Novel curved die straightening device

Abstract

The invention relates to a novel curved die straightening device. The novel curved die straightening device comprises an upper die plate and a lower die plate, wherein a male die, a tapered wedge and a limiting block are fixed on the upper die plate; a pin shaft and a female die are arranged on the lower die plate; an opening-closing clamp plate is arranged on the pin shaft; a fixed clamp plate is arranged on one side of the female die; the fixed clamp plate is fixed on the lower die plate. Through the novel curved die straightening device, operation efficiency and accuracy can be improved; equipment investment cost is reduced; the utilization rate of the equipment is increased; the die is locked by the tapered wedge and the clamp plate; the plastic deformation of the material can be restrained; the workpiece can be conveniently taken and placed; a bottom straightening method is adopted, so that the angle of the workpiece is stable, and the bottom of the workpiece is flat.

Description

technical field [0001] The invention relates to a mold, in particular to a novel correction bending mold device. Background technique [0002] At present, hydraulic or mechanical bending machines are generally used for bending long metal workpieces in China. The disadvantages of bending machines are: 1) poor versatility of equipment; low efficiency, high cost, low precision, and large floor space; 2) The angle, non-perpendicularity and appearance requirements of the workpiece are high and it is difficult to meet the requirements; 3) The operation requires high skill of the workers, and the replacement mold debugging cycle is long. Contents of the invention [0003] The present invention overcomes the deficiencies of the prior art, and proposes a new type of correction bending mold device, which can be used universally in the field of bending, has a small footprint, low mold cost, high work efficiency, good product quality, and stable angle practical. [0004] The technic...
