摘要： © This invention relates to a forming machine which is composed of several types of split dies in an upper die, thereby altering the length of the upper die in combination of the split dies. The upper die assembly has an upper die body mounted on the lower end of a ram, a number of upper split dies slidably inserted laterally of the die in the lower portion of the upper die body, a number of upper thin dies inversely mounted at the center of the upper split die group, a select finger driving mechanism provided at the front of the upper die body to slide the upper split dies in the lateral direction of the die, and an inverting mechanism provided at the rear of the upper die body to invert the upper thin dies of the desired number. The predetermined length of the die can be adjusted by driving the finger in response to the bending width of a work.

摘要： An apparatus for adjusting the tool length of a bending machine comprises a ram having a lower end, a top tool body mounted on the lower end of the ram, a bottom tool mounted below the top tool body, a top tool including a pair of central dies mounted longitudinally movably on the lower end of the ram, a plurality of upper split dies arranged outside the central dies and mounted reversibly to the upper die row, a plurality of thin upper dies inserted reversibly between the central dies and being thinner than the upper split die, and upper corner dies arranged on both left and right ends of the upper split die, a shift mechanism for sliding the central dies reversely at the central portion of the lower portion of the ram, a drive mechanism for sliding the upper corner dies to the longitudinally symmetrical positions of the lower portion of the ram, shafts pivotably disposed at the back of the central dies and upper corner dies, a plurality of the upper split dies wedged to the shafts and reversed in pivoting of the shaft to be selectively inserted between said central die and upper corner die, a wedge releasing mechanism for releasing the upper split die from the wedge to be received in the corresponding upper die in pivoting the shaft, and a mechanism for selecting the number of the thin upper dies supported by the shaft at the back of the central dies so as to be reversed.
