Embodiment
In order that those skilled in the art more fully understands technical scheme, below in conjunction with accompanying drawing to this hair
It is bright to be further detailed.
It is a kind of flanging die provided in an embodiment of the present invention with reference to shown in Fig. 1, Fig. 2 and Fig. 4, including upper bolster 1, under
Die holder 2, the flange cavity plate 4 installed in the flanging die 3 of the bottom of upper bolster 1 and on die shoe 2, flange cavity plate 4
Medial surface is its forming surface, and the top of forming surface is provided with a composing type rod 5, and moulding stick 5 is used for plate flanging and restriking, shaping
Rod 5 ensures its intensity using heat treatment, wherein, the horizontal top for being embedded in forming surface respectively of moulding stick 5 and can be in forming surface
Upper to rotate, the rolling surface of respective forming surface is is protruded in the relative side of two moulding sticks 5, and rolling surface coordinates flanging die 3 to blank
12 flange.
When blank 12 is moved in flange cavity plate, rolling surface is in rolling contact with blank 12 all the time, and rolling surface replaces flange recessed
Mould 4 coordinates to work the flange of blank 12 during flanging die, meanwhile, when the workpiece after flange takes out, rolling surface, which has to be oriented to, to be made
With.The use of rolling surface avoids turn-up process linear contact lay shaping (common face contact), makes the more fairing of flange face, the shaping of its flange
Effect is good；Meanwhile, rod is rolled due to being installed using inserted, is facilitated its dismounting and is changed.
In the present embodiment, the micro protrusion forming surface of rolling surface, to ensure during flange, blank is moved along flange cavity plate, wherein,
In the present embodiment, rolling surface is higher by the forming surface 2mm of flange cavity plate 4.
Specifically, with reference to shown in Fig. 1 and 3 to Fig. 5, in the present embodiment, one is offered respectively on the top of forming surface inside
The open slot of opening, open slot it is horizontal run through flange cavity plate 4, to facilitate the installation and taking-up of moulding stick, moulding stick 5 is arranged on
In open slot, dismounting debugging is facilitated its installation.One group of limiting plate 6 is further fixed on die shoe 2, limiting plate 6 is covered respectively
It is in the openend of open slot, moulding stick 5 is spacing in open slot.Meanwhile, in each limiting plate 6 towards the side top of cavity plate
A hook material pawl 7 is respectively fixed with, hooks and expects that pawl 7 is located at the top side of flange cavity plate 4 and horizontal-extending to the inner side of flange cavity plate, it can
Its installation with limiting plate 6 is realized by hooking material pedestal 71, when being stuck in after blank shaping on punch-pin, upper bolster 1 passes through flange
Punch-pin 3 drives molding part to move upwards, when moving to hook material 7 position of pawl, hooks material pawl 7 and catches on molding part, it is to avoid it is with upper mould
Continue to move.Certainly, this function also can be by setting telescopic ejector 31 to realize in the bottom of flanging die 3.
The present apparatus is movable in flange cavity plate to be provided with retainer core 8, and after the completion of blank shaping, retainer core 8 works
By the parts ejection after shaping, when retainer core 8 moves to the top of flange cavity plate 3, both sides and the rolling surface of retainer core 8 are rolled
Dynamic contact, due to the protruding point that rolling surface is forming surface, therefore, the mode that is in rolling contact of retainer core 8 has not only been oriented to retainer core
Installation, meanwhile, the problem of it also avoids flange cavity plate 4 to its movement interference.Wherein, it is provided with supporting plate in the bottom of die shoe 2
81, supporting plate 81 is connected by push rod 82 with retainer core 8, and retainer is realized in motion to driving retainer core 8 upwards, wherein, supporting plate 81 and top
The mode of bar 82 is the conventional design of mould.
Limited block 6 is additionally provided with the surrounding of flange cavity plate 4, limited block 6 is used to position unfashioned blank 12, to ensure into
Type position, wherein, blank 12 is arranged on flange cavity plate 4 and its surrounding is contacted with limited block 6.
Furthermore, it is understood that as shown in figure 4, multiple guide pillars 10 are surrounded by the top of die shoe, in the bottom of upper bolster
Provided with multiple guide pin bushings 11 being engaged with the guide pillar, coordinated by guide pillar 10 and guide pin bushing 11 and motion guide is carried out to upper mould.
Specific work process is as follows：Die shoe 2 is arranged on lathe first, the ejection of lathe push rod forces the band of supporting plate 81
The dynamic jack-up retainer core 8 (neat as flange cavity plate) of push rod 82, retainer core 8 and flange cavity plate 3 are placed by presser by blank
On, blank is positioned by locating piece 6, upper mould is descending, first the contact of flanging die 3 blank 12, match somebody with somebody combined pressure with retainer core 8
Tight blank 12, upper mould is continued traveling downwardly, by flange cavity plate 4 flanging forming of moulding stick 5, is completed after flanging forming, lathe top
Bar jack-up, forces supporting plate 81 to drive the jack-up retainer core (neat as flange cavity plate) of push rod 82, and the flanging die 3 of upper bolster is synchronous
Retract, while ejector 31 is to overturning process part discharging, to prevent overturning process part card flanging die, carried out by hooking material pawl 7
Rigid anti-sticking, it is artificial to take out overturning process part, complete a flange operation.
The flanging die, which realizes turn-up process linear contact lay shaping (common face contact), makes the more fairing of flange face, solves conventional
Overturning process part because insert piece is produced, safeguard after plucking problem of appearance and repair welding maintenance and debugging rectification cost is high by flange insert
Problem.
Some one exemplary embodiments of the present invention are only described by way of explanation above, undoubtedly, for ability
The those of ordinary skill in domain, without departing from the spirit and scope of the present invention, can be with a variety of modes to institute
The embodiment of description is modified.Therefore, above-mentioned accompanying drawing and description are inherently illustrative, should not be construed as to the present invention
The limitation of claims.
