Abstract
The invention relates to a segment difference forming die, in particular to a forming die for folding a flat plate to form a segment difference surface. The segment difference forming die comprises an upper die and a lower die. The upper die comprises a striking head, a die handle, a spring, a guide sleeve and an upper roller. The lower die comprises a lower roller and a die holder. On an axial section of the upper roller, the roller surface of the upper roller is in a fold line shape consistent with the shape of the segment difference surface. The shape of the lower roller is consistent with that of the upper roller. The width of the lower roller is larger than that of the upper roller. The die of the invention is small, has low cost, is particularly suitable for small scale production and can be used as a die for forming the segment difference in a multistation combination operation system of a numerical control turrent punch press.
Description
Technical field
The present invention relates to a kind of mould, relate in particular to a kind of mould with the roll extrusion section of folding difference face with the flat board section of folding difference face.
Background technology
The requirement of punching molding is not only arranged on now a lot of workpieces, also need to process some sections difference face sometimes.Generally speaking, processing sections difference face is to adopt the bender moulding, but some medium and small processing enterprises are difficult to dispose various machining tools comprehensively.As: some Sheet Metal Processing enterprise has NC turret punch machine, but lacks bender, and at this moment, they just need seek cooperation processing, and one causes the lengthening of production cycle back and forth, and production task is finished in serious may being difficult on time; Two, some section difference face (non-90 °) needs the special mould that folds, and can cause the increase of their cost.
Summary of the invention
The present invention is directed to above problem, it is little to provide a kind of mould to drop into, and is fit to numerical control press, and the high section difference mould of machining accuracy.
Technical scheme of the present invention is: comprise upper die and lower die, patrix comprises attacking head, die shank, spring, guide pin bushing, upper roller, counterdie comprises bottom roller and die holder, on the axial cross section of upper roller, the wheel surface of upper roller is and has a broken line shape of coincideing with section difference face shape, bottom roller shape and upper roller shape be wedging mutually, and the width of bottom roller is greater than the width of upper roller.
Described upper roller and/the bottom roller wheel face is a matsurface.
Automatic feeding function and the controlled function of stroke that the present invention utilizes numerical control press to have can be to the difference processing of the flat board section of carrying out, automatic feeding with plate along straight line send to, drift remains on certain amount of feeding and can the section of realization differ from moulding simultaneously.With respect to the bender of bender, mould of the present invention is small and exquisite, and cost is low, especially is fit to small lot batch manufacture.The present invention can be used as NC turret punch machine multistation integration of operation system stage casing difference forming mould.

The specific embodiment
The present invention as shown in Figure 1, 2, comprise upper die and lower die, patrix comprises attacking head, die shank 1, spring 2, guide pin bushing 3, upper roller 4, counterdie comprises bottom roller 6 and die holder 7, on the axial cross section of upper roller 4, the wheel surface of upper roller 4 is and has the broken line shape that the section difference face shape with plate 5 matches, and bottom roller 6 shapes and upper roller 4 shapes are wedging mutually, and the width of bottom roller 6 is greater than the width of upper roller 4.
Skid when preventing feeding, described upper roller 4 and/bottom roller 6 wheel faces are matsurface.
Claims (2)
1. section difference mould, comprise upper die and lower die, patrix comprises attacking head, die shank, spring, guide pin bushing, upper roller, counterdie comprises bottom roller and die holder, it is characterized in that on the axial cross section of upper roller, the wheel surface of upper roller is and has a broken line shape of coincideing with section difference face shape, bottom roller shape and upper roller shape be wedging mutually, and the width of bottom roller is greater than the width of upper roller.
