Abstract
1. Способ изготовления гаечного ключа, включающий отрезку мерной заготовки, предварительную осадку головки, формирование фаски на торце, гибку заготовки, отличающийся тем, что образование гаечного ключа производят на четырех формообразующих позициях, при этом на первой позиции осуществляют первую предварительную осадку головки с одновременным редуцированием половины длины стержня, на второй позиции осуществляют вторую предварительную осадку головки и окончательное редуцирование стержня, на третьей позиции завершают окончательную осадку головки с образованием наружной конусной части и внутреннего многогранника с формированием фаски на хвостовике, на четвертой позиции производят гибку заготовки подвижным элементом матрицы. ! 2. Устройство для гибки, состоящее из матрицы, прижима для заготовки, отличающееся тем, что оно включает пуансон, состоящий из корпуса, в отверстии которого установлен плавающий за счет пружины прижим, а на торце жестко закреплен толкатель, кроме того, матрица имеет один подвижный элемент - поворотный рычаг, закрепленный на оси, которая смонтирована в непосредственной близости от торца матрицы, перпендикулярно ее продольной оси, на расстоянии, определяемом углом поворота рычага и заготовки при гибке. 1. A method of manufacturing a wrench, including the cut length of the measured billet, preliminary head upsetting, chamfering at the end, bending of the workpiece, characterized in that the formation of a wrench is carried out in four forming positions, while the first preliminary head upsetting is performed at the first position with simultaneous reduction half the length of the rod, in the second position carry out the second preliminary draft of the head and the final reduction of the rod, in the third position complete the final adku head to form an outer cone portion and an inner polyhedron to form a chamfer on the shank, at the fourth position produces bending of workpiece movable element matrix. ! 2. A device for bending, consisting of a matrix, a clamp for the workpiece, characterized in that it includes a punch consisting of a body, in the hole of which a spring clamp floating due to the spring is installed, and a pusher is rigidly fixed to the end, in addition, the matrix has one movable element - a pivot arm mounted on an axis that is mounted in the immediate vicinity of the end face of the matrix, perpendicular to its longitudinal axis, at a distance determined by the angle of rotation of the lever and the workpiece during bending.
