Specific embodiment
Below according to accompanying drawing 1, provide presently preferred embodiments of the present invention, and be described in detail, make to be better understood when this The function of invention, feature.
Refer to Fig. 1, Fig. 3, a kind of male flange mould of the embodiment of the present invention, including:One punch 1 and a die 2, its In, punch 1 includes a mould body 11, a staking punch 12 and a base 13, and staking punch 12 is arranged at mould body 11 first end, and base 13 sets It is placed in mould body 11 second end;Staking punch 12 includes a staking punch body 121 and the convex tendon being formed at staking punch body 121 both sides 122, the outer radial of the circular in cross-section of staking punch body 121 and staking punch body 121 gradually subtracts away from the direction of mould body 11 Little, staking punch body 121 forms one first chamfering 123 away from one end of mould body 11.
Staking punch 12 is used for being stamped and formed out flange hole, and base 13 is used for the fixation of punch 1, is formed at staking punch body 121 The convex tendon 122 of both sides is used for directly forming the groove of flange in the hole both sides in punching press, without following process.Staking punch body 121 outer radial is gradually reduced away from the direction of mould body 11, and staking punch body 121 falls away from one end formation one first of mould body 11 Angle 123, for forming the flange of flange in punching press.
In the present embodiment, the height of staking punch body 121 is 12~13mm.The radius of the first chamfering 123 is 5~6mm.? In other embodiment, the radius of the height of staking punch body 121 and the first chamfering 123 can adjust according to the actual requirements.
Refer to Fig. 2, mould body 11 forms a circumferential limiting section 111.Circumferential limiting section 111 is used for realizing to convex in punching press Mould 1 circumferentially positioned.
In the present embodiment, die 2 depression forms a workpiece die cavity 21, and workpiece die cavity 21 medial recess forms a flange die cavity 22, the shape of flange die cavity 22 is coordinated with staking punch 12, when flange die cavity 22 is stretched in staking punch 12 end, flange die cavity 22 with Form the gap of a fixed thickness between staking punch 12;The connecting portion of flange die cavity 22 and workpiece die cavity 21 forms one second chamfering 23.
Die 2 is used for preparing flange with punch 1.Workpiece die cavity 21 is used for being stamped and formed out flange profile, flange die cavity 22 are used for being stamped and formed out flange flange with punch 1 cooperation.Second chamfering 23 using so that processing after obtain flange flange outside Side bottom forms corresponding chamfering structure, prevents flange flange exterior bottom from forming folding or crackle in punching course, strengthens The intensity of flange flange.
Further improvement of the present invention is, the radius of the second chamfering 23 is 1.25~1.75mm.
Refer to Fig. 4, a kind of male flange preparation method based on male flange mould of the present invention of the present invention, including step Suddenly:
S1:By punching and blanking working procedure processing one plate, obtain a roughing part, the peripheral shape of roughing part with required The peripheral shape preparing flange is identical, and forms an interstitial hole in the middle part of roughing part;
S2:Using male flange mould, interstitial hole is carried out with backward extrusion and form flange flange, flange flange passes through backward extrusion Once formed;
S3:Rush the flange hole that the clout inside interstitial hole forms inner wall smooth, obtain a male flange.
Refer to body Fig. 1, Fig. 3 and Fig. 5, for example, in actual production, male flange mould installion can be filled in a pressing mold Put, die arrangement mainly includes cope match-plate pattern 4, lower template 5, die block 6, die backing plate 7, punch retainer 8, intermediate plate 9 With base plate 10.Die 2 is fixed on die backing plate 7 die block 6, and die block 6 and die backing plate 7 are by bolt even Connect and be fixed on cope match-plate pattern 4.Punch 1 is arranged at the peace that punch retainer 8, intermediate plate 9, base plate 10 and lower template 5 cooperatively form In tankage.First pass through die arrangement and one plate 11 is punched out with blanking operation acquisition roughing part, in the present embodiment, plate 11 thickness are 10mm;Then by press feet oil cylinder, upwardly punch 1 extrudes roughing part, coordinates backward extrusion with die 2 Go out flange flange.When male flange mould is opened, formed flanges flange is released die 2 by the 12 promotion dowel steels 12 that re-packed from above. In the present embodiment, the radius of the first chamfering 123 is 5.85mm, and the height of staking punch body 121 is 12.49mm.Second chamfering 23 Radius control in 1.25~1.75mm, with prevent fold and crackle.A diameter of 55mm of flange hole.
Above in association with accompanying drawing embodiment, the present invention is described in detail, those skilled in the art can be according to upper State and bright the present invention is made with many variations example.Thus, some details in embodiment should not constitute limitation of the invention, this Invention is by the scope being defined using appended claims as protection scope of the present invention.
