Способ относится к области листовой штамповки и может быть использован во всех отраслях машиностроения для вытяжки деталей из листовых материалов на прессах простого и двойного действия. Способ включает размещение заготовки в штампе, прижим ее краевой части, формоизменения центральной части при помощи пуансона и матрицы. На начальных этапах формоизменения в краевой части заготовки, выступающей наружу за прижимные поверхности матрицы и прижима штампа, образуют складки, которые на последующих этапах формоизменения разглаживаются при втягивании между прижимными поверхностями матрицы и прижима, а после вытяжки служат частью поверхности готовой детали. В процессе разглаживания складок создается необходимое усилие торможения перемещению края заготовки, что обеспечивает получение качественных деталей и экономию листового проката.The method relates to the field of sheet metal stamping and can be used in all branches of mechanical engineering for drawing parts from sheet materials on presses of simple and double action. The method includes placing the workpiece in the stamp, clamping its edge part, shaping the central part with the help of a punch and die. In the initial stages of shaping, in the edge part of the workpiece, protruding outward beyond the pressing surfaces of the die and the die, they form wrinkles, which are smoothed out during the subsequent steps of deformation between the pressing surfaces of the die and the pressure, and after drawing, they are part of the finished part. In the process of smoothing the folds creates the necessary braking force to move the edge of the workpiece, which provides high-quality parts and saving sheet metal.
