Abstract
The invention discloses a stretch bending device, which comprises an upper die, clamps, springs and a lower die, wherein one clamp is arranged on one side of the upper die, one spring is mounted on the clamp, the other clamp is mounted on one side of the lower die, the other spring is mounted on the clamp, and the surface radian of the upper die corresponds to that of the lower die. By means of die assembly, the stretch bending device enables a stretch bending piece to curve and then uses the clamps to stretch and bend the stretch bending piece, so that the springback tendencies of the inner side and the outer side of the stretch bending piece are cancelled out, and the springback of the stretch bending piece is greatly reduced. Besides, according to the stretch bending device, the work cycle is about 2-3 minutes, the production efficiency is high, the structure is simple, and the work is stable and reliable.
Description
Technical field
The present invention relates to a kind of stretch bending device.
Background technology
At present; When the steel plate of making high-pressure bottle, boiler-steam dome, generator tube, hull and bone rib, various vessel, instrument and meter member and bin panel; Be to become certain curvature, shape and size and then drawing to sheet metal, tubing and shape bending; Material is when stretch bending, and the stress state of each several part is different in the deformed area.Metal in the middle of the cross section beyond the indeformable neutral line receives action of pulling stress, produces elongation strain.Neutral line produces compression with interior metal compression chord effect.Because the stress and strain of neutral line both sides metal is in the opposite direction; After load sheds; The metallic spring deformation-recovery of neutral line both sides is in the opposite direction, can cause spring-go in various degree, for the very big bool of relative bending radius; Because the deformed area major part is in elastic deformation, the elasticity of flexure can be very big.
Summary of the invention
Goal of the invention: the objective of the invention is in order to solve the deficiency of prior art, a kind of stretch bending device that reduces the bool resilience is provided, this apparatus structure is simple, and production efficiency is high, and working stability is reliable.
Technical scheme: in order to realize above purpose, a kind of stretch bending device of the present invention, it comprises patrix; Clip, spring and counterdie, a side of described patrix is provided with clip; Described clip is provided with spring; One side of described counterdie also is provided with clip, and described clip is provided with spring, and the surperficial radian of described patrix is corresponding with the surperficial radian of counterdie.
The middle of described upper die and lower die is provided with stretch bending spare.
Beneficial effect: a kind of stretch bending device provided by the invention behind matched moulds, makes stretch bending spare crooked; Again with clip with stretch bending spare stretch bending, make the resilience trend of the inside and outside both sides of bool cancel out each other, therefore can significantly reduce the resilience of bool; Be about 2-3min this turnaround of unit; Production efficiency is high, and this apparatus structure is simple, and working stability is reliable.
Description of drawings
Fig. 1 is the structural representation before the stretch bending of the present invention;
Fig. 2 is the structural representation behind the stretch bending of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, further illustrate the present invention.
As shown in Figure 1, a kind of stretch bending device of the present invention, it comprises patrix 1, clip 2, spring 3 and counterdie 4.
One side of described patrix 1 is provided with clip 2; Described clip 2 is provided with spring 3; One side of described counterdie 4 also is provided with clip 2; Described clip 2 is provided with spring 3, and the surperficial radian of described patrix 1 is corresponding with the surperficial radian of counterdie 4, and the middle of patrix 1 and counterdie 4 is provided with stretch bending spare 5.
As shown in Figure 2, when needs stretch bending spare 5 carries out stretch bending, at first; Patrix 1 carries out matched moulds with counterdie 4, makes the middle of patrix 1 and counterdie 4 be provided with stretch bending spare 5 along with patrix 1 surface bending with the surperficial corresponding radian of counterdie 4, with clip 2 bool 5 is clamped then; Again it is stretched, make the resilience trend of inside and outside both sides of bool 5 cancel out each other, therefore can significantly reduce the resilience of bool; Be about 2-3min this turnaround of unit; Production efficiency is high, and this apparatus structure is simple, and working stability is reliable.
Above-mentioned embodiment only is explanation technical conceive of the present invention and characteristics, its objective is to let to be familiar with these those skilled in the art and can to understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalents that spirit is made according to the present invention or modification all should be encompassed within protection scope of the present invention.
