Claims (7)

1. Пуансон для гибочного прессования, используемый в устройстве для гибочного прессования, содержащем прессовые матрицы, расположенные через интервалы вдоль направления подачи листового материала для поддержания листового материала в двух позициях, и указанный пуансон, выполненный с возможностью перемещения в направлениях к прессовым матрицам и от них и последовательного прессования листового материала, поддерживаемого прессовыми матрицами вдоль направления подачи, для осуществления сгибания,1. A bending press punch used in a bending press device comprising press dies spaced at intervals along the feed direction of the sheet material to maintain the sheet material in two positions, and said punch configured to move in and out of the press dies and sequentially pressing the sheet material supported by the press dies along the feed direction to effect bending, отличающийся тем, что он имеет головку пуансона, непосредственно контактирующую с листовым материалом для прессования листового материала, и опору пуансона, соединенную с задней частью головки пуансона и поддерживающую головку пуансона, при этом головка пуансона выполнена с рабочей поверхностью, имеющей центр рабочей поверхности, совпадающий с осью опоры пуансона, и образованной неравномерной дугой окружности, радиус которой в центральной области в направлении по ширине является максимальным радиусом.characterized in that it has a punch head directly in contact with the sheet material for pressing the sheet material, and a punch support connected to the back of the punch head and supporting the punch head, wherein the punch head is made with a working surface having a center of the working surface coinciding with the axis of the support of the punch, and formed by a non-uniform arc of a circle whose radius in the Central region in the direction of width is the maximum radius. 2. Пуансон по п. 1, в котором неравномерная дуга окружности представляет собой непрерывную дугу окружности или разрывную дугу окружности, полученную посредством объединения по меньшей мере двух дуг, имеющих разные радиусы.2. A punch according to claim 1, wherein the non-uniform circular arc is a continuous circular arc or a discontinuous circular arc obtained by combining at least two arcs having different radii. 3. Пуансон по п. 1, в котором неравномерная дуга окружности включает в себя эвольвенту.3. A punch according to claim 1, wherein the non-uniform circular arc includes an involute. 4. Пуансон по п. 2, в котором непрерывная дуга окружности или разрывная дуга окружности включает в себя основную дугу окружности, радиус которой соответствует внутреннему диаметру получаемой стальной трубы, имеющую равные боковые рабочие участки относительно центра рабочей поверхности, и вспомогательную дугу окружности, проходящую от краевых участков основной дуги окружности, радиус которой меньше, чем радиус основной дуги.4. The punch according to claim 2, in which a continuous circular arc or a discontinuous circular arc includes a main circular arc, the radius of which corresponds to the inner diameter of the resulting steel pipe having equal lateral working sections relative to the center of the working surface, and an auxiliary circular arc passing from edge sections of the main arc of a circle whose radius is less than the radius of the main arc. 5. Пуансон по любому из пп. 1-3, в котором область неравномерной дуги окружности, в которой дуга окружности вносит основной вклад в сгибание, имеет рабочую ширину, составляющую менее 0,90 от шага подачи листового материала.5. Punch according to any one of paragraphs. 1-3, in which the region of a non-uniform circular arc, in which the circular arc makes the main contribution to bending, has a working width of less than 0.90 from the pitch of the sheet material. 6. Пуансон по п. 4, в котором область непрерывной дуги окружности или разрывной дуги окружности, в которой образована основная дуга окружности, имеет рабочую ширину, составляющую менее 0,90 от шага подачи листового материала.6. The punch according to claim 4, in which the area of a continuous arc of a circle or a discontinuous arc of a circle in which the main arc of a circle is formed has a working width of less than 0.90 from the pitch of the sheet material.
