The processing method of a kind of petal special shape of the present invention, its difference with the prior art is: described processing method comprises the steps: a, selects corresponding metal plate material according to the petal special shape of required making; B, shape groover according to the petal special shape of required making on metal plate material are slotted, and the shape of fluting is V-type groove, U-type groove or Y type groove; C, carry out bending machining successively along each cell body, each cell body reaches setting bending angle after 1-2 bending, and whole cell body has bent rear formation petal special shape.
When fluting shape is V-type groove, when cell body bends for external corner, V-type angle mainly contains two kinds, a kind of V-type included angle is 100 °, be 90 °-179 ° curved for bending angle, another kind of V-type included angle is 140 °, is 45 °-90 ° curved for bending angle; When cell body be used for inner corner trim bend time, the V-type angle of V-type fluting is 100 °, and for bending between 30 °-179 ° bending machining at any angle, and V-type is recessed at the back side of bending inner corner trim.Fluting shape is when being V-type groove, and when cell body is used for bending decorative metals profile shapes, the degree of depth of V-type fluting has two kinds, and a kind of be the degree of depth of fluting is 1/2nd of thickness of slab, and another kind is the degree of depth of fluting is 2/3rds of thickness of slab; When cell body be used for bending structure petal special shape time, V-type fluting the degree of depth have two kinds, a kind of be fluting the degree of depth be 1/3rd of thickness of slab, another kind be fluting the degree of depth be 1/2nd of thickness of slab.Fluting shape is when being V-type groove, and when cell body is for bending the petal special shape of two end equal sections, adjacent V-type groove is identical with the interval width distance between V-type groove; When cell body is for bending the petal special shape of two ends not equal section, i.e., during the petal special shape of concentric reducer end face, adjacent V-type groove is not identical with the interval width distance between V-type groove.Material thickness difference is bent due to remaining after metal blank fluting, bending force required when bending is also different, when the degree of depth of the corner V-type groove be bent is 2/3rds of thickness of slab, the only thickness of slab of surplus 1/3rd, because required bending force is less than the bending force of residue 1/2nd thickness of slab, so other in type bent angles can not be had influence on when bending this bent angle.
Fluting shape is when being U-type groove, and when cell body is used for bending decorative metals profile shapes, the degree of depth of U-shaped fluting has two kinds, and a kind of be the degree of depth of fluting is 1/2nd of thickness of slab, and another kind is the degree of depth of fluting is 2/3rds of thickness of slab; When cell body be used for bending structure petal special shape time, the degree of depth of U-shaped fluting has two kinds, a kind of be fluting the degree of depth be 1/3rd of thickness of slab, another kind be fluting the degree of depth be 1/2nd of thickness of slab.Fluting shape is when being U-type groove, and when cell body is for bending the petal special shape of two end equal sections, the interval width distance between adjacent U-type groove with V-type groove is identical; When cell body is for bending the petal special shape of two ends not equal section, i.e., during the petal special shape of concentric reducer end face, adjacent U-type groove is not identical with the interval width distance between U-type groove.
Fluting shape is when being Y type groove, and when cell body is used for bending decorative metals profile shapes, the degree of depth of Y type fluting has two kinds, and a kind of be the degree of depth of fluting is 1/2nd of thickness of slab, and another kind is the degree of depth of fluting is 2/3rds of thickness of slab; When cell body be used for bending structure petal special shape time, Y type fluting the degree of depth have two kinds, a kind of be fluting the degree of depth be 1/3rd of thickness of slab, another kind be fluting the degree of depth be 1/2nd of thickness of slab.Fluting shape is when being Y type groove, and when cell body is for bending the petal special shape of two end equal sections, adjacent Y type groove is identical with the interval width distance between Y type groove; When cell body is for bending the petal special shape of two ends not equal section, i.e., during the petal special shape of concentric reducer end face, adjacent Y type groove is not identical with the interval width distance between Y type groove.
In step C, bender or forcing press carry out bending machining successively along each cell body, bending patrix adopts straight mould, return flanging die, and tack mould; Bending counterdie adopts 88 ° of single groove V-type moulds and 58 ° of single groove V-type moulds.When metal blank bends along cell body, conventional 88 ° of single groove V-type moulds bend 90 ° curved; 58 ° of single groove V-type moulds are adopted to bend 60 °-90 ° curved.
In enforcement, the petal special shape of Fig. 1, becomes the metal plate material before bending in Fig. 2 after deployment.Metal plate material first processes equidistant V-type groove by geomery shown in Fig. 1, groove 301 as shown in Figure 2, groove 302, groove 303, groove 304, groove 306, groove 307, equidistant broadside of the corresponding petal special shape of the distance between groove with groove and narrow limit; Because the petal special shape shown in Fig. 1 belongs to decorative metals profile shapes, so the groove depth of groove 301, groove 302, groove 303, groove 304, groove 306 controls for thickness of slab 1/2nd.The groove depth of groove 307 controls for thickness of slab 2/3rds.
Then on metal plate material, the required size processing V-type groove non-equally of petal special shape is pressed, groove 305 as shown in Figure 3.The large end of plane and small end on the corresponding petal special shape of the spacing that differs in size between groove 305 with groove 307, the groove depth of groove 305 controls for thickness of slab 1/2nd.
In fig. 2, the outward appearance external corner due to shown petal special shape is all 90 °, so the V-type angle of the V-type fluting of external corner is all processed into 100 °, namely the V-type angle of groove 302, groove 304, groove 305, groove 306, groove 307 is all processed into 100 °.
In fig. 2, although the outward appearance inner corner trim one of shown petal special shape is greater than 90 °, one is less than 90 °, because V-type fluting is all at the back side of bending inner corner trim, so inner corner trim V-type fluting V-type angle also unification be processed into 100 °, namely the V-type angle of groove 301, groove 303 is all processed into 100 °.
After fluting work completes, start to carry out bending machining.
In Fig. 7-Figure 15, the first patrix is 58 ° of straight moulds, and the second patrix is 88 ° of return flanging dies, and the 3rd patrix is tack mould.First counterdie is 88 ° of single groove V-type moulds, and the second counterdie is 58 ° of single groove V-type channel moulds.
Fig. 7 is that the first fluting not in place 90 ° bends.Bent angle is that outward appearance is less than 90 ° of inner corner trims herein, and bending from simulation, bent angle puts in place as a step bends herein, the cause that follow-up bending meeting is interfered because of mould, and cannot implement to bend.So the first fluting place bending can only first bend in 90 °, mend again later and be bent to position.
Fig. 8, Fig. 9, Figure 10 be respectively the second fluting, the 3rd fluting, the 4th fluting bending.Before bending, machined V-type groove, under the effect of bending force, bending position can not depart from the center of V-type groove, and therefore easily accurate positioning, can ensure the appearance and size of petal special shape.
It is bending that Figure 11 is that the benefit of the first fluting puts in place, uses 58 ° of single groove V-type moulds instead, and namely the second counterdie carries out being less than the bending of 90 ° of angles.
Figure 12 is the bending of the 5th fluting.Figure 13 is the bending of the 6th fluting, and from figure, right figure is known, and by the restriction of the shape and size of petal special shape, the first patrix cannot complete the bending of the 6th fluting, needs to use 88 ° of return flanging dies instead, and namely the second patrix just can carry out 90 ° of angular distortions of the 6th fluting.
Can see in fig. 2: the 7th fluting is that the last of petal special shape bends operation together, be also that the most difficult enclosed type bends.Limit by mould, bend herein and two steps must be divided to carry out.
Figure 14 is 90 ° not in place bending of being greater than of the 7th fluting.
Figure 15 is that the benefit of the 7th fluting puts in place bending, and in fig .15, need to use tack patrix instead, namely the 3rd patrix puts in place bending to the benefit that the 7th fluting carries out 90 ° of angles.Groove depth due to the 7th fluting controls for thickness of slab 2/3rds, be greater than the groove depth of other all bent angles, so the resistance to bending of the 7th fluting is minimum, under the pressure of tack patrix, other bent angles can maintain original shape, the bent angle at the 7th fluting place is only had to continue distortion, until bend at an angle of 90.Because the 7th fluting place residue thickness of slab be after grooving only raw sheet thick 1/3rd, so the springback angle of the bent angle at the 7th fluting place after bending is also very little, large resilience can not be produced, easily form the bent angle closed, thus reached the object being processed into petal special shape.
