Description
(54) СПОСОБ ОПРЕДЕЛЕНИЯ НАЧАЛА ПРЕССОВАНИЯ(54) METHOD FOR DETERMINING THE BEGINNING OF PRESSING
II
Изобретение относитс к обработке металлов давлением, а точнее к способам управлени гидропрессами дл прессовани с дроссельным управлением.The invention relates to the processing of metals by pressure, and more specifically to methods of controlling hydraulic presses for pressing with throttle control.
Известен способ, включающий с момента начала прессовки посто нное слежение за , давлением в рабочих цилиндрах пресса и скоростью перемещени пресс-щтемпел и подачу команды на начало прессовани 1.The known method includes, since the start of pressing, constant monitoring of the pressure in the working cylinders of the press and the speed of movement of the press shtamp and the command to start the pressing 1.
Недостатками этого способа вл етс невысока производительность процесса изза заниженных скоростей подпрессовки, fo осуществл емой через обводные клапаны, а также низкое качество изделий из-за инерционности дроссел .The disadvantages of this method are the low productivity of the process due to the lowered speeds of the pressing, fo carried out through bypass valves, as well as the low quality of the products due to the inertia of the throttles.
Цель изобретени - повышение производительности и качества изделий.The purpose of the invention is to increase the productivity and quality of products.
Поставленна цель достигаетс тем, что 15 осуществл ют посто нное определение отношени давлени в рабочих цилиндрах к скорости пресс-штемпел и по достижении этим отношением максимальной величины подают команду на начало прессовани .This goal is achieved by the fact that 15 carry out a constant determination of the ratio of pressure in the working cylinders to the speed of the ram, and when this ratio reaches the maximum value, the command to start the pressing is given.
Определение начала прессовани по пред- 20 лагаемому способу производ т с помощью устройства дл автоматического прессовани , содержащего датчик давлени , измерительThe determination of the start of pressing according to the proposed method is carried out using an automatic pressing device comprising a pressure sensor, a meter
скорости, решающее устройство и y3evT фиксации максимума отношени давлени и скорости . При этом выход датчика давлени соединен со входом узла фиксации максимума отнощени давлени и скорости, второй вход которого соединен с измерителем скорости, а выход присоединен ко входу рещающего устройства.speed, solver and y3evT fixing the maximum of the ratio of pressure and speed. At the same time, the output of the pressure sensor is connected to the input of the fixing unit of the maximum ratio of pressure and speed, the second input of which is connected to the speed meter, and the output is connected to the input of the solver.
Определение начала процесса прессовани осуществл етс следующим образом.The determination of the start of the pressing process is carried out as follows.
Движение главного плунжера будет холостым до тех пор, пока пресс-штемпель не коснетс слитка. Как только это произойдет , давление в главном цилиндре или боковых цилиндрах и скорость пресс-штемпел мгновенно возрастают и будут измен тьс по определенному закону.The movement of the main plunger will be idle until the ram touches the ingot. As soon as this happens, the pressure in the master cylinder or side cylinders and the ram speed will instantly increase and will change according to a certain law.
