Claims (4)

1. Способ управления локальными усилиями в штампах листовой штамповки, содержащих верхнюю и нижнюю плиты, матрицу и пуансон, отличающийся тем, что в штампе устанавливается дифференцированное прижимное устройство, обеспечивающее во время формоизменения заготовки регулирование течения и перемещения металла с периферии в зону очага деформации посредством управления локальными усилиями.1. A method of controlling local forces in sheet metal stamping dies containing the upper and lower plates, a die and a punch, characterized in that a differentiated clamping device is installed in the stamp, which ensures the flow and movement of the metal from the periphery to the zone of the deformation zone during control of the workpiece by means of control local efforts. 2. Дифференцированное прижимное устройство, отличающееся тем, что прижим выполнен из секторов, закрепленных на плите, и каждый сектор прижима оснащен гидравлическим устройством передачи усилия по заданному алгоритму.2. Differentiated clamping device, characterized in that the clamp is made of sectors fixed to the plate, and each sector of the clamp is equipped with a hydraulic device for transmitting force according to a predetermined algorithm. 3. Дифференцированное прижимное устройство по п. 2, отличающееся тем, что гидравлическое устройство передачи усилия по заданному алгоритму, содержит корпус, шток с поршнем, в корпусе установлены кольца с внутренней поверхностью переменного сечения, которая с периферийной поверхностью поршня образует зазор, изменяющийся при перемещении поршня относительно корпуса.3. The differentiated clamping device according to claim 2, characterized in that the hydraulic force transmission device according to a predetermined algorithm, comprises a housing, a rod with a piston, rings with an internal surface of variable cross section, which forms a gap with the peripheral surface of the piston that changes when moving piston relative to the housing. 4. Дифференцированное прижимное устройство по п. 2, отличающееся тем, что гидравлическое устройство передачи усилия по заданному алгоритму, содержит корпус, шток с поршнем, шток выполнен полым с радиальными отверстиями, а на поршне установлено подвижное кольцо, имеющее возможность перекрывать отверстия в поршне, в корпусе установлена ось переменного сечения, один конец которой выполнен в виде поршня, размещенного в полости штока, при этом подвижное кольцо с осью переменного сечения образуют зазор, изменяющийся при перемещении полого штока с поршнем и кольцом относительно оси.4. The differentiated clamping device according to claim 2, characterized in that the hydraulic force transmission device according to a predetermined algorithm, comprises a housing, a rod with a piston, the rod is hollow with radial holes, and a movable ring is installed on the piston, having the ability to overlap the holes in the piston, an axle of variable section is installed in the housing, one end of which is made in the form of a piston located in the cavity of the rod, while the movable ring with the axis of variable section form a gap that changes when the hollow rod is moved and with the piston ring relative to the axis.
