Problems solved by technology

[0002] At present, hydraulic or mechanical bending machines are generally used for bending long metal workpieces in China. The disadvantages of using 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 difficult to meet the requirements; 3) The operation requires high skill of the workers, and the replacement mold debugging cycle is long

Abstract

The invention relates to a high-straight-edge splint-type bending correction mould which comprises an upper template and a lower template; a male mould, a tapered wedge and a limit block are fixed on the upper template; a pin shaft and a female mould are arranged on the lower template; an open and close splint is arranged on the pin shaft; and one side of the female mould is provided with a fixedsplint which is fixed on the lower template. According to the bending correction mould disclosed by the invention, the working efficiency and precision can be improved; the investment cost of equipment is reduced; the utilization rate of the equipment is improved; and the mould is tightly locked with the splint through the tapered wedge so that the plastic deformation of materials can be restrained, and a workpiece is fetched and placed conveniently; a bottom touching correction method is adopted so that the workpiece has stable angle and flat bottom.

Description

technical field [0001] The invention relates to a mold, in particular to a high straight side splint type correction bending mold. Background technique [0002] At present, hydraulic or mechanical bending machines are generally used for bending long metal workpieces in China. The disadvantages of using 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 of the workpiece are high and 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 high straight-side splint type correction bending mold, which can be used universally in the field of bending, has a small footprint, low mold cost, high work efficiency, and good product quality , The angle is stable and pra...
