращение как ротора 6, так и связанного с ним вала 49 с кулачком 34. При этом поршень 32 отжимается пружиной 40, утапливавается в цилиндр 31 и не препятствует вращению ротора 6, так как выступ кулачка 34 сходит с тарелки 41 штока 33. Затем продукты сгорания выпускаются через канал 26, фильтр-дожигатель 27 и глушитель 28 в атмосферу (процессЬа на фиг.5 и 6): термодинамический цикл замыкается.At the location of the channel 2, when the rotor 6 is rotated clockwise, the volume of the working chamber increases and is filled with the working medium. Then the working chamber is isolated from channel 2, its volume decreases and the process of compression of the working medium occurs (process ^ac in FIGS. 5 and 6). At the end of the compression process, the interrupter 30 supplies voltage to the spark plug 29 and ignition of the working medium occurs - the combustion process begins (process Cz 'in FIGS. 5 and 6). The products of combustion of the working medium at a pressure of up to 50 MPa and a temperature of the order of 1000 ° C are stamped: the material 50 is pressed into the matrix 13 and a part 51 is formed in it. At the same time as the material 50 is pressed into the matrix 13, the cam 34 protrudes on the plate 41 of the rod 33, the piston 32 is pushed out of the cylinder 31 and introduced into the working cavity, as a result of which the combustion process proceeds isochorically, i.e. at a constant volume (line cg 'in FIG. 5 is vertical). Next, the combustion products expand in an isoenropic process (process z'b in FIGS. 5 and 6) and perform work that ensures self-rotation of both the rotor 6 and the shaft 49 connected to it with the cam 34. In this case, the piston 32 is wrung out by the spring 40, is recessed into the cylinder 31 does not interfere with the rotation of the rotor 6, since the protrusion of the cam 34 leaves the plate 41 of the rod 33. Then, the combustion products are discharged through the channel 26, the filter afterburner 27 and the muffler 28 into the atmosphere (process 5a and 6): thermodynamic cycle closes.

Отштампованная лента 50 проходит через направляющие ролики 20 к летучим ножницам 21, они отрезают готовые детали 51, которые направляются в контейнер-накопитель (не показан).The stamped tape 50 passes through the guide rollers 20 to the flying scissors 21, they cut off the finished parts 51, which are sent to a storage container (not shown).

Обеспечение изохорности процесса сгорания рабочей среды при штамповке повышает внутренний КПД термодинамического цикла за счет увеличения среднецикловой температуры и давления (на фиг.5 и 6 выигрыш в полезной работе пропорционален заштрихованной площади) на 15-25%, благодаря чему снижается расход рабочей среды.Ensuring the isochorism of the process of combustion of the working medium during stamping increases the internal efficiency of the thermodynamic cycle by increasing the average cycle temperature and pressure (in Figs. 5 and 6, the gain in useful work is proportional to the hatched area) by 15-25%, thereby reducing the flow rate of the working medium.

The device works as follows. The sheet web material 50 is removed from the drum 5 and passed between the feed rollers 16, between the side edges of the rotor 6 and the inner surface of the housing 1, between the guide rollers 20 and the knives of the flying scissors 21. By adjusting the drives of the drum 15 and the guide rollers 20 they create the desired tension. The material 50 is being processed so that the belt 50 fits tightly against the side surface of the rotor 6. The pump 24 is turned on and the carburetor 25 is filled with a working medium — a mixture of air and fuel from the tank 22. Coolant 36 is fed into cavity 36. If necessary, the ribs 37 are blown with air from a fan (not shown). An electric voltage is applied to the interrupter 30. From the starting motor (not shown), through the eccentric shaft 9, the rotor 6 is rotated (clockwise). Through the channel 2, the carburized mixture is fed into the variable volume chamber formed by the inner surface of the housing 1, the side 4 and 5, and the outer surface of the metal 50 that surrounds the rotor 6. At the location of the channel 2 when the rotor 6 rotates clockwise, the volume of the 15 working chamber increases and is filled with working medium. Then, the working chamber is isolated from channel 2, its volume is enemax and the process of compression of the working medium occurs (procedure c in Figures 5 and 6). At the end of the compression process, the interrupter 30 applies voltage to the ignition plug 29 and the working medium ignites — the combustion process begins (process from g in Figures 5 and 6). The products of combustion of the working medium at pressures up to 50 Sh and temperature are on the order of stamping: material 50 is forced into matrix 13 and part 51 is formed in it.

In this case, the piston 32 is pressed by the spring 40, is inserted into the cylinder 31 and does not interfere with the rotation of the rotor 6, since the protrusion of the cam 34 comes off the plate 41 of the rod 33. Then the combustion products are discharged through the channel 26, the filter-burner 27 and the silencer 28 to the atmosphere (processa in FIGS. 5 and 6) : thermodynamic cycle closes.

Ensuring the isochoric process of burning the working medium during stamping increases the internal efficiency of the thermodynamic cycle by increasing the average cycle temperature and pressure (in Figures 5 and 6, the useful performance gain is proportional to the shaded area) by 15–25%, thereby reducing the consumption of the working medium.
