Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the plane structure chart of a kind of embodiment of variable cross-section many circular arcs casted die mould that the utility model provides;
Fig. 2 is the plane structure chart of another angle of the casted die mould of many circular arcs shown in Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The utility model discloses a kind of variable cross-section many circular arcs casted die mould, and please refer to Fig. 1 and Fig. 2, wherein Fig. 1 is the plane structure chart of a kind of embodiment of variable cross-section many circular arcs casted die mould that the utility model provides; Fig. 2 is the plane structure chart of another angle of the casted die mould of many circular arcs shown in Fig. 1.Described variable cross-section many circular arcs casted die mould comprises the relative punch in interval and die.
Described punch comprises punch body 1 and convex mould base 2, and described convex mould base 2 is formed at described punch body 1 top.
Described die comprises die socket 3, ejector beam 4, retainer plate 5, two locating rack 6 and alignment pin 8, one end of described ejector beam 4 is inserted in described die socket 3, it is relative with described die socket 3 parallel interval that its other end supports described retainer plate 5, described two locating racks 6 are symmetrically set in the both sides of described retainer plate 5 and described die socket 3 is fixed in bottom, and it is inner that described retainer plate 5 is located at by described alignment pin 8.
The top of described retainer plate 5 comprises a groove, is provided with cushion block 7 in described groove, and described alignment pin 8 supports described cushion block 7.
The bottom of described punch body 1 comprises a projection, and described projection is arranged in described groove.
In the present embodiment, carry out die mould by hydraulic press to described variable cross-section many circular arcs casted die mould, more specifically, the power of described hydraulic press is drawn by following reckoning:
The longitudinal free bending of mould calculates:
P
1＝0.7*K*B*t
2*
b/(R+t)＝0.7*1.3*385*4*4*400/24＝74.7KN＝93.3t
Horizontal drawing pressure:
P
2＝0.9*B*t*δ
b＝0.9*1.5*0.004*400*10
6＝1.88*10
6N＝216t
Swaging power is calculated by free bending:
P＝93.3+216＝309.3t
Wherein, P
1---longitudinal free bending (N)
P
2---lateral tensile force (N)
B---bool width (mm)
δ
b---material strength limit (MPa)
T---bool thickness (mm)
The bending radius (mm) of R---bool
K---safety coefficient, generally gets K=1.3
Can find out from above calculating, carrying out die mould to described variable cross-section many circular arcs casted die mould is 5000KN hydraulic press.
During work, utilize 5000KN hydraulic press by described ejector beam 4 first by workpiece jack-up, height is determined by described locating rack 6, and the height of described locating rack 6 ensures that described retainer plate 5 top-surface camber nadir is higher than plane on die.
When described punch moves downward, described ejector beam 4 is motionless, 5000KN hydraulic press bottom knockout power has 1600KN, enough shaping, after described punch and described retainer plate 5 locking, then to compacted under, drawing side, namely workpiece upper end variable cross-section circular arc is separated shaping with side arc surface, upper end variable cross-section circular arc is that liftout power 1600KN is shaping on the lower, and side arc surface is by hydraulic press pressure drawing and moulding, so just can ensure the shaping of workpiece.
Because workpiece only turns over the limit of R20 on one side, can not be wrinkling, another side, can first open a gap, and unnecessary material is walked toward indentation, there, solves a lot of wrinkle problem of material.
In sum, variable cross-section many circular arcs casted die mould structure that the utility model provides is simple, cost is low, utilize drawing and bulging to combine technique, and design specialized mould ensures the formed precision of workpiece.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
