Abstract

FIELD: plastic working of metals. SUBSTANCE: stamp has punch with side undercuttings and die with two auxiliary fixed halves positioned at a distance from punch, with space between them being adjusted. Auxiliary die halves serve to bend parts. Space adjustment range is triple the length of part radius development portion. EFFECT: reduced production time, improved quality of parts by simplified construction of bending device and simplified bending adjustment process. 2 cl, 1 dwg

Изобретение относится к области обработки металлов давлением и может быть использовано при гибке П-образных деталей с учетом нестабильного пружинения заготовок. Цель изобретения: сокращение затрат на изготовление штампа и повышение качества деталей путем упрощения конструкции перегибающего устройства и регулирования перегиба. Штамп содержит пуансон с боковыми поднутрениями, а также матрицу и отличается тем, что на матрице установлены две дополнительные неподвижные полуматрицы с регулируемым зазором по отношению к пуансону, которые выполняют функцию перегибающего устройства. Диапазон регулировки зазора равен утроенной длине развертки радиусной части детали.The invention relates to the field of metal forming and can be used when bending U-shaped parts, taking into account the unstable springing of the workpieces. The purpose of the invention: reducing the cost of manufacturing a stamp and improving the quality of parts by simplifying the design of the bending device and adjusting the bend. The stamp contains a punch with lateral undercuts, as well as a matrix, and is characterized in that two additional fixed semi-matrices are installed on the matrix with an adjustable clearance relative to the punch, which perform the function of a bending device. The clearance adjustment range is three times the sweep length of the radius of the part.
