RU95105775A - Method of regulation of press lower pusher and device for its embodiment - Google Patents

Abstract

FIELD: plastic metal working. SUBSTANCE: the offered method of regulation of pusher 2 is executed by turning connecting member 14 of component parts of connecting rod 1 of pusher motion drive to change in this way the length of connecting rod 1 with simultaneous regulation of time of operation of air cylinder 20 which holds pusher 2 in the upper position. The device for embodiment of the offered method has pusher 2 with drive for its motion in form of levers 8 and 9, tie-rods 10 and 11 connected by connecting rod 1 with crank 12 of the main actuating mechanism. In this case, axles of crank 12 and connecting rod 1 are turned relative to each other through a constant angle. Connecting rod 1 is assembled of parts by means of connecting members 14 provided with threads of opposite directions. EFFECT: higher efficiency. 2 cl, 4 dwg

Изобретение относится к обработке металлов давлением, в частности к устройствам систем выталкивания прессов. Способ регулировки выталкивателя осуществляют поворотом соединительного элемента составных частей шатуна привода перемещения толкателя, изменяя таким образом длину шатуна, а также регулируют при этом время срабатывания пневмоцилиндра, удерживающего толкатель в верхнем положении. Устройство для осуществления предлагаемого способа содержит толкатель с приводом его перемещения в виде рычагов и тяг, связанным посредством шатуна с кривошипом основного исполнительного механизма, причем ось кривошипа и ось шатуна развернуты между собой на постоянный угол, а шатун выполнен составным, части которого смонтированы между собой при помощи соединительного элемента, который снабжен резьбами противоположных направлений.The invention relates to the processing of metals by pressure, in particular to devices of press ejection systems. The method of adjusting the ejector is carried out by turning the connecting element of the connecting rod components of the connecting rod of the pusher movement drive, thereby changing the length of the connecting rod, and also controlling the response time of the pneumatic cylinder holding the pusher in the upper position. A device for implementing the proposed method comprises a pusher with a drive of its movement in the form of levers and rods connected by a connecting rod with the crank of the main actuator, the crank axis and the connecting rod axis being turned to each other at a constant angle, and the connecting rod is made integral, parts of which are mounted together help of the connecting element, which is provided with threads in opposite directions.
