Description
Technical field
The Cold-forming process of a kind of bent angle of metal plate of the present invention.
Background technology
The method of sheet metal bent angle processing, has hot and cold processing two kinds of modes: cold stamping, welding and Making mold method.Metal veneer, in order to reduce load-bearing and gain in strength, adopts the lid form that four limits are strengthened usually, adopts the method by welding joint close after casting or bending more at present.There is its weak point these two kinds of aspects, and casting needs at substantial electric energy, the raw material such as coal, also needs special casting mould, a kind of specification mould, and production cost is large, produces dumb.Weld the method for joint close after bending again, require high to the technical merit of workman, production efficiency is low, and welding welding rod price is high, and produces harmful waste gas, very not environmentally.Number of patent application 02129918.8 discloses a kind of processing method of bent angle of metal plate, adopt and slot at the knuckle place of metallic plate, by metallic plate along chine bending, make bent angle, the bent angle of this method processing reduces greatly in fluting place mechanical strength, open a linear V-shaped groove at plate surface, need special processing equipment, higher to workman's technical requirement.The bent angle made after bending, chine place is that void hangs together, and be not the overall structure of one, stationarity is bad, and mechanical strength is not high.
Summary of the invention
The object of the present invention is to provide a kind of Cold-forming process of bent angle of metal plate, do not cut bottom surface; Can not cause bottom surface scar, can not lower bottom surface intensity, intensity is higher than bottom surface grooving method.Can in order to avoid welding joint close and the robustness of bent angle is good, intensity is high, and smooth surface is flawless.
Production efficiency is high, labour intensity is little, greatly reduces production cost than traditional approach, has disruptive technology innovation than processing mode in the past.
For achieving the above object, technical solution of the present invention is:
A Cold-forming process for bent angle of metal plate, the step comprised has
1) sheet metal both sides are bent into U-shaped sheet metal, both sides are facade, and bottom is bottom surface;
2) facade curved line position, U-shaped sheet metal both sides is determined;
3) output the isosceles right triangle open slot of a pair square apex angle in lower end in facade folding line position, both sides, open slot is just positioned on bottom surface, does not cut bottom surface; Can not cause bottom surface scar, can not lower bottom surface intensity, intensity is higher than bottom surface grooving method.
4) along the outside of two isosceles right triangle open slots of the same side facade, vertically sheet metal is cut off;
5) corner position bending U-shaped sheet metal bottom open slot, makes bottom surface vertical with bending side;
6) by extruding angulation system, from upper and lower, bent angle both sides extrude simultaneously, rolled metal plate bent angle, the shape material angle after roll extrusion is made to be all right angle on three, by roll-in repeatedly, the slow deformation of stretching bent angle, again whole Golden Elephant arrangement, make bent angle not occur slight crack, be fused to entirety, intensity is high.
The step also comprised has: deburring, repaiies burr.
According to technical scheme provided by the invention, it has the following advantages relative to prior art tool:
The Cold-forming process of bent angle of metal plate provided by the invention and special metallic plate angle forming machine, comprise bending forming system and extruding angulation system two parts, complete bending and extruded two steps, by the reciprocating top board extruding in horizontal aspect U-board material, make it to become square, extruding angulation system is by the extruding of pressing plate and steel bobbin, rolling makes shaping metal veneer corner combine together, adopting Cold-forming process, can to reach the robustness exempting to weld joint close and bent angle good, intensity is high, smooth surface is flawless, finished appearance is attractive in appearance, intensity is reliable.

Detailed description of the invention
A Cold-forming process for bent angle of metal plate, the step comprised has
1) sheet metal both sides are bent into U-shaped sheet metal, both sides are facade, and bottom is bottom surface;
2) facade curved line position, U-shaped sheet metal both sides is determined;
3) output the isosceles right triangle open slot of a pair square apex angle in lower end in facade folding line position, both sides, open slot is just positioned on bottom surface, does not cut bottom surface;
4) along the outside of two isosceles right triangle open slots of the same side facade, vertically sheet metal is cut off;
5) corner position bending U-shaped sheet metal bottom open slot, makes bottom surface vertical with bending side;
6) by extruding angulation system, from upper and lower, bent angle both sides extrude simultaneously, rolled metal plate bent angle, the shape material angle after roll extrusion is made to be all right angle on three, by roll-in repeatedly, the slow deformation of stretching bent angle, again whole Golden Elephant arrangement, make bent angle not occur slight crack, be fused to entirety, intensity is high.
The step also comprised has: deburring, repaiies burr.
Above-mentioned processing method the 5th, in six steps, use following special equipment of the present invention:
